钻孔灌注桩工艺技术和经济评价

Evaluation on Technology and Economy of In situ Concrete Piles

本文就钻孔灌注桩若干工艺技术问题,结合质量检验标准,论述成孔、成桩的质量保证措施。并通过与打入方桩在相同前提下进行造价比较,提出钻孔灌注桩比打入方桩,在建构筑物密集地区使用更显其工艺特长的观点。

Taking technical matters of in situ concrete piles into consideration and combining with the requirement of quality test, this paper mskes investigation on the effective measares in boring and casting of concrete piles.By compari son with the driven piles, the in-situ concrete piles will be more econmical in expense and en3rgy,cspecially in the region covered with concentrated sur rounding structures.
