[0002] Roof waterproofing is a very important part of construction projects. Its purpose is to prevent rainwater from penetrating into the interior of the building, ensuring the structural safety of the building and the dryness and comfort of the internal environment. Drainage devices are a very important part of waterproofing projects. At present, most roofs are drained by excavating water outlets through the top of the roof, and the inner cavity of the water outlet is pre-buried with a water hopper to collect the liquid that flows from the roof to the water outlet. The bottom of the water hopper is connected to a water pipe to quickly discharge the liquid in the water hopper downward to achieve the drainage effect.

[0003] However, this drainage method is too simple in structure and does not have a filtering mechanism, which makes it easy for impurities or sediment in rainwater to enter the water outlet. In the long run, it will cause blockage of the water pipe, affect the normal drainage effect, and further affect the waterproofing project.

[0004] Moreover, the water drop bucket is installed in a pre-buried manner, which makes it difficult to dismantle and requires re-covering with cement. Long-term use of the water drop bucket will inevitably lead to corrosion and damage, which will affect normal use. Utility Model Content
