Introduction: The rigid waterproof sleeve should be installed before the installation of the pipeline, which means that when the pipeline passes through the concrete floor and the general brick wall, the hole will be embedded on the concrete floor generally, and the brick wall can be drilled through the wall hole later. At the floor, before installing the pipeline, drop the line and install the casing. On the brick wall, draw lines and plant

rigidity Waterproof casing It should be installed before the installation of the pipeline, which means that when the pipeline passes through the concrete floor and the general brick wall, the hole will be embedded on the concrete floor generally, and the brick wall can be drilled through the wall hole later. At the floor, before installing the pipeline, drop the line and install the casing. On the brick wall, draw lines, plant support frame, find the slope and install casing.
Rigid waterproof casing Before the installation and use of the pipeline, the appearance, water injection and surface water flushing shall be inspected first, and then the cracks and sand holes shall be checked one by one. Secondly, check all pipe fittings for cracks, sand holes, and whether the wall thickness is uniform. Once again, check whether all sockets are timely, firm and dense. When installing the waterproof sleeve, the pipe slope should be even, no reverse slope is allowed, and the pipeline slope at the entrance and exit of the flat roof should be expanded as much as possible. The pipe installation of waterproof casing shall be set with supports and hangers according to the construction acceptance specification.
Note for installation of rigid waterproof casing: when the upstream water surface is corrosive medium, the plugging raw materials can be selected to block the gap. If the non concrete wall is encountered, the concrete wall should be partially used. The pouring scope should be 200 larger than the wing ring diameter (D5), and the casing pipe must be poured into the wall at one time. The thickness of concrete wall at the place where the pipe passes through shall not be less than 300, or the type of wall thickening on one side or both sides shall be used. The diameter of the thickened part shall be at least D5 + 200. The net weight of casing is calculated by L = 300. If the wall thickness exceeds 300, it should be measured again.
When the rigid waterproof casing pipe passes through the shear wall foundation, beam and special-shaped column of concrete structure, it shall be installed together with the civil engineering. The reason is that the secondary pouring between the casing and the concrete is not easy to handle after the hole is embedded; some cannot be treated, such as installing rigid waterproof casing on the concrete shear wall of basement foundation.
When rigid waterproof casing pipe passes through buildings and structures with waterproof requirements such as regeneration basement, it is set with unique casing. Rigid waterproof casing is common. The thickness of the casing should be strictly welded, and the thickness of the outer flange should be welded strictly. The new lengthened waterproof sleeve is a kind of lengthened waterproof casing made for thickened wall, which can consider the requirements of threading pipe for extra thick wall. Corrosion resistant water-proof casing, which has undergone unique treatment of anti-corrosion materials, can reasonably avoid air oxidation and erosion of waterproof casing.
When rigid waterproof casing pipe passes through regenerating foundation, internal and external walls, floor slab, etc., it can prevent the vibration caused by the pipeline (pressure pipeline, such as water supply and drainage, radiator, etc.) when it is used, and it is also conducive to the installation and maintenance of the pipeline. If the pipeline is set, the diameter of which exceeds the installation pipe, the material and length meet the requirements, and are installed on the foundation, internal and external walls and floor slab, etc The short tube of the regeneration department.
