New Concrete Separating Device and Construction Method for Subway Slab Track Construction

Abstract

The invention provides a new type of concrete separation device and construction method for subway slab track construction. The separation device is installed on the rail above the track slab through traveling wheels, the separation device can slide freely on the rail, and the separation device passes through The slide rail beam and the slider are symmetrically equipped with two freely movable sub-chutes to achieve precise alignment between the sub-chute and the feeding port and the pouring hole, and can realize continuous pouring, which solves the problem of process interruption in the traditional construction process and improves the construction efficiency. higher. There are limit devices on both sides of the separation device. The limit device uses the stop block that can move up and down to realize the clamping connection with the filling hole of the track plate, and then realizes the braking of the separation device, avoiding the discharge of the ash hopper and the separation of the chute. There is no risk of the slipping device slipping during the filling process, the operation is convenient, and the use is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of construction tooling for subway slab track beds, and in particular relates to a novel concrete separating device and construction method for subway slab track construction. Background technique [0002] The slab track of the high-speed railway has the advantages of good line smoothness, high stability of the ballast bed structure, simple construction process, high degree of mechanization, fast construction progress, good visual quality, less difficulty in later maintenance and reconstruction, and good visual quality. Therefore, more and more urban rail transits have begun to explore the introduction of slab tracks. However, the construction technology of slab tracks is quite different from traditional cast-in-place tracks. Compared with high-speed rail, subways have poorer working conditions and narrow construction spaces. The design requirements of machinery and tooling are relatively high, and it is dif...
