A drain pipe is communicated with the bottom of the drainage groove of the lowermost row. The bottoms of the drainage grooves of the other two rows are communicated with connecting pipes. The bottom end of the connecting pipe is fixedly connected with a three-way adapter. The adjacent two connecting pipes and between the adjacent connecting pipe and the drain pipe are communicated through the three-way adapter. The lower end of the drain pipe is located outside the waterproof layer.

[0008] Wherein, a water collecting inclined plate is arranged at the front end of the V-shaped water collecting plate, and the end of the water collecting inclined plate facing the V-shaped water collecting plate is inclined downward.

[0009] Among them, a second installation hole is formed in the outer surface of the wall body. A fixing plate is fixedly installed at the rear end of the V-shaped water collecting plate. A through hole is formed in one surface of the fixing plate. A second expansion bolt is installed in the through hole. The second expansion bolt is clamped and matched with the second installation hole, and the V-shaped water collecting plate is fixed to the wall body through the second expansion bolt.

[0010] Among them, a fixing bracket 7 is sleeved and installed on the circumferential surfaces of the connecting pipe and the drain pipe.

[0011] Among them, water retaining platforms are uniformly installed on the front end wall surface of the waterproof layer, and the water retaining platforms are arranged obliquely downward.

[0012] The utility model has the following beneficial effects:

[0013] By arranging the V-shaped water collecting plate and the water collecting inclined plate in the utility model, the surface water accumulation in the relatively shallow waterproof layer can be evaporated and drained. However, the deep water accumulation will seep downward along the gaps between the waterproof layer materials. The V-shaped water collecting plate and the water collecting inclined plate can collect the seeped water accumulation and then discharge it through the drain holes, reducing the damage to the wall body and the waterproof layer caused by the water accumulation in the waterproof layer, and having strong practicability.

[0014] By arranging the water retaining platforms in the utility model, on the one hand, the area of direct contact between rainwater and the waterproof layer can be reduced. On the other hand, the water retaining platforms have a certain inclined surface and a large irradiated area, which is beneficial to the evaporation of water accumulation and further improves the practicability.

The V-shaped water collecting plate 3 is sequentially connected to the connecting pipe 4, the three-way adapter 14 and the drain pipe 6. Then, the waterproof layer 2 is constructed. The water retaining platform 10 is constructed outside the waterproof layer 2. On the one hand, the water retaining platform 10 can reduce the direct contact between rainwater and the waterproof layer 2. On the other hand, the rainwater retaining platform 10 has a certain inclined surface, and the irradiated area is large, which is beneficial to the evaporation of accumulated water. The accumulated water on the surface of the waterproof layer 2 is easy to evaporate and will not remain for a long time. The accumulated water deep in the waterproof layer 2 will seep downward along the material gaps of the waterproof layer 2. The V-shaped water collecting plate 3 and the water collecting inclined plate 12 can collect the seeped accumulated water and then discharge it through the drain pipe 6, reducing the damage to the wall body 1 and the waterproof layer 2 caused by the accumulated water on the waterproof layer 2.
