Abstract:

In the process of slope excavation, the instability problem is prone to occur, which will bring some damage to the project. A new slope protection technology of  foreign-soil spray-seeding technology with double-layer protecting mesh is introduced. The anchoring high strength wire mesh is wrapped with PVC firstly, then the mixed foreign -soil is sprayed on slope surface by compressed air gun, and the seeds are sprayed on carrying soil at last. Through the combination of the vegetation and the wire mesh body, the purpose of the slope protection can be reached. Engineering practices indicate that this new technique can be applied in embankment where the slope is relatively stable and erosion is slight, and the effect is remarkable in preventing soil erosion and landscaping. 
