Construction method of stereo garage foundation open caisson

Abstract

A construction method of a stereo garage foundation open caisson comprises the following steps that S1, an underground wall body is vertically divided into a plurality of layers in the height direction, and the thickness of the upper-layer underground wall body is smaller than that of the lower-layer underground wall body; S2, the position of an open caisson is determined; S3, a drainage ditch isarranged; S4, a blade foot layer is installed, specifically, first sand grains are packed between a blade foot steel foundation unit and a soil layer along with the sinking process of the blade foot layer; S5, a module layer is installed, specifically, second sand grains are packed between a module steel foundation unit and the soil layer along with sinking of the module layer; S6, the module steel foundation unit is continuously hoisted, and the space between the module steel foundation unit and the soil layer is filled with second sand grains along with sinking of the module layer; S7, the step S6 is repeated to install other module layers until a shaft sinks to a preset depth layer by layer; and S8, bottom sealing of the open caisson is carried out. The technical problems that an underground stereo garage is long in construction period, difficult to construct, low in structural strength and high in manufacturing cost are solved, and the construction method is widely applied to stereo garage construction.

Description

technical field [0001] The invention relates to the technical field of construction of a three-dimensional garage, in particular to a construction method for a foundation caisson of a three-dimensional garage. Background technique [0002] With the continuous improvement of people's living standards, more and more people have purchased private cars; it has a significant impact on urban traffic and the environment. The emergence of difficult parking problems has also brought huge business opportunities and a broad market to the mechanical parking equipment industry. When business opportunities and competition coexist, my country's mechanical parking equipment industry will also enter a stable development stage from a stage of rapid development. The future market is huge, but the demand for products will develop towards two extremes: one extreme is the extreme price, the market needs a lot of low-priced mechanical parking equipment, as long as it can achieve the purpose of in...
