Large-gradient girder erection construction method of bridge girder erection machine
The invention discloses a large-gradient girder erection construction method of a bridge girder erection machine, which is applied to single-line and double-line T-shaped girder erection of a JQJ180 type highway-railway dual-purpose bridge girder erection machine under the working condition that the gradient is not greater than 30% o, the bridge girder erection machine adopts a downhill erection and secondary hole passing mode during girder erection, and the gradient of a main girder is kept within 6% o. The method at least comprises one of the three steps of adjusting the height of the auxiliary supporting leg, adjusting the height of the front supporting leg and prolonging the length of the steel wire rope of the bridge girder erection machine hanging beam trolley. The use range of the JQJ180 type bridge girder erection machine is expanded, the use cost and the risk of replacing the bridge girder erection machine midway due to the gradient problem in the bridge girder erection process are reduced, the construction period is shortened, and the continuity before and after bridge girder erection construction is guaranteed.
本发明公开了一种架桥机大坡度架梁施工工法，应用于JQJ180型公铁两用架桥机在不大于30‰坡度工况下的单、双线T梁架设，架梁时架桥机采用下坡架设、二次过孔的方式且主梁的坡度保持在6‰以内，并且至少包括辅助支腿高度的调整步骤、前支腿高度的调整步骤和延长架桥机吊梁小车钢丝绳长度的步骤三个步骤中的一个步骤。本发明扩大了JQJ180型架桥机的使用范围，降低了架桥过程中因坡度问题而中途更换架桥机的使用成本和风险，节省了工期，保证了架桥施工前后的连续性。
