Novel girder erection equipment and erection method
The invention discloses novel girder erection equipment and an erection method. The novel girder erection equipment comprises a via hole girder, an inner guide girder and a girder falling frame, wherein an inner guide hole is horizontally formed in the via hole girder in a penetrating mode, the inner guide girder is arranged in the inner guide hole in the via hole girder in a penetrating mode, anda power pulley mechanism for driving the via hole girder or the inner guide girder to do linear displacement is arranged between the via hole girder and the inner guide girder; a girder falling portal for lifting or descending a girder to be erected walks on the via hole girder; and the via hole girder is a specially-made steel box girder. According to the novel girder erecting equipment and theerecting method, the rule that a bridge girder erection machine must be used for traditional girder erection is broken; complicated and dangerous high-difficulty and high-risk operation of assembling,hoisting, load-bearing moving and hole passing during girder erection of the bridge girder erection machine is abandoned, the problems of construction safety and construction period in the construction process are effectively solved, and huge social benefits and economic benefits are brought to rapid development of high-speed rails, urban railways and high-grade highways.
本发明公开了一种新型架梁装备及架设方法，包括过孔梁、内导梁和落梁架，所述过孔梁上水平贯穿开设有内导孔，所述内导梁穿设于过孔梁上的内导孔，所述过孔梁与内导梁之间设有驱使过孔梁或内导梁作直线位移的动力滑轮机构；所述过孔梁上可行走提升或降落待架梁的落梁门架；所述过孔梁为特制钢箱梁。本发明的新型架梁装备及架设方法，打破了传统架梁必须使用架桥机的规律，摒弃了架桥机架梁时复杂而又危险的组装、起重、负重移动、过孔的高难度、高风险操作，有效改善了施工过程中施工安全性和施工工期的问题，对高铁、城铁及高等级公路的快速发展带来巨大的社会效益和经济效益。
