摘要
随着我国水利、交通、能源等基础工程蓬勃发展,隧道及地下工程建设迎来了高速大发展时期.首先,介绍了钻爆法施工装备发展,依次从"人工"、"小型机械化"、"单一工序大型机械化"、"全工序大型机械化"等4个阶段进行阐述;然后分别对目前钻爆法在施工过程中存在的岩芯收获率、超欠挖控制、拱架设立效率、湿喷回弹、锚杆注浆密实度等问题的现状及发展趋势进行了阐述和思考,并提出了钻爆法施工装备、协同管理平台、绿色施工装备等未来着重发展的建造技术;最后,对钻爆法隧道智能装备与隧道智能建造发展前景进行了展望,以推动我国隧道工程向无人、智能、信息、环保、节能与可持续的目标发展.
Abstract
With the vigorous development of water conservancy,transportation,energy,and other infrastructure proj-ects in China,tunnel and underground engineering construction has entered a period of rapid and significant growth.First,the development of drill and blast construction equipment is introduced,elaborated in four stages:"manual","small mechanization","single process large mechanization",and"full process large mechanization".Second,the current status and development trends of problems encountered during drill and blast construction,such as core re-covery rate,overbreak and underbreak control,arch erection efficiency,rebound in wet spraying,and anchor grouting density,are expounded and discussed.The paper also proposes the future key development fields in construction technologies,including drill and blast construction equipment,collaborative management platforms,and green con-struction equipment.Finally,the paper looks ahead to the prospects of intelligent equipment and intelligent con-struction in drill and blast tunnelling,aiming to promote the development of China's tunnel engineering towards un-manned,intelligent,informative,environmentally friendly,energy-saving,and sustainable goals.
