Method for consolidating soil, protecting slope and planting vegetation on rock slope

Abstract

The method for creating vegetation on rock slope land by waste and old tyres includes the following steps: finishing slope surface, laying waste and old tyres on the slope surface and fixing them, according to the requirements of plant growth preparing nutrients oil and planting soil or seived natural soil, filling the soil into the tyre bead, sowing suffurticosa plant and others, uniformly spraying fertilizer, stabilizing agent and covering material on the slope soil and covering with sun shading net.

Description

technical field [0001] The invention is applied to the technical field of rock slope greening. technical background [0002] At present, the greening effect of rocky slopes, especially cutting slopes, is not ideal, with low vegetation coverage and poor soil and water conservation effects. The main reason is that the rock hardness of the road slope is high, and the lack of soil and water affects the growth of plant colonization. On the one hand, the combination of high temperature in summer, drought and cold wave in winter greatly reduces the green period of vegetation. On the other hand, strongly weathered rocky slopes and granite slopes have steep slopes, irregular slope repairs, uneven surfaces, and lack of soil for plants to survive. Usually, even after spraying in these places, either the seeds are difficult to germinate and grow, or due to improper management measures, they will be sun-dried or dried out soon after germination, so that the expected greening effect can...

Problems solved by technology

At present, hollow bricks, "free beams" and three-dimensional nets are mostly used for soil consolidation on highway slopes. In addition to the need for very smooth slopes, the former two require a lot of labor and cement, sand and other building materials to make hollow bricks and "free beams". "skeleton

Three-dimensional mesh has a better effect of fixing soil and planting grass on slopes with flat surfaces, but it is limited to applications on soil and strongly weathered rock slopes

Planting vines is a simple and economical way of greening slopes, but it takes a long time to achieve the expected greening effect, and it is impossible to achieve year-round greening

Spraying cement and stone protection are the common ways to quickly stabilize slopes at present, but the cost is high, and the slope after spraying or protection is lack of vitality, which is easy to cause a feeling of depression to the passing passengers

Foreign soil spraying is an ideal method for greening rock slopes, but its technical content is quite high. It is still in the experimental and exploration stage in China at present. The process is complicated, the requirements for foreign soil materials are high, and the cost is also high.

In contrast, geocells have the advantages of simple operation and good land effect, which brings a new hope to rock slope greening, but the price of geocell itself is relatively expensive, and it is not easy to be popularized and applied in large quantities.
