【Abstract】 This subject is one of the plan projects of research and manufacture of the national important technologies and equipments. Through the scientific research and constructing practice in The Qinshen Passenger dedicated railway. We had broken down the technical barrier for the great PC box beans erection and construction. Which are laid on bridges in the parallel double lines Whose traffic speeds are 200km/h and above, and We had successfully preparated a suite of related equipments, that made the bridge erection and construction equipments and technologies of our country be achieved breakthrough and reached the international actranced level at present. The status and experience above would be introduced systematically and briefly in this paper, these would be of benefit to research new products of a kind for highspeed railway construction in the next stage.更多还原
