摘要
通过分析徐州老城区某工程地质、水文条件及施工难点,对混凝土灌注桩施工工艺进行了对比,得出老城区杂填土内宜采用旋挖钻机施工,而嵌岩灌注桩则宜采用冲击钻成孔。
Through analyzing the engineering geology,hydrological conditions and construction difficulties of the old Xuzhou city region,the paper compares the construction technology of concrete bored pile,and concludes that it is suitable to use rotary driller to transfer the miscellaneous fill in old city region,and it is suitable to use percussion drill for socketed bored piles.
