某污水处理站复用水池上浮事故的分析与处理

针对某污水处理站水池出现的上浮现象,从水池整体抗浮稳定验算和局部稳定验算两方面分析了水池上浮原因,并得到了地下水位最低控制线.提出采用井点降水、底板注浆、贮水池混凝土柱补强、石灰挤密桩处理四周土体等方法对水池进行抗浮处理.实践表明,该处理方案抗浮效果好,且具有造价低廉、技术可行性强的优点,水池经抗浮处理后满足使用要求.

Analysis and Solution of Floatation of a Cistern in a Sewage Treatment Station

Aimed at the floatation of cistern in a sewage treatment station,the reasons for the floatation of cistern were analyzed in terms of anti-floating check and local stability check of total cistern,and the control line of the minimum water level was obtained.The well point ground-water lowering,floor grouting,concrete pile reinforcing,lime compaction pile for treatment of soil around the cistern were used to solve the floatation of cistern.The practice shows that the treatment scheme has good anti-floatation ...
