Problems solved by technology

[0003] At present, there is no effective method to deal with the silt in front of the dam. Regular use of sand pumps to clean up the silt deposited in front of the dam is often time-consuming and labor-intensive. It is less applicable and less feasible for reservoirs with higher storage levels.

Embodiment Construction

[0028] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0029] Such as Figure 1-6 As shown, the silt collection and treatment system in front of the dam includes the silt collection system 1 at the bottom of the dam, the floating sand and garbage filtration and collection device 2 in the water, the lifting device 3, and the sediment reprocessing device 4;

[0030] The silt collection system 1 at the bottom of the dam includes a grit chamber and a first collection chamber 8; the grit chamber is provided on the folding slope of the dam facing water along the length direction, and the first collection chamber is arranged at both ends of the grit chamber 5 8. A collection box 9 is placed in the first collection chamber 8;

[0031] Described hoisting device 3 comprises two winches that are positioned at the crest of the dam, and each winch is positioned at the directly above corresponding collection box...

Abstract

The invention discloses a system for collecting and treating silt in front of a dam, which comprises a silt collecting system at the bottom of a dam, a device for filtering and collecting floating sand and garbage in water, lifting equipment and equipment for reprocessing the silt. The system can deal with the sedimentation in front of the dam in time. After reaching a certain sedimentation depth, the sediment can be allowed to enter the collection device in time, so that the height of the sedimentation will not increase further, effectively reducing the rate of decline in the storage capacity of the reservoir. The floating sand can also be collected and processed to reduce the amount of sediment deposition, and the cleaned-up sediment and garbage can be pre-screened to achieve the purpose of reuse. According to the two different distributions of sediment, the sediment in the water body in front of the dam is treated separately, and the floating sand is treated by guiding the silt at the bottom of the dam to a specific collection location and imitating the process of whale predation, so as to clean up the front of the dam in time The purpose of silting is more efficient and timely.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and specifically relates to a method of treating the silt in front of the dam in layers according to the different states of the silt in the reservoir in front of the dam, combined with bionics, imitating the process of cetacean predation to treat the floating sand, reducing the A regular sand removal system for the negative impact of silt in front of the dam on the dam. Background technique [0002] The sediment carried in the reservoir is slowed down by the water flow in front of the dam, and the sand-carrying capacity of the water flow is significantly reduced. The sediment carried by the reservoir will gradually sink from coarse to fine, resulting in rapid sedimentation in front of the dam, which is harmful to the safety of the dam and daily life. Operation and management bring great inconvenience. On the one hand, the deposited sediment will generate gre...
