The adjusting sand conveying device 3 serves as a variable frame and plays a role in preventing sediment accumulation, the inclined frame rods 302 are matched with different adjusting screw hole structures on the side frame rods 301, the river bed diversion structure for hydraulic engineering construction has wider applicability to water areas with different flowing conditions, due to the impact of local turbulence, the shovel surface of the composite elastic shovel 305 can generate certain elastic vibration to prevent accumulation and agglomeration of local sediment, and the nonlinear spring 304 can ensure that local deformation of the composite elastic shovel 305 is not too large to damage the shovel surface of the composite elastic shovel.
The setting of elasticity lug 306 makes the silt before the compound elasticity shovel 305 shovel be cut apart, further prevents silt caking, and shovel bottom tooth 307 makes the bottom of compound elasticity shovel 305 and the clearance of submarine smaller, reduces silt and reveal along the lateral circulation, and semi-rigid curved strip 308 can strengthen the shovel face vibration effect of compound elasticity shovel 305 in little disturbance rivers.
The water flow guided by the guide curved block 106 in the guide screen device 1 flows in a reverse transverse circulation mode, and the vibration effect of the composite elastic shovel 305 in the sand conveying device 3 is regulated, so that loose sediment accumulated in front of the concave shovel of the composite elastic shovel 305 can be blown in the reverse transverse circulation mode, and the effect of purposefully changing the variation trend of the convex and concave sides of a water area is achieved.
