Problems solved by technology

However, most of today's reinforcement materials rely solely on steel bars, geogrids and other strips or mesh ribs to improve the bearing capacity and anti-vibration subsidence capacity of the railway subgrade, but in fact these reinforcement materials lack toughness, and it is difficult to effectively control the subgrade vertical Deformation, and cause a substantial increase in construction cost

Embodiment Construction

[0024] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] Such as figure 1 As shown, the embodiment of the present invention provides a railway glass fiber reinforced loess roadbed, the roadbed is composed of glass fiber reinforced gray soil improved loess layer 1, gray soil improved loess layer 2, and compacted loess layer 3 from top to bottom .

[0026] The glass fiber reinforced gray soil improved loess layer 1 is a composite foundation combining two layers of steel-plastic geogrid and glass fiber reinforced gray soil improved loess. The gray soil improved loess layer 2 is formed of gray soil improved loess. The steel-plastic geogrid 4 used Two-way geogrid, with steel wire inside, its main ...

Abstract

The invention discloses a railway glass fiber ribbed loess roadbed and a construction method thereof. The roadbed is composed of a glass fiber ribbed orthod modified loess layer, an orthod modified loess layer and a compact loess layer sequentially from top to bottom, the glass fiber ribbed orthod modified loess layer is a composite foundation combining two layers of steel-plastic geogrids with glass fiber ribbed orthod modified loess, and the orthod modified loess layer is formed by orthod modified loess. Wet subsidence and vibration subsidence of the loess railway roadbed can be eliminated, compressive strength, shear strength and vibration strength of the loess railway roadbed can be improved obviously, later strength of the roadbed is improved obviously, and the railway glass fiber ribbed loess roadbed is simple to construct and relatively low in construction cost.

Description

technical field [0001] The invention relates to the technical field of railway subgrade reinforcement, in particular to a railway glass fiber reinforced loess subgrade and a construction method thereof. Background technique [0002] With the rapid development of the western region, in the northwest region where the loess is widely distributed, the transportation construction has developed significantly, and the railway, as a transportation hub connecting various cities, occupies a particularly important position in the transportation construction of the northwest region. In the loess area, due to the special properties of the loess, the railway road construction process will inevitably face the problems of loess subsidence and vibration damage. [0003] With the development of railway construction, the safe operation of railway trains has continuously increased the requirements for track smoothness, especially high-speed railways must have the characteristics of high smoothn...
