Design of stepping type groove sawing equipment for underground deep narrow

针对堤坝防渗工程中静压成槽铺筑高聚物柔性防渗墙出现的成槽不连续、深度浅的问题,研究设计了步进式地下深窄槽锯切成型装备,本文介绍了该装备的行走机构、开槽机构和传动机构,提出了支撑悬架和移动主机间的步进式行走方案。基于所建立四足支撑缸悬架平台,结合火箭发射平台姿态调平技术,采用双轴倾角传感器确定系统施工倾角,研究了四足支撑平台在正常施工工况下各支撑缸的伸缩位移,优化了姿态调平算法。现场试验表明,该地下深窄槽装备锯切运行情况良好且达到预期效果。

For the problem of discontinuous groove formation and shallow depth in the static pressure forming of the groove and the high polymer flexible impermeable wall in the anti-seepage project of the dyke.In this paper,the stepping underground deep narrow groove sawing and forming equipment is researched and designed,and the walking mechanism,slotting mechanism and transmission mechanism of the equipment are introduced.It propose a step-by-step walking scheme between the supporting suspension and the mobile host.Based on the established quadruped cylinder suspension platform,combined with the attitude leveling technology of the rocket launch platform,the biaxial inclination sensor was used to determine the construction angle of the system.The telescopic displacement of each support cylinder of the quadruped platform under normal construction conditions was studied,and the attitude leveling algorithm was optimized.The field test shows that the equipment sawing operation is good and meet expectations.
