Abstract
The invention discloses a method for relieving erosion corrosion of turbulent flow in water flow to the bottom or the side wall of a ditch in a hydraulic project. The method is characterized in that artificial aquatic plants are adopted; each artificial aquatic plant comprises a body (1), a pipe cavity (11) and liquid (10); the bodies (1) are cylindrical and tenacious or flexible; the pipe cavities (11) are located in the bodies; the liquid (10) is contained inside the pipe cavities (11) in a sealed mode; the volume of the liquid (10) is smaller than the effective volume of the pipe cavities (11); the artificial aquatic plants are fixedly arranged at the bottom or the side wall of the ditch densely. According to the method, manufacturing cost is low, water flow impact and turbulent flow impact can be effectively relieved, and the hydraulic project can be effectively protected.
Description
Technical field
The invention belongs to the method preventing the corrosion of current scour in hydraulic engineering stream, particularly relate in a kind of hydraulic engineering and to reduce 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 and to reduce in current turbulent flow to bottom stream or the method for the erosion corrosion of sidewall, filled up the technological gap of hydraulic engineering circle.
The present invention has following technology contents.
