Micro Pipebursting
Replacement of underground pipes, non dig technology
Micro Pipebursting
Trenchless Pipeline Laying (TPL)
How it works
Two vertical shafts are prepared – one for the pipebursting unit, and one for inserting the new replacement pipe.
By hydraulic force, solid steel rods are pushed, one by one, up through the existing pipeline. Upon arrival at the second vertical shaft, the solid steel rods are connected to the bursting head and new replacement pipe. Due to the limited space, the new replacement pipe is normally a modular pipe.
Thereafter the pipeburster will pull the bursting head into the existing pipeline. The existing pipeline is split and pushed into the surrounding soil, and simultaneously replaced by the new replacement pipe.
When the bursting head arrives at the first vertical shaft, the job is completed.
