[0002] When constructing a bathroom, the waterproofing and drainage of the bathroom is the focus of the construction. In general, a floor drain is set above the drain pipe in the bathroom. The water in the bathroom is collected into the drain pipe through the slope setting of the ground. However, there is a large amount of water in the daily use of the bathroom, and the water source penetrates into the mortar layer through the gaps in the tiles. Over time, the waterproof layer will be soaked in water for a long time, which will affect its service life. In addition, the water in the mortar layer makes it impossible to drain the water source, causing the adverse effects of moisture return on the wooden door and the wall at the door. Therefore, it is necessary to design the secondary drainage at the bathroom floor drain in a targeted manner. Utility Model Content
