Construction Characteristics of Horizontal Directional Drilling

1. Directional drilling construction will not hinder traffic, will not destroy green space and vegetation, and will not affect the normal life and work order of shops, hospitals, schools and residents. It solves the interference of traditional excavation construction on residents' life, traffic and environment, and the damage and adverse effects on the surrounding building foundation.

2. Modern crossing equipment has high crossing precision and is easy to adjust laying direction and burial depth. The arc laying distance of the pipeline is long, which can fully meet the design requirements of the buried depth and allow the pipeline to bypass the underground obstacles.

3 The buried depth of urban pipe network is generally less than 3 meters. When crossing the river, the buried depth is generally 9-18 meters below the riverbed. Therefore, horizontal directional drilling rig is adopted for crossing, which has no impact on the surrounding environment, does not damage the landform and environment, and meets various environmental protection requirements. requirements.

4. When horizontal directional drilling rig is used for crossing construction, there is no water on or under water operation, which will not affect river navigation, and will not damage the dam and riverbed structure on both sides of the river. The construction is not limited by seasons, the construction period is short, the personnel are few, and the success rate is high. The construction is safe and reliable. Features.

5 Compared with other construction methods, the speed of entering and leaving the site is fast, and the construction site can be flexibly adjusted. Especially in urban construction, it can fully demonstrate its advantages, and the construction area is small, the project cost is low, and the construction speed is fast.

6 When the river crosses, because the pipeline is buried 9-18 meters underground, there is little underground oxygen and other corrosive substances, so it plays the role of natural anti-corrosion and heat preservation, which can ensure that the pipeline runs longer.
