s4, the crane loosens the support of the precast concrete pavement slab (1), the precast concrete pavement slab (1) is paved on the swamp land through the buoyancy of the air bag column (2), and the assembly of one precast concrete pavement slab (1) is completed;
s5, repeating the steps S1 to S4, and assembling the next precast concrete pavement slab (1); when two precast concrete pavement boards (1) are connected, when the precast concrete pavement boards (1) to be installed are paved on a swamp land through a crane, a convex structure (11) of the precast concrete pavement boards (1) to be installed is inserted into a clamping groove (12) of another already installed precast concrete pavement board (1), so that preliminary connection is realized;
then the surface of the joint of the two precast concrete pavement boards (1) is further fixed through a flexible steel material (8), and two ends of the flexible steel material (8) are respectively fixedly connected with the two precast concrete pavement boards (1).
7. The method for installing fabricated pavement boards for marshlands according to claim 6, wherein the prefabricated concrete pavement boards (1) on the marshlands and the pavement boards on the normal pavement are also preliminarily connected by means of the buckles and the clamping grooves (12), then the surface of the joint of the two is further fixed by the flexible steel material (8), one end of the flexible steel material (8) is fixed on the pavement boards on the normal pavement, and the other end is fixed on the prefabricated concrete pavement boards (1) on the marshlands.
8. The method for installing the fabricated road boards on the marshlands according to claim 6 or 7, wherein the gyroscope sensor (6) monitors the plane information of the prefabricated concrete road boards in real time and transmits the plane information to the micro controller (4), and the micro controller (4) controls the air pump and the power supply (5) to inflate the air bag column (2) on one side lower than the plane of the set road boards by comparing the road board plane data measured by the gyroscope sensor (6) with preset plane data, and if the road surface load is excessive so that the prefabricated concrete road boards (1) incline; the distance sensor (7) monitors the relative height value of the surface of the precast concrete pavement slab (1) and the surrounding swamp ground surface in real time, and when the precast concrete pavement slab (1) floats upwards or sinks, the micro controller (4) controls the air bag column (2) to be inflated or deflated.
