一、电缆工程概算 近年来采用电缆方式供电工程施工项目逐渐增多,因为电缆供电可靠性好,不容易受外界气候及机械损坏,环境美观。但是从概算角度分析,则电缆供电线路比架空线供电线路的造价高得多。 定额中电缆工程项目主要有电缆沟铺砂盖砖(或盖混凝土板)、密封式电缆保护管、高压电缆终端头、电缆沟支架的制作和安装、电缆梯架的制作和安装、电缆敷设、电缆托盘安装等。
First, the cable project budget In recent years, the use of cable power supply engineering construction projects gradually increased, because the cable power supply reliability is good, not easily affected by external weather and mechanical damage, beautiful environment. However, from the point of view of budgetary analysis, the cost of the cable power supply line is much higher than that of the overhead line power supply line. The fixed cable projects mainly include cable trench sand-covered bricks (or covered concrete slabs), sealed cable protection pipes, high-voltage cable terminations, cable groove brackets, and the manufacture and installation of cable ladder frames, and cable laying. Cable tray installation and so on.
