Abstract

See full text

A mechanism levels and holds down lateral screens on a basin floor having drop pipes. Support plates fit underneath the lateral screens along their length, and bolts on the ends of these support plates can be used to level the screens. Anchor bolts are affixed to the basin floor using known techniques along and between the various screens. Hold-down bars then fit on these anchor bolts and are held by washers and nuts. Ends of these bars hold against the edges of the plates and the sides of the screens to hold them against the basin floor.
