Construction technology of turnout continuous beam
The invention relates to the technical field of turnout continuous beams, in particular to a construction technology of a turnout continuous beam. The construction method comprises the following steps: 1, constructing a bearing padstone and a support: constructing the bearing padstone; mounting a support; taking a bridge climbing measure; anti-shock beam falling measures are taken; 2, erecting a bracket: constructing a bracket system; foundation treatment; 3, pre-pressing the bracket, wherein a pre-pressing method is adopted; arranging a measuring point and a pre-pressing block; loading and unloading the method; an observation step; 4, formwork installation: formwork construction; mounting a template; 5, reinforcing steel bar construction: reinforcing steel bars are bound; sixthly, prestressed pipelines and steel beams are installed, wherein the pipelines are installed; mounting a steel beam; 7, concrete construction, wherein concrete pouring is conducted; and concrete curing. The position of the prestressed pipeline is fixed through the positioning steel bars, the positioning steel bars are firmly welded to the steel bar framework, it is guaranteed that the position of the pipeline is not changed, the distance between the linear sections of the positioning steel bars is 0.5 m, and the distance between the linear sections of the positioning steel bars can be properly increased to 0.3 m at the bent sections. Double control is adopted for prestress tensioning, and double control measures are adopted for steel beam tensioning, so that the engineering quality is guaranteed.
本发明涉及道岔连续梁技术领域，具体为一种道岔连续梁的施工工艺。步骤包括：一、支承垫石、支座施工：支承垫石施工；支座安装；上桥措施；防震落梁措施；二、支架搭设：支架体系；地基处理；三、支架预压：预压方法；测点及预压块布置；加载、卸载方法；观测步骤；四、模板安装：模板构造；模板安装；五、钢筋施工：钢筋绑扎；六、预应力管道及钢束安装：管道安装；钢束安装；七、混凝土施工：混凝土浇筑；混凝土养护。本发明预应力管道位置用定位钢筋固定，定位钢筋牢固焊接在钢筋骨架上，保证管道位置不变，定位筋直线段间距0.5m，在弯起段可适当加密至0.3m。预应力张拉采用双控，钢束张拉采用双控措施，以保证工程质量。
