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。
Based on the experimental research on the shrinkage-compensated concrete with PVA fibers, the technical measures of strengthening the belt, improving the horizontal reinforcement of the pool wall and strengthening the construction quality monitoring are put forward. construction. The test results of water storage test show that the actual water leakage in each cell of the water tank accounts for only 56% -60% of the allowable water leakage, and the seepage prevention performance meets the design requirements of the water tank, achieving the expected effect.
