Trenchless technology is classified according to construction technology
Trenchless technology can be divided into: directional drilling pipe laying technology, escape shuttle pipe laying technology, pipe jacking tunneling and laying technology, pipe jacking pipe laying technology.
Among them, the advantages of the directional drilling pipe laying technology are: the use of directional instrument guidance, the combination of directional detection and pipeline detection, can effectively adjust the drill bit, avoid pipelines, and is suitable for construction under complex formation conditions;
The pipe laying has a wide range of diameters, lengths and materials, suitable for pipe diameters below 1000mm, mainly using PE pipe laying and steel pipe laying; low interference to the surface, fast construction speed, high construction accuracy, is the fastest growing type of trenchless construction law. And because the underground pipe network in the urban area is relatively complicated, we mostly adopt the directional drilling pipe laying method when we conduct trenchless construction.
