The invention discloses a segmental box girder land rapid transfer method. The method comprises the steps that 1, a plurality of girder segment portal brackets parallel to one another are arranged ona girder conveying channel in a channel direction at certain intervals; 2, completed beam segments are hoisted to the beam segment portal brackets through a portal crane, and each beam segment is supported through at least two beam segment portal brackets; 3, after the beam segment portal brackets bear the beam segments, a self-lifting beam transporting vehicle moves to a position below the beam segment portal brackets, and the beam segment portal brackets are lifted to be away from the ground; 4, the self-lifting beam transporting vehicle transports the beam segments to a destination for construction or transfer; and 5, the self-lifting beam transporting vehicle places the beam segment portal brackets at the destination. The number of beam segments transported by the beam transporting vehicle at a time is increased, a round trip frequency of the vehicle is effectively reduced, and time consumed by beam segment transportation is saved.
本发明公开了一种节段箱梁陆地快速转运方法,包括:步骤1:在运梁通道上沿通道方向以一定间距设置若干相互平行的梁段门式托架;步骤2:将完成的梁段通过门式起重机吊装到所述梁段门式托架上,每个梁段通过至少两个梁段门式托架支撑;步骤3:所述梁段门式托架均承载有梁段后,自起升运梁车移动到各个梁段门式托架下方,托举各个梁段门式托架离地;步骤4:自起升运梁车将所述梁段运输到进行施工或转运的目的地;步骤5:所述自起升运梁车将所述梁段门式托架放置于目的地。本发明增加了运梁车一次运输梁段的数量,有效减少车辆往返次数和节约梁段运输耗费的时间。
