Fore shaft steel cofferdam in deepwater and torrent states and construction method of fore shaft steel cofferdam
The invention discloses a fore shaft steel cofferdam and a construction method.The fore shaft steel cofferdam comprises a guide frame, eight anchor rods, four sets of fore shaft steel pipe piles, water stopping filler, a ring beam structure and a concrete bottom sealing layer, the anchor rods are fixed to a riverbed, the guide frame is welded to the fore shaft steel pipe piles, the fore shaft steel pipe piles are fixedly connected with the anchor rods, and the concrete bottom sealing layer is fixed to the guide frame. The invention further discloses a construction method of the fore shaft steel cofferdam, the method comprises the steps that the fore shaft steel pipe piles are inserted and driven through the guide frames, underwater concrete is used for sealing the bottom after a ring beam structure is arranged on the inner side of the cofferdam wall, construction can be completed, gaps can be filled with materials expanding when encountering water, and the risk of water leakage is reduced; the guide frame is used for positioning and implementing accurate piling, and the locking steel pipe piles located at the four corners of the guide frame serve as positioning piles in the torrent water area, so that the risk of pile body deviation during piling in the torrent water area is reduced or eliminated.
本发明公开了一种深水急流状态下的锁口钢围堰及施工方法，其中锁口钢围堰包括导向框、八个锚杆、四组锁口钢管桩、止水填充物、圈梁结构和混凝土封底层，锚杆固定在河床上，导向框与锁口钢管桩焊接，锁口钢管桩与锚杆固定连接，止水填充物设置在锁口钢管桩之间的连接处，本申请还公开了锁口钢围堰施工方法，该方法包括：通过导向框插打锁口钢管桩，围堰壁内侧设置圈梁结构后水下混凝土封底即可完成施工，遇水膨胀的材料可填充缝隙降低漏水风险，使用导向框定位实施精确打桩，并将位于导向框的四个角的锁口钢管桩作为在急流水域的定位桩，减小或清除了在急流水域打桩时桩体偏移的风险。
