摘要
介绍利用回旋钻与旋挖机组合施工工艺,在软土地基条件下的深厚卵石层中施工大直径钻孔灌注桩是一种十分有效的方法,有利于大幅度提高成孔效率、有利于提高工程质量,并对施工中可能出现的问题提出相应的预防措施。
Thee large diameter cast-in-place pile construction technology in the deep,thick pebble by GPS-15 rotary drilling and rotator driver combination is a kind of very effective method,it is helpful for working efficiency,well-completion construction quality.According to specific circumstances may appear to put forward the corresponding prevention measures.
