The theoretical calculation and simulating tests show that the grouting liquid with the stabilizing agent mac has good groutability . it has higher spreading radius than that used bentonite as stabilizing agent under the same grouting pressure . 4 理论计算和灌浆模拟实验表明聚合物稳定剂水泥浆液可灌性好,在相同一的灌浆压力下,聚合物稳定剂水泥浆扩散半径明显大于膨润土稳定剂水泥浆。
In this work develop is a new type of macromolecule polymer stability agent mac for the gin grouting method . it has strength of cement rock , low drying shrinkage , good groutability and construction convenience over the bentonite stabilizing agent 本课题针对gin灌浆法研制了新型聚合物mac稳定剂,该稳定剂较膨润土稳定剂配制的水泥浆具有诸多优点,可成为配制高性能稳定水泥浆液的重要技术措施。
