It also serves the purpose of water quality preservation. Custom sizes tailored to the site can also be manufactured. Please feel free to contact us.

The gradient box (gradient-compatible drainage box) is a product that allows for the adjustment of the top edge to match the longitudinal gradient of the road. Are you struggling with the task of aligning the top edge of the box with the road surface for drainage on roads with longitudinal gradients or slopes? Our company can achieve the angle that matches the design gradient, eliminating the need for on-site fine adjustments or "chipping work." No two site conditions are the same. "Standard sizes won't fit," "special load conditions are required," "complex cutouts are needed," "precast for on-site casting. Custom solutions to shorten construction time"… Our custom-made solutions address these site challenges. With thorough quality control, we can flexibly accommodate special shapes and large products. We also welcome inquiries from the design stage. If you have any concerns, please feel free to contact us with just "one drawing."

■ High degree of freedom in shape and dimensions Special flat shapes (such as beveled cuts, notches, and arcs) that cannot be accommodated by standard products, as well as dimensional adjustments to suit site conditions, are possible. (There are tolerances for the products.) ■ Optimal rebar design Based on structural calculations according to the application (sidewalks, roadways, heavy loads, building foundations, etc.), we provide optimal rebar placement. We also flexibly accommodate reinforcement for openings and the embedding of hanging fixtures. ■ Shortened construction period and labor savings Since manufacturing and curing are completed in the factory before delivery, there is no need for formwork assembly, concrete pouring, or curing periods on-site. This significantly contributes to reducing the construction period and labor costs. ■ Excellent quality control Manufactured in a stable factory environment unaffected by weather, we deliver high-quality products that reliably ensure the design strength.

We want to install large products, but the delivery route is narrow, or a large crane cannot be set up. Our split products resolve this dilemma on site. Freedom of delivery: By splitting the product (when structurally feasible), transportation with small vehicles becomes possible. Strong integrity: Our unique "interlocking structure" ensures that after assembly, it performs at the same level as a single piece. Cost reduction: We minimize the costs of special vehicles and large machinery, optimizing the total cost.

This is a "hybrid handhole" installed in the tunnel's interior. It was realized from the voices of "concerns" at the site! 【Ensuring "ease of opening" and "durability" in harsh tunnel environments.】 The tunnel environment is humid, and there is a demand for "ease of inspection" due to vibrations from vehicle traffic and salt damage. We address these challenges. In the dark and high-humidity environment of the tunnel, the "sticking" and "corrosion" of the handhole cover can significantly hinder maintenance. Our handhole is compatible with a checker plate cover specification. It alleviates on-site stress and guarantees reliable access over the long term. ▪ Excellent rust prevention performance: We use checker plate made of hot-dip galvanized steel, which prevents corrosion from the unique humidity and water leaks in tunnels for an extended period. ▪ Reliable anti-slip and safety design: The raised checker pattern prevents slips and falls for pedestrians and workers. Additionally, it features a high-precision finish that minimizes the height difference with the concrete edge. ▪ Bolt fixation and dust-proof design: The bolt-fixed design reduces "play" caused by vibrations during vehicle passage. It prevents the intrusion of dust and mud, safely protecting the internal cables.

"Panel Foundation" covers a wider range of applications (such as control panels, power receiving panels, communication panels, etc.) than "Distribution Board Foundation." Control panels and power transformation equipment are the heart of a facility. The foundation that supports them requires a high level of reliability that does not allow for uneven settlement or deterioration. ▪ Trust in high-strength concrete: Through strict mix management and steam curing based on JIS standards, we have achieved a dense and robust structure that is difficult to realize with on-site pouring. ▪ Support for various panel sizes and loads: We propose optimal products based on load calculations, from small communication panels to large freestanding panels. ▪ Smart wiring management: The positions for entry and exit sleeves can be freely set. This secures internal wiring space and achieves a foundation with high maintenance accessibility.

We accept consultations at the drawing stage for everything from standard products to custom sizes. As a partner that supports the site from the foundation, please consider us for your needs. Fences, solar panels, streetlights... It is precisely for small-scale yet labor-intensive foundation work that secondary products come into play. In addition to a variety of size options, we can also accommodate specifications for anchor bolt and FEP embedding positions, as well as custom shapes.

Custom-made drainage boxes manufactured individually to match site conditions. They flexibly accommodate complex dimensions, opening shapes, internal partitions, and piping installations, ensuring both workability and durability.

