Railway sound barrier beam bridge deck slab underlying type support cast-in-place construction method
The invention relates to railway sound barrier construction, in particular to a railway sound barrier beam bridge deck slab lower supporting type support cast-in-place construction method. Comprising the following steps: (1) measuring the placement position of a supporting structure; (2) mounting a supporting structure; (3) erecting a template; (4) leveling the template; (5) pouring bridge floor fiber concrete; (6) removing the template; (7) maintaining and tensioning; the method is simple and convenient in process and easy to operate, the work amount of high-altitude operation is reduced, and the construction operation safety is high. The position advantages of original precast beam body reinforcing steel bars and precast beam body concrete structures are fully utilized as supporting and fixing ends, so that the investment of manpower, machines and materials is reduced, and the construction cost is reduced; construction operation is flexible, the space utilization rate is high, and cross operation construction such as on-bridge and down-bridge transportation and girder erection is not affected.
本发明涉及铁路声屏障施工，具体涉及一种铁路声屏障梁桥面板下托式支撑现浇施工方法；包括以下步骤：（1）测量支撑结构安放位置；（2）安装支撑结构；（3）模板支设；（4）模板调平；（5）桥面纤维混凝土浇筑；（6）模板拆除；（7）养护及张拉；本发明方法工艺简便，易于操作，减少高空作业工程量，施工作业安全性高。充分利用原预制梁体本身钢筋的位置优势以及预制梁体混凝土结构做支撑固定端，减少人、机、料的投入，降低施工成本；施工操作灵活，空间利用率高，不影响桥上桥下运、架梁等交叉作业施工。
