Description

Technical Field

[0001] This invention relates to the field of building platform drainage technology, and more specifically, to a waterproof drainage structure for a building platform. Background Technology

[0002] In recent years, with economic development and accelerated urbanization, urban buildings have been increasingly developing towards high-rise structures to address the problems of urban population growth and the growing scarcity of land resources. The rooftop of these buildings is typically a single plane, requiring numerous floor drains to ensure rainwater can drain into the sewer system during rainy days.

[0003] However, because the floor drain is flush with the ground, a lot of dust and debris accumulates on its surface when it is not in use, causing it to become clogged when needed. Therefore, it is necessary to clean the floor drain regularly to ensure it flows smoothly. Furthermore, because rainwater is prone to seepage on the platform, multiple waterproof layers are usually laid on it. However, current waterproof layers cannot provide good seepage prevention, and once water seeps in, it can only continue to seep downwards and cannot drain away.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention
