Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connectors, and particularly relates to an anti-seepage structure for a drainage pipeline interface. Background Art

[0002] The drainage pipeline system is a core component of urban infrastructure, responsible for collecting, transporting, and discharging domestic sewage and industrial wastewater. As a key component in the drainage pipeline system, the interface device connects adjacent pipeline segments, ensures the sealing of the pipeline, and prevents sewage from leaking. The drainage pipeline interface device, as a key component in the drainage pipeline system, directly affects the sealing performance and service life of the drainage pipeline.

[0003] In the design of existing municipal sewage pipes, a flange structure is provided at each end of the sewage pipe, and a clamping groove is provided at the center of the flange for placing a rubber ring. During docking, a rubber gasket is arranged between the clamping grooves inside the two flanges. However, due to the rubber gasket being in a long-term compressed and stressed state, the internal long-term stress causes the rubber gasket to deform or even break, resulting in gaps on the outer wall of the rubber gasket and causing leakage, making the flange structure less tightly connected, causing water seepage and leakage in the pipeline, and increasing the moisture content of the roadbed and causing roadbed settlement. Summary of the Invention

[0004] To overcome the deficiencies of the prior art, the utility model provides an anti-seepage structure for a drainage pipeline interface, which improves the sealing effect of the rubber gasket on the pipe body and also improves the structural strength of the pipeline.

[0005] To achieve the above object, the anti-seepage structure for a drainage pipeline interface of the utility model includes a first pipe body and a second pipe body. A rubber gasket assembly is arranged between the first pipe body and the second pipe body. The rubber gasket assembly includes a first rubber gasket assembly, a second rubber gasket assembly, and a middle rubber gasket. The first rubber gasket assembly is connected to the end of the first pipe body, the second rubber gasket assembly is connected to the end of the second pipe body, and the first rubber gasket assembly and the second rubber gasket assembly are respectively connected to the middle rubber gasket.

[0006] Further, the middle rubber gasket is a tubular structure with openings at both ends, and a positioning ring extending radially inward is arranged on the inner wall of the middle section of the middle rubber gasket.

[0007] Further, the first rubber gasket assembly includes a first inner rubber gasket and a first outer rubber gasket. The first outer rubber gasket is sleeved outside the first inner rubber gasket, and the inner wall of the first outer rubber gasket does not contact the outer wall of the first inner rubber gasket. The ends of the first inner rubber gasket and the first outer rubber gasket both abut against the positioning ring, and the first pipe body is arranged in the cavity formed by the first inner rubber gasket, the first outer rubber gasket, and the positioning ring.

By inserting the first pipe body into the cavity formed by the first outer rubber pad, the middle rubber pad and the first inner rubber pad, the rubber pads are tightly abutted against the pipe body, forming an impermeable sealed cavity between the rubber pads and the pipe body, and preventing the internal sewage from flowing out through the gap between the rubber pads and the pipe body through the sealed cavity.

[0009] Further, the second rubber pad assembly includes a second inner rubber pad and a second outer rubber pad.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solution of the present utility model will be described more clearly and completely below in conjunction with the accompanying drawings and through the description of the preferred embodiments of the present utility model.

[0018] As Figure 1 and Figure 2 shown, the anti-seepage structure of the drainage pipe interface in the preferred embodiment of the present utility model includes a first pipe body 1 and a second pipe body 2. A rubber pad assembly is provided between the first pipe body 1 and the second pipe body 2. The rubber pad assembly includes a first rubber pad assembly, a second rubber pad assembly and a middle rubber pad 5. The first rubber pad assembly is connected to the end of the first pipe body 1, the second rubber pad assembly is connected to the end of the second pipe body 2, and the first rubber pad assembly and the second rubber pad assembly are respectively connected to the middle rubber pad 5.

[0019] As Figure 2 shown, the middle rubber pad 5 is a tubular structure with openings at both ends. A positioning ring 51 extending radially inward is provided on the inner wall of the middle section of the middle rubber pad 5.

[0020] As Figure 1 and Figure 2 shown, the first rubber pad assembly includes a first inner rubber pad 31 and a first outer rubber pad 32. The first outer rubber pad 32 is sleeved outside the first inner rubber pad 31. The inner wall of the first outer rubber pad 32 does not contact the outer wall of the first inner rubber pad 31. The ends of the first inner rubber pad 31 and the first outer rubber pad 32 both abut against the positioning ring 51. The first pipe body 1 is arranged in the cavity formed by the first inner rubber pad 31, the first outer rubber pad 32 and the positioning ring 51. The outer wall of the first inner rubber pad 31 abuts against the inner wall of the first pipe body 1, the inner wall of the first outer rubber pad 32 abuts against the outer wall of the first pipe body 1, and the outer wall of the first outer rubber pad 32 abuts against the inner wall of the middle rubber pad 5.

[0021] As Figure 2 shown, the second rubber pad assembly includes a second inner rubber pad 41 and a second outer rubber pad 42. The second outer rubber pad 42 is sleeved outside the second inner rubber pad 41. The inner wall of the second outer rubber pad 42 does not contact the outer wall of the second inner rubber pad 41. The ends of the second inner rubber pad 41 and the second outer rubber pad 42 both abut against the positioning ring 51. The second pipe body 2 is arranged in the cavity formed by the second inner rubber pad 41, the second outer rubber pad 42 and the positioning ring 51. The outer wall of the second inner rubber pad 41 abuts against the inner wall of the second pipe body 2, the inner wall of the second outer rubber pad 42 abuts against the outer wall of the second pipe body 2, and the outer wall of the second outer rubber pad 42 abuts against the inner wall of the middle rubber pad 5.

[0022] As Figure 1As shown, the middle rubber pad 5 is provided with a break opening extending along its axial direction. Locking blocks 52 are respectively provided at both ends of the middle rubber pad 5 close to the break opening. A buckle 6 is provided on the locking block 52, and a locking opening 61 matching the two locking blocks 52 is provided on the buckle 6. Both ends of the middle rubber pad 5 close to the break opening are in interference fit, so as to prevent sewage from leaking out of the middle rubber pad 5.

[0023] By inserting the pipe body into the cavity formed by the outer rubber pad, the middle rubber pad and the inner rubber pad, each rubber pad is tightly abutted against the pipe body, so as to form an impermeable sealed cavity between the rubber pad and the pipe body. The internal sewage is prevented from flowing out through the gap between the rubber pad and the pipe body by the sealed cavity. Even when the rubber pad cracks, under the action of the sewage pressure, the pipe body continues to approach the pipe body, and a self-sealing effect is generated by the rubber pad. The cracked rubber pads cannot be separated under the action of the mutual pressure between the pipe bodies, so that the rubber pad continues to provide a sealing function even in the case of cracking. This design increases the sealing performance and durability of the structure by optimizing the structure of the pipe interface, and can effectively prevent sewage from leaking from the pipe interface.
