[0017] Furthermore, a flange extending downward is fixedly connected along the edge of the cover, and the upper end of the funnel is inserted into the flange and fits against the inner wall of the flange.

[0018] Through the above arrangement, the stability of the cover on the upper side of the funnel can be increased to prevent the cover from shifting.

[0019] Furthermore, the inner wall of the guide sleeve fits the outer wall of the output end of the funnel.

[0020] Through the above arrangement, the sealing between the guide sleeve and the output end of the funnel is increased, which facilitates the pouring of concrete. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In the present application, the base 31 and the guide sleeve 32 are an integrally formed structure, which is convenient for processing and installation; the guide sleeve 32 is cylindrical; the sliding sleeve 33 is cylindrical, and the outer diameter of the sliding sleeve 33 is adapted to the inner diameter of the guide sleeve 32, which, on the one hand, improves the stability of the sliding sleeve 33 sliding up and down, and on the other hand, ensures the sealing between the sliding sleeve 33 and the guide sleeve 32; during construction, the drain pipe has been vertically installed on the upper side of the prefabricated board in advance, the base 31 is placed on the prefabricated board, the drain pipe passes through the through hole 311, and the output end of the funnel 34 is inserted into the drain pipe. The funnel 34 can be driven to move upward or downward through the lifting mechanism 35, so that the height of the upper side of the funnel 34 is higher than the concrete to be poured. The designed thickness is such that after pouring concrete, the upper side of the concrete is lower than the upper side of the funnel 34, which is convenient for installing the cover 4 on the upper side of the funnel 34; wherein, when the funnel 34 moves, the sliding sleeve 33 and the guide sleeve 32 move relative to each other, and the guide sleeve 32 enables the sliding sleeve 33 to move upward or downward stably, thereby improving the stability of the funnel 34; in addition, the lifting mechanism 35 can adopt devices such as a cylinder or a push rod, or adopt other forms, which can be selected according to needs; under the support of the lifting mechanism 35, the funnel 34 has good bearing performance, and the drainage equipment can be directly installed on the upper side of the cover 4, which is convenient for later decoration; the water output by the drainage equipment enters the drainage pipe after passing through the water inlet and the funnel 34.
