Construction method for reinforcing existing arch bridge through prefabricated arch ring standard blocks
The invention discloses a construction method for reinforcing an existing arch bridge through prefabricated arch ring standard blocks. The construction method specifically comprises the following construction steps that firstly, the arch ring standard blocks are prefabricated in advance, an arch ring transverse moving pedestal is poured on an existing arch bridge skewback, and a dragging and dragging device is installed; step II, transporting the prefabricated arch ring standard blocks to a site, splicing the prefabricated arch ring standard blocks to form a large-section arch ring, further splicing the large-section arch ring by using a crane to form an arch ring narrow section, and dragging the arch ring narrow section to a specified position along a transverse moving pedestal by using a dragging device; the invention relates to the technical field of arch bridge construction. According to the construction method for reinforcing the existing arch bridge through the prefabricated arch ring standard blocks, construction is easy and convenient, the safety risk is low, economy is achieved, the prefabricated arch ring standard blocks are transported to a view field for multi-section splicing, plug pin rods are inserted into splicing assembly holes in the connecting positions, large-section installation and arch ring linear adjustment are conducted through hoisting of a crane, factory standardized prefabricated construction is easy, and the construction efficiency is improved. The construction efficiency is greatly improved, the construction cost is greatly reduced, and the economical efficiency is better.
本发明公开了一种预制拱圈标准块加固既有拱桥的施工方法，具体包括以下施工步骤：步骤Ⅰ、提前预制拱圈标准块，在既有拱桥拱座上浇筑拱圈横移台座，并安装拖拉曳引装置；步骤Ⅱ、将预制拱圈标准块运至现场，并将其进行拼装形成大段拱圈，利用吊机进一步拼装形成拱圈窄段，利用拖拉曳引装置将拱圈窄段沿横移台座拖拉至指定位置；本发明涉及拱桥施工技术领域。该预制拱圈标准块加固既有拱桥的施工方法，施工简便，安全风险低，经济节约，预制拱圈标准块运至观场进行多段拼装，并连接处的拼接装配孔插入插销棒，用吊机起吊进行大段安装及拱圈线形调整，易于工厂标准化预制施工，大大提高了施工效率，施工成本大幅降低，经济性也更好。
