在现代水利水电工程中,地基施工仍是整个工程的根本性前提所在,因而为了确保灌浆施工技术水平得到有效提升,就必须在整个工程建设过程中,切实加强灌浆施工技术的应用,并针对不同的地基采取针对性的方法进行灌浆,达到加固地基的目的。一、灌浆分类按灌浆目的分为帷幕灌浆、固结灌浆、接触灌浆、接缝灌浆和回填灌浆等。1)帷幕灌浆。是用浆液灌入岩体或土层的裂隙、孔隙,形成防水幕,以减小渗流量或降低扬压力的灌浆。
In modern water conservancy and hydropower projects, foundation construction is still the basic premise of the whole project. Therefore, in order to ensure the effective improvement of grouting construction technology, it is necessary to strengthen the application of grouting construction technology in the whole project construction process, Of the foundation to take a targeted approach to grouting, to achieve the purpose of strengthening the foundation. First, the grout classification According to the grouting purposes into curtain grouting, consolidation grouting, contact grouting, seaming grouting and backfill grouting. 1) Curtain grouting. Is the slurry into the rock or soil fissures, pores, the formation of waterproof curtain to reduce the seepage flow or reduce the filling pressure.
