Hollow thin-wall pier solid section bottom formwork construction method
The invention relates to the technical field of pier building construction, and discloses a hollow thin-wall pier solid section bottom formwork construction method. The supporting inner edge is reserved through machining of the top end of the variable cross-section section of the hollow pier, the prefabricated cover plate can be directly placed at the top end of the hollow cross section of the pier column and serves as a bottom formwork for pouring of the solid section, an embedded part does not need to be arranged at the top end of the hollow cross section any more, and the bottom formwork of the solid section does not need to be constructed in a profile steel support erecting mode any more; and therefore, the construction steps of polishing, steel bar connection and the like are avoided, and the construction period is shortened. Therefore, no extra influence is caused on the pier column, the construction cost is reduced, the safety risk of disassembling the construction support in the later period is eliminated, and the construction period is shortened.
本发明涉及桥墩建筑施工技术领域，公开了一种空心薄壁桥墩实心段底模板施工方法。本发明通过空心墩的变截面段顶端加工预留出支撑内沿，预制盖板可直接放置在墩柱空心截面顶端，充当实心段浇筑的底模板，不再需要在空心截面顶端设置预埋件，实心段底模板也无需再通过搭设型钢支架的方式进行施工，也无需利用预制板施工，从而避免打磨、钢筋连接等施工步骤，减少施工周期。因此，本发明不仅没有给墩柱造成额外的影响，降低了施工成本，还消除了后期拆卸施工支架的安全风险，节约了施工周期。
