Comprehensive ecological prevention and control structure and prevention and control methods of high and steep slopes in easily weathered soft rock

Abstract

The invention discloses a comprehensive ecological prevention and control structure for high and steep slopes of easily weathered soft rocks, which includes at least one hierarchical ecological prevention and control structure. and a two-way drainage board, the internal drainage pipe is inserted inside the soft rock slope through the soft rock solidification layer, the two-way drainage board is laid on the surface of the soft rock solidification layer, and the two-way drainage board communicates with the internal drainage pipe; On the surface of the drainage board, an ecological concrete layer and a planting concrete layer are sequentially laid outward. The two-way drainage board is formed by splicing a plurality of shallow two-way drainage blocks, and the shallow two-way drainage block includes a drainage board wall, a drainage channel, a water guide hole and a drainage pipe hole. And on the high and steep slope of easy weathering soft rock, the soft rock slope is excavated step by step from top to bottom, and the easy weathering soft rock high and steep slope comprehensive ecological prevention and control structure is adopted on the excavated soft rock slope Weathered soft rock high and steep slopes are treated. Excellent drainage effect and good protection effect.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and relates to a comprehensive ecological prevention and control structure and a prevention and control method for high and steep slopes of easily weathered soft rocks. Background technique [0002] The failure of high and steep soft rock slopes is a cyclical and gradual instability process. Under the action of rainfall, light and heat, the surface layer of high and steep soft rock slopes is easily weathered and broken, resulting in shallow instability of high and steep soft rock slopes; The new section formed after the high and steep rock slope becomes unstable is weathered and destabilized again under the action of rainfall, light and heat, and this cycle causes the gradual shallow layer instability of the high and steep soft rock slope from the surface to the inside. At the same time, during the excavation process of the high and steep soft rock slope, a large amount of abandoned sof...
