The horizontal directional drilling rig is used for crossing construction. There is no water and underwater operation, which will not affect the navigation of the river, damage the dams and riverbed structures on both sides of the river, and the construction is not limited by seasons. It has the characteristics of short construction period, few personnel, high success rate, safe and reliable construction, etc. Compared with other construction methods, the horizontal directional drilling rig has fast access to the site, and the construction site can be flexibly adjusted. Especially in urban construction, it can fully show its advantages, with less construction land, low project cost and fast construction speed.
The buried depth of urban pipe network is generally less than 3m. When crossing the river, it is generally 9-18m below the riverbed. Therefore, the 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 the requirements of environmental protection. The modern crossing equipment has high crossing accuracy, easy to adjust the laying direction and buried depth, and the arc laying distance of the pipeline is long, which can fully meet the buried depth required by the design, and can make the pipeline bypass the underground obstacles.
The construction of horizontal directional drilling rig will not hinder traffic, damage green space and vegetation, affect the normal life and work order of shops, hospitals, schools and residents, and solve the interference of traditional excavation construction on Residents' life, damage and adverse impact on traffic, environment and surrounding building foundation.
