A novel deck pavement structure according to claim 5, characterized in that: the lower surface of the positioning block (22) is symmetrically provided with two groove-shaped holes (221), the positioning block (22) is rotatably provided with guide wheels (222) at the groove-shaped holes (221), and the upper surface of the supporting plate (21) is provided with a sliding groove (214) which is convenient for the guide wheels (222) to abut into.

8. A novel deck pavement structure according to claim 1, wherein: the U-shaped rib (3) and the positioning block (22) are provided with a fastening assembly (6) together, and the fastening assembly (6) comprises an abutting plate (61) and a fastening bolt (62); the abutting plates (61) are arranged at two ends of the U-shaped rib (3) in the length direction, and the fastening bolts (62) are used for fixedly connecting the abutting plates (61) and the positioning blocks (22).

9. A novel deck pavement structure according to claim 8, wherein: the upper surface of the positioning block (22) is provided with an adaptation groove (223), and the abutting plate (61) is located in the adaptation groove (223).

10. A novel bridge deck pavement structure construction method according to any one of claims 1 to 9, wherein: the method comprises the following construction steps: s100, laying an elevation belt: the extending strips (12) of the comb plate (1) are abutted into the preformed grooves (121) of the symmetrical comb plate (1), so that the mutually symmetrical extending strips (12) are abutted in a staggered mode, and the mutually symmetrical comb plate (1) are connected into a whole; the connecting column (41) sequentially penetrates through all the abdicating holes (122), so that all the adjacent extending strips (12) are connected into a whole, and the adjacent fixed side plates (11) are tightly abutted; finally, fixedly connecting the fixed side plates (11) and the foundation through connecting bolts (111) to enable all the comb plates (1) to be fixedly connected into a whole to form an elevation belt to serve as a construction reference belt of the bridge deck pavement layer; s200, mounting a U-shaped rib (3): the guide wheel (222) is abutted into the sliding groove (214), the outer connecting plate (72) is abutted into the guide groove (711), and the position of the positioning block (22) on the support plate (21) is quickly adjusted through displacement of the guide wheel (222) in the sliding groove (214); after the distance between two adjacent positioning blocks (22) is determined according to the scale marks (215), a locking bolt (73) is used for fixedly connecting a limiting strip (71) and an external connecting plate (72) so as to limit the positions of the positioning blocks (22) and U-shaped ribs (3) on a supporting plate (21); s300, pouring concrete: pouring concrete at the position of the U-shaped rib (3), and controlling the pouring height of the concrete to be flush with the upper surface of the comb plate (1), so that a bridge deck pavement layer with uniform texture and flat top is formed.
