Three Gorges underground power plant tailwater damping well concrete construction technology the Three Gorges underground power plant tailwater damping well slightly has the construction environment, the safe hidden danger to be big, the construction time is tight, overflow surface quality requirement higher characteristic. After the research, determined that uses forms the corbel well circle structure first in the damping well base concrete, then uses the hydraulic pressure slip form in the well circle to construct the formation continuously the plan. After the lining work concrete construction finished, the damping well wall was smooth, the formation quality was high, was under overseeing and the owner unit's approval.

Three Gorges underground power station damping tail water wells concrete construction technology end of the Three Gorges underground power station with the construction of water wells damper on the environment, security risks, tight construction period, the flow of high quality requirements. The study identified a damping wells in the first poured concrete form at the bottom bracket Jingquan structure, then the use of hydraulic sliding Jingquan for forming and pouring the programme. Lining concrete construction has been completed, damping Well smooth wall, forming high-quality, and by the Commissioner of the owners of the units authorized.

Three Gorges underground power station damping tail water wells concrete construction technology

The end of the Three Gorges underground power station with the construction of water wells damper on the environment, security risks, tight construction period, the flow of high quality requirements. The study identified a damping wells in the first poured concrete form at the bottom bracket Jingquan structure, then the use of hydraulic sliding Jingquan for forming and pouring the programme. Lining concrete construction has been completed, damping Well smooth wall, forming high-quality, and by the Commissioner of the owners of the units authorized.

The tailrace damping well of The Three Gorges Underground Power Station has many characteristics such as small environmental construction, big hidden danger,limit construction period, high quality requirements of the cross section. After studying, we decide to use a scheme that pour a bracket well ring which is made by concrete at the bottom of the tailrace damping well first, and then use a hydraulic slipform to form it by continuous pouring on the ring. When the lining concrete construction is finished, the smooth shaft lining of the tailrace damping well and high quality of the forming obtained the accreditation from the overseeing and owner ' s company
