Problems solved by technology

No matter which method is used, there are some disadvantages: such as direct planting of turf is cumbersome and takes a long time, and the transplanted turf has a large amount of transportation, and the anti-scouring performance after transplanting is weak, and rainwater infiltration and erosion cannot be slowed down for a long time Slope body: Spray grass seeds directly on the slope, which is cheap and easy to construct, but the slope surface does not have the ability to resist erosion, and the grass seeds are affected by rain and wind, so the survival rate is not high. The effect is not obvious; thick-layer substrate grass planting, hanging three-dimensional net grass planting, and planting bags all use carriers to green grass seeds on the slope, which has a good role in stabilizing the slope surface, but thick-layer substrate and hanging three-dimensional netting The cost is high, and the materials used for plastic products such as three-dimensional nets will damage the ecological environment to a certain extent. The rainwater from the planting bags for slope protection seeps and scours the slope from the gaps between the planting bags, and the anti-scouring effect of the slope is not obvious
However, there is no method with many advantages such as low cost, strong erosion resistance, simple construction, strong impermeability, and zero pollution to the environment.

Abstract

The invention provides an ecological slope protection method based on a branch reinforcement and dry hard clay principle. The ecological slope protection method comprises the following steps: flatting a slope surface; taking and sieving clay; taking and processing rice straws; adding water to mix the clay and the rice straws to form a fluidic plastic clay mixture; constructing the slope surface; pressing branches therein; sowing grass seeds through spray sowing; constructing drain holes; covering a geotechnical curing membrane. The ecological slope protection method is low in construction requirement, simple and feasible; the ecological slope protection method is used for controlling shallow slope diseases, the damage caused by rainfall erosion to the slope surface can be effectively reduced, and the slope surface is protected to promote vegetation greening; construction materials, namely the rice straws and thin branches are decomposed for plant absorption, so that resource recycling is realized and the environment is not polluted; therefore, the ecological slope protection method is of great significance for slope protection construction, ecological civilization construction and sustainable development.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering slope protection, and in particular relates to an ecological slope protection method for shallow slope disease treatment. Background technique [0002] A slope is a common landform. A stable slope will benefit mankind and bring a safe environment to people's production and life; but once the slope becomes unstable, the disaster will be very serious. At present, large-scale slope instability has attracted enough attention, but many people have ignored the impact of shallow small-scale slope instability. In addition to the characteristics of suddenness, fast speed, and large number of small shallow slopes, which bring danger to people's lives, property, and travel convenience, there is an old saying that "long dikes collapse in ant nests", and shallow small landslides are even more serious. The main source of instability causing large slopes. Most of the large-scale artificial slopes (fill...
