Novel hillside rainwater collection system and mountain torrent and debris flow control method

Abstract

The invention discloses a novel hillside rainwater collection system and a mountain torrent and debris flow control method and relates to the technical field of rainwater collection and utilization and geological disaster control technologies. The novel hillside rainwater collection system mainly comprises four major subsystems, namely a hillside rainwater converging subsystem, a water-stone separation subsystem, a power generation subsystem and an irrigation subsystem, wherein the hillside rainwater converging subsystem comprises a debris flow monitoring and early warning module, an ecological slope protection module and netted open channels; the water-stone separation subsystem comprises flexible drainage guide grooves, silt accumulation pools and a sub-hill tunnel; the power generation system comprises a power generation workshop, a barrier dam and a reservoir; the irrigation subsystem comprises open channels and a drip irrigation subsystem. The novel hillside rainwater collection system and the mountain torrent and debris flow control method have the advantages of being simple in design, convenient to construct, low in project cost and general in applicability.

Description

technical field [0001] The invention relates to the technical field of rainwater collection and utilization and prevention and control of geological disasters, in particular to a novel hillside rainwater collection system and a method for preventing and controlling mountain torrents and debris flows. Background technique [0002] Debris flow is a phenomenon in which the mixture of loose soil and water flows along the slope under the action of gravity. It mostly occurs in mountainous areas, and its area, volume and flow are relatively large. A typical mudslide consists of a viscous slurry rich in silt and clay in suspension of coarse solid debris. Under appropriate terrain conditions, a large amount of water soaks the solid accumulations in the flowing water hillside or ditch bed, reducing its stability, and the solid accumulations saturated with water move under their own gravity, forming a debris flow. Due to the sudden and ferocious eruption of mudslides, it is difficult ...

Problems solved by technology

[0005] In actual projects, most of the debris flow prevention and control measures include setting up retaining dams in stages to block and stop debris flows; setting up drainage projects such as drainage ditches to dredge mountain torrents, debris flows, and landslides, etc. These prevention and control measures have limitations. Like the blocking and silting project, its treatment can achieve certain results in the early stage, but its project cost is high, the construction requirements are high, and the maintenance cost is high in the later stage, so it cannot achieve sustainable development
