Incremental launching construction method for curve steel box girder ramp bridge
The invention discloses a curved steel box girder ramp bridge incremental launching construction method which comprises the following steps that S1, all steel box girders are manufactured into three-dimensional segments in a factory in a matched mode, and an incremental launching platform and a track beam are erected and assembled; a pushing device is installed; steel box girder hoisting equipment is installed; s2, hoisting, mounting and adjusting the steel box girder segment, hoisting, mounting and adjusting the steel guide girder, and welding a connector of the steel guide girder and the steel box girder segment; s3, the steel box girder is pushed in a sliding mode, specifically, S31, the whole steel box girder is pushed forwards by a designed distance till a sliding block at the foremost end of the steel box girder slides out of a rail, and the sliding block at the foremost end of the steel box girder is dismounted; step S32, integrally and forwards pushing for a set distance, and sliding blocks at the front ends of the guide beams on the track beams; and S5, after the concrete beam section is poured and formed, the remaining supports are dismantled. The steel box girder is pushed in place, and the reliability of construction quality is guaranteed.
本发明公开了一种曲线钢箱梁匝道桥顶推施工方法，包括以下步骤：步骤S1、所有钢箱梁均在厂内匹配制造成立体节段，搭设拼装顶推平台和轨道梁；安装顶推装置；安装钢箱梁起吊提升设备；步骤S2、起吊安装调整钢箱梁节段，起吊安装调整钢导梁，焊接钢导梁和钢箱梁节段的接口；步骤S3、钢箱梁进行滑移顶推，具体包括：步骤S31、整体向前顶推设计距离至钢箱梁最前端滑块滑出轨道，拆除钢箱梁最前端滑块；步骤S32、整体向前顶推设定距离，导梁前端滑块上轨道梁；步骤S5、混凝土梁段浇筑成型后拆除剩余支架。本发明实现钢箱梁的顶推就位，保证施工质量的可靠性。
