Description

TECHNICAL FIELD

[0001] The utility model relates to municipal engineering pipeline connection field, concretely relates to a municipal engineering pipeline sleeve type anti deformation joint structure. BACKGROUND

[0002] In municipal engineering, pipeline system is an important infrastructure to ensure the normal operation of the city. With the continuous development of urban construction, higher requirements are put forward for the safety, stability and durability of the pipeline system.

[0003] At present, the traditional cement pipeline butt joint mode has many problems. On the one hand, the gap at the pipeline butt joint place is easy to cause medium leakage. Once leakage occurs, not only resource waste will be caused, but also environmental pollution and serious safety hidden danger may be caused. On the other hand, external environmental factors have great influence on the pipeline butt joint place. For example, water can easily penetrate through the interface, which can also shorten the service life of the pipeline. Especially for buried pipeline, the problem of water erosion in soil is more prominent. Moreover, when the pipeline produces slight displacement or vibration due to temperature change, ground subsidence or other external force, the traditional butt joint mode is difficult to effectively buffer and absorb shock, which leads to stress concentration at the interface, easy to damage, reduces the stability and reliability of the pipeline system.

[0004] In summary, the existing municipal engineering pipeline butt joint structure has many problems in sealing, waterproofing, buffering, protection and construction, and a new type of municipal engineering pipeline sleeve type anti deformation joint structure is urgently needed to solve these problems. UTILITY MODEL CONTENT

[0005] Therefore, in order to solve the above problems, the utility model provides a municipal engineering pipeline sleeve type anti deformation joint structure.

[0006] The utility model is realized by constructing a municipal engineering pipeline sleeve type anti deformation joint structure, which comprises a pipeline A and a pipeline B, characterized by that: a buffer moisture-proof layer is filled in the butt joint gap of the pipeline A and the pipeline B; the outside of the butt joint gap of the pipeline A and the pipeline B is wrapped by a C25 reinforced concrete sleeve; the concrete sleeve can serve as a solid protective layer, and the C25 reinforced concrete has high compressive strength and certain bending resistance. The wrapping at the pipeline butt joint place can provide additional support for the pipeline, especially in the case of pipeline crossing road, railway or bearing large external load, which can effectively disperse the pressure and prevent the pipeline from deforming and cracking due to external force, so as to protect the safe operation of the pipeline. The close combination between the reinforced concrete sleeve and the pipeline can make the stress of the pipeline more uniform during operation. Especially for long distance pipeline, the stress concentration caused by factors such as pipeline self weight and temperature change can be reduced, and the risk of pipeline cracking or leakage can be reduced.

[0009] The utility model discloses a municipal works pipeline casing formula anti -deformation joint structure, its characterized in that;C25 reinforced concrete casing's smearing angle department fills through M10 mortar.

[0010] The utility model discloses a municipal works pipeline casing formula anti -deformation joint structure, its characterized in that;C25 reinforced concrete casing's smearing angle department fills through M10 mortar.

[0011] This utility model has the following advantages: In the municipal engineering pipeline sleeve-type anti-deformation joint structure described in this utility model, the joint between pipe A and pipe B is filled with a buffer moisture-proof layer; the outside of the joint between pipe A and pipe B is wrapped with a C25 reinforced concrete sleeve. On the one hand, the concrete sleeve can serve as a robust protective layer, and C25 reinforced concrete has high compressive strength and a certain bending resistance. Wrapping it around the pipe joint can provide additional support for the pipeline, especially when the pipeline crosses roads or railways or bears large external loads, effectively dispersing pressure and preventing the pipeline from deforming or cracking due to external forces, thus protecting the safe operation of the pipeline. The tight connection between the reinforced concrete sleeve and the pipeline can make the stress on the pipeline more uniform during operation. Especially for long-distance transmission pipelines, it can reduce stress concentration caused by factors such as pipeline weight and temperature changes, reducing the risk of pipeline cracking or leakage. On the other hand, the buffer moisture-proof layer described in this application uses asphalt-impregnated hemp fiber. Asphalt-impregnated hemp fiber has good flexibility and plasticity, capable of filling gaps at pipe joints, preventing liquid or gas leakage from the interface, and acting as a sealant for the pipeline system. This ensures the safe transport of the medium within the pipeline under pressure, preventing leakage that could lead to resource waste, environmental pollution, and safety hazards. The hemp fiber also has a certain degree of elasticity. When the pipeline experiences minor displacement or vibration due to temperature changes, ground subsidence, or other external forces, the asphalt-impregnated hemp fiber can act as a buffer, reducing stress concentration at the interface, lowering the risk of pipeline interface damage, and improving the stability and reliability of the pipeline system. Asphalt has a certain degree of corrosion resistance, protecting the hemp fiber and pipe interfaces from the erosion of some chemicals. For pipelines transporting corrosive media or those in corrosive soil environments, asphalt-impregnated hemp fiber provides additional protection, enhancing the corrosion resistance of the pipe interfaces and ensuring the integrity of the pipeline system.

