Nepal’s First TBM bores 1,000 Meters in One Month | The
Jul 23, 2018· Nepal’s first tunnel boring machine, a 506 m (166 ft) diameter Robbins Double Shield, is living up to the nation’s high expectations The TBM, supplied in summer 2017 for the Bheri Babai Diversion Multipurpose Project (BBDMP), recently bored over 1,000 m (3,280 ft) in one month and has been averaging an impressive 800 m (2,630 ft) per month(2) In planning a project schedule, the lead time needed to get a TBM onsite varies from perhaps 9 to 12 months for a new machine from the time of order, to perhaps 3 to 6 months for a refurbished machine, and to nearly no time required for a direct reuse without significant repairs or maintenanceTunnel Boring Machine (TBM) – Advanced Technology Consultants
Advanced prediction of tunnel boring machine performance
Mar 10, 2020· Machine learning model developed based on big database from TBM construction of YinSong Diversion Project in China • Total thrust and cutterhead torque in the stable period predicted through the data in the rising period of TBM boring • Variation of the TBM performance is superior to the classical theoretical CSM model •A tunnel boring machine (TBM) consists of a shield (a large metal cylinder) and trailing support mechanisms At the front end of the shield a rotating cutting wheel is located Behind the cutting wheel there is a chamber where, depending on the type of the TBM, the excavated soil is either mixed with slurry (socalled slurry TBM) or left asisBORED TUNNELS Victor Miguel Ponce, Victor Ponce, Miguel
