TBM Boring Machine Reached at Station
The twin 9km tunnels of the Metro Tunnel were built using four TBMs. Each TBM was 120m in length, 7.28m in diameter, and weighed more than 1100 tonnes. The cutter head, which weighed 100 tonnes and operated like a drill capable of boring through rock six times harder than concrete, was the most substantial part. The cutter head’s face had a diameter of 7.28 meters. Each TBM has a staff of up to ten persons working on it at once, including the TBM operator. The TBMs were completely furnished with amenities for our employees, including an office, kitchen, and restrooms. They were staffed and monitored 24 hours a day, 7 days a week. They used a cutting-edge navigation system that made sure they excavated precisely along the alignments of the tunnels.
Plowing of HDPE pipes along the railway
Despite being relatively new to the railroad industry, HDPE pipes are quickly gaining favor in drainage applications for railroads and intermodal transportation. HDPE pipe provides superior structural performance, long service life, and great pricing. When compared to concrete and metal pipe, lightweight 20-foot pipe lengths accelerate installation, reduce installation costs, and increase job site safety. The resilience of polyethylene resists corrosion, chemical ᴀᴛᴛᴀᴄᴋ, and abrasive fluxes while providing insulation from stray currents.
SANYI EBZ200 Roadheader
On “Shakhtar Sibirskaya” LLC, new Roadheaders EBZ200 have arrived. Sany Heavy Equipment Co., Ltd. constructed 3 Roadheaders EBZ200, which “Shakhtar Sibirskaya” LLC purchased and received in August 2019 as part of the investment and production program (Cʜɪɴᴀ) This company is a leader in the production of mining equipment worldwide. The biggest coal firms in Kuzbass took into account the technical traits and expertise of road headers produced by Rᴜssɪᴀn and foreign manufacturers when working on this delivery.
One road header is currently operating in rocks with a strength factor of f10 and is launched on the flank track shaft. A 60-meter sink is planned for October. At the Central Remsberg industrial site, service engineers put together the other 2 road headers. In the fourth quarter of 2019, marching crews’ work on cutting horizontal drifts on the coal seam will reach its full operating capacity.
