摘要: 在对掺聚乙烯醇(PVA)纤维补偿收缩混凝土试验研究的基础上,结合设置加强带,改进水池墙板水平筋、加强施工质量监控等技术措施,对某超大地下工业水池进行无缝设计和施工。蓄水试验检测结果表明,水池各区格的实际渗漏水量仅占允许渗漏水量的56%～60%,防渗性能满足水池设计要求,达到了预期效果。

Abstract: On the basis of experimental research about PVA fiber shrinkage-compensating concrete,combined with the technology measures such as expansive reinforce tape,improvement of horizontal bar,construction quality monitoring,the jointless design and construction is successfully carried out for an large-scale underground industry tank．The water storage test results show that practical water leakages of each tank grid accounted for only permits water leakage 56%～60% ,the impermeability can meet the design requirements,and achieved the desired effect．
