The emergence of the grass grid just solved this problem. Moreover, grass grids are also widely used in fire exits and parking lots. The problem of increasing green space has been solved, and the ecological environment and safety have been improved. The following is an analysis of the construction and maintenance experience of the grass trellis, for the exchange and reference of peers. There are mainly the following schemes for the grass-roots structure: 1. Plain soil compaction + melon seed slices + gravel + melon seed slices + grass grid + mixed nutrient soil 2. Plain soil compaction + crushed stone + concrete foundation + melon seeds + grass grid + mixed nutrient soil 3. Plain soil compaction + crushed stone + concrete foundation + melon seeds + non-woven blanket + grass grid + mixed nutrient soil From the analysis of the construction case, we draw the following conclusions: The first scheme has smooth drainage, but after a long time, the ground is likely to collapse due to the load on the ground; the second scheme takes a long time to collect rainwater and wash away easily causing nutrient soil loss The nutrient soil in the grass trellis is reduced; after technical discussion combined with the experience of vertical greening, the third method is to increase the non-woven blanket compartment, which can prevent the nutrient soil from losing and can also play a role in water retention. Features introduction 1. Complete greening: the grass grid provides more than 95% of the grass planting area, complete greening effect, can absorb sound and dust, and obviously improves the quality and taste of the environment. (Reference: Concrete grass-planting bricks have only 30% voids) 2. Saving investment: The grass grid makes the parking and greening functions into one, which can save the developer's valuable investment in a city with a lot of money. 3. High strength and long life: The planting grid uses special materials with patented technology, and its compressive capacity is up to 200 tons/square meter, which is larger than the standard fire-fighting climbing surface 32 tons/square meter. 4. Flat and complete: the unique and stable flat-insertion lap joint of the planting grid makes the entire paving surface connected into a flat whole, avoiding partial depression, and the construction is extremely convenient. (Reference: Each piece of concrete grass planting bricks is independent, and the concrete cushion foundation must be poured to keep it level) 5. Performance stability, anti-ultraviolet, acid and alkali corrosion resistance, abrasion resistance, weather resistance -40鈩?90鈩? (Reference: Concrete grass-planting bricks are easy to crack and break during temperature changes and frost) 6. Excellent drainage: The gravel load-bearing layer provides a good water access function, which facilitates the drainage of excess precipitation. 7. Protect the lawn: The gravel load-bearing layer provides a certain water storage function, which is beneficial to the growth of the lawn, and the grass roots can grow to the gravel layer. (Reference: Concrete grass-planting bricks have only a small space, and the temperature is as high as 50 degrees in the summer sun) 8. Green and environmental protection: The planting grid is safe and stable, can be recycled and reused, absolutely no pollution, and comprehensively care for the lawn. 9. Lightweight and economical planting grids are 5 kilograms per square meter, extremely light, quick to install, saving labor and shortening the construction period. (Reference: 250 kg per square meter of concrete grass bricks) 10. Common size: 500mm*500mm*38mm 500mm*500mm*48mm 500*500mm*68mm Architectural features 1.

