钻孔灌注桩由于适应性强、成本适中、施工简便等特点,被广泛的应用于桥梁工程及其他工程领域。但因其施工过程无法进行观察,成桩后不能进行开挖验收,故施工中的任何一个环节出现问题,都将直接影响整个工程的质量和进度,甚至给各方造成巨大经济损失和不良社会影响。因此如何防治并处理钻孔灌注桩在钻孔过程中及水下混凝土灌注过程中经常出现的施工质量问题,确保钻孔灌注桩施工质量达到设计要求是保证施工结构主体安全的关键所在。
Bored piles are widely used in bridge engineering and other engineering due to their adaptability, moderate cost and simple construction. However, the construction process can not be observed. After excavation, excavation and acceptance can not be carried out. Therefore, any part of the construction problems will directly affect the quality and progress of the whole project and even cause enormous economic losses and bad social benefits to all parties influences. Therefore, how to prevent and deal with the construction quality problems of bored piles during drilling and in the process of underwater concrete pouring, and to ensure that the construction quality of bored piles meet the design requirements is the key to ensure the safety of the main body of construction.
