Preferably, the second drainage structure is a waterproof strip 10, the waterproof strip 10 is arranged along the extending direction of the connecting gap, and the connecting gap is covered by the waterproof strip 10.

As shown in fig. 6, as an embodiment of the present invention, in installation, the waterproof sheet 1 having the drainage ditches 4 on both sides is tightly paved on a bearing wall or a bearing object, the waterproof strips 10 (the waterproof strips 10 may be waterproof sheets or waterproof rolls) which are wider than the two rows of the drainage ditches 4 and at least have no surface infiltration on the lower surfaces are paved on the adjacent drainage ditches 4, so as to completely cover the two rows of the drainage ditches 4, and the lower surfaces on both sides of the waterproof strips 10 are tightly attached to the upper surfaces of the waterproof sheets 1 on the inner side walls of the drainage ditches 4 as much as possible or are properly sealed to prevent water from rapidly flowing into the drainage ditches 4, thereby reducing the drainage task of the drainage ditches 4 at the joints of the two waterproof. In order to improve the waterproof effect, the upper surface of the waterproof board 1 on the inner side wall of the drainage ditch 4 and the lower surfaces of the two sides of the waterproof strip 10 can be processed into non-wetting surfaces 7, or more surfaces can be processed into the non-wetting surfaces 7, and the non-wetting surfaces 7 are tightly attached to each other to better prevent water flow from entering the drainage ditch 4.

Furthermore, in order to improve the waterproof effect, non-wetting materials with non-wetting surfaces such as rubber, plastic, fiber, fabric, sponge and plastic foam can be filled between the non-wetting upper surfaces of the inner side walls of the two adjacent rows of ditches 4 and the non-wetting lower surfaces of the two sides of the waterproof strip 10, so that the non-wetting upper surfaces of the inner side walls of the drainage ditch 4 and the non-wetting lower surfaces of the two sides of the waterproof strip 10 are better attached to each other and water flow and silt are prevented from entering the drainage ditch 4.

When only one drainage ditch 4 is arranged at the joint of two adjacent waterproof boards 1, the waterproof strip 10 is wider than one drainage ditch 4 and can completely cover the drainage ditch 4.

Preferably, in order to improve the waterproof effect, the portions of the waterproof strip 10 corresponding to the connecting gaps may be higher than the two sides of the waterproof strip 10, and slopes with the middle portion higher and lower are formed, so that water flow cannot spread from one waterproof board 1 to another adjacent waterproof board 1 along the lower surface of the waterproof strip 10, or from both ends of the waterproof strip 10 to the outside of the waterproof board 1.

As one of the embodiments, when two drainage ditches 4 are provided at the connection of two waterproof boards 1, the outer side wall of the drainage ditch 4 may be made taller than the inner side wall, so that the portions of the waterproof strips 10 corresponding to the connection gaps are higher than the two sides of the waterproof strips 10, thereby preventing water from flowing from the two sides of the upper surface of the waterproof strips 10 to the middle.

As one of this embodiment, when there are two escape canals 4 in the junction of two flashing 1, must not make escape canal 4 lateral wall be less than the inside wall to make the waterproof strip 10 self form the pit, prevent that rivers from forming ponding and influencing water-proof effects at the upper surface of waterproof strip 10.

Preferably, the flow guide strips 20 may be a hydrophilic material. Further, in order to improve the flow guiding effect, the flow guiding strips 20 may be combined strips 25, as shown in fig. 15, in which the hydrophilic strips 23 and the hydrophobic strips 24 are spaced apart from each other, to guide the water permeating the overlapped region between the two waterproof strips 10 to the outside of the overlapped region or the drainage ditch 4.

With reference to fig. 7, based on the foregoing embodiment, the water-proof strip 10 can be replaced by a flow-guide plate 14 having a curved middle portion with a downward opening, i.e., a hydrophilic flow-guide curved surface 13 with a non-wetting zone at the top, above the connecting gap between the two water-proof plates, so that the leakage water flow cannot enter the connecting gap. Specifically, the non-infiltration belt is arranged in the middle of the flow guide curved surface (namely right above the connecting gap), and the existence of the non-infiltration belt prevents the seepage water from spreading to the middle of the flow guide curved surface and spreading to the opposite curved surface.

With reference to fig. 8, in this embodiment, the flashing strips can also be replaced by prefabricated elements 15 having a non-wetting surface, so that leakage water cannot enter the connecting gaps of adjacent flashing.

Referring to fig. 9, in this embodiment, the prefabricated member 17 may be covered with a flexible non-wetting waterproof material instead of the waterproof strip 10, so that the leakage water cannot enter the connecting gap between the adjacent waterproof boards.

Referring to fig. 10, in this embodiment, the water-proof strip 10 may be replaced by a water-proof plate 18 with two downward-opening flow-guiding curved surfaces 13 above the connecting gap between two water-proof plates, so that the leakage water cannot enter the connecting gap between adjacent water-proof plates, and the supporting capability of the water-proof plate 18 is improved. The guide plate 18 with two downward-opening guide curved surfaces 13 can also be formed by splicing two guide plates 14 with downward-opening guide curved surfaces 13.

In this embodiment, in order to improve the waterproof effect, the two end sides of the diversion plate 18 may be processed into a combination surface with separated hydrophobicity and hydrophilicity, so that water flow cannot enter the middle area of the two ends of the diversion plate 18. Furthermore, an arc-shaped diversion ring with a downward opening and at least one group of hydrophilic surfaces 11 and non-wetting surfaces 7 which are mutually spaced can be processed on the side face of the end part of the diversion curved surface 13, or an arc-shaped or V-shaped combined belt 25 with a downward opening and at least one group of hydrophilic belt 23 and non-wetting belt 24 which are mutually spaced is installed or adhered, so that the seepage water which spreads to the end part of the diversion curved surface 13 is guided to the outside of the connecting gap.

In the embodiment described above, in addition to fig. 11, in order to improve the bonding strength between the vertical wall surface and the waterproof board 1, the joint between the waterproof board 1 and the wall surface may be formed into a lower step 19, and the vertical wall surface may be embedded in the step 19 of the two waterproof boards to prevent the vertical wall surface from moving.

Referring to fig. 12, when the waterproof board 1 has vertical wall surfaces on four sides, the lower steps 19 can be formed on the periphery of the waterproof board.

In this embodiment, the step 19 with lower circumference can also be processed into the step 19 with higher circumference.

Similarly, the waterproof board 1 with the lower steps 19 processed on the periphery can be used in all use environments and conditions, and the waterproof strip 10, the guide plate 14, the prefabricated member 15, the cladding prefabricated member 17 and the guide plate 18 can be conveniently installed and fixed.

Further, in order to reduce the weight of the waterproof board, lightening holes 8 may be formed at appropriate portions of the waterproof board.
