The leakage hole 1 can be sealed by discharging sealing materials such as cement through the injection hole 3. The sealing materials belong to the prior art field, so they will not be elaborated here;

[0032] One end of the first connecting rod 7 away from the fixing member 5 is pin-connected to the support plate 9, and both ends of the second connecting rod 8 are pin-connected to the fixing member 5 and the middle end of the first connecting rod 7, respectively. The support plate 9 is an arc-shaped structure adapted to the water leakage hole 1. By setting the support plate 9 to an arc-shaped structure, the contact area between the support plate 9 and the water leakage hole 1 can be increased, so that the stability of the sealing pipe 4 in the water leakage hole 1 is effectively guaranteed, and the sealing support 10 is a concave structure;

[0038] The functional principle of the present invention can be elaborated through the following operation methods:

[0039] Under the existing technology, the leaking water is discharged through the drainage hole 2;

[0040] Then, the leaking part is expanded into a leaking hole 1 of a certain size by using the existing technology;

[0041] Place the sealing pipe 4 in the leaking hole 1, and then place the sealing support 10 on one side of the sealing pipe 4, so that the guide rod 11 on the sealing support 10 contacts the moving member 6, so that the moving member 6 drives the second connecting rod 8 to move, so that the second connecting rod 8 pulls the first connecting rod 7 to deflect with the fixed member 5 as the fulcrum, so that the first connecting rod 7 drives the supporting plate 9 to support the leaking hole 1, so that the sealing pipe 4 is fixed and limited at the leaking hole 1;

[0042] At the same time, the movement of the sealing support 10 causes the driven gear 14 to mesh with the active rack 12, so that the driven gear 14 drives the first screw 13 to rotate, and the first screw 13 drives the two first nuts 15 to move toward or in the opposite direction. When the two first nuts 15 move toward each other, they drive the fixing rod 16 to extend into the limiting groove, so that the sealing support 10 is fixed to the sealing pipe 4, and the sealing support 10 seals the water leakage hole 1;

When the two second nuts 29 move toward each other, the second nuts 29 pull the guide block 26 through the connecting rod 30 to move toward each other in the guide groove 23. When the two guide blocks 26 move toward each other, they can pull the third connecting rod 32 to deflect, so that the third connecting rod 32 drives the pressure plate 31 to press the sealing plate 17, so that the sealing plate 17 drives the sealing support 10 to move into the water leakage hole 1, so that the sealing plate 17 is installed on the ground-connected wall;

[0045] Use locking bolts to fix the limit plate 18 and the sealing plate 17 to the ground connection wall;

[0046] Finally, under the existing technology, sealing materials such as cement are discharged into the leakage hole 1 through the injection hole 3 to achieve a sealed treatment for the water seepage of the ground-connected wall.
