Based on the dewatering engineering of ultra?large and deep foundation excavation in Tianjin Gaoyin 117 Building which has the first structure height building in China, principle of automatic dewatering technology of mixed well based on communicating vessels effect is revealed by theory analysis and application practice. The key technique of construction, technical characteristics and advantages are summarized. Practical application effect of the dewatering technology is analyzed. Research results show that compared with the traditional dewatering technology, automatic dewatering technology of mixed well based on communicating vessels effect can decrease the number of dewatering well, water pump and staff, optimize the dewatering measurement, improve the precision and effect of dewatering, decrease the dewatering cost. Also the requirements of foundation excavation dewatering are met. So the dewatering technology has significant popularizing value and application prospect.
