浅析桥梁工程钢桥面铺装施工工艺靳军安徽虹桥交通建设监理有限公司摘要:本文结合某工程实例对钢桥面铺装施工工艺措施进行探讨,以供参考。关键词:环氧沥青;铺装层;施工工艺0前言桥面铺装层主要作用是:防止车轮或履带直接磨耗行车道板;保护主梁免受雨水的侵蚀;并分布车轮的集中力。桥面铺装的质量直接影响到其使用功能的正常发挥,一方面桥面破损将造成跳车,影响行车舒适,降低运营服务水平;另一方面跳车产生冲击力加剧桥面铺装的破坏,严重时导致单板受力,降低工程耐久性,甚至导致桥梁破坏由桥面铺装层破坏而造成的桥梁结构的安全使用和耐久性问题已越来越受到工程界的关注。在目前工程建设中,钢桥桥面铺装施工由于其铺装层与梁板材料差异性较大,质量控制难度较大,下面结合某桥梁工程实例对钢桥面铺装施工工艺措施进行探讨,以供参考。1.1粘结层施工1.1.1材料(1)环氧沥青组分A是由双酚A和表氯醇经反应得到的液态双环氧树脂,不含稀释剂、软化剂和增塑剂,也不含无机填料、色素或其他污染物或不溶物质。(2)组分BId是一种由石油沥青和固化剂组成的均质合成物。不含不可溶物质(比如无机填料或色素等)和污染物。(3)环氧沥青粘结料钢桥面铺装防水粘结层与粘结层均采用环氧沥青作为粘结料,用作粘结料的环氧沥青由组分A与组分BId按配比在规定的温度条件下混合得到。1.1.2粘结层的喷洒(1)准备工作先用软扫帚或真空吸尘器清除桥面尘埃、杂物;如有油污,须用相应的油污清洗剂清洗(该清洗剂不得对钢桥面板的防腐涂装有损伤);最后用饮用水彻底冲洗干净(凸出桥面的结构物侧面也要清洗干净),对于桥面板防腐涂装已经损坏的地方,要采取必要的措施,重新进行防腐涂装。只有漆膜与钢板之间的附着力(按照ASTMD4541测试)大于5Mpa时才能开始环氧沥青粘结层的施工。(2)非喷洒区的覆盖为避免与铺装层接触的以外部位(如缘石和护栏座等)遭受污染,对这些部位在喷洒前采用塑料薄膜和粘胶带进行临时覆盖,施工完成后清理干净。环氧沥青粘结层洒布前桥面可用热鼓风机和专用烤灯烘干,确保桥面干燥,洒布时气温不低于10℃,风速适度;风速大于10m/s、有雾、露水、下雨或相对湿度大于90%时不得施工。施工前要确认施工期间不会出现雨、雾天气。(3)粘结料准备在拌和场分别将已预热过的A料和BId料由厂内储油罐泵入洒布机的相应储andmunicipalpartyCommitteesessionplenarysession,addingmeasures,promotetheXXeconomic,socialandculturaldevelopment.(A)theprimaryresponsibilityforfulfillingParty5yearsXXtownguidedbythe18thespiritoftheparty,conscientiouslyimplementtheCentraleightandthreeSunsandtenrequirementsoftheprovincial,cityandCounty,putthoughtandactionintoCounty,theCountyGovernmentamajordeployment,andtheCountydisciplineInspectionCommissionplenarysession.

②高程测量采用两级测量制,即一组测量,一组复核,确保数据准确无误。(2)非接触式平衡梁上层采用在摊铺机上安装非接触式平衡梁作为标高控制和找平基准的办法进行摊铺。下层、桥头伸缩缝和接缝处采用导梁引导控制厚度、平整度、高程。(3)沥青混合料拌和①沥青混合料用J-2000间歇式拌和机拌制,设有接料滑车。拌和站设在运输条件良好且排水设施齐全的位置;便于加强环境保护、消防和安全工作;场地分配设计协调合理,便于操作。②及时对所生产的沥青混合料进行试验、检验。a.正式拌和前先进行试拌,全面取样进行马歇尔稳定试验,检验温度、矿料级配及沥青含量的合格性,拌和好的混合料中的环氧沥青的含量要在其固化前用抽提法确定,如不符合应进行必要的调整。b.派专人检查沥青混合料质量,对于生产出的沥青混合料温度要每盘抽查一次,必须使所有集料颗粒全部裹复沥青结合料,并以沥青混合料拌和均匀为度;并目测每盘料质量,一旦发现花白料、焦料及温度不合格、离析等现象应立即废弃,直至合格为止。必要时停止拌和,找出原因并予以处理。c.每天结束后,用拌和楼打印的各料数量,以总量控制,以各仓用量及各仓级配计算平均施工级配、油石比与施工厚度和抽提结果进行校核。d.每天进行一次施工质量分析会,分析检测结果,计算油石比、各级筛孔通过量和沥青混凝土物理力学指标检测结果的标准差和变异系数,检验生产是否正常。(4)拌和机能分口、分级上料、计量准确、拌和均匀、自动调控自动记录。其生产能力为1.5~2吨每盘。并装有温度检测系统及二级除尘设备。(5)施工注意事项①贮油罐内环氧沥青各组分的预热在拌制环氧沥青混合料之前夜,要预先将A及Bv加热脱筒,分别泵入各自的厂内贮油罐中保温。