Top film water-retaining method for underwater canal lining overhaul
The invention relates to a top film water-retaining method for underwater canal lining overhaul. The top film water-retaining method comprises the following construction process steps: additionally installing a sealing layer on an edge needing to be sealed and a downstream face of a flexible waterproof film respectively, and additionally installing a counter weight on an upstream face; sinking downwards the downstream face of the flexible waterproof film into water, laying the flexible waterproof film on the surface of a canal lining in an area to be overhauled, and exposing the unsealed edge of the flexible waterproof film above the water level of water edge. The waterproof film in the top film water-retaining method disclosed by the invention is low in investment, simple in structure, environment-friendly in material selection, good in water-stopping effect, low in additional load, free from damages to the canal lining, convenient and fast to transport, install and transfer in water, capable of being supported by a floating crane, a movable maintenance cabin and a maintenance gallery, and the like to provide a flexible working space for lining maintenance on the provided working base surface, and also capable of being used as a rush emergency water-retaining curtain for preventing a slide area from expansion.
