The invention discloses a bridge construction facility which comprises a crushing feeding device. A stone feeding tank is arranged in the top surface of the crushing feeding device. The tail end of the bottom of the stone feeding tank is provided with a stone conveying chamber in a communicating way. The bottom of the stone conveying chamber is provided with a downwardly extending accommodating chamber in a communicating way. The extending tail end of the bottom of the accommodating chamber penetrates through the bottom face of the crushing feeding device. Inwardly extending oblique panels are arranged on the left side and the right side of the top of the accommodating chamber between the stone conveying chamber and the accommodating chamber. A long crushing cylinder is arranged in the space of the accommodating chamber below each oblique panel. A first transfer chamber is arranged in a position, behind the long crushing cylinders, in the crushing feeding device. A first baffle board is arranged between the first transfer chamber and the accommodating chamber. Each long crushing cylinder is internally and fixedly provided with a rotating shaft extending front and back. The bridge construction facility is simple in structure and convenient to operate, relieves the manual labor, improves the work efficiency of pouring of crushed stones, and improves the efficiency.
