Anhui Yonggu Steel Structure Co., LTD

The steel pipe arch installation project of the Hulupo Special Bridge on the Guinan Railway is located in a narrow area with a large elevation difference. It is situated beneath the flight route of Longdongbao Airport and simultaneously crosses the operational line of the Shanghai-Kunming Railway. It is subject to dual control of the existing line and the high-altitude area, resulting in limited construction space and extremely high operational difficulty. Two 1x104m tie bar arches are used to span the expressway between the abutments. Our company has a production capacity of 1,450 tons.
