| Abstract:For the design and application of tube well recharge in deep foundation pit engineering, the analysis is made on the particularity of recharge well design for deep foundation pit engineering based on environmental control, the comparison is carried out on dewatering recharge seepage of different recharge filters for hanging curtain and the discussion is made on the key factors affecting plane layout of recharge wells and the design of tube well filter. Aiming at the recharge particularity of deep foundation pit engineering, design principles of “two points flow state” control and determination methods of the lift pump pressure control are put forward, the paper also present 3 principles that the injection water quality should meet. |
