Method for installing pipes, involves immersing loose gravel with bentonite suspension, filling slit-pit with bentonite suspension, inserting pipe with pressing system, and starting clock pulse

摘要

The method involves inserting a pipe (15) from a pressing pit (1) with a hydraulic pressing system (3) into an advanced-slit pit (6). A destination board (12) is arranged at distance from a front side of a precursor pipe (2) with a knuckle formation (8) via the pipe. The destination board is pressed into the surrounding ground. The precursor pipe is filled with loose gravel (16), and the loose gravel is immersed with bentonite suspension (17), and the slit-pit is filled with the bentonite suspension. Another pipe is inserted with the pressing system, and a clock pulse is started. An independent claim is also included for a device for installing pipes.
