In engineering, a side slope refers to a slope which is manually excavated or constructed, such as a highway side slope, a dyke side slope, an earthwork side slope and the like, and the stability of the side slope is critical to the safety of engineering.
When the side slope is unstable and the slope body is easy to collapse, the main reason is that excessive water contained in the slope body is not discharged in time. Therefore, the stability of the side slope can be improved by draining the side slope, the adverse effect of water on the side slope is reduced, and the safety of the soil body and the structural objects of the side slope is protected.
When draining the deep part of the side slope, a deep drainage system is needed to be drilled and paved to guide the underground water out from the inside so as to reduce the problem of the stability of the side slope caused by the pressure of the underground water and the lifting of the underground water level. The drilling mode can adopt a horizontal directional drill to carry out straight drilling with a certain inclination angle, and after the drilling is finished, pipelines are conveniently paved to lead out excessive accumulated water in the pipeline.

2. Because the pipeline inserted into the deep part of the side slope has a certain length, the stable and continuous entering of the pipeline section required to be inserted into the drill hole is difficult to ensure, the inner wall of the drill hole is easily damaged once the insertion deviation occurs in the process of inserting the pipe, so that the internal collapse is caused, the smooth insertion of the pipeline is influenced, and the pipeline laying efficiency is influenced.
Therefore, in order to solve the problems that the inclination angle is difficult to find in the pipeline laying process and the inclination angle is unstable and easy to deviate in the intubation process, the invention provides a slope drainage method by utilizing a horizontal directional drill.
