Comprehensive slope treatment technique suitable for soft sandstone areas

Abstract

The invention relates to the technical field of ecological treatment and discloses a comprehensive slope treatment technique suitable for soft sandstone areas, comprising biological treatment, material treatment and engineering treatment. The comprehensive slope treatment technique provides treatment for soft sandstone small-watershed slopes from the multi-coupling aspect of biological measures, material measures and engineering measures, wherein the biological measures mainly involve planting in the different allocation modes of Hippophae rhamnoides, Thymus mongolicus, Agropyron cristatum andthe like; the material measures mainly involve anticorrosion growth accelerating materials and chemical grouting materials; the engineering measures mainly involve triangular weirs, interception ditches, interception basins, fish-scale pits, anchors and the like; the three measures are comprehensively allocated in the treatment of soft sandstone rock slopes so that soft sandstone fixation, vegetation growth promotion, and slope water-soil loss reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of ecological management, in particular to a comprehensive management technology applicable to slopes in arsenic sandstone areas. Background technique [0002] Ecological restoration refers to stopping human disturbance to the ecosystem to reduce load pressure, relying on the self-regulation and self-organization capabilities of the ecosystem to make it evolve in an orderly direction, or using the self-recovery ability of the ecosystem, supplemented by Artificial measures to gradually restore the damaged ecosystem or make the ecosystem develop in a virtuous cycle; mainly refers to the restoration and reconstruction of the natural ecosystems that have been damaged by natural mutations and human activities. [0003] Pisha sandstone is a kind of loose rock formation, specifically referring to the interbedded rocks composed of thick sandstone, sand shale and argillaceous sandstone in the Paleozoic Permian and Me...

Problems solved by technology

[0007] Due to the exposed surface of most of the existing Pisha sandstone, coupled with the interaction of water erosion, wind erosion and gravity erosion, the local extremely serious soil erosion has been caused, and it has become the main source of coarse sand in the middle reaches of the Yellow River. After entering the water flow and wind, the Pisha sandstone becomes Dust flows into the Yellow River following the water flow and separation, resulting in the accumulation of sand and soil in the Yellow River. Due to the loss of arsenic sandstone, ditches appear on the surface, and a large area of ​​water and soil is lost, causing serious ecological damage.
