After the two adjusting grooves 41 are released, the two clamping blocks b62 are prompted to move relative to each other and be clamped into the corresponding clamping groove b621 under the rebound action of the spring, and the clamping blocks a61 are simultaneously moved from the insertion groove 64 to the clamping groove a611 to achieve clamping and locking. In this way, the installation efficiency between the drainage component and the installation component is greatly improved, and there is no need to use a number of screws in combination with a plurality of L-shaped installation ears for fixed installation. In addition, in this process, since the two adjustment grooves 41 are relative to one end under the rebound action of the length adjusting member 5, and the plug-in blocks a71 are prompted to plug and fix the two relatively aligned sockets 74, when the drainage component is clamped and fixed to the installation component through the cooperation of the length adjusting member 5 and the clamping fixing member 6, the clamping and fixing installation of the two downpipes 43 can be achieved simultaneously, thereby further improving the installation efficiency of the overall waterproof structure drainage system.
