A construction method of underground shallow fully automatic parking garage

Abstract

The invention discloses a building method of an underground shallow layer fully automatic parking garage. The advantages of high speed and low engineering manufacturing price of an open-excavation method and the advantages of short foundation pit exposure time and fast pavement recovery of a cover-excavation method are integrated; the foundation pit earthwork adopts open-excavation construction; an underground structure is firstly constructed; an internal structure is constructed after the ground trafficability is recovered on a roof; the road-occupying construction range and the road-occupying construction time can be reduced; and the influence on the urban traffic is reduced.

Description

technical field [0001] The invention belongs to the field of construction of underground spaces such as underground cars, underground stations, and underground shopping malls under underground urban roads, and in particular relates to a construction method of an underground shallow fully automatic parking garage. Background technique [0002] At present, the construction methods of underground spaces such as subway stations, underground shopping malls, and underground garages under urban roads mainly include open-cut method, cover-excavation method and underground excavation method. The open cut method is suitable for a wide construction site, which has many construction work areas and low project cost, but it has a great impact on urban ground traffic and the surrounding environment. The cover-excavation method is suitable for the roads with heavy urban traffic and needs to ensure a certain traffic flow. The exposure time of the construction foundation pit is short, and the...

Problems solved by technology

The open and cut method is suitable for a wide construction site, with many construction areas and low project cost, but it has a great impact on urban ground traffic and the surrounding environment

The cover-excavation method is suitable for the roads with heavy urban traffic and needs to ensure a certain traffic flow. The exposure time of the construction foundation pit is short, and the road surface can be restored as soon as possible. However, it is difficult to deal with the horizontal construction joints of the structural concrete structure, and the underground excavation construction is difficult and expensive. High, the depth of excavation and pouring of linings in each division should comprehensively consider factors such as foundation pit stability, environmental protection, permanent structural form and concrete pouring operations
