The most important process in concrete engineering is formwork engineering, which is the infrastructure of concrete engineering. If you do not understand the formwork construction, especially the formwork application of the upper flip component position does not meet the engineering quality requirements, it will not only fail to improve the construction quality of the construction project, but also cause damage to the internal structure of the concrete.
