inflatable sluice gate plug is a verticle application to plug a gap

This is a good exapmle of how we can work together to solve interesting engineering problems. The water leeking around the side of these steel and concrete gates needed to be stopped. This is how it was done.

I had to hand it to Scott Brill, He came up with the idea of putting water inside of these tubes so bouyancy would not be a factor. The addition of water made this plug work well along the side of these heavy gates. It is a little complicated, but this was a great collaborative project that worked well. Thanks Scott for an interesting project. Scott works for the Walsh Group in Detroit Mi.


Hey Jack,

Thanks for checking in on us. The air bags worked well last year. I was very surprised how tough the material actually was. We had them jammed in some tight spots between concrete and steel with some protrusions and they never popped. We added valves to the bags so we had the option of adding water or air depending on the situation. Worked great! Attached are a few pictures for you.. I will send more if I can dig them up.

Take care!
