Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage pipelines, in particular to a municipal drainage pipeline. Background Art

[0002] Before discussing the design optimization of municipal drainage pipes, it is very important to understand the background technology and its shortcomings. The municipal drainage system is an important part of urban infrastructure, responsible for collecting and discharging urban rainwater and domestic sewage to prevent floods and maintain public health. However, the existing municipal drainage pipe system faces many challenges.

[0003] Structural fragility and lifespan issues: Traditional drainage pipes are mostly made of ordinary concrete or metal materials, which are susceptible to chemical corrosion and physical wear. For example, concrete pipes will gradually deteriorate in an acidic environment, and metal pipes may fail due to rust. These factors lead to the need for frequent maintenance or replacement of drainage pipes, which increases maintenance costs and affects the service life of the pipes.

[0004] Environmental impact and noise issues: Traditional drainage systems fail to fully consider heat and sound insulation issues, especially in densely populated areas, where noise during drainage and pipes being affected by external temperature are particularly prominent. This not only affects the quality of life of residents, but may also cause pipes to shrink and expand due to temperature differences, thus affecting their structural stability.

[0005] Difficulty in maintenance and replacement: Most existing drainage pipe systems were not designed with easy maintenance and replacement in mind. Once part of the pipe needs to be maintained or replaced, the entire process is often cumbersome and costly, especially for pipes buried deeper, which are more difficult to maintain and replace, requiring a lot of manpower and mechanical equipment.

[0006] Insufficient ability to cope with impact and external pressure: In extreme weather or unexpected situations, traditional pipelines may not be able to effectively disperse fluid impact and external pressure, and are prone to rupture or other forms of structural damage. Such damage not only requires immediate repair, but may also cause greater harm to the surrounding environment.

[0007] Therefore, this scheme especially proposes a municipal drainage pipeline to solve the above problems. Utility Model Content

[0008] In order to overcome the defects of the prior art, the purpose of the utility model is to provide a municipal drainage pipeline.

[0009] To achieve the above-mentioned purpose, the technical solution of the utility model is implemented as follows: a municipal drainage pipe comprises an external fixed pipe, a thermal insulation and sound insulation layer is arranged on the inner side of the external fixed pipe, a buffer layer is arranged on the inner side of the thermal insulation and sound insulation layer, an internal fixed pipe is arranged on the inner side of the buffer layer, a replaceable inner pipe is arranged on the inner side of the internal fixed pipe, a plurality of positioning guide grooves are evenly arranged on the inner wall of the internal fixed pipe and distributed along the length direction of the entire drainage pipe, a plurality of positioning convex strips are evenly arranged on the outer pipe wall of the replaceable inner pipe and distributed along the length direction of the entire drainage pipe, and a plurality of the positioning convex strips are correspondingly snapped into the inside of a plurality of the positioning guide grooves.

[0010] As a preferred technical solution of the utility model, the outer fixing tube and the inner fixing tube are both cast by concrete.

[0011] As a preferred technical solution of the present utility model, the thermal insulation and sound insulation layer is filled with a porous thermal insulation and sound insulation board material.

[0012] As a preferred technical solution of the utility model, the buffer layer specifically comprises a plurality of buffer support pads distributed along the length direction of the drainage pipe, and the plurality of buffer support pads are radially distributed with the axis of the drainage pipe as the center.

[0013] As a preferred technical solution of the present utility model, the buffer support pad is made of fluororubber.

[0014] As a preferred technical solution of the present utility model, the replaceable inner tube is made entirely of PVC material.

[0015] The beneficial effects of the utility model are embodied in:

[0016] Optimized sound and thermal insulation performance: The porous thermal and sound insulation layer effectively reduces the influence of external temperature and the transmission of noise, improving the operating environment of the pipeline and the quality of life of surrounding residents. This design is particularly suitable for urban areas, where drainage pipes are often located in densely populated areas.

[0017] Innovative buffer protection design: The introduction of the buffer layer, especially the buffer support pads made of fluororubber, provides additional protection for the drainage system. These pads can evenly disperse the impact force of the fluid and the external pressure, prevent local damage caused by impact and pressure, and further extend the service life of the pipeline.

