In the process of urbanization, the greening projects of parking lots and fire lanes face two core pain points: First, the traditional green ground is difficult to withstand the frequent rolling of vehicles, resulting in turf damage and soil compaction; Second, fire lanes need to meet both the emergency passage requirements and the greening rate index, and ordinary lawns cannot balance the load strength and ecological functions. Jiamei New Materials Co., Ltd. has been deeply involved in the drainage system field for more than a decade. With a 32,000-square-meter production base and 25 production lines in Tai'an High-tech Development Zone, it has extended the siphon drainage technology to the grass planting grid system, innovatively solving the above contradictions.
The 7-cm grass planting grid we developed adopts a patented support structure (the patent number refers to the auxiliary materials). Through the honeycomb-shaped three-dimensional design, it disperses the vehicle load. Its core advantages are as follows:
- Triple mechanical protection: The compressive strength of the top bearing layer is ≥25 tons/㎡. The middle drainage groove realizes rapid drainage with zero slope, and the bottom anti-settlement base reduces soil displacement.
- Ecological synergy: The air permeability rate of over 60% ensures the normal growth of grass roots. When used in combination with the HXC siphon drainage groove, it can increase the rainwater utilization rate by 30%.
- Modular installation: The snap-on connection system saves 50% of the construction time and supports cutting in irregular areas.
| Parameter category | Technical indicators | Test standards |
|---|---|---|
| Single grid size | 400×400×70mm (customizable) | GB/T 1040 |
| Water permeability rate | ≥650L/m²·min | JTGE 20-2011 |
| Compressive strength | Fire lane level: ≥25MPa | GB/T 1041 |
| Operating temperature | -35℃~75℃ | GB/T 1037 |
| Material composition | Modified PP + 30% glass fiber reinforcement | ISO 527 |
Actual engineering verification shows that the grass planting grid system can maintain a 15 - year maintenance - free cycle in the application of fire lanes, which is guaranteed by three key technologies:
- Load dispersion technology: The hexagonal support columns convert point loads into surface loads, reducing the pressure on the base layer.
- Drainage and anti - silt design: The 45° inclined drainage grooves prevent the deposition of debris and are used in conjunction with PED polymer drainage boards.
- UV - resistant treatment: Adding 2.5% carbon black masterbatch, the strength retention rate after 5000 hours of UV irradiation is > 92%.
Based on the production guarantee system with an annual production capacity of 50 million square meters, we support full - specification customization services. We can provide targeted solutions from light - duty parking lots (15 - ton class) to heavy - duty fire lanes (30 - ton class). Jiamei New Materials Co., Ltd. holds the second - level construction qualification for waterproofing, anti - corrosion and thermal insulation and 22 utility model patents, and has passed the AAA - level enterprise credit certification. The project delivery is equipped with full - process technical support. It is recommended that engineering parties select the corresponding models according to the bearing capacity of the foundation: the standard model is recommended for sandy foundations, and silt - like soil layers need to be used in conjunction with siphon drainage grooves. If you need to obtain load calculation tools or construction simulation plans, please feel free to contact the technical team for scenario - based configuration consultation.
FAQ:
Q: Can the grass planting grid be directly laid on the concrete base layer?
A: It is not recommended to lay it directly. A 5cm graded gravel leveling layer (particle size 10 - 20mm) should be laid on the concrete base layer first, then covered with a geotextile filter layer, and finally the grass planting grid should be installed. This structure can avoid the frost heave damage of the base layer caused by water accumulation and improve the durability of the system.
Q: What is the fire - resistant performance of the grass planting grid for fire lanes?
A: The product has passed the GB8624 B1 - level flame - retardant test. The added flame retardant can form a carbonized protective layer at a high temperature of 650℃ to delay the spread of the flame. However, in actual use, the dry grass in the grid still needs to be cleaned regularly. It is recommended to check the vegetation status every quarter.
Q: How much is the bearing capacity difference between the 70mm - thick and 50mm - thick products?
A: Increasing the thickness by 20mm can increase the flexural stiffness by about 1.8 times. In the wheel - pressure test of the fire truck lane, the deformation of the 70mm product is controlled within 3.2mm (5.8mm for the 50mm product), which is more suitable for the passage of emergency rescue vehicles.
Q: How to solve the soil compaction in the grass planting grid?
A: It is recommended to use a mixed filler of 80% coarse sand + 20% organic matter, and the porosity needs to be >35%. In spring and autumn every year, cooperate with the punching and aeration operation. It is better to penetrate the bottom of the grid. The permeability rate can be maintained above 85% of the design value.
Q: How to prevent frost heaving damage in extremely cold regions?
A: In an environment below -20℃, an anti - freezing structure of double - layer geotextile sandwiching a drainage board should be adopted: base layer → drainage board → geotextile → 150mm gravel layer → geotextile → grass planting grid. This structure can control the freezing depth within 100mm.
Q: What is the composition of the comprehensive cost per square meter of the grass planting grid system?
A: It mainly includes three parts: the material cost is about 45 - 60 yuan (including auxiliary materials), the base layer treatment cost is 15 - 25 yuan, and the planting and maintenance cost is 20 - 30 yuan. Compared with the traditional hardened ground, the maintenance cost can be reduced by 37% within 8 years.
