Construction method for shaft type underground garage

Abstract

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.

Description

technical field [0001] The invention relates to an excavation method for an underground parking garage, in particular to an excavation construction method for a shaft type underground parking garage. Background technique [0002] With the development of cities in our country and the improvement of people's living standards, people generally like to commute and travel by car. However, for the apartment complexes built in the last century, many communities did not build underground parking garages and enough parking garages due to short-sighted planning. ground parking spaces. Now, it is an urgent need to solve the difficult problem of parking in office business districts and residential quarters to build shaft-type underground parking garages under the public green space. [0003] At present, at home and abroad, in the small open space of residential areas, decentralized small-scale shaft-type intelligent underground garages (referring to automatic operation of scheduling, a...

AI Technical Summary

Problems solved by technology

[0004] At present, the construction method of the shaft-type underground parking garage requires the purchase of foreign excavation and excavation systems. The investment is huge, which increases the construction cost of the underground parking garage to a certain extent, and cannot be applied to complex stratum conditions, which inhibits the development of the shaft-type underground parking garage.
