Abstract

A turbulent waterway, having boats guided in a trough made from bargrating, individual plates of which are connected with each other, the side of the trough being covered with a dense synthetic plastic film.

Claims

1. A trough for a turbulent waterway comprising:

(a) a bottom surface constructed of bar grating;

(b) two side walls constructed of bar grating;

(c) said side walls being loosely connected to said bottom surface and extending upwardly therefrom; and

(d) said bottom surface and said side walls having an overlying synthetic film for providing a watertight environment.

2. A trough as claimed in claim 1, wherein:

(a) said side walls are inclined with respect to said bottom surface.

3. A trough as claimed in claim 1, wherein:

(a) said bottom surface and/or at least one of said side walls are constructed of at least two bar grates which are themselves loosely connected to one another.

4. A trough as claimed in claim 1, wherein:

(a) said side walls are connected to said bottom surface by mortar.

5. A trough as claimed in claim 1, wherein:

(a) sheet metal is provided to said side walls between said bar grating and said synthetic film.

6. A trough as claimed in claim 5, wherein:

(a) said sheet metal extends upwardly from said bottom surface, and above said side walls to thereby provide upwardly extending water retaining edges.

7. A trough as claimed in claim 1, wherein:

(a) said bottom surface is provided with a center guide member which is adapted to control lateral displacement of a boat riding in said trough; and

(b) said guide member is positioned between two control surfaces of said boat.

8. A trough as claimed in claim 7, wherein:

(a) said center guide member is flat.

9. A trough as claimed in claim 8, wherein:

(a) said center guide member is supported on said bottom surface.

10. A trough as claimed in claim 9, wherein:

(a) said center guide member is secured to said bottom surface by bolts; and

(b) said bolts pass through integral bushings of said bar grating of said bottom surface.
