Description

Technical Field

[0001] The present application relates to a large-diameter pipeline connection structure. Background Art

[0002] When transferring large amounts of water continuously, two solutions are generally adopted, one is the open channel setting method, and the other is the pipeline setting method. The main problem with the open channel setting method is that it occupies a large area and has high costs during construction, but the maintenance and use costs are high, and even ancillary landscapes can be built; the main problem with the pipeline setting method is that the maintenance and use costs are high, and it is not easy to repair when damaged. This type of pipeline uses a large-diameter prestressed steel cylinder concrete pipe. This type of pipeline is generally connected in the form of plug-in sealing, and is generally supplemented by welding connection. The convenience of operation is poor. If there is a problem with the sealing component at the connection, it is generally impossible to disassemble it, and only completely destructive repairs can be carried out. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a large-caliber pipeline connection structure, including two relatively arranged semicircular outer shells, a sealing ring groove is arranged inside the semicircular outer shell, a sealing ring is arranged in the sealing ring groove, and outer positioning edges are arranged on both sides of the semicircular outer shell to be clamped with the positioning groove arranged on the pipeline; connecting plates are arranged at both ends of the semicircular outer shell, and fastening bolts are arranged between the connecting plates of the two relatively arranged semicircular outer shells. The present application uses the semicircular outer shell to complete the connection and positioning of the pipeline by means of the sealing ring and the outer positioning edge, which ensures the internal sealing while also ensuring the maintainability of the renovation, and reduces the maintenance and use costs of the pipeline to a certain extent.

[0004] Preferably, the sealing ring includes a sealing bottom plate abutting against the sealing ring groove, and L-shaped ears are provided on both sides of the sealing bottom plate. The L-shaped ears are bent relative to the sealing bottom plate and abut against the outer wall of the pipeline.

[0005] Preferably, an abutment ring is provided on one side of the middle of the sealing bottom plate facing the pipe, and the abutment ring is squeezed and arranged between the two pipes. The present application adopts an abutment ring for preliminary installation and positioning. During the specific installation, the abutment ring does not penetrate into the pipe, but mainly plays a role in positioning and avoiding the unstable position of the sealing ring. Of course, it can also play a role in supplementing the seal.

[0006] Preferably, the L-shaped ear comprises a vertically extending sealing plate connected to the sealing bottom plate, and an inwardly extending transversely extending sealing plate is arranged at the end of the vertically extending sealing plate.

[0007] Preferably, the thickness of the transversely extending sealing plate is gradually thinner.

[0008] Preferably, the connecting plate includes a plate body, bolt holes for fastening bolts to pass through are arranged on the plate body, a buffer edge is arranged above the plate body, and a buffer cavity is arranged in the middle of the buffer edge. The present application improves the structure of the connecting plate, which can avoid loosening of the connecting bolts due to vibration during use, ensure the clamping force inside, and then ensure the safety, stability and sealing of the overall structure.

[0009] Preferably, a buffer slope is provided on the outer side of the buffer edge.

[0010] Preferably, reinforcing ribs are respectively arranged on the outside of both sides of the semicircular outer shell.

[0011] This application can bring the following beneficial effects:

[0012] 1. The present application adopts a semicircular outer shell to complete the connection and positioning of the pipeline by means of a sealing ring and an outer positioning edge, which ensures the internal sealing while also ensuring the maintainability of the renovation, thereby reducing the maintenance and use costs of the pipeline to a certain extent.

[0013] 2. This application uses an abutment ring for preliminary installation and positioning. During the specific installation, the abutment ring does not penetrate into the pipe, but mainly plays a role in positioning and avoiding unstable setting of the sealing ring. Of course, it can also play a certain role in supplementing the sealing.

[0014] 3. The present application improves the structure of the connecting plate, which can prevent the loosening of the connecting bolts due to vibration during use, ensure the internal clamping force, and then ensure the safety, stability and sealing of the overall structure.
