The pile bottom settlings and pile side slurry cakes generate physiochemical reaction with the injected slurry and then are solidified, thus remarkably increasing unit pile tip and side resistance and showing solidification effect. 桩底沉淤和桩侧泥皮与注入的浆液发生物理化学反应而固化,使单位端阻力和侧阻力显著提高,显示固化效应。
The later grouting technology is none other but a new type technology developed for solving the problems on bottom settlings and slurry cake in slurry protective bored piles. 后压浆技术正是基于解决泥浆护壁灌注桩中沉渣、泥皮问题而产生的一种新型技术。
