Box culvert floating transportation installation method

The invention relates to a box culvert floating transportation installation method, and belongs to the technical field of box culvert construction, and the box culvert floating transportation installation method comprises the following steps: installing a first air bag in a hole of a to-be-placed box culvert, and installing a second air bag on the outer side of the to-be-placed box culvert; the first anchor boat is connected with a hanging ring arranged at the front end of the to-be-placed box culvert, and the second anchor boat and the third anchor boat are correspondingly connected with hanging rings arranged at the rear end of the to-be-placed box culvert; the first anchor boat drags the to-be-placed box culvert into water, and the first anchor boat drags the to-be-placed box culvert to move towards the construction position; when the to-be-placed box culvert is conveyed to a certain distance away from the construction position in a floating mode, the first anchor boat starts to decelerate, and the to-be-p
