【NETIS Registration】Collects water leakage from the expansion device and drains it with a flexible drainage pipe.
The "Totaku Simple Drainage Device" for bridge expansion joints collects water leakage from the expansion device using a simple drainage system and drains it through a separately sold flexible drainage pipe (TAC Bridge Pipe), thereby improving the environment where steel materials such as bridge girders and bearings are prone to corrosion. Since construction is carried out from below the bridge without working on the bridge deck, traffic restrictions on the bridge deck are unnecessary, which shortens the construction period and enhances safety. 【Features】 - Does not require primer treatment or adhesive work - Fast construction - No special tools or work required - Easy maintenance - Lightweight and resistant to cold, made of polyethylene 【NETIS Registration: KT-100033-A】 For more details, please contact us or download the catalog.

Additionally, we offer a wide variety of options, allowing you to select basins that suit your specific needs. 【Product Lineup】 ■ AS Basin (for variable drainage ditches): Standard type / Plate type ■ PU Basin (for PU-3 drainage ditches): Standard type / Plate type *For more details, please download the PDF or feel free to contact us.
The finish is neat, and the inside is a solid large-diameter gutter!
The "Sukkiri Shimasu" is a catch basin that achieves a neat finish by reducing the size of the upper opening while increasing the effective internal cross-section. Since it has the same total width as road reinforced concrete ditches, there is no protrusion of the basin. Additionally, it can also be manufactured with a sinking prevention base. 【Features】 ■ Compact and neat ■ No protrusion at the corners, ensuring safe and smooth passage ■ Significant cost reduction possible *For more details, please download the PDF or feel free to contact us.

A catch basin that is easy to install, construct, and process on-site.
The "FCS drainage basin" is designed to pursue high quality, lightweight, and large capacity by reducing wall thickness while ensuring structural strength, making it suitable for changing site environments. By eliminating the corners on the inside at four locations, it is less likely to accumulate debris, making cleaning and management easier. Additionally, there are markings for joints (in 50mm increments) on the inner wall, facilitating the pouring of invert concrete. 【Features】 ■ Cost reduction in labor expenses ■ Lightweight and easy to transport and install ■ Reliable and stable strength, high quality ■ No worries about delivery times *For more details, please download the PDF or feel free to contact us.
Transform that "impassable" into "solution." Achieve split delivery "split and interlocking products" for narrow sites and difficult-to-access locations.
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.
Goodbye to the "distortion" and "chipping" of the groove. Factory-quality assurance with a smooth corner rounding.
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.
