Description

Technical Field

[0001] The utility model belongs to the technical field of pipe culvert connection, and in particular relates to a pipe culvert connection structure. Background Art

[0002] Flange is a traditional connection component of pipe culvert. The flange is welded to the end of the pipe culvert and the two flanges are fixed by bolts to achieve the connection of the pipe culvert section. Figure 1 As shown, the two pipes 1 are connected and assembled via a flange 2.

[0003] The main function of oily packing (also called oil-immersed packing or oil-immersed asbestos packing) in flange-connected pipes is to provide a sealing effect. It fills the gap in the flange connection and forms a seal by compression to prevent leakage of fluid or gas in the pipe. However, when installing waterproof oily packing 3 between two flange surfaces of a large culvert, the oily packing 3 often falls off inwards. The light is poor and it is inconvenient for workers to enter the culvert for construction. It is extremely difficult to install and it is difficult to achieve a waterproof effect. In addition, the construction is inconvenient. Utility Model Content

[0004] Based on the problems mentioned in the above background technology, the utility model provides a pipe culvert connection structure.

[0005] The technical solution adopted by the utility model is as follows: a pipe culvert connection structure, including a first connecting pipe and an oily packing, the end of the first connecting pipe is inserted into the end of the second connecting pipe; the oily packing is arranged on the outer periphery of the first connecting pipe close to the end of the second connecting pipe; a connecting assembly is arranged outside the first connecting pipe and the second connecting pipe for fixing.

[0006] Furthermore, the connection assembly includes a second flange plate arranged at the end of the second connection pipe, a first flange plate is arranged on the outer sleeve of the first connection pipe, and the first flange plate is connected to the second flange plate.

[0007] Furthermore, the oily packing is located between the first flange and the second flange.

[0008] Furthermore, the second flange is welded to the second connecting pipe, and the first flange is welded to the first connecting pipe.

[0009] Furthermore, the first flange is connected to the second flange by bolts.

[0010] Furthermore, the first connecting pipe and the second connecting pipe are corrugated pipes.

[0011] Beneficial effects of the utility model:

[0012] By sinking the first connecting pipe into the second connecting pipe, the oily packing is arranged outside the first connecting pipe and at the end of the second connecting pipe. On the one hand, the obstruction of the first connecting pipe will not cause it to fall off into the culvert like the traditional flange connection method; on the other hand, the circle is located against the end of the second connecting pipe to achieve a water-tight effect on the connection; it is convenient for waterproofing and preventing the oily packing from falling off, and it is also convenient for workers to install and construct.

[0017] Pipe 1, flange 2, oily packing 3, first connecting pipe 4, second connecting pipe 5, second flange 6, first flange 7, bolt 8. DETAILED DESCRIPTION

[0018] like Figure 1-2 As shown, a pipe culvert connection structure includes a first connecting pipe 4 and an oily packing 3, wherein the end of the first connecting pipe 4 is inserted into the end of the second connecting pipe 5; the oily packing 3 is arranged around the outer periphery of the first connecting pipe 4 close to the end of the second connecting pipe 5; a connecting assembly is arranged outside the first connecting pipe 4 and the second connecting pipe 5 for fixing.

[0019] By adopting the above technical solution, the oily packing 3 is arranged outside the first connecting pipe 4 by sinking the first connecting pipe 4 into the second connecting pipe 5. On the one hand, it will not fall off into the culvert like the traditional flange connection method; on the other hand, the circle position abuts against the end of the second connecting pipe 5 to achieve the water-tight effect on the connection; it is convenient for waterproofing and preventing the oily packing 3 from falling off, and it is also convenient for workers to install and construct.

[0020] As a preferred solution, the connection assembly includes a second flange 6 disposed at the end of the second connection pipe 5, a first flange 7 is disposed on the outer sleeve of the first connection pipe 4, and the first flange 7 is connected to the second flange 6. The flange connection method is convenient for connection and easy construction.

[0021] As a preferred solution, the oily packing 3 is located between the first flange 7 and the second flange 6. The installation position of the oily packing 3 has a good waterproof effect, is stable in installation, and is easy to install.

[0022] As a preferred solution, the second flange 6 is welded to the second connecting pipe 5, and the first flange 7 is welded to the first connecting pipe 4. Welding ensures the stability of the connection.

[0023] As a preferred solution, the first flange 7 is connected to the second flange by bolts 8. The bolts 8 are convenient and stable.

[0024] As a preferred solution, the first connecting pipe 4 and the second connecting pipe 5 are corrugated pipes.

[0025] The utility model is described in detail above. The description of the specific embodiments is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
