Example 3:

in the embodiment, as shown in fig. 1 to 10, a vertical drainage structure arranged in the middle of a downcomer 1 on the same layer is disclosed, and specifically, a pipe body 2 is provided with an upper opening and a lower opening, namely an upper connector 2.1 and a lower connector 2.2, for connecting the downcomer 1.

The pipe body 2 is provided with a plurality of overflow ports 3 along the circumferential direction, so that accumulated water in the lateral direction can enter the pipe body 2 from the overflow ports 3, and then enter the sewer pipe 1 to be discharged. Because body 2 in this embodiment sets up in cement mortar in situ, on the waterproof layer that has laid, and overflow mouth 3 just in time laminates at the waterproof layer for it can discharge smoothly to pile up ponding in the waterproof layer. Because cement mortar can block up overflow mouth 3 when laying to it influences the inside rivers of body 2 wherein to enter, then usually can be equipped with the putty on its opening, and get rid of after the test water-proof effects.

But in order to overcome above-mentioned cement mortar or silt entering influence body 2 in the normal problem that passes through of rivers, simultaneously in order to satisfy the test to the waterproof layer, thereby this embodiment is through being equipped with the removable putty of taking out from the opening in body 2 inside and realizing the effect of preventing silt.

When the drainage device is installed, each plugging strip 6 is plugged from the drainage cavity 3.2 from the lower port 2.2 by hand, so that the hollow part 6.1 can be smoothly inserted into the expansion cavity 3.1. Because the hollow area in the hollow core part 6.1 has larger volume and thinner inner wall, the hollow core part has higher compressible deformation amount and is easy to be directly plugged.

Meanwhile, in order to further improve the blocking and sealing effect of the hollow core part 6.1 in the embodiment, a protruding structure is arranged on the outer surface of the hollow core part 6.1, when the blocking strip 6 is blocked and the position of the hollow core part 6.1 cannot be adjusted inside, the protruding structure is held by hands from the outside of the overflow port 3 and pulled outwards, so that the end surface of the protruding structure completely covers the opening part of the overflow port 3, and the installation efficiency can be improved as much as possible in the actual assembly process.
