Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses green roof structure.

Referring to fig. 1 and 2, a green roof structure includes a roof 100 and a parapet 200, the parapet 200 being disposed along a circumferential side of the roof 100, the parapet 200 being fixedly connected to the roof 100. The roof 100 is provided with a waterproof layer 110, the waterproof layer 110 is provided with a soil layer 111, the soil layer 111 is composed of soil, and the soil layer 111 is doped with organic fertilizer. The top of soil horizon 111 is provided with drainage layer 112, and drainage layer 112 comprises drainage cloth, and drainage cloth covers on soil horizon 111, and drainage cloth and parapet 200 fixed connection. The soil layer 111 is planted with green plants 113, and the stems of the green plants 113 penetrate out of the water filtering layer 112.

Green plants 113 are grown in soil layer 111 and organic fertilizer provides nutrients for the growth of green plants 113. In rainy days, rainwater falls on the water filtering layer 112, penetrates through the water filtering layer 112 to enter the soil layer 111, so as to provide moisture for the growth of green plants 113, the waterproof layer 110 blocks the rainwater in the soil layer 111, and the rainwater is reduced from penetrating through the roof 100 to enter the room. Along with the continuous accumulation of rainfall, the rainfall volume of accumulation on drainage layer 112 continuously increases, and the rainwater crosses parapet 200 and flows the outside of roof 100, and when the rainwater flowed, drainage layer 112 blockked the soil and the fertilizer in soil horizon 111, and the condition that the reduction rainwater flow was taken away soil and fertilizer takes place, and then reaches the condition that reduces the fertilizer and run off and take place.

In order to increase the waterproof effect of the waterproof layer 110 on the roof 100, the waterproof layer 110 includes plastic cloth and asphalt waterproof paste. When the waterproof layer 110 is constructed, asphalt waterproof paste is applied to the inner side of the parapet wall 200 and the roof 100, then plastic cloth is covered on the asphalt waterproof paste, so that the plastic cloth and the asphalt waterproof paste are bonded together, and then the asphalt waterproof paste is applied to the plastic cloth. By arranging the plastic cloth between the two layers of asphalt waterproof ointments, the influence of the aging and chapping of the asphalt waterproof ointments on the waterproof effect of the waterproof layer 110 can be reduced, namely, the waterproof effect of the waterproof layer 110 on the roof 100 is increased.

During the production of the green plants 113, the roots of the green plants 113 continuously extend to the bottom of the soil layer 111; the green plants 113 may damage the waterproof layer 110 when their roots extend. In order to reduce the damage to the waterproof layer 110 caused by the growth of the green plants 113, a concrete layer 114 is disposed on the waterproof layer 110, and the concrete layer 114 is formed by solidifying concrete on the waterproof layer 110. When the root of the green plant 113 grows, the root of the green plant 113 continuously extends to the position of the concrete layer 114, and then the hardness of the concrete layer 114 is high, so that the root of the green plant 113 cannot pass through the concrete layer 114, and further the root of the green plant 113 cannot damage the waterproof layer 110.

In order to facilitate the drainage of rainwater on the roof 100 to the outside of the roof 100, the top surface of the roof 100 is disposed obliquely, the top surface of the concrete layer 114 is disposed parallel to the top surface of the roof 100, and the top surface of the soil layer 111 is disposed parallel to the top surface of the roof 100. The lower end of the roof 100 is provided with a blocking wall 120, and a drainage channel 121 is formed between the blocking wall 120 and the parapet wall 200 at the lower end of the roof 100. Two ends of the barrier wall 120 are fixedly connected with the corresponding parapet walls 200, the bottom of the barrier wall 120 is fixedly connected with the concrete layer 114, and the top surface of the barrier wall 120 is flush with the top of the soil layer 111. The parapet 200 at the lower end of the top surface of the roof 100 is provided with a drain pipe 300, the drain pipe 300 is vertically arranged, the drain pipe 300 is fixedly connected with the parapet 200, and the drain pipe 300 is communicated with the drain channel 121.

