灌浆钻灌一体化工艺实践与探讨
摘要:历来灌浆是由两个不同的工序组合起来的,即成孔与灌浆,成孔由一套钻具完成,灌浆又是由另一套灌浆管系列完成,之间无相联关系。因此,在某些施工区域,可由钻机组与灌浆组分别完成。通过工艺改进后,可将成孔与灌浆改为一个工序,使灌浆质量与效率均能得到提高。介绍了钻灌一体化技术的原理、工艺流程及其工艺特点,并列举了工程实例。
Abstract:Grouting is composed by two independent processes, pore-forming and grouting. Pore-forming is composed by a suit of drilling tool and pipe while grouting composed by injection pipes. In some construction areas both drilling team and grouting team had to bring into operated. Pore-forming and grouting combined into one process can improve both quality and efficiency of grouting after process improvement. The principle of drilling and grouting integration technology and its technological process and characteristics were introduced in this paper and also the engineering practice was illustraied.
