Green roof structure
The invention provides a green roof structure. The green roof structure comprises a matrix layer, a filtering and water draining layer, a protecting layer and a waterproof layer from top to bottom, wherein the filtering and water draining layer is connected with a water draining tube; green plants are planted on the matrix layer; the filtering and water draining layer is arranged at the lower end of the matrix layer, and is used for filtering impurities which permeate down along with rain water from the matrix layer, and draining the filtered rainwater through the water draining tube; the protecting layer is used for isolating the waterproof layer at the lower end of the protecting layer from the water draining layer at the upper end of the protecting layer; a roof is isolated from rainwater by the waterproof layer; the filtering and water draining layer comprises a plurality of water permeable bricks which are distributed at intervals from top to bottom; holes of the water permeable bricks are gradually reduced from top to bottom; and a tube opening of the water draining tube is arranged on the bottom of the filtering and water draining layer. The water permeable bricks are arranged on the green roof structure at intervals in the vertical direction, functions of filtering the impurities and draining water are fulfilled, a filtering effect is good, water drainage amount is large, and a filtering layer and a water draining layer which are independent are omitted.
