Developed a siphon drainage system that allows for zero fuel costs and can be manually transported to prevent water level decline and dam failure! Drainage using the principle of siphoning can be easily activated!

Piping and wiring underground installation system (non-excavation and thrust method)! Numerous achievements! Also gaining attention for "overhead line removal"! "Challenging the creation of lifelines that traverse the Earth and underground."

Significantly improve the profitability of greenhouse cultivation.

Piping and wiring burial system! Avoid obstacles with vertical and horizontal curves! Reduce total costs! "Challenging the creation of lifelines that run through the Earth and underground!"

[Nigata Prefecture Agency] Standard construction distance of 100-150m/day! Due to the impact method using a breaker, it can handle hard ground!

A maintenance walkway is incorporated inside the trough, allowing for thorough maintenance by workers! Simple assembly of components enables installation by regular workers!

It has been 20 years since we started repairing rivers, waterways, bridges, and tunnels. As a subcontractor, we have managed and executed many construction projects. We will provide an estimate.
