千米小型斜井及隧洞施工技术

Construction Technology of Kilometer Small Inclined Shaft and Tunnel

为了提升小型斜井及隧洞的施工产值、效率,并建立小型斜井及隧洞施工技术模块,笔者以山西引黄工程5标2号隧洞为案例,根据现场施工条件,以施工斜井提升、提升能力、月进度指标、施工工艺组织为要点,以施工经验为基础,通过公式计算与分析,逐一解决了施工中难点,为小型隧洞、小型斜井施工产值、效率分析提供了一个完整的思路和参照。

In order to improve the construction output value and efficiency of small inclined shafts and tunnels, and to establish small inclined shaft and tunnel construction technology modules, the author takes No. 2 tunnel of 5 bid section of Shanxi Yinhuang Project as a case. According to the site construction conditions, the construction of inclined shaft lifting,lifting capacity, monthly progress indicators, construction technology organization are the main points. Based on construction experience, formula calculations and analysis are performed to solve the difficulties in construction one by one, and providing a complete ideas and references for the analysis of the output value and efficiency of small tunnels and small inclined shaft constructions.
