钻孔灌注斜桩施工技术研究

Study on the Construction Technique of Bored Cast-in-situ Battered Pile

相比普通钻孔灌注桩,钻孔灌注斜桩施工难度大,施工设备要求高。针对某港口工程特点及其所设计钢管钻孔灌注斜桩的施工要求,通过钻机与钻具改造、施工工艺等一系列技术措施,保证了桩基础施工的顺利进行,相关的经验与方法值得类似工程借鉴。

Compared with that of ordinary cast-in-situ pile, the construction of bored cast-in-situ battered pile is more difficult and has a higher demand from the equipment. In the construction of bored cest-in-situ battered pile in a port project, the borer and drill used were transformed and special technical measures were adopted, which has ensured a smooth engineering progress. The experience can be consulted by similar engineering later.
