Abstract
Description
Technical Field
[0001] The invention relates to the technical field of pipeline waterproof sealing, and in particular to a waterproof structure at a pipeline interface of a municipal engineering project. Background Art
[0002] At present, waterproofing of pipe interfaces is an important link in municipal engineering. By using specific materials and technologies, a closed space that can effectively prevent water penetration and leakage is constructed at the joints of the pipe system (such as the interfaces between pipes, the interfaces between pipes and equipment, etc.), at the crossing structures (such as pipes passing through walls, floors, etc.), and at places where there are gaps or weak links in the pipes themselves.
[0003] Traditional waterproofing measures mainly include the use of rubber rings, sealing strips and threaded connections. Although these methods can meet basic waterproofing needs to a certain extent, there are still many problems in long-term operation. Rubber rings are prone to aging and deformation, resulting in reduced sealing effect. Sealing strips are greatly affected by changes in ambient temperature and may crack or fall off. Threaded connections may cause leakage due to improper construction. With the acceleration of urbanization, the waterproofing requirements for pipeline interfaces are getting higher and higher. The above methods can only solve the short-term waterproofing needs of pipelines, thereby shortening the service life of the waterproof structure of the pipeline interface and causing leakage after long-term use.

The modified epoxy resin has good corrosion resistance, which prolongs the service life of the waterproof sleeve. Flange 2 is installed on the surface of the waterproof sleeve, and flange 1 is installed on the surface of the pipe body 1. Flange 1 and flange 2 are connected by threaded rods and nuts, which makes the pipe body 1 close to the inside of the waterproof sleeve.

The elastic sealing ring 1 8 and elastic sealing ring 2 9 are both composed of EPDM rubber, which has excellent aging resistance such as ozone resistance, heat resistance, and weather resistance, and also has good elasticity and compression resilience, so that the elastic sealing ring 1 8 and elastic sealing ring 2 9 are not easy to age and can be firmly installed on the surface of the pipeline body 1 and pipeline body 2 3, further increasing the sealing performance of the interface.
[0024] See attached Figure 5 and attached Figure 6The interior of the waterproof sleeve 2 is fixedly connected with a watering pipe 13, the interior of the watering pipe 13 is fixedly connected with a watering pipe 2 14, and the outer wall of the watering pipe 2 14 is fixedly connected to the inner wall of the waterproof sleeve 2; the outer wall of the watering pipe 13 is arranged inside the pouring groove 12, and the outer wall of the watering pipe 2 14 is arranged inside the pouring groove 12; Specifically, firstly, a watering pipe 13 is installed inside the waterproof sleeve 2, and a watering pipe 2 14 is symmetrically installed on both sides of the watering pipe 13, and water-stop glue is poured at the opening of the watering pipe 13. The main component of the water-stop glue is polyurethane. When the water-stop glue comes into contact with water, carbon dioxide gas is released, thereby expanding the volume of the material.

This allows maintenance personnel to regularly add water-stop glue to the pouring groove 12 through the watering pipe 13 and the watering pipe 2 14 to avoid gaps in the water-stop glue at the pipe interface due to long-term consumption, thereby achieving the effect of avoiding water leakage at the pipe interface.
[0025] See attached Figure 6 -Attached Figure 8 A valve assembly is provided on the upper surface of the irrigation pipe 13, and the valve assembly is used to control the input speed of the water stop glue; the valve assembly includes a housing shell 16, the lower surface of the housing shell 16 is fixedly connected to the upper surface of the irrigation pipe 13, the upper surface of the housing shell 16 is fixedly connected to a cover plate 17, the interior of the housing shell 16 is slidably connected to a turntable 18, the outer wall of the turntable 18 is fixedly connected to a handle 19, the inner wall of the turntable 18 is provided with a slide groove 23, and the inner wall of the turntable 18 is slidably connected to a stopper 20; the inner fixed connection of the stopper 20 A slider 21 is connected, a slide groove 22 is provided on the inner wall of the housing 16, the outer wall of the slider 21 is slidably connected to the inside of the housing 16 through the slide groove 22, a slide groove 27 is provided on the inner wall of the housing 16, and the outer wall of the handle 19 is slidably connected to the inner wall of the housing 16 through the slide groove 27; a liquid injection hole 24 is provided inside the cover plate 17, a liquid injection hole 25 is provided inside the turntable 18, a liquid injection hole 3 26 is provided inside the housing 16, and the outer wall of the stopper 20 is slidably connected to the inside of the slide groove 23; Specifically, the handle 19 is driven to slide along the inner wall of the accommodating shell 16 through the third slide groove 27 by toggling the handle 19. Since the turntable 18 is fixedly connected to the handle 19, the turntable 18 rotates inside the accommodating shell 16 driven by the handle 19. Then, the stopper 20 slides along the second slide groove 23 driven by the turntable 18. The third slide groove 27 further limits the rotation angle of the turntable 18 by limiting the rotation range of the handle 19. This causes the stopper 20 to rotate along a specified trajectory. Since the stopper 20 is fixedly connected to the slider 21, Driven by the stop block 20, the slider 21 slides on the inner wall of the containing shell 16 through the slide groove 1 22. At this time, the slider 21 no longer covers the injection hole 25 and the injection hole 3 26. The water-stop glue can enter the interior of the pouring pipe 13 through the injection hole 1 24, the injection hole 25 and the injection hole 3 26 in sequence to pour the pouring groove 12, thereby finally achieving the purpose of controlling the shielding area of the stop block 20, thereby achieving the effect of controlling the pouring speed of the water-stop glue and preventing air from entering the pouring groove 12 to generate bubbles and destroy the sealing after the pouring is completed.