[0018] Convenient maintenance and replacement system: The positioning system in the design, including the positioning guide groove of the inner fixed tube and the positioning convex strip of the replaceable inner tube, simplifies the installation and maintenance process of the pipeline. This precise positioning design ensures that the replaceable inner tube can be installed or replaced quickly and accurately, greatly reducing maintenance time and cost.

[0019] Environmental protection and cost-effectiveness: By adopting a replaceable inner tube made of PVC, it not only provides good corrosion resistance and easy processing, but also supports the concept of environmental protection. The use of PVC pipes reduces the diversity of materials required for maintenance, and PVC materials can be recycled, reducing the burden on the environment.

[0020] In summary, the implementation of this municipal drainage pipeline design not only improves the performance of the pipeline system, but also reflects the consideration of environmental protection, while achieving the dual optimization of economic cost and maintenance convenience. This design can serve as a model for urban infrastructure construction and maintenance, suitable for new construction or renovation projects, and provides an efficient, reliable and economical solution for urban drainage systems.

[0032] The utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] It should be noted that if the utility model embodiments involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it.

[0035] Please refer to the instruction manual Figure 1-Figure 5 The utility model provides a design of a municipal drainage pipeline, which aims to improve the service life and performance of the drainage pipeline while reducing maintenance costs. The following is a specific implementation of the municipal drainage pipeline:

[0036] Structural setting: The drainage pipe is composed of an external fixed pipe 1, and its external structure is sturdy and durable, and can withstand the influence of ground pressure and external environment. A thermal insulation and sound insulation layer 2 is provided on the inner side of the external fixed pipe 1. This layer adopts a porous structure, which can effectively block external temperature changes and noise transmission, and improve the overall thermal insulation and noise reduction performance of the pipe. A buffer layer 3 is provided on the inner side of the thermal insulation and sound insulation layer 2. This layer can absorb and disperse the impact force of the fluid passing through the pipe, as well as external impact, reduce direct impact on the internal fixed pipe 4, and thus extend the service life of the pipe. The internal fixed pipe 4 further protects the replaceable inner pipe 5. A replaceable inner pipe 5 is provided on the inner side of the internal fixed pipe 4. The replaceable inner pipe 5 is convenient for quick replacement when the pipe is damaged or aged, thereby reducing maintenance costs.

[0037] Material selection: The external fixed pipe 1 and the internal fixed pipe 4 are both cast with concrete. This material has high strength and durability, can effectively resist corrosion and mechanical damage from the external environment, and ensure long-term stable operation of the pipeline. The thermal insulation layer 2 is filled with porous thermal insulation and sound insulation board material. This material has excellent heat insulation and sound absorption properties, can effectively reduce the temperature difference and noise transmission inside and outside the pipeline, and improve the comfort of pipeline use. The buffer layer 3 is composed of a number of buffer support pads 31 distributed along the length of the drainage pipe. These pads are radially distributed with the axis of the drainage pipe as the center, which can evenly disperse the impact force of the fluid, prevent local stress concentration, and extend the service life of the pipeline. The buffer support pad 31 is made of fluororubber material, which has good elasticity and weather resistance, and can maintain stable buffering performance under various environmental conditions. The replaceable inner pipe 5 is made of PVC material as a whole. This material has good corrosion resistance and easy processing characteristics, which is convenient for daily maintenance and replacement operations.

[0038] Positioning system: The inner wall of the inner fixed pipe 4 is evenly provided with a number of positioning guide grooves 41 distributed along the entire length of the drainage pipe. These guide grooves play a guiding and fixing role during the pipe installation process, ensuring that the replaceable inner pipe 5 can be accurately installed in the inner fixed pipe 4 without deviation or loosening. The outer wall of the replaceable inner pipe 5 is evenly provided with a number of positioning convex strips 51 distributed along the entire length of the drainage pipe. These convex strips correspond to the positioning guide grooves 41 and are fixed in the guide grooves by snap-fitting during installation to form a firm connection structure. This design not only simplifies the installation process, but also facilitates future maintenance and replacement work, reducing maintenance time and cost.
