Water and soil co-storage and ecological slope protection method for karst sloping field and stony desertification side slope

Abstract

The invention discloses a water and soil co-storage and ecological slope protection method for a karst sloping field and a stony desertification side slope. The water and soil co-storage and ecological slope protection method comprises the following steps that small anchor rods are arranged on the slope surfaces of the karst sloping field and the stony desertification side slope line by line, a soil retaining plate is placed in front of the small anchor rods to form plate grooves, and cofferdams or baffles are arranged at two ends of the plate grooves; a rainwater collecting surface material is arranged on the slope surface between the plate grooves to collect rainwater; an anti-seepage cushion layer is laid in each stage of plate groove, a grating plate on which a plurality of water absorption belts are fixed in advance is arranged at a certain height in a plate groove, the grating plate leans against the soil retaining plate and the slope surface so as to be kept stable, planting soil is filled on the grating plate to form a planting layer, and a water storage cavity space below the grating plate serves as a water storage layer; plants with long roots and developed main root systems are planted in a planting soil layer, and plants with short root systems are supplemented. According to the water and soil co-storage and ecological slope protection method for the karst sloping field and the stony desertification side slope, slope rainwater collection and rainwater accumulation of the karst sloping field and the stony desertification side slope are integrated, water and soil co-storage and water and soil conservation of the karst sloping field and the stony desertification side slope, ecological slope protection treatment and ecological environment reconstruction are achieved, meanwhile, the treatment cost is saved, and the treatment method is simplified.

Description

technical field [0001] The invention belongs to the fields of ecological slope protection management and ecological environment reconstruction of karst slopes and rocky desertification slopes, and specifically relates to a method and a device for water and soil co-accumulation and ecological slope protection of karst slopes and rocky desertification slopes. Background technique [0002] At present, in the humid areas of southern my country, the long-term karst of carbonate rocks and large areas of bedrock or stone piles are exposed on the surface, and the surface loss and underground loss of slope water and soil are serious, resulting in rocky desertification and ecological environment degradation. Soil loss in karst slope land can be divided into two ways: surface loss and underground loss. For pure carbonate rock slopes with well-developed karst gullies, troughs and depressions and serious petrification, underground leakage is the main soil loss mode. Karst slopes and roc...

Problems solved by technology

In the construction of the accumulation rain section, the karst fissure channel will continue to develop with the time of water action, because the distribution law of the karst channel cannot be found, and the grouting plugging is also difficult to work
