Drainage equipment for grading energy dissipation of debris flow

Abstract

The invention discloses drainage equipment for grading energy dissipation of debris flow. The drainage equipment comprises a V-shaped drainage channel, wherein energy dissipation basins are arranged on the drainage channel every fixed length; an energy dissipation stepped section is connected between every two adjacent energy dissipation basins; a desilting hydraulic hoisting device is arranged atthe bottom end of each energy dissipation basin; a safety protection net is arranged at the bottom end of the drainage channel; and a plurality of prism-frustum-shaped fixed pillars are arranged on the left sides and the right sides of the drainage channel and the energy dissipation stepped section. According to the drainage equipment for grading energy dissipation of the debris flow, the debrisflow can be smoothly drained through the V-shaped drainage channel; the energy dissipation basins and energy dissipation steps perform grading energy dissipation on the debris flow; the safety protection net is utilized to further filter massive stone, trees and the like, which probably cause risks; and at last, the desilting hydraulic hoisting devices work together to clean the debris flow in theenergy dissipation basins, so that mutli-stage energy dissipation and smooth drainage are achieved, and no silt is left. The drainage equipment is stable in mounting and excellent in energy dissipation and drainage effect and can be used repeatedly.

Description

technical field [0001] The invention relates to the technical field of debris flow drainage equipment, in particular to a debris flow drainage equipment for grading and energy dissipation. Background technique [0002] Debris flow is a torrent formed by heavy rain and floods after saturation and dilution of soft soil mountains containing sand and rocks. Its area, volume and flow are large, while landslides are areas of small areas of diluted soil mountains. Typical debris flows are caused by suspended It is composed of viscous mud rich in silt and clay with coarse solid clastics. Under appropriate terrain conditions, a large amount of water soaks the solid accumulations in the flowing water hillside or ditch bed, reducing its stability, and the solid accumulations saturated with water move under their own gravity, forming a debris flow. Debris flow is a disastrous geological phenomenon. Mudslides usually erupt suddenly and violently, and can carry huge rocks. Because of i...

Problems solved by technology

[0008] The Dongchuan trough used in the existing debris flow energy dissipation and drainage equipment is prone to blockage, and the energy dissipation of the V-shaped trough is insufficient. If the drainage is insufficient, danger will easily occur; The bottom of the tank bears most of the gravity of the debris flow, the impact of the bottom is large, and the ability to dissipate energy is limited; the energy dissipation of deep pools with good performance is difficult to clean in the later stage, and it is not conducive to the drainage of the performance process. There is an urgent need for a good energy dissipation performance. A device with strong conductivity and convenient for later equipment cleaning
