Construction method of a shaft-type underground parking garage

Abstract

The invention relates to a construction method of a shaft-type underground parking garage, comprising the following steps: S1: driving uplift piles around the caisson or caisson; S2: grouting the piles to reinforce the uplift piles after pile formation, and enlarging the pile heads; S3: Drill bolt holes on the side of the uplift pile and embed guide rails; S4: Install steel corbels on the pre-embedded guide rails to install the weight balance system for vehicles entering and leaving the warehouse; S5: Pouring reinforced concrete on the ground Shaft; S6: Evenly excavate the caisson or caisson at the bottom section until the sinking is complete; S7: Jack the caisson or caisson; S8: Build the caisson or caisson at the second section, and continue to excavate the caisson or caisson The caisson is connected to the next section of the well wall; S9: after sinking to the design elevation, the foundation is cleared and the bottom of the caisson or caisson is sealed; S10: the design and capping of the construction well are carried out. Compared with the prior art, the present invention has the advantages of reliability, short construction period, economical and reasonable shaft-type underground parking garage excavation construction and the like.

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.
