某水电站地下厂房优质混凝土施工技术探讨

Discussion on Construction Technology of High-quality Concrete in Underground Powerhouse of a Hydropower Station

优质混凝土就是直接利用混凝土成型后的自然质感,通过增加"倒角、T型"装饰条作为饰面效果,表面外观不进行或简单进行处理后,使其达到免装修效果的混凝土工程。优质混凝土工程中的模板、钢筋、砼浇筑、外观工序均纳入主控项目,质量等级满足优良标准。施工中应尽量避免出现表面蜂窝、麻面、露筋、夹渣等缺陷,做到表面平整、光洁、色泽均匀,使混凝土自身成型后的质感达到免装修效果。

High-quality concrete is a concrete project that directly utilizes the natural texture of the concrete after forming. By adding "chamfering, T-shaped" decorative strips as a decorative effect, the surface appearance is not processed or simply processed to achieve a decoration-free concrete project. The formwork, reinforcement, concrete pouring, and appearance procedures in high-quality concrete projects are all included in the main control project, and the quality level meets the excellent standards. During construction, defects such as honeycomb, pitted surface, exposed tendons, and slag inclusions should be avoided as far as possible, so that the surface is level, smooth,and uniform in color, so that the texture of the concrete itself can be free of decoration effects.
