Expansion of utility tunnel for replacement building
With a total construction budget of €800 million, this major renovation project for the 40-year-old main building at the University of Bielefeld involved a comprehensive package of measures. A replacement building was erected to ensure that the university could continue to operate despite the extensive renovation work. The departments affected by the renovation moved into this building, where they were able to continue teaching.
During the new construction of the replacement building, an existing utility tunnel was expanded. An expansion concept had to be developed and implemented for the piping systems installed there.
Construction volume: €800 million
Building type: University
Requirements: Expansion concept
High-grade MÜPRO fixing technology was used for the expansion of a utility tunnel:
- Pipeline expansion point with 1 degree of flexibility for expansion compensators for plant construction/heavy-duty pipe fixings in a hot-dip galvanised design
- Pipe slides type TP-1 with lateral guide and lift lock via MPT-guide. The supporting structure was built using MPT-Q100 support sections. The MÜPRO application engineers also calculated the expected forces and supplied the necessary structural analyses.
- Fixed anchor point for pipelines in hot-dip galvanised form. STATO bracket sets installed in series means that the installation can withstand loads of up to 16.5 kN per set.
- The pipeline expansion point with 2 degrees of flexibility is used to absorb changes in length in the corner section of L expanders. The structure consists of a green Junior DÄMMGULAST single bossed clamp for reducing noise levels to 18 dB(A) and a 1.75 kN slide guide in a flat design fitted in a cross connection. Fastening to the wall is carried out using an MPC wall hanger bracket
