The invention belongs to the technical field of cable-stayed bridge closure construction, and particularly relates to a large-span cable-stayed bridge jack pushing and sliding side span closure method which comprises the following steps: step 1, bridge floor hoisting: hoisting an S15 beam section through a bridge floor crane, and after connection with an S14 beam section is completed, mounting and tensioning a fifteenth pair of stay cables; according to the large-span cable-stayed bridge jack pushing and sliding side span closure method, the steps 1-7 are set, a jack pushing mechanism is adopted in a matched mode, when side span closure is carried out on a large-span cable-stayed bridge, closure height adjustment is carried out on beam sections, transverse closure adjustment is carried out on the beam sections, and longitudinal closure movement adjustment is carried out on the beam sections; and closure fine adjustment is carried out on the side span closure beam section, so that the problem that the precision, the stability and the sealing performance of interfaces of all parts of a bridge floor are difficult to control and adjust in an existing split mounting type side span closure method is solved.
本发明属于斜拉桥合龙施工技术领域，尤其是一种大跨斜拉桥千斤顶顶推滑移边跨合龙方法，包括以下步骤：步骤一、桥面吊装，通过桥面吊机吊装S15梁段，与S14梁段完成连接后，安装并张拉第15对斜拉索。该大跨斜拉桥千斤顶顶推滑移边跨合龙方法，通过设置步骤一到步骤七，并配合采用千斤顶顶推机构，在对大跨斜拉桥进行边跨合龙时，分别对梁段进行合龙高度调节和对梁段进行横向合龙调节，以及推动梁段进行纵向合龙运动调节，实现对边跨合龙梁段进行合龙精调，从而解决了现有的拼装式边跨合龙方法，存在桥面各部位接口的精度、稳定性和密封性难以控制调节的问题。
