A flow-disturbing and energy-dissipating full-lining debris flow drainage groove, and a construction method and application of the same
The invention provides a flow-disturbing and energy-dissipating full-lining debris flow drainage groove, and a construction method and application of the same. The drainage groove comprises a full lining drainage groove bottom plate and drainage groove side walls on the two sides thereof. The bottom plate in the middle of the drainage groove is provided with a plurality of energy dissipation piers arranged in a quincunx manner; the height hd of the energy dissipation piers is 1/10-1/5 of the depth H of the drainage groove and is less than or equal to 1m; the energy dissipation piers are shaped as regular quadrangular frustum pyramids or circular truncated cones; the lower bottom surface area of the energy dissipation piers is greater than the upper bottom surface area. Compared with the prior art, the drainage groove can disperse the abrasion caused by debris flow to the groove bottom, reduce the flow speed of the debris flow and weaken the washing and damage to the groove bottom, so that the service life of the drainage groove is prolonged and later repair expenses and operation maintenance expenses of the drainage groove are greatly reduced.
