Reinforcing method for additionally arranging beam-slab structure on old stone arch bridge
The invention discloses a reinforcing method for additionally arranging a beam-slab structure on an old stone arch bridge. The method specifically comprises the following steps of rechecking the bearing capacity of a foundation structure, dismantling an original bridge deck system, treating diseases of the stone arch bridge, newly building a beam-slab bridge lower structure, hoisting a form, newlybuilding a beam slab, newly building a bridge deck system and additionally arranging a decorative plate. According to the reinforcing method, the beam slab is additionally arranged on the old stone arch bridge, necessary construction measures are adopted, the newly-built beam slab and an original arch ring do not work together, and the beam slab is the main stress component, so that the bearing capacity of the bridge is improved, and the use safety of the bridge is ensured; and compared with dismantling and reconstruction, the engineering scale is effectively reduced, the construction speed is high, the construction work amount and difficulty are reduced, the construction cost is saved, the construction period is shortened, damage to an original bridge structure is reduced, an abutment side slope is protected, the original bridge appearance is not changed, the special building of the stone arch bridge is reserved, accurate installation of the form can be achieved, rapidness and convenience are achieved, the labor intensity is reduced, and the working efficiency is effectively improved.
本发明公开了旧有石拱桥上增设梁板结构的加固方法，该方法具体包括以下步骤：基础结构承载力复核、拆除原桥桥面系、石拱桥病害处理、新建梁板桥下部结构、吊运模板、新建梁板、新建桥面系和增设装饰板；本发明在旧有石拱桥上增设梁板，采用必要的构造措施，使新建梁板与原拱圈不共同工作，梁板为主要受力构件，提高桥梁承载能力，确保桥梁的使用安全，与拆除重建相比，有效减小了工程规模，建设速度快，减小施工工程量和难度，节约造价，缩短施工工期，减小对原桥结构的破坏，保护桥台边坡，不改变原有桥梁外貌，保留石拱桥这一特色建筑，可以实现模板的精准安装，快速方便，降低了劳动强度，有效提高了工作效率。
