Conclusions
-
1.
The grooveless multisectional gate permits closing openings of any width without dividing the conduit into sevetal smaller openings at the place of gate installation.
-
2.
The absence of grooves and piers improves the hydraulic conditions of the entire conduit's operation.
-
3.
The use of water pressure for operating the gate eliminates the need for powerful hoists.
-
4.
For heads up to 70–80 m the multisectional grooveless mechanical-acting gate without a pressure chamber which does not impose high demands on the accuracy of installing the roller paths and facings of the gate guide, has the greatest prospects.
