One end of concrete layer is connected with each other, and the inside of described horizontal concrete layer and oblique concrete layer is provided with voided layer, institute
State horizontal concrete layer and oblique concrete layer be internally located at the surrounding of voided layer in the horizontal direction on be provided with laterally elongated
Reinforcing bar, vertically on be provided with vertical reinforcement, along the longitudinal direction on be provided with longitudinal reinforcement, and laterally elongated reinforcing bar, perpendicular
It is connected with each other by stirrup to reinforcing bar and longitudinal reinforcement, the same plane of described laterally elongated reinforcing bar and longitudinal reinforcement passes through hoop
Muscle is connected with shearing reinforcing bar, and the lower end of two described oblique concrete layers is connected with base, described oblique concrete layer
Stage casing is connected with multiple hounds, and hound is connected with base, the junction of described hound and oblique concrete layer
Lower end is connected with spring, and described spring is connected with base with one end of the junction of oblique concrete layer away from hound.
Preferably, described horizontal concrete layer and two oblique concrete layers connect into isosceles triangle shape.
Preferably, the equidistant arrangement of the quantity more than two of described hound, and hound.
Preferably, the angular range that described shearing reinforcing bar and longitudinal reinforcement are formed 45 degree to 60 degree it
Between.
Compared with prior art, the beneficial effects of the utility model are: the highway bridge of this beam-removing rib-increasing strengthening, laterally mix
Solidifying soil layer and the end to end isosceles triangle supporters that formed of two oblique concrete layers so that structure more has stability,
Voided layer makes the quality of structure slimmer and more graceful, laterally the setting of elongated reinforcing bar, vertical reinforcement, longitudinal reinforcement and shearing reinforcing bar
Put so that structure is more firm, hound plays a supportive role, spring has the effect of damping, buffering, this utility model has knot
The features such as structure is simple, sound construction, buffering effect are good.
