18、杂，不得有氧化铁皮和油迹，允许有少许铁锈和回火色，钢筋进入工地要进行钢筋的机械性能试验，其直径和各种尺寸应符合规范要求。2、钢筋应尽快存入仓库或料棚，如不可能也要选择干燥场地露天堆放，钢筋上加彩条布覆盖，下放垫木，离地不少于20厘米，四周挖排水沟，钢筋要按不同等级、牌号、顺号、炉号、直径、长度分批挂牌堆放，并标明数量，不能混淆，钢筋不能和酸、盐、油这些物品在一起存放，也不要靠近有害气体的车间。6.2.1.2、钢筋的加工及安装1、钢筋的矫直。矫直粗钢筋一般受设备条件的限制，因此人工矫直粗钢筋，是当前的常用方法。首先将钢筋弯曲处放在板柱间，用平头横口扳子将弯曲处基本扳直，然后用平直锤拍平，如无平直
19、锤，也可用大锤在工作台上慢慢拍平，直至钢筋在工作台上可以滚动为合格。2、钢筋的除锈。钢筋的表面要清洁，油渣、漆污和用锤敲击时所剥落的污皮、铁锈等要清除干净。特别是铁锈、水锈要清除干净。3、钢筋切断。钢筋切断采用钢筋切断机，其作业方法及注意事项如下：在使用前，先根据钢筋的粗细调整刀片位置，其平面间隙以0.5-1.0毫米为宜。刀片要安装正确、牢固、润滑油要加足，经空车试验正常，尚能进行操作。要在活动刀片后退时进料，不要在前进时进料，以免发生事故，断切短料要用钳子夹住操作，不能直接用手，机身上铁末、锯屑，要用毛刷清扫，不要用手抹、嘴吹。钢筋加工全长长度偏差不大于10mm。4、钢筋弯曲。首先，根据钢筋
20、设计图进行画线和选料，对于钢筋直径小于10mm采用人工弯曲，直径大于10mm时，宜采用弯曲机进行加工，钢筋弯曲严格按照规范要求，弯起钢筋的弯起位置偏差不大于15mm。5、钢筋绑扎。按设计位置布好箍筋并绑扎于主筋上，箍筋要与主筋垂直。箍筋转角与主筋（或架立筋）的交接点均应绑扎，但箍筋的平直部分和主筋的相交点可间隔交错绑扎成梅花形式。箍筋弯钩的叠合处，四角错开绑扎，不要集中在一根主筋上。钢筋骨架的外形尺寸必须正确，其两相邻绑扎点互成八字形，以防止骨架歪斜变形。6.2.2、模板采用四套定型扣模，模板长度为1.9m，截面尺寸为10cm10cm，在预埋铁钩处设置预埋孔。6.2.3、混凝土施工6.2.3.
21、1、混凝土拌和1、根据混凝土施工配合比设计确定C20配合比为：水泥336：砂690.8：碎石1228.2：水195。2、混凝土拌和前，对砂、石进行检测，据以调整骨料和水的用量，计算出施工配合比。开盘前对计量设备进行重点校核。计量和配水装置，精确度准确到0.4%，材料均按质量称量，水、水泥称量允许偏差为1%，细、粗集料称量允许偏差为2%。3、混凝土拌和时间不低于1.5分钟，拌和物应拌和均匀，颜色一致，不得出现离析和泌水现象。在拌和机卸料过程中，从卸料流的1/4和3/4之间部位采集试样，进行试验，检查其均匀性。4、混凝土拌和物的坍落度，每一工作班或每一单元结构物不小于2次，如不符合要求，及时进行调
22、整。6.2.3.2、混凝土浇筑1、浇筑前检查施工组织，包括人力、器材、机具设备等的配备情况。检查模板、钢筋，包括模板结构尺寸、钢筋数量、规格、位置、除锈以及是否牢固可靠，不致发生变形移位等情况。2、清除模板内积水和泥污木屑等杂物。模板如有缝隙，应填塞严密，模板内面应涂刷脱模机。3、采用手推车将混凝土运输至振动台。人工将混凝土铲入模板内，在振动台上振动，待混凝土停止下沉，不再冒出气泡，表面呈现平坦、泛浆时停止振动。表面及时进行修整、抹平。4、混凝土振动完成后即脱模，将立柱整体反扣在预制台座上。脱模时应轻拿轻放。5、养生。混凝土浇筑完毕1012小时以内，就要加以覆盖并浇水。养生期为714天。6.3
23、、立柱安装6.3.1、立柱的检验及运输立柱在运到工地之前，应首先向监理工程师提交每一种柱子的试样。监理工程师将检查其外观质量，并检验几何尺寸和混凝土的强度要求。钢筋混凝土立柱的运输及装卸应避免立柱拆断或摔坏棱角，装车时码高不宜超过五层。6.3.2、施工放样按公路用地界范围内30cm处进行施工放样。先定中心线，然后按设计的柱距定出柱位。确定桩位时应与公路界地形相协调，可以做成斜坡形，也可以做成阶梯形。在低洼地区，当地面纵剖面发生突变，无法保持规定的离地净高时，可使用较长的立柱，然后拉上多股带刺铁丝。带刺铁丝之间的垂直净空不大于150mm。如起伏过大，可考虑对地形进行一定的整修，尽可能使隔离设施起
