摘要
阐述了大直径钻埋预应力混凝土空心桩的特点与施工工艺,该桩型克服了现在常用的混凝土灌桩与预制桩存在的缺陷,确保了桩基础工程质量,且用单桩代替群桩基础,承载力大大提高,经济效益显著。
The paper presents the feature and construction technique of large diameter bored hollow pile of prestressing lorce concrete. This type of pile overcomes the shortcomings of the often used concrete pile filling so as to guarantee the construction quality of pile foundation and increase to a large degree the hearing capacity, which is of great economic profit.
