Embodiment Construction

[0019] The ballast-free high-speed railway of the present invention mainly consists of steel rail 4, railway rectifying plate 2, anti-rust and anti-wear layer 5, reinforced concrete strip 3, ballast stone layer 6, ballast stone limit plate 1, electrification facilities, isolation belt and foundation 10 and so on.

[0020] The top of the foundation of the present invention is embedded with crushed stones and paved with a seepage-resistant layer composed of asphalt and sandstones, on which ballaststones are piled up, and ballaststone limiting plates 1 are arranged on the slopes on both sides of the ballaststones. The reinforced concrete bar 3 is arranged on the top of the ballast layer 6 along the running direction of the train, and the railway rectifying plate 2 is covered thereon. The rail 4 is combined with the railway rectifying plate 2 and the reinforced concrete bar 3 through a gasket screw and the like.

[0021] An anti-rust and anti-wear layer 5 is provided between the ...

Abstract

The invention relates to a high speed railway without clear ballasts. The railway comprises steel rails, railway rectifying boards, rust and wearing resistant layers, reinforced concrete bars, ballast layers, ballast limiting boards, electric facilities, isolation belts and a foundation. The railway is characterized in that the steel railway rectifying boards are arranged below the steel rails. The relationship between the railway and motor trains is comprehensively considered, the high speed railway is scientifically classified, and through the railway rectifying and the corresponding appropriate reinforcement, the resistance reduction and energy saving can be achieved, so that the high speed railway without clear ballasts is very practical and low in price, and can be widely applied to construction and speed-up reconstruction of railways.

Description

technical field [0001] The invention belongs to the technical field of railway construction. Background technique [0002] The railway with heavy ballast stacked under the rails has the dual advantages of load bearing and shock absorption. Therefore, no matter whether it is an existing line reconstruction or a new line, the lines on which bullet trains travel are generally dominated by ballast tracks to accommodate both passenger and freight transportation. need. However, the gravel is stacked in a trapezoidal shape without restraint, and the maintenance work is extremely heavy. Especially after the speed of the EMU reaches 250 kilometers per hour, a strong cyclone will form at the rear of the car belly, and the gravel will be lifted up, causing great danger to the train operation. For this reason, the high-speed rail industry has mechanically fixed a speed of about 250 kilometers per hour as the dividing line between ballasted and ballastless, and as the dividing line bet...
