How to ensure the quality of cement pipes
As we all know, cement pipes are important pipes for the construction of underground facilities in our cities. They are widely used in telecommunications, tap water, urban rainwater and sewage drainage pipes, gas forces, etc., as well as highway longitudinal, lateral drainage and water permeability. The role that cannot be ignored, how can the quality of the cement pipe be guaranteed? Let's take a look together!
1. In the production process of cement pipes, since all of them are operated underground, the harsh environment is unavoidable, and dust flying will definitely occur. To alleviate this situation, dust collection equipment is installed, and then dust flying is avoided. The situation happened.
2. The manufacturing process of the cement pipe is that the joints are not carefully arranged, accumulate in the joints, the joints are misaligned, and the bolts are not consolidated according to the rules. In order to prevent the leakage of slurry, the deformed cement pipe mold should be corrected in terms of equipment. Seriously, it should be screened. The cement pipe mold bolts should be fully equipped. In terms of technology, the inside of the seam should be carefully arranged. Align to prevent misalignment.
3. Different cement products have very different anti-sulfate functions. In general, if quality problems occur in cement pipes, they are affected by aluminate minerals, water-cement ratio, and maintenance temperature. . Through research and exploration, we found that if a certain amount of fly ash is taken into the cement pipe, the quality of the cement pipe can be effectively improved, and the use of fly ash can also protect the environment.
4. In the hot weather or the production of self-stressing cement with fast setting phenomenon, try to shorten the mixing time and the parking time before feeding as much as possible. The "pre-hydration" method or mixing with cold water is used to mix the materials to delay the setting speed, which can deal with the problem of the ribs of the cement pipe.
