浅析水库大坝帷幕灌浆试验施工

Analysis on Curtain Grouting Test Construction of Reservoir Dam

水库大坝灌浆技术主要包括布置灌浆孔,灌浆材料的配置,灌浆压力的控制,灌浆完成的判定及质量检查。为保证施工质量,在灌浆施工现场还需要进行试验,根据试验数据对设计灌浆参数进行调整。为避免水库坝体的渗漏,必需采取防渗加固处理技术。

The grouting technology of reservoir dam mainly includes the arrangement of grouting holes,the configuration of grouting materials,the control of grouting pressure,the judgment of grouting completion and quality inspection.In order to ensure the construction quality,it is necessary to carry out tests on the grouting construction site,and adjust the design grouting parameters according to the test data.In order to avoid the leakage of the dam body of the reservoir,it is necessary to adopt the antiseepage and reinforcement technology.
