岩土工程风动注浆系统设计与应用
|
摘要
目前的注浆设备一般采用电驱动,在高瓦斯、易发火、空间狭小条件下使用具有安全隐患,在富水岩层中注浆效果差。通过对注浆浆液扩散情况进行分析,提出调压注浆工艺;在此基础上,根据风驱动特点,改变动力装置,优化打孔拌料注浆等工序,进行注浆设计;研制了风动注浆系统(排水、拌料、注浆、现场评估四个部分),并系统的介绍注浆系统的结构、功能及步骤,具有连续、便携、注浆稳定、注入浆液稳定等特性。以贵州省龙潭组地层中某软岩巷道围岩变形治理为工程背景,结果表明注浆效果良好,效率显著提高;研究成果对注浆工程的应用具有一定的指导作用。
The current grouting equipment generally is driven by electricity, and it has potential safety hazards in the conditions of high gas concentration, easily catching fire, and confined space leading to poor grouting effect in water-rich strata. Through the analysis of grouting fluid diffusion, the pressure regulating grouting process was proposed; On this basis, according to the characteristics of wind driven, the power device was changed, the drilling and mixing material grouting process was optimized to carry out grouting design; The pneumatic grouting system(draining, mixting materials, grouting and field evaluating) was developed, and the structure, function and procedures of the grouting system were illustrated systematically, characterized by continuity, portability, grouting stability and injecting slurry stability. The surrounding rock deformation treatment of a soft rock roadway in Longtan formation of Guizhou province was taken as the engineering background in this research. The results show that the grouting effect was good and the efficiency was improved obviously; and the research results have certain guiding effect on the application of grouting engineering.
