9、0；地下一层，15#为 18 层，分两条平行线，即坑底部标高-4.45 米，室外地坪标高为1.1m左右。地质勘探显示该地域饱和水位较高，在自然地坪下2m处，该商住楼基地在自然地坪以下3.35m,最深处 6.2m,电梯井在自然地坪以下 6.2m,由于该地域的挖土方较复杂，自地表向下2.4m 是填土，2.4m7m以下属粉质粘土，由于该地段地质较平缓，水位较高，考虑采用双排轻型井点降水，降水效果为最佳，外排井点降地下4.0m以内水位，内排井点降地下4.0m 以下水位。由于该工程工期较紧，暂按单排轻型井点施工，基坑开挖后如上层降水达不到理想效果，立即采取外加 1 排井点降上层水。基坑土方开挖：因挖土方

10、的深度临近沉积土，密度较小，开挖土方坡按 1：0.75 考虑，以保证护坡稳定，增加护坡安全度。二、降水方案选择：本设计施工方案仅适用于河南恒升府第15#和地下车库基坑的降水工程。工艺流程为：先地上后地下，先降水再开挖，然后支护。采用周边布置轻型井点降水和中心部位大口井降深层水方法，15#商住楼周长 140米采用 3 组轻型井点，轻型井点共3 组。基坑开挖后如降水效果不理想，在外排立即增加 1 排轻型井点降文档编码:CB9C1X8W4W2 HO10X5S10V4J8 ZA2J8H2D8S3文档编码:CB9C1X8W4W2 HO10X5S10V4J8 ZA2J8H2D8S3文档编码:CB9C1X8

42、连接，形成完整系统，然后立即抽水，以检查出水和漏气情况，真空泵的真空度是判断井点系统是否正常的标准，一般真空度应不低于550KPa，反复抽停易出现堵塞滤网、抽带泥沙等不良现象，直接影响工程质量。七、确保工程质量的措施a)组织保证措施建立岗位责任制和质量监督制，明确分工责任，落实施工质量控制责任，各岗位各行其职。b)技术保证措施（1）各种原材料均由公司合格供应商供应。（2）井点安装的质量是降水效果能否达到设计要求的关键，公司将选派有丰富经验的技术工人和质检员严格控制井点安装质量，关键环节是控制的重点，如轻型井点深度、成孔直径、滤料投入、管井井管文档编码:CB9C1X8W4W2 HO10X5S10
