枕头坝一级水电站开挖料的回采利用

Re-use of Excavated Materials in Zhentouba I Hydropower Station

水利水电工程开挖渣料较大,因工程弃渣带来的环保成本也较大。分析开挖渣料的质量、储量,对可用渣料的开挖、储存、回采利用进行有效管理,不仅能节约弃渣成本和料场的开采费用,降低工程投资,还能带来很好的环保效益。枕头坝一级水电站通过对开挖渣料各个环节的管控,实现了料场零开挖量的目标。介绍了该工程的石渣管理经验,可为类似工程提供参考。

The volume of excavated material in the construction of water resources and hydropower projects is usually larger, and the environmental cost for excavated material treatment is also greater. By analyzing the quality and quantity of excavated materia｜ and conducting an effective management on the excavation, storage and re-use of excavated material, the costs of excavated material treatment and aggregate stockyard excavation can not only be saved, but also a certain environmental benefits can be achieved. The re-use of excavated material in Zhentouba I Hydropower Station project achieves the goal of no aggregate excavation from stockyard. The management experiences on excavated material in the project are introduced.
