For deep foundation pit construction, if in the condition of shallow buried underwater confined water, the tube well is applied to lower underground water level and different measures are taken for well sealing to ensure the underground water level to be controlled within the scope of the construction requirements.The paper introduces the dewatering construc-tion for deep foundation pit in a project of Shandong and the relative well sealing plan as well as the construction process for the relief well with confined water head.
