摘要
针对高海拔地区隧道施工受低气温、低气压、低含氧量气候环境影响,导致施工机械设备配置存在整体功效不足或功效浪费这一现状,结合高海拔超特长公路隧道——317国道雀儿山隧道,提出一套较为完善、合理科学的施工设备配置方案,具体包括钻爆、挖运、供风、通风、供水、供电、供暖、供氧八类主要设备配置。结合雀儿山隧道施工设备配置情况,进一步研究提出高海拔隧道钻爆法施工设备全电化作业模式设备配置方案,并从“油改电”技术、配套的施工组织和管理以及电动工程设备相关电池技术等方面进行展望。
In view of the fact that the tunnel construction in high altitude areas is affected by the climate environment of low temperature,low atmospheric pressure and low oxygen content,which leads to the overall efficiency shortage or waste of construction machinery and equipment configuration,this paper proposes a relatively complete,reasonable and scientific construction equipment configuration scheme based on the high-altitude ultra-long highway tunnel,the Que'ershan Tunnel on National Highway 317.Specifically,it includes eight main equipment configurations:drilling and blasting,excavation and transportation,air supply,ventilation,water supply,power supply,heating and oxygen supply.Based on the configuration of construction equipment for the Que'ershan Tunnel,a fully-electrified equipment configuration plan for high-altitude tunnel drilling and blasting construction is further studied and proposed,and relevant prospects are made from the aspects of"oil to electricity"technology,construction organization and management,and battery technology related to electric engineering equipment.
