摘要
水工隧洞主要的注浆工程有固结注浆、回填注浆、止水注浆、接触注浆、帷幕注浆、超前预注浆等。从功能上来讲主要分为以防渗堵漏为目的的注浆和以加固地层为目的的注浆,有的注浆工程兼而有之。注浆材料主要有无机系和有机系两类,材料不同,添加剂不同,注浆材料的技术指标也有不同。具有不同浓度、凝胶时间等关键指标的浆材适用的具体注浆工程也有所不同,应择优选用。
The grouting engineering of hydraulic tunnel mainly has consolidation grouting,backfill grouting, sealing grouting,contact grouting,curtain grouting,the pre-grouting etc.,it is divided into seepage plugging grouting and reinforcement strata-grouting or combination of both grouting from functions.Grouting materials have inorganic and organic categories ;Different materials need different additives and different technical indi- cators.The different grout material with different concentrations,consolidation time and other key indicators could be applied in the different grouting engineering.
