How to construct greening: hot topics and structured guide on the Internet in the past 10 days
With the acceleration of urbanization, greening construction has become a hot topic on the Internet recently. This article will provide you with a structured data guide from the construction process, technical points, cost control and other dimensions based on the hot spots across the Internet in the past 10 days.
1. Top 5 hot topics in recent greening construction
Ranking | Topic keywords | Search volume (10,000) | Main discussion points |
---|---|---|---|
1 | Sponge city greening | 142.6 | Rainwater infiltration system construction |
2 | vertical green wall | 98.3 | Modular installation technology |
3 | roof garden | 87.5 | Waterproof layer treatment specifications |
4 | low cost greening | 76.2 | Native plant applications |
5 | Smart irrigation | 65.8 | Internet of things control system |
2. Decomposition of standardized construction process
stage | Work content | technical standards | Construction period proportion |
---|---|---|---|
Preliminary preparation | Soil testing, laying out positioning | GB/T 50326-2022 | 15% |
Earthworks | Terrain shaping, drainage system | CJJ/T 82-2012 | 25% |
plant cultivation | Tree support and dense shrub planting | DB11/T 212-2023 | 35% |
Maintenance management | Watering, pruning and replanting | LY/T 2584-2023 | 25% |
3. Detailed explanation of hotspot construction technologies
1.Key technologies of sponge city:Pay attention to the recently popular permeable pavement construction: ① Use graded gravel thickness as the base layer ≥ 30cm ② Permeable concrete strength C20-C25 ③ Reserve 5-8mm expansion joints for joint treatment.
2.Controversial points about vertical greening:The anti-root puncture solution that netizens are most concerned about is recommended to use: HDPE anti-root membrane (thickness ≥ 1.2mm) + stainless steel support frame (304 material), which can guarantee a service life of more than 10 years.
3.Smart irrigation configuration:According to recent bidding data, the mainstream configuration includes: ① soil moisture sensor ② weather station linkage ③ solenoid valve controller ④ mobile APP remote control. The cost of the entire system is about 120-180 yuan/㎡.
4. Key data for cost control
Project type | Unit price (yuan/㎡) | Material proportion | Manual proportion |
---|---|---|---|
Ordinary green space | 80-120 | 45% | 55% |
roof garden | 350-600 | 60% | 40% |
vertical greening | 800-1500 | 70% | 30% |
5. Construction precautions
1.Season selection:The planting time should be selected according to the characteristics of the plant. Deciduous trees should be planted before budding in spring or after falling leaves in autumn.
2.Soil improvement:In response to the recently exposed soil pollution problem, the pH value needs to be tested (appropriate range 6.0-7.5), and humus soil (proportion ≥ 30%) needs to be added if necessary.
3.Acceptance criteria:Focus on key indicators such as survival rate (trees ≥95%, shrubs ≥98%), flatness error (≤5cm/10m).
Through the above structured data, the technical key points and market trends of current greening construction can be systematically grasped. It is recommended that the construction party give priority to new technologies and new materials that have been hotly discussed recently based on the specific conditions of the project, while paying attention to cost control and quality balance.
