Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to an anti-seepage device for water supply and drainage pipelines used in municipal construction. Background Art

[0002] Urban development relies on the support of infrastructure, and municipal engineering construction prioritizes water supply and drainage pipeline construction. During housing construction, the quality of water supply and drainage pipeline construction directly determines the overall quality of the project. Water supply and drainage pipelines are crucial for ensuring residents' regular water supply and providing daily water. During the life of a building, repairing leaks in water supply and drainage pipelines not only consumes significant manpower and financial resources but also disrupts residents' daily lives. Therefore, construction teams must ensure the quality of water supply and drainage pipeline anti-leakage work to prevent subsequent leaks.

[0003] Currently, in the existing technology for connecting and laying water supply and drainage pipes for municipal construction, sealing rings are often used to achieve sealing between pipes. However, this sealing connection method has disadvantages and is prone to leakage. The main reason is that the connection parts of water supply and drainage pipes are generally connected by plug-in connection. Therefore, if the laying direction of the two pipe sections deviates or is misaligned, it will cause the pipe to leak. Therefore, the unstable plug-in structure between the two pipe sections is also a major cause of leakage. To improve this situation, it is necessary to design an anti-seepage device for water supply and drainage pipes for municipal construction. Utility Model Content

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1-4The anti-seepage device for water supply and drainage pipes for municipal construction includes a first pipe 1 and a second pipe 2. The first pipe 1 and the second pipe 2 are both water supply and drainage pipes with the same structure to be laid. The first pipe 1 and the second pipe 2 are two adjacent and relatively connected water supply and drainage pipes, and also include an anti-seepage connection mechanism. The first pipe 1 and the second pipe 2 are connected to each other and communicated with each other through the anti-seepage connection mechanism. In this embodiment, only water supply and drainage pipes with the same diameter at both ends are introduced. Of course, different diameters at both ends of a pipe can also be achieved by changing the connection size at both ends of the anti-seepage connection mechanism. The anti-seepage connection mechanism includes:

[0032] The annular base plate 3 is a circular plate-shaped structure;

[0033] A plug-in cavity structure, which is two groups symmetrically arranged on both sides of the annular base plate 3, is used to insert the ends of the first pipe 1 and the second pipe 2 in the axial direction and connect the first pipe 1 and the second pipe 2 to each other. This is equivalent to connecting two adjacent groups of water supply and drainage pipes through the plug-in cavity structure to achieve pipeline laying. In addition, this connection method can avoid deviation or misalignment of the connection between the pipes, effectively improve the structural stability of the two adjacent groups of water supply and drainage pipes, and further avoid the risk of leakage in the water supply and drainage pipes used in municipal construction; and

[0034] Sealing structure: A sealing structure is provided inside each group of plug-in cavity structures to seal the two groups of plug-in cavity structures with the first pipe 1 and the second pipe 2 respectively. The sealing structure realizes the anti-seepage treatment of the water supply and drainage pipes.

[0035] Furthermore, the plug-in cavity structure includes an inner sleeve 4 and an outer sleeve 5, the inner sleeve 4 is coaxially arranged inside the outer sleeve 5, and the inner sleeve 4 and the outer sleeve 5 are coaxially connected to the side surface of the annular base plate 3, and an inner cavity for inserting the first pipe 1 or the second pipe 2 is reserved between the inner sleeve 4 and the outer sleeve 5, so that the first pipe 1 or the second pipe 2 can be connected by inserting into the inner cavity reserved between the inner sleeve 4 and the outer sleeve 5, wherein this cavity structure is equivalent to a more stable plug-in structure, which can effectively resist radial misalignment or offset between the pipe and the inner sleeve 4 and the outer sleeve 5.

[0036] Furthermore, the inner diameter of the inner sleeve 4 is equal to the inner diameter of the annular base plate 3 , and the outer diameter of the outer sleeve 5 is equal to the outer diameter of the annular base plate 3 , so that the inner and outer surfaces between the inner sleeve 4 and the outer sleeve 5 and the annular base plate 3 transition smoothly, making the inner and outer surfaces smoother.

