Cement-Sodium Silicate Intrusion Strengthening of the Buildings

针对某湿陷性黄土地基上的建筑物墙体开裂的原因,采用了水泥-水玻璃注浆加固方法进行加固,对其注浆范围、注浆深度、注浆材料、注浆工艺进行了设计,沉降及裂缝观测结果表明,利用该法消除了地基湿陷性,增强了地基承载力,地基处理效果良好。

In the light of the causes of the wall cracking of a building on the collapsible loess foundation, the cement-sodium silicate intrusion strengtheni ng method is adopted. This paper designs its intrusion scope, intrusion depth, i ntrusion materials and intrusion processes, and the results of the observations of the settlements and cracks show that the utilization of this method can elimi nate the collapsibility of the foundation and strengthen the bearing capacity an d obtain good foundation treating effect.
