Incremental pushing bridge informatization monitoring method

The invention belongs to the technical field of bridge monitoring, and particularly discloses a method for informatization monitoring of a pushing bridge, which comprises the following steps: S1, after a first bridge corresponds to a second bridge, a distance measuring instrument at the bottom of the first bridge sends a distance measuring signal to a baffle at the bottom of the second bridge in real time, and the distance measuring instrument transmits the distance measuring signal to an external computer in real time; and displaying the relative distance between the first bridge and the second bridge through a computer display screen. The cushion frame drives the vertical rod to move downwards through the weight of a vehicle, the downward-moving vertical rod enables the sliding rod to adjust the pressing plate to move through rotation of the rotating plate till the opposite pressing blocks get close to each other, mud blocks in the bridge expansion joint are smashed in an extrusion mode, the situation that
