Abstract

1398240 Inflatable dams NATIONAL RESEARCH DEVELOPMENT CORP 22 June 1972 [29 June 1971] 30495/71 Heading E1H An inflatable dam 6, Fig. 2, has a tension member 17 with anchors 18 which restrain the dam against horizontal forces, the member 17 being held down against the river bed by suction developed under a seam 16 by open pipes 20 laid in the river bed. The pipes apply the reduced pressure from the lower pool 9 to the area 22. The same effect may be produced by laying on the river bed a layer of graded particulate material, if such does not occur naturally. Fig. 4 shows a double construction in which holding suction can be produced at either side of the dam 6.
