钻孔灌注桩的施工大部分是在水下进行的,其施工过程无法观察,成桩后也不能进行开挖验收。施工中任何一个环节出现问题,都将直接影响到整个工程的质量和进度,甚至给投资者造成巨大的经济损失和不良的社会影响。因此在施工前要认真熟悉设计图纸及有关施工、验收规范,核查地质和有关灌注桩方面的资料,对灌注桩在施工过程中可能会发生的一些问题进行分析后制订出施工质量标准、验收实施方案和每根桩的施工记录,以便有效地对桩基施工质量加以控制。
Most of the construction of bored piles is carried out underwater, the construction process can not be observed, after the pile can not be carried out excavation acceptance. Any one part of the construction problems, will directly affect the quality and progress of the entire project, and even cause enormous economic losses to investors and adverse social impact. Therefore, before construction, it is necessary to be familiar with the design drawings and relevant construction and acceptance specifications, verify the geological and relevant information on the pile, analyze some problems that may occur in the construction process of the pile, and then formulate the construction quality standards, acceptance and implementation Program and record of the construction of each pile in order to effectively control the quality of pile construction.
