More Information
Summary:The utility model provides a drainage tunnel inlet downstream blocking block. The drainage tunnel inlet downstream blocking block comprises a blocking block body, a reinforcing steel bar gabion loaded with stones and a dry stone slope protection. Reinforced gabions are arranged on the upstream side slope surface, the top surface and the downstream side bottom of the barrier main body, geotechnical cloth is laid on the surfaces of the reinforced gabions, and sprayed concrete is arranged on the outer side surface of the geotechnical cloth; a dry stone protection slope is arranged on the downstream side slope face of the blocking chopping body, and a boulder protection foot is further arranged on the outer side of the reinforced gabion at the bottom of the downstream side of the blocking chopping body. According to the technical scheme, the structure section type is simple, construction is rapid, economy and practicability are achieved, applicability is high, later dismantling is facilitated, and project investm
