13、案编制: 审核: 审批: 本工程主体基本施工完毕,即将开始进行出渣、管道、设备平台以及护坡分项工程的施工。现对出渣、管道、设备平台以及分化石斜坡的现场具体情况描述如下:1、分化石斜坡垂直向高度H=14.45m,水平方向平均宽度B=10.99m,(0.000m平面外柱外边线至斜坡底的水平距离分别为5.8m;4.1m;3.6m;5.2m;3.5m;1.9m),分化石斜坡仰角约为=52.74度,表面为强分化石。旧压滤楼外侧柱坐落在强分化石的岩石上。2、新压滤楼出渣平台顶标高+7.000m,斜坡底至外柱外边平均宽度B=9.32m(分别为11.2m;10.9m;9.9m;9.5m;9.5m;4.9m),

14、长度L=36.00m,平台有效利用宽度8.12m。3、新压滤楼尾渣直接落至+7.000m平台上以及上部斜坡上,通过装载机装车,机动车运输。旧压滤楼尾渣直接落至原平台,通过装载机铲运至+7.000m平台上再进行装车运输。4、新压滤楼入液管道,阳极液罐、氨水罐、清水灌设备等安装在新旧压滤楼之间3000mm宽度,15.00m长度,+14.470m的平台上。(旧压滤楼原落渣平台标高处)根据上述实际状况,我单位经过技术讨论与计算,绘制出渣、管道、设备平台以及分化石斜坡的施工蓝图并编制此方案进行施工。一、工程概况1、出渣平台顶标高+7.000m,平台平面尺寸36m*8.12m,周圈挡土墙厚度300mm,高

15、度7.00m,混凝土C30,长度约计46.1m;2、挡土墙与斜坡的空隙为C20毛石混凝土,约计2020m3;3、+7.000m平台至+14.450m平台的分化石斜坡采用植筋,铺设钢筋单层网片,浇筑200mm厚C20混凝土;4、+7.000m+10.000m栏板厚度200mm,混凝土C30,长度约计46m;5、由于以下几点实际原因:1)旧压滤楼外侧柱子持力层为强分化石斜坡,基础外侧在新厂房土方开挖后裸露在外,持力层为杂填砂石。2)旧压滤楼z-1柱子的基础坐落在砌筑的杂填石上。3)新压滤楼的工艺要求以及管道安装的设计图纸,氨水罐、清水罐、阳极液罐的安装位置。业主单位决定将新压滤楼内侧柱内边与旧压滤

16、楼外侧柱外边3000mm的空间用C20素混凝土全部浇筑成型,解决了旧压滤楼基础受力要求,新压滤楼管道安装,三台设备的安装等一系列问题。6、其余分化石斜坡长度约计39.00m,宽度约计12.67m,面积为494.31m2。植筋深度800mm,纵横向间距均为1000mm,孔径25,铺设14钢筋网片,间距200,混凝土厚度200mm。7、装载机通道宽度3.50m,垂直高度H=7.00m,坡度为30度斜坡。基础用毛石混凝土浇筑,表面浇筑C20素混凝土200mm厚,25300(L=3.20m)防滑条。所有于尾渣接触的混凝土表面涂刷环氧树脂漆两底两面,颜色为天蓝色。其中+7.000m平台混凝土面层为C20

17、细石耐磨抗酸混凝土。厚度200mm。二、工程管理目标1、质量管理目标要求工程质量达到合格工程标准。我单位的质量目标是:认真贯彻执行国家、省市及各行业现行标准规范、工艺标准,单位工程质量一次验收合格率为 100,争取创优质工程,确保工程质量。2、施工工期目标计划总工期为23天。2012年10月1日开工,2012年 10月23日竣工。3、安全、文明施工管理目标3.1安全目标建立环境、职业健康安全管理体系,杜绝死亡和重伤、重大机械设备安全事故,杜绝职业病重大火灾和爆炸事故的发生,千人负伤率控制在4以内。3.2文明施工目标创建文明工地,认真贯策执行建筑施工安全检查标准-JGJ59-99及建筑施工现场环

