An intelligent relay drainage system suitable for tunnel reverse slope excavation

Abstract

The application provides an intelligent relay drainage system suitable for tunnel reverse slope tunneling, comprising: a tunnel; a tunnel face is arranged on one side of the tunnel, a catch basin is arranged on one side of the bottom of the inner cavity of the tunnel face, and a first-stage drainage device is arranged on one side of the catch basin. The application provides an intelligent relay drainage system suitable for tunnel reverse slope tunneling, which is connected with a catch basin and a multi-stage drainage device, does not need to dig multiple catch basins, does not need to observe the water levels of multiple catch basins, and does not need workers to observe the water discharge condition. The multi-stage drainage device continuously guides water flow and filters and discharges the water flow multiple times, does not need to set a sedimentation tank outside the hole, does not need to consider the size of the sedimentation tank, continuously discharges the sewage into nearby water systems after multiple treatments, is simple and convenient to operate, reduces the exposure time of workers in a dangerous environment, reduces the engineering land cost, and realizes intelligent control of drainage.
