Curve section large longitudinal slope cast-in-place concrete ramp bridge and construction method
The invention provides a curved section large longitudinal slope cast-in-place concrete ramp bridge and a construction method. The construction method mainly comprises the following construction steps: step 1, foundation treatment; secondly, a support is erected; step 3, pre-pressing the bracket; 4, constructing a bottom mold and an outer mold of the box girder; step 5, binding reinforcing steel bars; sixthly, the core mold is hoisted; 7, pouring and maintaining the box girder; and 8, the formwork and the support are dismantled. According to the curved-section large-longitudinal-slope cast-in-place concrete ramp bridge and the construction method, the technical problems of ramp bridge support erection, linear adjustment, formwork removal and the like are mainly solved, and good technical and economic benefits can be obtained when the ramp bridge is applied to actual engineering.
本发明提供了一种曲线段大纵坡现浇混凝土匝道桥及施工方法，主要施工步骤包括：步骤一、地基处治；步骤二、支架搭设；步骤三、支架预压；步骤四、箱梁底模、外模施工；步骤五、钢筋绑扎；步骤六、芯模吊装；步骤七、箱梁浇筑及养护；步骤八、模板及支架拆除。本发明涉及的一种曲线段大纵坡现浇混凝土匝道桥及施工方法，重点解决匝道桥支架搭设、线型调整、模板拆除等技术难题，应用于实际工程中可取得较好的技术和经济效益。
