南阳回龙抽水蓄能电站上库开挖技术

Excavation technology of upper reservoir at Huilong Pumped Storage Power Station in Nanyang

南阳回龙抽水蓄能电站上库,地形复杂,地质条件差,场地狭窄,开挖要求高,点多面广。通过不断调整和优化方案,保证开挖进度和质量;边坡、基础保护层开挖采用光面爆破,保证了平整度,减少了对边坡和建基面的成型影响。

At upper reservoir of Huilong pumped storage power station, topography is complicated, construction site narrow and excavation demand strict. By continually adjusting and optimizing scheme, the excavation of slope and base protection layer adopts smooth blasting, which insures the evenness and reduces the effect of blasting on the shaping of slope and foundation face.
