9. A method of laying a water-logging-preventing reinforced subgrade pavement structure according to any one of claims 1-8, characterized in that the subgrade pavement structure comprises the following working steps:

s1, when the pavement is carried out, punching equipment is used for punching the top of a cement top layer (7), so that a water filtering hole (8) is positioned at the top of a drainage groove (5), in rainy days, rainwater easily infiltrates from an asphalt layer (9), the rainwater permeates the cement top layer (7) with the water filtering hole (8), then the rainwater passes through a reinforcing steel bar layer (6), the gap between the reinforcing steel bar layer (6) is large, the rainwater infiltrates downwards, the rainwater infiltrates onto the drainage groove (5) successfully, the rainwater infiltration can be completed rapidly, the drainage groove (5) discharges the rainwater from two sides of a road surface, the mud layer (1) at the bottom side of the road surface is difficult to run off, the road surface is difficult to collapse, the road surface is paved layer by layer, the strength of the road surface is improved, and in case that the top layer is damaged, the maintenance is also convenient;

s2, when a vehicle runs on a road surface, the stress point of the road surface is always stressed suddenly, at the moment, the stress point is stressed to enable the road surface stress point to slightly move downwards, the downward movement of the road surface triggers the top contact block (21), the top contact block (21) moves to drive the first fixed plate (18) to move, the first fixed plate (18) moves to drive the first inclined block (19) to move, the inclined surface of the first inclined block (19) is contacted with the inclined surface of the second inclined block (15), the inclined surfaces with larger gradients are contacted with each other, so that the pressure applied to the cement bottom layer (3) is buffered, and when the road surface is subjected to the pressure bearing of the cart, the road surface is subjected to a certain buffer protection effect, so that the road surface is not easy to be damaged due to overstressed;

s3, the internal heating block (22) is electrified through the cable (27) outside, when snow is accumulated in rainy days, the cable (27) is electrified to enable the heating wire (26) to generate heat, the heat is transferred to the heat conducting fin (25) through the heat transfer block (23) and the heat transfer rod (24), the heat conducting fin (25) transfers the heat to the asphalt layer (9), the temperature of the asphalt layer (9) is increased, and therefore melting of the snow on a road surface is accelerated, and the road surface is easier to recover to normal use in winter;

s4, when maintenance personnel maintain the pavement, electric drills can be used for being embedded into the rotating blocks (31), the rotating blocks (31) rotate to drive the threaded rods (32) to rotate, the threaded rods (32) rotate to drive the transmission plates (34) to move, the transmission plates (34) slide on the sliding rods (33), the transmission plates (34) move to drive the scrapers (35) to move, the scrapers (35) move to enable dirt accumulated in the drainage grooves (5) to be removed, so that the drainage function is not affected, and the pavement structure is convenient to maintain.

10. The method for laying a water accumulation preventing reinforced roadbed pavement structure according to claim 9, wherein in the step S2, the method further comprises the steps of:

s21, the slope of the bottom side of the first inclined block (19) is larger, the slope of the top side of the second inclined block (15) is larger, when buffering, the two inclined surfaces with larger slopes are contacted, and then when restoring, the inclined surfaces with small slopes are contacted.
