简易塑料管道的设计造型与建设李馨春由于目前基建资金紧张，因此简易管道在光缆设计中经常采用，而塑料管道具有重量轻、接头少、施工速度快等特点，因而成为简易管道的首选材料。目前在工程设计中，简易管道多选用Ｄ６０塑料管，不修管道基础，在电缆沟中直接放两根塑料... Simple plastic pipe design and construction Li Xinchun Due to the current capital construction funds are tight, so simple pipelines are often used in optical fiber cable design, and plastic pipe with light weight, less joints, construction speed and other characteristics, and thus become the preferred material for simple pipe. Currently in engineering design, simple pipelines use D60 plastic pipe, do not repair pipe foundation, put two plastic cables directly in the cable ditch ...
