The technology of puncture by the double punching method has been developed.

The first pipe is fed into the pit and pressed into the ground to failure by a heavy bulldozer. Then a second pipe of smaller diameter is fed into the depressed pipe, which is also pressed by a bulldozer and filled with soil. After the second pipe is filled with soil, the bulldozer removes it from the first pipe and the collected soil is sent to the dump. After the formed bottomhole in the first pipe is cleared, further indentation of the pipe is performed. The cycle of indentation/clearing/indentation is repeated until the first pipe is in the receiving pit.
