Project Name:Chengdu-Guiyang Passenger Railway Caiba Minjiang River Bridge Location: Yibin City, Sichuan Province
Project profile: Caiba Minjiang River Bridge is a double-track passenger-dedicated railway bridge, with a total length of 1.19km and designing speed of 250km/h. Bridge spans are composed by precast box girders (13 X 32m), continuous beams (48m+80m+48m), through type steel-truss beams (140+224+140), cast-in-situ box girders (2 X 32m). The steel truss beams is 16-32m in height, and 14m in width. Caiba Minjiang River Bridge is one of key projects of Chengdu to Guiyang Railway in Sichuan Province, also the biggest Steel Truss Bridge in Yibin.

Challenge: During bridge joining process, for the long and heavy continuous steel-truss beams (140 + 224 + 140), how to precisely control horizontal movement, linear adjustment and positioning is one of the most critical parts.
|
|
Solution: Kattor’s intelligent hydraulic equipments and synchronous controlling technology were adopted to make the steel truss girder segments move smoothly and accurately to designed position.
Meanwhile, Kattor 3D Adjustment System (3DAS) was successfully applied on deviation-correcting of the beams, which has achieved precise adjustment and ensured each segment of the beam meet designed requirements.