The tanks are completed solely through crane installation and component joining, significantly shortening the construction period compared to on-site casting methods. This contributes to improved productivity in sites facing severe labor shortages. ● Uniform high quality through factory production Manufactured under strict quality control in JIS-certified factories. The components excel in dimensional accuracy and durability. (Note: there are allowable tolerances.) Safety is ensured through designs based on structural calculations against groundwater pressure and superimposed loads. ● Flexible response to various shapes and capacities Layouts such as L-shaped or polygonal can be configured to match the site shape. We propose products optimized for site conditions, ranging from small water tanks to deformed types.

In the cable duct (CCBOX), the junction box (special section) that serves as the "key" for branching and pulling in cables is located. The most complex process in the construction of the cable duct is concentrated in the "junction box." Our precast junction boxes combine strength to withstand harsh underground environments with smart workability that dramatically shortens construction time on site. They robustly support the urban power supply network from underground. We accept inquiries for custom manufacturing tailored to site conditions.

The underground utility duct (CCBOX) is an essential infrastructure for enhancing the urban landscape and strengthening disaster prevention functions. Among these, concrete secondary products designed for "power specifications" require strict quality standards and durability to safely and efficiently protect high-voltage cables. We manufacture reliable products that comply with the standards of power companies. ▪ We meet the strict delivery standards of each power company. ▪ Precasting improves efficiency in on-site work.

The opening and closing of the grating is easy. Furthermore, it is designed to prevent bouncing even when a vehicle is on it due to the locking mechanism. The main body has been lightweighted with knockouts. Processing on-site is also easy. As it is a standard product from our company, we have a large stock available. ※※ We have stock in increments of 100H from a height of 500H to 1200H. ※※

The pump pit is an important facility that supports the "infrastructure that must not stop," which involves the forced drainage of groundwater, rainwater, and wastewater. We prioritize "maintainability" and deliver precast products that do not require a curing period. Piping work and pump installation can be done immediately after installation, contributing to significant reductions in construction time. We also accept production in a two-part specification to accommodate delivery conditions.

This product is a concrete secondary product ideal for the entry and branching points of communication and electrical cables. Thanks to uniform quality control through factory production, it significantly reduces construction time compared to on-site casting. We can deliver it to the site with hole processing and pipe material installation according to your requirements.

Rolled gutters (integrated curbside drainage ditches) are particularly required to have the functions of "quickly draining rainwater from the roadway," "driving stability and safety when vehicles drive over them," and "aesthetic quality of construction." The drainage ditch located at the edge of the road is not just a drainage facility. Our rolled gutters create a safe and comfortable road space that does not compromise vehicle driving stability. ▪Significant reduction in construction time: No curing period is required after pouring. Since the paving process can begin immediately after installation, the lead time until road opening is dramatically compressed. ▪High strength and resistance to chipping: High-density concrete cured with steam in the factory. It is less likely to experience "corner chipping" during construction or when heavy machinery comes into contact, reducing the need for repairs.

By installing a dedicated clean flow wall inside the pit, we suppress turbulence and swirling flows caused by inflowing water. This helps to regulate the water flow near the pump's suction inlet, preventing air entrapment and vibrations. It reduces the load on the pump body and maintains a stable discharge volume. By manufacturing the clean flow wall as a precast product, we have achieved an ideal fluid environment without the need for complex formwork work on-site.

Separation tanks (oil traps, grease traps, sedimentation tanks, etc.) require internal partition plates (dividers), which can make them very heavy when designed as a single unit, posing challenges in sites with limited access. We design and manufacture products that balance the mobility of a "two-part" system with separation performance. They can be connected using flanges.

【Usage】 ▪ Road and parking lot drainage: For the collection and drainage planning in areas where vehicle passage is expected. ▪ Factory and facility exterior: For constructing drainage networks within sites where complex piping intersects. ~ "Opening" design that requires no on-site processing ~ Based on the design dimensions, openings for pipe connections are arranged during factory production. This eliminates the need for noisy and dusty chipping work on-site, significantly improving the safety and speed of construction. ~ "Drop cover type grating" that accommodates vehicle passage ~ Adopting a drop cover type that fits securely into the edge of the catch basin. This reduces rattling and allows for grating that can handle T-25 (large vehicle) loads. It achieves both drainage efficiency and safety during passage.

A concrete basin used to collect rainwater, temporarily store it, and allow it to permeate. Due to being a precast product, site restoration is quick. This leads to a reduction in construction time. It also reduces running costs. It can accommodate combinations of standard products. *There are also many ready-made and stocked products available. Custom sizes can be accommodated depending on the site. Please feel free to consult with us.

