Embodiment Construction

[0026] see figure 1 , figure 2 , a gauge correction device for double-block ballastless track construction, comprising two main girders 1, two sub-beams 2 parallel to each other are arranged at the two ends close to the main girders, and the main girders are connected in parallel to form Similar to the well-shaped layout; each main beam is equipped with a telescopic device in the middle to adjust the length of the main beam. Below each sub-beam, there are front and rear supporting running wheels 4 placed on the tool rail 10, and a pair of gauge correction wheels symmetrical to the sub-beam are arranged on the bottom near the end of the main beam through the wheel shaft, including placing them on the outside of the tool rail. The inner pull wheel 6 and the outer support wheel 5 placed on the inner side of the tool rail. The telescopic device can be composed of a telescopic sleeve 3 with positive and negative threaded bolts,

[0027] The main and auxiliary girders of the gau...

Abstract

The invention discloses a track gauge correction method for double-block type ballastless track construction. The method comprises the following steps of: (1) manufacturing a track gauge correction device; (2) adjusting the track gauge accuracy of the track gauge correction device by using a tool track of a group of track panels; (3) correcting a track gauge in construction, properly loosening fastener screw spikes before the track panels are raised, inserting the track gauge correction device from the start end of the tool track to press four pairs of track gauge correction wheels against two sides of the track wrist of the tool track, arranging supporting traveling wheels on the track surface of the tool track, longitudinally moving the device along the tool track, arranging a sleeper between front and back track gauge correction wheels to enable the track gauge correction wheels to apply force to the tool track so as to realize track gauge correction, manually screwing the fastener screw spikes, and fixing a track gauge relationship between the tool track and the sleeper to complete the track gauge correction operation of the sleeper; (4) sequentially performing the track gauge correction operation, in the step (3), on all sleepers.

Description

technical field [0001] The invention relates to the construction technology of ballastless track of high-speed railway, in particular to a gauge correction device and method in the construction of double-block ballastless track. Background technique [0002] CRTS-I type double-block ballastless track is a domestic ballastless track system formed on the basis of the introduction of German radar 2000 technology and combined with my country's national conditions. Compared with other forms of ballastless track, it has low cost and high work efficiency. , good durability and so on. After the Wuhan-Guangzhou Passenger Dedicated High-speed Railway (design speed 350km / h) was officially completed and opened to traffic in 2009, high-speed passenger dedicated lines such as Daxi, Lanxin, Shanghai-Kunming, Qingrong, etc., as well as large tunnels, station arrival and departure lines, etc. Line promotion application. At present, CRTS-I double-block ballastless track has become one of the...
