Completely-assembled metro station double-column body structure and construction method thereof

Abstract

The invention discloses a completely-assembled metro station double-column body structure. A structure part of the completely-assembled metro station double-column body structure comprises a bottom plate block A for hoisting and positioning. The two sides of the bottom plate block A are connected with bottom corner plate blocks B. The bottom corner plate blocks B are provided with side wall blocksC. Two lower columns Z2 are fixed to the middle portion of the bottom plate block A. A left middle plate block D is fixed to the left side wall block C and the left lower column Z2. A right middle plate block D is fixed to the right side wall block C and the right lower column Z2. The left middle plate block D and the right middle plate block D are provided with an upper column Z1, the upper column Z1 is provided with a top plate block F, and top corner plate blocks E are fixed to the two sides of the top plate block F and the end portions of the side wall blocks C. The method part comprisesthe following steps that a first body structure is spliced and a second body structure is spliced till whole station splicing is finished. According to the completely-assembled metro station double-column body structure, through rebate connector and bolt connection, shearing force and bending moment of the connector part can be effectively resisted.

Description

technical field [0001] The invention belongs to a subway structure, in particular to a fully assembled double-column main structure of a subway station and a construction method thereof. Background technique [0002] At present, civil engineering costs in the construction of urban rail transit account for about 35% of the total investment, and most of them are tunnels and underground projects. The construction of interval tunnels has basically achieved standardization, factoryization, and mechanization through the use of shield technology. The traditional construction method is still adopted, that is, a large amount of construction materials such as cement and steel are still used for on-site construction. There is a serious lag in the development of construction technology and equipment. The construction quality, construction efficiency, operating environment, and standardization level are low. The construction period is long and the risk is high , The outstanding problems ...

[0002] At present, civil engineering costs in the construction of urban rail transit account for about 35% of the total investment, and most of them are tunnels and underground projects. The construction of interval tunnels has basically achieved standardization, factoryization, and mechanization through the use of shield technology. The traditional construction method is still adopted, that is, a large amount of construction materials such as cement and steel are still used for on-site construction. There is a serious lag in the development of construction technology and equipment. The construction quality, construction efficiency, operating environment, and standardization level are low. The construction period is long and the risk is high , Large environmental impact, low degree of industrialization and automation, outstanding problems, do not meet the requirements of industrial development
