摘要:

为解决隧道钻爆法施工整体机械化程度较低、施工环境恶劣和工人劳动强度大等问题,以郑万高铁湖北段隧道工程实践为依托,从大断面快速修建技术理论研究、机械化配套设备、机械化配套条件下施工技术和信息化系统应用等方面总结郑万高铁湖北段隧道大断面修建关键技术,即: 在建造理念上由塌方荷载发展为变形控制设计方法;在施工工法上由分步、分部开挖法发展为大断面和全断面开挖法;在支护形式上对初期支护和超前预加固进行强化(中空、砂浆锚杆强化为涨壳式低预应力锚杆,喷射混凝土采用高强、早强混凝土);在施工装备上由小型机械化、半机械化开挖施工阶段转变为多臂凿岩台车为主的机械化作业;在工序作业上由单一工序机械化施工转向全工序机械化配套作业;搭建信息平台,将手机作为管理工具,借助物联数据进行施工管理。通过对隧道施工大型机械化配套及信息化应用的探索和创新,由理论到实践,形成了一整套机械化配套条件下的大断面隧道安全、快速、标准化施工工法及工艺,推动隧道的整体施工水平和综合管理能力。

Abstract:

The drilling and blasting method for tunnel has many disadvantages such as low mechanization, bad construction environment and high labor intensity. Hence, the large crosssection construction technologies for Hubei Section on ZhengzhouWanzhou Highspeed Railway are summarized from the aspects of theoretical research, mechanized matching equipments, and construction technology and informatized system application. The technologies adopted include: (1) The construction idea of collapse load is changed into deformation control design. (2) The construction method of stepped excavation and bench method are changed into large crosssection and fullsection method. (3) The primary support and advance prereinforcement are strengthened by changing hollow grouting anchor bole by low prestressed expansion anchor bolt and using earlystrengthened shotcrete with high strength. (4) Multiboom rock drilling jumbo is adopted. (5) The single process mechanized construction is changed into whole process mechanized matching. (6) The information platform is established to carry out construction management. A series of technologies for safe, rapid and standardized large crosssection mechanized tunnel construction is obtained, which can promote the tunnel construction and management level.

Key words: ZhengzhouWanzhou Highspeed Railway, tunnel engineering, mechanized matching, fullsection excavation method, informatized application
