锦西化工总厂原盐贮运连体筒仓高27m ,由12个直径12m的单体仓组成。环梁以下壁厚360mm ,环梁以上壁厚为310mm ,设计混凝土强度等级为C25,分两组 ,每组6个单体仓滑模施工。施工时正值暑期 ,最高气温达40℃ ,模板滑升后混凝土保护层厚度内出现蜂窝麻面 ,局部混凝土有拉裂现象
Jinxi Chemical Plant Salt Storage and Transportation Siamese silos high 27m, by 12 12m diameter monomer warehouse composition. Below the ring beam wall thickness of 360mm, the ring beam above the wall thickness of 310mm, design strength of concrete grade C25, divided into two groups, each group of six monomer compartment sliding mode construction. During the construction period, the summer peaked at a maximum temperature of 40 ° C. After the slippage of the template, honeycomb pitted surface appeared in the thickness of concrete cover and the local concrete cracks
