Analysis on Common Quality Problem during Prefabrication of Reinforced Concrete Shaft Lining in Vertical Shaft of Mine

摘要

reinforced concrete shaft lining were prefabricated on the ground at one vertical shaft engineering in Tangshan city,and the strength grade of concrete is up to C60. Take this vertical shaft engineering as the example,some problems may be encountered in the process of production of reinforced concrete shaft lining has been discussed.Furthmore, it also puts forward methods to solve the problems available for prefabrication of shaft lining in the future.
