摘要:伴随着城市现代化的建设对市容市貌的美观要求,越来越多的城市照明线路由架空转为埋地方式,从前蜘蛛网式的线路由统一的预埋式管沟替代,即保证了城市立体空间的美观大方还大大提高了线路运行的安全。随着经济水平的发展提高和管道工艺的革新,电缆埋管敷设的设计标准和产品标准也随之变化。怎样结合本地的自然地理条件,结合当前的经济发展水平及未来的发展空间去选择一种性价比最优越的管材并与实际的设计工作相结合是本文论述的重点,从而达到规范标准化设计,利于后期施工及便于维护的一个综合目的。

Abstract: with the construction of city modernization in the city ShiMao beautiful demand, more and more city ZhaoMingXian routing overhead to buried way, once upon a time web type line by a unified embedded type pipe trench alternative, i.e., to ensure the urban stereo space is beautiful and easy also greatly improved line operation safety. With the development of the economy and improve pipe technology innovation, cable buried piping design standards and product standard changes. How to combined with the local natural and geographical conditions, combined with the current economic development level and the future development space to choose a price the most superior pipe and practical design work is the combination of the focus of this paper, in order to regulate the standard design, which will help the construction stage and easy to maintain a comprehensive purpose.
Key words: the city street lamp cable buried laying advantages and disadvantages is more normative design
引言:
电缆埋地敷设有着自己特定的要求,比如说:应解决电缆遭受机械性外力破坏、散热、耐腐蚀、避免涡流损耗等问题;满足安全保护要求条件下,应尽量使综合造价相对较低,且便于敷设、维护;下面我就目前设计和使用较多的三种管材(PVC管、无碱树脂玻璃钢夹砂管、涂塑钢管)进行综合性的对比分析,并针对三种管道的发展现状及综合性价比提出对设计的规范要求。
PVC管、无碱树脂玻璃钢夹砂管、涂塑钢管产品介绍及市场现状。
1.1PVC管
硬聚氯乙烯塑料电缆导管(俗称:PVC管)是以聚氯乙烯(PVC)树脂为主,加入有利于提高导管力学及加工性能的添加剂,在一定的温度和压力下在模具内经挤出成型的一种实壁结构的塑料电缆导管。……
