It is an eco-friendly method that demonstrates the function of river water purification that forcibly cleanses polluted river water with clean river water by forcibly generating the effect of material squeezing action, material squeezing action and material separating action caused by the action of gravity while forming the island.

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, The water gate plate 80 is lifted upwards to upwardly discharge the clean lower water having a heavy specific gravity, which has been stored in the water storage space, and the water gate plate 80 is continuously bent in the horizontal direction in the shape of W in order to purify the contaminated river water (32); / RTI A vertical support 90 continuously arranged in the form of a triangle is connected to the upper surface of the water level plate 80 at intervals of about 30 cm to 1 m so as to prevent the water level plate 80 from being warped With zoom; And an index member (not shown) is coupled to the horizontal and vertical directions of the water gate plate 80 A cylinder 51 of the lifting cylinder is driven in accordance with the driving of the lifting cylinder 80 in the closed state of the watering door 80 so that the lifting and lowering of the watering door is performed in accordance with the expansion and contraction of the operating cylinder 40, The water level is lowered in the downward direction according to the operation of the control system 100 to shut off the discharge of the river water. When the amount of the river water flowing from the upstream of the river is increased, The checker 101 automatically checks the river water level and sends a signal to the total control system 100 and at the same time the pressure of the hydraulic pressure generated by the operation of the hydraulic system 200 operated by the instruction of the comprehensive control system 100 The cylinder rod 51 of the lifting cylinder connected to the lifting cylinder 50 is extended and the lifting cylinder 80 is automatically lifted. In the case of water, the polluted matter molecules, which are light in weight, are automatically floated to the upper part of the river water due to the effect of the incinerator action and the material trimming action. Which is characterized by the natural action of purifying water molecules with heavy specific gravity by the various actions of gravity, and the forces generated by the action of gravity, Friendly method that cleanses contaminated river water with clean river water.
