technical field

The invention belongs to the technical field of urban underground engineering construction, and particularly relates to a method for constructing an underground automatic garage structure.

Background technique

With the rapid development of the automobile industry and the acceleration of urbanization in my country, many cities in China have encountered the problem of parking difficulties. The way to save land resources is to build underground garages. Among them, the underground automatic garage is more and more widely used because of its unmanned operation, high degree of automation, and small footprint. The underground automatic garage generally includes a lift channel, a translation channel for the car carrier, and two parking space channels formed by the parking spaces on both sides of the translation channel. At present, the method of constructing underground garages and parking lots is to construct several adjacent tunnels by using a rectangular pipe jacking machine to jack into the rectangular jacking pipe according to the design of the parking lot and the garage. The rectangular jacking pipe adopts a mixed structure of precast concrete and section steel; , After the branch jacking construction is completed, the section steel between the two adjacent rectangular jacking pipes on the left and right is removed, and reinforced concrete columns, beams, and bottom plates are installed to complete the construction of the underground parking garage.

This method needs to jack into several tunnels first, then construct columns and beams, and then remove the section steel between the left and right adjacent rectangular jacking pipes, which is a relatively cumbersome process.
