| Abstract: | In order to solve groundwater seepage problems during Shantou Nangang sluice foundation pit excavation, high-pressure jet grouting pile enclosure test has been processed on the typical geological area, therefore, the reasonable technical parameters of hole spacing, depth, and grouting pressure have been determined. Through site excavation, water injection test and indoor test, all parameters could meet design requirements. This technique has a good effect in seepage control at Nangang sluice foundation pit engineering and enclosure well test plays an important role in determining the reasonable technical parameters. |
