Railway sleeper is one of the components of railway track. When in use, it is mainly connected directly at the rail bottom. To a certain extent, it can stabilize the position of the rail  prevent the rail  displacement  danger when the train passes. It can also distribute the pressure generated when the train passes through the ballast, so that the train operation is more stable.

The small compilation of railway track equipment shares the engineering characteristics of railway sleepers for you:

1、 The construction of railway sleepers requires the one-time laying speed of the jointless track,  the acceptance  delivery speed standard is 80km / h, which requires high stability  stability of the track  high construction technology.

2、 The construction technology of the original monolithic track bed of railway sleeper has been improved to a certain extent. The monolithic track bed shall be concreted at one time,  the buttress shall  be concreted.

3、 Difficulties in the construction of railway sleepers: the line is mainly Viaduct with a height of more than 20 meters, which is located in two highways, shopping malls, residential areas, road traffic intersections  other traffic congestion sections. The materials  equipment required for laying the line need to be hoisted to the bridge for operation. It is difficult for the materials to enter the bridge, the working face is limited, the bridge transportation is heavy,  the safety protection under the bridge is difficult.

4、 There are 12 Construction breakpoints, with a length of 200-400m, resulting in continuous operation of track engineering construction. After section construction, construction tools  mechanical equipment can be transported to increase labor intensity.

During the operation of railway sleepers, the 25m rail is directly welded to the unit rail joint on the line by the mobile contact rail welding car. Rail welding equipment is matched with rail car  flat car. Heavy vehicle weight, large gradient  large curve radius make rail welding more difficult.

The rail damping fastener  short sleeper of railway sleeper, DT Ⅵ 2 type fastener  short sleeper are  concentrated enough on the line,  there are many sections, resulting in a large number of support tools reshipment. Due to the long construction time span, cold construction in winter  high temperature construction in summer, different measures must be taken in the concrete pouring construction to ensure the construction quality.
