盖挖逆作法施工的基坑在顶板施工并覆土完成后,需要进行生产性抽水试验,以地铁项目为例,采用降水井内预置的振弦式孔隙水压计的施工工艺,从而换算出坑内降水井水位变化情况,以保证生产性抽水试验的顺利进行.
Discussion on the Construction Technology of Production Pumping Test for Foundation Pit by Inverted Construction Method
For the basement excavated by the inverted construction method,after the top slab is completed and the soil is covered,a production water test is required.Using a subway project as an example,the construction process involves placing a piezoelectric porosity water pressure gauge in the well to calculate the water level change in the well,thereby ensuring the successful completion of the production water test.
