Construction Technology of Railway Track Laying “Replacement Method”
The Railway Track Laying “Replacement Method” is a fast method to lay railway rails.
The standard rail adopts the railway track laying machine to lay the rail row. After the rail row is laid, the track is adjusted manually, and then the machine is used to repair the ballast. After reaching the initial stable state, the long rail welding and stress release and locking construction will be carried out, and finally the track will be repaired by a large machine. According to the design requirements of the line, it is planned to carry out 6 times of mechanical tamping and 6 times of dynamic stabilization to reach the speed of line opening.
The track laying construction technology of changing laying method: construction preparation → laying the bottom ballast → laying the track row → ballasting the whole track → changing the track by changing the track → ballasting the whole track → unit rail joint welding → large machine whole track → stress relief and seamless seam Road locking → track finishing and polishing → track inspection and acceptance.
