15、工难度加快安装速度无焊接安装前言茅山500kv变电站位于金坛市经济开发区三村东柘荡,所址总用地面积约7.9万m2,本期升压部分用地面积4.1万m2。主变压器:新安装2台1000mva/500kv主变压器;500kv出线:500kv出线2回,远景出线8回。工程管理目标:达标投产并达到国家电网公司优质工程标准(2009版)国家电网公司优质工程,实现零缺陷移交运行;确保扬子杯、争创鲁班奖,确保江苏省文明工地争创国家电网公司流动红旗,实现精品工程。但是工期从开工到投运只有八个月,其中电缆沟支架安装就有7932副。安装要求高,工期非常紧。按照业主要求电缆沟浇筑完成后必须在20天内安装完成7932副电缆沟

16、支架,由江苏省送变电安装公司进行穿电缆工序,而根据现场工程量及传统经验,如果采用传统电缆支架安装方法,难以完成此项任务。一、问题的提出传统电缆沟支架安装存在问题:1.支架为现场焊接,对焊工要求高。不仅要求焊接工艺好,而且对焊缝周边处理必须细致到位,方可满足创优要求。2.投入人力多;本工程至少需要投入30个焊工。3.工序繁琐,安装周期长。需要处理后续的焊渣,焊缝周边还需要彻底处理干净后涂两遍环氧富硒锌漆、一遍银粉漆进行防腐处理。根据现场施工量及传统经验,安装周期需要30天才能完成。4.外观不美观,由于对支架焊缝进行了防腐处理,支架焊缝周边与其它区域产生色差。成本大。需投入较多多人力、物力。5.成

17、本大。需投入较多多人力、物力。二、分析问题电缆沟支架安装工作量大,质量和安全文明施工要求高,传统施工方法,控制环节多,难度大;安装速度慢,无法满足业主对工期和文明施工的要求。如何加快施工速度,确保工程质量,按期完工及优化文明施工成为我们必须解决的课题。解决上述问题,须进行安装工艺改进,甚至创新,实现电缆沟支架无焊接安装,降低施工难度,加快安装速度,成为我们确保工期和质量的关注焦点。三、提出方案、确定方案经过建设单位设计单位和施工单位的共同研究和讨论,并根据所选的课题,认真思考,进行反复研究和构思,确定思路:改变以往传统电缆沟支架焊接安装方法。(电缆沟支架焊接在扁铁上,然后对焊接后被破坏的镀锌层

18、进行二次镀锌)。充分利用好预埋件及其连接的接地扁铁,安装电缆沟支架时实现无焊接安装,节约现场焊接时间和费用。现将总结得出如下几种方案:方案提出表方案方案详细说明建议人方案1预埋螺栓,校核固定,电缆沟支架固定在螺栓上。李强方案2在电缆沟的侧壁钻孔安装螺栓,校核后化学浆固定支架。吴鹏方案3安装带螺帽的扁铁,然后采用螺栓连接电缆沟支架,支架设置长圆可调节孔。乔永洁“电缆沟支架无焊接安装”最佳方案分析评价表类型技术特点评估方案结论安装工期操作难易安装费用效果确定对其他影响方案一校核固定周期长,施工操作繁琐,现场安装精度不易调节53副/(d*人)*8人=424副/d7932副/424=19天螺栓需要精确

19、预埋,操作较难9元/副预埋偏差难以调整影响砌筑工效不选方案二支架安装可调空间小,安装就位时间长,速度慢。50副/(d*人)*8人=400副/d7932副/400=20天采用化学浆,操作较难13元/副安装准确灌浆后需要等到一定强度后才可进行下道工序,时间较长不选方案三操作简单,能调节预埋件安装的误差,起到纠偏矫正的实施性成效,有效满足了电缆沟支架安装精度.55副/(d*人)*8人=440副/d7932副/440=18天操作简单8元/副安装精确对后序工艺不影响选择通过对比和分析,方案三不仅操作简单,而且能调节预埋件引起的误差,起到纠偏矫正的实施性成效,有效满足了电缆沟支架安装精度,而且解决了传统支

