龙麟宫隧道管棚支护施工质量问题分析与处理

龙宫麟隧道洞口段有一溶腔,围岩较为破碎,工程地质条件差,设计中采用长管棚进行岩体加固,遵守隧道的"早进晚出"原则,确保能够提前进洞。文章结合龙麟宫隧道应用管棚支护工程实例,分析探讨了管棚支护技术施工质量问题及解决方法。实践结果表明,该处理方法可以克服传统施工技术存在的缺点,达到了较好的支护效果,可供类似条件的隧道施工提供参考。

Analysis and Treatment of Pipe Shed Support Technique in Long-lin Temple Construction Quality

Long-lin Temple Portal has a melting chamber,the more broken rock,engineering geological condition is poor,long-pipe shed used in the design studio for rock reinforcement,compliance with the tunnel＂early into the evening out＂principle to ensure that early hole.By combination with Long-lin Temple tunnel applications Forepoling engineering examples,this paper analyzes and discusses Forepoling technical construction quality problems and solutions, practical results show that the approach can overcome the shortcomings of traditional construction techniques to achieve a better support effect,provide a reference for similar conditions of the tunnel construction.
