A method for protecting the slope of Pisha sandstone modified blocks

Abstract

The invention discloses a method for protecting an arsenic sand rock side slope by adopting arsenic sand rock modified building blocks. The method comprises the following steps: 1, dividing slope surfaces into steep slopes and gentle slopes according to slope gradient of a side slope; 2, roughly flattening the slope surfaces with different slope gradients and building the arsenic sand rock modified building blocks on the flattened slope surfaces in a grouping manner; 3, planting herbal plants or woody plants in plant-growing holes of the arsenic sand rock modified building blocks which are built in a grouping manner in the step 2, planting grass in building block plant-growing holes of the steep slope section, and planting the grass or trees on the steep slope. According to the method disclosed by the invention, the arsenic sand rock side slope is protected by using the arsenic sand rock modified building blocks, so that in-place resource utilization of the arsenic sand rock is realized, and the problem that an existing side slope protection way needs to be continuously and renewedly protected every year is also solved; moreover, by adopting the method, the characteristic of the arsenic sand rock is comprehensively utilized, materials are taken in place, and protection of the side slope by using green planting and preparation of the modified building blocks are combined effectively, so that a protection effect is enhanced.

Description

technical field [0001] In view of this, the present invention belongs to the field of soil and water conservation or ecological restoration, and in particular relates to a method for protecting the slope of arsenic sandstone by modified blocks of arsenic sandstone. Background technique [0002] Soil erosion and Yellow River siltation have been serious problems in the middle and lower reaches of the Yellow River in my country for nearly a hundred years. The reason is that the ecological degradation and serious soil erosion in the Loess Plateau. Soil erosion and ecological degradation promote each other, forming a vicious circle. A large amount of sediment produced by ecological degradation and soil erosion flowed into the Yellow River, causing the riverbed of the Yellow River to rise rapidly, forming a suspended river above the ground, seriously threatening the lives and property safety of people along the middle and lower reaches of the Yellow River, and restricting the econ...

Problems solved by technology

However, there are many problems in these existing measures. The erosion of the arsenic sandstone is caused by many aspects. When the slope is treated with biological measures, the stability of the natural arsenic sandstone slope will be destroyed, and the soil erosion of the slope will be further aggravated. ; When the sandstone slope is protected by spraying consolidation materials or cement mortar, it is difficult for these materials to penetrate into the deep inside of the sandstone, and only a thin consolidation layer is formed on the surface of the sandstone. The local freeze-thaw erosion is particularly Seriously, after the sandstone under the consolidation layer is damaged by freeze-thaw erosion, the consolidation layer will slide down the slope as a whole, and it is necessary to spray consolidation materials or cement mortar every year to re-protect the sandstone slope
