Comprehensive application of leakage detection technology in subway deep foundation pit
In the engineering of deep foundation pit, in order to ensure the safe excavation of foundation pit, the leakage detection of foundation pit retaining structure can be carried out before excavation, with the purpose of proving the water resistance of retaining structure and treating the possible leakage points in advance. During the excavation of the middle air shaft of a city subway, water gushing accident occurred. After the foundation pit was partially back-filled, a series of reinforcement measures were taken to meet the secondary excavation conditions. In order to confirm the reinforcement effect before excavation, the leakage of the middle air shaft reinforcement was comprehensively detected. The results of the secondary excavation of the middle air shaft show that the water resistance of the foundation pit enclosure system revealed by the leakage detection technology is completely consistent with the actual situation, which proves that the technology has a broad application prospect in the field of deep foundation pit leakage detection, and can be popularized in engineering.
