Maintenance method for large diameter cement pipe
Large-caliber cement pipe is very useful in our daily life. It not only has the characteristics of high bearing capacity, good stability, long service life, etc., but also one of the materials often used in the construction industry. So how should we maintain large-caliber cement What about?
1. The best protection method for cement pipelines in winter is steam curing.
The first requirement is to build a steam curing pond. The steam curing pond can be determined according to its own needs. It also requires the boiler to transport steam to the steam curing pond. The degree of sealing of the steam curing pond is better. After the cement pipe is formed, it can be hoisted into the steaming pond for steaming. Generally, steaming is required for 2.5--3.5 hours. Generally, the higher the temperature, the shorter the time of steaming. The time of steaming is inversely proportional to the temperature of steam. The higher the temperature, the better. Steaming method has fast protection and good effect.
2. Another protection method for cement pipes is natural protection.
After the cement pipe is finished, the cement pipe and mold are placed in the open air for natural protection. Generally, it is necessary to protect the open air at the time of one day, and the mold can be opened the next day. After the mold is opened, natural protection is required for 4--6 days. A special person sprays water on the cement pipe three times a day, usually once in the morning, once in the noon, and once in the afternoon. The purpose of water spray is to adhere to the humidity of the cement pipe so that the concrete can gradually set itself, and the number of water sprays can be added and reduced according to the weather conditions and the humidity of the air.
钢厂出厂前涂的防腐剂或其他镀复及包装，这是避免资料锈蚀的重要措施，在运送装卸过程中须留意保护，不能损坏，可延长资料的保管期限 3. Packaging and protective layer to protect the material The preservative or other plating and packaging applied before the steel factory leaves the factory. This is an important measure to avoid rusting of the material. Pay attention to protection during transportation and loading. It must not be damaged, and the storage of the data can be extended. the term
4.Insist on warehouse cleanliness and strengthen data protection
(1) Before entering the warehouse, pay attention to avoid rain or mixed impurities, and use different methods to wipe the already rained or soiled materials according to their properties. For example, use a steel wire brush with high hardness and low hardness with Cloth, cotton, etc.
(2) Check the data frequently after entering the warehouse. If there is any rust, remove the rust layer.
In the end, we are reminded that even new large-diameter cement pipes require regular protection and maintenance. During the application process, we must properly and rationally use the device in accordance with relevant regulations to allow it to exert its maximum effect.
