Introduction: Key components of flexible waterproof casing, such as casing, pressure plate, flange, retaining ring, waterproof wing ring and flange inner thread. The flexible waterproof sleeve is generally applicable to the buildings with vibration or tight waterproof requirements where the pipeline crosses the wall, so as to avoid the shock. Flexible waterproof casing off

flexibility Waterproof casing Key components casing, pressure plate, flange, retaining ring, waterproof wing ring, flange inner thread. Flexible waterproof casing It is generally applicable to the buildings where the pipeline crosses the wall and is subject to vibration or strict waterproof requirements, so as to avoid the need of shock. Flexible waterproof casing is used in places with high requirements such as civil air defense wall and pool. Deformation is allowed after installation.
After centralized processing, flexible waterproof casing and components are transported to the installation site for installation.
Installation requirements of flexible waterproof casing
The technical requirements of 1) the pipe should be placed in the bottom of the pipe.
2) remove the branch pipe: all the sundries in the socket should be removed and cleaned, because all the accessories will lead to water seepage of the socket.
3) remove the rubber ring and upper rubber ring: the adhesive on the rubber ring should be wiped clean, and the rubber ring should be bent into the "red plum flower" or "8" shape and installed into the socket groove, and gently press along all the rubber rings with hand, or tamp with a wooden hammer or rubber hammer to ensure that each part of the rubber ring is not warped or twisted, and is evenly stuck in the groove.
4) brush lubricant on the outer layer and rubber ring of the socket: the lubricant can be vegetable oil, and the lubricant can be evenly applied on the inner surface of the rubber ring installed at the socket. When applying lubricant on the outer layer of the socket, all the positions of the socket outside the socket line should be evenly brushed.
5) push the water pipe into the socket: during installation, put the socket into the socket and press the socket on the rubber ring in the socket, connect the steel wire rope and chain fall, and tighten the chain fall. In addition, shake the water pipe up and down at the socket end,. Until the socket is inserted into the socket, it is all in place. When installing, the axis line should be in a straight line to prevent the rubber ring from pushing out and endangering the installation.
6) the installation of waterproof casing should be flat, and the water pipes should be in a straight line. When there is skewness, it is necessary to pave from the low to the high, and the socket should face the high position.
7) pipe installation: the method of double chain block parallel force is selected to make the pipe parallel installation.
8) during the pavement construction, after one day's operation, the water pipe at the end shall be installed with temporary end plate, and attention shall be paid to prevent soil sand from being injected into the waterproof casing.
9) after the spigot work is completed, before the backfill, the water in the pipe trench shall be prevented and the pipe body shall be prevented from floating.
10) inspection: check whether the position of the socket meets the requirements: use a probe ruler (or steel ruler) to insert into the gap between the socket and spigot to check whether the rubber ring position is correct.
