Integrate urban water environment management with the advancement of sponge city construction. Incorporate sponge elements into projects such as the remediation of black and smelly water bodies, water system park construction, and riverway management. Utilize下沉式绿地, grassed swales, rainwater wetlands, permeable paving, ecological revetments, and multi-functional storage measures, adhering to principles like ecological precedence, to perform the functions of water absorption, storage, infiltration, and purification during rainfall.
The primary advantages of permeable paving:
1. Paved surfaces drain effectively post-rain, preventing urban flooding, enhancing pedestrian safety, and keeping clothing clean.
2. Permeable paving collects water resources, aiding in groundwater conservation and addressing the issue of decreasing groundwater levels caused by recent travel patterns.
3. Hot weather can evaporate moisture, increase humidity in the air, and alleviate the heat island effect.
4. Reducing the amount of urban paving can alleviate dust pollution and decrease the frequency of water trucks during summer.
5. A wide range of color options, allowing for intricate pattern designs, catering to personalized preferences, enhancing environmental aesthetics, and infusing artistic flair.
6. Easy to install, more cost-effective than permeable bricks and asphalt, and also reduces the costs for later greening maintenance and road maintenance.
7. The strength requirement can reach C30, capable of handling most garden landscapes, community squares, and municipal roads.
Porous pavement features high porosity in all layers, allowing rainfall to infiltrate through the entire surface. It adheres to the application regulations for hardened ground surfaces while also benefiting from the ecological advantages of natural lawns and soil. This enhances soil permeability and aeration, significantly reducing runoff, replenishing groundwater, and showcasing a sustainable concept of coexistence with the ecosystem.
Honeycomb municipal road paving is most commonly seen in colored concrete surfaces. This is due to the ease and speed of colored concrete construction, its strength, load-bearing capacity, and long service life. With the construction and advancement of sponge cities, permeable concrete is increasingly demonstrating its status as the main force in urban construction.
The composition and mechanism of action of the materials are as follows: Permeable concrete material: water + cement + aggregate + permeable concrete reinforcing agent + surface protective agent. Participates in the cement hydration reaction to form a polymer cement hydration body; significantly enhances the compressive and adhesive strength of the cement hydration body; improves the concrete's frost-thaw resistance, durability, and weather resistance.
