Underground parking garage construction method

Abstract

The invention discloses an underground parking garage construction method, and belongs to the technical field of underground space construction. The underground parking garage construction method comprises the following steps that a steel jacket box enclosure structure is hammered to the underground through a resonance-free hammer, a structural top plate is mounted at the top of the steel jacket box enclosure structure, a soil layer with a set height is excavated from top to bottom in the steel jacket box enclosure structure, structural plates are mounted in the excavated soil layer at the lowermost end, and the two steps of excavating the soil layer with the set height from top to bottom in the steel jacket box enclosure structure and mounting the structural plates in the excavated soil layer at the lowermost end are repeated till the number of the structural plates reaches the design required number. The resonance-free hammer is used for hammering the steel jacket box enclosure structure to the underground, no mud is generated, the construction speed is high, the steel jacket box enclosure structure, the structural top plate and the structural plates are all prefabricated parts, the construction efficiency is improved, the whole structure is not provided with a lining wall, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of underground space construction, in particular to an underground parking garage construction method. Background technique [0002] With the rapid growth of the urban economy, the demand for urban space utilization has increased, and the construction of urban underground space has gradually increased, such as the demand for underground parking garages. [0003] At present, the common underground parking garage is the caisson type underground parking garage. The construction of this garage mostly adopts the vertical excavation technology of Herrenknecht VSM (Sunken Shaft Heading Machine). This construction method has high construction efficiency and can be prefabricated. However, if this kind of garage is added in old residential areas, urban public areas, and office areas with a certain history, the construction method is limited, and the construction method has a large amount of mud treatment, long assembl...
