Installation and construction method of steel arch shell with three-dimensional curved surface multi-arch-limb structure
The invention discloses a mounting construction method of a steel arch shell with a three-dimensional curved surface multi-arch-limb structure, which belongs to the technical field of bridge construction and comprises the following steps of: 1, finishing concrete pavement of upper-layer bridge floors of a main bridge and an approach bridge, and assembling crawler cranes on the upper-layer bridge floors for block hoisting after the upper-layer concrete bridge floors of the main bridge and the approach bridge are paved; 2, hoisting the end section of the side longitudinal beam; 3, sequentially installing and hoisting arch limbs and other arch ribs except two sections of arch ribs close to the arch top in the side longitudinal beams from the two sides to the middle, and installing according to the principle that temporary supports are firstly arranged and then hoisting is carried out in the installation process; 4, the vault is installed; 5, mounting the last two sections of arch ribs; and 6, unloading, and dismounting the support frame. The method comprises the following steps of: assembling crawler cranes on an upper-layer bridge surface for hoisting in blocks after paving the upper-layer concrete bridge surface of a main bridge and an approach bridge; the side longitudinal beams are sequentially installed from the two sides to the middle, the construction steps are simple, the steel arch shell is formed by matching the construction progress of arch limbs and arch ribs, and the construction period is shortened.
本发明公开了一种具有三维曲面多拱肢结构的钢拱壳的安装施工方法，属于桥梁施工技术领域，其包括：1、完成主桥及引桥上层桥面混凝土铺装，待主桥及引桥上层混凝土桥面铺装完成后，在上层桥面组装履带吊分块吊装；2、吊装边纵梁端部节段；3、由两侧向中间依次安装，吊装边纵梁中、拱肢和除去靠近拱顶的两段拱肋外的其他拱肋，在安装过程中按照先设置临时支撑后吊装的原则进行安装；4、安装拱顶；5、安装最后两段拱肋；6、卸载、支撑架拆除。本发明待主桥及引桥上层混凝土桥面铺装完成后，在上层桥面组装履带吊分块吊装；边纵梁采用从两边向中间的顺序依次安装，施工步骤简单，钢拱壳采用拱肢与拱肋的施工进度相互配合，缩短施工周期短。
