S312 type flexible waterproofing casing is a kind of flexible waterproofing casing, it is mainly applied to pipe through the wall in a vibration or have close by the waterproof demand of hardware fittings, general structures production enterprise is developed according to the construction science research institute of design S312, 02 S404 standard atlas of manufacturing. Flexible waterproofing casing wall place in the walls, such as the case of the concrete should switch to concrete walls, and must be a solidified in the casing wall inside; Flexible waterproofing casing was widely used in construction, chemical, steel, water, sewage treatment, and other units.

Instructions S312 type flexible waterproofing casing detailed instructions and the matters needing attention

1, flexible waterproofing casing general through the wall in a vibration or have close by waterproof demand structures.

2, the casing part, after the completion of the processing in the outer wall all brush priming again (primer ZhangDan or cold foundation including oil). Outer anticorrosion design decision by.

3, casing wall wall of wear, such as the case of the concrete walls should switch to concrete walls, its pouring concrete range should be a colorful ring 200 mm in diameter, and must have great will be the casing wall inside and solid.

4, wear the tube of concrete wall thickness should be not less than 300 mm, otherwise should make wall thickness of the side or both sides thickening. The diameter of the thick part minimum should be a colorful large diameter 200 mm

5, flexible waterproofing material weight is the casing casing wall thickness according to the calculation

6, casing welding materials, components with the A3 material production, T42 welding
