Further, the upper end face of the asphalt sand is compacted to form a slope surface, and the slope surface is declined and inclined from the steel rail to the side of the track foundation pit.

Furthermore, the section of the steel reinforcement framework is in an inverted L shape, and the steel reinforcement framework is formed by assembling and welding a plurality of steel reinforcement strips which are transversely and longitudinally arranged.

Furthermore, edge protection angle steel is further arranged at the top angles of the two sides of the top of the track foundation pit respectively, and a plurality of edge protection angle steel anchor bars are welded and connected to the back of the edge protection angle steel and buried in the track ground.

Further, in the utility model, at least two layers of arc-shaped steel plates are stacked.

According to the utility model, through designing a new track structure, the bearing capacity of the steel rail for massive heavy transportation is greatly enhanced, meanwhile, the drainage from the rail is optimally designed, the influence of rainwater on the corrosion of the steel rail is reduced as much as possible, the whole new track structure is designed, the service life of the track structure is prolonged, the period and the workload of post maintenance are reduced, and the method has good practical use and popularization values.
