Siltation reduction method for reservoir
The invention relates to a siltation reduction method for a reservoir, and belongs to a general method in the field of water conservancy. The IPC of the siltation reduction system is E02B1/00 and E02B9/02. According to the method, a submerged sediment control dam is built in the reservoir to divide the reservoir into a clear water reservoir region and a muddy water reservoir region, a sand conveying culvert is adopted to discharge water flow containing sand far away from the upstream of the dam out of the reservoir, dual purposes of water storage of the reservoir and sand discharging are achieved, and the reservoir precipitation erosion distance is widened; tiny particle silt turning over the submerged sediment control dam to the reservoir region in front of the dam is discharged out of the reservoir through dam flood discharging tunnels in a submersible sand pump reservoir dredging manner; and for wide, shallow and curved deposition forms in the watercourses of the reservoir regions, smooth and straight reservoir river channels beneficial to density flow transport are built in a submersible sand pump sand-excavating dredging manner, and the natural sand discharging effect is improved. The siltation reduction system is suitable for heavy sediment-laden river reservoir building and deposited waste reservoir reformation engineering.
