Arch bridge encased concrete web template construction method and web template thereof
The invention relates to the technical field of arch bridge encased concrete construction, in particular to an arch bridge encased concrete variable-height curve web construction method which comprises the steps that a plurality of outer side formwork units are assembled and manufactured on the ground, and the height of the outer side formwork units is larger than the pouring height of an arch ring section web; the outer side formwork unit is cut in a matched mode at a time according to the arch rib line type; and then the outer side formwork units are hoisted to the to-be-installed position, and splicing is conducted in the longitudinal direction of the arch rib till the to-be-poured section is covered. Ground assembling is not affected by construction space, construction operation is easy, the formwork splicing quality can be improved, the flatness and attractiveness of the formed concrete surface are improved, meanwhile, the matching, cutting and scattered splicing process on an arch is reduced, the safety risk of high-altitude operation is reduced, in addition, matching and cutting are conducted on the ground according to the arch rib line type, and the construction efficiency is improved. The device can directly adapt to an arch box curve and a variable height line type, and the construction efficiency and quality of a web template are integrally improved; the invention further relates to the web formwork adopting the construction method.
本发明涉及拱桥外包混凝土施工技术领域，特别涉及一种拱桥外包混凝土变高曲线腹板施工方法，包括：于地面组拼制备若干外侧模板单元，所述外侧模板单元高度大于拱圈截面腹板浇筑高度；根据拱肋线型一次配切所述外侧模板单元；再吊运所述外侧模板单元至待安装位置，进行沿拱肋纵向的拼接，直至覆盖待浇筑段。成型大块模块，地面组装不受施工空间影响，施工操作容易，能够提高模板拼接质量，提高成型混凝土表面平整、美观度，同时，减少拱上配切散拼过程，降低高空作业安全风险，另外，大块模块在地面根据拱肋线型进行了配切，能够直接适应拱箱曲线及变高度线型，整体提升了腹板模板施工效率和质量；本发明还涉及采用上述施工方法的腹板模板。
