Problems solved by technology

Although this invention can create good growth conditions for plants, it has the following disadvantages: the one, it needs to hang the net before spraying, which is troublesome in construction and high in cost; Thick materials increase the load on the slope, which is not conducive to slope stability; third, the prepared spraying materials focus on improving soil fertility, and lack effective ingredients for regulating soil moisture and aggregate structure; fourth, mixing seeds and spraying materials The post-construction method is unscientific, and it is difficult for seeds buried deep in the soil to germinate; fifth, after the spraying material is constructed, it is covered with non-woven fabrics or straw curtains, and its anti-scouring effect and moisturizing effect are low, and it lacks an efficient protective layer

Abstract

The invention provides a plant net slope protection method, which comprises the following operation steps: 1) handling the slop surface; 2) installing an anchor rod; 3) preparing a slope protection substrate; 4) spraying the slope protection substrate on the slop surface; 5) paving, hanging and fixing a plant net; and 6) carrying out watering and late stage management. The method effectively enhances the stability of the geotechnical slope, reduces the engineering cost, and provides sufficient moisture and nutrient conditions for plant sprouting, so the density of plant seeds is reasonably controlled, and the invention ensures that the plant cover recovery of the geotechnical slope surface has good effect. The invention is mainly used for the slope plant cover protection.

Description

technical field [0001] The invention relates to a slope vegetation protection method, in particular to a slope protection method with planting nets. Background technique [0002] Slope is the most common geological form in engineering construction. Due to the lack of basic material conditions required for plant growth, the vegetation slope protection usually needs to be covered with thick artificial soil to meet the water and nutrient requirements of plants. At present, the common slope protection technologies mainly include guest soil spraying technology, spray-mixed planting technology, TBS vegetation slope protection technology, etc., but these technologies generally have thick covering soil (generally above 10cm), high cost, and large substrate load on the slope surface. Poor stability, low water effect, and high level of maintenance and management in the later stage have not yet been widely used. In addition, considering the water retention effect of the cover, a serie...
