Problems solved by technology

[0002] The existing shoulders of the railway subgrade are provided with drain holes in the shoulder outside the cable trough, which is prone to the problem that the position of the drain hole of the cable trough is difficult to correspond to the drain hole of the shoulder guard or the construction is difficult. In addition, the drain hole of the shoulder guard does not drain well When it is smooth, it is easy to cause water accumulation inside the cable trough and on the surface of the subgrade bed inside the cable trough, which will cause water to seep into the subgrade body to cause muddying, erosion and hollowing of the subgrade bed, and frost heaving of the subgrade when the temperature is low, shortening the life of the subgrade. service life
At the same time, the construction process of traditional cast-in-place concrete shoulder protection is complicated, and the construction quality is difficult to control

Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing.

[0034] Such as figure 1 , shows a cross-sectional view of a railway shoulder disclosed in the prior art. The shoulder 10 of the railway roadbed is made of cast-in-place concrete, and when pouring concrete, drainage channels 11 and 12 need to be reserved, and the position of the drainage channel 11 needs to be Corresponding to the position of the drain hole 21 on the side of the cable trough 20, the construction is difficult, and the drainage channel 12 on the side of the permeable gravel layer is easily blocked by silt. In the case of the shoulder, the drainage channel 12 is dredged.

[0035] In the railway embankment, a leveling layer 40 is provided on the top of the bottom layer top surface 30 of the foundation bed, that is, a leveling layer 40 is provided between the top surface 30 of the bottom layer of the foundation bed and the cable trough. The bottom surface 50 of...

Abstract

The invention provides a railway road shoulder. The railway road shoulder comprises a cable trough; a permeable rubble layer arranged at the bottom of the cable trough and on one side close to a railway; a gabion shoulder pad arranged on one side, far away from the railway, of the cable trough, and permeable to water; wherein the bottom and the side surface of the cable trough are provided with drain holes communicated with the gabion shoulder pad, so that water in the cable trough can be drained through the drain holes and the gabion shoulder pad. According to the gabion road shoulder, accumulated water in the cable trough can be drained through the drain holes and the gabion shoulder pad, accumulated water in the roadbed can be drained through the permeable rubble layer and the gabion shoulder pad, and the drainage capacity is excellent.

Description

technical field [0001] The invention relates to the field of civil engineering facilities, in particular to a railway shoulder. Background technique [0002] The existing shoulders of the railway subgrade are provided with drain holes in the shoulder outside the cable trough, which is prone to the problem that the position of the drain hole of the cable trough is difficult to correspond to the drain hole of the shoulder guard or the construction is difficult. In addition, the drain hole of the shoulder guard does not drain well When it is smooth, it is easy to cause water accumulation inside the cable trough and on the surface of the subgrade bed inside the cable trough, which will cause water to seep into the subgrade body to cause muddying, erosion and hollowing of the subgrade bed, and frost heaving of the subgrade when the temperature is low, shortening the life of the subgrade. service life. At the same time, the construction process of traditional cast-in-place concre...
