Construction method of prefabricated box girder
The invention discloses a construction method of a prefabricated box girder, and relates to the technical field of box girders. A foundation pit is excavated, concrete is poured into the foundation pit to form a cushion layer, and positioning steel bars are pre-buried; angle iron is welded to the positioning steel bars, a base formwork is built between the angle iron and the cushion layer, and concrete is poured into the base formwork to form a base; laying a steel plate on the base, and welding the steel plate with the angle iron, so that the steel plate and the angle iron jointly define a containing groove; the rubber pipe is plugged into the containing groove, the axial direction of the rubber pipe is the same as the extending direction of the containing groove, and part of the rubber pipe is arranged outside the containing groove; and a box girder formwork is built outside the base, the rubber pipe is pressed into the containing groove through the box girder formwork, and concrete is poured into the box girder formwork to form the box girder. According to the construction method of the prefabricated box girder, the slurry leakage condition can be effectively prevented, the bottom of the box girder is prevented from generating a honeycomb pitted surface, the quality and attractiveness of the box girder are guaranteed, and therefore the labor and material cost generated by finished product modification is avoided.
本发明公开了一种预制箱梁的施工方法，涉及箱梁技术领域。开挖基坑，向基坑内浇筑混凝土以形成垫层，并预埋定位钢筋；在定位钢筋上焊接角铁，在角铁和垫层之间搭建底座模板，并向底座模板内浇筑混凝土以形成底座；在底座上铺设钢板，并将钢板与角铁焊接，以使钢板和角铁共同围成容置槽；将胶管塞入容置槽，其中，胶管的轴向与容置槽的延伸方向相同，部分胶管设置于容置槽外；在底座外搭建箱梁模板，利用箱梁模板将胶管压入容置槽，并向箱梁模板内浇筑混凝土以形成箱梁。本发明提供的预制箱梁的施工方法能够有效防止漏浆情况的发生，避免箱梁底部产生蜂窝麻面，保证箱梁质量和美观度，从而避免成品修饰产生的人工及材料成本。
