Embodiment 1

[0035] In the embankment section, the first 100mm of the third road shoulder block 3 is placed on the embankment trim 9 , and the rear 200mm is placed on the bed filler 8 . The accumulated water in the cable trough 4 flows to the permeable gravel layer 5 through the drain hole at the bottom, and is discharged through the drain hole of the third road shoulder block 3, and flows into the slope drainage system.

Embodiment 2

[0037] In the cutting section, the first 100 mm of the third road shoulder stopper 3 is located above the cutting side ditch 10 , and the rear 200 mm is placed above the bed filler 8 . The accumulated water in the cable trough 4 flows to the permeable gravel layer 5 through the drain hole at the bottom, and is discharged through the drain hole of the third road shoulder block 3, and flows into the cutting side ditch 10.

Abstract

The invention provides a novel railway road shoulder structure and a construction method. The structure comprises a first road shoulder stop block, a second road shoulder stop block, a third road shoulder stop block and foundation bed filler; the third road shoulder stop block is of a cuboid structure, and drain openings are symmetrically formed in two sides of the bottom of the third road shoulder stop block; the second road shoulder stop block is arranged above the third road shoulder stop block; the vertical section of the second road shoulder stop block is in a right trapezoid shape; the first road shoulder stop block is arranged at the top of the second road shoulder stop block; the inner side of the bottom of the third road shoulder stop block is arranged on the foundation bed filler; waterproof geotextile is arranged on the foundation bed filler on one side of the third road shoulder stop block, a permeable sand gravel layer is arranged at the top of the waterproof geotextile, acable trough stop block is arranged on one side, close to the foundation bed filler, of the cable trough, and the cable trough is separated from the foundation bed filler through the cable trough stop block and the permeable sand gravel layer. According to the invention, a user can build the railway shoulder more conveniently and efficiently, the construction difficulty is greatly reduced, and the attractive effect of the road shoulder is improved.

Description

technical field [0001] The invention belongs to the field of railway embankment engineering, and in particular relates to a novel railway shoulder structure and a construction method. Background technique [0002] In the prior art, when the cable trough is set on the shoulder of the railway subgrade, the outer side of the cable trough needs to be provided with a shoulder guard, the top width of the shoulder guard is 10cm, the slope ratio is 1:0.5~1:1.4, and the bottom width is 45~108cm. Due to the small top width, slow slope and the need to reserve drain holes in the middle and bottom, the formwork is easy to skew, especially in embankment areas, resulting in uneven slopes and affecting the appearance; at the same time, the drain holes in the middle and cables The grooves are not easy to align, which affects the drainage effect. [0003] At present, some high-speed railway shoulders and drainage structures have appeared in China, such as high-speed railway shoulders and dra...
