Demolition construction method for bridge track system of arch bridge
The invention provides an arch bridge road system dismantling construction method which is characterized in that longitudinal joint cutting treatment is carried out on a bridge hollow slab, then side plates of a bridge are dismantled through automobile hoisting equipment, transverse joint cutting is carried out on the bridge hollow slab, double guide beams are assembled and combined to the bridge, and two sets of double guide beams are assembled in total. The device is arranged at the center of a bridge, hollow slabs of the bridge are dismantled from the center to the two sides through longitudinal and transverse moving crown blocks on two sets of double guide beams, and meanwhile the hollow slabs within the coverage range of the double guide beams can be dismantled in a span-by-span decreasing mode through longitudinal and transverse moving crown blocks of the double guide beams implemented in the method. The maximum unbalance loading of the cross beam front-and-back span hollow slabs does not exceed two hollow slabs, so that the situation that after all the hollow slabs are dismantled span by span, the large unbalance loading of the cross beam front and back causes the hanging rod to be twisted, the hanging rod is deformed and damaged, and the safety risk of dismantling the bridge floor hollow slabs is increased is avoided.
本发明提供了一种拱桥桥道系拆除施工方法，其特征在于，对桥梁空心板进行纵向切缝处理，然后通过汽车吊装设备来对桥梁的边板进行拆除，再对桥梁空心板进行横向的切缝，将双导梁拼装组合到桥梁上，共拼装两套双导梁，布置在桥梁的中心处，通过两套双导梁上的纵横移动天车来对桥梁的空心板分别从中心处向两侧进行拆除，同时通过该方法中实施的双导梁纵横天车移动，能够对双导梁覆盖范围内的空心板进行逐跨递减式拆除，使得横梁前后跨空心板最大偏载不超过2块空心板，从而避免逐跨拆除所有空心板后，使得横梁前后大偏载将导致吊杆受扭，对吊杆产生变形和损坏，从而增加桥面空心板拆除的安全风险。
