Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with specific embodiments.

[0018] Medium-intensity erosion area: On the catchment slope at the head of the ditch, excavate a horizontal bamboo ditch in the shape of Pin, with a depth of 40cm, a bottom width of 30cm, a surface width of 50cm, and a length of 100cm. Base fertilizer is applied in the ditch to plant tea. Eliminate and store surface runoff, scientifically regulate and rationally utilize surface runoff, control soil erosion, and prevent water from entering ditches. Due to the serious erosion of the topsoil and the barrenness of the inner soil in the Goutou catchment area, during site preparation, the topsoil should be backfilled or basal fertilizer should be applied in places with good site conditions, and soil improvement measures should be implemented to quickly restore vegetation. In the landslide scour area where the terrain is broken, the slope is cut and graded, that is, excavated f...

Abstract

The invention relates to a three-in-one slope collapse managing method employing slope management, slope lowering and slope stabilization, which comprises the following steps: (1) slope management: runoff is adjusted and controlled at a ditch head water collecting area, horizontal bamboo joint ditches or scale pits are dug in a triangle shape or big hole soil preparation is carried out, surface soil is backfilled or base fertilizer is applied, and commercial forests and fruits are planted; (2) slope lowering: a slope is chopped and grades are formed at a collapse scouring area with a broken terrain, a step horizontal platform is built on different levels from the top to the bottom, holes are dug and the soil preparation is carried out, the base fertilizer is applied, the commercial forests and fruits are planted, and soil fixing plants are planted outside the holes and on a slope; and (3) slope stabilization: a sand blocking dam is built at a ditch port accumulation alluvial area with a flat ditch bottom and a solid base, and soil is improved, commercial crops are planted or a culture industry is developed at the downstream of an alluvial fan. The three-in-one slope collapse managing method employing the slope management, the slope lowering and the slope stabilization has the beneficial effects that the damage of the slope collapse corrosion can be managed thoroughly; and the ecological benefit, the social benefit and the economic integrative benefit are better.

Description

1. Technical field [0001] The invention relates to a method for comprehensive control of water and soil loss, in particular to a method for controlling collapsing hillocks in a trinity of slope control, slope reduction and slope stabilization. 2. Background technology [0002] At present, the more common method of treating collapse hills is the method of "upper blocking, lower blocking, and medium green", that is, "upper blocking" to open ditches for drainage, "lower blocking" to build sand retaining dams, and "medium green" to plant plants. Their biggest defect is that they failed to systematically rectify the collapse of the collapsed hillock as a whole, and it is difficult to completely eradicate the harm of the collapsed hillock erosion. There are deficiencies in the allocation of various measures in the idea of ​​engineering biological treatment. "Shangban" only emphasizes ditching and drainage, ignoring the allocation of plant measures to control water and soil loss on...
