Mechanical underground excavation construction method for large underground parking lot

Abstract

The invention discloses a mechanical underground excavation construction method for a large underground parking lot, comprising the following steps: constructing two parallel construction tunnels at two ends of the position of the proposed space of the parking lot according to the design condition of the parking lot, marking the rectangular section of the space of the parking lot on the side wall of the construction tunnel, and dividing the rectangular section of the whole space of the parking lot into a plurality of small rectangular sections with same size; and then carrying out segmental jacking construction sequentially on the small rectangular sections, namely the linear distance between the two construction tunnels, by adopting a rectangular tube push bench, and synchronously arranging the rectangular tube push bench inside, then removing profile steel parts between two adjacent rectangular pipe jacking rooms, and constructing reinforced concrete stand columns, beams and bottom plates, thus completing construction of the underground parking lot. The method can be used for solving the difficulty of constructing an underground parking lot without disturbing the ground environment conditions of urban areas; is high in construction speed, small in environmental influence and high in economic benefits; and is high in mechanization degree and small in construction risks.

Description

technical field [0001] The invention belongs to the technical field of urban underground engineering construction, and relates to a mechanical underground excavation construction method for a large underground parking lot. Background technique [0002] With the popularization of automobiles in people's lives, the number of motor vehicles has increased, and the problem of difficult parking of motor vehicles has begun to appear. In many cities, large public places such as administrative units, business offices, restaurants, hotels, restaurants and entertainment venues, airport stations, cinemas, hospitals, scenic spots, parks, commercial shopping centers, large wholesale markets, farmers' markets, etc. have no parking lots. Either there are always not enough parking spaces, and it is even more difficult to find a parking space. "Difficulty in parking" followed by "difficulty in driving" has become another universal problem that plagues the development of road traffic in many ...
