Exterior-covered waterproof construction method for subway station side walls with hanging plate girders

Abstract

The invention provides an exterior-covered waterproof construction method for subway station side walls with hanging plate girders. The method comprises the following particular steps that firstly, underground diaphragm walls, embedded bars, uplift piles and lattice columns are constructed; secondly, a first layer of an earthwork is excavated, and roofs of a subway station and a commercial real estate are constructed; thirdly, a second layer of the earthwork and a second last layer of the earthwork are continuously excavated, pouring of middle plates and the hanging plate girders of all layers of the subway station is completed, and waterproof treatment is performed before the middle plates and the hanging plate girders of all the layers are poured; fourthly, the bottommost layer of the earthwork is excavated, bottom plates of the subway station and the commercial real estate are constructed, waterproof structures at the bottom plates are constructed, and the station side wall at the bottommost layer is poured; fifthly, all layers of the hanging plate girders are sequentially removed in a chiseling mode from bottom to top, and the station side walls are sequentially poured after waterproof treatment is performed on the layers.

Description

technical field [0001] The patent of the present invention relates to a waterproof construction method for a subway station, in particular to a waterproof construction method for outsourcing the side walls of a subway station with suspended beams. Background technique [0002] As urban traffic congestion becomes more and more serious, subways, as one of the effective ways to solve this problem, are being used more and more, and subway stations are an important part of urban subways. The site selection of subway stations tends to be in densely populated areas, commercial centers, cultural centers, and traffic evacuation centers, which makes it more likely that subway stations will be integrated with commercial buildings, residential buildings in residential areas, and various underground pipelines. Greatly increased the difficulty of station construction. In order to reduce the impact on road traffic and the surrounding environment and at the same time reduce the project inv...

Problems solved by technology

The site selection of subway stations tends to be in densely populated areas, commercial centers, cultural centers, and traffic evacuation centers, which makes it more likely that subway stations will be integrated with commercial buildings, residential buildings in residential areas, and various underground pipelines. Greatly increased the difficulty of station construction

In order to reduce the impact on road traffic and the surrounding environment and at the same time reduce the project investment as much as possible, the cover-excavation method has become the best choice for the construction of the same type of subway station. However, this method is currently used for the integration of the subway station and the surrounding buildings. in, not much experience

The integrated cover-excavation construction of the subway station and the surrounding buildings and structures requires the use of a transitional suspension girder in order to balance the force on the station structural slab during the construction process (the suspension girder needs to be chiseled out later). How to ensure the structure of the suspension girder? The board is not leaking, there is no related research
