a first blocking member protruding from one side of the floor layer having the bin dividing surface to divide the floor layer into at least two drainage areas, the floor layer at each drainage area defining a drainage bin with the corresponding first blocking member;

the drainage area corresponding to each drainage bin is provided with the slope finding layer;

the floor drain pieces are arranged in each drainage area, penetrate through the slope finding layer and the floor layer, and the inlet ends of the floor drain pieces are communicated with the lowest position of one side, away from the floor layer, of the slope finding layer;

the waterproof layer is laid on one side, away from the floor layer, of the slope finding layer;

the decorative layer is laid on one side, away from the slope finding layer, of the waterproof layer.

2. The roof drainage structure and construction as claimed in claim 1 wherein the first blocking member is raised above the floor level in a direction perpendicular to the binning plane.

3. The roof drainage structure and structure as claimed in claim 1, wherein the first blocking member is a reverse threshold, and the height of the reverse threshold protruding from the bin dividing surface is 50-100 mm.

4. The roof drainage structure and structure of claim 1, wherein the waterproof layer comprises a first waterproof layer and a second waterproof layer, the first waterproof layer is laid on the slope layer, and the second waterproof layer is laid on the side of the first waterproof layer away from the slope layer.

5. The roof drainage structure and construction of claim 1 further comprising an insulation layer, wherein the insulation layer is laid between the waterproof layer and the finish coat.

6. The roof drainage structure and structure of claim 5, wherein the side of the insulation layer facing away from the waterproof layer corresponding to each drainage area has the same slope as the slope-finding layer, and the lowest part of the side of the insulation layer facing away from the waterproof layer is communicated with the inlet end of the floor drain.

7. The roof drainage structure and construction of claim 5 further comprising an insulation layer and a protective layer, wherein the insulation layer is disposed between the insulation layer and the protective layer, and the protective layer is disposed between the insulation layer and the finish layer.

8. The roof drainage structure and construction as claimed in claim 7 wherein said protective layer is provided with a telescopic through-slit extending through said protective layer in the thickness direction thereof.

9. The roof drainage structure and structure of claim 7 wherein the facing layer has a slope facing away from the protective layer, and the lowest slope of the slope facing surface has drainage channels running through the facing layer and the protective layer in the thickness direction of the facing layer and the protective layer.

10. The roof drainage structure and construction of claim 9 further comprising a second barrier member disposed on the protective layer adjacent to the drainage channel;

the extending direction of the second blocking component is parallel to the extending direction of the drainage groove, and along the thickness direction of the decorative layer and the protective layer, the surface of the second blocking component, which deviates from the protective layer, is higher than the surface of the drainage groove.
