Description

Technical Field

[0001] This utility model relates to the field of municipal pipeline repair technology, specifically to a municipal pipeline repair device. Background Technology

[0002] Municipal facilities refer to public facilities constructed with funds from the government, legal entities, or citizens. They generally refer to various buildings, structures, and equipment within a planned area. This includes urban roads, urban rail transit, water supply, drainage, gas supply, heating, landscaping, environmental sanitation, street lighting, industrial waste, medical waste, and domestic waste treatment equipment, sites, and other facilities and ancillary facilities.

[0003] Municipal pipelines are a type of municipal facility. When municipal pipelines are damaged, they need to be repaired. The traditional repair method is to remove the foundation of the damaged area, enlarge the damaged area, remove the debris blocking the municipal pipeline, and then use a split joint to directly fix the municipal pipeline at the damaged area. However, because there is a certain distance between the inner wall of the municipal pipeline and the inner wall of the split joint, debris can easily block the pipeline, causing further damage. This method needs to be improved. Utility Model Content

[0004] (I) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to overcome the above difficulties and provide a municipal pipeline repair device that repairs the inner wall of a pipeline at zero distance from the inner wall of the municipal pipeline and prevents damage to the repaired area.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a municipal pipeline repair device, including a repair pipe disposed between municipal pipelines, wherein the repair pipe includes symmetrically arranged and mutually cooperating semi-circular pipes;

[0008] Both ends of the semicircular pipe are provided with semicircular notches that engage with the outside of the municipal pipeline.

[0009] As an improvement, the semicircular pipe is provided with ears on both sides, and several bolts are evenly provided on the ears to make the semicircular pipes fit together and seal.

[0010] As an improvement, a sealing strip is provided on the ear, and the bolt passes through the sealing strip.

[0011] As an improvement, several arc-shaped sealing strips are sequentially adhered inside the semi-circular notch, and the arc-shaped sealing strips are set to fit the outer side of the municipal pipeline.

[0012] As an improvement, the inner diameter of the repaired pipe is the same as that of the municipal pipe.

[0013] (III) Beneficial Effects

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] 1. The inner diameter of the repaired pipe is the same as that of the municipal pipe, and there is no gap between the repaired pipe and the inner wall of the municipal pipe, so debris will not cause blockage.

[0016] 2. The repair pipe consists of two semi-circular pipes, which are fastened together by bolts to facilitate the installation of the repair pipe;

[0017] 3. The semi-circular notch can be engaged with the outside of the municipal pipeline. The arc-shaped sealing strip is detachable. The number of arc-shaped sealing strips can be adjusted according to the outer diameter of the municipal pipeline so that the semi-circular notch can be tightly engaged with the outside of the municipal pipeline.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example

[0024] Combined with appendix Figure 1-4 A municipal pipeline repair device includes a repair pipe 1 disposed between municipal pipelines, wherein the repair pipe 1 includes symmetrically arranged and mutually cooperating semi-circular pipes 2.

[0025] The inner diameter of the repair pipe 1 is the same as that of the municipal pipe. There is no gap between the inner wall of the repair pipe 1 and the inner wall of the municipal pipe, which allows water to flow more smoothly and prevents debris in the water from clogging the pipe again.

[0026] Both ends of the semicircular pipe 2 are provided with semicircular notches 3 that engage with the outside of the municipal pipe.

[0027] Both sides of the semicircular pipe 2 are provided with ears 4, and several bolts 5 are evenly provided on the ears 4 to make the semicircular pipe 2 fit together and seal.

[0028] The ear part 4 is provided with a sealing strip 6, and the bolt 5 is installed through the sealing strip 6.

[0029] Several arc-shaped sealing strips 7 are sequentially adhered inside the semi-circular notch 3. The arc-shaped sealing strips 7 are set to fit the outer side of the municipal pipeline. The number of arc-shaped sealing strips 7 can be adjusted according to the different outer diameters of the municipal pipeline so that the semi-circular notch 3 can be locked onto the municipal pipeline.

[0030] In the specific implementation of this utility model, the damaged part of the municipal pipeline is located, the foundation of the municipal pipeline is removed, the damaged municipal pipeline is cut, so that the repair pipe 1 can be fitted between the municipal pipelines, and the semi-circular notch 3 can be fitted on the outside of the municipal pipeline. Then, the debris inside the municipal pipeline is removed, the outer end of the municipal pipeline is ground to remove impurities, and according to the size of the outer diameter of the municipal pipeline, the excess arc-shaped sealing strip 7 on the repair pipe 1 is torn off. The semi-circular pipe 2 is placed between the municipal pipelines, and the semi-circular pipe 2 is fastened with bolts 5 so that the semi-circular pipes 2 are close to each other, the sealing strips 6 are attached to each other, and the arc-shaped sealing strip 7 in the semi-circular notch 3 is attached to the outside of the municipal pipeline.

[0031] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, alterations, deletions of some features, additions of features, or recombinations of features to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
