Description
Technical Field
[0001] The utility model relates to the technical field of underground pipe corridors, in particular to a multi-stage anti-seismic and shock-absorbing structure of an underground pipe corridor. Background Art
[0002] An underground utility gallery is an underground urban pipeline corridor, which is a tunnel space built underground in the city, in which various engineering pipelines such as electricity, communications, gas, heating, water supply and drainage are set up. It has special inspection ports, lifting ports and monitoring systems, and implements unified planning, design, construction and management. It is an important infrastructure and "lifeline" to ensure the operation of the city.
[0003] In the existing technology, most of the current underground pipe corridors adopt shallow underground structures. Due to the small burial depth, the top is very easy to be damaged by vehicle loads, explosion loads, mechanical loads, etc. In addition, when an earthquake occurs, the pipe corridor will move with the surrounding soil in the longitudinal and transverse waves of the earthquake. Due to the different deformation capacities of different soil layers, the pipe corridor will be unevenly stressed and will bend, deform, crack, or even collapse. When these problems occur, the pipes installed in the pipe corridor will suffer varying degrees of damage, resulting in the loss of power for urban operation. For this reason, we propose a multi-level seismic and shock-absorbing structure for underground pipe corridors to solve the above problems. Summary of the invention
