12、为陕西安康公路发展项目安康至毛坝高速公路土建工程,JL7驻地办管辖项目位于大坝山区,线路沿任河河谷布设,为典型的“沿溪线”工程,变短主要工程有连拱隧道1座长317米;特大桥5座长10531.03米;大桥4座长1654.92米;中桥2座258.24米;变异Y型互通式立交1座桥长1926.998米,共计桥梁单幅长14371.188米,路基2613.5米,因此桥梁监理工作是难点和主导工程。项目共有承台、系梁20768.11M3683个,根据地形和水文条件不同,河道内分别采用土围堰、土袋围堰、钢板桩围堰、钢筋混凝土板桩围堰、套箱围堰等施工工艺。2、地形、地质与地貌线路位于任河河谷,何故为U形谷,河谷两

13、侧山势陡峻。山体自然坡度25-50度,工程地质主要以板状泥灰岩、灰岩为主,局部为变质软岩夹硬质砂岩,地表岩石风化严重;任河河床中沉积有2-20米厚砂砾石、卵石强度较低;沿线不良地质主要有滑坡、崩塌和构造物破碎带多,其中该小型滑坡崩塌较为发育,地质构造物较为复杂。3、水文气象沿线地下水比较发育,类型主要有第四条松散层孔隙潜水和基岩裂隙水,水量比较丰富,水质属矿化度软质水,适宜生产用水和生活用水,对混凝土无腐蚀性;项目所辖区段年降雨主要集中在7、8、9月份,年初降雨量1130-1260mm,年均气温15,极端最低气温-7.6、极端最高气温42.3,项目沿线河流主要为任河,洪水期主要出现在7、8、9

14、月份,水量充沛,水位变化大且迅速,项目上游有一小水库,毛坝水库,水库蓄洪防洪能力不明显,主要用于蓄水发电,基本每天进行泄洪发电,造成任河水位变化,给施工增加难度。三、施工准备阶段的监理1、熟悉合同文件对合同文件中存在的差、错、遗漏、含糊不清等问题应查证清楚,提出合理的处理办法报管理处、总监办。2、检查施工所有材料、试验监理人员进行平行试验,并做好混凝土配合比设计试验。3、现场设备是否齐全、完好、并有一定数量的备用设备。4、测量工程师对承台、系梁的放样进行复核、复测。5、见检查承包人质量保证体系。6、审查承包人的施工机械设备。7、审查承包人的进场材料。8、审查承包人所报的施工组织设计。9、审查承

16、计和施工技术方案提出初审意见,报驻地监理工程师批准是否开工。材料控制凡进场使用的所有材料必须符合有关材料的标准和要求,材料在使用前,监理人员应要求承包人出具自检合格的报告。凡未自检或未自检抽检不合格的材料,一律不得使用。监理工程师要按规定的频率进行抽检,发现有异常情况时,应加大抽检频率。有关材料的技术标准及施工要求,。详见相关技术标准;现场控制详见管理处,总监办下发管理办法及实施细则。场地要求材料场地必须经硬化处理,砂石材料必须分开堆放不得混堆;水泥场地必须架空离地30CM以上,并具有完备的防雨、防潮设施;钢材的原材和半成品,成品骨架应架空离地,不得直接放置在地面上;现场临时蓄水池应做硬化处理

17、,确保施工用水清洁无杂质。施工现场应井然有序,妥善布置,必须竖牌标明材料来源,规格,施工配合比及各施工工序负责人及材料受检状态做到文明施工,合理组织,达不到要求的不得开工,并通知承包人立即整改。机械设备控制进场设备必须性能良好部件齐全,设施配套,能满足连续施工及规范的要求,所有设备均须经监理人员验收合格后方可使用。施工现场的搅拌机,电源及振捣器等关键设备都必须有备用品,确保施工能连续进行。当机械设备的数量和质量不能满足施工连续性的要求时则不能开工。现场施工备料是否足够,混凝土配合比设计报告是否完成,是否能按照施工组织设计要求进行合理有序的施工。桩基础施工全部完成,应按设计要求挖完土,完善桩基施

18、工验收记录。根据地质情况定出放坡率,根据基坑尺寸、深度、水位情况确定基坑开挖尺寸,并准备好排水设备。采用人工开挖基坑,开挖时视现场地质情况控制边坡坡度,注意边坡稳定,挖至设计标高后在基坑底四周设30cm30cm排水沟和60cm60cm积水井,以便及时排走基坑积水,确保基底不被水浸泡,基坑挖好后应进行全面的检验,平面位置准确、断面尺寸符合设计及规范,基坑标高为50mm。修整桩顶混凝土:采用风镐破桩头,不得冲击钢筋,预留10cm,采用人工沿桩基外侧向内凿除,桩顶疏松混凝土全部凿完,如桩顶低于设计标高时,桩头顶面凿成水平面,大面平整无松动砼块、残渣。须用高出一个等级混凝土接至设计桩顶标高,在达到桩强

19、度的50%以上,再将埋入承台、系梁内的桩顶部分凿毛、冲净。如桩顶高于设计标高时,应预先剔凿。桩顶深入承台中的钢筋长度为120cm,钢筋在越过桩头时不得截断。应将基底虚土、杂物等垃圾清除干净,在表面铺一层2-3cm厚的水泥砂浆或小石子砼。2、钢筋质量检查进场时,钢筋应有质量证明书,试验报告单,钢筋表面每捆(盘)钢筋均应标有诸如规格、型号、厂家、生产、日期、钢号、生产罐等的标志牌。验收按炉罐(批)号及直径分批检验,并应按现行有关国家标准的规定抽取试件作力学性能试验,经验收合格后方可使用,钢筋堆放要挂牌分类堆放。钢筋表面必须清洁,对锈蚀严重的钢筋,经除锈后方可使用。质量要求序号项 目允许偏差(mm)