18、境与卫生标准-JGJ146-2004;认真按政府建设管理规定执行,保护环境,做到文明施工,现场整齐有序,减少和降低施工噪音和对周围环境的污染,进一步提高企业的整体形象与文化形象。三、施工部署本工程属于二次技术改造工程,施工场地狭小,工期紧,水平运输与垂直运输不便。浇筑混凝土工程量大且为自拌混凝土,浇筑受上部现浇板标高的限制(+23.80m),柱子之间间距(6000mm)的制约,造成新旧压滤楼之间3000mm平台范围内的混凝土无法用吊车来进行垂直运输,同时模板支撑系统加固困难;+7.000m以下外侧挡土墙施工完毕后,内侧毛石混凝土的垂直运输工程量大,强度上升慢,浇筑时机械垂直运输以及水平运输不便

19、,劳动强度大;植筋工程量大,施工技术要求高,难度大。因此,针对出渣平台、管道以及三个罐体安装平台的施工,我方经过认真研究和周密计划,制定了以下几条关键措施:1、出渣平台挡土墙先浇筑至+3.50m。内侧的毛石混凝土石料垂直运输采用挖掘机运输,人工整平,混凝土垂直运输采用70T,25T吊车运输,同时在西侧两跨内的毛石混凝土面预留10%斜坡道,坡底为0.000m。验收合格后,进行+3.50m+7.00m挡土墙浇筑,+3.50m+7.00m的毛石混凝土石料用时风三轮车沿西侧坡道运输至其余三跨内,人工整平,混凝土垂直运输采用70T,25T吊车运输进行浇筑。坡道处剩余毛石混凝土石料与混凝土水平、垂直运输全

20、部采用70T,25T吊车。2、管道平台,三台罐体的平台混凝土浇筑采用时风三轮车直接运输至旧压滤楼+14.47m平台上自卸至浇筑部位,时风三轮车行进的路线不平整者,采用200*300*2500枕木600作为支撑,上面铺设t=18mm厚钢板,保证运输路线畅通安全。3、出渣平台,三台罐体平台的模板加固采用在原分化石斜坡上打孔植筋,孔深800mm1000mm,孔径25mm,植25螺纹钢,外漏200mm,水平,竖向600mm,水平方向焊接14拉杆,长度现场确定,此拉杆作为模板的主受力点。4、为保证工期,+7.000m平台的施工采用昼夜进行施工。材料充足,设备充足且无故障。四、施工工艺挡土墙打孔植筋挡土墙

21、钢筋绑扎模板支设混凝土浇筑毛石混凝土砌筑平台、装载机通道地面浇筑+7.00m+10.00m剪力墙五、施工方法打孔植筋挡土墙钢筋与框架柱、地面的连接方式采用在原框架柱上打孔植筋,成孔方式采用水钻法,孔深180mm200mm,孔径16mm,植筋胶选用德国MKT牌植筋胶。成孔位置按照施工图纸要求在框架柱上弹出墨线,水钻固定方式采用膨胀螺丝固定,上部植筋孔施工时,搭设脚手架,铺设跳板作为施工人员的操作平台。在水钻打孔时保证水源,电源,劳动力充足。打孔完成后,利用鼓风机进行清孔,不能用水冲洗,保证孔内无灰尘、积水、杂物。植筋前对钢筋进行认真除锈,保证钢筋表面无锈斑。钢筋除锈完毕后,插入植筋孔内,用植筋注

22、射枪将胶液注入孔内,然后缓慢旋转钢筋,保证孔壁与钢筋之间的缝隙充满胶液并均匀。钢筋绑扎植筋验收合格后将挡土墙的竖向受力筋,水平向受力筋于植入地面,框架柱的钢筋进行焊接,焊接长度为5d(双面焊)。根据施工图纸,规范,图集要求对挡土墙钢筋进行制作,绑扎,确保焊接长度,搭接长度与间距。钢筋加工前需进行编制配料单,根据配料单备料。钢筋加工采用调直机调直、弯曲机、切断机切断弯曲成形,下料原则根据施工流水段下料搭配使用,达到最有利于节约的原则,避免单施工段下料成形,材料浪费;水平运输采用人工,垂直运输采用70T,25T。绑扎完毕经项目部质量员验收合格后进行隐蔽。模板支设本工程模板采用木模板,加固方式采用钢

