Embodiment Construction

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0044] The embodiment of the present invention discloses a new type of beam erecting equipment, which is used to quickly and stably erect the beam 5 to be erected on the beam erecting hole position of the bridge pier 6 . The beam erection hole position is the position between two adjacent bridge piers 6 to be erected in the direction of bridge laying, and the bridge piers 6 to be erected are provided with supporting pad stones 7 to support the beam 5 to be erected.

[0045] refer to figure 1 , the new beam erection equipment includes a hole beam 1, an inner guide beam 2, and a falling beam door frame 3 that can walk on the hole beam 1 to lift or lower the beam 5 to be erected. The hole beam 1 is a special steel box girder, which consists of several Beam segments are spliced ​​together.

[0046]The beam length of passing beam 1 needs to be equal to the lengt...

Abstract

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.

Description

technical field [0001] The invention relates to the field of high-speed rail, urban rail and road construction, in particular to novel beam erecting equipment and erection methods for prefabricated beams of high-speed rail, urban rail and high-grade highways. Background technique [0002] With the rapid development of domestic transportation infrastructure, the construction of high-speed railways, urban railways and high-grade highways has set off an unprecedented climax. In the construction of high-speed railways, urban railways and high-grade highways, the erection of prefabricated beams is one of the most important and risky key projects. [0003] In order to save investment and shorten the construction period, the standard span of prefabricated beams for high-speed railways, urban railways and high-grade highways has been increased from 32 meters and 24 meters to 40 meters respectively, and the increase in the length and weight of prefabricated beams has made erection mo...
