Diversion drainage structure for tunnel inside in water conservancy and hydropower project and construction method of diversion drainage structure
The invention discloses a diversion drainage structure for a tunnel inside in a water conservancy and hydropower project and a construction method for building the diversion drainage structure, and belongs to the technical field of design and construction of buildings in the water conservancy and hydropower project. The invention provides the diversion drainage structure for the tunnel inside in the water conservancy and hydropower project and the construction of the building construction method. The diversion drainage structure for the tunnel inside in the water conservancy and hydropower project is short in construction period, low in construction investment cost and capable of meeting the requirement of upward moving of an opening of a diversion drainage tunnel. The construction method includes that a section of a drainage tunnel is constructed on the upstream side of a drainage tunnel body in a river flow direction, a construction maintenance diversion tunnel which communicates the drainage tunnel and the drainage tunnel body is constructed before the drainage tunnel and the drainage tunnel body are communicated, the requirement for temporary diversion drainage of an upstream river channel is met, then the connection position of the drainage tunnel and the drainage tunnel body is completely broken through, a waste upper section of the drainage tunnel body is blocked, finally, simultaneous drainage of the drainage tunnel and the downstream section of the drainage tunnel body as well as the drainage tunnel, the construction maintenance diversion tunnel and the downstream section of the drainage tunnel body is realized.
