平潭综合实验区坛西大道北段路基工程位于平潭岛中北部,是平潭岛“两纵两横”快速路网系统中一条南北纵贯线的一个标段。由于该线路的原始地貌为海积平原及海湾滩涂,CFG桩作为一种行之有效的软基处理方式被应用在本标段。CFG桩的施工工艺复杂,又是隐蔽工程,施工质量容易受到多方面因素的影响,为保证软基处理的效果,必须严格控制CFG桩各个施工环节,做好施工中的质量控制。
Pingtan Comprehensive Experimental Zone Tanjugao North Road Subgrade Project is located in Pingtan Island in the north, Pingtan Island “two vertical and two horizontal ” expressway network system in a north-south vertical line of a tenders. Due to the original landform of the line is the plains and the beach tidal flats, CFG piles as an effective method of soft foundation treatment is applied to the tenders. The construction process of CFG pile is complex and hidden engineering. The construction quality is easily affected by many factors. In order to ensure the effect of soft foundation treatment, all construction steps of CFG pile must be strictly controlled so as to control the quality in construction.
