Tianjin Subway Line 6 contract section 7 ~ Jin ~ North Section shield construction

The purpose of preparation for the operation of tunnel battery electric locomotive to meet the safety requirements to prevent  EPB tunnel battery electric locomotives on a large gradient rail stop due to changes in load and other reasons  appear slip wounding, damage to machinery accidents, to ensure the smooth construction of shield construction work, the development of this program .

Construction Scope and General situation: The main construction contents of the shield tunneling project of Jin-Min-Bei Shield Tunnel include reinforcement of the foundation of entry and exit tunnels and excavation in the interval. Civil Rights Gate Station ~ Beining Park Station Section: single-hole single-lane two-lane dual-zone project, the range of mileage for the DK9 +923.541, the end of the mileage DK10 +601.821, interval right line length of 678.28 meters, left line 674.632m long, The radius of the curve is 330m and the maximum gradient is 5 ". The thickness of the covering soil at the top of the interval tunnel is about 10.4 ~ 13.5m and the depth of the tunnel floor is about 16 ~ 23m. The spacing between the left and right of the interval is about 15-39m. Internal plan min. radius curve is 450m,max. gradient 28’’. Interval connect start from Admiralty River Avenue Station ~ Civil Rights Gate Station Interval. This project adopts the durable high efficient battery electric locomotive on the straight road. When the single battery powered locomotive construction speed (22km / h), the braking distance is not more than 20m. On the 35 "ramp, when the tunnel battery locomotive pulls 200t (the tunneling battery locomotive has brake, its braking rate is not less than 0.7) , The entire tunneling traction marshalling speed of 2.8m / s braking distance of not more than 40m, to meet tunneling engineering needs.
