Pipe Bursting in Esslingen

Esslingen municipal utilities have trenchlessly rehabilitated an old cast iron pipeline using the rehabilitated using burstlining. They were able to significantly reduce effort and costs compared to traditional rehabilitation methods. Due to the high requirements, they used the egeplast SLM® DCT pipe system with integrated quality inspection.

Trenchless Rehabilitation using the Pipe Bursting Method

For the rehabilitation of the parallel cast iron gas and drinking water pipelines, each with an outer diameter of 160 millimeters, Esslingen municipal utilities opted for trenchless rehabilitation using the pipe bursting method. The rehabilitation

Aging cast iron pipelines often entail significant effort and high costs. To minimize both, the installation of new pipelines using the burst lining method is recommended.

In trenchless rehabilitation of old pipes using the burst lining method, a plastic pipe is pulled into the existing pipeline. The old pipe is burst, and the fragments are displaced into the surrounding soil. The end result is a rehabilitated plastic pipeline with the same or a larger diameter than the previous old pipe. Since this special installation technique places particularly high demands on the pipe material due to the forces involved and the sometimes sharp-edged fragments of the burst material, egeplast expressly recommends the use of jacket pipes for this purpose. The Esslingen municipal utilities went one step further, opting for the egeplast SLM® DCT, a pipe system with integrated quality control for closed construction. Integrated conductor strips enable the pipe system to be tested for integrity immediately after installation. In this way, the security of supply can not only be restored relatively easily, but also documented beyond doubt. The Esslingen municipal utilities are very satisfied with the product.