23、管、木方、对拉螺杆。挡土墙模板支设前认真备料,每次备料数量为+3.500m以下的工程量,浇筑完后向上周转利用。支设模板按照施工图纸的几何尺寸,模板线严格进行,确保挡土墙的成型尺寸。由于受到挡土墙内侧毛石混凝土施工的限制,第一次模板的支设顶标高为+3.500m,加固牢靠进行挡土墙混凝土,内侧毛石混凝土浇筑,全部施工完成后进行+3.500m+7.000m挡土墙的模板支设与加固。为保证结构构件的成型尺寸,加固时对拉螺杆的布置间距全部控制在600左右,为保证对拉螺杆的节约在对拉螺杆套上pvc管。木方按照水平方向进行布置,间距200左右。钢管采用竖向布置,间距600两根。管道、设备平台的模板采用木模板,

24、加固采用钢管、木方,拉结钢筋拉结。为保证出渣平台的施工工期,在压滤楼+25.000m现浇板混凝土强度满足要求后立即进行满堂脚手架的全部拆除。即此管道、设备平台的模板加固利用原脚手架已不能实现。所以本部位的模板加固方式采用在原分化石斜坡上用水钻打孔植筋,孔径25mm,孔深800mm左右,孔位布置纵横向1000mm(约计105个植筋孔),打孔植筋按照上述植筋方式进行植25螺纹钢作为主受力点,外侧预留120mm,并带弯钩100mm长,在弯钩上焊接14钢筋作为拉杆(拉杆靠模版一端有丝扣100mm长)进行模板加固,保证拉杆的纵横向间距600mm左右。木方水平方向进行布置,间距200左右。钢管采用竖向布置

25、,间距600两根。分化石斜坡模板加固方式同管道、设备平台。另外由于分化石为斜坡,模板支设完成后,在混凝土振捣时,振动棒无法插入底部,所以在模板上水平,斜向均预留100*100洞口1000作为振动棒插入口,待混凝土浇筑至相应洞口同时振捣完成后木工立即进行此预留洞口的加固,保证满足上部混凝土的浇筑要求以及模板强度要求。混凝土浇筑挡土墙混凝土为C30,管道、设备平台、分化石斜坡混凝土为C20,全部采用现场搅拌,垂直运输采用70T,25T汽车吊,振动棒振捣。挡土墙混凝土浇筑时,为保证模板以及支撑系统的稳定与不变形,决定浇筑方式沿挡土墙均匀浇筑,每层浇筑高度达到1.500m左右时,进行另外一跨的浇筑,以

26、此循环进行,同时保证在上一层混凝土浇筑时下一层混凝土未达到初凝,振捣手在振捣过程中保证振捣棒插入下层深度为50mm80mm为适。管道,设备平台的混凝土浇筑时,水平运输用时风三轮车运输至+14.470m平台上自卸至浇筑部位,行进路线不平整者,采用200*300*1500枕木600铺设,上面铺设t=18mm厚钢板。由于本部位混凝土为大体积混凝土(浇筑几何尺寸:3.0*7.0*15.0),水泥水化热较大,在模板支设时沿水平向2000mm,竖向4000mm间距预埋100(L=1.50m)的pvc水平管作为散热孔。浇筑时每层浇筑高度控制在800mm左右,待初凝后在进行上一层混凝土的浇筑。分化石斜坡的混凝

27、土浇筑水平运输同管道、设备平台。每层浇筑高度控制在1.000m左右,保证均匀下料。浇筑混凝土前,应将模板底的杂物清理干净并用水冲洗同时保证不积水。混凝土分层浇筑振捣。针对本工程的垂直运输以及自拌混凝土的实际状况,同时保证在混凝土浇筑过程中不出现施工缝,所以要求混凝土浇筑前,查阅当地(万源,紫阳)天气预报,确保施工过程中不降雨,不停电。混凝土浇筑过程中连续施工,提前组织与安排充足的施工人员。同时检查机械与电气设备,将设备故障率降低为零。1)混凝土搅拌C30自拌混凝土配合比:水:195kg/m;水泥(42.5):375 kg/m;砂子:631 kg/m;石子:1171 kg/m。C20自拌混凝土配

28、合比:水:195kg/m;水泥(42.5):323 kg/m;砂子:710 kg/m;石子:1161 kg/m。在搅拌过程中,严格按照上述的配合比进行计量,保证混凝土的强度,和易性与塌落度。2)混凝土振捣振动棒振捣时确保不漏振,严禁超振,以反浆为准。振动棒距模板不得小于3cm,振动棒插入混凝土间距控制在150mm200mm,且采用快插满抽法。3)混凝土养护混凝土浇筑完毕后,劳务队安排专人进行养护。养护方式采用覆盖薄膜和浇水并进的方式进行,保证混凝土面处于湿润状态,养护时间不低于7天。4)质量要求所用部位混凝土浇筑完成后,保证振捣密实,不漏振,不超振,模板拆除后无蜂窝麻面。备注:在混凝土浇筑过程

