所以在这种地层中施工,利用泥浆回灌钻孔技术有效地平衡松散层压力不使其垮塌尤为重要。
So in such a formation construction, it is important to use the technology of drilling mud back to tank to balance the pressure of the loose layer and prevent the borehole collapse.
结果表明,聚合物稳定剂水泥浆动切应力较膨润土稳定剂水泥浆低,其可灌性和扩展半径要优于膨润土稳定剂水泥浆。
The result shows that the polymer stable-reagent cement paste is lower than bentonite stable-reagent cement paste in act-cut-stress, more superior in grouting capability and expanding radius.
