国华宁海电厂二期2×1 000MW主厂房框架为清水混凝土结构,施工时采用型钢外箍加强柱模的新工艺,该工艺较传统对拉螺杆柱模加固工艺,有避免螺杆孔修补色差的优点,极大的提高了清水混凝土表面观感。对该工艺的设计、施工、应用效果进行介绍,供类似工程施工借鉴参考。
Guohua Ninghai Power Plant Phase II 2 × 1 000MW main plant frame is a clear water concrete structure, the use of steel outer hoop reinforcement column mode of the new technology, the process than the traditional screw-column mold reinforcement technology, to avoid the screw hole to repair color-difference Advantages, greatly improving the water-clear concrete surface perception. The design, construction, application of the technology are introduced for reference for similar projects.
