摘要:

为满足特长铁路隧道建设期施工通风和运营期防灾救援的需要,打造立体通风方式,加快隧道施工速度,避免因传统钻爆法带来的安全和环保方面的问题,以敦格铁路当金山隧道竖井为例,通过对施工方法的研究和工程特点的分析,进行方案比选,结合2号竖井的地质条件,改进反井法施工工艺。结果表明: 1)采用气动潜孔锤技术施工导孔与BMC600反井钻机施工扩孔相结合的方式,使用KXP-2D(S)数字罗盘测斜仪进行测斜,成功钻成直径为3.0 m、深度为442 m的深竖井; 2)通过合理控制钻进参数,可以有效控制竖井偏斜,偏斜率仅0.8%,成井速度快、质量好、安全系数高; 3)反井法一次成井施工铁路隧道深竖井完全可行,机械化程度高,充分显示了反井法的优越性和先进性。

Abstract:

In order to meet the requirements of ventilation during construction and disaster prevention and rescue during operation of extralong railway tunnel, built spatial ventilation mode, rapid tunnel construction speed and avoid safety and environmental problems caused by drilling and blasting method, the characteristics of construction of vertical shaft of Dangjinshan Tunnel on DunhuangGolmud Railway are analyzed, schemes are compared and selected, and the raiseboring method for vertical shaft No. 2 is optimized based on its geological conditions. The results show that: (1) A deep vertical shaft with diameter of 3.0 m and depth of 442 m is successfully completed by using pneumatic DTH, BMC 600 raiseboring machine and KXP2D(S) digital compass inclinometer respectively in pilot hole drilling, hole enlarging and tilt angle measuring. (2) The deviation rate of the shaft is successfully controlled at 0.8% by rationally controlling drilling parameters; and the rapid and safe shaft construction with good quality has been guaranteed. (3) The onetime shaft completion by raiseboring method is feasible for railway tunnel vertical shaft; and its high mechanization level shows its superiority and progressiveness.

Key words: railway tunnel, deep vertical shaft, raiseboring method, raiseboring machine, deviation control
