混合浆液在高压条件下对初凝时间的影响研究

Study on mixed slurry on initial setting time under the high confining pressure

在高围压条件下,把改性黏土混合浆液灌注入受损地质体已成为应用最为广泛的注浆方法之一,但因高围压排水条件下浆液初凝时间测试方法的缺失,混合浆液初凝时间研究较为困难,因此通过自主研发的浆液固结试验平台,对高围压条件下改性黏土混合浆液初凝时间进行了相关研究,以指导现场生产。

Infusing modified clay mixed slurry into geological damage under high confining pressure has become one of the most widely used grouting methods.But due to the lack of initial setting time testing method under the high confining pressure and drainage conditions,to study on the mixed slurry initial setting time is difficult.The initial setting time of modified clay mixed slurry under high confining pressure was studied through the self-developed slurry consolidation test platform,so as to guide the field production.
