Which methods can effectively solve the thermal expansion and contraction of steel rails

Any item is subject to thermal expansion and contraction, and steel rails are no exception. What methods are there to solve the thermal expansion and contraction of rails? Let's take a look together.

First, determine the "locking rail temperature" according to local weather conditions. When the rail temperature is locked, the seamless track is fixed on the sleeper and bed with fasteners; the fixing force is greater than the force of thermal expansion and contraction; the rails are not allowed to expand or contract. The long rail is welded to the long rail, which needs to be polished and then polished as a whole.

The method of fastening with fasteners is to replace the spring fasteners with spring fasteners (also called spring fasteners), fasten the steel rails tightly to the sleepers, and forcefully digest the energy generated by thermal expansion and contraction. It is necessary to drill several holes in the steel rails waist within a certain distance to release the energy generated by thermal expansion and contraction, and retain the steel rails joints within a certain distance (about 1500m) to assist in releasing the energy generated by thermal expansion and contraction. Solve the problem of steel rails thermal expansion and contraction.
