Side slope ecological restoration method based on coal gangue hydrophobic slope protection bricks

Abstract

The invention discloses a side slope ecological restoration method based on coal gangue hydrophobic slope protection bricks, and belongs to the field of environment-friendly building materials. Reinforcement treatment is conducted, specifically, concrete lattices are arranged on the slope edge, and pre-stressed anchor cables are stabilized in the lattices; slope protection bricks are laid, specifically, the slope protection bricks with the hollowed-out middles are laid on the side slope; the slope protection brick is prepared from the following raw materials in percentage by mass: 40-70% of coal gangue, 12-42% of natural sand, 5.14% of fly ash and 12.86% of cement. Hydrophobic treatment is conducted, specifically, waterproof paint is sprayed to the paved slope protection bricks; plants are planted, wherein vegetation is planted in the hollowed-out structures of the slope protection bricks; when the coal gangue slope protection brick is used for building a slope surface, water flows down along the drainage channel and cannot stay on the surface of a slope body, and seepage of the water and scouring of rainwater to the surface of the slope body are reduced; the contact angle between the surface of the slope protection brick sprayed with the waterproof material and water is enlarged, a hydrophobic state is formed, and water insulation and drainage of the slope are guaranteed.

Description

technical field [0001] The invention relates to the field of environmental protection buildings, in particular to a slope ecological restoration method based on coal gangue hydrophobic slope protection bricks. Background technique [0002] The rapid economic development has led to a surge in human demand for mineral resources. Long-term disorderly mining has caused deformation and damage to the rock mass of the mountain slope, disturbed topography and landform, and poor slope stability, which has led to a series of problems such as soil erosion and landslides. natural disaster. At present, under the policy situation of vigorously promoting the construction of ecological civilization and improving the ecological environment, the restoration and treatment of mine slopes is imperative, and the stability and safety of the slope are the key to the ecological restoration project of the slope. [0003] It is very difficult to treat the high and steep slope left after mining. It is...

Problems solved by technology

However, these commonly used and mature ecological restoration methods such as spray-mixed vegetation technology and three-dimensional vegetation net method are only suitable for gentle slopes with a slope ratio of less than 1:0.75, and for steep slopes greater than 1:0.75. There are defects such as the substrate is easy to fall off, the anti-erosion ability is weak, and it is difficult to build a comprehensive system of substrate vegetation, so the ideal ecological effect cannot be achieved.
