摘要
武汉中央商务区黄海路(二期)工程,设有内支撑的基坑全长约217m,宽约为35~70m,深度约为0.5m^14.2m,维护形式采用钻孔灌注桩+内支撑、双排SMW工法桩+内支撑、放坡形式,内设一道钢筋混凝土内支撑,钢筋混凝土内支撑量截面为1000mm~*1000mm、800mm~*800mm。局部换撑。在拆除该内支撑结构时,采用了"金刚石绳锯切割钢筋混凝土内支撑"的施工方法,取得了良好的效果。
In the Huanghai Road(Phase II)project of Wuhan Central Business District,the foundation pit with internal support is about217m in length,35~70m in width and0.5~14.2m in depth,the maintenance form uses bored pile+inner support,double row SMW method pile+inner support and grading form.There is a reinforced concrete inner support whose cross-section area is1000mm*1000mm,800mm*800mm.The support is changed in local part.In the removal of the inner support structure,it uses the construction method of"diamond wire saw cutting steel reinforced concrete support",and it has achieved good results.
