Technical Field
[0001] The utility model relates to the technical field of house drainage devices, in particular to a house building drainage device. Background Art
[0002] Roof drainage is a measure to quickly drain the rain and snow water accumulated on the roof to avoid water accumulation on the roof. In construction projects, roof drainage is divided into two types: organized drainage and unorganized drainage.
[0003] However, the traditional building drainage device still has the following problems when used:
[0004] In the process of unorganized house drainage, leaves or other plastic garbage, dust, etc. may fall on the roof. During the drainage process, rainwater will carry these garbage and move to block the drain outlet and accumulate at the drain outlet.
[0005] Therefore, we make improvements to this and propose a drainage device for house buildings. Utility Model Content
