The renewal of sewers in closely built-up city areas can often be very
difficult due to limited space, traffic and a large number of existing
supply lines. In these situations the TAUBER Tunnel System with tubing’s
of concrete or polycrete proves to be very worthwhile.
The tubing are pipe segments of concrete, grade B 45 (DIN 1045), in a length of 60
and/or 75 cm. Three identical segments are combined to a solid pipe ring by means
of the axially integrated groove and tongue. The required tubing can be manufactured
at concrete pre-casting factories or they can be locally manufactured in a semiautomatic
process. The TAUBER Tunnel System can be used as a protective piping for supply lines,
as a sewer, for district heating lines or as a product line. House service connections
are temporarily separated from the mains while the driving work takes place and auxiliary
lines take over the current drainage. After completion of the work the connections are
incorporated in the new tunnel pipe.
