Suspension-type tying moulds, reinforced cages for subway track beds and their application

Abstract

The invention discloses a suspension type metro subgrade reinforcement cage binding jig and application thereof. The suspension type metro subgrade reinforcement cage binding jig is characterized in that a cross arm is erected on the rail surfaces of a pair of steel rails which are positioned and serve as supports; two sides, on the pair of steel rails, of the cross arm extend out to form overhanging sections; vertical hooks are hung on the cross arm; upper-layer longitudinal ribs in a reinforcement cage are fixedly bound on the vertical hooks in a suspending manner; stirrups are fixedly bound on the upper-layer longitudinal ribs, and lower-layer longitudinal ribs are fixedly bound on the stirrups, so that a suspension type metro subgrade reinforcement cage is formed. According to the suspension type metro subgrade reinforcement cage binding jig, overall lifting and dropping of the reinforcement cage are directly avoided, so that deformation of the reinforcement cage is avoided, and the engineering quality is effectively guaranteed. The process of the method is simple and quick, and the construction efficiency can be substantially improved.

Description

technical field [0001] The invention relates to subway track bed construction, more specifically to a subway track bed reinforcement cage binding tire and its application. Background technique [0002] With the continuous development of the urbanization economy, the increase of population density, and the continuous increase of travel occurrence, the traffic tension has become increasingly prominent. With its fast and comfortable features, the subway has gradually become an effective way to solve these problems. In my country, the construction of urban rail transit is in a peak period. While ensuring the construction quality, improving construction efficiency and reducing construction costs are strong guarantee measures for subway construction. [0003] The binding of the steel bars of the subway track bed is a very time-consuming work in the construction of the subway track bed. The track project of the 10702 bid section of the Chongqing Metro Line 10 undertaken by the Cho...

Problems solved by technology

[0003] The binding of the steel bars of the subway track bed is a very time-consuming work in the construction of the subway track bed. The track project of the 10702 bid section of Chongqing Metro Line 10 undertaken by the Chongqing Metro Project Manager Department of the No. 8 Branch of the China Railway No. The traditional method of bundling steel bars on the overall ballast bed is to bind the steel bars on the base surface. After the bundling of the steel cages is completed, the steel cages are lifted up as a whole. However, due to the large volume, the overall lifting of the steel cages is very easy. The deviation of the spacing of the steel bars will cause deformation of the overall steel cage, which will affect the construction quality and increase the construction cost
