Next, I will explain the construction guidelines of grass planting bricks :
Subgrade excavation: according to the design requirements, the roadbed is excavated, the earthwork is cleared, and the design elevation is reached; check whether the longitudinal slope, cross slope and sidelines meet the design requirements; trim the subgrade, level the compaction and compaction, and the compaction coefficient reaches 90 % And pay attention to buried pipelines.
Base layer laying: 100% to 200mm thick grading sand and gravel mixed with 30% soil, (the maximum particle size of the crushed stone should not exceed 60mm, the minimum particle size should not exceed 0.5mm) and leveled and compacted, with a compactness of more than 80%.
Laying of screed:
The leveling layer uses medium sand, 30mm thick. The medium sand requires a certain gradation, that is, the gradation sand with a particle size of 0.3-5mm is leveled.
Surface layer laying: The surface layer is grass-planting bricks. When laying, the grass-planting bricks should be laid according to the design pattern. When laying, the grass-bricks should be laid flat and beaten securely with a rubber hammer, but the corners of the bricks must not be damaged. Then fill the holes of the planting bricks with nutrient soil, replant the grass, and sprinkle water for maintenance. The quality requirements conform to the CJJ79-98 rules for interlocking pavement construction and inspection procedures.
