Method for dismantling on-arch temporary support of large-span bridge
The invention relates to a bridge, and particularly relates to a method for dismantling an on-arch temporary support of a large-span bridge. The method comprises the following steps: A, arranging a first mobile crane and a second mobile crane on the bridge surface of a bridge; B, connecting a steel wire rope of a cable crane with a temporary support; C, longitudinally moving the cable crane to a cap beam on the upper portion of an on-arch stand column; D, putting down the steel wire ropes of the first mobile crane and the second mobile crane and connecting with the temporary support; E, putting down the steel wire rope of the cable crane from the front end of the cap beam to be connected with the temporary support, making the cable crane continue to move forwards, and completing one-time gear penetrating operation; and F, repeating the step D and the step E, completing longitudinal movement of the temporary support on the lower portion of a continuous steel box girder till that the temporary support completes crotch penetrating work of all the cap beams, and completing dismantling of all the temporary supports. The method solves a problem that the temporary support on the arch of the bridge cannot be dismantled vertically, and the temporary support on the arch can be dismantled rapidly and effectively.
本发明涉及桥梁，特别是一种大跨度桥梁的拱上临时支架拆除方法。包括如下步骤：A、在桥梁的桥面设置第一移动式起重机和第二移动式起重机；B、将缆索起重机的钢丝绳与临时支架连接；C纵向移动缆索起重机至拱上立柱上部的帽梁处；D、第一移动式起重机起和第二移动式起重机的钢丝绳分别下放并与临时支架连接；E、缆索起重机的钢丝绳从帽梁的前端下放与临时支架连接，缆索起重机继续前行，完成一次穿档作业；F、重复步骤D和步骤E，完成临时支架在连续钢箱梁下部的纵向移动，直至临时支架完成所有帽梁的穿裆工作，完成所有临时支架的拆除。本发明解决了桥梁的拱上临时支架无法直上直下拆除的难题，能快速、有效的拆除拱上临时支架。
