Advantages And Application Scope Of Horizontal Directional Drilling Construction!

（1） Advantages of horizontal directional drilling

1. When directional drilling is used for crossing construction, the above ground function can be used normally. For example, when crossing roads and railways, the traffic may not be blocked; When crossing the river, it can ensure that the river is unblocked without blocking navigation and flood drainage.

2. Due to the non excavation construction, the excavation, transportation and stacking of a large amount of engineering soil are reduced, which is conducive to environmental protection. At the same time, it also correspondingly reduces the cost of foundation embedding and ground restoration.

3. The construction period is short, the operation is safe and rapid, the comprehensive cost is low, and the social benefits are significant. When the excavation construction cannot be carried out or is not allowed, the directional drill can be used to cross under it. Today, with the rapid development of urban construction, avoiding the road zipper project caused by repeated excavation and repair has high social and economic benefits.

（2） Application scope of horizontal directional drilling construction

Horizontal directional drilling is suitable for pipeline crossing projects in urban roads, highways, railways, rivers and other sections that are not suitable for heavy excavation construction. It can be used to lay various underground pipelines such as natural gas, heat, tap water, rainwater and sewage, electricity, telecommunications, cable television, network, etc. the pipes can be mainly divided into steel pipes, PE pipes, aluminum plastic pipes, copper plastic pipes, cables, optical cables, etc.
