Abstract：Haihe tidal gate project is located at the end of Haihe River,Binhai district,Tianjin.During the period of construction,the flood control and drainage are very difficult in central urban area and Binhai district so that the selection of construction diversion standard is very significant.In particular,the surrounding of the gate is dense with buildings and the available work yard is limited,so the selection of diversion scheme is the most important.Besides,the foundation of the channel is silt,which increases the difficulty of cofferdam type selection and open diversion channel type selection.The design of diversion buildings should consider many factors such as geology,materials and construction schemes.The design standard of diversion and the selection of diversion scheme for construction of Haihe tidal gate were introduced in this paper.The design,construction and operation of the open diversion channel of double row steel sheet pile cofferdam and cement mixing pile steel supporting side wall were also discussed.
