Description

A hanging green board and rock slope ecological slope protection system

technical field

The invention relates to the technical field of slope support and greening, in particular to an anchored greening board and a rocky slope ecological slope protection system.

Background technique

In the process of construction of my country's transportation, water conservancy, electric power, mining and other engineering projects, it is not uncommon to see exposed slopes left over. These exposed slopes not only cause damage to the ecological environment and landscape, but also have various geological problems due to different material structures. Disaster hazard. Among them, the rocky slope poses a greater threat to the protection of the ecological geological environment. Under the long-term influence of rainfall and weathering, the exposed slope surface is often cut by cracks and becomes loose and broken, and the phenomenon of local collapse and fragmentation sometimes occurs. occurrence, and the ecological self-healing ability of the slope is extremely poor, and it cannot be self-greened, which seriously damages the natural landscape. Therefore, it is urgent to carry out the work of ecological slope protection for rocky slopes.

At present, there are many methods of ecological slope protection at home and abroad, although each has its own strengths, there are still places to be improved. For example, the concrete lattice beam slope protection method, although the green slope protection effect is better, but its construction complexity and expensive characteristics cannot be ignored; in the spray-mixed vegetation slope protection method, the combination of anchor rods and protective nets can effectively support the slope. Moreover, the setting of the vegetation layer can meet the greening effect, but it does not have the ability to control water and drainage under heavy rain conditions. When the vegetation layer is saturated and drains to the inner side of the slope, the cracks on the rock slope will be eroded by the water flow and continue to grow. When the rainfall is insufficient, this method cannot supply water for the vegetation by itself, so that the survival rate of the green vegetation is not high; although the fish scale pit excavation method can intercept surface runoff, store water and preserve moisture, it has a greater degree of damage to the original slope , the open pit is a permanent damage. Therefore, the problems existing in the ecological slope protection of rocky slopes have yet to be resolved.

When the bottom board 1 is obliquely attached to the slope, the bottom board 1 and the soil-carrying board 2 can jointly carry the covering soil, and the soil-carrying board 2 The overburden is divided into two sections for load bearing. On the one hand, it can bear part of the gravity of the overburden in sections, so that the overburden of each section will not cause the soil to be too dense due to excessive weight, thereby providing a loose environment for the growth and development of vegetation and effectively improving The growth and survival rate of vegetation in the covering soil is high. On the other hand, the soil-carrying plate 2 can prevent the covering soil from being washed away by the water flow to form soil erosion, thereby avoiding the loss of vegetation seeds in the covering soil; Sexual oblique creep, ensuring the stability of the covering soil. Drainage grooves 11 are arranged on the bottom plate 1, which can effectively discharge excess water; there are also a plurality of nutrient grooves 12 for filling solid blocks of plant fertilizers for providing nutrients to vegetation.

There are various shapes of the nourishment tank 12 , which are not limited here. For example, the nourishment tank 12 can be in the shape of a truncated cone with an upper diameter greater than that of the lower end, and is distributed on the bottom plate 1 in an array. The bottom of the nutrient tank 12 is hollowed out. When the plant root system passes through the bottom of the nutrient tank 12, the root system will grow around the hollowed-out top, and the root system is firmly locked, which greatly improves the relationship between the vegetation and the hanging green board 10. The tightness of the combination can provide space for air convection and aerobic respiration for the growth of plant roots, which is conducive to the growth and long-term survival of vegetation. The plant fertilizer solid block can be composed of α-naphthalene acetate, gibberellin, and sodium nitrophenolate.

It may also include a plurality of load-bearing beams 3 , and the load-bearing beams 3 are vertically arranged on the back of the soil-carrying board 2 for supporting the soil-carrying board 2 .

The vegetation concrete layer 4 can be formed by mixing soil, fine sand, cement, organic matter and amino acid fertilizer with water, and the upper surface of the vegetation concrete layer 4 is also sprayed with a water-retaining agent. Vegetation concrete containing water-retaining agent provides water storage space for green vegetation. When the rainfall is sufficient, the water-retaining agent can absorb and store the rainwater that infiltrates along the root system of the vegetation. When the rainwater is insufficient, the root system of the vegetation can absorb and store in the water-retaining agent by itself. There is no need to labor or set up another sprinkler to replenish water for the planting soil, so as to enhance the self-maintenance ability of the vegetation, improve the survival rate of the vegetation, and reduce the cost of vegetation maintenance.

The planting soil layer 6 includes soil, mulch and sand; the mass ratio of the soil, mulch and sand is 5:3-2:2-1.
