论钻孔灌注桩施工的注意事项及预防措施

钻孔灌注桩是一种基础处理工艺,在公路桥梁中有着广泛的应用.钻孔灌注桩属于地下隐蔽工程,施工过程因无法观察,给工程质量控制增加了难度,其施工过程中受到的影响因素较多,施工中的任何一个环节出现问题,都会对工程质量、进度和成本造成较大的损失.因此,必须做好施工前的技术准备和施工准备,把握好钻进和关注过程的施工质量.

Precautions and Protective Measures in Bored Pile Construction

Bored pile is a kind of foundation treatment technology, has been widely used in highway bridge. Bored pile belongs to underground covert engineering, construction process could not be observed, which increases the difficulty of the engineering quality control. The construction is affected by a lot of factors so that any link of the construction will cause large losses in engineering quality, progress and cost if it appears problem. Therefore, technology and construction preparation must be donewell before the construction kegins and it should be necessary grasp well drilling and pay attention to the quality of construction process.
