Project Design of Dewatering for Deep Foundation Pit in Dalian

Tube well dewatering is widely applied in deep foundation pit for its large water discharge, good dewatering effect, simple equipment and easy maintenance. In this paper, rube well dewatering is designed for the temporary project of foundation pit according to the engineering characteristics and stratum and underground water distribution with the deep foundation pit engineering as the background. The required parameters and design process of well tube dewatering are illustrated, and experience of applying tube well dewatering in evacuation of deep foundation pit is accumulated, which will be of certain referential significance for similar projects.
