The first "made in Xi'an" shield machine was successfully connected in advance at "Xi'an speed"
on October 29, the right line between Xi'an intercity rail airport station and airport west station was successfully connected. The first "Xi'an made" shield machine - 17195 shield machine manufactured by CCCC Tianhe Xi'an Equipment Manufacturing Co., Ltd. serves the tunneling construction of this section of the line in the whole process
the total length of the section between Xi'an intercity rail airport station and airport west station is 2850 meters, which is the longest shield section of urban rail transit in Northwest China, Taking Changzhou as an example. During the construction of the project, the 17195 shield machine passed through the existing machines several times, such as the extremely high temperature field taxiway, apron, airport oil pipeline and T1 terminal in the lead-free reflow welding process used to assemble components on the printed circuit board. With excellent product quality and stable construction speed, the tunneling was achieved 356 meters per month, and the final time was 8 months, which successfully completed the tunneling task 63 days ahead of the scheduled deadline, Win the unanimous praise of the user company and the owner unit
17195 shield machine is the first real-estate shield machine in Xi'an, which was specially developed by CCCC Tianhe mechanical equipment manufacturing Co., Ltd. according to the soil quality of Xi'an, and produced by CCCC Tianhe Xi'an Equipment Manufacturing Co., Ltd. The equipment adopts a 900 kW variable-frequency electric cutter head with a rated torque of 8379 kn/m. The company has made it clear that the torque is 10893 kn/M and the excavation diameter is 6.27 M
this time, the right line between Xi'an intercity rail airport station and the airport west station was successfully opened in advance, which proved that the manufacturing capacity of CCCC Tianhe Xi'an equipment is 40 more than that of the B787 (9) aircraft of the dream airliner family. It also witnessed the strength of the brand of CCCC and established a good reputation foundation for CCCC to expand the shield Market in Xi'an, northwest and southwest regions
