“一体化提升系统”在隧洞施工中的应用

The Application of the Integrated Liftsystem in the Construction of Tunnel Excavation

小断面长隧洞施工中,以大坡度长斜井作为施工支洞时,支洞运输方案的选择是关键。本文依托云南省牛栏江-滇池补水大五山隧洞工程,通过对不同形式的运输方案进行比选,提出并设计了"一体化提升系统"[1]。结果表明,该运输方式的应用,减少了中间环节,降低了生产成本,提高了设备利用率,确保了工程工期。

When the long inclined shaft with large slopes is used as the working tunnel in the construction of long tunnel with small sections ,it is important to choose the right transportation scheme .By comparing some methods ,this paper proposes a new way called“integrated liftsystem”in the construction of Kraaljiang-Dianchi Lake Water from five mountains in Yunnan Province .The result shows that this transportation reduces successfully the intermediate links and production costs ,thus improving equipment utili-zation ,and ensuring the project as planned .
