Title:
UNDERGROUND UTILITY TUNNEL BEARING DAMPING CAPACITY ENHANCED ANTI-SEISMIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/098074
Kind Code:
A1
Abstract:
Disclosed in the present invention is an underground utility tunnel bearing damping capacity enhanced anti-seismic system, comprising pipeline fixing assemblies mounted on the inner walls of the left and right sides of an underground space. Each pipeline fixing assembly comprises a plurality of lifting/lowering frames and lifting/lowering mechanisms which are vertically arranged from top to bottom. A telescopic end of the lifting/lowering mechanism is fixedly connected to the lifting/lowering frame on the lowermost side. One side of the lifting/lowering frame is slidably connected to the inner wall of the underground space. The lifting/lowering frame is provided with a groove for allowing a pipeline to be placed. A pipeline fixator used for fixing the pipeline is mounted inside the groove. According to the present invention, when the pipelines, the pipeline fixators and the lifting/lowering frames are vibrated, the lifting/lowering frames slide on the inner wall of the underground space, two adjacent pipeline fixators move relatively, and a telescopic spring absorbs vibration, so that hard contact between the pipeline and the vibration is avoided, damping protection is conducted on the pipeline, and the anti-seismic capacity of the underground tunnel is improved.
