【摘要】 详细论述了超声波检测立井壁后注浆质量的整个过程 ,通过对不同岩层的六个测区点的超声波测试 ,归纳出超声波测试立井壁后注浆的五种典型规律 ,并用注浆前后水量直接对比法和注浆前后超声波波速提高幅度这两种方法来分析注浆质量和效果 ;最后提出了用超声波检测注浆质量和效果的定量标准 ,这对于推进注浆技术的发展具有十分重要的意义 .更多还原

【Abstract】 The author gives a detailed account of the whole process of testing the quality of vertical shaft subsequent grouting by means of ultrasonic waves and presents five typical laws of the detetion with ultrasonic waves by giving a test to six detection locations in different rock layers.By comparison of water amount before and after the grouting and examining the increased range of sound velocity,it finally comes up with a quantitative criterion for the ultrasonic wave testing of the quality and result of grouting.This will contibute a great deal to the development of grouting technology.更多还原
