Method for preventing and controlling geological disaster through flow guide and energy dissipation of mountainous area slope

Abstract

The invention discloses a method for preventing and controlling a geological disaster through flow guide and energy dissipation of a mountainous area slope, and belongs to the field of construction. According to the scheme, a stilling pool is built on the upstream portion of a gully of the mountainous slope, and the water is collected and subject to energy dissipation; a plurality of reserving holes are formed in the side wall of the stilling pool, through connection of a plurality of draining pipes, water gathered into the stilling pool from the side wall of the stilling pool is subject to partial flow guide, the flow guide direction is perpendicular to or approximately perpendicular to the discharge direction of the stilling pool, and the tail ends of the draining pipes are connected into the downstream portion of the gully at the bottom of the slope. On the basis of the conventional energy dissipation measure, the bundled draining pipes are arranged beside the upstream stilling pool, meanwhile, the flow guide effect of the stilling pool is combined according to circumstances, no washing effect on the slope exists, and the positive good effect is generated on reducing of common landslide, debris flow and the like.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a method for preventing and controlling geological disasters by diverting flow and dissipating energy on slopes in mountainous areas. Background technique [0002] Generally, mountain slopes are prone to disasters such as landslides and mud-rock flows under the action of rainwater erosion. At present, for the prevention and control of geological disasters on mountain slopes, the most common measures are slope stabilization and energy dissipation. Load reduction, pressure grouting anchor piles and anti-slide piles are slope consolidation measures to control landslide geological disasters; piers, walls, dams, aprons, stilling pools, etc. are energy dissipation measures to resist floods and the impact of rock and gravel . However, the engineering measures for slope reinforcement are suitable for steep slopes with very steep terrain and extremely complex geological condition...
