Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, specifically to a pipe damping joint. Background Technology

[0002] In municipal construction and water conservancy projects, drainage pipes serve as the lifeblood of a city, bearing the crucial responsibility of transporting rainwater and sewage. However, under adverse geological conditions, such as quicksand, soft soil, and silty soil, the installation and operation of drainage pipes face numerous challenges. In such cases, the application of damping effects can provide an effective solution to these problems.

[0003] In short, damping effect refers to the phenomenon that an object consumes energy due to internal friction or external resistance during vibration or motion. In drainage pipe systems, damping effect is mainly reflected in the absorption and mitigation of external forces such as water flow impact, soil pressure, and dynamic load changes by the pipe material.

[0004] In unfavorable geological formations, the solid phase of the pipeline medium is unstable, the soil bearing capacity is low and the deformation is large. Traditional drainage pipelines are prone to settlement and damage due to unstable foundations. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe damping joint to solve the technical problem that drainage pipes are prone to settlement and damage due to unstable foundation.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A pipe damping pipe section includes a pipe section body, a reinforcing sleeve is fitted around the outer periphery of the pipe section body, and joint sleeves are fixedly fitted at both ends of the pipe section body. The outer periphery of the joint sleeve is flush with the outer periphery of the reinforcing sleeve, and the inner periphery of the joint sleeve is flush with the inner periphery of the pipe section body. A pipe joint for pipe connection is fixedly installed on the side of the joint sleeve away from the pipe section body.

[0008] The main body of the pipe section is formed by processing pipe material, the pipe material is pipe filler, and several wave springs are embedded in the pipe filler.

[0009] Preferably, the reinforcing sleeve is fitted with a construction sleeve on its outer periphery, and the construction sleeve is made of a biodegradable material.

[0010] Preferably, the construction sleeve is adhered to the outside of the reinforcing sleeve using cooked starch composite adhesive.

[0011] Preferably, the wave spring is a wave-shaped twisted steel bar spring.

[0012] Preferably, the minimum distance between adjacent wave springs is not less than 20 mm.

[0013] Preferably, the surface distance between the wave spring and the tubular packing is not less than 5 mm.

[0014] Preferably, the outer periphery of the pipe joint is fitted with multiple sealing rings.

[0015] Preferably, a sealing retaining ring for fixing the sealing ring is fixedly provided on the outer periphery of the pipe joint.

[0016] The beneficial effects of this utility model are:

[0017] (1) By applying damping theory to drainage pipes, the pipes can effectively absorb the stress generated by ground deformation through their elasticity, toughness, and special structure, thus compensating for the pipe's elongation under dynamic loads. At the same time, it can also block and suppress the amplification of dynamic carrier waves, reducing the risk of pipe damage. In addition, damping design can also reduce the impact of water flow on the pipes, reduce the internal pressure of the pipes, and extend their service life.

[0018] (2) Damping design can effectively absorb the vibration and dynamic load generated by water flow impact and other external forces to catalyze the movement of the pipeline and generate resonance, thereby improving the overall stability of the pipeline system and the safety of urban roads.

[0019] (3) By adjusting the damping characteristics of the pipeline structure, it can better adapt to the deformation of poor strata, reduce pipeline damage caused by unstable foundation, and effectively reduce the superposition of tiered forces. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention / utility model, and not all embodiments. Based on the embodiments of the present invention / utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention / utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0026] In the description of this invention / utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-2 As shown, this utility model is a pipe damping pipe section, including a pipe section body 1, a reinforcing sleeve 2 sleeved on the outer periphery of the pipe section body 1, and joint sleeves 3 fixedly sleeved at both ends of the pipe section body 1. The outer periphery of the joint sleeve 3 is flush with the outer periphery of the reinforcing sleeve 2, and the inner periphery of the joint sleeve 3 is flush with the inner periphery of the pipe section body 1. A pipe joint 4 for pipe connection is fixedly installed on the side of the joint sleeve 3 away from the pipe section body 1.

[0028] The main body 1 of the pipe section is formed by processing pipe material, the pipe material is pipe material filler 11, and a number of wave springs 12 are embedded in the pipe material filler 11.

[0029] Specifically, the use of LDPE material for the pipe filler 11 allows the pipe section to have sufficient flexibility, enabling both the flexible pipe body and the water in the pipe to have self-damping properties. This allows the pipe section to compensate for the length of the pipe under dynamic load tension, resolving the contradiction between tight connection and damping.

[0030] Furthermore, the size of the wave spring 12 is configured according to the size of the main pipe, and the stiffness of the damping pipe section ring is 1.5 times that of the matching pipe material.

[0031] The skeleton structure of the wave spring 12 ensures that the tube section has sufficient ring stiffness, and allows for elastic deformation and recovery at any angle of 360 degrees to prevent further formation of tiered forces and resonance damage.

[0032] The material coating of the pipe filler 11 allows the pipe section to have sufficient flexibility.

[0033] It should be noted that pipe fittings 4 are made at both ends of the pipe section to connect with conventional pipes. The fittings can be flanges, clamps, or lock-type sockets. This allows for smooth connection with other pipe sections to form a complete piping system.

[0034] In an optional embodiment, a construction sleeve 7 is fitted around the outer periphery of the reinforcing sleeve 2. The construction sleeve 7 is made of a biodegradable material and is attached to the outside of the reinforcing sleeve 2 with cooked starch composite adhesive.

[0035] It should be noted that when the pipe section is used in pipe jacking operations, a temporary load-bearing layer, construction sleeve 7, is specially fabricated on the outside of the pipe. This construction sleeve 7 is composed of bamboo strips and connected by biodegradable cooked starch composite adhesive. This design not only provides necessary support and protection during construction, but also, because the outermost bamboo strips are exposed, allows for rapid degradation after pipe jacking is completed, reducing environmental impact, while simultaneously ensuring the pipe section's design functionality takes effect quickly.

[0036] In an optional embodiment, the wave spring 12 is a wave-shaped torsion bar spring.

[0037] It should be noted that the twist is to ensure a better bond between the filling material and the wave spring.

[0038] In an optional embodiment, the minimum spacing between adjacent wave springs 12 is not less than 20 mm.

[0039] It should be noted that, in order to ensure the effective elasticity of the compensation pipe section and the damping characteristics of the wave spring, the spacing between the wave springs 12 shall not be less than 20mm.

[0040] In an optional embodiment, the surface distance between the wave spring 12 and the tubular packing 11 is not less than 5 mm.

[0041] In an optional embodiment, the outer periphery of the pipe fitting 4 is fitted with multiple sealing rings 6.

[0042] It should be noted that the sealing ring 6 improves the sealing performance of the pipe joint 4.

[0043] In an optional embodiment, a sealing retaining ring 5 for fixing the sealing ring 6 is fixedly provided on the outer periphery of the pipe joint 4.

[0044] It should be noted that the sealing ring 5 is designed to ensure the stability of the sealing ring 6 during installation.

[0045] The working principle of this invention is as follows: During construction, one such pipe section is installed every 20 meters. When the pipeline is subjected to dynamic loads, such as earthquakes, this specially designed pipe section can effectively absorb and disperse the stress generated by the dynamic load, preventing stress concentration from damaging the pipeline. This makes the entire pipeline system more stable and reliable, especially suitable for use in earthquake-prone cities, improving the safety and durability of the pipeline under special geological conditions.

[0046] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
