Filed:

Appl. No.:

8/541108

International Classification:

F02B 808

US Classification:

405 81

Abstract:

Migrating anadromous fish, and particularly salmonoid smolts, are guided in or by elongate faster moving channels defined in a body of slower moving water. Ring-like support frames are supported by floats and anchors in a water body at spaced distances along a faster moving channel to be defined. Each support frame carries one or more nozzles that receive pressurized water from a water supply system and disperse that water toward the next spacedly adjacent downstream support frame to define the faster moving channels without use of physical peripheral boundary members. The water supply system may be associated with individual support frames or with a plurality of support frames to receive water from the body in which the faster moving channel is defined and pressurize that water for dispersement. Fish are introduced into the upstream portion of the faster moving channel and instinctively tend to remain within the channel so long as the faster water motion exists therein. The system may be used to direct fish movement through small areas or large dam backwaters and is particularly adaptable to surface oriented fish channelization.

Abstract:

A wall is formed of large, preformed structural slabs containing horizontally extending reinforcing members. The reinforcing members are made interlocking so that adjacent slabs in the same course are locked together horizontally. The slabs are placed in the wall vertically aligned, so that the reinforcing members and locking means (which extend outside the preformed concrete slabs) of slabs of successive courses can be welded together, giving a skeleton of steel which imparts great strength and earthquake resistance to the structure. Preferably, the structure is a silo and the slabs are arcuate.
