Introduction to Horizontal Directional Drilling Technology

Advantages of Trenchless Horizontal Directional Drilling Technology：

1.Horizontal Directional Drilling Trenchless Technology can reduce the damage and adverse effects on the environment, traffic, neighboring buildings, reduce noise and dust type pollution, and will not affect normal commercial activities and life.

2.Horizontal Directional Drilling Trenchless Technology can be used to lay pipelines in occasions where traditional excavation methods cannot be constructed, such as crossing rivers, highways, railroads, monument protection zones and so on.

3.Horizontal Directional Drilling Trenchless Technology has better economic benefits. There are fewer construction constraints and the optimal construction path and depth of the buried pipe can be selected.

4.Horizontal Directional Drilling non-excavation construction is not limited by the season, covers a small area, and is subject to site restrictions;

5.Horizontal Directional Drilling non-excavation construction is highly flexible, fast and with fewer person.

Origin of Horizontal Directional Drilling Trenchless technology：

Horizontal Directional Drilling Trenchless Technology originated from the oil drilling industry and was first born in the United States in 1971. China introduced the technology in the mid-1980s and began to develop rapidly after the 1990s. It was firstly applied in the field of urban pipeline network construction and transformation, and gradually developed into the main technical means of non-excavation construction for long-distance large-diameter oil and gas pipelines.

Horizontal Directional Drilling Trenchless Technology Application Areas：

The purpose of Horizontal Directional Drilling Technology is to lay pipelines directly underground without excavating the ground, and it is usually used when there are local obstacles on the surface or underground that are not suitable for excavation.

It is a non-excavation pipe-laying technology used when there are local obstacles on the ground surface or underground which are not suitable for excavation. At present, the main objects of crossing construction with this technology are: rivers, highways, mountains, streets and important or non-demolishable buildings.

Horizontal Directional Drilling Trenchless Technology Construction Principes：

1.The trajectory formed by Horizontal Directional Drilling is usually a curve as a whole, and the curve can be divided into three sections, which are: the inward sloping section (curve section), the horizontal section (straight line), and the outward sloping section (curve section).

2.Horizontal Directional Drilling process is more suitable for laying flexible pipes (PE pipe, HDPE, steel pipe), especially suitable for laying with small pipe diameter and long distance pipes.

3.The bending of the trajectory curve is limited, depending on the bending performance of the drill pipe and the pipe, usually, steel pipe＜drill pipe＜PE pipe.

Horizontal Directional Drilling Construction Soil Type:

Horizontal Directional Drilling technology is mainly applied to the stable and homogeneous stratum such as silt, clay, dense fine sand, etc. It can also be used in rocky stratum.

and also can be used in rocky strata, but it is very difficult to use horizontal directional drilling technology in pebble gravel and backfill layers.

However, it is very difficult to drill in pebble gravel and backfill layers, so it is not recommended to use horizontal directional drilling technology to drill in pebble gravel and backfill layers.
