固结灌浆是针对岩石的节理裂隙发育,提高基岩抗压强度,减少基岩变形的一种灌浆技术。该技术使用范围广泛,可针对不同的岩体形态特征,既能提高岩体强度又起到良好防渗的作用,因此,对水果隧洞的加固及防渗起双重效果。文章以前坪水库泄洪洞为例,对固结灌浆处理岩体裂隙的施工技术工艺流程进行介绍,为类似工程提供借鉴。
Consolidation grouting is a kind of grouting technology aimed at the development of joint and fracture of rock, the improvement of compressive strength of base rock and the deformation of bedrock. The technique has a wide range of applications and can be used for different rock mass morphological characteristics, which can not only improve the strength of the rock mass but also play a good role in preventing seepage. Therefore, the technology has double effects on reinforcement and seepage prevention of fruit tunnels. Taking the Qianping reservoir spillway tunnel as an example, this paper introduces the construction technology process flow of the consolidation grouting rock mass fissure, and provides reference for similar projects.
