钻孔灌注桩技术是道桥施工建设中一个十分重要的组成部分,其凭借着自身适应性强、施工简便以及经济成本低等优点,如今已经广发使用于各个建筑行业当中。然而,在这些优点的背后,钻孔灌注桩技术本身大多是应用于地上或者水下,而且自身也存在着很大的差异性,这使得其在进行实际施工过程当中,经常发生质量问题和安全事故,这就需要我们加强对钻孔灌注桩技术的把握。基于此,将紧紧围绕着道桥施工中应用的钻孔灌注桩技术这一中心主题,从其技术内涵出发,对其施工前、中、后三个时期的应用进行简要的分析和介绍,以期为相应的具体施工提供一定的指导。 Bored pile technology is a very important part in the construction of the bridge. Due to its advantages of strong adaptability, simple construction and low economic cost, it has been widely used in various construction industries. However, behind these advantages, bored pile technology itself is mostly applied to the ground or underwater, but also has its own great differences, which makes it often occur in the actual construction process, quality problems and safety Accident, which requires us to strengthen the grasp of bored pile technology. Based on this, we will focus on the central theme of the technology of bored pile used in the construction of the bridge. From the perspective of its technical connotation, we will make a brief analysis and introduction of its application in the three periods before, during and after the construction. With a view to the corresponding concrete construction to provide some guidance.
