Description
Technical Field
The invention relates to the technical field of highway side slope protection facilities, in particular to a vegetation slope protection method for a highway side slope.
Background
Because the highway is completely in the natural environment, the side slope of the highway is easily damaged by rain, snow and running water, and the vegetation can protect the slope, green the environment and improve the landscape effect of the highway. To the structure, the soil property, the state of different side slopes, can adopt skeleton grass planting bank protection, each room grass planting bank protection of geotechnique, hydraulic pressure spray seeding's grass bank protection, high steep side slope grass planting bank protection and TBS grass planting bank protection technology respectively, make the side slope so that the road bed keeps permanent good state, wherein the destruction of highway side slope mainly has two kinds of forms: firstly, the side slope is not stable enough and deforms slowly to cause final instability, namely integral or local landslide; and secondly, the side slope soil loss is caused by infiltration and erosion of rain, snow and running water on the side slope. At present, most highway subgrade side slopes adopt a grass planting protection method in a large quantity, and a good protection effect and an environmental landscape effect are achieved.
The three-dimensional vegetation net slope protection is developed on the basis of the defects that turf slope protection is easy to suffer from strong rainfall or slope runoff all year round forms gully, the instability and the slumping of the surface layer of the slope are caused, and the like, and has the following characteristics: and (1) the soil-fixing performance is excellent. The net bag with wavy surface has excellent fixing effect on soil, grass, etc. covered on the net and can reduce erosion of rain. And (2) the energy dissipation effect is obvious. The mesh covering layer buffers the impact energy of raindrops, weakens the splash erosion of the raindrops, enables wind, water flow and the like to generate countless small vortexes on the surface layer of the mesh surface, and slows down the wind erosion and the water erosion. And (3) the network reinforcement effect is outstanding. The transverse and vertical lines between the basic layer of the three-dimensional vegetation net and the net wrapping layer grids are woven and bonded in a staggered mode, so that the three-dimensional vegetation net has a reinforcement effect on backfilled foreign soil, and the erosion resistance of the surface layer of the side slope is improved along with the growth of grass root systems. And (4) the heat preservation function promotes vegetation growth. The temperature of the vegetation root can be 3-5 OC lower than the external environment temperature in summer and 3-5 OC higher in winter, so that the three-dimensional vegetation net prolongs the construction time of the roadbed tree-planted revetment to a certain extent and promotes the survival rate and uniform growth of vegetation.
In the actual three-dimensional vegetation net work progress, the pre-fixing of three-dimensional vegetation net is stable inadequately, and it is also comparatively difficult to the expansion of the three-dimensional vegetation net of large tracts of land, does not expand completely and arrange unstable three-dimensional vegetation net, can influence subsequent spray-seeding grass planting work's quality, also can lead to the phenomenon of partial region range upon range of extrusion simultaneously, influences the life and the maintenance cost of bank protection.
