[0003] However, when investigating, it is found that the existing planting roof takes large-area planting soil layer as base layer, lays filter layer at bottom to carry out seepage water filtration, and seepage water is discharged through water storage and drainage structure after filtration.

[0004] In hot season, natural precipitation is quickly discharged with water storage structure, and planting roof needs long time, frequent artificial irrigation, so maintenance cost is high, and water resource utilization rate is low.

[0005] And when long time is used, part of silt will penetrate filter water layer and enter water storage and drainage structure, the vertical height of water storage and drainage structure is small, drainage path is long, and internal water flow velocity is slow, so water storage and drainage layer is prone to be blocked.Rainfall is larger, and planting layer bottom water storage is often not discharged in time, leading to plant root rot and other phenomena.

[0006] And the traditional roof structure itself does not have water storage function, and in rainy season, bottom drain pipe is always in water outlet state, and moss is prone to be generated at the bottom of pipe opening, which affects the appearance of building, and wet slip is prone to cause safety hazard. UTILITY MODEL CONTENT

[0008] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving roof structure for energy-efficient green buildings, comprising a roof, a drainage trough at the top of the roof, two concrete shells placed inside the drainage trough, the outer walls of the two concrete shells being in contact with each other, a soil layer above the interior of each of the two concrete shells, a puncture-resistant layer below the soil layer, the outer walls of the two puncture-resistant layers being in contact with the inner walls of the two concrete shells respectively, a first filter layer detachably connected to the interior of each of the two concrete shells, a second filter layer detachably connected to the inner wall of the drainage trough below each of the two first filter layers, a water pipe embedded above the drainage trough and the two concrete shells, and a water storage cavity formed between the roof and the drainage trough.

[0009] Preferably, a flow-limiting mesh is embedded above the side of each of the two concrete shell inner walls that are far apart from each other, and the flow-limiting mesh is disposed between the water pipe and the concrete shell.

[0010] Preferably, locking blocks are provided on the sides of the two concrete shells that are close to each other, and the locking blocks are interlocked with each other in pairs.

[0011] Preferably, each of the two puncture-resistant layers has an edge support attached below it, the outer walls of the two edge supports are detachably connected to the inner walls of the two concrete shells, and the inner walls of the two edge supports are each equipped with a plurality of support rods, the tops of the plurality of support rods being attached to the bottom of the two puncture-resistant layers respectively.

[0012] Preferably, the top two sides of the drainage trough are inclined, the bottom one side of the drainage trough is connected to a drainage pipe, and the drainage pipe is connected to a water storage tank, and the top of the roof is inclined.

[0013] Beneficial effects

[0014] This utility model provides an energy-saving roof structure for energy-efficient green buildings. It has the following advantages: This energy-saving roof structure, through the combination of an open surface water storage structure with water pipes and a flow-limiting net, can collect natural rainfall and continuously irrigate the planting area, reducing the cost of irrigating roof vegetation and improving water resource utilization.

[0015] By combining drainage channels, a concrete shell, a soil layer, a puncture-resistant layer, a first filter layer, and a second filter layer, the area beneath the planting zone becomes a filtration structure. When the water content in the planting soil is too high, it can drain through the bottom, preventing root rot caused by excessive soil moisture. Furthermore, the filtration capacity of the plant roots provides initial filtration of the passing water, which is then collected and utilized through the bottom water storage structure and drainage pipes, improving the utilization rate of natural rainfall.

[0016] And by planting area below the vertical direction of water storage cavity, the planting area excess water is discharged by the longer horizontal drainage path is changed to vertical drainage, shortens the drainage path, increases the drainage flow rate reduces the accumulation of sediment, avoids the blockage of the drainage pipeline.

[0017] Independent planting groove structure makes the planting grooves connected by L-shaped connecting structure, enhances the stability of the planting grooves, resists the ability of the weather, and can be replaced in a modular manner when local damage occurs to reduce maintenance costs.
