1. It will not obstruct the traffic, destroy the green land and vegetation, and not affect the normal life and work order of shops, hospitals, schools and residents. It solves the interference of traditional excavation construction on the life of residents, the damage and adverse impact on traffic, environment and the foundation of surrounding buildings.
2. Modern crossing equipment has high crossing accuracy, easy to adjust laying direction and depth, and long arc laying distance, which can fully meet the design requirements of deep burial, and enable the pipeline to bypass underground obstacles.
3. The buried depth of urban pipe network is generally less than three meters. When crossing rivers, the buried depth is usually 9 to 18 meters below the riverbed.
4. When the horizontal directional drilling rig is used for crossing construction, there is no overwater or underwater operation, which will not affect the navigation of rivers or damage the dykes and riverbed structures on both sides of rivers. The construction is not restricted by seasons, and it has the characteristics of short construction period, less personnel, high success rate and safe and reliable construction.
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 can fully show its advantages, and the construction area is small, the project cost is low, and the construction speed is fast.
6. When crossing large rivers, pipelines are buried 9-18mm below the stratum, and there is little oxygen and other corrosive substances in the stratum. Therefore, natural anticorrosion and heat preservation can be performed to ensure longer operation time of pipelines.
Above are the construction characteristics of horizontal directional drilling rig, I hope to bring you help.
