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 理論計(jì)算和灌漿模擬實(shí)驗(yàn)表明聚合物穩(wěn)定劑水泥漿液可灌性好,在相同一的灌漿壓力下,聚合物穩(wěn)定劑水泥漿擴(kuò)散半徑明顯大于膨潤土穩(wěn)定劑水泥漿。
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 本課題針對gin灌漿法研制了新型聚合物mac穩(wěn)定劑,該穩(wěn)定劑較膨潤土穩(wěn)定劑配制的水泥漿具有諸多優(yōu)點(diǎn),可成為配制高性能穩(wěn)定水泥漿液的重要技術(shù)措施。
