国内外当前形势下旋挖钻机的发展前景(中文4200字,英文2600字)
    随着全球经济的快速发展，继续扩大对基础设施的范围，以人为本和保护，直到不断加强基础设施，特别是现浇混凝土桩的桩位与环境有关的法律和规章的设想基础他几乎取代了空间应用范围广泛的基本基础。扶轮社是因为其效率高，污染少，更多的全面发展的功能特点，以满足钻机在就地演员，在国内建设的需要，混凝土桩已被广泛使用。
    旋挖钻机的旋挖钻机在英国除了各扶轮社分销业务的斗争中，我们需要短期和长期螺旋螺杆钻分布，长城钻井套管安装符合动摇抓斗控制设备等 - 将套管施工;抓斗与地下连续墙伸缩杆指导，对硬岩破碎施工直接到户;进行更换后的植物和Jet建设的是建设周期;配置可以液压锤，振动锤，柴油锤了一系列其他形式的桩等施工。

Rotary drilling rig in the current situation and prospect of development at home and abroad
With the rapid development of the global economy, continuing to broaden the scope of infrastructure, people-oriented and the idea of protecting the environment-related laws and regulations until the continually strengthening the infrastructure, especially the piles of cast-in-place concrete pile foundation he has almost replaced the basic foundation for a wide range of applications of space. Rotary drilling rig because of its high efficiency and less pollution, more functional features of the comprehensive development to meet the needs of the cast-in-place concrete piles in the domestic construction has been widely used.