[0016] Sealing effect: hemp wadding soaked in asphalt has good flexibility and plasticity, can fill the gap at pipeline butt joint, prevent liquid or gas from leaking at the interface, play the role of sealing pipeline system, ensure that the medium (such as water, oil, gas, etc.) in the pipeline can be safely transported under pressure, prevent leakage from causing resource waste, environmental pollution and safety hazards.

[0017] Waterproof and moisture-proof: asphalt itself has hydrophobicity, can effectively block water penetration, and the waterproof performance of hemp wadding soaked in asphalt is greatly enhanced.This can prevent external moisture from entering the pipeline interface, avoid the pipeline from rusting and corroding due to long-term contact with moisture, thereby prolonging the service life of the pipeline.For buried pipeline, it can effectively resist the erosion of water in soil to the pipeline interface.

[0018] Buffering and shock absorption: hemp wadding has a certain elasticity, when the pipeline produces slight displacement or vibration due to temperature change, ground subsidence or other external forces, hemp wadding soaked in asphalt can play a buffering role, reduce stress concentration at the interface, reduce the risk of pipeline interface damage, improve the stability and reliability of the pipeline system.

[0019] Corrosion resistance: asphalt has certain corrosion resistance, which can protect hemp wadding and pipeline interface from being eroded by some chemicals.For pipelines transporting corrosive media, or pipelines in corrosive soil environment, hemp wadding soaked in asphalt can provide additional protection, enhance the corrosion resistance of pipeline interface, and ensure the integrity of pipeline system.

[0020] Construction is convenient: hemp wadding material is widely available, relatively low in price, easy to operate after soaking in asphalt, can be cut and filled according to the size and shape of pipeline interface, construction technology is simple, does not need special equipment and technology, can improve construction efficiency and reduce construction cost.

[0021] The outer surface of the joint of pipeline A1 and pipeline B2 is coated with a 20cm thick clay protective layer 6, forming a waterproof layer around the pipe body.

[0022] Wrapping C25 reinforced concrete sleeves 4 at pipe joints has the following effects and benefits:

[0023] Enhanced structural strength: C25 reinforced concrete has high compressive strength and certain bending resistance. Wrapping at pipe joints can provide additional support for the pipeline, especially when the pipeline crosses roads, railways, or bears larger external loads, effectively dispersing pressure and preventing pipeline deformation and rupture due to external forces, protecting the safe operation of the pipeline.

[0024] Protecting the pipeline: The concrete sleeve can serve as a strong protective layer, isolating the pipeline from the external environment. It can prevent mechanical damage to the pipeline, such as being scratched by excavation equipment or being hit by other objects; it can also resist the erosion of harmful substances in the soil on the pipeline, extending the service life of the pipeline.

[0025] Waterproof sealing: High-quality C25 reinforced concrete has good waterproof performance, effectively preventing groundwater or other water sources from seeping into the pipe joint. In areas with high groundwater levels or when the pipeline transports easily leachable media, this waterproof sealing effect is particularly important, as it can prevent the surrounding soil from softening due to water infiltration, affecting the stability of the pipeline.

[0026] Improving the stress state of the pipeline: The close combination between the reinforced concrete sleeve and the pipeline can make the stress of the pipeline more uniform during operation. Especially for long-distance transportation pipelines, it can reduce stress concentration caused by factors such as pipeline self-weight and temperature changes, reducing the risk of pipeline cracking or leakage.
