Abstract
Provided is a method for reducing scouring erosion of turbulent flow in water flow to the bottom or side walls of a river ditch in a water conservancy project. According to the method, artificial water plants are adopted, and each artificial water plant comprises a body (1), a tube cavity (11), liquid (10) and a hollow ball (12). Each body (1) is columnar and has toughness or flexibility; each tube cavity (11) is located in the corresponding body, and each hollow ball (12) is arranged in the corresponding tube cavity (11) and can freely move in the tube cavity (11); the liquid (10) is loaded in the tube cavities (11) in a sealed mode, and the volume of the liquid (10) is equal to the effective volume of the corresponding tube cavity (11). The artificial water plants are densely and fixedly distributed at the bottom or on the side walls of the river ditch. According to the method, the manufacturing cost is low, and the water plants can effectively lower the impact of water flow and turbulent flow and effectively protect a dam.
Description
Technical field
The invention belongs to the method preventing the corrosion of current scour in hydraulic engineering stream, particularly relating in a kind of hydraulic engineering for reducing in current turbulent flow to bottom stream or the method for the erosion corrosion of sidewall.
Background technology
In hydraulic engineering, the turbulent flow of current easily occurs that dam, river is washed power corrosion, easily occur bottom dam, river by situation that turbulent flow is emptied, the present inventor finds that when research pasture and water pasture and water in groups effectively can reduce turbulent flow to bottom stream or the impact force of sidewall, pasture and water can reduce the scale (area of single turbulent flow or volume) of turbulent flow, the turbulent flow that script is being formed without the meeting under pasture and water effect under the rocking of pasture and water is broken down into many little turbulent flows, the impact force of these little turbulent flows is less than the impact force of large turbulent flow many, and these little turbulent flows have some counteractings each other, thus reduce turbulent flow in current to bottom stream or sidewall wash away erosion.
But under field conditions (factors); pasture and water are grown up by little; pasture and water must first take root just can grow up and to bottom stream or sidewall shield; but the little pasture and water needing the place protected namely to have turbulent flow to occur under natural conditions cannot take root and will be flushed away; so pasture and water cannot protect stream by the position of turbulent erosion under natural conditions, need manpower intervention.
Again because natural pasture and water take root slowly, so, artificial manufacture pasture and water and stationary arrangement intensive in a large number be fixedly laid on for bottom stream or sidewall to protect bottom stream or sidewall is necessary, can effectively protect the hydraulic engineering of building in stream.
Summary of the invention
For the problem described in technical solution background, the present invention proposes in a kind of hydraulic engineering for reducing in current turbulent flow to bottom stream or the method for washing away erosion of sidewall, having filled up the technological gap of hydraulic engineering circle.
The present invention has following technology contents.
