Cofferdam water retaining structure for beach bridge foundation construction and construction method
The invention relates to a cofferdam water-retaining structure for beach bridge foundation construction and a construction method, and the cofferdam water-retaining structure comprises a water-retaining cofferdam which comprises a ground water-retaining section and an underground insertion section; the soil retaining cofferdam is arranged in the water retaining cofferdam and comprises a ground soil retaining section and an underground soil retaining section, and a mounting space is formed between the ground soil retaining section and the ground water retaining section; and the interlayer platform is arranged in the mounting space. The interlayer platform is used as an internal support of the water retaining cofferdam, the interlayer platform and the water retaining cofferdam jointly resist the water head pressure at the high water level, and meanwhile the interlayer platform is used as a ground foundation and a mechanical operation platform during soil retaining cofferdam construction; therefore, the interlayer platform is used as a mechanical construction channel, the bored pile foundation and the soil retaining cofferdam are constructed, then bearing platform construction can be carried out after precipitation, the consumption of a bored platform structure and bottom sealing concrete in the bored pile construction period is saved in the construction process, overwater construction is changed into land construction, and construction is more convenient and faster.
本申请涉及一种滩地桥梁基础施工用围堰挡水结构及施工方法，其包括：挡水围堰，其包括地面挡水段和地下插入段；挡土围堰，其设置在挡水围堰内，并包括地面挡土段和地下挡土段，地面挡土段与地面挡水段之间形成安装空间；层间平台，其设置在安装空间内。层间平台作为挡水围堰的内部支撑使用，与挡水围堰共同抵挡高水位时水头压力，同时作为地面基础以及挡土围堰施工时的机械作业平台；从而在层间平台作为机械施工通道，进行钻孔桩基础以及挡土围堰施工，然后在降水后可进行承台施工，使得施工过程节省了钻孔桩施工期间的钻孔平台结构以及封底混凝土用量，而且变水上施工为陆地施工，施工更便捷。
