Slope protective net with composite multilayer structure

Abstract

The invention discloses a slope protective net with a composite multilayer structure, and belongs to the field of protective nets. The slope protective net with the composite multilayer structure provided by the invention comprises a degradation layer I, wherein the surface of the degradation layer is sequentially covered by a soil layer, a degradation layer II, a left oblique layer, a right oblique layer and a circular net layer; the degradation layer I is 3.5 cm in thickness; the soil layer is 12 cm in thickness; the degradation layer II is 2 cm in thickness; the left oblique layer, the right oblique layer and the circular net layer are 0.5 cm in thickness. The slope protective net with the composite multilayer structure provided by the invention has the following characteristics: influence on the surrounding mountain environment is avoided; the protective net is settleable; the structure is diversified, and vegetation is guaranteed to fully grow while soil and stones are effectively prevented from dropping, so that the phenomena of landslide and water and soil loss are radically prevented.

Description

technical field [0001] The invention relates to a side slope protection net, in particular to a side slope protection net with a composite multi-layer structure. Background technique [0002] Human mining of ore, coal, oil, water, building materials and other resources, as well as construction behaviors such as excavation and landfilling of rock and soil during the construction of railways, highways, water conservancy, mines, tunnels, buildings, etc. A large number of exposed steep rocky slopes have caused a serious imbalance in the original environment and ecosystem. Moreover, these human activities often lead to certain geological disasters, such as land subsidence, landslides, collapses, and soil erosion. Therefore, the use of slope protection nets can effectively avoid the occurrence of landslides, collapses and soil erosion.

Problems solved by technology

[0003] However, the slope protective nets in the prior art are usually woven with flexible steel wire ropes, which are exposed to the air for a long time. After being exposed to wind, sun, and rain, the steel wire ropes will be corroded and broken, and the settlement of metal objects will affect the soil environment of the mountain. It has a huge impact, and it is difficult for the mountain soil itself to grow vegetation. This method will cure the root cause and not the symptoms; if the protective net is simply made of settleable materials, if the gap between the weaving net is large, it can prevent large pieces of soil and rocks from falling. Smaller pieces of soil and rocks cannot be prevented from falling. If the gap between the netting is small, it can effectively prevent the falling of soil and rocks, but it cannot guarantee that the vegetation has sufficient space to grow.
