Embodiment Construction

[0018] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] like figure 1 , 2 As shown in and 3, the precision control device includes a transverse support plate 10, a longitudinal support plate 30, a vertical support plate 20, a horizontal adjustment device 50 and a longitudinal adjustment device 40, and the accuracy control device is symmetrically arranged on the newly paved track slab. 70, and fixedly connected with the track base plate 80. The longitudinal support plate 30 and the vertical support plate 20 are all welded on the two ends of the transverse support plate 10, wherein the longitudinal support plate is arranged along the direction of the track base plate, and the transverse support plate 10 is wider than the track base plate 80 and has enough strength, and through the vertical support plate 20 and the fastening screw 60 and the track base plate consolidated into one, the force t...

Abstract

The invention provides a precision control device and construction method for coarse laying of CRTS III type track boards. The precision control device comprises transverse supporting plates, longitudinal supporting plates, vertical supporting plates, transverse adjusting devices and longitudinal adjusting devices. The precision control device is fixed to a track base board through fastening bolts. The offsets of the track boards are controlled through the transverse adjusting devices and the longitudinal adjusting devices, and therefore coarse laying of the track boards is effectively positioned. The coarse laying positions of the track boards are effectively controlled, the track boards are generally laid beside a coarse laying line, labor for coarse laying of the track boards is reduced accordingly, time for finely adjusting the track boards is greatly shortened, and the construction period and overall efficiency are positively influenced.

Description

technical field [0001] The invention relates to the technical field of rough laying of track slabs for ballastless tracks, in particular to a precision control device and construction method for rough laying of CRTS III track slabs. Background technique [0002] With the vigorous development of high-speed railways, more and more high-speed railways adopt CRTSIII type track slabs with completely independent intellectual property rights in my country, accumulating more experience for high-speed railway construction, thus providing strong technology for my country's high-speed railway going global strategy Assure. In the self-compacting concrete construction of CRTSIII type slab ballastless track of high-speed railway, the rough laying accuracy of the track slab directly affects the fine adjustment workload of the track slab, which is an important link in determining the construction progress. In the rough paving process, a lot of manpower is often required to cooperate with th...
