随着特高压交流输电线路走廊及沿线地形地貌、地质等工程条件愈趋复杂,以及环境保护越来越受到重视,岩石锚杆基础因其安全可靠、先进适用,在特高压交流输电线路基础工程中应用面越来越广。因现行电力工程建设概、预算定额与费用计算标准滞后于特高压交流工程新技术应用,目前尚无岩石锚杆群桩基础施工费用标准。本研究结合特高压交流工程岩石锚杆施工方案、工艺标准,并通过实地调研、工序采集、工时测量、理论计算等方式测算了施工人材机消耗量,经数据处理、比较类推、经验估计等方法测算了施工费用标准,建立人材机消耗量配置模型,用于特高压交流工程施工费用标准补充研究。文章对建立特高压交流工程科学定额与费用计算体系、有效控制工程造价及树立特高压交流工程建设标杆具有重要现实意义。
With the increasing complexity of the terrain and geology along the corridor and along the terrain of UHV AC transmission lines, as well as the increasing emphasis on environmental protection, the rock bolt foundation is advanced and applicable due to its safety and reliability. In the UHV AC Transmission Line Foundation Project In the application of more and more widely. Due to the current construction of electric power projects, the standard of budget quotas and fees lags behind the application of new technologies in UHV AC engineering. Currently, there is no standard of construction cost for rock bolting group pile foundation. In this study, combined with the rock bolt construction program and technology standard of UHV AC engineering, the consumption of construction human-machine was calculated through field investigation, process collection, working time measurement and theoretical calculation. After data processing, analogy and experience estimation The construction cost standard is estimated, and the configuration model of human resource machine consumption is established to supplement the construction cost standard of UHV AC engineering. The article is of great practical significance to establishing the scientific quota and fee calculation system for UHV AC engineering, effectively controlling the project cost and establishing the benchmark for UHV AC project construction.
