Abstract: Relying on the construction of the shield receiving well of the Yellow River section of Huadian Ningxia Lingwu Power Generation Plant to the intelligent centralized heating project(Phase I) of Yinchuan City. Aiming at the difficulties of developed surface water system, saturated sandy strata, rich water content, and sufficient water replenishment in Yellow River, the key technologies for construction of super deep circular shield receiving shaft in water-rich sandy stratum are discussed. Construction technologies for circular ultra-deep ground wall, top-down method construction of the main structure of the receiving shaft foundation excavation, anti-surge and groundwater treatment for ultra-deep foundation excavations in water-rich sandy stratum are put forward to solve the technical difficulties of super deep circular receiving shaft in water-rich sandy stratum.
Keywords: shields; receiving shaft; waterproof; top-down method; dewatering wells; construction
