Background
At present, the erosion undercut of the channel in loess plateau areas in China is severe, the erosion of the cut groove of the slope and the channel is undercut, great influence is generated on the instability of the slope and the channel, the water and soil loss in the slope and the channel is serious, and the generated high-sand-content water flows converge into the river channel, so that the sediment content of the river channel is increased. The slope surface trenching treatment is an important part for trench treatment and trench bed fixation, and the slope surface trenching treatment reduces the convergence of slope surface trenching production, prevents the bottom of the trench from being undercut, stabilizes an erosion base point, and further greatly reduces the trench erosion and the trench bank collapse.
The sand blocking dam, the siltation dam and the check dam are main measures for channel treatment, and the sand blocking dam and the siltation dam are mostly built in a main ditch or a larger branch ditch and are not suitable for treatment of slope ditch cutting. The check dam is generally arranged in a small branch ditch and can be applied to slope ditch cutting and scour prevention treatment, but the mortar stone check dam has large investment and is very inconvenient to arrange a drainage channel during construction; the two side banks of the dry masonry check dam are seriously scoured, the top is easy to damage, and the investment is small but the management is inconvenient; the erosion resistance of the soil check dam is poor, and the soil check dam is easy to damage under the condition of heavy rainstorm.
