Advancement construction method
Advancement construction method
We are engaged in construction using various methods such as the "Hume pipe jacking method," which incorporates a tunneling machine shell made of CPC steel pipes and includes recoverable driving equipment necessary for tunneling; the "CMT method"; and the "SS small method" for large and medium diameter pipe jacking. Additionally, we employ the "Cobra method," which allows for construction in rock and gravel layers using small diameter jacking, and the "Bell method," which enables long-distance and curved jacking using PVC pipes.
