Embodiment

[0039] Such as Figure 1-3 As shown, this embodiment provides a wading railway subgrade structure, including guide and interception device, water retaining wall 2, horizontal drainage pipe 11, ballast block 5, filling subgrade 1, reinforcement component 4, slope surface masonry closure 6. Anti-scouring foundation 7 and medium-coarse sand drainage layer 10;

[0040] The filling subgrade 1 is located on the ground, and the filling subgrade 1 is filled with fillers with good water stability.

[0041] The guiding and intercepting device is located at the periphery of the railway embankment, and is buried in the ground towards the water-facing side of the ground. The guiding and intercepting device includes a diversion dike 8 and a water intercepting ditch 9. The top of the diversion dike 8 protrudes from the ground, and the diversion dike 8 includes a retaining The water side 81, specifically, the diversion dike 8 is generally 0.5-1m higher than the ground, the embedding depth of...

Abstract

The invention discloses a wading railroad bed structure and a construction method thereof. The wading railroad bed structure comprises water retaining walls and transverse drainage pipes, the two water retaining walls are arranged on the two sides of a railway ballast respectively, the transverse drainage pipes are buried in a fill subgrade in the horizontal direction, the at least two transversedrainage pipes are arranged at intervals in the line direction, and the two ends of each transverse drainage pipe penetrate through the two sides of the fill subgrade respectively. The water retainingwalls can prevent flood from invading a ballast bed, flushing on the ballast, and influencing on railroad stability; the transverse drainage pipes provide a transverse channel for accumulated water on the ground surface, the situation that the stability of a railroad bed is affected due to the fact that surface water washes the railroad bed can be prevented, the operation and maintenance pressureof a drainage system of the railroad bed is relieved, and safety and stability of the railroad bed or a seasonal flood roadbed are guaranteed.

Description

technical field [0001] The invention relates to the field of railway engineering, in particular to a wading railway embankment structure and a construction method thereof. Background technique [0002] At present, in the design process of domestic railways, the design water level is generally required to be more than 1m higher than the fortified water level, so wading railways rarely appear. [0003] However, due to low fortification standards and years of human activities in the early domestic railways, wading railways appeared. my country has built many railways in Africa, where the terrain is flat, the soil is loose, the instantaneous rainfall is large, the soil erosion is serious, and the drainage system is prone to siltation and blockage; in addition, the awareness of railway protection in different countries is different, and the newly built water conservancy in the area near the railway is not compatible with the railway. Coordination happens multiple times. Although...
