Description

Technical Field

[0001] The utility model relates to the technical field of tunnel walls, in particular to an anti-settling rubber hose structure. Background Art

[0002] Urban underground pipelines refer to pipelines and their ancillary facilities for water supply, drainage, gas, heat, electricity, communications, radio and television, industry, etc. within the city. They are important infrastructure and "lifelines" to ensure the operation of the city. Urban underground pipelines include thermal pipelines, fire water supply pipelines, sewage pipes, ventilation pipes, etc. These pipelines form a huge underground pipeline system. In the construction of urban underground pipelines, special attention should be paid to the problems of pipeline rupture and sinking. At present, urban underground pipelines are mainly composed of cast iron pipes, steel pipes, plastic pipes and other materials. When the ambient temperature is too low, these materials will become cold and brittle, causing the pipeline to rupture. When the temperature is too high, the steel pipe will undergo crystal creep, causing the pipeline to rupture, and the plastic pipe will deform and leak. In specific scenarios, for example, when vehicles pass through the road surface, they will generate vibration impact loads on the road surface and the pipelines below. In particular, the vibration impact loads of heavy vehicles and overloaded vehicles will seriously affect the safety of underground pipelines. Vehicles transfer their weight to the road surface through contact with the road surface, and the vibration impact is then transferred from the road surface to the underground pipeline, causing the steel pipeline ring weld to fail and rupture. According to expert analysis, the increase in vehicle overload weight will cause geometric damage to the road surface. A truck that exceeds the limit by 10% will increase the damage to the road by 40%. In addition, the vibration impact of seismic waves on underground pipelines is also very serious. If an earthquake occurs, the seismic wave will propagate vibration from the source to the surrounding areas. The transverse wave is a shear wave. Its shaking fluctuations will cause the pipeline stress concentration to be unable to be eliminated, thereby causing the pipeline to deform and bend severely, leading to pipeline rupture.

[0003] However, some hose structures have poor elasticity, are easily damaged, have poor weather resistance, ozone resistance and electrical insulation, and have a poor service life.

[0004] Therefore, those skilled in the art are in urgent need of designing an anti-settling rubber hose structure. Utility Model Content
