Introduction to the small-diameter pipe reconstruction method "Bursting Method"

Introduction to the small-diameter pipe reconstruction method "Bursting Method"

A trenchless technology method that allows for the installation of new pipes without digging the ground.

Our association handles a non-excavation technology called "bursting method," which allows for the installation of new pipes without digging into the ground, addressing aging infrastructure. This technique is environmentally friendly and allows for speedy construction, recognized globally as a standard method that was not achievable with traditional excavation methods. 【Features】 ■ Reduced construction time ■ Ensured safety ■ Environmental protection *For more details, please download the PDF or contact us.

HDD Method (Guided Horizontal Drilling) / TerraJet: Solving Labor Shortages!

HDD Method (Guided Horizontal Drilling) / TerraJet: Solving Labor Shortages!

Piping and wiring burial system! Numerous achievements! Improving work efficiency in lifeline construction! "Challenging the creation of lifelines that traverse the Earth and underground."

With the acceleration and advancement of urban functions, the development of various lifelines such as water supply and drainage, electricity, gas, and communication is becoming increasingly important. The HDD method (Horizontal Directional Drilling) / TerraJet is a construction method for burying pipes and cables using non-excavation techniques, which reduces traffic disruption and soil disposal issues. It allows for clean and safe construction by detecting the construction position from above ground while advancing. In recent years, disasters have become more severe, and from the perspective of improving disaster prevention, the replacement of aging pipes and the transition to earthquake-resistant pipes are being promoted. The HDD method / TerraJet is gaining attention as a method for burying water supply and drainage pipes and gas pipes underground. In Europe and the United States, it is known by names such as NO-DIG, Trenchless, HDD (Horizontal Directional Drilling), no-dig, trenchless, and horizontal directional drilling. 【Features】 - Flexibility and adaptability - Shortened construction period - Economically low cost - Harmony with the natural environment - Safety For more details, please contact us or download the catalog.

Non-excavation method "Advancement method"

Non-excavation method "Advancement method"

It can be utilized not only in sewers but also in gas, water supply, agriculture and water resources, electricity, communications, etc.

The "pushing construction method" involves attaching a tunneling machine to the tip of a push pipe (mainly reinforced concrete pipes) and excavating underground while literally pushing the pipe forward with hydraulic jacks from the rear to install it. This method can accommodate a wide range of pipe diameters, from large-diameter to small-diameter pipes, and can handle various soil conditions, from soft ground to gravel and bedrock layers. [Types of Pushing Construction Methods] ■ Large and medium diameter pipe pushing method (open type / closed type) ■ Small diameter pipe pushing method (high load-bearing method / low load-bearing method / steel casing pipe method) ■ Special pushing methods (box culvert pushing method / de-slipping curtain method) *For more details, please download the PDF or feel free to contact us.

COMPASS Method (Ground Cutting and Box-Type Pushing)

COMPASS Method (Ground Cutting and Box-Type Pushing)

Non-excavation methods for constructing small cross-section structures.

The COMPASS Method TYPE 3 (Ground Cutting and Box Tunneling) is a non-excavation method used for the construction of small cross-sectional structures such as rivers and sidewalks that cross under roads and railways. To insert the roof of the cutting head into the cutting groove (the space created by the ground cutting wire scraping the ground) in front of the cutting head body, it is possible to prevent excessive soil intake and the uplift of obstacles caused by the cutting head, thereby minimizing the impact on the ground above. 【Features】 ■ Safety ■ Workability ■ Cost-effectiveness *For more details, please refer to the PDF materials or feel free to contact us.
