在重庆理工大学南区学生公寓施工建设过程中,挖孔桩出现未知源头的水。为排水进行后续施工,分别从浅桩处、深桩处、花溪河及静湖采样,对水质的主要指标化学耗氧量（CODcr）、总硬度、pH值、固含量等进行了测定。结果表明,挖孔桩水质量总体上比花溪河水好、比静湖水差,可将其排放至花溪河。

During building the southern student flats in Chongqing university of technology,much water whose source couldn＇t be sure appeared in the manual hole digging piles.In order to drain away the water,shallow piles,deep piles,Huaxi River and Jinghu Lake were respectively sampled and analyzed.Based on the key indexes of water quality（including CODcr,hardness,total salinity,pH,total solids,total alkalinity）,the water in piles was better than that in Huaxi River,and worse than that in Jinghu Lake.So the water in the piles should be drained to the Huaxi River.
