Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular to a concealed drainage channel structure. Background Technology

[0002] Traditional roof drainage systems often use exposed eaves gutters or PVC drain pipes, which have the following problems: 1. Poor aesthetics: Exposed drainage channels affect the building facade, especially clashing with modern minimalist or antique architectural styles; 2. Prone to clogging: Fallen leaves and debris can easily enter the open channels, leading to poor drainage or even backflow; 3. Difficult maintenance: Frequent cleaning of debris inside the channels is required, and high-altitude operations pose a high risk; 4. Insufficient durability: Exposed channels are susceptible to aging and cracking due to ultraviolet radiation and temperature differences. Existing improved solutions (such as embedded drainage channels) still suffer from complex structures, low drainage efficiency, and inability to cope with extreme weather. Therefore, an innovative solution that combines functionality, concealment, and reliability is urgently needed. Utility Model Content
