Trenchless replacement and new installation of connecting pipes
Trenchless replacement and new installation of connecting pipes with hydraulic pulling units
Efficient pipe laying with compact pulling units and short set-up times
Compact and robust hydraulic pulling units with tensile and compressive forces of up to 200 kN are available for the trenchless replacement and laying of new gas and drinking water supply connection pipes. The proven systems require only very short set-up times. New pipes with an outer diameter of up to 110 mm and lengths of up to 25 m can be installed without any problems in displaceable soils.

Efficient solutions for trenchless pipe replacement and renewal
We have developed customized and efficient technical equipment for the following areas of application of trenchless replacement and new installation of connecting pipes:
hydros®BOY:
Replacement of connecting pipes made of rigid metallic materials. When using the press frame, the system can also be used for trenchless installation.
hydros®LEAD:
This innovative process, known in the literature as the internal pressure-supported winding process, is used especially for the complete replacement of lead drinking water connection pipes or flexible plastic pipes.
It goes without saying that our trenchless technologies for replacing and laying new connection pipes meet the requirements of DVGW GW 325 (A).
Incidentally, future maintenance and repair work can be carried out using standard tools and does not require any special attachments.
hydros®BOY: Replacing and laying new connection lines
hydros®LEAD: Replacing lead connection lines
The hydros®LEAD method, also known as the internal pressure-supported winding method, is used for the trenchless replacement of connecting pipes made of lead or flexible plastics, preferably with PE pipes. As a rule, only one excavation pit is required at the connection point of the supply line/connection line and, if necessary, a further excavation pit in front of the basement wall.
By using a special pulling hose developed for this task, which creates a positive and friction-locked connection between the lead pipe and the pulling element. This continuous transmission of force along the entire length of the replacement section allows the lead pipe to be removed from the ground by means of axial tensile forces. Even socket joints and other repair points (e.g. material transition to PE) do not affect the replacement process.
A specially developed hydraulic pulling device was also produced for this purpose. The use of this keyhole technology guarantees a particularly economical success, as it considerably reduces the installation effort and only a very small section of the supply line is required.
