Description

Steel rail arrangement structure for rail transit Technical Field The invention belongs to the technical field of railway design, and particularly relates to a steel rail arrangement structure for rail transit. Background The railway is a track line for vehicles such as trains to run, in order to improve the convenience of transportation, the length of the track line is generally long, rails of the railway can be damaged in different degrees during long-term running and rolling of the train, a rail inspection vehicle is required to be regularly used to inspect the rails in order to avoid the damaged rails from influencing the running safety of the train, and the performance of the rail inspection vehicle is also required to be inspected before the rail inspection vehicle is used, as shown in fig. 1, the current inspection means is to build two parallel rails, one uses the damaged rail and the other uses the undamaged rail, so that the rail inspection vehicle respectively passes through the two rails, and then whether the detection result is correct is checked. However, two parallel tracks occupy a large area, which increases the construction cost and wastes resources when the line utilization rate is not high. And the railway still can pass from the environment of difference, and current railway track construction only corresponds single circuit design parameter, the parameter of track just can not be adjusting after the track engineering construction is accomplished, the long-term use of railway can lead to some highway sections to appear not influencing the slight deformation of use, and overhaul the normal use that can influence the railway to these deformation departments, so can only slow down and walk slowly when the train goes here and pass through, and along with the rapid development of science and technology, the transport capacity and the speed of traveling of train have promoted greatly, and constantly slow down and accelerate and can make train life shorten, also influence the transport capacity of railway simultaneously. Therefore, it is necessary to design a staggered rail arrangement track structure to solve these problems Disclosure of Invention The invention aims to provide a steel rail arrangement structure for rail transit, which can realize the coexistence of railway lines with hedging parameters, meet the running requirements of different trains, simultaneously does not increase the occupied area and reduces the resource waste and the construction cost. In order to solve the technical problems, the invention adopts the technical scheme that: a steel rail arrangement structure for rail transit comprises a track bed and sleepers, wherein the sleepers are fixed on the track bed, steel rails A, steel rails B, steel rails C and steel rails D are arranged on the sleepers, the steel rails A and the steel rails B are parallel to each other to form a main track, the steel rails C and the steel rails D are located between the steel rails A and the steel rails B, the steel rails C are communicated with the steel rails B through first switch rails, the steel rails D are communicated with the steel rails A through second switch rails, the steel rails C and the steel rails A are parallel to each other to form first branch rails from the first switch rails, and the steel rails D and the steel rails B are parallel to each other to form second branch rails from the second switch rails. Preferably, the ballast bed is a ballast track or a ballastless track.