29、中,必须安排木工进行实时实地看模以及支撑系统。对模板出现涨模,跑模的部位立即修理加固,保施工安全。毛石混凝土砌筑0.000m+6.800m之间毛石混凝土为C20毛石混凝土,工程量约计1890+149(装载机通道)=2039m3。为保证工期,此毛石混凝土采用三个阶段施工完成。第一阶段:+3.500m以下部分,同时在西侧两跨内预留10%坡道作为东侧三跨+3.500m以上毛石混凝土石料的垂直运输道路。第二阶段:东侧三跨+3.500m+6.800m部分,西侧坡道以及装载机通道,。第三阶段:西侧两跨内的运输坡道以及装载机通道部分。第一阶段+3.500m以下的毛石混凝土石料水平运输采用卡车,垂直运输采用挖

30、掘机,人工整平挖掘机运输的石料,混凝土垂直运输采用70T,25T吊车。人工在石料的整平时,保证石料水平向间距均匀(大约控制在50mm左右)横向每层的浇筑厚度控制在300mm,每层人工将石料整平质量员验收合格后,进行混凝土浇筑,保证每块石料间的缝隙混凝土为满灌且密实。按照上述进行以此施工直至施工全部完成。+7.000m平台地面、装载机运输通道地面混凝土浇筑+7.000m平台地面、装载机运输通道地面混凝土全部为C20耐酸耐磨自拌混凝土(无钢筋网片),厚度200mm,垂直运输采用70T,25T吊车。施工顺序:a:装载机运输通道施工。b:+7.000m平台地面施工。此施工顺序能够加快混凝土的浇筑速度,

31、加快工程进度。装载机通道地面砼浇筑顺序按照由高处向低处进行,原因为满足混凝土运输采用时风三轮车进行。混凝土上表面镶嵌25300(L=3.200m)防滑条,并保证振捣密实,表面平整。+7.000m平台地面混凝土浇筑顺序按照每跨进行,同时在浇筑下一跨时预留伸缩缝,伸缩缝内用沥青麻丝塞填密实。每跨浇筑时预先测设好混凝土上顶标高,保证振捣密实,表面平整(抹面时使表面向装载机通道方向成3%坡度)+7.00m+10.00m剪力墙本剪力墙施工工艺以及施工方法同挡土墙。备注:在挡土墙与上部剪力墙施工时,外排架采用双排架,双排架搭设要求纵横向竖杆间距为:纵向:1.00m,横向:1.30m, 水平向横杆步距:1.

32、55m,主节点处小横杆采用1.50m钢管,连墙件采用1.50m钢管3000mm在框架柱上固定连接。剪刀撑,密目网,架板按照规范进行布置。钢管,扣件选用合格者进行使用,保证扣件连接,紧固牢靠。四、施工安全目标确保无重大工伤事故,杜绝死亡事故,杜绝火灾,触电事故,轻伤频率控制在1以内。措施1)模板支设前,施工作业面处牢靠铺设木跳板或竹架板,严禁出现挑头板等不合理现象。2)所用高处施工人员穿防滑鞋,系安全带,戴安全帽。禁止心脏病,高血压,身体残疾,年长者,酗酒者进行高处作业。3)机械设备无故障,电气设备,电线电缆不漏电。4)施工人员禁止向下抛扔建筑材料,工器具。制度1)违反施工安全措施中1),3),

33、4)中任何一条者,要求施工作业队立即进行整改,处理。并处罚款每项1000元人民币;违反施工安全措施中2)中一项者,罚款处理:50元/人/次,并进行制止、整改。五、进度1植筋,挡土墙,管道、设备平台2012年10月1日2012年10月8日2植筋,分化石斜坡,毛石混凝土2012年10月9日2012年10月14日3植筋,地面,+7.000m+10.000m剪力墙2012年10月14日2012年10月20日4防腐2012年10月20日2012年10月23日Electricity lines, equipment inspections, found hidden in time for rectifi
