根据该工程的地质勘察报告,施工现场地下水位位于设计基底标高以下,施工时不须采取降水措施。
施工用水、电等均由建设单位送到现场,施工队自备水表及配电箱。
2.4、工程施工特点
工程量大、工期紧、质量要求高:
本工程是为学生教学楼工程,工程质量特别重要,因此质量标准要求高,要求我们保持严谨的科学态度,精心组织,精心施工。
三、施工总体部署
1、施工组织管理
在工程的整个过程中该公司将全部全面负责协调工程质量、进度、安全及文明施工等工作。
上至公司领导,下至基层施工技术人员,对建好3#教学楼工程有足够信心,也予以充分重视。
为此,由公司主要领导组成工程指挥组,每月或半月在现场召开办公室会议,解决、协调、平衡工程进展工程中有关技术、资金、劳动力、机械等方面的问题,确保工程施工快速优质顺利进行
2、施工顺序及流水段划分
根据该工程的特点,拟将3#楼划分为两个施段,便于两工程的流水施工,穿插工作。
以便运用科学的施工方法在最有效的时间内最好的完成工程。
3、施工工期
根据该工程招投标文件,安排施工工期为300日历天,本项目运用科学的施工方案和合理的施工进度计划,抓住优化施工方案是保证各种目标实行的关键。
初步计划基础确保在40天、主体确保在160天、装饰90天完成,清理10天,总工期确保在300天完成任务。
4、施工质量目标
主体工程确保优良工程,单位工程确保市优工程。
坚持“质量第一求效益,用户至上创信誉”,正确处理好“质量、成本、安全”四者关系。
坚持“三级监理,五步到位”的质量控制标准,消灭返工现象,以工作质量保证产品质量。
5、施工安全
工程施工人员在进入施工现场时必须佩戴安全帽,安全小组负责人必须有关的安全处理手册并要进行施工现场的安全管理,尽量排除一些可能预见的安全事故。
杜绝重大伤亡与火灾事故,一般事故频率控制在0.1%以内。
6、施工现场管理目标
坚持“标准化”长效管理,争创“市级文明工地”。
7、施工组织原则
该工程混凝土数量大、质量要求高,总工期只有10个月,为了保证基础、主体、装修均尽可能有充足的时间施工,保质保量完成任务,应该考虑到各方面的影响因素。
(1)、在时间上的部署原则—按季节施工的考虑
根据施工进度的安排,主体施工期间正值秋季施工,在此期间要做好冬季浇筑混凝土的养护措施,确保主体工程质量优良。
(2)、在空间上的部署原则—按立体交叉施工考虑
为了贯彻空间占满,时间连续,均衡协调有节奏,力所能及留有余地的原则,保证按照总进度控制计划完成,需要采用主体和安装,主体和装修,安装和装修的立体交叉施工。
四、施工准备
1、技术准备
项目经理部技术负责人组织现场技术员、施工员、预算员、质检员认真熟悉图纸,了解设计意图,参加图纸会审。
编制施工组织设计和施工方案:
阐明施工工艺和主要项目的施工方法、劳动力组织和工程进度、质量、安全的保证措施。
收集以前施工的各种经验性资料,针对本工程的特点和难点,编制切实可行的分项施工方案、专项施工方案。
2、施工现场的核对
为了该工程在施工过程中一切能够顺利进行,我认为可以对现场核对采取以下措施:
(1)进入现场后,对现场的土质、轴线、标高、降水情况与有关方面进行交接,并办理相应的手续。
对现场的水源、电源及排水设施进入踏勘、交接,按消防要求设置消防消防环道和消火栓。
建立方格网,保证场地“四通一平”。
(2)对现场的平面控制网点进行交接,根据需要进行导线点加密。
施工现场建立控制网,根据给定永久性坐标和高程,按照施工现场总平面图的要求,进行控制测量,设立永久性控制桩。
(3)按照施工现场总平面图,做好现场的排水以及现场生活、生产的污水排放与处理,同时做好除尘工作,减少粉尘对周围环境的影响。
(4)根据施工现场情况,搭接施工作业用钢筋加工场、木工棚和库房等暂设,做好隔声降噪工作。
