Four-layer stair-like city underground comprehensive body

Abstract

The invention provides a four-layer stair-like city underground comprehensive body. The four-layer stair-like city underground comprehensive body mainly comprises an all-purpose road special cabin, a minibus special cabin, a lower layer traffic urgent evacuation cabin, an upper layer traffic urgent evacuation cabin, a sponge city cabin, an electric power cabin, a telecommunication cabin, a gas cabin, a nonelectric utility tunnel cabin, a pedestrian cabin and an underground parking. The four-layer stair-like city underground comprehensive body has the beneficial effects that the first and second layers at the bottom of the comprehensive body are arranged in a stair shape, the structure is stressed more stable, soil pressure, concentrated stress and the like can reach a better state through the stair shape relative to a rectangle and the like, the stair shape provides symmetric reliable fulcrums for the whole structure, and internal force of an inner layer structure is remarkably reduced; due to the stair-shaped structure, industrial dismounting is quite convenient, production is facilitated, mounting is easy, and the industrialization process is prompted advantageously; and the bottom layer is fully used, the comprehensive body is safer, contributions are made to construction of sponge cities, and sewage drainage and collection are optimized.

Description

Technical field [0001] The invention belongs to the technical field of urban underground road engineering and municipal facilities, and particularly relates to a four-story ladder-shaped urban underground complex. Background technique [0002] At present, the construction of urban traffic is in full swing. As the country further advances the strategy of integrated pipe corridors and sponge cities, my country’s large and medium-sized cities will surely set off a new round of underground engineering construction. Due to the scarcity of underground space, there will , Urban underground complexes such as urban underground express highways and urban underground construction spaces are in huge demand. [0003] Japan and Europe and the United States are in a leading position in the development and construction of underground space. They were the first to advocate and put forward the concept of integrated and three-dimensional development of underground cities and urban underground spaces. ...
