Steel sheet pile and open caisson combined underground garage and construction method thereof

Abstract

The invention discloses a steel sheet pile and open caisson combined underground garage. A body structure of the underground garage comprises an external wall and an external wall supporting structure; the external wall is composed of an upper external wall body and a lower external wall body which are connected in an up-down manner; the upper external wall body is a steel plate pile wall formed by connecting steel plate piles with one another; the lower external wall body is a reinforced concrete well wall of an open caisson; and the external wall supporting structure serves as a supporting structure of a parking platform of the underground garage at the same time. The external wall of the underground garage adopts a compounded external wall composed of the steel plate pile wall and the well wall of the open caisson, and the beneficial effects of the steel plate pile wall and the well wall of the open caisson are combined. The invention further discloses a construction method of the underground garage. According to the construction method, firstly, the steel plate piles sink to form the steel plate pile wall; and then the open caisson is poured in the steel plate pile wall and sinks. By means of the construction method, the building cost of the underground garage is successfully reduced, and the building time of the underground garage is successfully shortened.

Description

technical field [0001] The invention belongs to the field of underground structure construction, and in particular relates to a combined underground parking garage of steel sheet piles and caissons and a construction method thereof. Background technique [0002] With the development of the economy, urban land is increasingly in short supply. Intensive and economical use of land, scientific and rational development and utilization of urban underground space, and development of new living and development space have become an inevitable choice. Many domestic cities have gradually emerged to develop and utilize underground space. upsurge. The development and utilization of underground space can alleviate traffic congestion, reduce urban air pollution, improve the urban ecological environment, and facilitate the lives of urban people. The problems of traffic difficulties, road difficulties and parking difficulties in large and medium-sized cities are common and increasingly seri...

AI Technical Summary

Problems solved by technology

Since the steel sheet pile is close to the caisson wall, it is extremely difficult for the manipulator to operate the piling. As the caisson sinks, the inner plane of the well that needs to be piled will inevitably become deeper and deeper, and the piling equipment will not be able to perform piling operations on the ground
