Envi-liner method
The construction extension has reached a total of 4,930 km, boasting a high track record with the same type of advancement method.
This technology is a non-excavation small-diameter pipe jacking method that can construct various types of pipes ranging from φ150 to φ1000. Using a jacking machine installed in the launch shaft, the buried pipes are sequentially laid towards the receiving shaft, eliminating the need to excavate the road surface. Additionally, the jacking device is designed to be compact, allowing for launching from small shafts. Since it uses an excavation and soil removal method, there is no need for large surface facilities like those required for slurry methods, and the equipment associated with the work, such as cranes and generators, can be kept small, contributing to overall cost reduction. 【Features】 ■ Capable of constructing various types of pipes from φ150 to φ1000 ■ Non-excavation construction ■ Suitable for difficult ground conditions ■ Small space and low cost ■ No need to excavate the road surface *For more details, please refer to the PDF document or feel free to contact us.
