文章通过工程实例,证明了对于利用砼钻孔灌注桩的拔除,只要是克服桩侧摩阻力,因而与钢管桩相比,钻孔桩不能直接用★动锤有效地震动减阻,对不同地质情况、不同桩径、不同桩长的桩,其减阻方法也多种多样。根据本文所阐述的拔桩方法由于其减阻效果比较理想,又利用了工地上所具备的常规施工设备,工艺简单成本很低,希望能给类此工程作参考借鉴。
Through engineering examples, the paper proves that for the removal of cast-in-place bored piles by using concrete, as long as the frictional resistance of the pile is overcome, compared with the steel pipe piles, the bored piles can not be directly vibrated and drag-reduced by the dynamic hammer, Geological conditions, different pile diameter, pile length of the pile, the drag reduction method is also varied. According to the method described in this paper because of its drag reduction effect is ideal, but also used on the site with the conventional construction equipment, the process is simple and low cost, hoping to give reference for this project for reference.
