Description

Anchor rod-ecological rod combined structure system for ecological restoration of steep rock slope

The technical field is as follows:

the invention belongs to the technical field of ecological restoration equipment and slope protection engineering, and particularly relates to an anchor rod-ecological rod combined structure system for ecological restoration of a steep rock slope.

Background art:

at present, the slope engineering is mainly applied to disaster protection and engineering construction. In the aspect of disaster protection, landslide is a geological disaster mainly faced by people at present; in the aspect of engineering construction, a large amount of basic engineering construction can all relate to the side slope problem. Therefore, the reasonable management of the side slope is very important. For the steep rock slope, the safety and ecological problems of the slope are particularly prominent due to the large sliding force and the poor surface plant growth conditions. If the slope is not treated or is not treated properly, the slope not only faces ecological problems such as water and soil loss, but also induces serious landslide disasters.

In slope protection engineering, the stability and the ecological property of a slope behind the slope protection cannot be considered by the existing slope protection technology. For example, although the use of pure mechanical structural systems such as anchor cable frame beams can ensure the safety and stability of the side slope, the ecological restoration capability is often limited, and the use of ecological structural systems such as ecological perforated bricks for revetment and the like can ensure the ecological function of the side slope to a certain extent but is not suitable for the treatment of the side slope with a large slope.

With the continuous improvement of the production technology level of the construction industry in China, people do not limit the treatment of steep rock slopes to the most basic requirements on safety and stability any more, and the requirements on the landscapes and the ecology of slopes behind the revetments are increasingly strong. Obviously, the slope protection structure system considering single index is difficult to realize win-win of ecological property and safety of the slope after treatment.

The invention content is as follows:

the invention aims to provide an anchor rod-ecological rod combined structure system for ecological restoration of a steep rock slope, which can effectively restore the slope ecology while ensuring the safety of the steep rock slope.

In order to achieve the aim, the invention provides an anchor rod-ecological rod combined structure system for ecological restoration of a steep rock slope, which comprises an ecological rod combined structure and a slope anchor rod binding structure, wherein the ecological rod combined structure and the slope anchor rod binding structure are arranged along a slope surface. The ecological rod combined structure comprises an ecological rod and a flexible non-degradable rubber plate adaptive to a slope surface, and the ecological rod is transversely fixed on the flexible non-degradable rubber plate through a special anchor; the slope anchor rod structure comprises an anchor rod and a steel cable, and the ecological rod combined structure is bound on the slope surface of the steep rock slope through the anchor rod and the steel cable.

Preferably, the anchor rod-ecological rod combined structure system can still ensure the stability of the combined system under the condition of local instability of a slope surface.

Preferably, gaps are reserved between the transverse ecological rods and the rows parallel to the slope surface, and the transverse ecological rods can be used for further slope treatment.

Preferably, the structural system is suitable for ecological restoration of steep rock slopes with slopes greater than 50 degrees.

Preferably, one end of the wire rope is connected to the anchor rod.

Preferably, a hanging ring is arranged at the edge of one side of the flexible non-degradable rubber plate adapting to the slope surface, and the other end of the steel cable is connected to the hanging ring.

Preferably, the flexible non-degradable rubber plate adapted to the slope surface is designed to be a porous structure for saving materials, and is permeable to water and air, and small holes for the special anchors to pass through are formed in the central symmetry position.

Preferably, the special anchor passes through the small hole of the porous flexible non-degradable rubber plate adapted to the slope from bottom to top and then passes through the ecological rod to complete anchoring.

Preferably, the porous flexible non-degradable rubber plates for fixing the adaptive slope surface of the ecological rod are arranged at intervals.

Based on the above structural system, the invention has the advantages that: the anchor rod-ecological rod combined structure system for ecological restoration of the steep rock slope is characterized in that an ecological rod is anchored on a flexible non-degradable rubber plate adaptive to the slope surface through a special anchor, and under the premise that the slope stability is ensured through anchor rod anchoring, the ecological rod combined structure is bound on the slope surface of the steep rock slope through a steel cable connecting the anchor rod and the flexible non-degradable rubber plate, so that a stable mechanical structure system is finally formed, the problems of safety and stability and ecological restoration of the steep rock slope are solved, and mechanical support is provided for further management of the slope.
