According to the underwater concrete secondary pouring construction method, a sealing movable device is installed at the bottom of a pump pipe, cone top fixing channel steel and guide pipe bottom side fixing channel steel are connected in a buckled mode to form a one-way rotating structure, and a cone position binding wire movable buckle and a guide pipe bottom side binding wire movable buckle are connected through a binding wire. After the sealing movable device and the pump pipe enter the concrete liquid level and the depth meets the requirement, a crane is utilized to guide a steel wire rope through a steel wire rope and a steel wire rope guide channel steel outside the cone to pull the hollow steel plate cone, so that a binding wire is stressed and broken; the cone top fixing channel steel and the guide pipe bottom side fixing channel steel buckle can only rotate in one direction and can rotate in one direction after a binding wire is broken, so that the hollow steel plate cone is turned over in an outward rotating mode, and due to the fact that the structure which is turned over in the outward rotating mode can be turned out of the concrete liquid level, it is guaranteed that the concrete cannot have the quality problem of pile breaking or slag inclusion.

    本发明公开了一种水下混凝土二次浇注的施工方法,本发明通过在泵管的底部安装密封活动装置,锥体顶部固定槽钢和导管底侧固定槽钢卡扣连接形成单向旋转结构,锥体处扎丝活动扣和导管底侧扎丝活动扣通过扎丝连接。在密封活动装置和泵管进入到混凝土液面内且深度符合要求后,利用吊车经过钢丝绳通过锥体外钢丝绳引导槽钢引导钢丝绳将空心钢板锥体受拉,使得其扎丝受力被拉断,其锥体顶部固定槽钢和导管底侧固定槽钢卡扣由于只能单向旋转,在扎丝被拉断后能够单向旋转,使得空心钢板锥体外旋翻转,由于外旋翻转后的结构能够利于从混凝土液面翻出,进而确保混凝土不会出现断桩或夹渣的质量问题。
