A method of repairing rock slopes by spraying

Abstract

The invention provides a method for repairing a rocky inverted slope by spraying, which comprises the following steps: constructing an intercepting ditch at the top of the slope; cleaning up dangerous rocks; laying a protective net and fixing it on the slope surface through bolts; spraying matrix layer a; laying water absorbing The blanket is fixed by iron wires, protective nets and anchors; the matrix layer b is sprayed; the protective net is laid and fixed on the slope by anchors; the matrix layer c is sprayed; the seed layer is sprayed. The present invention adopts the process of spraying four times of double-layer hanging nets to realize the ecological restoration of the inverted slope surface, and the four-time spraying of double-layer hanging nets is formed to avoid the phenomenon that the substrate is too thick in a single spraying sowing and the substrate falls off; in addition, the water interception The water in the ditch flows into the substrate layer along the nylon fiber of the absorbent blanket, and is absorbed by the vegetation on the slope, which solves the problem that the slope cannot receive natural rainfall and is difficult to maintain by artificial watering; the configured substrate is light in weight, and the substrate layer is bonded to the slope High stability, the substrate is not easy to fall off, high stability and safety, and good water retention performance, which can achieve lasting safety and regreening effect on the slope.

Description

technical field [0001] The invention relates to the technical field of slope restoration, in particular to a spray seeding repair method for rocky inverted slopes. Background technique [0002] Because the slope of the inverted slope is greater than 90 degrees, it cannot receive natural rainfall, and artificial watering cannot store water, and it does not have the necessary water conditions for plant growth. At present, planting climbing plants at the bottom of the slope or hanging plants at the top of the slope are mainly used for inverted slopes. However, these two planting methods not only grow slowly and cannot change seasons, but are also relatively fragile. Easy to break under conditions. Secondly, most inverted slopes do not carry out vegetation establishment, but adopt the method of only cutting the slope to make it into a positive slope. This method is simple and fast, but in general, the amount of work is relatively large, and it is easily restricted by space. ...

Problems solved by technology

This method is more difficult to construct, and the stability of the additional building materials is poor. The filling material is heavy and the load is heavy, causing secondary damage.

There is also the method of spraying ceramsite vermiculite concrete to correct the inverted slope surface into a positive slope body. Although the weight of the filling material is reduced and the stability of the building material is improved, the material cost of ceramsite vermiculite concrete is high, and the repair cost is high. , it is difficult to promote the application on a large scale
