污水场生化池防渗示踪试验研究

Study on anti-seepage tracer test of biochemical pond in sewage field

生化池构筑物出现沉降及不均匀沉降问题时,可以通过加固地基、地面防渗等处理措施解决,但生化池底板是否存在渗漏情况尚不得知,研究通过示踪试验对生化池防渗情况进行检测,结果表明,生化池部分伸缩缝存在渗漏情况;在完成修复工作后进行复测,结果表明,修复效果良好,生化池可以投入使用。该方法是一种有效检测泄漏点的方式,可为构筑物出现同类问题的情况提供经验参考。

The settlement and non-uniform settlement of biochemical pond structures were solved by strengthening the foundation and ground seepage control measures.However,it is unknown whether there is leakage on the bottom of biochemical pond.The seepage prevention of biochemical pond was tested by tracer test.The test results showed that there was leakage in some expansion joints of biochemical pond.After completion of the repair work,the re-test results showed that the repair work was effective and the biochemical pond could be put into use.This method is an effective way to detect leakage points,which can provide empirical reference for similar structures.
