Bridge

Abstract

The invention discloses a bridge. The bridge comprises multiple hollow slab bridges placed in parallel; each hollow slab bridge comprises an II-shaped hollow slab bridge main body, an upper steel plate and a lower steel plate; the upper steel plates are placed on top flanges in the length direction of the II-shaped hollow slab bridge main bodies; the lower steel plates are placed on bottom flangesin the length direction of the II-shaped hollow slab bridge main bodies; the upper end surfaces of the upper steel plates extend out of the upper parts of the top flanges; the lower end surfaces of the lower steel plates extend out of the lower parts of the bottom flanges; the upper steel plates of the two adjacent hollow slab bridges are connected with each other through first fastening pieces;the lower steel plates of the two adjacent hollow slab bridges are connected with each other through second fastening pieces; web plates of the two adjacent hollow slab bridges mutually define wet joint passages; the wet joint passages are filled with concrete slurry; slurry inlet pipes are arranged at the lower ends of the wet joint passages; and slurry outlet pipes are arranged at the upper endsof the wet joint passages. According to the bridge, hinge joints of the adjacent hollow slab bridges mutually bear forces through the fastening pieces and wet joints so that the integral force bearing performance is improved and the service life is prolonged.

Description

technical field [0001] The invention belongs to the field of bridge engineering, and in particular relates to a bridge. Background technique [0002] Prefabricated hollow slab bridges have the advantages of simple structure, low building height, convenient prefabricated installation, good structural mechanical properties, high degree of standardization, and low cost. They are widely used in bridges with medium and small spans, especially when the building height is limited. Because it can effectively reduce the height of embankment soil, it has the advantages of saving earthwork and occupying less cultivated land, and has been widely used in plain and slightly hilly areas. [0003] The transverse bridges of the hollow slabs are connected by cast-in-place concrete hinge joints, so that the slabs are connected as a whole, so that the vehicle load acting on the roadway slab can be distributed to each slab to bear, thereby significantly reducing the load on the single slab. The...

[0003] The transverse bridges of the hollow slabs are connected by cast-in-place concrete hinge joints, so that the slabs are connected as a whole, so that the vehicle load acting on the roadway slab can be distributed to each slab to bear, thereby significantly reducing the load on the single slab. Therefore, the hinge joint is the key part of the hollow slab. Once damaged,
