Abstract
A method and apparatus for repairing a water main break are provided. The apparatus includes opposed clamping members actuated by a handle and fastening mechanism. The apparatus may be temporarily positioned at least partially around a break in a water main to thereby contain water gushing out of the break, until a permanent repair band may be positioned over the break.
Claims6
A temporary clamping apparatus for repairing a water main, the apparatus comprising:
- (a) opposed curved clamping arms configured to closely conform to extend more than half way around the circumference of a pipe;
- and
- (b) a fastening mechanism including a handle which, upon rotation, causes the opposed clamping arms to close relative to each other, thereby to clamp the apparatus to the pipe.
A method for repairing a water main, the method comprising:
- (a) placing a temporary clamp apparatus over a break in a live water main, to substantially contain the water gushing from the break, wherein the temporary clamp apparatus includes opposed curved clamping arms configured to extend around and closely conform to the water main, and a fastening mechanism including a handle which, upon rotation, causes the opposed clamping arms to close relative to each other, to thereby clamp the apparatus to the pipe;
- (b) placing a permanent repair band around the main, adjacent the clamp;
- (c) sliding the clamp and band simultaneously to position band around break;
- and
- (d) tightening the repair band to fully repair the break.
