木屑水泥浆在土层灌浆中的应用

Application of Sawdust-Cement Mortar to the Grouting through Solum

在带压力水进行灌浆堵漏施工以处理水库漏水时 ,会遇到土层冒浆问题 .采用木屑水泥浆作为灌浆材料并施以限量灌浆 ,致浆液在流动中保持层流状态而使冒浆土层不再冒浆 ,有效地治理了大坝漏水 .该其方法简单 ,费省效宏 ,可供防堤。

In treating water leakage of reservoir, slurry emitting from solum may occur during leakage stoppage by pressurized water. To adopt sawdust-cement mortar as grouting material and to grout in limited quantity will make the flow of slurry to keep a state of laminar flow. Thus slurry emitting from solum did not occcur any more and water leakage of dam was effectively treated. This is a simple,cheap and effective method which will serve as reference for the engineering of dyke and dam.
