Waterproof Design and Construction Control Technology for SMW Retaining Structure
SMW retaining structures can satisfactorily meet the waterproof requirements for shallow foundation pits. However, it is rather difficult to control seepage in retaining structures for super-deep foundation pits (excavating depth exceeding 15m) due to ground pressure, soil property, equipment performance, and construction control technology. This paper takes the Zhujianglu Station of Nanjing Metro Project as the background. Based on analysis of the cause of seepage in SMW retaining structures of super-deep foundation pits, this paper theoretically makes a design calculation of the thickness and deformation of the watertight wall, and practices seepage control technology during construction. It is shown that the mentioned technical notes of guiding are significant to some extent for design and construction of SMW retaining structures.
