竹园堂隧道中隔墙施工法应用

Application of the construction method of central division wall of Zhuyuantang tunnel

通过对竹园堂隧道中隔墙施工法应用及研究 ,为软弱围岩、浅埋、大垮和特殊断面的隧道及地下工程施工提供了新途径、充实了新奥法的内容。与其它软弱围岩隧道施工方法相比较 ,不需要特殊的施工机具设备 ,能节省大量的机械台班费 ,且其施工安全可靠 ,可行性强 ,施工质量好。

Through the application of and research to the construction method of Central Division Wall of Zhuyuantang tunnel , a new construction way is provided for weak surrounding rock shallow buried large span or special cross-section tunnels and underground engineering, the new content is also enriched 'New Austria Method'. Compared with the construction methods of other weak surrounding rock tunnels, the advantage of this construction method is: it does not need the special construction machine and equipment, and may save plenty of the shift cost of machinery , its construction is safe, reliable and with strong feasibility, better in the quality.
