Description

Technical Field

[0001] This utility model relates to the field of municipal facilities, and in particular to a municipal drainage pipe structure. Background Technology

[0002] Municipal drainage facilities refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater. Municipal drainage pipes are an important part of municipal drainage facilities and can be classified by material into concrete drainage pipes, PVC drainage pipes, iron drainage pipes, etc.

[0003] Currently, concrete municipal drainage pipes in related technologies are usually prefabricated. When laying municipal drainage pipes, multiple drainage pipe sections are inserted and connected in sequence to form a longer drainage pipe structure.

[0004] However, in related technologies, the sealing effect between two adjacent drainage pipes in municipal drainage pipes is relatively poor, and sewage can easily seep out through the gaps between the two adjacent drainage pipes, thereby affecting the stability of the municipal drainage pipe structure and needs to be improved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a municipal drainage pipe structure that improves the sealing effect between two adjacent drainage pipes, ensures the overall sealing effect of the municipal drainage pipe, and thus ensures the stability of the municipal drainage pipe structure in use.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a municipal drainage pipe structure, including multiple drainage pipes, each drainage pipe having an integrally formed insertion ring at one end and a stepped groove at the other end, the insertion ring being arranged along the circumference of the drainage pipe, and the insertion ring being able to be tightly inserted into the corresponding stepped groove.

[0007] Each of the plug-in rings has an elastic sealing ring fixedly connected to its end face. The sealing ring is arranged along the circumference of the plug-in ring. Each stepped groove has an annular sealing groove at its bottom, and the sealing ring can be tightly inserted into the corresponding sealing groove.

[0008] In a preferred embodiment, the present invention can be further configured such that: the sealing ring includes an annular sealing skeleton, the sealing skeleton is wrapped with an elastic sealing layer, the cross-section of the sealing skeleton is arched, and the arched end of the sealing skeleton is fixedly connected to the insertion ring;

[0009] When the sealing skeleton is inserted into the corresponding sealing groove, both ends of the sealing skeleton can expand outward under the action of the bottom of the sealing groove and abut tightly against the corresponding inner wall of the sealing groove.

[0010] In a preferred embodiment, the present invention can be further configured such that: the bottom of the sealing groove and the inner walls on both sides are respectively provided with elastic sealing sheets.

[0011] In a preferred embodiment, the present invention can be further configured such that: the outer diameter of the end of the plug ring away from the drain pipe is smaller than the outer diameter of the other end, and the outer sidewall of the plug ring forms a guide sealing slope, and the inner sidewall of the stepped groove matches the guide sealing slope.

[0012] In a preferred embodiment, the present invention can be further configured such that: one end of the drain pipe is fixedly connected to a plurality of positioning posts, and the other end is provided with a plurality of positioning grooves, and the positioning posts can be inserted and engaged with the corresponding positioning grooves to achieve limiting of two adjacent drain pipes after insertion.

[0013] In a preferred embodiment, the present invention can be further configured such that: a plurality of grouting holes are provided on the side of the drain pipe near the stepped groove, the plurality of grouting holes are arranged at equal intervals along the circumference of the drain pipe, and the plurality of grouting holes are respectively connected to the stepped groove.

[0014] In a preferred embodiment, the present invention can be further configured such that each of the grouting holes is provided with an elastic sealing plug.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By adding a sealing ring and sealing groove between two adjacent drainage pipes, the sealing effect between the two adjacent drainage pipes is effectively improved, thereby ensuring the overall sealing stability of the municipal drainage pipeline.

[0017] 2. When the sealing ring is inserted into the sealing groove, the two ends of the sealing skeleton expand outward under the action of the bottom of the sealing groove and abut tightly against the corresponding inner wall of the sealing groove, thereby improving the sealing effect by increasing the tightness between the sealing ring and the sealing groove.

[0018] 3. By using the positioning column and positioning groove together, the positioning is limited after the two adjacent drainage pipes are connected, reducing the risk of relative torsion between the two adjacent drainage pipes, improving connection stability, and thus improving the stability of municipal drainage pipelines.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1 , Figure 2 A municipal drainage pipe structure includes multiple drainage pipes 1. Each drainage pipe 1 has an integrally formed insertion ring 2 at one end and a stepped groove 3 at the other end. The insertion ring 2 is arranged along the circumference of the drainage pipe 1. When two drainage pipes 1 are connected, the insertion ring 2 can be tightly inserted and matched with the corresponding stepped groove 3, thereby realizing the connection of the two drainage pipes 1.

[0024] Reference Figure 1 , Figure 2 Each plug-in ring 2 has an elastic sealing ring 4 fixedly connected to its end face. The sealing ring 4 is arranged around the circumference of the plug-in ring 2. Each stepped groove 3 has an annular sealing groove 5 at its bottom. The sealing ring 4 can be tightly inserted into the corresponding sealing groove 5 to improve the sealing effect between two adjacent drain pipes 1.

[0025] Reference Figure 1 , Figure 2 The sealing ring 4 includes an annular sealing skeleton 41, on which an elastic sealing layer 42 is wrapped. The cross-section of the sealing skeleton 41 is arched, and the arched end of the sealing skeleton 41 is fixedly connected to the insertion ring 2. Elastic sealing sheets 6 are respectively provided on the bottom and inner walls of the sealing groove 5. When the sealing skeleton 41 is inserted into the corresponding sealing groove 5, both ends of the sealing skeleton 41 can expand outward under the action of the bottom of the sealing groove 5 and tightly abut against the sealing sheets 6 on the inner walls of the sealing groove 5 to improve the sealing effect.

[0026] In this embodiment, the sealing frame 41 is made of spring steel, and the sealing layer 42 and the sealing sheet 6 are made of elastic materials such as rubber and latex.

[0027] Reference Figure 1 , Figure 2 The outer diameter of the end of the insertion ring 2 furthest from the drain pipe 1 is smaller than the outer diameter of the other end, and the outer wall of the insertion ring 2 forms a guide sealing slope 7, with the inner wall of the stepped groove 3 matching the guide sealing slope 7. The guide sealing slope 7 serves both a guiding function, allowing the two drain pipes 1 to connect quickly, and the cooperation between the guide sealing slope 7 and the stepped groove 3 achieves a slope seal, further improving the sealing effect between the two drain pipes 1.

[0028] Reference Figure 1 , Figure 2 One end of the drain pipe 1 is fixedly connected with multiple positioning posts 8, and the other end is provided with multiple positioning grooves 9. When two drain pipes 1 are connected, the multiple positioning posts 8 are respectively inserted into the corresponding positioning grooves 9 to achieve the limiting of the two adjacent drain pipes 1 after insertion, prevent the drain pipes 1 from twisting relative to each other, and improve the connection stability.

[0029] Reference Figure 1 , Figure 2 Multiple grouting holes 10 are provided on the side of the drain pipe 1 near the stepped groove 3. The multiple grouting holes 10 are arranged at equal intervals along the circumference of the drain pipe 1, and the multiple grouting holes 10 are respectively connected to the stepped groove 3. At the same time, each grouting hole 10 is provided with an elastic sealing plug 11.

[0030] After the drainage pipe 1 is connected, the sealing plug 11 is pulled out, and then concrete grout is injected into the grouting hole 10. After the concrete grout has solidified, the connection between the two adjacent drainage pipes 1 can be realized, which can improve the connection stability of the two adjacent drainage pipes 1 and improve the sealing effect of the two adjacent drainage pipes 1.
