Bridge deep foundation pit cofferdam structure and construction method
The invention provides a bridge deep foundation pit cofferdam structure and a construction method. The bridge deep foundation pit cofferdam structure comprises an outer closed structure and an inner closed structure, the outer closed structure is arranged on the outer side of the inner closed structure in a surrounding mode, the outer closed structure comprises a plurality of first steel pipes which are vertically arranged on the riverbed rock surface and arranged in a closed shape, the common outer side of the first steel pipes is surrounded by a continuous closed first steel plate, the inner closed structure comprises a plurality of second steel pipes which are vertically arranged on the riverbed rock surface and are arranged into a closed shape, the common inner side of the second steel pipes is provided with a continuous closed second steel plate, the adjacent first steel pipe and second steel pipe are fixed through connecting pieces, and a filler is arranged between the outer closed structure and the inner closed structure. The problem that a traditional cofferdam cannot take root on an inclined rock surface is solved, displacement of the cofferdam is effectively prevented, the stability of the cofferdam structure is improved, the strength requirement of the cofferdam for the flood season can be met, the safety of constructors is guaranteed, and safe flood crossing can be achieved.
本发明提供一种桥梁深基坑围堰结构及施工方法，包括外封闭结构和内封闭结构，所述外封闭结构包围设于所述内封闭结构的外侧，所述外封闭结构包括竖直设于河床岩面且排列成封闭形状的多个第一钢管，所述第一钢管的共同外侧包围设有连续封闭形的第一钢板，所述内封闭结构包括竖直设于河床岩面且排列成封闭形状的多个第二钢管，所述第二钢管的共同内侧设有连续封闭形的第二钢板，相邻的所述第一钢管和所述第二钢管之间通过连接件固定，所述外封闭结构和内封闭结构之间设有填充物。本发明解决了传统围堰无法在倾斜岩面扎根的问题，有效防止围堰移位，提高了围堰结构的稳定性，可以满足围堰对汛期的强度要求，保证施工人员安全，能够安全渡汛。
