Description

Technical Field

[0001] The utility model mainly relates to the technical field of water conveyance tunnels, and specifically relates to a seepage prevention structure for a water conveyance tunnel. Background Technique

[0002] A water conveyance tunnel is an important part of a reservoir project. It is a tunnel-like structure system developed in a mountain during the construction of the reservoir and is the main way to supplement water resources in water-scarce areas.

[0003] Pipes are usually laid in the water conveyance tunnel. To ensure the sealing between two pipes, a sealing pipe is usually fixed outside the joint of two pipes to avoid water seepage. Since the sealing pipe is directly fixed at the joint of two pipes, when the pipes vibrate due to the passing of vehicles or other reasons, the pipes will be displaced, making the protection pipe fixed between the two pipes easily pulled and damaged. Therefore, a new seepage prevention structure for a water conveyance tunnel is needed. Summary of the Utility Model

[0022] Please refer specifically to the attached Figure 1-2 , an anti-seepage structure for a water conveyance tunnel, comprising a tunnel body 1. A plurality of pipes 2 are laid in the tunnel body 1. A sealing pipe 3 is slidably connected to the annular inner surface at the contact position of two adjacent pipes 2. Fixed rings 5 are slidably connected to the annular inner surface on one side of the contact position of two adjacent pipes 2. Annular grooves are formed on the opposite surfaces of the two fixed rings 5. The two ends of the sealing pipe 3 are respectively inserted into the two annular grooves. A plurality of circular grooves are arranged at equal intervals in the annular grooves. A round rod 6 is inserted into the circular groove. One end of the round rod 6 in the circular groove is fixedly connected to a first elastic member 7. The first elastic member 7 is a spring. The first elastic member 7 is in a normal state. The end of the first elastic member 7 away from the round rod 6 is fixedly connected in the circular groove. A circular hole is formed on the side of the sealing pipe 3 facing the circular groove. The end of the round rod 6 away from the circular groove is inserted into the circular hole.

[0023] By inserting the protection pipe into the grooves formed in the two fixed rings 5 and fixing it with the telescopic structure composed of the first elastic member 7 and the round rod 6, when the pipes 2 are misaligned, the protection pipe can move between the two fixed rings 5, thereby reducing the probability of damage.

[0024] On one side of the pipe 2 facing the fixed ring 5, a plurality of annularly and equidistantly arranged slots are formed. On the surface of the fixed ring 5 facing the slots, a groove is formed. A sliding plate 11 is slidably connected in the groove. On the surface of the sliding plate 11 facing the slots, a second elastic member 12 is fixedly connected. The second elastic member 12 is a spring. The second elastic member 12 is in a slightly compressed state. The end of the second elastic member 12 away from the sliding plate 11 is fixedly connected to a plug board 13. The end of the plug board 13 away from the second elastic member 12 is inserted into the slot.

[0025] The fixed ring 5 is fixed in the pipe 2 by using the plugging structure composed of the plug board 13, the second elastic member 12 and the sliding plate 11, so as to facilitate the installation and disassembly of the fixed ring 5, facilitate maintenance and replacement, and reduce the maintenance cost.

[0026] On the surface of the sliding plate 11 away from the plug board 13, a bearing 10 is fixedly connected. A screw rod 9 is fixedly connected inside the bearing 10. A plurality of threaded holes communicating with the groove are formed on the annular inner surface of the fixed ring 5. The end of the screw rod 9 away from the bearing 10 is threadedly connected in the threaded hole.

[0027] In order to prevent rusting in the threaded hole during water conveyance, a sealing plug 8 for plugging the threaded hole is threadedly connected to the side of the inner surface of the threaded hole away from the screw rod 9.

[0028] In order to ensure the sealing performance between both ends of the sealing ring 4 and the fixed ring 5, a sealing ring 4 is fixedly connected in the annular groove. The sealing ring 4 is sleeved on the annular surface of the sealing pipe 3.

[0029] The specific operation process of the present utility model is as follows: During installation, first fix a fixed ring 5 by adjusting the position of the screw rod 9 in the threaded hole. Then insert one end of the sealing pipe 3 into the annular groove of the fixed ring 5, and insert the round rod 6 of the fixed ring 5 into the small hole of the sealing pipe 3. Then rotate another fixed ring 5 so that the round rod 6 of the fixed ring 5 is inserted into the small hole of the sealing pipe 3, and the plug board 13 is inserted into the slot of the pipe 2. After installation, adjust the position of the screw rod 9 in the threaded hole for fixation.

[0030] When the pipe 2 is displaced due to vibration, the protection pipe can move between the two fixed rings 5. Since sealing rings 4 are arranged at both ends of the sealing pipe 3, slight displacement will not affect the sealing of the connection between the two pipes 2 by the sealing pipe 3, thereby reducing the probability of damage.

[0031] The above has made an exemplary description of the present utility model in conjunction with the drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
