注浆技术在溶洞地基处理中的应用

Application of Grouting Technology in Karst Cave Foundation Treatment

摘要:

在电厂老厂房扩建时地基需要进行注浆加固。根据现场实际情况，针对溶洞地形的地质特征，选取合理的注浆参数及孔位布置，采用合适的钻进方法及注浆技术对地基进行了注浆加固处理，并提出了特殊情况的处理办法。通过注浆后的检测，证明该注浆加固取得了良好的效果。

Abstract:

In the old powerhouse extension, grouting reinforcement is processed for foundation. According to the site situation and in view of the karst cave geological features, reasonable grouting parameters and the hole position arrangement were selected to reinforce the foundation with appropriate drilling methods and grouting technology; the measures for special situation was also proposed. By the test after grouting, it was proved that the grouting reinforcement was successful.
