材料要求进场水泥、砂石料、钢筋、外加剂等原材料均应送相应资质的试验室进行检定，满足规范要求后方能使用，否则必须清退出场。水泥、钢筋等还应有出厂合格证。第四章施工部署4.1 清水河 4 号大桥人员配备组长:杨福生副组长：严盛、崔海龙组员：张雷、杜国祥、郝延明、刘哲、李敬学、孟博、张智义领导小组岗位职责：杨福生：全面负责组织施工管理工作及施工队伍落实；文档编码:CS5V5Z3A9O6

桥面施工放样施工放养前应先将基层清理干净，以桥中轴线为基准，放出行车道的宽度和防撞墙或人行道以及栏坐的位置。桥面铺装层施工时要控制好铺装层的标高。5.2 钢筋绑扎桥面铺装所用的钢筋，在钢筋加工场按图纸要求加工成型；使用时运至施工现场，按设计要求进行绑扎，绑扎过程中应调整好钢筋间距，钢筋网片绑扎成型后，按要求垫设保护层，并不得随意踩踏钢筋网片。5.3 模板支护模板支护采用在已吊装好的梁于梁之间架立脚手架用于支撑桥面板以下的模板。路中心线主幅路的两座桥只有一个沉降缝相隔，所以中线的悬空部位也可与梁中间部分同样的施工方法。处于主幅路外边侧的悬空部分可以在预制梁的同时设置预留孔预留孔内插入钢筋外部与钢管固定钢管垂直梁和水平梁放置并加以斜支撑固定，形成一个固定三角支架三角架的间距可定为1 米一个。然后进行每跨两头模板的封堵，支设好的模板应具有一定的刚度，以防浇筑时混凝土的测压力使模板变形或跑模。5.4 混凝土浇筑工程施工前，由具有相应资质的试验室出具混凝土配比单。施工时再由工地试验室调整到适合现场的配合比进行施工。混凝土由搅拌站系统拌制，混凝土搅拌运输车运至浇筑点，由混凝土汽车泵进行浇注，按测量放线的高程找平混凝土面层，浇筑时应注意尽量不要踩踏钢筋。5.5 混凝土养护根据施工对象、环境、水泥品种、外加剂以及混凝土性能的不同采用不同的养护方案，各类混凝土结构的养护措施及养护时间遵守公路砼强度检验评定标文档编码:CS5V5Z3A9O6 HL5N5R1Y9C5 ZO4H2O9U8A3文档编码:CS5V5Z3A9O6 HL5N5R1Y9C5 ZO4H2O9U8A3文档编码:CS5V5Z3A9O6 HL5N5R1Y9C5

ZO4H2O9U8A3五盂高速公路LJ3 合同段清水河4 号桥桥面铺装施工方案7准规定。当新浇结构物与流动水接触时，采取防水措施，保证混凝土在规定的养护期之内不受水的冲刷。拆模后的混凝土立即使用保温保湿的无纺土工布覆盖，外贴隔水塑料薄膜，使用自动喷水系统和喷雾器，不间断养护，避免形成干湿循环，养护时间不少于7d 后，拆除养生毯，再用塑料薄膜紧密覆盖，保湿养护14d 以上。养护期间混凝土强度未达到规定强度之前，不得承受外荷载。5.6 施工缝处理混凝土构件应尽量一次浇筑完成，施工前必须做好停水、停电的应急措施，尽量避免由施工原因造成在混凝土浇筑过程中出现施工缝，当不可避免施工缝时，按规范要求进入混凝土施工缝处理程序。施工缝处理按公路工程桥涵施工规范等相关规定进行，当施工缝处于水平状时，浇筑上层混凝土前应首先浇筑50100mm 厚的水泥砂浆，以提高接缝处混凝土的密实性。第六章桥面铺装施工各项安全措施及安全注意事项6.1 砼泵送设备的主要安全措施桥面铺装主要使用混凝土汽车泵输送混凝土，其安全措施如下：1、泵操作工必须是经培训合格的有证人员，严禁无证操作。2、泵管的质量应符合要求，对已经磨损严重及局部穿孔现象的泵管不准使用，以防爆管伤人。3、泵管架设的支架要牢固，转弯处必须设置井字式固定架。泵管转弯宜缓，接头密封要严。4、混凝土泵料斗内的砼保持一定的高度，防止吸入空气造成堵管或管中气锤声和造成管尾甩伤人的现象。5、混凝土泵的安全阀必须完好，泵送时先试送，注意观察泵的液压表和各部位工作正常后加大行程。在砼坍落度较小和开始起动时使用短行程。检修时必须卸压后进行。文档编码:CS5V5Z3A9O6