[0037] Furthermore, the inner diameters of the first pipe 1 and the second pipe 2 are the same and are both larger than the outer diameter of the inner sleeve 4 so that the first pipe 1 and the second pipe 2 can be sleeved on the inner sleeve 4, and the inner diameter of the outer sleeve 5 is larger than the outer diameters of the first pipe 1 and the second pipe 2 so that the first pipe 1 or the second pipe 2 can be smoothly inserted.

[0038] Furthermore, the sealing structure includes:

[0039] an annular limiting groove 6, which is formed on the outer surface of the inner sleeve 4; and

[0040] The first sealing ring 7 is sleeved on the internal sleeve 4 and embedded in the annular limiting groove 6. The annular limiting groove 6 can prevent the first sealing ring 7 from being misplaced to stably achieve the sealing effect of the first sealing ring 7. When the first pipe 1 or the second pipe 2 is plugged into the internal sleeve 4, the first pipe 1 or the second pipe 2 and the internal sleeve 4 are sealed by the first sealing ring 7. Therefore, the adaptation between the inner diameter of the first pipe 1 or the second pipe 2 and the outer diameter of the internal sleeve 4 should allow the installation of the first sealing ring 7 to achieve sealing.

[0041] Furthermore, a second sealing ring 8 is provided on the inner sleeve 4, and the second sealing ring 8 is attached to the annular base plate 3, so that when the first pipe 1 or the second pipe 2 is inserted into the inner sleeve 4, the end of the first pipe 1 or the second pipe 2 can directly rest on the second sealing ring 8, thereby achieving a second seal to improve the sealing stability.

[0042] Furthermore, the sealing structure further comprises:

[0043] The arc-shaped fixed pressure plates 9 are arranged in a ring inside the inner cavity between the inner sleeve 4 and the outer sleeve 5. The center position of the outer arc surface of each set of arc-shaped fixed pressure plates 9 is vertically connected to a guide rod 10. The outer sleeve 5 is provided with a guide hole 11 for the guide rod 10 to extend from the inside. The guide rod 10 slides in the guide hole 11 to guide the arc-shaped fixed pressure plates 9 when they move relative to the pipeline, and also makes the arc-shaped fixed pressure plates 9 more accurate and stable in terms of compressing the pipeline; and

[0044] The tightening bolt 12 is driven from the outside of the outer sleeve 5 and extends into the inside of the outer sleeve 5 to tighten against the outer curved surface of the arc-shaped fixed pressure plate 9.

[0045] Specifically, the multiple groups of arc-shaped fixed pressure plates 9 distributed in the circumferential direction can fully press against the outer diameter of the pipe for fixation, and then push the arc-shaped fixed pressure plate 9 through the tightening bolts 12 to press the arc-shaped fixed pressure plate 9 on the water supply and drainage pipe to fix the pipe, thereby making the sealing structure more stable and less prone to dislocation.

[0046] Furthermore, multiple sets of tightening bolts 12 are provided at each set of arc-shaped fixed pressure plates 9 to tighten the arc-shaped fixed pressure plates 9 against the outer wall of the first pipe 1 or the second pipe 2. The multiple sets of tightening bolts 12 can be evenly distributed at the edge positions of the arc-shaped fixed pressure plates 9 to more evenly press the arc-shaped fixed pressure plates 9 against the pipes for fixation.

[0047] To sum up, this device connects two adjacent groups of water supply and drainage pipes through an anti-seepage connection mechanism and connects the pipes to realize the laying of water supply and drainage pipes and achieves a sealed connection at the same time. The anti-seepage connection mechanism can effectively improve the structural stability of the two adjacent groups of water supply and drainage pipes, reduce the occurrence of deviation or misalignment between pipes, and further avoid the risk of leakage of water supply and drainage pipes used in municipal construction.

[0048] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
