Abstract

The invention discloses a horizontal cutting device for arching of a track plate of a ballastless track bed and a construction method thereof. The device comprises a vertical cutting device, a horizontal cutting device body and a temporary fixing device, wherein the vertical cutting device comprises vertical cutting positioning wheel holes formed in bottom plates on the left and right sides of the portion, at the apex of the arch, of the track plate, vertical cutting positioning frames arranged at one sides of the vertical cutting positioning holes, vertical cutting positioning wheels arranged on the vertical cutting positioning frames, guide wheel sets, driving wheels and sawing ropes connected with the driving wheels; the sawing ropes are matched with the guide wheel sets and the driving wheels mutually to form a loop; the horizontal cutting device body comprises horizontal cutting construction grooves respectively formed closely adjacent to the bottom plates at the two sides of the track plate, horizontal cutting positioning wheels installed at the horizontal cutting construction grooves, guide wheel sets, driving wheels and sawing ropes connected with the driving wheels; and the temporary fixing device comprises a temporary flexible base plate and a temporary locking device. The method comprises the steps of drilling the vertical cutting positioning wheel holes, vertically cutting, forming the horizontal cutting construction grooves, horizontally cutting, temporally fixing, fixing the track bed and fine adjusting the path.

Description

technical field [0001] The invention relates to the field of track engineering, in particular to a device and a construction method for horizontally cutting an arch on a track slab of a ballastless ballast bed. Background technique [0002] In railway tunnels, due to complex geological conditions, under adverse conditions such as high ground stress, weak surrounding rock, expansive surrounding rock, and groundwater pressure, if the unfavorable geology is not effectively treated, it is easy to produce arching defects on the track slab of the ballastless ballast bed, which affects driving safety. [0003] The ballastless track is an integral ballast bed, and it is difficult to control its crowning disease. At present, the usual method is to treat and reinforce the base, supplemented by drainage and other measures to control the disease, and reduce the crowning amplitude. When the crowning amplitude is ≤ 6mm, it can be used The way of track adjustment is to reduce the elevation...
