Railway solidified and closed ballast bed and solidification and closing method

Abstract

The invention relates to a railway solidified and closed ballast bed and a solidification and closing method. The railway solidified and closed ballast bed comprises ballast blocking walls, filling materials and an anti-crack concrete layer, the ballast blocking walls are arranged on the two sides of the railway ballast bed respectively, the filling materials are arranged in the ballast bed, and the anti-crack concrete layer is arranged at the top of the ballast bed. The solidification and closing method of the railway ballast bed comprises the following steps of ballast bed clearing and screening, ballast blocking wall pouring, ballast bed tamping and ballast bed closed pouring and solidification. The ballast blocking walls and ballast bed ballast can form a firm whole conveniently, conveyed materials can be cleared up, loaded and unloaded conveniently, the ballast bed of a railway line is closed, it is guaranteed that the ballast bed is firm, it can be guaranteed that the materials passing through a railway cannot be scattered on the ballast any more, meanwhile, the materials scattered on the railway line in the transportation, loading and unloading process can be cleared up conveniently, waste is reduced, and environmental sanitation is guaranteed.

Description

technical field [0001] The invention relates to a railway solidified and closed track bed and a solidified and closed method, belonging to the railway transportation industry. Background technique [0002] Most of the railway lines such as railway yards, freight yards, and power plants are laying stone ballast on the roadbed at present, and then laying sleepers and rail structures. Due to the gaps between the ballast, especially in the coal unloading line, when the granular materials on the vehicle are unloaded, many materials fall into the ballast and cannot be cleaned, which not only causes great waste, but also causes ballast pollution and affects the line. Stablize. For this reason, at present some coal field railway special lines directly make the ballast bed into concrete, but because there is no ballast, the ballast bed loses its elasticity, which affects the smooth running of vehicles, and easily causes damage to rails and wheels. [0003] With the advancement of h...

AI Technical Summary

Problems solved by technology

However, the integrated ballast bed transformed from high-speed rail technology requires high construction technology and huge investment. It is wasteful for special lines such as freight yards, stations, and power plant unloading coal compared to their transportation speed.

For the dedicated lines of railway stations, freight yards, and power plants that have been built, the reconstruction needs to be completely dismantled and cleaned before construction. The construction period is very long and the investment is huge, which will seriously affect the normal production and transportation order.
