The invention discloses a blocking structure of a hydraulic engineering diversion tunnel perpetual plug. The blocking structure comprises a diversion tunnel, a grouting pipe, the plug, an upstream slope, a downstream slope and a rock mass; the plug is arranged inside the diversion tunnel, the bottom of the plug is connected with the rock mass, the bottom of the plug is provided with the upstream slope, the upstream slope is connected with the downstream slope, a red copper water stop belt is connected with the plug, a water drainage steel pipe is fixedly installed inside the rock mass, the bottom of a reinforcing steel bar pile is arranged inside the rock mass, the other end of the reinforcing steel bar pile is connected with the plug, and the grouting pipe is connected with the plug. Theblocking structure of the hydraulic engineering diversion tunnel perpetual plug is better in stability, at least the cross sectional area of one part of the plug is larger than the cross sectional area of the diversion tunnel, and therefore the plug can be better clamped between the diversion tunnel and the rock mass; and as the plug is good in stability, the diversion tunnel can be plugged with the short plug, materials are better saved, and the construction time is shortened.
Description
technical field [0001] The invention relates to the technical field of water conservancy diversion tunnel plugging, in particular to a plugging structure for a permanent plug of a water conservancy diversion tunnel. Background technique [0002] Diversion and drainage structures refer to temporary drainage structures that guide river water downstream during the construction of water conservancy and hydropower projects. Commonly used diversion and drainage structures include diversion open channels, diversion tunnels, diversion bottom holes, diversion culverts, etc. Aqueducts or factory draft pipes can also be used as diversion and drainage structures. After the diversion and drainage structure completes the task of diversion and drainage, it is usually necessary to block the diversion and drainage structure. Generally, the closure of the diversion tunnel is usually blocked by pouring concrete plugs. The diversion The hole can be a diversion tunnel or a diversion culvert, th...
