给咱们的生活都带来的便当有哪些？ What kind of bentons does the cement drainage pipe bring to our lives?
Speaking of cement drainage pipes, I believe that everyone will be familiar with them. As an indispensable building material in urban construction, cement drainage pipes are mainly used in urban underground construction. The effect of its appearance on us is obvious to all of us.
Among so many building materials that can become an indispensable building material in the city, the advantages of cement drainage pipes are very significant. Now let's talk to you about the bento that the cement drainage pipe has given us.
Generally speaking, municipal water supply and drainage, electricity and so on like to use this material. The long time of application, the resistance to external damage is also very objective.
Cement drainage pipe is a hub for the use of urban sewer pipes. It will be used in some underground water channels and some special factories and mines. Its appearance has brought a great effect to our daily life and industrial development, especially for urban construction. In development, its role is obvious to all, but in the process of using cement drainage pipes, there are often sensational conditions. How is it seismic resistant when using cement pipes in underground water channels?
The use of the core drain vibration process of the cement drainage pipe can greatly alleviate the sensation. This process uses semi-dry rigid concrete, the vertical fabric inner mold oscillates and is radially extruded. The amplitude is adjusted to compact the concrete with good oscillating force, so as to obtain C50 high-strength pipe concrete, so that the pipeline's load resistance and impermeability are significantly enhanced compared to centrifugal and suspension roll processes.
In the vertical core-mold oscillating pipe making process, the concrete is rotated and squeezed again in the axial direction after the feeding of the concrete is finished, which more effectively increases the strength and straightness of the nozzle, and the construction device is smooth.
This cement drainage pipe is actually supported by the method of reinforced concrete. Cement and other materials mainly perform its compression resistance function and the bending resistance function is relatively poor. Due to the addition of steel bars, the shear resistance function has been slightly improved, but It must not be compared with steel pipes.
The second is corrosion resistance. This kind of function is favored by the municipal industry. It is conceivable that in general underground pipelines, builders and designers expect to use longer moments. Due to excavation and replacement, the amount of work is relatively large.
After the pipeline is laid underground, it is difficult to see its condition with the naked eye. It must be selected as a sturdy and durable type to ensure that there are no other methods of damage other than external damage.