20、检查方法1受力钢筋间距20尺量:每构件检查 2个断面2箍筋、横向水平钢筋、螺旋筋间距10尺量:每构件检查5-10个问题3弯起钢筋位置20尺量:每骨架抽查30%4钢筋保护层厚度20尺量:每构件沿模板周过边检查8处3、钢筋制作及安装:核对钢筋半成品:应先按设计图纸核对加工的半成品钢筋,对其规格、形状、型号、品种经过检验,然后挂牌堆放放好。各种编号钢筋应按设计尺寸下料、制作成型。钢筋绑扎及焊接:钢筋应按顺序绑扎,一般情况下,先长轴后短轴,由一端向另一端依次进行,操作时按图纸要求划线、绑扎、最后成型,焊接长度、宽度、平整度应符合要求,焊接饱满无夹渣,气泡。绑橡胶垫块:底部钢筋下的橡胶垫块,厚度50mm

21、、间隔1m,应与钢筋绑穿,不应遗漏,垫块应相互错开,分散布置不应遗漏。4、模板检查承台模板要求选用大块钢模板,模板每块面积不小于31,采集模板应考虑与柱模板的整体性。支架必须具有足够的强度,刚度和稳定性,其支架的支撑部分有足够的支撑面积。模板安装在基土上,基土必须坚实平整。模板接缝应严密、平整。模板与混凝土的接触面应清理干净,并采取优质脱模剂刷均匀,模板安装必须经过监理工程师验收合格后方可进入下一工序施工。质量要求序号项 目允许偏差(mm)检验方法1尺寸30尺量:长、宽、高检查各2点2顶面高程20水准仪:检查5处3轴线偏位15全站仪或经纬仪:纵、横各检查2点5、模板安装检查应采用1.0m、1.

22、5m钢模板拼装,周边用建筑钢管加固调直模板,螺栓对拉加固,确保模板间连接紧密。混凝土浇筑不漏浆,在交叉点处使用支撑于坑壁上。模板安装时,应边安装边校正其垂直度,在接缝处夹海绵条。模板安装完成后,检查平面位置、模板各部位尺寸,顶面高程,模板表面平整度和板缝间的错台等。在模板调整校正符合要求后,检查加固措施是否满足要求,然后将模板内部和表面油污、杂物清除干净,并在模板面上涂刷脱模剂,在灌注混凝土前将桩顶混凝土表面清理干净,并用水冲洗湿润,但不得有积水。按图纸要求预埋墩柱钢筋,在砼浇筑过程中防止变形。6、混凝土浇筑检查混凝土用罐车运送到施工现场,由现场实验人员进行坍落度,均匀性检查,经检验合格后方可

23、进行混凝土浇筑,混凝土坍落度要求在12cm-16cm之间(泵送),浇筑前应清除模板内的杂物,特别是桩顶位置,要清扫干净保证新旧混凝土的良好接合。浇筑从一侧往另一侧进行,浇筑分层进行,每层厚度不超过30cm,混凝土自由下落高度须小于2m,否则应采取措施,防止混凝土下落过程中出现离析现象。每层混凝土振捣时,振捣棒不能直接碰撞模板、钢筋振捣棒移动间距,最大不能超过其作业半径的1.5倍,对每个振动部位,必须振动到该部位混凝土密实为准,密实的标志是混凝土停止下沉,不再冒气泡,表面呈现平坦、泛浆;上层混凝土在下层混凝土初凝前完成,振捣作业防止出现混凝土漏振或过振现象。浇筑至顶面时应注意收浆、整平工作,保证

24、顶面平整美观,并在混凝土初凝后,立即进行覆盖养生,防止混凝土表面出现收缩裂缝。7、成品保护安装模板和浇筑混凝土时,应注意保护钢筋不得直接攀踩钢筋。钢筋的混凝土保护层厚度应符合设计及规范要求,其橡胶垫块布置不得遗漏。混凝土达到1.2MPa前不得踩踏或安装模板。拆模时要通过砼强度试验结果确定,要避免重撬、硬砸,以免损伤混凝土和钢模板。五、必须注意的质量问题蜂窝、露筋:由于模板拼装不严,混凝土漏浆造成蜂窝;振捣不按工艺操作,造成振捣不密实而露筋。搅拌不均匀或拆模过早,养护不够,都会导致混凝土棱角损伤。偏差过大:模板支撑、卡子间距过大或不牢固;混凝土局部浇筑过高或振捣时间过长,都会造成混凝土胀肚、错台

25、、倾斜等缺陷。避免振捣棒或运料车碰撞钢筋,致使钢筋位移。六、质量记录钢筋的出厂证明和合格证,以及钢筋试验报告,每一批进场钢筋必须有出厂质量证明书和试验报告单。每60T为一批进行钢筋原材料试验。钢筋隐蔽验收记录。模板标高、尺寸的预检记录。七、安全注意事项施工现场必须配备一个标准的配电箱,配电箱上要有锁,还要有一个专业电工,所有接线一律找电工操作,不得私自接线。在露天作业时必须加盖防雨设施以防受潮。作业结束后必须切断电源,收好电线。八、其他未尽事宜或不妥之处参阅招标文件,技术规范、图纸。further clarify the transformational development, XI Jin
