[0005] The purpose of the present invention is aimed at the defects and deficiencies in the prior art, and proposes a SNS flexible green protection net for rock slope management and its construction method. This SNS flexible green protection net is a combination of traditional The perfect combination of the SNS flexible protective net and the current guest soil wet spraying method not only makes the loose rock slope matrix on both sides of the mountainous road tightly bonded and is not easy to fall off, but also overcomes the traditional single slope protection or single slope greening to maximize the utilization of resources and save huge manpower and material resources

Embodiment
[0035]The specifications of the used sawtooth hot-dip galvanized high-strength steel sheet 4 in this embodiment refer to the current common spraying substrate thickness, and the sawtooth length of the sawtooth hot-dip galvanized high-strength steel sheet 4 is 20cm for use; After treating the pumice and floating soil on the slope, drilling the anchor hole 9 and laying the steel wire mesh, the serrated hot-dip galvanized high-strength steel sheet 4 is rotated to the position of engaging with the rocky slope by rotating the door leaf 11, and the steel sheet serrated 12 is embedded The rock mass is 10cm; after the installation of the new SNS flexible green protection net with sawtooth hot-dip galvanized high-strength steel sheet 4 is completed, the rock slope is sprayed with a liquid sprayer using traditional guest soil wet spraying.

The invention relates to an SNS flexible greening protective net for rock slope treatment and a construction method thereof. According to the SNS flexible greening protective net, a plurality of rotatable sawtooth hot galvanized high-strength steel sheets are mounted on steel wire net ropes of a traditional SNS flexible protective net at intervals in a staggered manner, and even SNS flexible greening protective net steel wire grids are formed in the transverse direction and the longitudinal direction. The SNS flexible greening protective net provided with the sawtooth hot galvanizing high-strength steel sheets is sewn to frame supporting steel wires by sewing ropes through anchor rod buckles, and the SNS flexible greening protective net is fixed to a rock slope needing to be protected, treated and greened through steel rope anchor rods. By means of the SNS flexible greening protective net, loose rock slope matrixes on the two sides of a mountain road are closely combined and are not prone to falling off, and the defects of traditional single slope protection or single slope greening are overcome so that maximum utilization of resources can be achieved; and great manpower and material resources are saved.
Description
technical field [0001] The invention relates to an SNS (Safety Netting System) flexible protection net, in particular to an SNS flexible greening protection net for rock slope treatment and a construction method thereof, belonging to the technical field of rock slope protection. Background technique [0002] With the continuous improvement of the road system, mountainous roads have also been greatly developed, and these areas are often high and dangerous, and rolling stones block traffic and endanger people's lives and safety. Accidents occur frequently, and the excavated slopes seriously damage the local ecological environment. , causing serious soil erosion and ecological damage. Therefore, the loose rock slopes on both sides of the mountain road must be protected and treated in time. [0003] Traditional protection measures for loose rock slopes on both sides of roads in mountainous areas include face protection walls, mortared rubble slope protection, hanging net sprayi...
