摘要
5号措施斜井穿过强风化带和两个含水层,工程地质条件较差,给施工造成了极大的困难。采用短掘短砌施工方法,通过建立有效的临时排水系统,加强临时支护,优化爆破参数等技术措施,保证了施工质量和进度。
No.5 Measures＇ Inclined Shaft has gone through a strong weathered zone and two aquifers. Its engineering geological conditions are relatively poor, the construction is extremely difficult. During the construction process, we have adopted a Short Segment Driving and Masonry to build an effective temporary drainage system. And have strengthen the temporary support and optimized the blasting parameters such as technical measures to ensure the construction quality and progress.
