Characteristics of horizontal directional drilling construction
1.1 The directional drilling crossing construction will not hinder traffic, destroy green space, 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 ’lives and traffic. Environment, surrounding building foundation damage and adverse effects.
1.2 The modern traversing equipment has high traversing accuracy, easy to adjust the laying direction and burial depth, and the long arc-laying distance of the pipeline can fully meet the design requirements of the burial depth, and can make the pipeline bypass the underground obstacles.
1.3 The buried depth of the urban pipeline network is generally less than three meters. When crossing the river, the buried depth is generally 9-18 meters below the river bed. Therefore, horizontal directional drilling rigs are used for crossing, which has no impact on the surrounding environment, does not damage the landform and environment, and adapts to environmental protection Items.
1.4 When the horizontal directional drilling rig is used for construction, there is no water or underwater operation, it will not affect the navigation of the river, and it will not damage the dams and river bed structures on both sides of the river. Features.
1.5 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 superiority, and the construction area is small. The project cost is low and the construction speed is fast.
1.6 When a large river crosses, because the pipeline is buried 9-18 meters below the stratum, there is little oxygen and other corrosive substances in the stratum, so it plays the role of natural anti-corrosion and thermal insulation, which can ensure the pipeline runs longer.
