印度孟买一直面临着管线老化漏水导致雨季饮用水供应不足的困境,因此决定修建新的输水隧道。该项目承建商Unity-IVRCL公司(以下简称“UIJV”)采购1台罗宾斯主梁式硬岩掘进机用于开挖隧道,掘进机于2012年6月始发,2014年年初顺利完成了全长8.3 km隧道的掘进工作。这台直径6.25 m的掘进机在掘进过程中展示了卓越的性能,保持着骄人的掘进速度。UIJV称,罗宾斯掘进机在硬岩地层中表现优异,实现了月进尺870 m和日进尺58 m的高速掘进,刷新了印度掘进隧道的掘进纪录。项目的整条隧道都呈现出复杂的地质条件,其中包括玄武岩、裂隙地层和水涌。在不良的地质条件下作业,罗宾斯掘
Mumbai, India, has been facing the dilemma of inadequate potable water supplies during the rainy season as a result of pipeline aging leaks, and has decided to build a new water tunnel. The project contractor, Unity-IVRCL (“UIJV”), procured 1 Robbins girder TBM for excavation of tunnels. The boring machine was launched in June 2012 and smoothly in early 2014 Completed tunneling of 8.3 km in length. This 6.25 m diameter roadheader demonstrated excellent performance during the tunneling process and maintained impressive tunneling speeds. UIJV said the Robbins roadheader has performed exceptionally well in hard rock formations, achieving high-speed headings with a monthly footage of 870 m and a daily footage of 58 m, setting the record for tunneling in India. The project’s entire tunnel presents complex geological conditions, including basalt, fissured formation and water surge. Working in bad geological conditions, Robbins digs
