Hollow pier cap capping construction method
The invention discloses a hollow pier cap capping construction method, which belongs to the technical field of bridge construction, and comprises the following steps of: pouring a chamfer on the inner ring of the pier top of a hollow pier, reserving a depth of 10-15cm without pouring, and pre-embedding a chamfer reinforcing rib; a prefabricated cover plate with the thickness of 15 cm is laid on the chamfers, reserved steel bars are arranged on the side wall of the periphery of the prefabricated cover plate, and chamfer reinforcing ribs and pier body vertical steel bars are welded to the reserved steel bars; concrete with the thickness of 25 cm is poured on the prefabricated cover plate, the chamfer and the pier top of the hollow pier, and a pier cap bottom formwork is formed; and after the pier cap bottom formwork is cured, a pier cap reinforcement cage is bound at the top end of the pier cap bottom formwork, and then concrete is poured to form the pier cap. The chamfer is used as a mounting space of the prefabricated cover plate, the reserved steel bars on the periphery of the prefabricated cover plate are welded with the pier body vertical steel bars and the chamfer reinforcing ribs, the prefabricated cover plate is used as a support to replace the conventional bracket and bracket construction process, the construction procedures are reduced, and the safety risk of dismounting the bracket in the later period is reduced.
本发明公开一种空心墩墩帽封顶施工方法，属于桥梁建筑技术领域，包括如下步骤：空心墩的墩顶内圈浇筑倒角，预留10‑15cm的深度不进行浇筑，并预埋有倒角加强筋；将15cm厚的预制盖板铺设在倒角上，预制盖板周圈侧壁上设置预留钢筋，将倒角加强筋和墩身竖向钢筋均与预留钢筋进行焊接；在预制盖板、倒角和空心墩墩顶再浇筑25cm厚混凝土，形成墩帽底模板；墩帽底模板养护完成后，在墩帽底模板顶端绑扎墩帽钢筋笼，然后浇筑混凝土形成墩帽。本发明利用倒角作为预制盖板安装空间，预制盖板周圈的预留钢筋与墩身竖向钢筋和倒角加强筋焊接，利用预制盖板做支撑代替已往的支架、托架施工工艺，减少施工工序，降低后期拆除支架的安全风险。
