随着公路桥梁和高层建筑在我国的飞速发展,钻孔灌注桩技术也在不断发展且积累了丰富的施工经验。由于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,施工中任何一个环节出现问题将直接影响整个工程的质量和进度,甚至造成严重的经济损失。因此,在施工过程中必需有效地控制好钻孔灌注桩的施工技术以保证桩基质量。 With the rapid development of highway bridges and high-rise buildings in our country, the technology of bored pile is also developing continuously and accumulated rich construction experience. Because most of the construction of cast-in-situ bored piles is carried out underwater, the construction process can not be observed and the excavation and acceptance can not be carried out after piling. The problems in any part of the construction will directly affect the quality and progress of the whole project or even Cause serious economic losses. Therefore, in the construction process must effectively control the construction technology of bored piles in order to ensure the quality of pile.
