摘要
反井钻机开挖导井朝着大直径工艺发展,而水电行业现有相关定额中无反井钻机开挖大直径导井(孔径>2.0m)相关定额。对白鹤滩水电站导井开挖过程中统计的实测资料进行整理、计算分析,编制反井钻机开挖3.5m导井补充定额。与有色金属工业预算定额、类似工程实施价对比,结果表明补充定额编制合理,可为类似工程的单价编制、成本控制等提供参考。
The pilot shaft excavation with raise boring machine is developing towards large diameter technology,but there is no relevant quota for large diameter pilot shaft(D>2.0 m)excavation in the existing relevant quota of hydropower industry.This paper analyzes and calculates the measured data of pilot shaft excavation in baihetan hydropower station,and makes out the supplementary quota of 3.5m pilot shaft excavation with raise boring machine.Compared with the other quota and implementation price,the results show that the supplementary quota is reasonable,which can provide reference for price compilation and cost control of similar projects.
