Work from a manhole usually becomes necessary when dirty water and sewer pipes are newly installed or when a collapsed sewer demands renewal, as shown in the example. First of all, the pipe line is established with a GRUNDOPIT. Then the pipe was renewed with the manhole pipe bursting machine.

Application example:
Total collapse of a storm water sewer beneath a building
Old pipe: concrete ND 300
New pipe: PP-HM, OD 280 x 18.0 mm
Replacement length: 30 m

Schematic illustration
