Technical Field
The utility model relates to a side slope engineering, concretely relates to side slope water storage greening structure.
Background
With the progress of society, environmental protection has become a very important issue. The slope engineering greening relates to the treatment of a hydro-fluctuation belt in a three gorges reservoir area, the restoration of abandoned mine environment, municipal engineering, road and railway engineering, building engineering and the like. For steep slope engineering, greening has two problems: soil lacking plant growth; the supply of water is lacked. Therefore, a great part of slope engineering is in a non-greening state and cannot enter the green mountain green water grid, and the ecological natural environment is seriously damaged.
In recent years, some new technologies have emerged to the problem of slope greening, such as: spraying grass seed concrete on the surface of the slope, stacking bagged soil, arranging planting grooves and the like. However, the grass seed concrete spraying technology is only suitable for gentle slope regions, and is thin (about 20 cm), and poor in water retention capacity; the greening technology of the stacked bagged soil slope is also influenced by the slope gradient and is not suitable for a steep slope; the method of arranging planting grooves on the slope can prevent the loss of planting soil on the steep slope, but the method still cannot provide the water retention capacity required by the plants.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a side slope water storage greening structure that water retention capacity is excellent.
In order to achieve the above purpose, the present invention adopts the following technical solution.
The side slope water storage greening structure consists of a planting container, a water drainage hole, a water storage layer, a water filtering layer, a water adsorbing material and a planting layer, wherein the planting container is fixed on the surface of a side slope and used for accommodating the water storage layer, the water filtering layer, the water adsorbing material and the planting layer. In the planting container: the water storage layer is placed in the lower part space, and the drainage layer covers on water storage layer upper portion, and the wash port setting is in planting the layer bottom and is located drainage layer surface height position, and the planting layer is placed in space more than the drainage layer (drainage layer is between above the water storage layer promptly, below the planting layer), and water adsorption material distributes in the water storage layer, and the drainage layer is connected on water adsorption material upper portion, and the lower part extends to planting container bottom.
Further: the water storage layer can be sand pebbles with large void ratio (the large void ratio is selected/screened by a person skilled in the art according to experience) or other materials with strong water storage capacity; the water filtering layer can be geotextile or other water filtering materials, and allows water to pass through but prevents the planting layer material from moving downwards to enter the water storage layer; the water adsorption material is of a strip or sheet structure, can be geotextile, and can also be other materials with water adsorption effect, so that water in the water storage layer can be conveniently upwards adsorbed to enter the planting layer.
Further: the filling material in the water storage layer can be omitted, but the upper water filtering layer needs to be structurally supported; the planting layer is made of a material suitable for plant growth, but is not limited to soil; the thicknesses of the planting layer and the water storage layer are comprehensively determined according to the characteristics of plants and the planting layer, the climate and the engineering conditions.
Further: the front end of the slope supporting structure is positioned at the bottom of the planting container.
Further: a plurality of planting containers are arranged at intervals on the side slope, and the suspended side bottom of a higher planting container (which can be called as an upper-level planting container) is projected into a lower planting container (which can be called as a lower-level planting container) adjacent to the higher planting container, so that water overflowing from the higher planting container can flow into the lower planting container adjacent to the higher planting container, and waste of water resources is avoided.
Has the advantages that: the utility model arranges a water storage structure in the slope planting container, which can greatly improve the water retention capacity of the slope planting soil body; the utility model has the advantages of low cost, short construction period, simple structure, easy implementation and the like, can fully utilize natural rainfall or reduce the frequency of artificial irrigation, and improves the drought resistance of slope greening; the utility model discloses a solve present wide-angle side slope can not the sustainable important link of afforestation problem, have splendid market prospect and social. Furthermore, the utility model discloses still have the advantage of making things convenient for artifical irrigation, only need irrigate at the side slope top during irrigation, stop when the planting container wash port play water of side slope bottom.
Drawings
FIG. 1 is a schematic sectional view of a water storage and greening structure for a side slope provided by the present invention;
in the figure, 1-planting container, 2-drain hole, 3-water storage layer, 4-water filtering layer, 5-water adsorption material, 6-planting layer and 7-side slope supporting structure.
Examples
The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the following description of the embodiments is only for the purpose of helping understanding the principle and the core idea of the present invention, and is not intended to limit the scope of the present invention. It should be noted that modifications to the present invention may occur to those skilled in the art without departing from the principles of the present invention and are intended to fall within the scope of the appended claims.
The method comprises the following steps: in arid regions, a rocky slope is shown in figure 1, and slope surface greening is required.
The implementation mode is as follows: selecting proper greening plants, determining the thickness of the planting layer 6 according to the plant root system and soil characteristics, and determining the thickness of the water storage layer 3 according to slope engineering and climate conditions; designing a slope water storage greening structure into a groove-shaped planting container 1, and fixing the planting container on the surface of a slope as shown in figure 1; when raining or artificial irrigation is carried out, water permeates into the water storage layer 3 through the planting layer 6 and is stored; the water in the water storage layer 3 is fully discharged through the water discharge hole 2 and flows into the next-stage groove type planting container 1; in the non-water supply period, the water absorption material 5 absorbs water in the water storage layer 3 upwards and enters the planting layer 6 to be absorbed by the plants.
The implementation steps are as follows:
step 2, selecting proper greening plants and materials of the planting layer 6, and comprehensively determining the thicknesses of the planting layer 6 and the water storage layer 3 according to the characteristics of the plants and the planting soil, the climate and the engineering conditions;