20、架焊接后二次镀锌的问题,因此一致认定第三种方案为最佳的使用方案。四、具体方案1.采用60*8扁铁与螺帽焊接1.1在加工厂内完成60*8扁铁每隔800mm打14孔,焊接m12螺帽工序图1螺帽焊接在扁铁上 图2:接地扁铁与粉刷面相平1.2通过设计人员的验算,满足设计要求。阶段效果检查:从现场安装情况看,满足预定要求,实施可行。2.确定安装顺序:扁铁先与预埋件连接,然后与电缆沟支架连接2.1在具体实施方案中明确施工顺序、步骤:1)在电缆沟侧壁砌筑时放置-6*80*80800预埋件。2)把带螺帽的接地扁铁连接在电缆沟侧壁的预埋件上。3)校正扁铁确保保扁铁顺直,在同一立面上,镶贴美纹纸对扁铁和螺栓孔进行

21、保护,防止电缆沟侧壁粉刷污染。4)电缆沟侧壁粉刷,扁铁与粉刷面相平。5)安装电缆支架在扁铁上,出现偏差利用电缆支架的可调孔进行调整;就位完成后,拧紧扁铁与电缆支架之间的连接螺栓2.2对操作人员做专项交底1)预埋件埋置水平间距及标高控制在10mm以内,预埋件立面超出砖砌体表面12mm。以确保电缆沟侧壁粉刷后扁铁与粉刷面相平。2)带螺帽的接地扁铁先与预埋件连接,然后与电缆沟支架连接阶段效果检查:通过实施,支架安装在满足质量要求的同时,施工速度大大加快。3.接地扁铁与预埋件焊接连接3.1项目部成员经分析后,编制焊接可行的焊接方案和节点详图。上下两道扁铁焊接在电缆沟预埋件上,应保证扁钢水平,电缆沟孔洞

22、应在同一水平线上,上下两道扁铁孔眼应在同一垂直线上。上下两道扁铁高差l2=600mm。3.2根据施工方案和节点详图,技术员在加工车间与进行扁铁与预埋件实验焊接,其强度可靠,实验未发现有问题出现。3.3对具体操作人员进行专项交底,通过交底,操作人员明确施工顺序和质量要求。3.4在现场实施过程中,我们提高了预埋件的预埋精度并注重预埋过程控制,对电缆沟侧壁预埋件安装检查,由抽查改为全数检查,从而满足安装要求,预埋件安装允许偏差合格率达95%,为加快电缆沟支架安装提供条件。阶段效果检查:通过实验和现场安装,焊接强度满足固定要求,可进行下道工序的实施。4.电缆沟支架上开设可调节孔用螺栓连接在扁铁上电缆支

23、架加工:为防止电缆滑脱,在电缆支架横档末端做齿状开口,用以绑扎电缆,防止滑脱。由电缆支架横档末端60mm处,每隔20mm,切割3mm齿口。在电缆支架竖档上下各开长圆可调节孔,上下孔距600mm,设置防震垫片,所有电缆支架开口位置一样。支架制作设置长圆孔支架安装装并利用可调孔调整位置与标高后,将电缆支架用m12螺栓设置防震垫片后拧紧固定在电缆沟通长扁钢上。支架安装时的效果支架采用螺栓拧紧安装后效果五、效果检查采取对策措施后,新的电缆沟支架安装改变了传统电缆沟支架安装方法。施工项目部会同监理单位、建设单位一起对支架节点安装进行了抽样调查,得出外观质量良好,电缆支架安装装偏差在5mm以内,合格率达9

24、5%以上(见活动前后对比图),原本支架安装时间需30天,通过以上措施和方法后,实际安装时间18天,提前了12天(见活动前后对比图),加快该分项工程安装速度,完成既定目标,为后续电缆安装提供了条件。经项目部成本测算和分析,通过此项研究,为项目部节约大量的电焊人工及材料等费用,加快了进度,经济效益达3万元。节约了成本,为企业获得了良好的经济效益。参考文献:1混凝土结构工程施工质量验收规范gb50210-2001;2电力建设施工质量验收及评定规程第 1 部分:土建工程dl/t5210.1-2005;3输变电工程建设标准强制性条文实施管理规程(2009版)4国家电网公司输变电工程质量通病防治工作要求及
