S-plane linear guide-beam-free shunt-wound parallel pushing construction method for steel plate beam
The invention discloses an S-plane linear guide-beam-free shunt-wound parallel pushing construction method for a steel plate girder, relates to the technical field of bridge construction, and aims tosolve the problems that an existing bridge pushing construction process easily causes large transverse deviation and high construction cost of a bridge, and the method comprises the following steps that S1, the steel plate girder is assembled; S2, a pushing device is installed; S3, a first-connection steel plate beam is installed; S4, the first-connection steel plate beam is pushed; S5, a second steel plate girder is installed; S6, the second linkage steel plate beam is pushed; S7, subsequent steel plate beams are installed and pushed; and S8, beam falling and pushing device dismounting are conducted. The walking jack comprises a vertical jacking oil cylinder, a horizontal pushing oil cylinder and a deviation rectifying oil cylinder, during installation, the jacking oil cylinder is vertically upward, the pushing oil cylinder is parallel to the extending direction of a bridge, and the deviation rectifying oil cylinder is arranged in the transverse direction of the bridge. During pushing, the deviation rectifying oil cylinder is used for transversely pushing the steel plate beam to rotate so as to adapt to the S-plane linear trend. The method has the beneficial effects that transverse deviation is convenient to control, and the engineering cost is reduced.
本发明公开了一种钢板梁S平面线型无导梁分联平行顶推施工方法，涉及桥梁施工的技术领域，旨在解决现有的桥梁顶推施工工艺容易导致桥梁的横向偏位大和施工成本高的问题，其包括如下步骤：S1：拼装钢板梁；S2：安装顶推装置；S3：安装首联钢板梁；S4：顶推首联钢板梁；S5：安装第二联钢板梁；S6：顶推第二联钢板梁；S7：安装及顶推后续钢板梁；S8：落梁及拆除顶推装置。步履顶包括竖直的顶升油缸、水平的顶推油缸和纠偏油缸，安装时，顶升油缸竖直向上，顶推油缸平行于桥梁延伸方向，纠偏油缸沿着桥梁横向。顶推时，使用纠偏油缸横向顶推钢板梁转动而适应S平面线型的走向。本发明具有便于控制横向偏位，且减小工程成本的有益效果。
