Overwhelmingly fast construction! Reconstructing and extending the lifespan of concrete corrosion caused by hydrogen sulfide and aging manholes using FRP rehabilitation materials that allow for adjustable wall thickness.
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!"
Leave the construction of long-distance and sharp curves in small-diameter tunneling to the jet method! 《Presenting a collection of construction achievements!》
Faster and safer! Solving challenges in sewer pipe rehabilitation work and contributing to improved work efficiency and quality!
Reinforcement that ensures safety against underground cavities and aging sewer pipes! We provide construction methods adapted to various site needs.
Rehabilitation of all types of pipes, such as circular, rectangular, and horseshoe-shaped, as a strong composite pipe integrated with existing pipes and rehabilitation pipe backfill material, while maintaining non-excavation and water flow!
A construction method that is friendly to cities and people, which involves crushing and expanding old pipes while pushing in new pipes of the same diameter or one size larger, all without excavation and without generating waste.
By using a specially developed machine to cut shallow grooves into the construction diameter, we eliminate the occurrence of shear marks and steps. Steps not only cause traffic disruptions but also contribute to noise.
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."
A leading conductor with a wide range of soil adaptability and high torque performance! Construction in a small shaft for a wide variety of ground conditions!
Systematization from excavation to soil removal and solidification treatment! Construction is possible from clay to boulder layers and hard soil!
A suitable bottom plate length can be selected for various design conditions such as gravelly soil, sandy soil, and clayey soil, and it can also accommodate other special conditions!
