Roadbed settlement deformation control system

Abstract

The invention relates to the field of railroad beds and especially relates to a roadbed settlement deformation control system. The system comprises foundation soil, a reinforced concrete U-shaped frame, a fixing mechanism, an extrusion mechanism, a railway mechanism, a drainage mechanism and a water absorption mechanism. The foundation soil is laid on a roadbed of a railway. The reinforced concrete U-shaped frame is fixedly embedded in the foundation soil. A frame mechanism is mounted in the reinforced concrete U-shaped frame; the frame mechanism comprises a high-strength horizontal steel plate and high-strength vertical plastic plates; and the high-strength horizontal steel plate is fixedly installed in the reinforced concrete U-shaped frame and is horizontally arranged, the two high-strength vertical plastic plates with the same specification are fixedly installed at the bottom of the high-strength horizontal steel plate, and the bottom ends of the two high-strength vertical plasticplates are fixedly connected with the inner bottom wall of the reinforced concrete U-shaped frame. The roadbed settlement deformation control system provided by the invention has an advantage of improving the stability of the base.

Description

technical field [0001] The invention relates to the field of railway roadbeds, in particular to a roadbed settlement deformation control system. Background technique [0002] At present, most railway subgrades are filled with bulk materials according to a certain degree of density and a stable slope ratio, supplemented by ballast slope protection. [0003] Due to the limited compaction of bulk materials and the current level of construction technology, large settlements will occur in the subgrade body, and the side slope of the subgrade (especially the side part) will collapse or subside. For high-speed railways built in coastal areas Generally speaking, too much rainwater often causes rainwater to infiltrate and cause foundation settlement. Sometimes when the foundation is not treated uniformly, the uneven settlement pressure of the railway subgrade strictly limits the application range of the railway subgrade form in high-grade railways. Therefore, it is necessary to prov...

[0003] Due to the limited compaction of bulk materials and the current level of construction technology, large settlements will occur in the subgrade body, and the side slope of the subgrade (especially the side part) will collapse or subside. For high-speed railways built in coastal areas In general, too much rainwater often causes rainwater to infiltrate and cause foundation settlement. Sometimes when the foundation is treated unevenly, the uneven settlement pressure of the railway subgrade strictly limits the application range of the railway subgrade form in high-grade railways.
