对煤斗采用现浇混凝土的施工方法,一直是被施工人员视作一个疑难问题,它主要难在模板的安装及支撑上。由于煤斗本身结构荷载上的特点,加上施工工作面小而形成施工荷载的高度集中,因此,稍有疏忽,很可能在浇混凝土的过程中模板发生变形或砸模。所以,习惯采用的煤斗支模方法,不但工作量大,耗用木料多,支模工序复杂,而且施工进度缓慢,影响整个主体框架的进
The construction method of using cast-in-place concrete for the coal hopper has always been regarded as a difficult problem by the construction personnel. It is mainly difficult to install and support the formwork. Because of the structural load characteristics of the coal hopper itself, combined with the small concentration of the construction work surface to form a high concentration of the construction load, it is somewhat negligible that it is very likely that the template will be deformed or die-cast during the concrete pouring process. Therefore, the customary coal hopper molding method not only has a large workload, consumes a lot of wood, but also has a complex mold making process, and the construction progress is slow, affecting the progress of the entire main frame.
