在桥梁基础施工中,钻孔桩是最普遍的基础形式,而钻孔桩施工的质量是最难控制的,事故发生的偶然性很多,如何防治钻孔桩施工的质量事故,是施工过程关键所在,基础不牢就无法保证工程质量,给结构物将来的投入使用会留下重大安全隐患。通过多年的施工经验对钻孔桩基础施工中容易出现的钻孔桩事故问题进行了原因分析,总结了一些钻孔桩事故和质量缺陷的预防措施。
In the bridge foundation construction, bored piles are the most common form of foundation, and the quality of bored pile construction is the most difficult to control, accidental accident occurred a lot, how to prevent the quality accident of bored pile construction is the key to the construction process , The foundation is not strong can not guarantee the project quality, to the future use of the structure will leave a major security risk. Through many years of construction experience, the cause of bored pile accident prone to appear in the construction of bored pile foundation is analyzed, and some precautionary measures of bored pile accident and quality defect are summarized.
