Description

[0002] The slope protection structure in the hydraulic engineering refers to the engineering measure for protecting the slope surface of the hydraulic structure such as the river bank, the dam and the reservoir from the erosion and damage of the water flow. The main function of the slope protection structure is to improve the stability of the slope surface, prevent the water and soil loss and ensure the safety and long-term operation of the hydraulic engineering. Due to the scouring effect of the water flow, especially under the extreme weather conditions such as the rainstorm and the flood, the slope surface is prone to the problems such as the erosion and the collapse, and therefore the slope protection structure must have a good scouring prevention effect.

[0003] In order to improve the scouring prevention effect of the slope protection structure, many hydraulic engineering structures choose to lay the concrete prefabricated part on the slope surface to provide the physical barrier, which effectively resists the direct impact of the water flow. However, the concrete prefabricated part can effectively suppress the surface soil and prevent the direct scouring of the slope surface, but cannot improve the internal structure and performance of the soil. Such surface protection measure is prone to the deficiency in the long-term use, especially under the high-intensity water flow impact, the stability of the soil is still poor, which easily leads to the water and soil loss and the damage of the slope surface.
