The "Hume Pipe Pushing Method" is a pushing method that allows direct access to an existing manhole shield when the target shaft cannot be excavated or is undesirable to excavate. The excavation machine's outer shell is made of CPC steel pipe (Chemical Prestressed Concrete Steel Pipe), and the necessary driving equipment for excavation is incorporated in a recoverable state. After reaching the target, only the built-in equipment of the excavation machine is recovered, while the outer shell remains as a pipe (structure). 【Features】 ■ No need for construction costs for the target shaft and cutting edge excavation work ■ Cost reduction ■ Environmental protection ■ Avoidance of total loss of the excavation machine For more details, please feel free to contact us.

The "CMT (Compound Mini Tunnel) method" is not a single system method, but a general term for a system that responds to various construction conditions. There are "CMT ultra-long-distance propulsion system," "CMT floating system," "CMT rock propulsion system," "CMT cobble and gravel ground propulsion system," "CMT face obstruction removal propulsion system," and "CMT ultra-soft and quicksand ground propulsion system." *For more details, please refer to the catalog or feel free to contact us.*

The "SS Small Method," which has an overcutting function, rapidly mixes high-concentration mud water containing a large amount of excavated soil and clogging material sprayed onto the face in a chamber, creating a thick, high-concentration stable liquid. By pressurizing and filling the face and tail voids, this method achieves high stability of the face and is based on the concept of "stabilizing liquid methods" such as underground continuous soil retaining wall methods and reverse circulation methods.

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 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.