24、伏自然，避免局部地段的突然变化。一行隔离栅中如有断开处或在道路交叉口时，可视需要适当调整立柱间距。公路两侧的封闭，一般在桥梁、通道等处为薄弱环节，人、畜等往往会从桥头锥坡处钻入。因此，在这些地点，需下功夫把隔离栅围死。对一些流水量很小的涵洞，隔离设施也可以考虑直接跨过。但在跨沟的地方，也需作一定的围封处理，以防人、畜随意钻入公路内。6.3.3、柱孔的开挖柱孔深度应符合设计要求，挖钻到设计要求深度后，应将基底清净，经检验合格后，方准进行下道工序。6.3.4、立柱的埋设立柱埋设应分段进行，先埋两端的立柱，然后拉线埋设中间立柱。立柱纵向应在一条直线上，不得出现参差不齐的现象。柱顶应平顺，不得出现高低
25、不平的情况。放入立柱后，用临时支撑固定立柱，检查立柱的标高、垂直度和线形之后，进行C20混凝土浇注，浇注的混凝土应分层捣实。在混凝土养生7d期间，不应在立柱、拉索和支撑上安装或拉紧任何材料或部件6.4、刺铁丝的安装立柱基础混凝土强度达到设计强度70%以后，方可安装刺铁丝。刺铁丝安装时要求从端头立柱开始。刺铁丝之间要求平行、平直，刺间距为10cm。先将刺铁丝用立柱上预埋的挂钩挂住，绷紧后将挂钩弯钩拗死封口固定刺铁丝。横向与斜向刺铁丝相交处用12号铁丝绑扎。在高压输电线穿越过安装隔离栅的地方，隔离栅应按电力部门的规定接上地线。当电线平行或接近平行于隔离栅且电线在隔离栅上方时，应在每端或按不大于40
26、0m的间距埋设地线，接地电阻值小于10（欧姆）。6.5、隔离栅安装完毕，立柱基础均需进行最后压实处理。七、施工质量管理和质量检验7.1、施工质量管理7.1.1、加强质量宣传，树立质量观念加强全体职工的质量意识，树立“质量第一”的观点，并在全体职工中牢固树立起“创优在我心中，质量在我手中”的信念。7.1.2、建立施工全过程质量控制制度1、按照质量保证体系落实质检仪器和人员，对施工各阶段的各项质量指标应做到及时检查、控制和评定，以达到所规定的标准，确保施工质量及其稳定性。2、施工质量的控制、管理和检查应贯穿整个施工过程，应对每个施工环节严格控制把关，对出现的问题，立即进行纠正直至停工整顿。3、应完
27、善施工准备、试验和施工过程中的各项技术指标的检验，出现施工技术问题的报告、论证和解决等，做到施工全过程的质量动态检测、控制和管理。4、加强施工报验。（1）原材料检验包括外观检查、尺寸检查、钢材的抗拉强度、屈服强度、延伸率和镀锌层厚度测试。以同一批号的每批钢材为取样单位，对钢材的强度进行检查。刺铁丝用的钢丝，宜采用低碳钢丝，并应符合一般用途低碳钢丝（GB34382）的规定。刺铁丝网规格及防腐处理均应满足图纸要求，具有产品合格证并经工地检验后方可使用。刺铁丝表面不得有锈蚀、擦伤、折叠。（2）施工报验立柱在运到工地之前，应首先向监理工程师提交每一种柱子的试样。监理工程师将检查其外观质量，并按公路工程
28、质量检验评定标准（JTG F80/1-2004）检验几何尺寸和混凝土的强度要求。立柱基坑开挖好后应报监理工程师验收。安装刺铁丝前，应报监理工程师对立柱基础强度、立柱垂直度和柱间距进行验收。7.2、质量检验安装完成的隔离栅，应以2km为一检验验收单位，连续取10跨隔离栅进行检查验收，或以通道间长度为一验收单位，至少连续检查5跨。7.2.1、质量检验基本要求包括：1、立柱和基础的几何尺寸和强度不小于设计图纸规定。2、检验刺铁丝的安装高度和绷紧固定程度，每根刺铁丝的中心垂直度不得大于15mm。3、立柱埋深应符合图纸要求。立柱与基础、隔离栅与立柱之间的连接应稳固。4、隔离栅起终点应符合图纸对端头封围的
29、要求。7.2.2、质量检验实测项目：隔离栅检查实测项目项次检查项目规定值或允许偏差检查方法1柱顶高度(mm)15直尺：每100根测两根2立柱埋深符合设计直尺：过程检查，抽检10%3立柱中距(mm)30拉尺：每100根测两根4混凝土强度(MPa)在合格标准内按JTG F80/1-2004附录D检查5立柱竖直度(mm/m)8直尺，垂线：每100根测两根6隔离栅顺直度(mm/m)8拉线、塞尺：抽检2 八、安全生产及施工环保8.1、安全生产 8.1.1、建立并落实安全生产责任制对员工进行安全生产教育，树立安全第一的思想，落实安全生产责任制度。贯彻专业检查与群众检查相结合的方针，施工现场设专职安全员做到
