Abstract
A method for reducing washout erosion to the bottom or the side wall of a barrage ditch caused by turbulence in water flow in hydraulic engineering is characterized in that artificial aquatic plants are adopted in the method; each artificial aquatic plant comprises a body (1) and a cavity (12); the body (1) is columnar and has toughness or flexibility; the cavity (12) is located in the body (1), and the distance between the cavity (12) and the top end of the body (1) is smaller than one-fourth of the length of the body; and the artificial aquatic plants are densely fixedly arranged at the bottom or on the side wall of the ditch. The artificial aquatic plants are low in cost, can effectively reduce water flow impact and turbulence impact, and can effectively protect a dam body.
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
