复杂地质条件下智能灌浆技术研究和应用

Research and Application of Intelligent Grouting Technology under Complex Geological Conditions

目前对水电站智能灌浆技术已进行了较多研究和探索,研发了智能灌浆设备,针对常规地质条件开发了智能工艺控制策略。但现有智能灌浆技术缺乏压力敏感、破碎地层的智能控制策略,不适用于复杂地质条件下灌浆施工。对此,依托雄安调蓄库工程,采用实证研究法,针对易抬动、易劈裂等薄弱地层开展了智能灌浆及压水工艺策略研究。现场试验结果表明,该智能灌浆技术适应现场施工需要,能智能完成压水和灌浆施工过程,较好地处理施工过程中的抬动和劈裂情况,有利于保障灌浆工程质量、提高智慧施工水平。

Research and exploration on intelligent grouting technology has been conducted in some hydro-power sta-tions in recent years.Intelligent grouting equipment has been invented and intelligent control strategies for conventional geological conditions have been developed.However,the existing technology lacks the intelligent control strategies for pressure sensitive and weak stratum,and is not suitable for grouting construction under complex geological conditions.Relying on the Xiong'an regulation and storage reservoir project and based on the empirical research method,this paper has carried out researches on new intelligent strategies for weak strata such as lift sensitive and split sensitive.The field test results show that the intelligent grouting technology meets the needs of field construction,in which the water pres-sure and grouting construction process can be intelligently completed,and the lifting and splitting situation can be han-dled.The research is conducive to ensuring the quality of grouting projects and improving the level of intelligent construction.
