5、合现场勘查情况,作出此下施工方案。1.1项目概述(1)****二期地下室工程施工的主要工作内容如下:a、机械旋挖成孔灌注桩:桩径为φ800和φ1000;b、旋喷桩:桩径为φ600;该工程本工程具有施工难度大,工序多、技术含量高、风险控制要求高等特点。(2)编制验收依据《混凝土结构工程施工工艺标准》(GB50204-2002)、《混凝土结构施工质量验收规范》(GB50204-2002)、《建筑地基基础工程施工工艺标准》26 (GB50202-2002))第二章工程总体筹划2.1工程目标确定1)工期目标按业主工期要求及主要工程量,制定合理的施工工期,以合
6、同规定工期为准。2)质量目标杜绝一切质量事故,分项工程一次验收合格率100%,分部工程优良率85%以上,工程总验收质量达到合格等级。3)安全目标杜绝一切因工重伤事故,轻伤年负率控制在3‰以下,杜绝一切重大机械破坏事故和火灾事故。2.2施工指导思想以参加过类似的工程的管理技术作业人员为施工队伍,组建项目部,根据本工程的重点、难点采用可靠实施性强的施工技术对策,由项目经理全权组织实施,按ISO9001程序控制精心施工,达到优质低耗、安全、文明、按期完成本工程任务。2.3主要施工机械设备序号名称规格单位数量1旋挖钻机S250台12旋喷钻机150台13焊机批12.4施工安排(施工顺序详见施工进度
7、计划)本工程应根据上级要求及实际力量,积极地、科学地组织施工。26 由于单单以基础旋挖桩和旋喷桩为主,故本工程工期控制在6月份完成(详见附见施工进度计划)。在旋挖桩和旋喷桩施工过程中,要组织平行流水、交叉作业,充分利用时间、空间。配套工程项目应同时安排,相互衔接。施工总部暑两部份分为2个阶段。旋挖桩第一阶段:工期为6天,分别为对现场进行施工准备和施工测量。旋挖桩第二阶段:工期为28天,分别为钻机
