At the construction site, the pipe well is the place where the “snail shell” is used as a dojo in the project.

In a narrow space, various specialized pipelines are arranged in a staggered manner, and workers need to weld, fix, and level each pipeline one by one in the well.

The pre embedding of casing should be closely monitored during structural construction, and a few centimeters away will require later chiseling; Pipeline fights are common, and repeated adjustments have become commonplace – traditional pipe well construction is essentially a “manual labor”.
