摘要
苏州中润广场在深基坑施工过程中发生了管涌现象,通过对事故原因进行分析,制订了改用大功率潜水泵、加厚垫层、对坑中坑基础底板二次浇筑等安全可靠、合理可行的处理方案,有效解决了管涌问题,为类似深基坑工程抢险施工提供了技术支撑。
The piping phenomenon occurred in the construction of deep foundation pits in Suzhou Zhongrun Square. Through analyzing the causes of accidents,a safe and reliable,proper and feasible treatment scheme of using highpower submersible pumps,thickening cushions and secondary casting of pit in foundation pit was developed,which effectively solved the piping problem and provided technical support for the emergency construction of similar deep foundation pit engineering.
