What is the municipal pipeline micro-pipe jacking construction method

Q: What is the micro-pipe jacking method for municipal pipelines?

A: The micro-pipe jacking method for municipal pipelines is a type of mechanical pipe jacking method. Pipe jacking is performed in a pre-drilled working well using an auger, a small-diameter micro-pipe jacking head, and a mud-discharging pipe device. This method allows for a single-step horizontal penetration of the pipeline, while minimizing footprint and environmental impact. 

It is primarily designed for municipal underground pipelines with diameters between DN300 and DN800. effectively overcoming the limitations of traditional pipe jacking methods on municipal pipeline diameters.
