Bridge superstructure prefabricating and mounting method for road engineering
The invention discloses a bridge superstructure prefabricating and mounting method for road engineering. The bridge superstructure prefabricating and mounting method for the road engineering comprisesthe following steps: S1, firstly, site hardening and pedestal base treatment are performed, and the manufacturing work of a pedestal is completed; S2, then hollow steel formworks are transported to the site, then trial splicing and grinding treatment are conducted, and after that, the steel formworks are numbered and classified through water-soluble pigment; S3, bottom plate reinforcing steel bars and webs are installed in a binding mode; S4, after the bottom plate reinforcing steel bars and the webs are bound, the formworks are installed; S5, after the formworks are installed, manufacturingand mounting work of a corrugated pipe is performed, namely firstly mounting the bottom and then mounting the upper portion according to the sequence from bottom to top, and a sleeve is adopted at a joint; and S6, after the corrugated pipe is installed, concrete is poured in a continuous mode of horizontal layering and oblique segmentation. The water-soluble pigment is used for numbering and classifying the steel formworks in advance, and therefore the problem that the splicing quality is affected due to staggered splicing in later construction is effectively solved.
本发明公开了一种道路工程的桥梁上部构造预制安装方法，包括以下步骤：S1：首先进行场地硬化和台座基底处理，并完成台座的制作工作；S2：之后将空心钢模板运到现场，然后进行试拼、打磨处理，完毕后采用水溶性颜料对钢膜板进行编号分类；S3：采用绑扎的方式完成底板钢筋和腹板的安装工作；S4：待底板钢筋及腹板绑扎好后，进行模板安装；S5：模版安装完毕后，进行波纹管的制作和安装工作：安装顺序自下而上，先安装底部，后安装上部，接头处采用套管；S6：波纹管安装完毕后，采用水平分层以及斜向分段的连续方式浇筑混凝土。预先采用水溶性颜料对钢模板进行编号分类处理，从而有效的避免了以后施工中交错拼装，影响拼装质量的问题。
