Product Description

 

 

 

Rail dowel is also called rail plastic sleeve,nylon dowel,plastic insert,concrete dowel, concrete insert, which is a counter-party fastener for a screw spike or anchor bolt.Rail Plastic dowel is pressed in concrete sleeper and assembled with sleeper screws, guide plates and rail clip to fix the rail. It is used to guarantee the good connection and linkage of the rail fastening system with the concrete sleeper, together with screw spikes or bolts.
In a set of rail fastening system, the rail dowel can be considered as the fastening foundation, as it needs to be pre-inserted into the concrete sleeper separately before assembling the rail fastening system parts.The rail dowel is used to guarantee the good connection and linkage of the rail fastening system with the concrete sleeper, with screw spikes or bolts.
The rail dowel's another function is to insulate the fastener parts from the ties. Therefore, the quality of this small pre-inserted part into the concrete sleeper, especially its strength and fatigue life, is of great importance to the whole rail line. Taking WJ-8 fastening system for an example, the collaboration of anchor bolts and imbedded rail dowel in the track slabs makes the tie plate be tightly fastened to rail and sleeper, through rail clips, to fulfill a enough elasticity range, to avoid the rail bolt against becoming loose, and decrease the maintenance work accordingly.
