Hanging box cofferdam and construction method of hanging box cofferdam
The invention discloses a hanging box cofferdam and a construction method of the hanging box cofferdam, and the method comprises the following steps: a plurality of steel casings and a plurality of leaking stoppage parts are put down to enable the leaking stoppage parts to reach a first preset position; on the basis of the steel casings, a plurality of prefabricated cofferdam blocks are spliced on the water surface to form the hanging box cofferdam; the hanging box cofferdam is lowered to a second preset position, and the depth of the second preset position is smaller than that of the first preset position; and the leaking stoppage piece is lifted until a gap between the steel casing corresponding to the leaking stoppage piece and the prefabricated cofferdam block corresponding to the leaking stoppage piece is plugged. The leaking stoppage piece is firstly put down, and then the leaking stoppage piece is lifted until a gap between a steel casing corresponding to the leaking stoppage piece and a prefabricated cofferdam block corresponding to the leaking stoppage piece is plugged. The operation is simple and convenient, the construction difficulty is greatly reduced, and the labor intensity of constructors is reduced; according to the mode, a steel casing welding bracket in the related technology is replaced, and the risk of underwater operation is effectively avoided.
本发明公开了一种吊箱围堰及吊箱围堰的施工方法，该方法包括：下放多个钢护筒及多个堵漏件，以使所述堵漏件至第一预设位置；基于所述钢护筒，在水面上将多个预制围堰块拼接而形成吊箱围堰；下放所述吊箱围堰至第二预设位置，其中，所述第二预设位置的深度小于所述第一预设位置的深度；提升所述堵漏件，直至封堵所述堵漏件对应的所述钢护筒与所述堵漏件对应的所述预制围堰块之间的缝隙。通过先下放堵漏件，然后提升堵漏件，直至封堵堵漏件对应的钢护筒与堵漏件对应的预制围堰块之间的缝隙。如此操作简单、方便，大大降低了施工难度，降低了施工人员的劳动强度；该方式替代在相关技术中采用钢护筒焊接托架，有效避免了水下作业的风险。