②控制矿料加热温度根据试拌时确定的各冷料仓的流量向拌和机进料,经加热后进入热料仓,按生产配合比设计确定的各热料仓集料重量及石粉、矿粉的重量,投入拌缸,然后出料测温。这一工序一般约需重复3~5遍,直至出来的矿料温度稳定。③控制混合料出料温度当矿料温度稳定在规定范围内后,即可加入结合料进行混合料的拌和。按设计的油石比设定混合机的流量,并喷入拌缸中拌合均匀。将热混合料卸入临时热料斗(接料滑车)中,立即测温。当混合料温度满足规定范围后,即卸入运料车;运料车所装的环氧沥青混合料一般不超过7盘。④填写送料单、插入温度计将满足温度要求的混合料由临时接料斗中卸入运料车内的同时,将该盘料的温度记录在送料单上。一般情况下,一辆车装7盘料,装满后从车厢侧壁插入三andmunicipalpartyCommitteesessionplenarysession,addingmeasures,promotetheXXeconomic,socialandculturaldevelopment.(A)theprimaryresponsibilityforfulfillingParty5yearsXXtownguidedbythe18thespiritoftheparty,conscientiouslyimplementtheCentraleightandthreeSunsandtenrequirementsoftheprovincial,cityandCounty,putthoughtandactionintoCounty,theCountyGovernmentamajordeployment,andtheCountydisciplineInspectionCommissionplenarysession.

支金属杆插入式温度计(在运料车车厢的侧壁上留有插孔,这些小孔位于车厢底板以上30±5cm,距车厢两端各60±10cm以上及货舱中部的位置处)。送料单上还要填写第一盘料及最后一盘料的装料时刻。⑤材料的规格或配合比发生改变时,应重新根据室内试验结果进行试拌。试拌时必须抽样检查混合料的沥青含量、级配组成和相关物理力学指标,(6)环氧沥青混合料的运输①为防止混合料与运料车车厢粘着,凡车厢内与混合料接触的部位,涂一层专用的隔离剂。②运输车设有编号,并将编号贴于驾驶室前玻璃上和后挡板上。运料车轮胎胎面花纹要清晰,禁止使用光轮或磨耗严重的轮胎。③运料车用棉被及防雨蓬布覆盖,已经离析、结成团块或在运料车卸料后滞留于车上的混合料,以及低于规定铺筑温度或被雨水淋湿的混合料都予以废弃。④当料车中途因故停车,立即通知抢运人员组织抢运。⑤连续摊铺过程中,运料车在侧喂料机前10~30cm处停住,不得撞击侧喂料机。卸料过程中运料车应挂空档,靠摊铺机推动前进。⑥为防止摊铺机在钢桥面粘结层上打滑,可撒少许环氧沥青混合料。(7)环氧沥青混合料摊铺①环氧沥青混合料摊铺采用德国产ABG423摊铺机摊铺,具有可加热的振动熨平板及振动夯等初步压实、熨平装置。摊铺机每天摊铺工作前1小时进行预热。②上层采用非接触式平衡梁(SAS系统)控制厚度与平整度,下层则采取挂线的方式。当紧靠先前摊铺过的铺装层摊铺时,靠近已完成铺装层的熨平板端部设一个滑雪传感器控制,该传感器能够感应先前铺装层的坡度并控制新铺装层的坡度在先前铺装层的坡度±1.5㎜的误差范围内。离先前铺装层远的熨平板端部用非接触式均衡量控制,要保证铺装层的横坡度一致。③摊铺宽度及纵缝中央分隔带两侧各分三幅摊铺,各设两道纵缝。每幅铺装层的设计宽度及纵缝位置严格按照施工图设计要求。④摊铺速度设专人计算并控制摊铺速度,根据供料能力及各料车送料单的“容许卸料时间范围”进行及时调整,以控制不停机、不超时、力求匀速摊铺为原则。⑤摊铺方向及顺序摊铺方向及顺序的设置应能保证摊铺的顺利进行,并尽可能的减少料车及机械在已铺环氧沥青面层上行驶。⑥料车调度运料车将混合料运至前场后停在料车等待区(标示牌的区域)。司机将送料单交与前场测温员。前场测温员通过对讲机报告前场料车调度员。调度员确定每一料车的具体卸料时刻和卸完时刻,并通知摊铺机管理员。由摊铺机管理员确定摊铺机的行进速度。andmunicipalpartyCommitteesessionplenarysession,addingmeasures,promotetheXXeconomic,socialandculturaldevelopment.(A)theprimaryresponsibilityforfulfillingParty5yearsXXtownguidedbythe18thespiritoftheparty,conscientiouslyimplementtheCentraleightandthreeSunsandtenrequirementsoftheprovincial,cityandCounty,putthoughtandactionintoCounty,theCountyGovernmentamajordeployment,andtheCountydisciplineInspectionCommissionplenarysession.

