钻孔灌注桩是桥梁工程中一种常用的基础形式,是深基础的一种,属地下隐蔽工程,其施工质量难以控制。在施工过程中,桩位常发生偏移钻、孔倾斜等质量问题,因此在施工过程中要严格控制桩位,发生位置偏移后,若不及时处理或处理方法不当,会影响桩基础承载能力,给工程运行带来隐患。文章就此问题从施工过程和施工质量加以阐述。
Bored pile is a commonly used bridge form of basic form, is a deep foundation, is a hidden underground project, its construction quality is difficult to control. During the construction process, the pile position often has the quality problems of offset drilling and hole inclination, so the pile position should be strictly controlled in the construction process. If the position deviation occurs, improper handling or improper handling will affect the pile foundation bearing Ability to bring hidden dangers to the operation of the project. Article on the issue from the construction process and construction quality to be elaborated.
