Introduction: Contemporary engineering construction needs to have long-term quality consideration, to be shocked by the erosion of unique natural disasters. This is critical for people and public property. Therefore, the application of some auxiliary materials in engineering construction should also have the index value of these aspects

Contemporary engineering construction needs to have long-term quality consideration, to be shocked by the erosion of unique natural disasters. This is critical for people and public property. Therefore, the application of some auxiliary materials in engineering construction should also have the index value of these aspects, and we use flexibility Waterproof casing For example, let's talk about the seismic grade index value of waterproof casing.
1. In the construction of water supply and drainage engineering, the main water intake facilities and water pipelines in the county-level cities, the main water treatment buildings (structures), distribution wells, water supply pump houses, central control rooms, laboratories, etc. of the water purification plant shall be classified as the type of anti-seismic fortification, and the anti-seismic fortification type shall be classified as the protection type, and the wall surface shall be required to pass through the pipe Flexible waterproof casing And then reduce the vibration reasonably.
2. In the drainage construction engineering, the anti-seismic fortification type of sewage main pipe (including separated road) in county-level city, main water treatment buildings (structures), inlet pump house, central control room, laboratory of main sewage treatment plant, urban drainage pump station, rainwater pump house at overpass of urban trunk road should be classified as fortification type. Flexible waterproof casing should be installed where the wall passes through the pipe, so as to reduce the vibration reasonably. Rigid waterproof casing 02s404 atlas flexible waterproof casing installation environment specific requirements.
Flexible waterproof casing is generally applicable to buildings with vibration or tight waterproof requirements where the pipeline crosses the wall. After the waterproof casing part is processed, the outer wall of the pipe shall be painted with primer (including camphor Dan or cold primer oil). Waterproof casing is divided into rigid waterproof casing and flexible waterproof casing. Flexible waterproof casing is mainly used in areas with high requirements such as civil air defense wall and pool, while rigid waterproof casing is generally used in basement and other places where pipelines should pass through. Shanghai Luoying pipeline equipment Co., Ltd. reminds you to indicate the outer diameter of flexible waterproof casing pipe when ordering. Products larger than DN 1400 and wall thickness greater than or less than 300 mm can be customized.
Requirements for waterproof material of casing:
(1) the waterproof casing atlas shall have quality certificate for section steel, iron parts and welding rod, and the sampling shall meet the standard requirements.
(2) raw materials such as concrete, sand and stone used for later pouring concrete shall meet the design scheme requirements of waterproof reinforced concrete.
Important technical requirements:
(1) the thickness of concrete wall inside the pipe shall be less than 300 mm.
(2) after the waterproof casing part is processed, the outer wall shall be painted with primer once, and the surface anti-corrosion shall be determined by the design scheme. The welding quality of welding is harmful to the actual waterproof effect of wall pipe. Therefore, welding should be carried out by welders with welding qualification certificate according to the requirements of design scheme and professional requirements of steel structure welding.
Important requirements for occupational health examination:
(1) before welding, welders need to do a good job in grounding devices of all kinds of equipment and insulation measures to prevent electric shock injury.
2. Wear a mask to avoid burning smoke and dust.
(3) when welding in the basement and pit, good ventilation should be maintained to avoid pharyngeal gas poisoning.
Key environmental requirements:
(1) flammable and explosive materials should be eliminated around the welding site, or covered and isolated.
(2) the drawings of waterproof casing show that welding in the external diffusion zone of flammable and explosive gas or liquid shall be carried out after the inspection and approval of relevant departments
Shanghai Luoying pipeline equipment Co., Ltd. mainly produces head type waterproof casing. Waterproof casing is divided into rigid waterproof casing and flexible waterproof casing. Flexible waterproof casing is mainly used in areas with high requirements such as civil air defense wall and pool, while rigid waterproof casing is generally used in basement and other places where pipelines should pass through.
