Segmented pushing and sliding construction method for large-span hyperbolic steel connecting bridge crossing urban main road
The invention discloses a segmented pushing and sliding construction method for a large-span hyperbolic steel connecting bridge crossing an urban main road, and the method comprises the steps: installing a plurality of supporting columns on the ground, and enabling the supporting columns to be arranged on the two opposite sides of the urban main road; a large-span operation platform is arranged on the multiple supporting columns; the large-span hyperbolic steel connecting bridge is divided into two side span sections and a middle span section in the length direction; a sliding rail arranged in the length direction of the large-span operation platform is laid on the large-span operation platform; a plurality of subsection units of the middle section of one span are sequentially spliced at one end of the large-span operation platform, and after each subsection unit is spliced, the subsection units are pushed and slide to the construction positions corresponding to the subsection units through the sliding rails; after the middle section of the first span is in place, a side span section is assembled on the large-span operation platform; and connecting the side span section to the end part of the middle span section and the main body structure. According to the construction method, the problems that safety accidents are likely to happen and traffic jams are caused by a conventional method for constructing the steel connecting bridge on the urban main road are solved.
本发明公开了一种跨城市主干道的大跨度双曲钢连桥分段顶推滑移施工方法，于地面安装多根支撑柱，多根支撑柱设置于城市主干道的相对两侧；于多根支撑柱上大跨度操作平台；将大跨度双曲钢连桥沿长度方向划分两边跨段和一跨中段；于大跨度操作平台上铺设沿大跨度操作平台的长度方向设置的滑轨；于大跨度操作平台的一端依次拼装一跨中段的多个分段单元，并在每拼装好一分段单元后通过滑轨顶推滑移至分段单元对应的施工位置上；在一跨中段就位后，于大跨度操作平台上拼装边跨段；将边跨段连接于一跨中段的端部和主体结构。本发明解决了在城市主干道上施工钢连桥的常规做法容易发生安全事故、造成交通拥堵的问题。
