Description

Technical Field

[0001] The utility model relates to the field of pipeline connection tools, in particular to a device for improving the grouting density of a pipeline interface. Background Art

[0002] Pipes are divided into various materials. Generally, metal pipes can be connected by screws and other methods, while cement pipes are connected by interface grouting. Existing pipes are generally composed of multiple long or short pipes. The connection ports are generally made of cement grouting paste at the interface, and the interface can be sealed after natural air drying. However, this method also has many disadvantages. Since there is no support at the grouting point between the pipes, multiple external wooden boards are generally used to fit at the interface, and then grouting is performed. This method has multiple large and small gaps during grouting, and cement is easy to flow into the gaps instead of being squeezed compactly. Therefore, the density of the grouting is insufficient. As the use time increases, the cement is prone to loosening, causing internal leakage.

[0003] Therefore, the existing pipeline interface connection needs to be further improved. Utility Model Content

[0004] In view of the above-mentioned prior art, the technology to be achieved by the utility model is: to make the density of the pipe connection better after grouting.

[0007] Furthermore, the installation structure in the utility model includes a groove arranged on the annular cross-section of the sleeve one and the sleeve two, and the groove can be sleeved on the pipe mouth. A plurality of deformable locking patches are arranged on the periphery of the annular cross-section of the sleeve one and the sleeve two, and the locking patches can be connected to the outer wall of the pipe by screws.

[0008] Furthermore, the sealing fitting in the utility model includes a sealing inner layer arranged on the first sleeve and a sealing outer layer arranged on the second sleeve.

[0009] Furthermore, in the utility model, a sealing convex edge is arranged on the front end outer wall of the sealing inner layer, and an embedding groove is arranged on the rear end outer wall of the sealing inner layer.

[0010] Furthermore, the sealing outer layer in the utility model is formed by a plurality of arc sheets arranged in a ring shape, and a fillet is arranged at the rear end of the inner wall of the sealing outer layer, and the fillet can be connected to the embedding groove.

[0011] Furthermore, the outer diameter of the sealing convex edge in the utility model is the same as the inner diameter of the sealing outer layer.

[0012] Furthermore, the wrapping layer in the utility model can be grouted with cement in the space between the outer wall of the sealed outer layer and the space between the first sleeve and the second sleeve.

[0013] Furthermore, an outer enclosure that can shield the wrapping layer is provided between the first and second sleeves in the utility model. The outer enclosure is sheet-shaped and can be fixed into a ring shape by screws.

[0014] In summary, the beneficial effects of the present invention compared with the prior art are as follows:
