Concrete pouring construction method of cast-in-place box girder
The invention provides a concrete pouring construction method of a cast-in-place box girder. The method comprises the following steps: S001, dividing a box girder between every two adjacent pier columns in a designated area into a plurality of pouring stages in the longitudinal direction of the box girder, wherein the butt joint faces of every two adjacent pouring sections are obliquely arranged;S002, conducting pouring sequentially from the far end to the near end of a constructed girder section according to the multiple divided pouring sections; S003, when pouring is conducted to the end close to the near end of the constructed beam section, conducting the pouring of the pouring section reversely; S004, combining the pouring section poured at the far end of the constructed beam sectionwith the pouring section poured at the near end of the constructed beam section; and S005, circularly carrying out the steps S002 to S004 till pouring of the box girder in the designated area is completed. The box girder formed by pouring through the method meets the stress requirement, cracking of a box girder body is reduced, and then the stability of the box girder structure is improved.
本申请提供一种现浇箱梁的混凝土浇筑施工方法，其包括以下步骤：S001、将指定区域中相邻两个墩柱之间的箱梁沿其纵向划分为多个浇筑阶段，相邻两个浇筑节段的对接面斜向设置：S002、从已施工梁段远端朝近端根据所划分的多个浇筑节段依次浇筑；S003、在浇筑到靠近已施工梁段近端的端头时，反向进行浇筑节段的浇筑；S004、由已施工梁段远端浇筑的浇筑节段与近端浇筑浇筑节段合龙；S005、循环按照步骤S002～S004，直至完成所述指定区域的箱梁的浇筑。采用该方法所浇筑成型的箱梁符合应力需求，减少箱梁梁体的开裂，继而提高箱梁结构的稳定性。
