加筋水泥土旋喷锚桩及止水帷幕加钻孔维护桩支护方案,止水帷幕防止外部水源向基坑内的渗透,加筋水泥土旋喷锚桩可通过采用预应力锚索的张拉达到内支撑的作用,这种支护结构工期较短,工程造价较低,不影响地下室结构施工。 Reinforced soil-grouting grouting anchor bolt and water curtain and drilling maintenance bracing program, water curtain to prevent external water infiltration into the foundation pit, reinforced grouting soil grouting can be through the use of prestressed anchor cable Zhang To reach the role of internal support, this support structure shorter duration, lower construction costs, does not affect the basement structure construction.
