摘要
基于北京通州区某项目地下空间混凝土结构逆作施工应用研究,探讨逆作法施工桩柱合一钻孔灌注桩垂直度控制施工技术,主要包括逆作法、桩柱合一、钻孔灌注桩、旋挖钻机、全回转钻机、双经纬仪、减压钻进等。
Based on application of reverse construction of concrete structure in an underground space in Tongzhou District,Beijing,the construction technologies of vertical control of bored cast-in-place pile with integrated reverse construction method are discussed,including reverse construction method,pile column integration,bored cast-in-place pile,rotary drill,full rotary drill,double theodolite,reduced pressure drilling and so on.
