Drainage roadbed for preventing railway fill road shoulders from sliding and fracturing and production process of drainage roadbed

Abstract

The invention discloses a drainage roadbed for preventing railway fill road shoulders from sliding and fracturing and a production process of the drainage roadbed. The drainage roadbed comprises a main roadbed body, a railway fixing transverse plate, transverse plate bolts, roadbed fixing seats, anti-slide and anti-fracturing road shoulders and road shoulder fixing seats; the main roadbed is composed of an upper concrete layer and a lower concrete layer; rainwater passes through a filling groove, a through hole and a drainage hole, so that the rainwater is discharged to a middle-layer water channel; the anti-slide and anti-fracturing road shoulders on the two sides are formed by sequentially stacking a soil layer, a waterproof coating, an anti-fracturing brick layer, a waterproof coating and a reinforcing layer and pouring a concrete shell on the outer side, the anti-sliding and anti-fracture capacity of the road shoulder parts is effectively improved; if the concrete shell cracks, thereinforcing layer and the anti-cracking brick layer continue to maintain the supporting force on the main roadbed, the accident that a railway track inclines and collapses due to deviation of the main roadbed is prevented, the probability of sliding and fracture is effectively reduced, the drainage capacity is high, and applicability is wide.

Description

technical field [0001] The invention relates to the technical field of drainage roadbed, in particular to a drainage roadbed and a production process thereof for preventing the sliding and cracking of railway fill shoulders. Background technique [0002] The roadbed is a structure that directly supports the track formed by filling or excavation. It is also called the substructure of the line. The roadbed is connected with bridges and tunnels to form a line. The roadbed has two basic forms according to its different topographical conditions. They are embankment and cutting, commonly known as filling and excavation. The function of railway subgrade is to lay track structure directly on the subgrade surface, so the subgrade is the foundation of the track. The dynamic load transmitted through the track, the line structure formed by the subgrade and the track together is a relatively loosely connected structural form, and the ability to resist the dynamic load is weak. Therefore...

[0002] The subgrade is a structure that directly supports the track formed by filling or excavation, also called the substructure of the line. The subgrade is connected with bridges and tunnels to form a line together. The subgrade has two basic forms depending on the terrain conditions. They are embankment and cutting, commonly known as filling and excavation. The function of railway subgrade is to directly lay track structure on the subgrade surface, so the subgrade is the foundation of the track. The subgrade load bears the weight of the track structure, that is, the static load, and also bears the train running When the dynamic load transmitted through the track, the line structure formed by the subgrade and the track together is a relatively loosely connected structural form, and the ability to resist dynamic load is weak. Therefore, the roadbed is a kind of geotechnical structure, which is often attacked and damaged by changes in natural conditions such as geology, water, rainfall, climate, and earthquakes, and has poor resistance. Therefore, the roadbed should have sufficient firmness, stability and durability. , for high-speed railways, the subgrade should also have reasonable rigidity to ensure the stability and comfort of trains running at high speed. Landslides are prone to occur after rainwater washing, causing the railway track to tilt and collapse. After a long time of use, the pure concrete shoulder is prone to sliding and fracture, which will also cause the railway track to tilt and collapse. At the same time, the drainage capacity of the railway subgrade is poor, which affects the railway track. normal operation of the
