摘要
由建筑垃圾、矿渣、铁矿礁石等组成的松散地层 ,分布均匀性差 ,孔隙率极大 ,是基坑工程施工的难点之一。针对长江广场杂填土层厚 ,渗透性强 ,地下水补给丰富等特点 ,简要介绍了应用于松散杂填土层的水泥水玻璃注浆防水的设计。
Pit construction in loosely filled ground consisted of construction garbages,mineral wastes,etc.owing to its nonhomogeneity and large pore rates,is one of the most diffcult problems in the waterproofing engineering.Based on the features of deep filled strata, strong permeability and plentiful underground water supply,the design,construction method and effects on chemical grouting for waterproofing in the zone B of Changjiang square are briefly introduced in this paper.
