| 中文摘要:我国正处于钢筋混凝土结构应用与发展的大规模新建与修复改造并重阶段。为对钢混结构进行局部或整体的拆除与修复改造，传统机械破碎与爆破拆除方式存在施工效率低、安全隐患大和环境污染严重等问题，而利用金刚石工具对其进行静力切割拆除的施工方法在近年来得到迅速发展。目前，在钢混结构拆除与修复改造施工中应用最多的金刚石工具为金刚石薄壁钻头、金刚石锯片和金刚石绳锯。本文对上述3类金刚石工具在钢混结构修复改造施工中的应用现状、钻进与锯切机理、制造技术和施工工艺等研究现状进行了总结与分析，在此基础上指出了其可能的研究趋势与发展方向。研究成果可为金刚石工具在工民建和部分特殊领域的广泛应用提供技术参考。 |

| Abstract:Nowadays, building new reinforced concrete structures, repairing or reconstructing old structures are both important in China. To demolish and reconstruct a whole (or part of) reinforced concrete structure, conventional methods of mechanical disruption and blasting demolition have disadvantages of low construction efficiency, big potential security risk and serious environmental pollution. However, the construction method of static cutting demolition by employing diamond tools has developed rapidly in recent years. The most commonly used diamond tools include thin-wall diamond core bit, diamond saw blade and diamond wire saw. The application status, drilling and sawing mechanisms, manufacture technologies, as well as the construction parameters of the above mentioned 3 kinds of diamond tools employed in repair and reconstruction of steel concrete structure are summarized and analyzed in this paper, on the basis of this, the possible research trends and development directions are obtained. The research findings can provide technical reference value for wide application of diamond tools in civil engineering and some special fields. |
