控制性水泥帷幕灌浆止水技术探讨

Discussion on water stop technology by controllable cement curtain grouting

结合福建沿海某工程建设实例,分析了沿海复杂地质条件下深基坑施工止水的难点,介绍了控制性水泥帷幕灌浆的施工工艺、相关控制参数以及其适用范围。

In combination with an example of engineering construction in coastal areas of Fujian ,the water stop difficulties of deep foundation construction under com- plex coastal geological conditions were analyzed, and the construction technique, the related control parameters and its application scope of the controllable cement curtain grouting were introduced.
