压力注浆在已有建筑物地基加固中的应用

Application of pressure slip casting in ground strengthening of existing buildings

结合工程实例 ,阐述了之所以在已有建筑物地基加固中采用压力注浆的原因 ,对压力注浆加固过程中 ,压力的大小如何确定 ,压力注浆液的稠度与压力大小的关系怎样把握 ,单孔的注浆量与孔隙率的比例如何确定等问题进行了总结。同时在加固过程中还采取了其它一些措施 。

Combining with engineering examples, the paper elaborates cause of adopting pressure slip casting in ground strengthening of existing buildings, summarizes the problems of how to decide pressure big and small, how to master relations of pressure slip casting liquid consistency and pressure big and small, how to decide the proportion of single hole slip casting quantity and porosity in the course of pressure slip casting strenthening. At the same time, some measures else are taken in the course of strenthening, for example of installing curtain in order to separate connections of ground soil and the outside.
