DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The mounting block 15 is arranged to facilitate the installation of the preinstalled pipe 1.

[0021] See also Figure 1-5 A stabilizing ring 4 is fixedly connected to the inner wall of the pre-installed pipe 1 , and the inner wall of the stabilizing ring 4 is in contact with the surface of the pre-buried pipe 2 .

[0022] See also Figure 1-5 A ring member 5 is fixedly connected to the surface of the embedded pipe 2, a slot 6 is fixedly connected to the left side of the ring member 5, an insertion rod 7 is fixedly connected to the right side of the stabilizing ring 4, and one end of the insertion rod 7 away from the stabilizing ring 4 is movably inserted into the slot 6.

[0023] See also Figure 1-5 A matching ring 8 is fixedly connected to the right side of the stabilizing ring 4. A sealing ring 9 is movably sleeved on the surface of the annular member 5. The sealing ring 9 and the matching ring 8 are tightly squeezed. The sealing ring 9 is specifically made of rubber. The contact surfaces of the sealing ring 9 and the matching ring 8 are both inclined. This is to facilitate the squeezing of the sealing ring 9 and improve the sealing effect. The sealing ring 9 is movably sleeved on the annular member 5, which makes the sealing ring 9 removable and replaceable.

[0024] See also Figure 1-5 A slide groove 10 is opened on the right side of the ring member 5, a telescopic rod 11 is fixedly connected to one side of the inner wall of the slide groove 10, an end of the telescopic rod 11 is fixedly connected to a moving plate 12, and the locking rod 3 is fixedly connected to the moving plate 12.
