给水管网养护维护给水管网的设施,使其经常保持完好状态的工作。主要包括:管道的检漏和修漏;附属设施和配件的养护和检修;管道的清垢和防腐;防止管网污染;事故抢修和旧管道或配件的更新。管道的检漏和修漏 及时发现和堵塞管道渗漏是防止路面和建筑物坍塌、降低供水成本、提高管网水压和充分发挥给水系统效益的重要工作,应定期分区进行。检漏方法有:①观察漏水现象。留意管线附近的地面排水沟、岸边有否清水渗出,地面有否沉陷,墙壁有否开裂,积雪有否局部融化。②测听漏水声音。漏水一般都有声音,但有时比较微弱。在夜深人静无杂音时可用听漏棒或听漏仪沿管线查听。此法比较简单,效果也较好,是测漏的主要方法。③检查漏水量。在划定范围内,除一根支管外,关闭所有外通管道和用户支管上的阀门,通过支管流入测漏区内的水量,即得该区的漏水量。如果漏水量较大,先调度区内闸阀,找出漏水管段,然后听漏找出具体漏水处。如果漏水量小于规定数值,则不再查找漏水处。如果发现某一管段漏水情况频繁出现,应查找原因,必要时更新这一管段。附属设施和配件的养护 管网上的各种阀门、消火栓、增压泵站、调节水池、水塔以及仪表等都要经常养护。应加油润滑的部位要按期加油。备用的和不常用的水泵、阀门和消火栓等要定期启动,以便及时发现问题和修理。用户水表应定期轮流更换、送厂检修和校验。管道的清垢和防腐 由于流水的侵蚀,铸铁管内壁往往结垢,壁面变糙,阻力增加,以致流水不畅、供水能力下降,并影响水质。此时可开启消火栓冲出管道中的沉积物。但结垢严重时需用刮管器或刮管机清除。刮管器具有轮子,用绞车拖拉时,能在管中前后行走,底盘上设电动机和链锤。链锤为三、四根短铁链,一端固定在一个圆盘上,圆盘转动时,铁链飞直,鞭打管子内壁,击去水锈。装有驱动装置的刮管机,能在管中自己前后走动(见图)。刮管前应切除一段管道把刮管器纳入,割去的管段可用特制的对开管件替代,接口可用法兰。刮管以后,内壁喷涂水泥砂浆或塑料涂料。采用塑料涂料时管壁必须烘干。如果发现金属管道壁产生电化学腐蚀,要查清原因。可采用管外涂抹保护层(油漆、水泥砂浆、沥青、塑料等绝缘涂料层)或阴极保护法(导入直流电流使管道处于阴极电位)。防止管网污染 管道内壁生锈或有微生物繁殖时,除可能降低管道输水能力外,还可能使水质变浑带色。配水管终端水流不畅,常造成水质下降,应定期冲洗。结垢严重的管段也应冲洗或刮管。整个管网必须保持水中有剩余氯,大型管网可以考虑在管网中补充加氯。特别要防止混接(与不合格的水相连通),将导致不合格的水进入给水管网而造成污染。例如,用户自备水源不准与城市管网接通。龙头的安装要注意避免用水容器盛满时龙头口部淹没在水中(这时万一管道中出现负压,污染的水会倒流进入管网)。用户支管的连接由供水单位负责。对有自备水源的用户,对其内部连管工程要严加控制,以防止出现混接,城市采用分质供水时,必须有妥善的措施防止混接。事故抢修和旧管段或配件的更新 干管的爆裂、消火栓的撞坏、过河管道因意外严寒而冰冻、地震造成的各种破坏等都是有可能发生的,因情况不同发生事故的可能性也不同,但必须充分做好技术和器材准备。此外,不能使用的旧管段或配件及时更新。为了避免事故和及时抢修,也为了做好常规养护工作,整个管网特别是地下设施要有完备的资料图卡,并有一套存档,以便随时可以复制备用。
