Construction method for shaft type underground garage
The invention relates to a construction method for a shaft type underground garage. The construction method comprises the following steps that firstly, uplift piles are driven around a drop shaft or a caisson; secondly, grouting is carried out after pile forming, the uplift piles are strengthened, and pile heads are expanded; thirdly, bolt holes are drilled in the pile sides of the uplift piles, and guide rails are embedded; fourthly, steel corbels are installed on the embedded guide rails and used for installing a weight balance system of a vehicle garage entering and exiting loading device; fifthly, a reinforced concrete shaft is poured on the ground; sixthly, a sinking bottom joint drop shaft or a bottom joint caisson is evenly dug till sinking is finished; seventhly, the caisson or the drop shaft is ejected; eighthly, a second joint drop shaft or a second joint caisson is built, the sinking drop shaft or the caisson continues to be dug, and a next joint shaft wall is built continuously; ninthly, after the designed elevation is achieved during sinking, foundation cleaning is carried out, and bottom sealing processing is carried out on the drop shaft or the caisson; and tenthly, designing and top sealing are carried out in a construction well. Compared with the prior art, the construction method has the beneficial effects that reliability is achieved, the construction period is short, and the shaft type underground garage digging construction is economical and reasonable.
