Combined cofferdam structure and construction method thereof
The invention discloses a combined cofferdam structure. The combined cofferdam structure is characterized in that the cofferdam structure comprises a circle of closed annular concrete secant piles (1), wherein the concrete secant piles (1) are buried in a sandstone layer (2) and a pebble soil layer (3), a plurality of bridge concrete piles (4) are distributed in an array mode within the range defined by the concrete secant piles (1), the bridge concrete piles (4) are buried in the sandstone layer (2) and the pebble soil layer (3), bottom sealing concrete (5) is further arranged in the range defined by the concrete secant piles (1), a bearing platform (6) and piers (7) are arranged above the bottom sealing concrete (5), top beams (8) are arranged at the tops of the concrete secant piles (1), and the top beams (8) are connected with a double-wall steel cofferdam through pre-buried steel components (9).
本发明公开一种组合围堰结构，其特征在于：所述的围堰结构包括一圈封闭环形的混凝土咬合桩（1），所述混凝土咬合桩（1）埋设在砂岩层（2）和卵石土层（3）中，在混凝土咬合桩（1）合围的范围内，阵列式的分布有多根桥梁混凝土桩（4），且这些桥梁混凝土桩（4）也埋设在砂岩层（2）和卵石土层（3）中，所述混凝土咬合桩（1）合围的范围内还设置有封底混凝土（5），所述封底混凝土（5）的上方设置有承台（6）和桥墩（7），所述混凝土咬合桩（1）的顶部设置有冠梁（8），冠梁（8）上通过预埋钢构件（9）与双壁钢围堰（10）连接。
