4、水的浸泡,加上A-02地块的雨水排不出,致使车库基础被地下水淹没,车库基础施工场内有大片积水和淤泥,需换填约1.0米厚左右的石渣以提高现场地基承载力,才能保证现场施工。2、本次场平主要实物工程量 1) 范围及面积约:18358.17m2 2)总填方约:14686.54m3 3) 总弃方约:14686.54 m3 4)填(取)土运距为约:12.0KM,弃土运距约:15Km 为确保按业主方要求的工期完成施工任务,我司特制订以下施工方案进行施工。五、施工部署1、A-02地块主楼、车库施工面积约19000m2,车库冲桩328根,车库场区内施工的建筑物为G16、G17、G18、G19、G11,场区有一主

5、施工便道从车库场区横穿。根据主体建筑物施工进度和不影响施工便道车辆通行的原则,对车库施工区域进行划分;我公司承建的车库划分为四个施工区域,分别如下G16主楼区域为1区,G18主楼区域为2区,G19主楼区域为3区,余下部分为4区。在施工过程中为保证施工质量,采取分施工区域分批换填。A-02地块车库划分平面图2、在G16、G17、G18、G19、G11主楼施工时,加上汉丰湖蓄水造成车库、区域积水,基底土质软化,淤泥层深度约1.0米。为了保证该区域冲桩机进场施工,确保车库的施工进度对该施工区域的淤泥质土进行抛石挤淤。3、抛石挤淤的石块采用万达高速公路隧道开挖的砂岩弃渣,选用的砂岩石块粒径为100-5

6、00mm,距离我司车库施工区域15Km;先将车库、区域内淤泥质土清除,清除淤泥厚度0.8m;然后分层回填石渣,每层石渣回填厚度0.4m,每层用20T挖掘机来回碾压平整,石渣总的回填厚度0.8m。六、主要分部分项工程施工方法 1、排水 采用用二台功率为7.5KW、直径150污水泵,由工人轮班昼夜连续不间断抽水。2、场外取石渣回填 地表积水用水泵抽干后进行回填土。从场外约12.0KM处取挑选合格的砂岩石渣,用小松240型挖机一台挖装石渣,粒径控制在100-500mm,用10辆20T红岩渣土车运至现场回填,回填要分层并用小松240型挖机碾压平整,填至标高约174.8米处,以提高现场地基地承载力,为现

7、场布置“三通一平”提供条件。3、弃土外运 待桩基础施工完毕后,进行地梁施工前,再将运来填实的石夹土用小松240型挖机装运至渣场,平整至车库地坪标高174.0米,以进入下道工序施工,弃土运距15KM。七、人员、材料、机械设备的组织1、项目管理人员的组织参与本工程施工的管理人员均是我公司的业务骨干,项目部管理人员职责分工明确,协同配合,在项目经理的领导下,项目部全面负责现场的施工、技术、质量、安全、核算等工作,并根据作业计划和施工预算提出劳动力、材料机具需用计划,统一指挥生产,保证本工程的工期、质量、成本、安全和文明施工等各项控制目标和各项经济技术指标的实施2、 施工机械布署:根据现场实际情况,在
