小湾水电站孔雀沟人工砂石加工系统规模大,且成品仓储量要求调节能力大,本文针对场地狭窄,地形陡竣,地质条件复杂的情况介绍了成品竖井群的布置方案,重点针对成品料仓竖井群的布置特点、施工环境、地质情况等因素,采用了不同的施工工艺进行竖井开挖施工,以确保制约本系统能否提前一年投产最关键的项目——成品料仓竖井群的施工按期完成。开挖施工过程中,在确保成品料仓竖井群的安全及整体稳定的同时,加快施工进度。采用的施工方法主要有反导井施工法、深孔分段爆破导井施工法、导井辐射孔扩挖法。 Xiaowan Hydropower Station Peacock ditch artificial gravel processing system is large, and the ability to regulate the finished product storage capacity is large, this article aims at the narrow site, steep terrain, complex geological conditions introduced the finished shaft group layout program, focusing on finished silos Shaft group layout characteristics, construction environment, geological conditions and other factors, the use of different construction techniques for shaft excavation construction, to ensure that the constraints of the system one year ahead of commissioning the most crucial project - finished silo shaft group construction Completed on schedule. During the excavation and construction, the construction progress will be accelerated while ensuring the safety and overall stability of the finished silo shaft group. The main construction methods used are anti-guide shaft construction method, deep hole section blasting guideway construction method and guide hole radiating hole excavation method.
