Municipal bridge construction method based on precast concrete
The invention relates to the field of bridges, and provides a municipal bridge construction method based on precast concrete, comprising the following steps: step 1, mounting multiple groups of bridge support structures on the ground; each bridge supporting structure comprises a prefabricated pipe pile, a bearing platform, a prefabricated beam body and a steel beam, the prefabricated pipe pile is sunk into the ground, the bottom wall of the bearing platform is fixedly connected with the upper end of the prefabricated pipe pile, the lower end of the prefabricated bridge pier is fixedly connected to the top wall of the bearing platform, the prefabricated beam body is fixedly connected to the upper end of the prefabricated bridge pier, and the steel beam is erected on the top wall of the prefabricated beam body and fixedly connected with the prefabricated beam body. More than two limiting mechanisms are arranged on the steel beam; secondly, bridge deck structures are installed among the multiple prefabricated beam bodies; the installation bridge deck structure comprises more than two prefabricated bridge deck slabs, the prefabricated bridge deck slabs are hoisted to the top walls of the steel beams one by one, and the prefabricated bridge deck slabs which are subsequently hoisted to the top walls of the steel beams are jacked through a sliding type jacking mechanism, and 3, other bridge deck components are installed on the prefabricated bridge deck slabs. Trouble pouring and welding are not needed, and the construction efficiency is improved.
本发明涉及桥梁领域，提供了一种基于混凝土预制件的市政桥梁施工方法，包括以下步骤：步骤一：在地面上安装多组桥支撑结构；每组桥支撑结构包括预制管桩、承台、预制梁体以及钢梁，把预制管桩沉入地面内，把承台底壁和预制管桩上端固接，把预制桥墩下端固接于承台顶壁，把预制梁体固接于预制桥墩上端，预制梁体顶壁架设有钢梁，钢梁和预制梁体固接，钢梁上设有两个以上限位机构；步骤二：在多个预制梁体之间安装桥面结构；安装桥面结构包括两个以上预制桥面板，逐个把预制桥面板吊至钢梁顶壁，利用滑动式顶紧机构把后续被吊至钢梁顶壁的预制桥面板顶紧，步骤三：在预制桥面板上安装其他桥面部件。本发明无需麻烦的浇筑和焊接，提高施工效率。
