[0026] When the present invention is in use, first push the fixing ring 407 with the rubber water stop 401 installed into the interior of the steel socket 2, at this time the fixing ring 407 is fitted with the inner wall of the steel socket 2, and then the other end of the rubber water stop 401 is snapped into the mounting groove 403 on the outer wall of the steel socket 2. Since the first steel ring 405 is composed of two "C"-shaped half rings, the two half rings of the first steel ring 405 are snapped into the first groove 404 on the rubber water stop 401 in turn, and then the connection between the two half rings is welded, and then the first bolt 406 is installed in the countersunk hole on the first steel ring 405, so that the end of the first bolt 406 is aligned with the countersunk hole The fixing ring 407 is threadedly connected, so that the fixing ring 407 and the rubber water stop 401 are fixed toward one end of the socket 3, thereby further increasing the stability of the installation of the rubber water stop 401; then the rubber ring 5 is placed on the end of the socket 3, and the second steel ring 7 is pressed into the second groove 6, so that the second steel ring 7 drives the rubber ring 5 to press against the end face of the socket 3, and then the second bolt 9 is used to fix the second steel ring 7 and the rubber ring 5 on the socket 3, so that the second steel ring 7 is fixed and cannot slide out of the second groove 6, thereby fixing the rubber ring 5. The installation of the second steel ring 7 has a shaping and supporting effect on the rubber ring 5, so that the rubber ring 5 It can press against the first pipe body 1; then the expansion waterstop 402 is engaged into the card groove 408 on the socket 3, and then the socket 3 of the second pipe body 1 is pushed toward the steel socket 2 of the first pipe body 1 which has been placed at the specified position using a pipe jacking machine or other equipment. Since the inner wall of the steel socket 2 and the inner wall of the socket 3 are both inclined structures, they have a guiding effect on the connection between the steel socket 2 and the socket 3, so that the socket 3 is moved to the inside of the steel socket 2. When the outer wall of the socket 3 contacts the rubber waterstop 401, the socket 3 drives the rubber waterstop 401 to deform and shrink, and continues to push the second pipe body 1 toward the inside of the steel socket 2 until the rubber ring 5 presses against the first The setting of the rubber ring 5 can increase the sealing performance of the connection between the two pipe bodies 1 and prevent the water inside the pipe body 1 from leaking outwards; when the socket 3 is fully inserted into the steel socket 2, the rubber waterstop 401 is aligned with the expansion waterstop 402, and the rubber waterstop 401 is reset and contacts the expansion waterstop 402, thereby forming a sealed environment at the connection between the steel socket 2 and the socket 3, and because the expansion waterstop 402 will expand by itself after encountering water and fill the gap to form an impermeable plastic colloid, the sealing effect of the socket interface of the two adjacent pipe bodies 1 is better, effectively preventing external water from seeping into the interior of the pipeline.
