直埋光缆工程工程量和主材用量统计方法与技巧解析

通信线路工程中的直埋施工形式，在我国发达的通信网络中占有十分重要的地位。直埋光缆线路主要存在于我国通信线路网的一、二级长途干线及少数本地网线路中。它本身具有施工快捷、适合地形广泛、工程造价较低等特点。直埋光缆线路工程在陆地部分一般采用钢带铠装光缆，水线部分需采用钢丝铠装光缆，其保护措施主要有（横/竖）铺砖保护、水泥砂浆袋保护、顶管保护、水泥盖板保护、砌坡/砌坎保护、堵塞/封石沟保护、安装宣传警示牌以及防雷、防蚀保护等。这些特点决定了在对这类工程进行预算编制———统计工程量、套用通信定额及填写预算表格时也具有其本身的特点。本文将结合具体工程案例详细介绍工程量和主材用量统计的顺序、方法与技巧。

Analysis on statistics methods and skills of engineering quantity and principal material usage in direct buried cable line engineering

Buried cable line construction in communication line engineering plays a very important role in our well-developed communication network. Budget estimate arrangement of single project of buried cable line has its own characteristics, which involve engineering construction survey, excavation and backfill earthwork, all kinds of markstone installation, optical cable jointing and test, line protection, etc. The statistics of engineering quantity and principle material usage is the difficult point. Combined with the actual engineering case, this paper introduces the order, methods and skills to do the statistical work accurately in detail.
