Abstract
With the precast T-beam of Batuta-Zhungeer Railway as the background, this paper introduces the technological innovation processes of precast T-beam's batch manufacturing in the cold and drought area, such as the manufacturing of the beams in workshop, using of box beam's experience to move the beams by girder gantry, assembling and disassembling of the hydraulic formwork of precast beam by hydraulic system's multi-point and synchronous control model, adopting of the automatic tension system, etc. As a result, these processes improved effectively T-beam's quality and schedule, and provided references to T-beam's mechanization and automation. Finally, the paper introduces the applications of T-beam's micro control system of static load test, and automatic processing of reinforcing bars.关键词
