Pipe-driving cone for steel pipes Ø90 mm–Ø190 mm for the MAX K95S

Pipe-driving sockets serve as an intermediate component between the pipe-jacking machine and the pipe being driven. Their function is to transfer the impact energy generated by the jack/hammer to the pipe being driven. The size of the machine and the resulting impact energy determine the maximum pipe diameter that can be driven using a given pipe-jacking machine. The most popular model, the MAX K130S, can install steel pipes with a diameter of up to 323 mm. The MAX K180S can drive pipes with a diameter of 406 mm, while the T240 hammer allows for driving pipes up to 711 mm in diameter.

For each jacking machine, a sleeve or set of sleeves is installed on the mole head, and then the entire assembly is inserted all the way into the end of the pipe being driven. Additionally, lugs made from a steel rod should be welded to the end of the pipe to allow the pipe being driven to be secured to the pipe-jacking machine with straps.

It is also a good idea to reinforce the end of the pipe by welding a ring made of steel rod to the outside, in order to increase the diameter of the hole created by the driven pipe. This will ensure that the driven pipe encounters significantly less frictional resistance from the soil. Additionally, it is also advisable to weld a similar ring to the inside of the pipe at its beginning. This will facilitate the subsequent removal of excavated material from the driven pipe using blow-out plates.
