Problems solved by technology

[0003] Vegetation is especially important in semi-arid areas, where wind erosion of the soil is very serious, and it is common for farmland to be buried by quicksand. Vegetation is the guardian of the soil, which can block and control the quicksand on the windward side and protect the windward farmland. At the same time, it can also significantly reduce the harm of dry and hot wind; but when the slope is consolidated, it is not only possible to rely on vegetation, but also to take certain support, reinforcement and protection measures for the slope. Ecological slope protection is a geotechnical and environmental engineering The product of the combination, it takes into account the effects of both protection and the environment, and is a very effective means of slope protection and slope consolidation; but the current traditional ecological slope consolidation system can only achieve the function of protection, and cannot improve the soil , especially in semi-arid areas, if the soil is not improved, it will be difficult for the transplanted vegetation to survive, which will cause the ecological slope reinforcement system to lose its environmental protection effect

Embodiment 1

[0042] Embodiment 1: as Figure 1 to Figure 5 As shown, the ecological slope reinforcement system in the semi-arid plain area includes:

[0043] A slope top support structure 1, the slope top support structure 1 includes a longitudinal earth retaining plate 1-1, the middle part of the longitudinal earth retaining plate 1-1 is provided with a water storage groove 1-2, and the water storage groove 1 -2 The bottom is provided with a drainage pipe 1-3 connected to the slope of the ecological slope;

[0044] A slope soil fixing structure 3, the slope soil fixing structure 3 includes a soil improvement foundation, an ecological bag 3-2 and a support frame 3-1; the soil improvement foundation is laid on the slope of the ecological slope, and the soil improvement foundation The upper surface is laid with stacked ecological bags 3-2, and the ecological bags 3-2 are filled with plant growth substrates; the upper end of the supporting frame 3-1 is detachably connected to the longitudina...

Embodiment 2

[0050] This embodiment is based on Embodiment 1, the slope top support structure 1 also includes a soil and water conservation foundation 4, and the soil and water conservation foundation 4 is located on the side of the water storage ditch 1-2 away from the longitudinal earth retaining plate 1-1 The retaining structure 2 at the bottom of the slope also includes a soil and water conservation foundation 4, which is located on one side of the retaining wall 2-1, and the soil and water conservation foundation 4 includes:

[0051] The plain soil layer 4-1, the plain soil layer 4-1 is laid on the top of the ecological slope or at the bottom of the ecological slope;

[0052] Water retention layer 4-2, the water retention layer 4-2 is laid on the upper surface of the plain soil layer 4-1 for retaining moisture;

[0053] The vegetation restoration layer 4-3, the vegetation restoration layer 4-3 is a native plant layer, and the roots of the seedlings of the native plants are planted in ...

Embodiment 3

[0056] The present embodiment is based on embodiment 1, and described soil improvement foundation 5 comprises:

[0057] A soil improvement layer 5-1, the soil improvement layer 5-1 is laid on the slope of the ecological slope;

[0058] An organic matter layer 5-2, the organic matter layer 5-2 is laid on the upper surface of the soil improvement layer 5-1;

[0059] Water retention layer 5-3, the water retention layer 5-3 is laid on the upper surface of the organic matter layer 5-2;

Abstract

The invention discloses a slope stabilization system for an ecological side slope in a semiarid plain terrain. The slope stabilization system comprises a slope roof supporting structure, a slope bottom blocking structure and a slope surface soil stabilization structure. The slope surface soil stabilization structure comprises a soil improvement foundation and a supporting frame, the soil improvement foundation is laid on an inclined plane of the ecological side slope, stacked ecological bags are laid on the upper surface of the soil improvement foundation, and the ecological bags are filled with plant growth matrixes. The upper end of the supporting frame is detachably connected with a longitudinal soil retaining plate, the lower end of the supporting frame is detachably connected with a retaining wall, and the supporting frame is used for compacting the ecological bags on the soil improvement foundation. The slope stabilization system for the ecological side slope in the semiarid plain terrain can improve the soil environment, has a high water retaining property, provides nutrients for plant growth, ensures rapid growth of plants, and plays a role in stabilizing the slope.

Description

technical field [0001] The invention relates to the technical field of environmental geotechnical engineering, in particular to an ecological slope reinforcement system in a semi-arid plain area. Background technique [0002] The semi-arid area refers to the climate type area with an average annual precipitation of 350-500 milliliters. The semi-arid area refers to the central and northern regions of Henan Province, the central and eastern regions of Inner Mongolia, and the West Sea in Hebei, Yanbei of Shanxi, northern Shaanxi, and southern Ningxia. Agricultural areas including Dingxi and Yuzhong in Gansu, Yushu and Guoluo in Qinghai, and Lhasa in Tibet; [0003] Vegetation is especially important in semi-arid areas, where wind erosion of the soil is very serious, and it is common for farmland to be buried by quicksand. Vegetation is the guardian of the soil, which can block and control the quicksand on the windward side and protect the windward farmland. At the same time, i...
