虹梯关特长隧道14.1米自行式液压衬砌台车的应用
摘要：虹梯关特长隧道是目前国内第三长大公路隧道,全长13.1km，为目前国内在建最长特长隧道之一，同时也是本线的控制性工程，为左右线分离式隧道。由中铁十二局承建的长平高速lj5合同段为隧道进口的施工任务，左洞起讫里程为K11+088～K18+300，长7212m；右洞起讫里程为YK11+088～YK11+314.77，长7226.77m，左右洞均为直线，设计线间距25m，隧道建筑界限：宽10.25m（单洞）、高5.0m。K16+050处设1#2#通风斜井，正洞洞口至斜井距离4962m，施工方案为正洞独头掘进完成正洞施工任务，施工工期紧，压力大。衬砌能否及时跟进直接影响到施工进度及施工安全。采用14.1米长台车后，取得了良好的经济效益，有效了保证了施工工期。本文结合工程项目实践与大家一起分享、探讨，以期在集团公司推广或今后在同行业中采纳推广。

Abstract: HongTiGuan tunnel is the present domestic third grow up highway tunnel, the 13.1 km, for the domestic one of the longest tunnel construction, but also the line of control project, for line separate tunnel around. The China railway construction bureau of twelve ChangPing high-speed lj5 contract section of tunnel construction of import task, left hole for commencement mileage K11 + 088 ~ K18 + 300, long 7212 m; Right from YK11 hole for the mileage of 088 ~ + YK11 + 314.77, 7226.77 m long, or so hole are to linear, design line spacing 25 m, tunnel construction boundaries: wide and 10.25 m (single hole), high 5.0 m. K16 + 050 place set 1 # 2 # ventilation shafts, are inclined to hole hole from 4962 m, the construction scheme is hole for the tunneling complete is hole head construction projects, construction period tight, pressure. Lining can follow up in time directly affect the construction progress and construction safety. Use 14.1 meters long after the car, and achieved good economic benefit, effectively ensure the construction period. Combining with the project project practice and share with everyone, the reference in the group promotion or future in the industry adopted promotion.
