General pool in order to prevent water leak out from the wall, required to wear on a pool of water pipes to install waterproof casing, edge water wing ring, then the space between the casing and the pipe is not still leaking, casing pipe and the pipe connection and aprons, this waterproof casing in construction is how to do, we have come to explain:
The production of waterproof casing installation:
1, familiar with drawings carefully before processing production casing and analyzes how to make installation embedded casing.
2, according to the floor plan, structure structure pipe surface figure and building elevation, to determine the length of the casing. According to the water supply and drainage plan and details again, and reference standard atlas to make.
3, water supply and drainage tube should be paid attention to in production, after installation should be completed in a nozzle with walls, beams and columns faces.
4, steel casing must and wing ring around the water stop full welding.
5, electrical casing is installed on both sides of the nozzle should be out of the wall, beam, cylinder 5 cm to 10 cm.
We in the production of waterproof casing, wing ring and the casing thickness should comply with the specification requirements, the waterproof casing wings on both sides of the ring should be double sided full welding, and weld, level off, smooth, without slag, no bubble, no crack. Clean up after welding, the welding slag, two times of anticorrosive paint is brushed again. During installation and application on both ends of the casing steel three sides above clamping fixed and firm, and shall not be skewed.
