Soil-reinforcement component used for ecological restoration of steep rock slopes

Abstract

The invention relates to a soil-reinforcement component used for ecological restoration of steep rock slopes. The soil-reinforcement component comprises an irrigation system, soil-reinforcement bricksand a cover plate that are arranged from bottom to top along a slope, wherein first and second grooves of two adjacent soil-reinforcement bricks correspond to each other to form first cavities and second cavities that are fixed on the slope through anchoring assemblies; in the irrigation system, water collection troughs are arranged on the flat bottom on the top of the slope or the flat bottom onthe bottom of the slope, a water pipe is arranged in the first cavities, and a water pump provides power to perform underground infiltration irrigation for the slope vegetation; planting holes are distributed in the surface of the cover plate, and pins are arranged perpendicular to the surface of the cover plate and correspondingly inserted into second through holes to fix the cover plate above the slope. The invention seals a certain amount of soil on the surface of the rock slope through the soil-reinforcement bricks. The first cavities on the soil-reinforcement bricks are combined with theirrigation system, and the second cavities are combined with the cover plate, which realizes the expansion of soil space on the surface of the rock slope, and can accommodate the growth of more kindsof plants. The invention has the advantages of a flexible structure and strong adaptability.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a soil-fixing component used for ecological restoration of steep rock slopes. Background technique [0002] Slope is the most common engineering form in engineering construction, and slope instability is one of the challenging tasks in the process of engineering construction. With the vigorous development of my country's infrastructure construction in recent years, mining, water conservancy, transportation A large number of slope problems are involved in engineering aspects, so it is of great significance to ensure the stability of the slope and study its treatment countermeasures in depth. This kind of slope is steep and has no vegetation conditions. It has the characteristics of large catchment area, low water storage and strong scouring force. Instability and sliding are the main problems hindering the normal operation of the project. It is difficult to restore t...

Problems solved by technology

For example, the addition of water-retaining agent makes the vegetation concrete also have a strong water-locking property. In addition, the cement solidifies to produce a loose and porous structure. Rainwater or overflowing groundwater is accumulated in the vegetation concrete, which increases the overall weight of the vegetation concrete. Vegetated concrete is prone to collapse

Secondly, the thickness of the vegetation concrete in the prior art is mostly 8-10cm, and the hanging net anchored on the slope is bonded to the slope. It is easy to deform, the thickness of the soil layer occupied by the vegetation is thin, the development of the root system is restricted, and the bottom directly contacts the rock, so there is no good foundation for long-term development
