Eco-friendly method that induces the action of separating substances generated by the action of gravity while forming an island and purifies polluted river water with clean river water

摘要

In the present invention, the water gate is elevated and water is elevated only in the state where the water is stored, and a discharge space is formed between the lower end of the water gate and the bottom of the water channel, thereby discharging the lower water of the water storage space preferentially through the discharge space The sedimentation sludge deposited on the bottom of the water storage space is discharged together to form an island that can naturally purify the contaminated river water. It is about eco-friendly construction method of cleansing with clean river water.;The present invention is characterized in that a support structure is installed on both sides of a river to form a water channel therebetween, and a water gate is provided between the both side support structures, the water gate is formed in a plate shape, A plurality of supporting rods supporting the plurality of supporting rods are slidably connected to the supporting rods, respectively, and an operating cylinder capable of raising or lowering the roving gate is rotatably connected between the supporting rods and the bottom portion of the channel, A guide rod is formed on the opposite side of the support base in the longitudinal direction of the support base and the fixed rod is connected between the cylinder rod of the lift cylinder and the drain side of the watercourse through a guide hole, The water gate is caused to rise or fall according to the expansion and contraction, and in the closed state of the water gate, To the ever called Hydro upward lifting the accumulated water in the water storage space, a specific gravity of heavy clean the lower layer can be the first discharge was as to purify the polluted river water.;River, water quality, purification
