[0006] Further preferably, the compacted backfill soil layer has a thickness of 1200-1800 mm, a compaction coefficient>0.93, and the permeable brick thickness of the permeable brick layer is 10 cm.
[0007] Furthermore, the vertical height between the bottom of the planting soil and the top surface of the flat curbs on both sides is 40 to 90 mm, and the vertical height between the top surface of the rain grate and the top surface of the flat curbs on both sides is 10 to 12 mm.
[0008] Furthermore, the thickness of the sand and gravel compaction layer is 30~32cm.
[0009] In addition, the thickness of the sandless macroporous concrete layer is 18~20cm.
[0010] More preferably, the dry hard cement mortar layer has a thickness of 3-4 cm; and the permeable brick layer has a thickness of 10 cm.
[0011] Compared with the prior art, the utility model has the following characteristics and beneficial effects:
[0012] The sunken green space in this application can collect rainwater from the permeable bricks on both sides. When the amount of rainwater is too large, it can be filtered and enter the rainwater grate and then enter the drainage ditch, which significantly improves the water storage capacity of the sunken green space structure and reduces the occurrence of waterlogging in urban communities. The simple structure is conducive to promotion and can generate greater economic benefits after widespread promotion. BRIEF DESCRIPTION OF THE DRAWINGS
