Method for erecting construction of first hole beam
The invention discloses a first hole beam erection construction method, which comprises the following steps of: hoisting a 2 # section beam, a 3 # section beam and a 0 # section beam by using a 1 # section beam, and longitudinally moving the 0 # section beam to a second preset position of a pier top by using a chain block in cooperation with a crown block; a jack and a temporary cushion block are arranged at the bottom of the beam, the crown block moves the rear end of the 0 # section beam to the jack, and a crown block lifting appliance is removed; gradually pushing the 0 # section beam to the front side to a third preset position by using a jack and a temporary cushion block; a support is installed at the bottom of the 0 # segment beam, fine adjustment is conducted on the 0 # segment beam, and after fine adjustment is completed, an anchoring mechanism is installed for anchoring; hanging other segmental beams; the method comprises the following steps of: performing trial splicing on the segmental beams, performing formal splicing on the segmental beams after the trial splicing is completed, and performing glue splicing, temporary tensioning, prestress tensioning, unloading, grouting and anchor sealing treatment on the adjacent segmental beams in sequence after the formal splicing is completed. The first hole beam erecting construction method can greatly shorten the construction period.
本发明公开了一种首孔梁架设施工的方法，方法包括1’#节段梁吊装2’#节段梁3’#节段梁以及0#节段梁，使用倒链，配合天车将0#节段纵移至墩顶第二预定位置；在梁底设置千斤顶及临时垫块，天车移动0#节段梁后端至千斤顶上，解除天车吊具；利用千斤顶及临时垫块逐步向前侧推动0#节段梁至第三预定位置；在0#节段梁底部安装支座，并对0#节段梁进行精调，精调完成后，安装锚固机构进行锚固；吊挂其它节段梁；对节段梁进行试拼，试拼完成后，再对节段梁进行正式拼装，正式拼装完成后，再对相邻的节段梁依次进行胶拼、临时张拉、预应力张拉、卸载、压浆以及封锚处理。本发明首孔梁架设施工的方法能够大幅度缩短施工工期。
