随着我国交通基础设施建设的快速发展,钻孔灌注桩作为一种基础形式以其适应性强、成本适中、施工简便等特点广泛地应用于公路桥梁及其它工程领域。但灌注桩属于隐蔽工程,大部分是在水下进行的,影响灌注桩施工质量的因素很多,质量检查也比较困难,因此对其施工过程每一环节都必须严格要求,稍有不慎或措施不严就会在灌注中产生质量缺陷,断桩就是经常发生且难以处理的病害之一。在此提出了桥梁桩施工过程几种缺陷桩的形成与处治措施,并简要介绍了桥梁桩断的检测与处理。
With the rapid development of transportation infrastructure in our country, bored pile as a basic form is widely used in highway bridges and other engineering fields due to its adaptability, moderate cost and simple construction. However, the bored pile belongs to the hidden engineering, most of which are carried out under water. There are many factors that affect the quality of the bored pile construction and the quality inspection is also difficult. Therefore, every step of the construction process must be strictly required, with some carelessness or measures Impermanence will produce quality defects in perfusion, broken pile is one of the diseases often occur and difficult to deal with. In this paper, the formation and treatment measures of several kinds of defects piles in bridge pile construction are proposed, and the detection and treatment of bridge pile breakage are briefly introduced.
