Description

Technical Field

[0001] The utility model relates to the technical field of underwater water pipe connection, in particular to a special-shaped half connection structure for an underwater gravity flow pipeline. Background Technique

[0002] With the increasing use time of urban pipe networks, the utilization rate of pipelines is high. In the design of underwater construction and installation of large-diameter water intake pipelines, the deviation of multi-process jacking pipes, overhead pipelines, and the docking of immersed pipes is not considered. Due to the deviation of the pipeline construction axis, the pipelines cannot be docked.

[0003] However, the existing special-shaped half connection structure for underwater gravity flow pipelines has the following problems in the process of use: when the traditional jacking pipe jacks forward, the pipeline axis deviation will occur due to the uneven soil structure, and the pile position deviation will also occur when the underwater pipe section is driven; so when docking large-diameter underwater pipelines, the axes of the two pipelines will basically deviate, and thus cannot be docked, and the sealing effect is not good, and pipeline leakage is likely to occur. Content of the Utility Model

[0004] The purpose of the utility model is to provide a special-shaped half connection structure for an underwater gravity flow pipeline to solve the related problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a special-shaped half connection structure for an underwater gravity flow pipeline, including a special-shaped connection pipeline, an external connection block, and a reinforcing rib. The outer wall of the special-shaped connection pipeline is welded with an external connection block, and a reinforcing rib welded to the special-shaped connection pipeline is welded on one side of the external connection block. Sealing mechanisms for waterproof sealing are arranged at the top and bottom of the special-shaped connection pipeline. The sides of the special-shaped connection pipeline and the external connection block are arrow-shaped.

[0006] In the special-shaped half connection structure for an underwater gravity flow pipeline provided by this technical scheme, the sealing mechanism includes a sealing groove and a sealing rubber tube. A sealing groove is opened on the inner wall of the special-shaped connection pipeline, and a sealing rubber tube is arranged on the inner wall of the sealing groove.

[0007] In the special-shaped half connection structure for an underwater gravity flow pipeline provided by this technical scheme, an inner hole is opened on the inner wall of the sealing rubber tube.

[0008] In the special-shaped half connection structure for an underwater gravity flow pipeline provided by this technical scheme, an installation hole is opened on the inner wall of the external connection block.

[0009] In the special-shaped half connection structure for an underwater gravity flow pipeline provided by this technical scheme, a sealing gasket is arranged on the inner wall of the special-shaped connection pipeline.

[0010] Compared with the prior art, the utility model provides a special-shaped half-coupling connection structure for an underwater gravity pipeline, which has the following beneficial effects:

[0011] 1. In the utility model, the middle of the flat semi-coupling steel sleeve is processed into a convex shape to accommodate pipeline errors, and it is transformed into a special-shaped connecting pipeline, so that it can be quickly butted when there is an axial deviation of the pipeline, and there will be no shutdown due to the axial error of the pipeline, saving the equipment usage shift fee and the underwater construction operation fee of divers, and reducing the pipeline installation cost of the enterprise.

[0012] 2. In the utility model, the sealing rubber tube is located at the sealing groove, and the two side pipelines are inserted into the special-shaped connecting pipeline. Then, by extruding the sealing rubber tube and the sealing gasket, under the sealing action of the sealing rubber tube and the sealing gasket, it is convenient to seal and connect the two groups of water pipes.

[0019] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0020] Example 1, as Figure 1-2As shown in the figure, the utility model provides a technical solution: a special-shaped Hough connection structure for an underwater gravity pipeline, which includes a special-shaped connection pipeline 1, an external connection block 2 and a reinforcing rib 3. The external connection block 2 is welded to the outer wall of the special-shaped connection pipeline 1. Sealing mechanisms for waterproof sealing are arranged at both the top and bottom of the special-shaped connection pipeline 1. The sealing mechanism includes a sealing groove 5 and a sealing rubber tube 6. The sealing groove 5 is formed on the inner wall of the special-shaped connection pipeline 1, and the sealing rubber tube 6 is arranged on the inner wall of the sealing groove 5. An inner hole 601 is formed on the inner wall of the sealing rubber tube 6. A sealing gasket 7 is arranged on the inner wall of the special-shaped connection pipeline 1. When the sealing rubber tube 6 is at the sealing groove 5 and the two side pipelines are inserted into the special-shaped connection pipeline 1, the sealing rubber tube 6 and the sealing gasket 7 can be squeezed, and under the sealing action of the sealing rubber tube 6 and the sealing gasket 7, it is convenient to seal and connect the two groups of water pipes.

[0021] Example 2, as Figure 1-5 As shown in the figure, the utility model provides a technical solution: a special-shaped Hough connection structure for an underwater gravity pipeline, which includes a reinforcing rib 3 welded to one side of the external connection block 2 and welded to the special-shaped connection pipeline 1. The sides of the special-shaped connection pipeline 1 and the external connection block 2 are arrow-shaped. An installation hole 4 is formed on the inner wall of the external connection block 2. When the large-diameter water intake pipeline is constructed and installed underwater, it is easy to have deviations in the docking of the jacking pipe, the overhead pipe and the immersed pipe, resulting in the inability to dock between the pipes. Since the shape of the special-shaped connection pipeline 1 is arrow-shaped, when there is a deviation in the construction axis of the jacking pipe and the overhead pipeline, the special-shaped connection pipeline 1 can have a large tolerance for sealing docking.

[0022] Working principle: First, the middle of the flat semi-closed steel sleeve is processed into a convex shape to accommodate the pipeline error, and it is transformed into a special-shaped Hough joint, so that it can be quickly docked when the pipeline axis deviates, and there will be no shutdown due to the pipeline axis error, saving the equipment use shift fee and the underwater construction operation fee of divers, and reducing the pipeline installation cost of the enterprise. The maximum pipeline misalignment of this structure is 20CM, and the gap is just right. The operator passes the bolt through the two installation holes 4, which is convenient for quickly installing and fixing the special-shaped connection pipeline 1. When the sealing rubber tube 6 is at the sealing groove 5 and the two side pipelines are inserted into the special-shaped connection pipeline 1, the sealing rubber tube 6 and the sealing gasket 7 can be squeezed, and under the sealing action of the sealing rubber tube 6 and the sealing gasket 7, it is convenient to seal and connect the two groups of water pipes.

[0023] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Any simple modification or equivalent replacement of the technical solution of the utility model by those of ordinary skill in the art does not depart from the essence and scope of the technical solution of the utility model.
