The difference between ordinary jacking pipe and micro jacking pipe

The Difference Between Regular Pipe Jacking and Micro Pipe Jacking

The differences between regular pipe jacking and micro pipe jacking are as follows: Micro pipe jacking has a very small diameter, making it inaccessible to humans. Its diameter is typically under 400mm, with diameters as small as 75mm. These pipes are typically buried very shallowly, sometimes traversing complex soil layers. This has become a new branch of pipe jacking construction, with rapid technological development and constant innovation in its form. There are significant differences between micro pipe jacking and pipe jacking. First, the principles of micro pipe jacking and pipe jacking are different. Generally, micro pipe jacking uses small-diameter pipes, which allows for relatively easy construction conditions and occupies a smaller area. Pipe jacking, on the other hand, generally involves more challenging construction conditions and requires the thrust between the main jacking cylinder and the pipe.

Second, the technologies used by micro pipe jacking and pipe jacking differ. Micro pipe jacking requires traction, while pipe jacking is a trenchless construction method with higher technical requirements.

Micro pipe jacking for municipal pipelines is a type of mechanical pipe jacking. 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 system achieves a single-step horizontal penetration of the pipeline while minimizing footprint and environmental impact. Primarily targeting municipal underground pipelines with diameters between DN300 and DN800. it effectively overcomes the limitations of traditional pipe jacking methods on municipal pipeline diameters.
