As shown in fig. 3, a plurality of butt joint pipes 3 are horizontally arranged on the circumferential surface of the well body 1 (the number of butt joint pipes 3 in this embodiment is taken as an example), the axial lines of the butt joint pipes 3 are perpendicular to the axial line of the well body 1, and the butt joint pipes 3 and the well body 1 are prefabricated integrally.

As shown in fig. 3, the drain pipe 2 is a prefabricated pipe fitting made of concrete, the diameter of the outer peripheral surface of the drain pipe 2 is equal to the diameter of the inner wall of the butt joint pipe 3, and when the drain pipe 2 and the butt joint pipe 3 are mutually inserted, one end of the drain pipe 2 is inserted into the butt joint pipe 3, so that the outer wall of the drain pipe 2 is tightly attached to the inner wall of the butt joint pipe 3. The outer peripheral surface of the drain pipe 2 is also provided with an annular sealing plate 21, the plane of the annular sealing plate 21 is perpendicular to the central line of the drain pipe 2, and the annular sealing plate 21 is welded with the steel bars inside the drain pipe 2 when the drain pipe 2 is prefabricated, so that the annular sealing plate 21 protrudes out of the outer peripheral surface of the drain pipe 2 after concrete is poured and solidified. Annular shrouding 21 leaves the distance with drain pipe 2 grafting one end for behind drain pipe 2 and the mutual grafting of butt joint pipe 3, butt joint pipe 3 terminal surface supports and leans on one side at annular shrouding 21. A plurality of bolts 22 are arranged on the annular closing plate 21 in a penetrating way, and the bolts 22 are uniformly distributed along the outline of the annular closing plate 21. And the end surface of the butt joint pipe 3 is provided with a matching pipe 31 at the position corresponding to each bolt 22, the matching pipe 31 is prefabricated in the butt joint pipe 3, and the axis of the matching pipe 31 is parallel to the axis of the butt joint pipe 3. The bolt 22 is matched with the bolt 22 of the matching pipe 31, so that the drainage pipe 2 and the butt joint pipe 3 are fixed with each other more firmly.

As shown in fig. 4, a sleeve 4 is prefabricated on the inner wall of the port of the butt joint pipe 3, the axis of the sleeve 4 is coincident with the axis of the butt joint pipe 3, the diameter of the inner wall of the sleeve 4 is equal to that of the inner wall of the butt joint pipe 3, and one end face of the sleeve 4 is flush with the end face of the butt joint pipe 3. When the drain pipe 2 and the butt joint pipe 3 are inserted into each other, the sleeve 4 is attached to the outer peripheral surface of the drain pipe 2. Three ring grooves 42 are formed in the inner circumferential surface of the sleeve 4 along the axial direction of the sleeve 4, a plurality of partition plates 43 are respectively arranged in each ring groove 42 at intervals along the annular direction of the ring groove 42, and the edge of each partition plate 43 is fixedly connected with the inner wall of the ring groove 42, so that the ring grooves 42 are divided into a plurality of separation chambers 44 with the same size.
