The method comprises the following steps: S1, the installation of the preset pipe, the installation of the preset sleeve (2) is preset, before pouring the basement wall (6), the installation position of the preset sleeve (2) is reserved in the upper part of the basement wall (6), when pouring the basement wall (6), the preset sleeve (2) is clamped in the gap of the steel support through the fixing ring seat (9) in the upper part of the preset sleeve (2), then the basement wall (6) is poured, after the basement wall (6) is coagulated, the preset sleeve (2) is embedded with the basement wall (6) as a whole, the installation of the preset sleeve (2) is completed; S2, installation preparation, before installing the wall pipe body (1), the inner surface of the first sleeve hole (10) in the middle of the preset sleeve (2) is cleaned, the dust and residual cement particles in the first sleeve hole (10) are removed, and sealing paste is applied in the first sleeve hole (10), the sealing paste should be evenly applied and not too much, then the rubber sleeve (4) is placed on the inner side of the first sleeve hole (10), after that, the surface of the connection of the wall pipe body (1) is cleaned to ensure the cleanliness of the surface of the connection of the wall pipe body (1); S3, pipe body installation, after the preparation work is completed, the fixed rubber sleeve (8) is sleeved on the outside of the wall pipe body (1), then the conical sleeve (3) is sleeved on the upper part of the wall pipe body (1) through the second sleeve hole (13), after sleeving, it should be ensured that the conical sleeve (3) is completely sleeved on the outside of the fixed rubber sleeve (8), after that, liquid sealant is dripped in the gap between the fixed rubber sleeve (8) and the wall pipe body (1), the gap is closed, then the wall pipe body (1) is lifted horizontally, the four fixed bolts (5) are sequentially installed in the fixed through hole (14) in the upper part of the sleeve fixing seat (11), and the thrust spring (7) is sleeved on the end of the fixed bolt (5), then one end of the wall pipe body (1) is inserted into the inner side of the third sleeve hole (16), the wall pipe body (1) is kept horizontal and moved to one side, so that the conical sleeve (3) is inserted into the inside of the third sleeve hole (16), at the same time, it should be ensured that the fixed bolt (5) is aligned with the connecting through hole (17) in the upper part of the rubber sleeve (4) when inserting, after inserting, the sleeve fixing seat (11) is pushed inward with force, and the fixed bolts (5) in the upper part of the sleeve fixing seat (11) are sequentially screwed, the conical sleeve (3) is subjected to extrusion force, the rubber sleeve (4) is pushed and pressurized by the conical sleeve (3), the sealing and fixing of the wall pipe body (1) are completed, and the installation work is completed.
