Description

Technical Field

[0001] The utility model belongs to the technical field of pipe gallery construction engineering application, and specifically relates to a comprehensive pipe gallery anti-seismic device applied in a soft soil environment. Background Art

[0002] The utility corridor is a public facility built underground in the city for laying municipal utility pipelines, which is implemented with unified planning, design, construction and maintenance. It plays an important role in the city's power transmission, gas transmission, sewage, rainwater treatment, communications, water supply, heat, etc.

[0003] The utility corridor has the advantages of large capacity, convenient maintenance, and centralized management. For example, the construction of underground utility corridors can avoid such repetitive excavation, bring various pipelines together, reduce ground engineering, and improve the efficiency of urban road use. Although certain costs will be added during the construction process, in the long run, it can reduce the cost of urban operation and maintenance and improve the overall benefits of the city. In addition, the construction of underground utility corridors can also improve the efficiency and convenience of urban management. Underground utility corridors can centrally manage various pipelines, facilitate maintenance and repair, and reduce the difficulty and cost of pipeline maintenance. At the same time, underground utility corridors can better protect pipelines, prevent them from being destroyed and damaged by third parties, and improve the safety of the city. By building underground utility corridors, more space can be left for the future development of cities, which is convenient for urban renewal and transformation.

[0004] Soft base soil generally refers to soft soil, clay, silt and organic soil in the foundation. The water content of soft base soil is greater than or close to the flow limit, and the natural porosity is greater than 1, which means that the compressibility is very high and the strength is very low. Because the foundation contains soft base soil, it often has low bearing capacity, large settlement, and a long time for settlement, so reinforcement is often required.

[0005] After searching: ① Application No. / Patent No. 202010661961.2 discloses an anti-seismic energy-absorbing bearing for an urban integrated pipe gallery, which belongs to the technical field of anti-seismic structural devices for underground integrated pipe galleries, and is characterized in that: it includes a bearing body, the upper part of the bearing body has a supporting surface for supporting the pipe body, the bearing body is provided with a rigid pulling member for fixing the bearing body, a flexible pulling member is embedded inside the bearing body, the upper end of the flexible pulling member is used to connect with the pipe body and is arranged on the supporting surface, the flexible pulling member includes a sleeve embedded in the bearing body and a tension spring arranged in the sleeve, and the upper end of the tension spring is connected to the pipe body. This bearing can reduce the impact of earthquakes on the pipe body and improve the anti-seismic capacity of the pipes in the underground integrated pipe gallery.

[0006] ② Application No. / Patent No. 202222921045.5 discloses an anti-seismic support for an integrated pipe gallery, including a support body, an anti-seismic component and a connecting component, wherein the anti-seismic component includes an upper support frame and a lower support frame symmetrically installed at the upper and lower ends of the center of the support body. The anti-seismic support for an integrated pipe gallery described in the utility model, the first shock-absorbing sleeve and the first shock-absorbing spring at the upper and lower ends of the upper support frame and the lower support frame, and the second shock-absorbing sleeve and the second shock-absorbing spring shock-absorbing pad on both sides can be used for the pipes placed between the upper support frame and the lower support frame, and play a shock-absorbing effect in the horizontal and vertical directions. The symmetrical structure of the first shock-absorbing sleeve and the second shock-absorbing sleeve also makes the anti-seismic component inside the support body have strong stability and balance, and thus has a strong anti-seismic effect. The connecting grooves opened on the four sides of the support body and the connecting splints installed between the connecting grooves are also convenient for fixing and connecting multiple groups of support bodies, thereby improving their connection effect and reducing the overall occupied space of the support body.
