Renewal of sewers in densely populated urban areas is often difficult, due to the limited space, the traffic situation and the large number of existing utilities. The TAUBER MiniTunnel system with concrete or polymer concrete tubing has proven its worth here.
The tubbings are tube segments of 60 and 75 cm length, respectively. By means of an axially formed tongue and groove, three identical segments form a stable pipe ring. The required tubing can be produced in prefabricated concrete sections or semi-automatically on site.
Our process is suitable as protective pipe for supply pipes, for sewage pipes, for district heating pipes or as a product line. The network connection of existing house connections is capped during propulsion, auxiliary cables take over the current final supply and after completion, the connections are integrated into the new tunnel tube.
The MiniTunnel system has been successfully used for sewer rehabilitation with different requirements. It allows, in addition to the new construction and renovation, also overpassing old channels and creating a new canal terrace.
Our MiniTunnel system also includes the construction of canal shaft constructions, canal points and collectors. Realizations of GRP (glass fibre reinforced plastic), precast concrete parts or linings of existing shaft constructions with polymer concrete slabs are used.
