13、87、设计变更单，编号2007第CQ08-G-1138、现场实际情况二、工程概况 1、挡土墙形式本工程为叙永县岩头上景观挡土墙，采用C20毛石混凝土大体积挡土墙，设计选用国家建筑标准设计图集04J008第74页HJB11，地面到顶面高度为713.00米，基础埋深1米，外侧为1:0.1斜面，内侧呈1:0.2斜坡形，顶宽1200，挡墙底宽度37504625，基本形式见下面附图: 衡重式毛石混凝土挡土墙基本断面形式2、挡土墙各分项工程的做法特点及要求挡土墙地基开挖及处理：中风化或强风化地基，开挖过程出现局部风化而造成基础不平整，设计采用砂卵石换填至设计标高（由设计根据开挖后现场的实际地质条件进行决定
14、后再作处理）。模板工程：由于该断面上部呈梯形，基础呈不规则形状，而且施工工期短，采用普通木模板、木方与483.5钢管扣件支撑的体系结构。毛石混凝土工程：挡土墙要求为C20毛石混凝土，毛石强度等级不得低于MU30,毛石掺入量不大于总体积的30%。毛石混凝土挡墙要求每隔10m一道变形缝，变形缝宽度2030mm，缝内沿墙的内、外、顶三边填塞涂沥青木板，塞入深度不小于200mm。挡墙设置泄水孔，孔眼尺寸为100mm，孔眼间距2m米，上下左右交错设置，泄水孔向外坡度为5%，最低一排泄水孔的出水口应高出地面200mm。3、主要特点与施工难点毛石混凝土挡土墙基础开挖场地处于永宁河中，开挖内壁土方深度超过10
15、m，需要放坡较大。挡墙基槽三分之二处于河水中且是淤泥河和普坚石施工困难。 毛石混凝土挡土墙墙体较高，施工操作难度较大，施工工期短。三、施工部署1、 项目组织机构1.1 本工程将全面实行项目部管理施工，工程项目管理是以高效率地实现项目目标为目的，以项目经理负责制为核心，以项目合同和成本核算制为主要内容，并对工程项目进行全过程、全方位的计划、组织、协调、控制的管理制度。1.2 项目经理部将依据建设单位要求和公司对项目的规划和决策，具体制定和实施总体方针目标，包括工期、质量、安全等。项目经理部将受公司的方针目标考核，同时项目经理部还将接受建设单位和社会各方的监督和检查，最终为项目实现目标管理提供保障。1.3 按照公司项目管理组织条例，本项目经理部将在公司总部的控制和协调下进行本工程的施工管理。1.4 充分发挥我单位的优势，积极为用户服好务，保证干出一个重合同守信用，让业主满意的工程。2、岗位职责分工项目经理部主要管理人员配备如下：序号职务职责范围1项目经理项目负责人2项目技术负责人现场施工负责人3安全员现场施工安全负责人4施工员现场施
