Novel concrete fractionation device for subway slab track construction and construction method

Abstract

The invention provides a novel concrete fractionation device for subway slab track construction and a construction method. The fractionation device is installed on a steel rail above a track slab through walking wheels, the fractionation device can freely slide on the steel rail, and two fractionation chutes capable of freely moving are symmetrically arranged on the fractionation device through a sliding rail beam and a sliding block, so that accurate alignment of the fractionation chutes, a discharging opening and pouring holes is achieved, continuous pouring can be achieved, the problem of procedure interruption in a traditional construction technology is solved, and the construction efficiency is higher. Limiting devices are further arranged on the two sides of the fractionation device, the limiting devices are clamped with the pouring holes of the track slab through stopping blocks capable of moving up and down, then braking of the fractionation device is achieved, the risk that the fractionation device slides in the discharging process of an ash hopper and the pouring process of the fractionation chutes is avoided, operation is convenient, and 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...
