The invention relates to a semi-integrated type bridge
abutment bridge with multiple portions embedded with
energy absorption materials and a construction method of the semi-integrated type bridge
abutment bridge. The semi-integrated type bridge
abutment bridge comprises a main girder. The main girder is connected with a bridge abutment. The bridge abutment comprises a lower bridge abutment body arranged on the lower portion of the main girder and used for supporting the main girder and an upper bridge abutment body connected with the end of the main girder. The upper bridge abutment body is connected with one end of a connection plate, and the other end of the connection plate is connected with a bridging slab. The joint of the connection plate and the bridging slab is provided with a
corbel. The lower portions of the bridging slab, the connection plate and the
corbel are provided with miniature piles respectively. The direction of the long edges or long shafts of the miniature piles should be perpendicular to the
longitudinal deformation direction of the bridge. The
pile length and section areas of the miniature piles at different positions are different from one another. The
energy absorption materials are arranged among the bridge abutment, the miniature
pile tops and the surrounding soil. The cross section of the
energy absorption materials surrounding the miniature
pile tops is square. The energy absorption materials between the bridge abutment and the soil behind the abutment are rectangular. By means of the bridge, the stress of the connection plate, the bridging slab and the bridge abutment is improved, the stability of the soil behind the bridge abutment is guaranteed, damage to miniature pile bodies is lowered, the
longitudinal deformation ability of the bridge is not affected, and most importantly, the anti-seismic ability of the bridge is improved.
