Construction method for encased concrete of large-span arch bridge
The invention relates to a construction method for encased concrete of a large-span arch bridge, which comprises the following steps of: dividing the encased concrete of the arch bridge into a top plate ring, a bottom plate ring and a web plate ring along the height direction, and respectively dividing the top plate ring, the bottom plate ring and the web plate ring into working surfaces with the same quantity along the longitudinal direction of the arch bridge; the top plate working face, the bottom plate working face and the web working face are divided into a plurality of working sections with the same number, the concrete volumes of the working sections at the corresponding positions of all the top plate working face, all the bottom plate working face and all the web working faces are basically equal, the concrete volume of each working section is small, the construction difficulty is smaller, and the construction efficiency is improved. And in the whole construction process, synchronous and symmetrical pouring can be achieved, corresponding working sections of the same working face are constructed firstly, all working sections of the same working face are circularly constructed, so that loading is balanced in the construction process, a main arch is evenly stressed, the construction safety is improved, and encased concrete of the stiff skeleton arch bridge can be constructed more simply and safely.
本发明涉及一种大跨拱桥外包混凝土的施工方法，通过将拱桥外包混凝土沿高度方向分成顶板环、底板环和腹板环，再将顶板环、底板环和腹板环分别沿拱桥纵向分成相等数量的工作面，以及将顶板工作面、底板工作面和腹板工作面分别分成相等数量的若干工作段，并使得所有顶板工作面、所有底板工作面和所有腹板工作面各自对应位置的工作段的混凝土方量基本相等，单个工作段的混凝土方量较小，施工难度更小，且整个施工过程均能够同步对称浇筑，先施工相同工作面的对应工作段，循环施工完相同工作面的所有工作段，使得施工过程中加载平衡，主拱均匀受力，提高了施工安全性，使得能够更加简单、安全的对劲性骨架拱桥外包混凝土进行施工。
