寒冷地区钻孔灌注桩冬季施工措施的思考

Think on Winter Construction Measures of Bored Piles in Cold Regions

本文针对镇赉县棚改回迁楼长螺旋钻孔压灌混凝土桩的冬季施工,采取了规范工序、覆盖保温、蓄热养护,添加防冻剂等技术措施;钢筋笼制作避免与冰雪直接接触,且加工温度不宜<-20℃,这些冬季施工措施确保了桩基础冬季施工的成桩质量,为类似条件的施工提供了经验。

For the winter construction of the long spiral bored pile in the shed change back to the floor of Zhenlai county,adopt a standardized process,cover insulation,thermos method,adding antifreeze and other technical measures,fabrication of reinforcing cage avoid direct contact with ice and snow,and processing temperature should be not less than-20℃.The winter construction management measures ensured the pile quality of the pile foundation in winter,which can be used for reference in similar projects.
