Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of compression and impact resistance of silt slopes, and more specifically to a high-strength compression and impact resistance vegetation planting construction structure for silt slopes. Background Art
[0002] Silt refers to soil with a particle size greater than 0.075mm and a content of particles not exceeding 50% of the total amount, and a plasticity index IP ≤ 10. It does not have the advantages of sand, such as high permeability, easy drainage and consolidation, and high shear strength, nor does it have the advantages of clay, such as good waterproof performance, not easy to be eroded by water, and high cohesion. In many engineering problems, it exhibits poor mechanical properties.
[0003] Silt slopes are widely distributed in alluvial plains, river deltas, and plains along rivers and coasts in my country. The structural characteristics of silt slopes are that the connection between soil particles is very weak, and it is very sensitive to moisture content. When silt absorbs water and the moisture content changes slightly, it will quickly lose strength. When silt slopes are subjected to external forces, such as the impact of water flow and its own gravity, the soil's own resistance is low, and it is very easy to form gully erosion, landslides, collapses, sinkholes and other phenomena, which have a serious impact on the embankment and river ecological environment.
[0004] In order to avoid secondary geological disasters such as collapse, landslide, mud-rock flow and so on in silt slopes, slope hardening or building flood control dikes on the outside of silt slopes are usually adopted to ensure the stability of the slope. However, after such protection, the surface vegetation of silt slopes can hardly grow, which has a negative impact on the original ecological environment in the area.
[0005] For the greening of silt slopes, the method usually adopted is to sow grass seeds and plant seedlings. After the plants have grown, the silt slopes are reinforced by the soil-fixing effect of the plant roots. This method has a certain effect of soil conservation and erosion prevention, but because plant growth requires a certain amount of time and the silt slope itself has poor stability, the soil layer of the slope is easily lost with the erosion of rain or river water, forming gullies and sinkholes on the slope surface, causing deformation of the slope structure or even collapse. If the silt slope is directly hardened or an engineering protection is constructed on the outside of the slope, it is difficult to solve the problem of ecological protection.
[0006] Therefore, it is necessary to develop a high-strength compression-resistant and impact-resistant vegetation planting construction structure for silt slopes. Summary of the invention
[0007] The purpose of the utility model is to overcome the shortcomings of the above-mentioned background technology and to provide a high-strength compression and impact-resistant vegetation planting construction structure for a silt slope.
[0008] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a high-strength compression and impact-resistant vegetation planting construction structure for a silt slope, characterized in that: it includes an ecological vegetation mesh mat with one end located in the ground at the bottom of the slope and the other end laid along the silt slope and located in the ground at the top of the slope; the ecological vegetation mesh mat is fixed to the silt slope by U-shaped nails or anchor rods, and the ecological vegetation mesh mat includes, from bottom to top, a lower bidirectional geogrid, planting soil, an upper bidirectional geogrid and a degradable surface layer.
[0009] In the above technical solution, the ecological vegetation mat also includes a folded bidirectional geogrid located in the planting soil; the folded bidirectional geogrid is serrated, and the upper and lower ends of the folded bidirectional geogrid have multiple bends, the bend at the upper end passes through the upper bidirectional geogrid and is located in the degradable surface layer, and the bend at the lower end passes through the lower bidirectional geogrid and is located in the silt slope.
[0010] In the above technical solution, the bend at the upper end and the bend at the lower end of the folded bidirectional geogrid are connected by a fixed rope.
[0011] In the above technical solution, the fixing rope is wavy in shape.
[0012] In the above technical solution, a plurality of ecological vegetation mesh mats are overlapped on the silt slope along the water flow direction, and the ecological vegetation mesh mats close to the water flow direction are overlapped on the ecological vegetation mesh mats away from the water flow direction.
[0013] In the above technical solution, grass seeds or small and medium-sized shrubs are planted in the planting soil.
[0014] In the above technical solution, the ecological vegetation net mat includes a slope bottom section, a silt slope section and a slope top section; the slope bottom section includes a slope bottom ground section located on the slope bottom ground, a slope bottom inclined section extending into the slope bottom ground and an slope bottom landfill section located in the slope bottom ground; the slope top section includes a slope top ground section located on the slope top ground, a slope top inclined section extending into the slope top ground and an slope top landfill section located in the slope top ground.
[0015] In the above technical solution, the lengths of the ground section at the bottom of the slope and the ground section at the top of the slope are both greater than 1000mm; the angle between the ground at the bottom of the slope and the inclined section at the bottom of the slope, and the angle between the ground at the top of the slope and the inclined section at the top of the slope are both 45 degrees; the lengths of the landfill section at the bottom of the slope and the landfill section at the top of the slope are both 600mm, and the burial depths are both greater than 600mm.
[0016] In the above technical solution, the spacing between the lower bidirectional geogrid and the upper bidirectional geogrid is adjusted by the folded bidirectional geogrid, and the adjustment range is 2.0 cm-6.0 cm.
[0017] Compared with the prior art, the utility model has the following advantages:
[0018] 1) In order to improve the stability of the silt slope, the utility model lays an ecological vegetation mesh mat on the surface of the silt slope for protection, thereby improving the overall stability of the slope and achieving the effect of preventing scour; at the same time, in order to strengthen the integrity of the planting mesh mat and the silt slope, a reinforced soil method is used to improve the stability of the overall slope.
[0019] 2) The ecological vegetation mat of the utility model forms a "three-dimensional space" structure through the lower bidirectional geogrid and the upper bidirectional geogrid. The "three-dimensional space" structure forms a "three-dimensional space" sandwich by folding the bidirectional geogrid and fixing the rope. The height of the "three-dimensional space" sandwich can be adjusted by folding the bidirectional geogrid, and the adjustable height range is between 2.0cm-6.0cm; the "three-dimensional space" sandwich is backfilled with planting soil and grass seeds or small and medium-sized shrubs; the plant roots are entangled in the "three-dimensional space" structure to form an "erosion control system", so that all plant roots, geogrids, planting soil, and silty slopes form a whole, which not only strengthens the "grasping ability" of plant roots on the soil, but also the planting soil in the vegetation mat reduces the direct or distance contact between water and silty soil, thereby increasing the overall anti-scouring and anti-erosion capabilities of the silty soil slope, and providing a long-lasting and firm "anti-erosion system" for the silty soil slope with poor ecological restoration ability.