After the rainwater falls on the water filtering layer 112, the rainwater flows along the inclined direction of the water filtering layer 112, and then the rainwater passes through the blocking wall 120 and enters the drainage channel 121, and the rainwater entering the drainage channel 121 is drained out of the roof 100 through the drainage pipe 300, so that the accumulation of the rainwater on the roof 100 is reduced, and the rainwater on the roof 100 is conveniently drained out of the roof 100.

The inclination angle of the top surface of the roof 100 is 1-9 degrees, and the inclination angle of the top surface of the roof 100 is 5 degrees in this embodiment, so that the rainwater falling on the water filtering layer 112 flows along the inclination direction of the top surface of the roof 100, and on the other hand, the rainwater is reduced and the soil is driven to move to the lower end of the top surface of the roof 100 when flowing, thereby providing a stable environment for the growth of the green plants 113.

When rainwater flows along the inclined direction of the water filtering layer 112, part of the rainwater penetrates through the water filtering layer 112 and enters the soil layer 111, and the top surface of the soil layer 111 is arranged parallel to the top surface of the roof 100, so that the rainwater flows in the soil layer 111 after entering the soil layer 111; when rainwater flows in soil layer 111, it is easy to bring soil to the lower end position of the top surface of roof 100, resulting in accumulation of soil in soil layer 111 at the lower end position of the top surface of roof 100.

In order to reduce the accumulation of soil in the soil layer 111 at the lower end of the top surface of the roof 100, a plurality of mud-blocking plates 130 are arranged on the side of the blocking wall 120 facing away from the drainage channel 121, and the plurality of mud-blocking plates 130 are all vertically arranged. The multiple mud blocking plates 130 are sequentially arranged at intervals along the inclined direction of the top surface of the roof 100, two ends of each mud blocking plate 130 are fixedly connected with the corresponding parapet 200, and the bottom of each mud blocking plate 130 is fixedly connected with the top of the concrete layer 114. Each mud blocking plate 130 is located in the soil layer 111, and the top of each mud blocking plate 130 is flush with the top of the soil layer 111. When rainwater flows in the soil layer 111, the mud blocking plate 130 blocks soil in the soil layer 111, thereby reducing the occurrence of the situation that the soil in the soil layer 111 flows along with the rainwater, and further reducing the occurrence of the situation that the soil in the soil layer 111 gathers at the lower end position of the top surface of the roof 100.

On dry weather, the moisture in soil layer 111 decreases, which in turn causes the soil in soil layer 111 to solidify together; if meeting in strong wind weather, strong wind blows green plant 113, and green plant 113 destroys drainage 112 under the effect that strong wind blows and scrapes, finally makes green plant 113 drive the soil in soil horizon 111 and directly blown away from roof 100 to probably lead to causing the danger to the pedestrian.

In order to reduce the occurrence of the situation that the green plants 113 may cause danger to pedestrians, an iron wire 140 is arranged between two adjacent mud blocking plates 130, the iron wire 140 is fixedly connected with the mud blocking plates 130, and the iron wire 140 is buried in the soil layer 111. The in-process that green plant 113 grows, the root of green plant 113 constantly extends, makes then the root winding of green plant 113 at wire netting 140 to make wire netting 140 fix green plant 113, when reducing strong wind weather, green plant 113 causes the dangerous condition to take place to the pedestrian.

Referring to fig. 1 and 3, in heavy rain, the flow rate of rainwater in the sewer 500 is large, and if the rainwater continues to be discharged into the sewer 500, the rainwater in the sewer 500 overflows the road surface. In order to reduce the occurrence of the rainwater overflowing the road surface in the sewer 500, the end of the drain pipe 300 is provided with a temporary storage assembly 400, and the temporary storage assembly 400 temporarily stores the rainwater discharged from the drain pipe 300 and discharges the rainwater into the sewer 500 after the flow rate of the rainwater in the sewer 500 is reduced.
