海仑宾馆工程的钻孔灌注桩,经过多种方法测试,全部达到Ⅰ类桩和Ⅱ类桩的标准.完工验收后被评为优良项目。经过深基坑土方的大开挖,也验证了钻孔灌注桩的内在质量。应该说海仑宾馆工程的钻孔灌注桩的施工是成功的,得到了同行专家的交口赞誉和一致好评,从而扩大了钻孔灌注桩的社会影响,为钻孔灌注的使用赢得了良好声誉。说实在的,当初在决定选用钻孔灌注桩时,我们心理也不太踏实,所以做了多方案比较和大量试验,特别是在试桩阶段,我们在加强桩的质量管理监督方面做了一些工作,为最终选定超长钻孔灌注桩施工提供了科学数据。下面谈谈在钻孔灌注桩的方案选用和施工方面的一些体会,供行家们研究探讨。一、工程要求及场地概述海仑宾馆系三星级中外合资的涉外旅游宾馆,
The drilled cast-in-place piles of the Hailun Hotel project have passed various tests and all have met the standards for Class I and Class II piles. They have been rated as excellent projects after completion acceptance. The large excavation of earth in deep foundation pits also verified the intrinsic quality of bored piles. It should be said that the construction of bored cast-in-place piles for the Hailun Hotel Project was successful and received the praise and praise of peer experts, which expanded the social impact of bored cast-in-place piles and won a good reputation for the use of bored concrete. To be honest, when we decided to use bored cast-in-place piles, we were not very pragmatic. So we did a lot of program comparisons and a lot of tests. Especially during the trial pile stage, we did a lot to improve the quality management supervision of piles. The work provided scientific data for the construction of the long-selected bored piles. Now I will talk about some experiences in the selection and construction of drilling piles for experts to discuss. I.