A large manhole that looks small compared to people! Due to construction on a residential road, early restoration is necessary! Since it is factory-manufactured, the quality is stable. "Convergence manholes, extra-large manholes, and catch basins" are essential for the construction of rainwater trunk lines. These large products are very difficult to install on-site (deep excavation, massive rebar, prolonged road occupation, etc.), so we propose "overwhelming construction time reduction and safety with large precast products." ▪ Overwhelming construction time reduction: The construction of large manholes that usually takes weeks can be shortened to just a few days. This accelerates the lifting of road restrictions and minimizes the burden on nearby residents. ▪ Significant improvement in safety: Long-term work in deep pits is unnecessary. This reduces the risk of collapse and falls, making on-site safety management easier. ▪ Cut excess costs on-site: You will be freed from securing formwork and rebar workers, as well as arranging concrete delivery trucks.

The header box is a "terminal for equipment," where piping for water supply, hot water supply, and air conditioning is concentrated. On-site construction requires significant effort for adjusting the position of pipe penetrations and waterproofing, making "high-precision opening processing" and "securing maintenance space" essential. The header section, where multiple pipes intersect complexly, can be resolved by precast products that alleviate the difficulties of positioning and sleeve installation on-site. It offers an overwhelming sense of speed, allowing the header to be installed on the same day it arrives, enabling immediate commencement of piping work. ▪ Free openings: Based on the piping diagrams, knockouts and sleeves are accurately placed in the factory. This reduces the cost and time of additional on-site work such as "core drilling" and "chipping." ▪ Excellent working space: The internal space is optimally designed. The smooth interior finish facilitates easy connection and insulation work for pipes, contributing to reduced fatigue for workers and improved construction quality. ▪ Same-day backfilling, immediate next steps: Since there is no need for a curing period, piping work inside the building and external structures can proceed along the shortest route.

We solve design challenges that cannot be addressed with off-the-shelf products, such as special gradients and inflows from multiple directions. We propose optimal structural designs that leverage years of expertise, including the flexible setting of opening positions, inverted processing of base plates, and accommodating special loads. ▪ Flexible customization: Enables 'free openings' tailored to the type, outer diameter, and angle of the pipes. ▪ Significant reduction in construction time: No need for formwork or rebar work on-site. Can be backfilled immediately after installation. ▪ Stable quality: Achieves high strength through factory management in accordance with JIS standards, unaffected by weather. ▪ Total cost reduction: Improved overall economy through reduced labor costs, material waste, and shorter curing periods. ▪ Rapid drawing response: Support for creating layout drawings and structural calculation documents during the planning stage.

In road maintenance and urban development, manhole frames are an important part that, while understated, significantly affect safety and durability. Our company provides high-quality manhole frames with special specifications, utilizing the technology cultivated through years of manufacturing concrete secondary products. ▪ Millimeter-level dimensional accuracy: Custom dimension design is possible to match the specifications of the grating and the site conditions. ▪ Shortened construction period: Complex formwork and concrete pouring on-site are unnecessary. Installation is completed simply by placing the product, directly addressing labor shortages and reducing construction time. ▪ High durability and high quality: With thorough quality control through factory production (compliant with JIS standards), we guarantee uniform strength and beautiful finishes that are difficult to achieve with on-site pouring. We accept all special shapes and small lots. Please consult us starting with just a single drawing.

Groundwater, humidity, and the many constraints of the underground environment. The "uniform quality" that is difficult to achieve on-site is delivered through factory-produced products under strict management. ▪ High Durability Concrete: The meticulous concrete produced in the factory exhibits high resistance to carbonation, salt damage, and groundwater. ▪ Accommodating Complex Shapes: We provide reliable customization tailored to design specifications, including knockout holes for cable entry, grating frames, and anti-slip processing.

By using precast concrete for the main components and steel materials for the connections and upper structures, we achieve unprecedented construction efficiency. "Large concrete manholes are too heavy for cranes to reach" and "opening processing on-site is difficult"... the hybrid manhole solves these on-site challenges. ▪ Amazing constructability: By making part of it steel (or composite materials), we reinforce the opening for waterway connections and enable "precastification"!

