37、目经理部编写1.1 概述一、搅拌桩与逆拱墙支护结构井概述本工程顶管施工用井（工作井、接收井）结构形式采用钢筋混凝土搅拌桩与逆拱墙支护结构井、沉井，其中W8、W9与W12井结构形式采用的是沉井，其余12个井一律采用圆形搅拌桩与逆拱墙支护结构井形式（5个工作井W4、W17、W21、W26、W31，7个接收井W1、W6、W15、W19、W19-1、W24、W28、）。根据本工程实际情况，共设置7个工作井和8个接收井。工作井、接收井有矩形沉井和圆形搅拌桩与逆拱墙支护结构井两种。井壁处预留出管道出入口，工作井D2000管穿过预留直径2600mm的孔，D1000管预留直径1400mm孔，接收井D2000管
38、穿过预留直径2800mm的孔，D1000管预留直径1600mm孔，预留孔在顶管机进出洞前用M10砖、MU10砂浆砌筑封堵，预留孔且要砌筑实，以防井室进水和能更好地承受顶力。搅拌桩采用500搭接100mm，每井采用两排支护，搅拌桩采用32.5R普通硅酸盐水泥作固化剂，水泥用量每米为50kg，水灰比0.5。逆拱墙、后靠墙墙体混凝土及底板均采用C25商品混凝土，垫层100mm厚采用C15混凝土，钢筋均采用HRB335，fy=300KN/mm2，保护层厚30mm。基坑的开挖深度见下表。表1-1 基坑开挖深度统计表工作井号开挖直径（m）开挖深度（m）接收井号开挖直径（m）开挖深度（m）W4811.86W

40、，浇筑底板，进行顶管施工。由于搅拌桩与逆拱墙支护结构井施工时低于地面，时按设计施工图，拱墙顶应高出地面200mm，防止地面水流入井体内，影响顶管施工作业。2、搅拌桩与逆拱墙支护结构井现场布置搅拌桩与逆拱墙支护结构井四周设施工道路，宽度为48m。为保证施工机械设备及文明施工的要求，施工便道铺筑厚0.3-1m（根据每个井现场实际情况铺填）的块石、砂。沿井的边侧搭设钢筋、模板拼装场地及堆场等，在工作井外设置泥浆沉淀池，由于弃土量较大，泥浆沉淀后，弃土应及时外运。3、主要工程量表1-2 搅拌桩与逆拱墙支护结构井主要工程量表序号项 目单 位数 量1土 方 量m34812.42搅 拌 桩m187653搅拌

43、峰期总施工人员人数达到67人，劳动力需求量不小，因此，必须做好一切准备保证劳动力能及时到位，确保施工工期。1、根据目前我司现有施工力量的情况，现与各专业施工队伍联系好，如搅拌桩施工队、土石方施工队伍等，并签订初步协议，保证可以立即入场，马上开工。2、施工开始期间正值秋冬季节，已作好后勤饮食、保温工作，保证劳动力的充沛体力，防止感冒、肠胃不良等疾病的发生，提高工人的营养水平，保证其承担体力活的基本要求。3、由各工区的工长根据各工区开展的工作面计算劳动力的准确需要量，制订详细的劳动力需求表，提交项目经理部进行劳动力的统一调配，既防止劳动力不足引起施工停顿，也防止劳动力过多引起劳动力的浪费。4、加强
44、技术工人的培训工作以及其他劳动力的熟练程度，确保劳动效率。5、项目部工会组织随时掌握施工队伍劳动力的动向，医疗室配备足够的医药，及时对发生疾病的工人进行治疗或转院治疗，尤其针对冬季容易发生的流感、非典事件对工人宿舍区进行定期消毒处理，改善工人住宿条件，确保不发生传染性的疾病而导致劳动力的严重缺失。1.5 机械设备计划及安排与调度一、机械设备计划表5-1 拟投入本工程的机械设备表设备名称及型号制造年份和使用年限现状（新的、良好、破旧的）数量自有、租赁（从何处租？）、准备购买（从何处买？）1、土方机械1.1反铲挖掘机/1m31999.10/5年良好/3台自有1.2自卸汽车/8T1999.4/5年良
