宝钢炼钢车间转炉基础工程平面尺寸为31.30×90.80M、厚2.5M的整体大型板式结构。在基础下面布置了253根直径为91.44cm,长60M的钢管桩,基础采用225级大流动度混凝土,混凝土量为6910m~2(扣除予留孔),底皮和面部钢筋主要采用φ32@150双向布置,含钢量为100.58kg/m~3。基础工程自一九七九年四月十六日开始打井点,到五月三十一日混凝土浇灌结束。在短短的四十六天时间里,完成了四套井点设备
Baosteel’s steelmaking workshop has a large-scale plate structure with a plane size of 31.30×90.80M and a thickness of 2.5M. 253 steel pipe piles with a diameter of 91.44cm and a length of 60M are arranged below the foundation. The foundation is made of 225-grade high-fluidity concrete with a concrete volume of 6910m~2 (deduction of pre-dwelling holes). The base and the steel bars are mainly made of φ32@ 150 two-way arrangement, steel content is 100.58kg/m~3. The foundation project began drilling wells on April 16th, 1979 and ended on May 31 when the concrete was poured. Completed four well point equipment in just 46 days