In recent years, with the intensification of heavy rain measures, sluice gates are essential for protecting regional safety. The foundation, or chamber, requires a robust structure that can withstand repeated water pressure loads and maintain long-term quality. The chambers for installing sluice gates (flap gates and slide gates) must have resistance to water pressure, precise installation holes, and excellent water-tightness. The risk of "on-site construction failures (such as misalignment of bolt positions)" is resolved through "precise integrated molding produced in the factory." ▪ Elimination of bolt position misalignment: Inserts are embedded in the factory according to gate specifications, completely eliminating the need for chemical anchor installation or rework due to positional misalignment on-site. ▪ Gate installation on the same day: There is no need to wait for the concrete curing period. The gate body can be installed immediately after setup, making it ideal for urgent construction ahead of the flood season. ▪ Highly water-tight integrated structure: The chamber body and installation surface are integrally molded in the factory. This reduces the risk of leakage from joints and provides reliable water-tight performance on-site. (There are also retrofit products available.)

The installation of the corner chamfer (gate board) requires the verticality and smoothness of the groove (guide) part to be perfect. In on-site construction, issues such as warping of wooden frames or distortion of the groove due to concrete slurry can lead to problems like boards not fitting or water leakage. However, with precast products, these concerns can be alleviated. ▪ Reducing repair work on the groove to nearly zero: Shaped using molds (such as wooden frames) by veteran craftsmen. This minimizes unnecessary rework such as chiseling and mortar repairs. ▪ Water stoppage possible on the day of delivery: No curing period required. Since the corner chamfer board can be set immediately after installation, it directly contributes to preparedness for sudden flooding and shortening of the construction process. ▪ Flexible opening and groove design: We can flexibly accommodate customization of three-sided or four-sided grooves, as well as depth and width, according to specifications.

The equipment room pit not only functions as a mere "box" to accommodate expensive equipment (such as pumps), but also places extreme importance on "maintainability." Our equipment room pit ensures the long-term safety of critical underground facilities through the meticulous concrete structure and reliable bonding unique to factory production. ▪ Excellent water tightness: High-strength concrete is used. ▪ Consideration for future maintainability: Efficiently secured internal wiring space and a smooth interior finish that facilitates inspection work. Adding or replacing cables is also smooth. ▪ Optimization of total costs: Long-lasting and high-quality precast products significantly reduce future repair risks, directly contributing to the reduction of the facility's life cycle cost (LCC).

Water level adjustment in fields and stopping water during cleaning. Would you like to make the daily harsh water management easier and more accurate? We significantly reduce the hassle of assembling formwork at sites that require complex shapes or the installation of stop walls. Our corner catch basins can be flexibly customized to fit the conditions of the site. Before thinking, "Is it impossible to do this on-site?" please consult with us once. ▪ Immediate delivery and installation: As a secondary product, there is no need for a curing period after installation. This greatly contributes to shortening the overall construction period and reducing labor costs. ▪ Flexible opening layout: We can accommodate hole processing according to pipe bottom height and diameter, as well as inflow and outflow from multiple directions with factory processing. ▪ Reliable quality assurance: Consistent production in a JIS-compliant factory. We provide strength and dimensional accuracy, which can vary in on-site casting, at the highest standards.

The underground utility duct (CCBOX) we offer is a concrete precast product designed to efficiently accommodate electrical wires underground. Compared to traditional on-site casting methods, precast products manufactured under strict quality control in factories boast overwhelming high strength and durability. As the need for efficiency in underground electrical wiring construction increases, our concrete precast products pursue design flexibility and workability on-site. ▪ Reduction of total costs: By enabling labor-saving on-site work, we adopt high-durability concrete that keeps maintenance costs low. ▪ Responding to diverse needs: We propose optimal solutions tailored to site conditions, including special shapes based on specifications from local governments, shallow burial compatible products, and information boxes. ◎ Improvement of landscape: By eliminating utility poles and wires, we create beautiful streetscapes with visible skies. ◎ Traffic safety: We widen the effective sidewalk width, allowing smooth passage for wheelchairs and strollers. ◎ Disaster preparedness: We prevent communication and power outages during earthquakes, protecting lifelines. ◎ Maintenance efficiency: The joint duct system allows for cable inspection and expansion without the need to excavate the road.

"The standard products do not fit," "There is not enough time for on-site casting"… Our custom-made technology solves such design dilemmas. Instead of adapting standard products to the site, we create products tailored to the site. ◎ Accommodating complex shapes and openings: Difficult shapes such as irregular manholes, angled cuts, and multi-directional openings are formed as a single unit in our factory. This avoids creating structural weaknesses and maintains high durability. ◎ Technical proposals from the drawing stage: For inquiries like "Can this shape maintain strength?" we offer optimal structural and reinforcement plans based on years of experience.
