Underwater automatic sorting device for riverbed gravel
An underwater automatic river bed sand and stone sorting device is characterized in that a sand storage dam lower than a river bed sand beach is built at a river channel opening or a turning, a vertical gravel fence is installed on the sand storage dam, and a coarse sand sorting screen groove composed of a horizontal fine sand screen and a vertical coarse sand fence is arranged behind the vertical gravel fence; a gravel pool, a coarse sand pool, a fine sand pool and a silt pool are dug at the bottom of a riverbed at the downstream of the sediment storage dam, the fine sand pool is located in the middle of a river channel, the coarse sand pool and the gravel pool are sequentially arranged at the two ends, and a diversion canal and a gate are arranged at the tail end of the sediment storage dam. And a retention wall and a gate are arranged below the silt pit. The anti-silt hydraulic engineering intercepts sand and stones wrapped by flood above river basins, reservoirs, wetlands and other drainage basins, is easy and convenient to operate, safe to use and low in engineering cost, can effectively intercept and recover the sand and stones wrapped by the flood, reduces silt deposition of downstream riverways and water bodies, and improves the construction efficiency. And a large number of high-quality and low-cost gravel resources can be provided for local infrastructure construction.
一种河床沙石水下自动分选装置，其特征在于，在河道豁口或拐弯处，构筑高度低于河床沙滩的拦沙坝，拦沙坝上安装立式砾石栅栏，立式砾石栅栏的后方设置由卧式细沙筛网与立式粗沙栅栏组成的粗砂分选筛槽；在拦沙坝下游的河床底部挖出有砾石池、粗砂池、细砂池、粉沙池，细砂池位于河道中部，两端依次为粗砂池、砾石池，在拦沙坝的末端设置有分水渠和闸门；粉沙池的下方设置挡水墙及闸门。本发明是一种将洪水裹挟的沙石拦截在江河、水库、湿地等流域上方的防淤水利工程，它操作简便、使用安全、工程造价低，能有效拦截回收洪水中裹挟的沙石，减少下游河道、水体泥沙淤积，还能为地方基础设施建设提供大量质优价廉的沙石资源。
