摘要:

近年来我国在岩石地层的地铁隧道施工需求越来越大,在青岛地铁双护盾TBM施工过程中,龙门吊垂直出渣方式严重制约了TBM施工速度。虽然龙门吊用于地铁土压平衡盾构施工渣土垂直提升,技术成熟且应用广泛,但在岩石掘进机施工中的应用效果不佳,因此有必要进行探索和变革,采用更加适用的方法以充分发挥TBM快速施工的优势。分析龙门吊垂直提升石渣对双护盾TBM施工效率的影响,调研相关行业的物料垂直提升方法,从技术、经济和工期3方面分析龙门吊与垂直皮带机出渣的差异。在城市地铁双护盾及开敞式TBM施工中,垂直皮带机出渣技术具有运输效率高、不占用TBM掘进时间、故障率和综合成本低的优势,可为充分发挥TBM掘进效率提供良好保障,具有很大的市场推广价值。

Abstract:

In recent years, the Metro tunnel construction in rock strata has become more and more common in China. The TBM construction speed is restricted by method of vertical mucking by gantry crane used in doubleshield TBM tunneling in Qingdao. The effect of vertical mucking by gantry crane used in EPB shield is good and popular. The influence of vertical mucking by gantry crane on construction efficiency of doubleshield TBM is analyzed. The vertical hoisting methods of material in related projects are studied. The differences between gantry crane and vertical belt conveyor are analyzed in terms of technology, economy and construction schedule. The vertical belt conveyor used in doubleshield TBM and open TBM has many advantages, i.e. high transportation capacity, low failure rate and low cost; and it is worth popularizing.

Key words: vertical belt conveyor, TBM, Metro, mucking
