High and steep rock slope greening protection and construction method

Abstract

The invention relates to high and steep rock slope greening protection. The high and steep rock slope greening protection includes a slope rock mass; a plurality of anchor rod drill holes are formed in the slope rock mass, anchor rods are arranged in the anchor rod drill holes, slope protection facilities are arranged on the anchor rods, and the slope protection facilities are arranged in an overhead mode; a plurality of rivets are further arranged on the slope rock mass, baffles are connected to the rivets, and the bottoms of the baffles abut against the slope surface of the slope rock mass;the slope rock mass, the slope protection facilities and the baffles are provided with greening facilities; compared with the prior art, the anchor rods, a flexible protective net and a thick-layer base material greening technology are combined, and the anchor rods can play a role of strengthening a slope body to improve the slope stability; the flexible protective net is used for preventing the bare slope surface or slope surface protected by spraying concrete from causing the phenomenon that the slope surface is broken and loosened or blocked, and plays a protective role on the slope surface, and at the same time provides a platform for thick-layer base materials to enhance the adhesiveness of a matrix; and the thick-layer base material greening technology makes full use of planting holes, the baffles, planting bags, a metal net and the SNS flexible protective net for the slope surface greening.

Description

technical field [0001] The invention belongs to the technical field of ecological protection for high and steep rocky slopes, and in particular relates to a green protection and construction method for high and steep rocky slopes. Background technique [0002] At present, in the construction of roads, railways, mines, water conservancy and other projects, a large amount of earthwork excavation is often required, which destroys the original vegetation and forms a large number of steep rock slopes. The slope protection methods include anchor spraying, anchor rods, active flexible protective nets, anchor rod frames, protective walls, retaining walls, etc., which are combined with measures such as climbing vines, thick-layer substrates, and high-order aggregates to protect the slope surface. Greening treatment can play a certain role in greening slope protection, but it is still difficult to meet the current high requirements for green roads and ecological slope protection. It ...

Problems solved by technology

However, this method is only suitable for slopes whose slopes are gentler than 1:0.5 and above, and does not involve greening protection for rocky slopes with steep slopes.

On the other hand, this method uses shotcrete to reinforce the slope, which is likely to cause environmental pollution. At the same time, cavities are easily formed between the concrete and the slope rock mass over time, and it is easy to fall off in the later stage, which will bring certain problems to the driving. security risks

[0006] The Chinese patent with the publication number CN101696574 A proposes a SNS flexible green protection net and its construction method for rock slope treatment. Disadvantages of single protection and single greening of soil spraying method to achieve maximum utilization of resources

However, for rock faces with steep slopes and smooth surfaces, the spraying technology of guest soil application method is prone to matrix shedding, poor greening effect, and difficult vegetation growth; while the active flexible protective net mainly prevents the surface of the slope from falling off and falling off. The overall and local stability of the slope is poorly reinforced
