Waterproof casing installation method.

Flexible waterproof casing is generally in the project of tying reinforcement according to the requirements of the location reserved for the installation of pre-buried. Then the flexible casing is welded to the rebar and fixed.
 
Waterproof casing should be firmly fixed in the rebar frame, no tilt, because once the waterproof casing is poured, it is difficult to move, so in the fixed is to find a good location, before pouring the top of the casing flange pressure plate and seal to remove, to avoid excessive pressure caused by the pressure plate or seal damage, the ends of the waterproof casing using foam or plastic film hood with other flexible materials will be fixed at both ends of the casing Good, to prevent the concrete from falling in the casing when pouring, causing blockage.
 
When pouring must pay attention to the displacement of the casing, do not wait for the phenomenon of displacement or tilt, after the completion of the pouring, wait for the concrete to completely solidify before removing the formwork, and clean up the casing around the fallen concrete, and the casing will be painted with anti-rust paint inside, and so anti-rust paint to dry after the next step in the construction.
