Abstract：Research purposes: The purposes are to solve the waterproof problem of metro station in rich water and soft soil ground when using single wall lining structure, i.e. using underground continuous wall as the side wall of structure.
Research methods: Taking the design of underground continuous wall as the side wall of main structure of Songhong Metro Station on Line 2 of Shanghai Metro as an example, the researches are done on the waterproof technologies for self waterproof of concrete structure, joint of continuous wall, induction joint, and for the rigid four-plastering coating of crazing resistant mortar, following the ”Technical Code for waterproofing of Underground Works" and ”Code for Design of Metro".
Research conclusions: There are more technical difficulties in waterproofing by application of single wall lining in rich water and soft soil ground than double wall structure , so high quality design and construction are required , for which the joint of underground continuous wall is a key factor. Application of cross-shaped steel rigid water stop joint can meet the requirement of waterproof to the structure. When the joint of continuous wall is aligned with the induction joint, the cross-shaped steel plate coated with butadiene styrene rubber lutein not only makes effect on waterproof, but also meets the requirement of structural deformation for induction joint.
