Side slope drainage system

The utility model discloses a side slope drainage system, including setting up in the inside drainage hole of side slope, be provided with the wash port on the drainage hole, the sliding surface fed through at the bottom of ear hole and side slope were passed through to the drainage hole, still was provided with the first guide hole that is used for surveying drainage hole rimrock stone thickness on the drainage hole. A side slope drainage system, is through the setting in first guide hole and ear hole, has guaranteed the country rock geological conditions of the feasibility and the drainage hole cavitation of wash port, can accurate definite drainage hole axis position, the drainage hole can be done simultaneously in the ear hole, and groundwater in the discharge slip mass improves the stability of slip mass, the monitoring hole still can be done simultaneously in the ear hole, through the installation monitoring instrument, lasts ground deep deformation monitoring, in addition, the simple structure of this system, it is with low costs, easily promote.
