摘要
上海大名饭店扩建工程中采用双液注浆技术 ,利用注入浆体填充土体空隙 ,提高土的抗压强度。实测结果显示 ,锅炉房外墙沉降变形累计值最大为9.09mm ,最小值仅为2.71mm ,远低于设计允许变形值(20mm) 。
In extension works of Shanghai Daming Hotel,sodium silicate mortar injection technique was adopted to fill void in the soil so as to improve the compressive strength thereof.The survey shows the settlement of the wall of a boiler house is ringed from the maximum 9.09 mm to minimum 2.71 mm,far lower than allowed limit of 20 mm.This measure controls the settlement of the neighbouring buildings very effectively.
