Description

Technical Field

[0001] The utility model relates to the technical field of roadbed, in particular to a highway gangue roadbed structure. Background Art

[0002] Gangue is a major waste product of coal. It has stable mechanical properties and does not cause environmental pollution. Therefore, it has become a common practice to use gangue as road earthwork. However, there are gaps between gangue particles, which makes it easy to collapse when bearing vehicle loads. It is not suitable to be directly used as a roadbed material. Therefore, in order to fill the gaps in the roadbed and enhance its stability and carrying capacity, it is necessary to mix the gangue with cement and compact it by rolling to form a gangue rolled roadbed. The gangue rolled roadbed can effectively fill the gaps in the roadbed by filling cement slurry between the gangue particles, increase the density and stability of the roadbed, which can not only ensure the flatness and stability of the road, but also prevent the subsidence or abnormal slope of the roadbed material.

[0003] For example, application number: CN202020767361.X involves a highway gangue roadbed structure, including a filling layer group located on the upper side of the base, the filling layer group is composed of a number of filling layers arranged in sequence from bottom to top, a edging soil layer is arranged on the outside of the filling layer group, located on the lower side of the edging soil layer, and connected to the bottom filling layer with a number of blind ditches; the filling layers of the filling layer group are arranged in a stepped manner from bottom to top; each filling layer includes a large particle size layer located at the bottom and a small particle size layer located at the top; the particles used in the large particle size layer and the small particle size layer are all gangue particles. The beneficial effect of the utility model is that in the case of shortage of traditional material sources for roadbed filling, it is creatively proposed to use coal gangue waste materials near the line for roadbed filling, and a coal gangue widening roadbed structure is designed, which creates obvious economic benefits, practices the environmental protection concept of recycling, solves the thorny problem of filler shortage, and forms good comprehensive benefits.

[0004] Based on the above and the common coal gangue roadbed structures of highways on the market, when using cement slurry to fill the gaps in the coal gangue, the addition is not uniform enough, and some positions will cause the cement slurry to be unable to enter the gaps, and the cement slurry needs a long time to fully penetrate, affecting the construction efficiency. The edge positions of the coal gangue roadbed structure are prone to deformation or collapse after encountering heavy pressure, affecting the strength of the highway. Utility Model Content
