2.2 km of DN 3000 reinforced-concrete jacking pipes for new sewers

摘要

Increasing sealing of surfaces in particular in large cities and the more frequent occurrence of heavy-rain events result in considerable quantities of sewage that overload the sewer systems. The decision was made for the construction project "Sewer rehabilitation Landsberger Strasse" to achieve a significant improvement of the hydraulic situation in the sewer network in the west of Munich. The objective was to relieve the existing and often overloaded sewer system in the area of Pasing and Laim and to divert better and more effectively the critical flows of combined wastewater in the east and/ or west of Munich by a new sewer 3 m in diameter. The first partial construction section in the area of "Offenbachstrasse" up to "Am Knie," as well as part of "Laimer Kreisel," was already successfully completed in 2016. Next followed the second construction section "Landsberger Strasse." The successful completion had closed the gap between the two preceding construction measures. The contract for the extensive works had been awarded by the Munich drainage service Muenchner Stadtentwaesserung, which had also been in charge of planning and implementing the construction project. Muenchner Stadtentwaesserung is also responsible for regular maintenance and surveillance of the public sewer system, so that its experience and knowhow could be considered in planning the project.
