Novel prefabricated hollow slab and hollow slab bridge construction method using same
The invention relates to a novel prefabricated hollow slab and a hollow slab bridge construction method using same, and belongs to the bridge engineering field; the novel hollow slab is an improvement of a normal hollow slab, and a bottom flange is added; a pretensioning method can be used for prefabrication of the hollow slab having a cross slab; the hollow slabs are arranged side by side on a spanning, and adjacent hollow slabs are connected through the bottom flanges; in construction of a lower connecting portion f the adjacent hollow slabs, a worker can stand on the bottom for working, thus ensuring connecting quality; the top of a hollow slab side web is an upper connecting portion, and top board concrete can be casted between adjacent upper connecting portions so as to form a novel cavity; the hollow slab is provided with the prefabricated cross slab, and transverse pre-stress can be tensioned in the full bridge cross slab; the novel prefabricated hollow slab can prevent cracking problems of a normal hollow slab bridge hinge joint.
