摘要
陕西信息大厦地基为超厚黄土层,其结构性状良好,故选用超长灌注桩基础。成孔时采用泵吸反循环泵送回灌工艺、泥浆护壁。成孔后对孔径、垂直度和沉渣厚度进行了检测。钢筋笼分节制作,现场拼接,吊放后水下灌注混凝土。
The foundation of Shanxi information building is located at super-thick loess layer with desirable mechanics property and therefore super-long bored piling is adopted.When boring hole,injected water is recy-cled to form a protective slurry coating.After examining hole diameter,verticality and sediment thickness steel cage was put there in and then concreting.
