水电工程非常规预应力锚杆补充预算定额编制简析

Supplementary budget quota of unconventional prestressed anchors in hydropower engineering

白鹤滩水电站非常规预应力锚杆使用气腿式风钻、制浆注浆一体机EB-40施工,直径小、长度短、施工更便捷、省时且支护效果良好。应用计时统计法,科学、真实地测定现场人材机消耗量,并进行数理统计分析,提出非常规预应力锚杆预算定额。价格水平测算符合工程实际施工成本,为投资控制、办理结算等提供了支撑。

Unconventional prestressed anchors in Baihetan hydropower station are constructed with the air-leg pneumatic drill and the pulping and grouting integrated machine EB-40.It has advantages such as small diameter,short length,convenience,rapid construction and good support effect.By scientifically measuring the consumption of labors,materials and machines on site and analyzing the measured data,the supplementary budget quota of unconventional prestressed anchors is drawn up.The price level is in line with the actual construction cost.It provides support for investment control and settlement.
