Abstract：
Yujiabao Station on the extension line of Beijing-Tianjin intercity railway extension line has a foundation pit of about 21.5 m deep and T-shape diaphragm wall of 62 m deep. Considering dense buildings and complex pipelines surrounding the foundation pit and through survey and pilot construction, a set of construction countermeasures for super-deep T-shape diaphragm wall are established, including SMW triaxial mixer, specially-shaped guide wall and slurry preparation, etc., and construction difficulties are successfully solved.
