Embodiment Construction
[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0033] A kind of laying method that pushes the long steel rail into the groove at one time, please refer to Figure 1-5 , its invention point is, adopt following construction steps:
[0034] Preparation stage before S1 laying:
[0035] 1. If the tool rail has been laid in the working section, the operator will remove it in advance; if the tool rail is not laid in the working section, the second step operation will be carried out directly.
[0036] 1. Set transition rollers 3 at the connection between the existing track and the long rail 2 to be laid. The transition rollers are placed on the outside of the sleeper. Starting from the transition rollers, place a supporting roller 4 at intervals along t...

Abstract
The invention relates to a laying method for pushing a long rail into a groove at one time, the laying method adopts T11 long rail transporter to transport the long rail to the place where the long rail is to be laid, by using the transition drum arranged at the joint of the existing rail and the long rail to be laid, the supporting roller arranged between the sleeper holes along the route direction and the rail conveyor provided on the T11 long rail conveyor push the long rail onto the supporting roller, Then the long rail is erected by hydraulic lifting and shifting machine, and then the supporting roller and the transition roller are removed, the long rail is dropped into the rail slot, and the long rail is fixedly connected with the rail fastener to realize the laying of the long rail.The laying method reduces the consumption of tool rails and laying construction equipment, reduces the construction cost, and improves the construction efficiency.
Description
technical field [0001] The invention belongs to the technical field of railway construction and relates to the laying technology of long steel rails, in particular to a laying method of pushing long steel rails into grooves at one time. Background technique [0002] In the process of railway construction, such as the construction of Tianhuan Railway, the existing track laying scheme is to first fully lay the tool rails (25m / root), use the tool rails as the temporary driving track of the T11 long rail transport vehicle, and then unload the long rails (500m / piece), and finally remove the tool rail to replace the long rail. The laying of long steel rails in this way has the disadvantages of large engineering quantity, large occupation of tool rails, long occupation time and high construction cost. [0003] After searching the prior art, no technical solution similar to this patent was found. Contents of the invention [0004] The purpose of the present invention is to overc...
