Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It is to be understood that the block diagrams and specific examples are set forth herein for purposes of explanation only and are not intended as limitations on the present invention.
As shown in fig. 1, the utility model discloses gu soil slope protection structure divide into two parts, is first slope protection structure 1 and second slope protection structure 2 respectively. Wherein, first slope protection structure 1 is located the side slope and is close to bank side one side, and second slope protection structure 2 is located the side slope and is close to surface of water 24 one side. The ratio of the length of the first slope protection structure 1 to the length of the second slope protection structure 2 along the side slope ranges from 1:1 to 3: 2.
First slope protection structure 1 adopts cobble 12 as the bottom foundation, the last PE graticule 11 that tiles, as shown in fig. 2, the graticule is the netted material constitution of rhombus or hexagon unit interconnect, and cobble 12 is placed to the graticule bottom. The interior is backfilled with the raw soil of the side slope or other soils, and the ground grass vegetation 13 with the soil strengthening and slope protecting functions, such as tall fescue, clover, bermuda and the like, is planted. The pebbles with the specification and size of 80-120 mm can be selected as the pebbles, rhombus or hexagon with the side length of 300mm and the height of 500mm can be selected as the size of the grid, and the grid is completely covered and filled by the original soil, so that the grid is prevented from moving. Meanwhile, the pebbles fix the positions of the grids, and can also play roles in fixing slope soil and resisting water body scouring, and the root systems of the surface grass planted by the soil in the grids grow downwards through the gaps of the pebbles, so that soil loss is prevented.
The second side slope structure 2 is located below the first side slope structure 1 and is divided into 3 layers according to the direction perpendicular to the side slopes: the bottom layer is a bentonite layer 23, the middle layer is a building waste residue and straw layer 22, and the uppermost layer is a planting soil layer 21. The bottom layer uses bentonite as a foundation, and the bentonite can absorb water and expand after being applied into soil, so that the proportion of solid, liquid and gas in the soil can be changed, the soil structure is loosened, and the bentonite not only can retain water and fertilizer, but also does not pollute the soil environment, and is a commonly used soil conditioner. Meanwhile, the bentonite can form slurry by utilizing the lubricity, the bonding tightness, the thickening property and the gelling property of the bentonite, and has a compact waterproof effect. The bentonite layer may be 300mm to 500mm thick. The intermediate level adopts building waste residue and straw layer, and building waste residue adopts the less dregs of a dimensions, concrete piece, rubble piece, brick and tile fragment etc. of size specification, and size specification can be between 50-100 square millimeters, and the mixed soil layer of building waste residue and straw has the effect of better solid soil bank protection, and intermediate level thickness is 400 adding one's money 500 mm. Planting soil is laid on the uppermost layer, the thickness of the planting soil is 300-400mm, and aquatic plants such as grassleaf sweelflag rhizome, thaliana, iris and the like can be planted, so that the soil-fixing and slope-protecting effects of the plants are fully exerted.
The first slope structure and the second slope structure can be separated by a partition plate or a stepped platform.
The utility model discloses a sectional type structural design has avoided using large tracts of land concrete slope structure, has both saved engineering cost, also helps river course ecological maintenance, green. Meanwhile, building waste residues and straws are used as slope protection materials, so that secondary utilization of waste is realized, and environmental protection is facilitated. The method has universality for the side slopes of common medium and small river channels.
The utility model discloses a first side slope structure of firm soil slope protection structure also can divide into 3 layers according to the perpendicular to side slope direction: the bottom layer is a bentonite layer, the middle layer is a building waste residue and straw layer, and the uppermost layer is a planting soil layer. And the second side slope structure adopts measures such as stone masonry, dry stone or concrete pouring and the like to reinforce the river channel and the side slope.
The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
