钻孔灌注桩作为一种基础形式,具有适应性强、成本低、施工简便等特点被广泛地应用于公路桥梁领域。灌注桩属隐蔽性工程,桥梁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。因此施工中任何一个环节出现问题,都会直接影响整个工程的施工质量和进度,甚至给投资者造成巨大的经济损失和不良的社会影响。本文结合钻孔灌注桩工程施工的前期准备情况以及施工过程中的质量控制措施进行了详细的阐述。
Bored pile as a basic form, with adaptability, low cost, easy construction and other characteristics are widely used in highway bridges. Cast-in piles are concealed projects. Most of the construction of cast-in-situ piles of bored piles is carried out under water. The construction process can not be observed and the piles can not be excavated for acceptance. Therefore, any problems in construction will directly affect the construction quality and progress of the whole project, and even cause enormous economic losses and adverse social impacts to investors. In this paper, the preparation of bored piles engineering construction and the quality control measures in the construction process are described in detail.
