The green roof is produced according to the idea of sponge city, also called as planting roof, roof greening and the like, the green roof is provided with planting matrix, and vegetation is planted on the planting matrix, so that the green roof has the functions of intercepting rainwater, reducing urban heat island effect, purifying air, improving building energy-saving effect and the like, and can effectively relieve urban flood and increase urban greening area. Although the green roof structure is more and more at present, the green roof structure tends to be complicated, and the bearing pressure of the roof is increased. And the water storage and drainage plate used on the green roof is generally provided with a groove for storing water on the plate body, and redundant water flows away from the roof to increase the waterproof pressure of the roof. When no water falls in dry seasons, the vegetation on the green roof needs to be watered, and water flows into a roof drainage port through the roof or flows down along the roof, so that the waterproof pressure of the roof is increased. There is a need for a green roof that has a simple structure, high water holding capacity and that can be drained without water flow from the roof to reduce roof water resistance and weight bearing pressure.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned prior art, the utility model aims at providing a hold drain bar and contain the green roof in sponge city that holds the drain bar.

In the matrix layer, the matrix is vermiculite, perlite, rock wool, sand etc., and the particle diameter of matrix is greater than the particle diameter of the water seepage hole on the water storage and drainage plate to prevent the matrix from falling into the water storage and drainage plate. When the substrate is paved, the substrate particles with the diameter smaller than the diameter of the water seepage holes can be filtered by a screen. The substrate layer can also comprise a substrate layer with filter cotton arranged at the bottom.
Preferably, the isolation layer is a waterproof isolation layer. No matter the water is used for watering the vegetation in the rainy season or the dry season, the water flows from the water storage and drainage plate and does not pass through the roof, so that a waterproof layer is not required to be arranged. However, for the sake of safety, a waterproof insulating layer may be used to further improve the waterproof property of the green roof.
The utility model has the advantages that:
1. the utility model discloses a hold drain bar can effectively save sufficient moisture and supply green plant to grow, unnecessary water simultaneously does not flow from the roof subaerial, directly in the outlet is arranged at roof edge, has alleviateed roof waterproof pressure.
2. Inside the drain bar was held in the infiltration hole entering of the root system of plant through on the infiltration board, it can hold a large amount of root systems to hold the drain bar, still can provide moisture for the root system of plant, need not to set up root resistance layer, alleviates roof weight.
3. The utility model discloses a water inlet and inlet tube that set up on holding the drain bar cooperate the use, insert the inlet tube that another block held the drain bar with a drain bar and hold the water inlet of drain bar, have accomplished the equipment between holding the drain bar promptly, can make rivers again through a block hold the drain bar and flow into another block and hold the drain bar, make the water flow on roof become and realize the water flow in holding the drain bar.
4. Due to the arrangement of the green roof, watering is needed in general dry seasons, vegetation is fully paved on the roof, so that the watering can be carried out only on the green plant edge (namely the roof edge), the cost is high firstly, and the vegetation on the roof edge is difficult to water secondly. The water storage and drainage plate of the utility model can enable the watering to be carried out at the edge of the vegetation, and the water body can flow through the connected water storage and drainage plates, finally flows out from the water inlet pipe of the water storage and drainage plate at the most edge and flows down from the roof; or the water inlet pipe of the most marginal water storage and drainage plate is connected to a water pipe and directly drained from the drainage port of the roof. When rainwater is more in rainy season, redundant rainwater can be discharged in the same way.
5. The utility model discloses a green roof accords with the theory in sponge city completely, and simple structure effectively alleviates the roof load. Is suitable for large-scale popularization.
