箱型拱桥主拱圈施工是拱桥施工中难度最大、标准最高的关键工序,针对200m级箱型拱桥的挂篮悬臂浇注施工,以木蓬特大桥为依托,重点研发了最核心的塔架系统、扣锚索系统和挂篮系统等成套设备。采用扇形式扣挂塔架系统、新型锚箱和倒挂式三角斜爬挂篮等核心设备,在木蓬特大桥成功应用,表明该套设备具有安全可靠性高、操作方便、经济性好、适应性强等特点,为进一步推广至300m级拱桥悬浇施工奠定了基础。
The construction of the main arch of the box arch bridge is the most difficult and highest standard in the construction of the arch bridge. For the 200m-class box arch bridge with hanging basket cantilever pouring construction, with the Woodpound Bridge as the basis, the most important tower system , Buckle cable system and hanging basket system complete sets of equipment. The use of fan-shaped buckle tower system, a new type of anchor box and hanging upside down triangular hanging basket and other core equipment in the successful application of wooden bridge, which shows that the set of equipment with high safety and reliability, easy operation, good economy, adaptation Strong and other characteristics, laid the foundation for further popularization to 300m arch bridge cantilever construction.
