The invention discloses a modular
assembly type bridge structure, and relates to the technical field of
assembly type bridges, the modular
assembly type bridge structure is formed by splicing more than two prefabricated assembly units, each prefabricated assembly unit comprises a pavement slab, a bridge
pier and a
protection mechanism, the pavement slab is arranged at the top of the bridge
pier, a fixed base is fixedly arranged on the bridge
pier, and an annular groove is formed in the side wall of the fixed base; the buffer module comprises a protection frame, the protection frame is rotationally connected into the annular groove, a power generation module is arranged at the bottom of the fixed base, and a
visual detection module is arranged at the top of the fixed base. The navigation condition of ships in a river channel can be monitored in real time through the arranged
visual detection module, when it is detected that no ship exists in the river channel or the course of the ship does not collide with a pier, the power generation module can generate power and store energy through
water flow, and when it is detected that the course of the ship collides with the pier, the power generation module can change the working mode to make
waves. The sailing speed of the ship is slowed down through
waves, the buffering module is matched for buffering
energy consumption, and the pier is protected against damage.
