Detailed Implementation

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: It includes a plug rod 1, a base 2, and a connecting rod 3. The upper end of the plug rod 1 is fixedly fitted with the base 2. Four connecting rods 3 are distributed with equal rounded corners on the outer ring wall of the base 2. An annular groove 19 is opened at the bottom of the base 2, and a first sealing ring 20 is fixedly installed in the annular groove 19. The first sealing ring 20 can improve the sealing between the base 2 and the inner wall of the railway tunnel, and prevent water from seeping out from the gap between the base 2 and the inner wall of the railway tunnel. Reinforcing ribs 25 are fixedly installed on both sides of the connecting rod 3, and the reinforcing ribs 25 are fixedly connected to the outer ring wall of the base 2. The reinforcing ribs 25 can improve the structural strength of the connection between the base 2 and the connecting rod 3, thereby enabling the base 2 and the connecting rod 3 to have strong load-bearing capacity.

[0027] It also includes:

[0028] The expansion sealing ring 4 consists of three rings, all of which are fixedly sleeved on the insert rod 1. Four expansion sealing blocks 5 are distributed with equal rounded corners between two adjacent expansion sealing rings 4 on the insert rod 1. Four partitions 6 are distributed with equal rounded corners between two adjacent expansion sealing rings 4 on the insert rod 1, and the partitions 6 are fixedly positioned between two adjacent expansion sealing blocks 5.

[0029] The leak-stopping tube 7 is movably inserted into the insertion rod 1. Both ends of the leak-stopping tube 7 are closed structures. Several liquid inlets 8 are opened at the upper corners of the outer ring wall of the leak-stopping tube 7 with equal rounded corners. A flow groove 14 that cooperates with the liquid inlets 8 is opened in the insertion rod 1. Several liquid outlets 9 are opened at the lower corners of the outer ring wall of the leak-stopping tube 7 with equal rounded corners. Second sealing rings 22 are fixedly installed in the grooves 21 opened on the upper and lower sides of the liquid inlets 8 and liquid outlets 9 on the outer ring wall of the leak-stopping tube 7. The second sealing rings 22 are movably abutting against the inner wall of the insertion rod 1. Multiple sealing rings 22 can achieve multiple seals at the gap between the leak-stopping tube 7 and the inner wall of the insertion rod 1, which greatly improves the sealing performance between the leak-stopping tube 7 and the insertion rod 1.

[0030] The movable block 10 is fixedly sleeved on the plugging tube 7 and is movably abutted in the movable groove 11 opened inside the insert rod 1. A first spring 12 is movably sleeved on the plugging tube 7. The two ends of the first spring 12 are fixedly connected to the movable block 10 and the bottom wall of the movable groove 11, respectively. Several guide blocks 23 are evenly rounded on the outer ring wall of the movable block 10 and are movably installed in the strip groove 24 opened on the inner wall of the movable groove 11. The guide blocks 23 can guide the movement of the plugging tube 7 in the insert rod 1 and limit its extreme position, so as to prevent the plugging tube 7 from rotating during its movement in the insert rod 1.

[0031] The extrusion block 13 is fixedly installed at the upper end of the plugging pipe 7, and the extrusion block 13 has several flow ports 15 with rounded corners. The insertion rod 1 is provided with a limiting mechanism 16 connected to the extrusion block 13.

[0032] The limiting mechanism 16 includes:

[0033] Limiting blocks 16-1, there are two limiting blocks 16-1, which are respectively movably inserted into the grooves 17 opened on the left and right sides of the inner wall of the insert rod 1. A second spring 16-2 connected to the limiting block 16-1 is fixedly installed in the groove 17. A limiting groove 18 that cooperates with the limiting block 16-1 is opened on the annular side wall of the extrusion block 13.

[0034] There are two control rods 16-3, which are fixedly mounted on two limit blocks 16-1 respectively. One end of the control rod 16-3 passes through the insert rod 1 and the base 2 and is fixedly mounted with a control handle 16-4. Under the influence of the rebound thrust applied by the second spring 16-2, the limit block 16-1 can realize the limiting function of the extrusion block 13 in the lowest position.

[0035] When using this invention, insert rod 1, expansion sealing ring 4, and expansion sealing block 5 are inserted into the leak point, and base 2 and connecting rod 3 abut against the inner wall of the railway tunnel. Bolts are then passed through the through hole on connecting rod 3 and screwed into the inner wall of the railway tunnel to fix the leak-sealing device to the inner wall of the railway tunnel. At the same time, expansion sealing ring 4 and expansion sealing block 5 expand when exposed to water and abut against the inner wall of the leak point, achieving rapid sealing of the leak point. When it is necessary to inject the leak-sealing material into the leak point, the external injection pipe abuts against the squeezing block 13 and is inserted into insert rod 1. Squeezing block 13 drives the leak-sealing pipe 7 to move downward, causing the leak-sealing pipe 7 to drive the movable block 10 to move downward and compress spring 12. Squeezing block 13 is also affected by the rebound thrust applied by spring 2 16-2 and abuts against the limiting groove 18, achieving the sealing of the leak-sealing pipe 7 and the squeezing block 13. The position is limited, and the outlet 9 of the plugging tube 7 protrudes from the insertion rod 1. At this time, the flow port 15 can also communicate with the flow groove 14. Then the plugging material is injected. The plugging material enters the plugging tube 7 through the flow port 15, the flow groove 14 and the inlet 8 in sequence. Finally, the plugging material flows into the leak point from the outlet 9 to seal it. After the leak point is sealed by the plugging material, the control lever 16-4 is pulled away from the base 2. The control lever 16-4 drives the limiting block 16-1 to disengage from the limiting groove 18 and move into the groove 17, compressing the second spring 16-2. This causes the first spring 12 to return to its original position and push the movable block 10 upward. The movable block 10 drives the plugging tube 7 to move upward. The plugging tube 7 drives the squeezing block 13 to move upward, so that the plugging tube 7 and the squeezing block 13 return to their original positions, thus sealing the inside of the insertion rod 1.

[0036] Compared with the prior art, the beneficial effects of this utility model are:

[0037] 1. Through the cooperation of expansion sealing ring 4, expansion sealing block 5, partition 6, leak-stopping pipe 7, movable block 10, No. 1 spring 12 and extrusion block 13, not only can the leak point be quickly plugged in an emergency, but the filling material can also be injected into the leak point without pulling it out in the subsequent filling process, which improves the convenience of use.

[0038] 2. By cooperating with the limiting mechanism 16, the rebound force applied by the second spring 16-2 to the limiting block 16-1 can be used to limit the extrusion block 13 in its lowest position.

[0039] 3. Multiple sealing rings 22 can achieve multiple seals at the gap between the plugging tube 7 and the inner wall of the insertion rod 1, greatly improving the sealing performance between the plugging tube 7 and the insertion rod 1;

[0040] 4. The reinforcing rib 25 can improve the structural strength of the connection between the base 2 and the connecting rod 3, thereby enabling the base 2 and the connecting rod 3 to have a stronger load-bearing capacity.

[0041] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
