Description

Technical Field

[0001] The present application relates to an online plugging structure for a damaged pipeline. Background Art

[0002] Water pipelines can be divided into two categories: main pipelines and secondary pipelines. Main pipelines are generally made of PCCP pipes, i.e. prestressed concrete cylinder pipes. In addition to structural damage, this type of pipeline is generally damaged locally. After local damage occurs, it is impossible to perform local welding reinforcement treatment. Local sealing is now mostly used for treatment. However, this method can only reduce the leakage rate and has poor durability. Therefore, it is necessary to improve the repair structure of this type of pipeline to meet the requirements of online sealing, durability, and good sealing effect. Utility Model Content

[0003] To address the aforementioned issues, the present application proposes an online plugging structure for damaged pipes, comprising a wooden stake wedged into the damaged portion, with the top of the stake positioned so as to expose the damaged pipe. A coupling is disposed on the outside of the stake, with the top of the stake abutting the outside of the coupling. A fixed gap is formed between the inside of the coupling, the periphery of the wooden stake, and the outside of the damaged pipe, and a quick-drying cement layer is disposed within the fixed gap. The present application performs preliminary plugging by wedging the wooden stake into the damaged pipe, then performs overall plugging with the coupling, and then supplements the quick-drying cement layer, thereby achieving bonding, fixing, and sealing, and exhibiting excellent durability.

[0004] Preferably, the sleeve coupling comprises two semicircular plates arranged opposite to each other, side connecting plates are respectively arranged on both sides of the semicircular plates, and a plurality of fastening bolts are arranged between the side connecting plates.

[0005] Preferably, side sealing rubber strips are provided between the side connecting plates; end sealing rubber strips are provided at both ends of the semicircular plates; and guide slits are provided on the two semicircular plates, and the two guide slits are symmetrically arranged relative to the axis of the damaged pipe. The present application uses the guide slits to allow quick-drying cement to flow into the inner side of the sleeve, the periphery of the wooden pile, the outer side of the damaged pipe, and the fixed gap formed between the side sealing rubber strips and the end sealing rubber strips, thereby stably forming a quick-drying cement layer. The guide slit at the bottom needs to be sealed, and the introduction is carried out in the upper guide slit. Of course, in the early stage, the introduction can be accelerated by a non-sealed method, and then the closed introduction can be carried out in the later stage.

[0006] Preferably, the guide slit is a long strip through hole, and the guide slit is arranged along the axial direction of the damaged pipe.

[0007] Preferably, end annular plates are respectively provided on both sides of the semicircular plate, and a plurality of abutment plates are provided between the end annular plates, and the bottoms of the abutment plates are fixedly connected to the surfaces of the semicircular plates.

[0008] Preferably, the end annular plate is provided with a plurality of transverse bolt holes, in which transverse connecting bolts are provided. The present application can form an expandable sleeve collar by using the end annular plate and the transverse bolt holes. When a sleeve collar cannot cover a damaged part, the sleeve collar can be expanded in the length direction by using this expansion connection method, which is easy to assemble and highly reliable.

[0009] Preferably, the number of the sleeve collars is not less than two, and the connected sleeve collars are fixedly connected by transverse connecting bolts.

[0010] Preferably, a positioning groove is provided on the end annular plate.

[0011] Preferably, the semicircular plate is further provided with a plurality of reinforcing ribs.

[0012] This application can bring the following beneficial effects:

[0013] 1. This application performs preliminary sealing by wedging wooden stakes into the damaged pipe, then uses a coupling to seal the entire pipe, and then assists with the setting of a quick-drying cement layer, which can play the role of bonding, fixing and sealing, and has very good durability.

[0014] 2. The present application uses the guide seam to flow the quick-drying cement into the inner side of the sleeve, the periphery of the wooden pile, the outer side of the damaged pipe, and the fixed gap formed between the side sealing rubber strip and the end sealing rubber strip, thereby stably forming a quick-drying cement layer.

[0015] 3. The present application can form an expandable sleeve collar through the end ring plate and the transverse bolt hole. When one sleeve collar cannot cover the damaged part, the sleeve collar can be expanded in the length direction through this expansion connection method, which is easy to assemble and has high reliability.
