[0034] Optionally, an anti-slip groove 16 is provided on the side of the first temporary bridge board 1, the second temporary bridge board 2 and the third temporary bridge board 3 away from the bridge deck.

[0035] The installation process of a construction temporary bridge of the utility model is as follows:

[0036] Locate the front bridge deck position: mainly measure the distance between the bolt holes of the front bridge deck and the repair and construction site, and drill holes in the road surface.

[0037] Install the front temporary bridge board: Use the boom crane mounted on the construction vehicle to lower the first temporary bridge board to the bolt hole positioning point and install it by tightening the bolts.

[0038] Install the middle temporary bridge board: Use the boom crane mounted on the construction vehicle to place the second middle temporary bridge board to the construction point that needs to be covered.

[0039] Install the rear bridge board: Use the boom crane mounted on the construction vehicle to place the third bridge board on the other side of the second bridge board.

[0040] Install the telescopic slider: drill a hole in the telescopic track hole of the third temporary bridge plate to reserve a positioning and fixing hole on the bridge deck on that side, place the slider in the telescopic track hole of the rear temporary bridge plate, and use bolts to pass through the hole on the telescopic slider and connect it to the positioning and fixing hole of the bridge deck.

[0041] Connect the front, middle and rear sidewalk boards: place the connecting blocks at the connection between the first, second and third sidewalk boards and insert the connecting pins to connect the whole, and finally level the middle sidewalk board.

[0042] The working process is to remove the connecting pins on both sides of the second temporary bridge board during daytime construction, and use the arm crane carried by the construction vehicle to lift and retract the second temporary bridge board. Workers can carry out the construction of the bridge deck road after the second temporary bridge board is retracted. After stopping the construction at night, the second temporary bridge board is put back and the connecting pins are installed. After leveling, it can be opened to traffic. When the road is open to traffic, vehicles drive over the first, second, and third temporary bridge boards in turn. When the vehicle drives fast and presses on the first or second temporary bridge board, it will drive the third temporary bridge board to slide backwards. At this time, the relative movement of the telescopic track hole and the telescopic slider of the rear temporary bridge board ensures the telescopic effect at the expansion joint.
