| description | The utility model discloses a river bed cofferdam closure gap intercepting device, and belongs to the technical field of hydraulic engineering facilities. The device comprises a plurality of pyramid-shaped frames, one vertexes of the pyramid-shaped frames coincide, and the faces, away from the coincide vertexes, of the pyramid-shaped frames are open. One surface of the device always contacts with the river bottom, so that the device is large in rolling resistance and good in stability; meanwhile, the face, away from the coincident vertex, of the pyramid-shaped frame is open, rolling stones in river water can be conveniently intercepted by the pyramid-shaped frame, and large stone blocks or small prefabricated parts or the like can be conveniently put into the pyramid-shaped frame. The pyramid-shaped frame has an intercepting effect on the filler, the filler is not prone to being washed away by water flow, the weight and stability of the device in the intercepting process are gradually improved along with incr |
