How to design and construct the trajectory of overhead insulated steel pipes
The causes of accidents in horizontal directional drilling of overhead insulated steel pipes can be roughly divided into broken drilling tools, drill pipe burying and sticking, flat and immovable pipes when the pipes are pulled back, and damage to the original underground buildings. The reasons for the breakage of drilling tools: ① The drilling tool has excessive wear after long-term use; ② The drill pipe is thin and worn, and when drilling guide holes, the curvature radius is too small. The drill pipe breaks under repeated shear forces. Preventive measures: Regularly inspect drilling tools. No need to wear and exceed the limit of drilling tools.
