Temporary auxiliary supporting structure for bridge construction in civil engineering

The utility model discloses a temporary auxiliary supporting structure for bridge construction in civil engineering, relates to the technical field of bridge construction, and solves the problem that an existing temporary auxiliary supporting structure is inconvenient to adjust. A first toothed plate and a second toothed plate are slidably mounted in the two supporting seats correspondingly, a lifting plate is fixedly mounted at the top of the first toothed plate and the top of the second toothed plate, a first gear and a second gear are rotatably mounted at the top of the first support and the top of the second support correspondingly, and a third gear is mounted below the first gear. And a turntable is fixedly mounted on the outer surface of the first bracket. Through mutual cooperation of the supporting seat, the first toothed plate, the second toothed plate, the lifting plate, the first gear, the second gear, the third gear and the rotating disc, a worker can adjust the supporting height only by rotating