(5)加强安全保卫工作,施工现场保安人员加强进出门人员管理制度,非施工现场人员禁止进入现场。
3、施工现场布置说明
3.1、施工道路
根据现场平面布置图和现场的实际情况,按场地内原来的排水方向,对场地进行平整,修筑宽3.5m现场临时道路。
现场路基铺100毫米厚砂夹石,压路机压实,路面浇100毫米厚C15混凝土,纵向坡高2%。
3.2、材料堆放
为了保证现场材料堆放有序,堆放场地进行硬化处理,即钢筋、模板、砂石料、砖、周转材料等浇成一块面积较大的混凝土场地。
材料尽可能按计划分期、分批、分层供应,以减少二次搬运。
主要材料的堆放,应严格按照《施工现场平面布置图》确定的位置堆放整齐。
3.3、施工现场临时用水
现场有直径为100mm市政上水干管,从预留接口施工干线,可满足施工与消防用水。
供水:
水源从建设单位上水管中接出,现场采用直径75mm的供水管径,经供入施工现场管网,管网布置沿现场用水点布置支管,埋入地下50cm深;各施工段用胶管接用,考虑到季节性供水短缺和周围的环境卫生,备蓄水池供施工用水。
排水:
施工现场场地狭窄,为了充分利用现场现有的使用面积,现场所有排水沟均为暗沟,排入建设单位指定的家属区下水管;为保证现场清洁卫生,做到文明工,在混凝土搅拌机站旁挖一个沉淀池,将沉淀池的水用泵抽到排水沟中。
3.4、施工现场临时用电设施
为了满足施工现场临时用电的需要,本工程采用TN—S系统三箱五线制供电,穿过施工场地道路的临时用电线路均用镀锌钢管埋地敷设。
楼层用电线采用桥架临时固定在建筑物柱或墙上,并固定牢固。
总配电分照明和动力二个系统,其中动力供电系统共分为四路,一路送到一台塔架;钢筋加工区及木模加工区为一路;钢筋电渣压焊接专用一路;混凝土搅拌机及混凝土输送泵为一路。
照明分为现场照明、生活区照明和办公室照明三个回路。
总配电间,配电箱、开关箱,均按规定设置漏电保护装置,做到“一机、一闸、一漏、一箱”各配电箱均设门备被锁,并采取防雨措施。
五、施工方案设计
1、确定施工程序
(1)、根据先地下后地上,先结构后装修,先土建后设备的原则,本工程总的顺序为:
基础完成后立即进行回填土,以免影响上部结构施工。
2、施工起点流向
由于施工场地,一次性堆放大量材料,场地有限,应合理利用现场场地,缩短工期,提高效益。
装修工程不分段,采用自上而下的流向进行装修施工,在外装修进行了一段时间后,即以自上而下的流向逐层进行内装修。
3、施工测量控制
3.1、施工测量
(1)定位放线
根据施工总平面图,建立永久性轴线控制点,应注意加以保护,作为建筑施工放线依据。
(2)采用J2经纬仪投测轴线,将原基础部分轴线控制网进行一次全面校正,把所有控制线投设到±0.00板上,并对其进行严格的检查校核,确认无误后,在每个流水段的主轴线埋设两个以上的控制点。
(3)高程传递
根据水准点,用几何方法,在楼内分别设三个水准点,使用自动安平水准仪,两个往返,精确测定水准点高程,使用时须检查核对基点,用垂吊、钢尺配合水准仪进行,同时考虑建筑物沉降引起水准点的高差变化,必要时予以修正。
3.2、沉降观测周期的确定
建筑物建成后会引起基础及其四周的地层产生变形,这种
形在一定范围内是正常的,但超过一定的限度,不仅会影响建
物正常使用,严重时还会危及生命。
为了建筑物的安全使用,对其进行变形观测是一项不容忽视的工作。
在实际工作中,我公司按照《建筑变形测量规程》(JG/T88-97),对于建筑物的有效监测,及时、准确地反映出沉降规律。
根据荷载的变动,可将观测周期分为三个阶段:
第一阶段:
从开始施工到满负荷载。
此阶段的观测周期视施工进度而定,一般约为10天至一个月左右。
第二阶段:
从满荷载至沉降速度
