Bridge large-height-difference pavement layer cavity construction method
The invention discloses a bridge large-height-difference pavement layer cavity construction method which comprises the steps that steel bars are planted on an original bridge top plate, a concrete grating rib plate is connected, a plurality of cavities are formed in the concrete grating rib plate, and the height of the concrete grating rib plate coincides with the design longitudinal slope of a connected bridge; the cavities are filled with plastic foam plates, and the height of the plastic foam plates coincides with the designed longitudinal slope of the connecting bridge; and pouring a reinforced concrete pavement layer by taking the plastic foam plate and the concrete grating rib plate as a bottom die. According to the bridge large-height-difference pavement layer cavity construction method, on the premise that bridge large-height-difference connection is needed, plastic foam plates are adopted for adjustment, reinforced concrete is adopted for guaranteeing the strength of a leveling layer, the weight of the leveling layer is reduced, it is guaranteed that longitudinal slopes of two bridges coincide in design, and the influence on bridge structure design safety is reduced.
本发明公开的一种桥梁大高差铺装层空腔施工的方法，包括步骤：在原桥梁顶板进行植筋，连接混凝土格栅肋板，所述混凝土格栅肋板内部形成多个空腔，所述混凝土格栅肋板的高度与连接桥梁设计纵坡重合；于多个所述空腔内填充塑料泡沫板，所述塑料泡沫板的高度与连接桥梁设计纵坡重合；以所述塑料泡沫板和所述混凝土格栅肋板为底模，浇筑钢筋混凝土铺装层。本发明提供一种桥梁大高差铺装层空腔施工的方法，在需要桥梁大高差连接的前提下，采用塑料泡沫板进行调整，采用钢筋混凝土保证调平层强度，减轻调平层重量，保证两座桥梁设计纵坡重合，降低对桥梁结构设计安全影响。
