[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 5As shown, a waterproof reinforcement structure for pipe joints in a municipal engineering jacking construction comprises a first jacking pipe 1 and a second jacking pipe 2 which can be docked with each other, a circular mounting ring 3 is fixedly mounted on the inner side wall of the end of the second jacking pipe 2 which is opposite to the first jacking pipe 1, and a positioning block 5 with a positioning hole is fixedly mounted in a circumferential array on the inner side wall of the circular mounting ring 3. Since the positioning block 5 is provided with a positioning hole, it is convenient to fix it with a positioning rod and a positioning plate 705, a connecting sealing ring 6 is fixedly connected to one end of the second jacking pipe 2, a rotatable docking assembly 7 is provided on the inner side wall of the end of the first jacking pipe 1 which is opposite to the second jacking pipe 2, and a positioning assembly 8 for positioning the rotatable docking assembly 7 is installed on the inner side wall of one end of the first jacking pipe 1.

[0024] A circular mounting ring 701 is fixedly mounted on the inner side wall of one end where the first top pipe 1 and the second top pipe 2 are connected, and a water pipe 702 is rotatably mounted on the inner side wall of the circular mounting ring 701. A second sealing ring 703 is fixedly connected to the inner side wall of one end of the first top pipe 1, and the second sealing ring 703 is arranged on the outer side of the water pipe 702. A docking ring 704 is fixedly connected to one end of the first top pipe 1, and a positioning plate 705 with a positioning rod is fixedly mounted in a circumferential array on the inner side wall of the docking ring 704. The positioning rod of the positioning plate 705 can be correspondingly connected to the positioning hole of the positioning block 5. The water pipe 702 can rotate in the circular mounting ring 701, and the second sealing ring 703 can seal the outside of the water pipe 702.

[0025] The positioning assembly 8 includes a mounting base 801 fixed on the inner side wall of the first jacking pipe 1. A threaded hole is provided on the mounting base 801. A countersunk fixing screw 802 is threadedly connected to the inner thread of the threaded hole. One end of the countersunk fixing screw 802 conflicts with the outer side wall of the water pipe 702. When the water pipe 702 rotates, it can drive the docking ring 704 and the positioning plate 705 to rotate. After the water pipe 702 rotates, the user can limit the water pipe 702 and the positioning plate 705 through the countersunk fixing screw 802, and the countersunk fixing screw 802 does not affect the connection between the first jacking pipe 1 and the second jacking pipe 2.

[0026] An outer fixing ring plate 9 with a connecting groove on the side is fixedly installed on the outer side wall of one end of the first jacking pipe 1, and an outer fixing annular insert plate 10 is fixedly installed on the outer side wall of one end of the second jacking pipe 2. The outer fixing annular insert plate 10 is inserted into the connecting groove on the side of the outer fixing ring plate 9. A fixing bolt 11 is threadedly connected to the outer fixing ring plate 9. After the outer fixing annular insert plate 10 is connected to the outer fixing ring plate 9 by the fixing bolt 11, the first jacking pipe 1 and the second jacking pipe 2 can be fixedly connected.

[0027] When the present invention is in use, when the first jacking pipe 1 is connected to the second jacking pipe 2, the user can first drive the water pipe 702 and the docking ring 704 to move toward the second jacking pipe 2 by the first jacking pipe 1, thereby driving the positioning plate 705 to move toward the second jacking pipe 2. Before the first jacking pipe 1 is docked with the second jacking pipe 2, if the position of the positioning plate 705 deviates from the position of the positioning block 5, the user can rotate the water pipe 702 in the circular mounting ring 701, thereby driving the docking ring 704 and the positioning plate 705 to rotate, without rotating the first jacking pipe 1. After the water pipe 702 and the positioning plate 705 have been rotated, the user can limit the water pipe 702 and the positioning plate 705 by the countersunk fixing screw 802. Then the user can insert the positioning plate 705 into the positioning block 5 in the second top tube 2. Since the positioning plate 705 is provided with a positioning insertion rod, the first top tube 1 can be connected to the second top tube 2 at this time. After the first top tube 1 and the second top tube 2 are connected, the docking ring 704 will squeeze the first sealing ring 4 on one side of the circular mounting ring 3, thereby increasing the sealing performance at the docking ring 704 and the circular mounting ring 3. At this time, the connecting sealing ring 6 will be between the first top tube 1 and the second top tube 2, and the sealing performance is good. After the first top tube 1 and the second top tube 2 are connected, the outer fixed annular insert plate 10 can be placed in the connecting groove on the side of the outer fixed ring plate 9, and then the user rotates the fixing bolt 11 to complete the connection between the first top tube 1 and the second top tube 2.
