U-shaped water retaining cofferdam structure and construction method thereof
The invention discloses a U-shaped water retaining cofferdam structure and a construction method thereof, and relates to the technical field of cofferdam engineering. The U-shaped water retaining cofferdam structure comprises a U-shaped main body and a bottom sealing concrete, the U-shaped main body comprises a first water retaining plate and two second water retaining plates, two ends of the first water retaining plate are respectively in fixed sealing connection with one end of each of the two second water retaining plates, the other end of each of the second water retaining plates is used for being in fixed sealing connection with a lower tower column of a bridge main tower through a water stopping box so as to surround an upstream face of the lower tower column of the bridge main tower, and bottom ends of the first water retaining plate and the two second water retaining plates push against and support a bearing platform of the bridge main tower; and the bottom sealing concrete isused for being arranged at the bottom of the U-shaped main body and sealing a pushing against and supporting part between the bridge main tower and the first water retaining plate and the two second water retaining plates so as to form the water retaining cofferdam structure. The U-shaped water retaining cofferdam structure provided by the invention has the characteristics of low construction cost, short construction period, relatively less interference to a channel and relatively lower impact on channel safety.
本发明公开一种U型挡水围堰结构及其施工方法，涉及围堰工程技术领域，该U型挡水围堰结构包括：U型主体和封底混凝土，U型主体包括第一挡水板和两个第二挡水板，所述第一挡水板两端分别与两个所述第二挡水板的一端固定密封连接，两个所述第二挡水板的另一端均用于通过一止水箱与桥主塔的下塔柱固定密封连接以包围桥主塔的下塔柱的迎水面，且所述第一挡水板和两个所述第二挡水板的底端与桥主塔的承台抵持；封底混凝土用于设在所述U型主体底部，且将所述第一挡水板和两个所述第二挡水板与桥主塔的承台抵持处密封以形成挡水围堰结构。本发明的U型挡水围堰结构，施工成本低，施工周期短，对航道干扰较小，对航道安全影响较低。