⑦注意松铺厚度及路拱中途少做变动,必要时加以调整,务求平顺,以求不影响平整度。并且螺旋布料器中的料位以略高于螺旋布料器2/3为宜,避免摊铺层出现离析。机械摊铺过程中,不用人工反复修整,但当出现以下问题时:断面不符合要求、局部缺料、局部混合料明显离析、表面明显不平整、死料等,在施工技术人员专门指导下认真调整、局部换料,仔细修补,同已铺混合料接顺,不留明显印迹和差异。在摊铺过程中产生的废料、“死料”应集中放在小推车中,然后集中清理出施工现场。⑧摊铺如果突然遇雨,立即停止施工,并清除未压实成型的混合料,未铺料必须全部予以废弃。(8)环氧沥青混合料碾压①环氧沥青混合料的碾压采用如下配套的碾压机具:13t双钢轮压路机2台,25t胶轮压路机2台。②碾压应紧跟摊铺机。碾压过程按初压、复压、终压三个阶段进行。③碾压时压路机驱动轮面向摊铺机,由低到高,依次连续均匀碾压,相邻碾压带重叠1/3轮宽,碾压过程中压路机不得在铺装层上转向、调头,压路机起动、停止必须减速缓行,不准紧急刹车制动。④要对初压、复压、终压段落设置明显标志,便于司机辨认。对碾压顺序、压路机组合、碾压遍数、碾压速度及碾压温度应设专岗管理和检查、记录,坚决杜绝面层漏压。当表面温度不满足要求时,用插入式温度计测记内部温度。当内部温度不满足要求时,除多压两遍外,要查明原因,采取有效措施,并杜绝再次发生。⑤对于压路机碾压不到的局部位置(如落水口与缘石之间),采用人工夯或手扶式振动夯等小型机具,将压路机不便压实的地方振捣密实。(9)接缝处理①施工缝位置a.纵向施工缝位置严格按照要求进行施工。b.尽量避免横向施工缝。当因故无法避免时,横向施工缝位置必须依据结构图纸来确定,且相邻两幅及上、下面层的横缝要错开1m左右。②施工缝的切割a.环氧沥青混凝土铺装下层的纵、横施工缝均采用斜接缝。b.切缝前要预先画好线,沿线切割。c.采用手持式切缝机进行切割。d.切割时间要通过试切确定。e.铺装层下层切缝深度控制在1.5cm左右,上层切缝深度控制在2.0cm左右。f.切缝后,将铺装多余的部分撬走,并清除干净。(10)养护环氧沥青混凝土铺装施工完毕后需进行养护,采用自然养护方式,且养护期不少于30天,在此期间禁止一切车辆通行。摊铺完成后若铺装出现“鼓包”,可andmunicipalpartyCommitteesessionplenarysession,addingmeasures,promotetheXXeconomic,socialandculturaldevelopment.(A)theprimaryresponsibilityforfulfillingParty5yearsXXtownguidedbythe18thespiritoftheparty,conscientiouslyimplementtheCentraleightandthreeSunsandtenrequirementsoftheprovincial,cityandCounty,putthoughtandactionintoCounty,theCountyGovernmentamajordeployment,andtheCountydisciplineInspectionCommissionplenarysession.

采取如下方法加以处理:环氧沥青混合料铺装碾压完毕,在3~5天内,派专人24小时不断地检查是否有“鼓包”发生。当发现“鼓包”时,立即用钢针由包顶插入放气。在3天内发现的,放气后用手持木夯锤将“鼓包”击平,并用环氧胶填满插孔。若3天后发现的,放气后必须用兽用注射器将现配环氧沥青胶注入“鼓包”内,击平后让多余的环氧胶由插孔冒出并刮平。参考文献[1]吕红军,桥面铺装病害的产生及预防,《科技情报开发与经济》2005,1[2]孟飞,浅谈沥青混凝土铺装层的施工技术,《山西交通科技》2004.11.增刊andmunicipalpartyCommitteesessionplenarysession,addingmeasures,promotetheXXeconomic,socialandculturaldevelopment.(A)theprimaryresponsibilityforfulfillingParty5yearsXXtownguidedbythe18thespiritoftheparty,conscientiouslyimplementtheCentraleightandthreeSunsandtenrequirementsoftheprovincial,cityandCounty,putthoughtandactionintoCounty,theCountyGovernmentamajordeployment,andtheCountydisciplineInspectionCommissionplenarysession.
