就一个注浆施工实例,详细阐述了料石井壁壁后注浆技术的原理和应用。认为:壁后水泥—水玻璃双液注浆方案是处理料石井壁漏水的切实有效的方法,注浆工艺中的砌缝糊堵质量好坏,漏水区段的注浆顺序、注浆孔的布置、注浆管的埋设是否合理及注浆压力的合理控制等,是注浆施工成败的关键。文章对上述技术课题提出了相应的解决方法。
A case of a grouting construction, elaborated the principle and application of the back grouting technology in the material well wall. The conclusion is that the double-liquid grouting scheme behind the cement-water glass is an effective and effective way to deal with the leakage of material in the well wall, the quality of the grouting in the grouting process is good or bad, the order of grouting in the leaking section, Arrangement, the grouting pipe is reasonable and reasonable grouting pressure control, grouting construction is the key to the success or failure. The article put forward the corresponding solutions to the above technical problems.
