Loess slope composite biological protection system

Abstract

The invention relates to a loess slope composite biological protection system. The loess slope composite biological protection system comprises a slope platform and an inclined slope; a water storage well and a transverse diversion canal are built on the slope platform; vertical diversion canals are arranged on the two side edges of the inclined slope; buffer plates are arranged in the transverse diversion canal and the vertical diversion canals; hydraulic power generation devices are arranged in the vertical diversion canals and arranged between the buffer plates; solar street lamps externally connected with the hydraulic power generation devices are arranged on the slope platform; concrete grid rib beams are laid on the inclined face of the inclined slope and fixed through anchor rods; ecological planting bags are laid in grids of the concrete grid rib beams. Irrigation water pipes are arranged on the inclined slope and connected with the water storage well through buried pipelines; and sand wells are arranged at the bottoms of the vertical diversion canals at intervals. The loess slope composite biological protection system is reasonable and effective, and the effective protection system integrates slope protection, water and soil loss protection and environment protection and greening.

Description

technical field [0001] The invention belongs to the technical field of slope protection, and in particular relates to a compound biological protection system for loess slopes. Background technique [0002] Slope protection has been widely used in many engineering fields such as civil engineering and construction, and ecological restoration of slopes in the later stage of open-pit mines. However, the ecological damage caused by large-scale excavation of earthwork will cause environmental damage to regions and cities for a long time. Existing for a long time, especially in northern Shaanxi and even Northwest China, the loess has a small cohesive force and is very easy to generate dust, which is the main cause of sandstorms and soil erosion. Landslides and soil erosion occurred. [0003] The traditional slope protection system often uses mortar rubble and anchor spray slope protection. Although it can prevent further weathering of the slope to a certain extent, the gray and mo...

[0002] Slope protection has been widely used in many engineering fields such as civil engineering and construction, and ecological restoration of slopes in the later stage of open-pit mines. However, the ecological damage caused by large-scale excavation of earthwork will cause environmental damage to regions and cities for a long time. Existing for a long time, especially in northern Shaanxi and even Northwest China, the loess has a small cohesive force and is very easy to generate dust, which is the main cause of sandstorms and soil erosion. landslides and soil erosion

[0003] The traditional slope protection system often uses mortar rubble and anchor spray slope protection. Although it can prevent further weathering of the slope to a certain extent, the gray and monotonous engineering structure destroys the effect of plant protection on beautifying the slope environment and regulating slope humidity. temperature, which plays a role in consolidating and stabilizing the slope; in my country, plant protection mainly relies on laying turf for the initial protection of the slope. protection; therefore, a single slope protection measure cannot effectively solve the problem of loess slopes, and it is necessary to take a reasonable and effective control method; a compound biological protection system for loess slopes provided by the invention will plant The optimized combination of measures and engineering measures can effectively solve the contradiction between slope engineering protection and ecological environment damage, effectively protect slope soil damage, prevent and control soil erosion, control covered loess dust, and effectively increase vegetation coverage