Rainwater leaks naturally, soil quality is not lost, and there is no water accumulation. Basic treatment Grass-grass grid base treatment for parking spaces: 1. The foundation soil should be compacted in layers, and the compactness should reach 85% or more; if it belongs to the soft plastic-flow plastic silt layer, it is recommended to fill with blocks and compact to compaction. 2. Set up 150 thick sand and gravel cushion. The specific method is: 10% of medium coarse sand, 60% of 20-40 particle size crushed stone, 30% of cohesive soil, mix and mix well, flatten and roll until compact. 3. Set up a 60-thick stable layer (also serving as a planting layer). The stabilizing layer is: 25% gravel with a particle size of 10-30, 15% medium-coarse river sand, 60% farming soil and mixed with appropriate amount of organic fertilizer. The three are mixed evenly and spread on the sand-stone cushion. Compacted and compacted, it can be used as the base of grass planting grid. 4. Sprinkle planting soil in the recessed planting trough of the grass-planting grid and sweep it evenly into the grass-planting grid holes with a broom. The height of the soil layer should be 5-10mm below the level of the grass-planting grid. 5. Spread sod or sowing grass on the planting soil layer of the grass grid. When laying turf, compact the turf on the planting soil. Watering and curing can stop after the grass survives. 6. Sprinkle a little organic fertilizer on the grass roots, and pave the grass trellis manually. The external dimensions of the grass planting grid are designed according to the size modulus of the parking space, and generally do not need to be cut when paving; when the parking space has special shape requirements or the parking space has a sewage manhole cover, the grass planting grid can be cut to suit different parking spaces The shape requirements. Grass lattice base treatment for fire lanes: 1. Pave grass grids on the fire lane, and the compactness of the foundation soil should meet the design requirements of general concrete fire lanes. 2. The method of crushed stone cushion and stone powder stabilization layer of fire lane is also the same as the design requirements of ordinary concrete fire lane. 3. Make an 80-thick layer of planting soil on the stone powder stabilized layer. The soil layer method is: 30% gravel with a particle size of 10-30, 15% medium-coarse river sand, 55% farming soil and mixed with appropriate amount of organic fertilizer. The three are mixed evenly and spread on the compacted stone powder On the stable layer, compacted and compacted, it can be used as the base layer of the grass grid. 4. Pave the grass planting grid and planting grass on the grass planting grid base. 5. It is worth noting that if the fire lane is used as the main passage for vehicles in ordinary times, because the vehicles travel frequently and the speed is relatively fast, this is not good for the use of grass grids and the normal growth of turf, but affects the greening rate and beauty. Under circumstances, we recommend that the main vehicle traffic roads still adopt concrete pavement. Grass-grass pavements are used for roads where firefighting vehicles enter only in fire emergency situations. For the same reason, it is recommended to use concrete pavement for the access road of the parking lot, while the parking space adopts grass grid to green parking space. Grass-grass grid base treatment for sidewalks: 1. History is based on the original. 2. Pave the grass planting grid on the compacted soil surface. 3. Sprinkle planting soil in the recessed planting trough of the grass-planting grid and sweep it evenly into the grass-planting grid holes with a broom. The height of the soil layer should be 5-10mm below the level of the grass-planting grid. 4. Spread sod on the grass grid. When laying turf, compact the turf on the planting soil. Watering and curing can be used after the grass survives. Construction Notes 1. The crushed stone foundation shall be compacted, the maximum bearing pressure shall be taken into consideration for the degree of compaction, and the surface shall be smooth, with a drainage slope of 1%-2% preferably. Pebbles or gravel and sand must be filled in the seepage holes of the concrete foundation to prevent soil loss. 2. Manila grass is generally used for turf, which is resistant to trampling and easy to grow. When laying the turf, leave a gap of about 20mm, and stagger the pavement in a pattern. After the turf is paved, irrigate it thoroughly with water to make the turf soft, and then use a small roller or flat vibration machine to press the grass roots into the planting grid (repeated many times) to make the grass roots easy to grow down. 3. Each planting grid has links to buckle, interlocking when paving. After the grass-planting grid is paved, use a small road roller or a flat vibrator to press the grass-planting grid back and forth once. Any unevenness needs to be trimmed until the grass-planting grid surface is level. 4. It is recommended to use high-quality nutrient soil for the filling soil in the planting grid. When returning to the soil, sprinkle water to allow the soil to settle down. Use a bamboo broom to evenly sweep the nutrient soil on the surface of the grass grid into the holes of the grass grid. The height of the soil layer should be 5-10mm lower than the grass grid plane. 5. The lawn needs to be trimmed 4-6 times a year, weeds are pulled out in time, and fertilizer is applied. In the hot and dry season, it should be frequently watered or equipped with automatic sprinkler equipment, and the necessary maintenance and management work should be done. 6. After one month of maintenance, stop for use; if it is between November and March of the following year (dormant period), it should be maintained for two months before parking. 7. During use or after the rainy season, if a small amount of planting soil is lost, you can evenly sprinkle some soil or sand from the lawn surface to fill the soil lost due to rain washing. 7. The lawn needs to be trimmed 4-6 times a year, weeds are pulled out in time, and fertilizer is applied. In the hot and dry season, it should be frequently watered or equipped with automatic sprinkler equipment, and the necessary maintenance and management work should be done.Waterproof Material website:http://www.geotechnicalmaterial.com/waterproof-material/
