Abstract

The invention discloses a construction method of a device for horizontally cutting an arch on a track slab of a ballastless ballast bed. The positioning wheel hole, the vertical cutting positioning frame installed on one side of the vertical cutting positioning wheel hole, the vertical cutting positioning wheel installed on the vertical cutting positioning frame, also includes the guide wheel group, the driving wheel and the connected saw rope, saw The rope cooperates with the guide wheel group and the driving wheel to form a loop; the horizontal cutting device includes horizontal cutting construction grooves respectively arranged on the bottom plates on both sides of the track plate, and horizontal cutting positioning wheels installed in the horizontal cutting construction grooves. It also includes a guide wheel set, a driving wheel and a connected saw rope; a temporary fixing device, including a temporary flexible backing plate and a temporary locking device. The construction method includes drilling and setting the vertical cutting positioning wheel hole, vertical cutting, construction horizontal cutting construction groove, horizontal cutting, temporary fixing, fixing the ballast bed and fine-tuning the line.

Description

technical field [0001] The invention relates to the field of track engineering, in particular to a construction method of a device 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 ...
