全风化岩质正井开挖倒挂混凝土支护施工技术研究与应用

Research and Application of Inverted Concrete Support Technology for Excavation of Fully Weathered Rock Main Shaft

在抽水蓄能水电站竖井施工过程中,围岩地质条件较差是施工中的重点和难点,常常造成工期滞后、同时存在施工质量和安全问题。论文通过对抽水蓄能电站竖井的开挖支护出现全风化岩层如何施工进行探讨,有效解决了施工工序复杂等难点,保证了施工质量安全的同时,缩短了施工工期。

In the process of shaft construction of pumped storage hydropower station,the poor surrounding rock geological conditions are the key and difficult point in the construction,which often leads to the delay of the construction period and the problems of construction quality and safety.This paper discusses how to construct the completely weathered rock formation in the excavation and support of the shaft of pumped storage power station,effectively solving the complex construction procedures and other difficuties,ensuring the construction quality and safety,and shortening the construction period.
