Problems solved by technology

[0003] The technical problem mainly solved by the present invention: Aiming at the current slope protection using concrete or ecological bag technology which cannot effectively maintain the mixed soil and rock slope, which is easy to cause debris flow, a slope protection method for mixing soil and rock is provided. The present invention mainly places the moss-containing film material in the drilled hole so that it fills the gap, and the present invention can effectively fill the gap between the soil and the rock, so that it can resist the impact of debris flow, and at the same time There is no need to cover it with concrete, etc., which is conducive to ecological greening and protects the surrounding natural environment

example 1

[0021] First remove the impurities on the slope surface and level the uneven slope surface, then spray the slope surface with water until the soil moisture content on the surface of the slope surface reaches 45%; pressurize 4 holes per square meter, and choose a hole diameter of 4cm , a variable-hole aeration hose with a length of 3m, a drill bit matching the hole diameter of the variable-hole aeration hose is installed at one end, and the other end is connected with a pressure charging device, and the drill bit is inserted into the slope land at an inclination angle of 45° On the surface, start the pressure charging device and control the pressure to 8MPa. After all the variable-porous aeration hoses enter the slope, stop the pressurization and take out the variable-porosity aeration hose; then select the aperture to be 2cm and the length to be 3m. The variable hole aeration hose is drilled according to the above-mentioned installation method and pressurized drilling method, a...

Abstract

The invention relates to a protection method for a slope with the mixture of soil and rock, and belongs to the technical field of environmental engineering. The method comprises the steps that firstly, the slope is cleaned flatly and cleanly, four holes are drilled in every square meter of the slope in a pressurizing manner, and then the drilled holes are filled with film materials containing moss; and small holes are drilled in the middles of the drilled holes and filled with sewage, nutrient substances are provided, and after the moss grows to a certain degree, gaps between the soil and the rock are completely filled. The protection method has the beneficial effects that the gaps between the soil and the rock can be completely filled effectively, and the gaps can resist to the impact of debris flow; and meanwhile the concrete is not needed for coverage of the gaps, ecological greening is facilitated, and the surrounding nature environment is protected.

Description

technical field [0001] The invention relates to a soil-rock mixed slope protection method, which belongs to the technical field of environmental protection engineering. Background technique [0002] Slope protection generally uses stone, concrete, blocks, etc. to completely seal the entire slope. Although this can better prevent slope landslides, instability and soil erosion, it is easy to cause visual pollution, is not conducive to ecological greening, and damages the natural environment and ecological vegetation around the slope. Therefore, the method of ecological slope protection has been widely used. use. At present, the commonly used ecological protection technologies for engineering slopes are mainly three types: backfilling (or replacement) alien soil technology, spraying technology and ecological bag technology. However, for slopes where soil and rocks are mixed, the gap between soil and rocks is relatively large, and the mixture of soil and soil is relatively loo...
