The Bell method is a "world-first system" that significantly reduces maintenance costs for sewer pipes and contributes to their longevity. 【Features】 1. Long-distance thrust Unlike conventional methods, the allowable thrust length is not limited by the pipe's allowable load capacity, allowing for long-distance thrust of up to 250 meters even with low-load capacity pipes. 2. Curved thrust The tunneling machine is equipped with two directional correction devices, enabling multiple curved thrusts of up to 60R. 3. Response to obstacles If unexpected obstacles are encountered during tunneling, it is possible to retreat and proceed with a detour alignment. 4. Shortened construction period By adopting an autonomous measurement robot for in-pipe surveying, there is no decrease in daily progress due to the number of curves or curvature radius. Additionally, using the Bell method thrust pipe (1.33m pipe) reduces setup changes by 33% compared to 1m pipes, enhancing work efficiency. 5. Longevity Long-distance and curved thrust is achieved with durable and earthquake-resistant PVC pipes, contributing to the longevity of sewer pipes. 6. Earthquake resistance High earthquake-resistant SUS color is used. The joint section of the thrust pipe maintains water tightness up to an angle of 3 degrees, preventing water and soil from entering.

The "PIT Method" is a vibration-free, low-noise, and environmentally friendly method for constructing shafts. Using the oscillating press-in type shaft construction machine PC1500 to PC3000, a dedicated steel casing (cylinder) is pressed into the ground while oscillating. After excavating within the retained (temporary structure) steel casing to the specified depth, a concrete base is poured, and after water replacement, it is constructed as a shaft. It can also be used for removing obstacles during advancement, installing manholes, and renovating existing manholes. 【Features】 ■ Excellent safety ■ Superior workability ■ Outstanding operability ■ High precision finish For more details, please feel free to contact us.

The hard rock construction method is a technique that uses a horizontal boring single-pipe propulsion system, incorporating large and small down-the-hole hammers into the leading body, allowing for the crushing of hard soil types such as soft rock, hard rock, gravel, and cobblestones while being propelled with low thrust. After the completion of the steel pipe propulsion, it can accommodate various pipelines (such as water supply and drainage, electricity, gas, and other lifeline pipelines). Additionally, as a special method, it is possible to construct pipelines with a nominal diameter of 800mm or more using a reaming method that utilizes the reach.

The "Well Point Method" involves attaching a well point (a water intake device with a strainer) to the end of a pipe, injecting jet water, and driving numerous points into the ground to create a small well curtain, which is then connected to a central pipe for powerful suction by a pump, thereby lowering the groundwater level. This method allows for the simplification of earth retention work due to reduced water pressure and soil pressure from dry work, enhancing safety, shortening construction time, and ultimately reducing construction costs. Groundwater recharge methods (recharge wells) are also possible. 【Features】 ■ Lowering of groundwater level ■ Increase in soil shear strength - Excavation: Stabilization of embankment slopes and reinforcement of the excavation base ■ Increase in effective pressure due to consolidation: Increase in ground strength from reduced buoyancy For more details, please feel free to contact us.

Zypex is a concrete modification material that densifies the structure by promoting the growth of cement crystals in defects such as voids and cracks within the concrete, thereby blocking deterioration factors like water and enhancing waterproof performance to improve the durability of the structure. ■Mechanism of Concrete Densification■ The mechanism of densification by Zypex involves mixing concentrated powder with a specified amount of clean water to create a paste, which is then applied or sprayed onto the surface of the concrete. This allows catalytic compounds to penetrate deep into the concrete, promoting the growth of new cement crystals at the capillary voids and crack interfaces, thereby densifying the concrete structure itself. The depth of modification through crystallization can vary depending on the concrete conditions, but it can extend to over 30 cm in a moist environment.

The "Deep Well Method" involves installing a deep well inside or outside the main excavation trench and lowering the groundwater level in the surrounding ground by draining the groundwater that flows into the well using a submersible pump. This drainage method is effective when the permeability of the ground is high or when a significant drop in the water level is required. For more details, please feel free to contact us.

The "RBP Wall Method" is a slope construction technique that involves excavating the ground from the top of the slope while securing the slope with reverse bolt panels as it is lowered. By combining reverse bolt paneling with rebar insertion, it prevents collapse through the stabilization of cut slopes and the surrounding ground. This method is applicable for road widening, land development, steep slope countermeasures, fall prevention measures, and slope stabilization in areas with small ground stress, limited space, or adjacent to structures. [NETIS Number: QS-160035-A] **Features** - Can be extended in either vertical direction - Always ensures slope stability - Allows excavation on steep slopes even in areas with low ground strength - Has significant resistance to ground behavior during earthquakes and other events *For detailed features, application examples, and construction procedures, please download the PDF of the "RBP Wall Method" technical documentation.*

The "Mini Wall Method" is a construction technique that creates a soil-cement underground continuous wall with high water-stopping properties and uniform strength in the vertical direction by mixing and agitating cement slurry discharged from the base ground and the bottom end of the post using a chainsaw-type cutter mounted on a cutter post. Since uniform thickness walls can be created, it is possible to install core materials at arbitrary intervals, allowing for greater flexibility in soil retention design and the construction of economical soil-retaining water-stopping continuous walls. ■ We are currently offering a catalog summarizing basic knowledge and a collection of construction examples as a gift! 【Features of the Mini Wall Method】 ■ Due to the uniform thickness of the wall, the installation interval of the stress core material can be set arbitrarily. ■ Wall thickness can be adjusted by changing the cutter bits. ■ Construction close to structures and at property boundaries is possible. ■ The use of a suspended leader allows for step construction (5-6 m). * Please refer to the PDF data of the catalog and construction examples of the "Mini Wall Method" available for download.
