We are constructing sponge cities, integrating the functions of natural ecosystems with artificial interventions to effectively control stormwater runoff. This approach achieves urban development through natural storage, infiltration, and purification, benefiting the restoration of urban water ecosystems, conservation of water resources, enhancement of flood control capabilities, expansion of effective public product investments, and improvement of the quality of new urbanization. It promotes a harmonious development between humans and nature.

Garage Roof Siphon Drainage System

By utilizing the siphon principle, the system has transitioned from passive to active drainage, effectively resolving the issue of clogged drainage. This innovation can reduce costs and construction timelines, extend the building's lifespan, and allow for the reuse of collected water.

Roof Garden Greening and Drainage System

The roof greening and water retention and drainage system boasts dual comprehensive functions of water retention and drainage. The boards feature spatial rigidity, with明显的compression resistance superior to similar products (which can be verified through on-site tests). It is capable of withstanding compressive loads over 400KPA and can endure extreme load conditions caused by mechanical compaction during the backfilling process for the planting roof deck.

Section 3: Rainwater Collection and Utilization System

The rainwater collection and utilization system collects rainwater through pipes, intercepts and collects runoff pollutants, stores rainwater in a PP rainwater collection pond, filters and disinfects it, and achieves automatic discharge of pollutants, purification, and collection. It embodies the features of true energy saving, environmental protection, long service life, and low cost.

Four: Waterproof and Drainage System for Basement Slab

The voids formed by the concrete supports cast in the grooves of the drainage boards effectively protect the waterproofing quality, ensuring groundwater seepage is排出, and achieve the functions of preventing seepage and moisture, reducing long-term maintenance costs.

Section 5: Brief Introduction to Siphon Drainage System Construction

The collection method involves infiltrating soil into water that continuously flows through long-lasting composite drainage boards into siphon drainage channels. The water in the siphon drainage channels quickly accumulates at the outlet, which then changes in pipe diameter to form a full flow in the siphon straight pipe, initiating the siphon action. The water then sequentially enters observation wells and collection wells for reuse. The construction process involves sequentially laying adhesive strips, siphon drainage channels, long-lasting composite drainage boards, reducer pipes, observation wells, and collection wells. The siphon drainage collection method and construction process eliminate the need for slope grading and waterproofing treatments. By utilizing the principle of siphon, it changes the passive drainage to active drainage, effectively solving issues such as incomplete drainage, leaks, and vegetation damage in existing drainage structures. This approach can reduce costs and construction time, extend the service life of buildings, and allow for the reuse of collected water.

VI. Features of Long-lasting Composite Drainage Sheets:

(1) Features include drainage, water retention, insulation, moisture and water-resistant layer flexibility protection.

High compressive strength, stable chemical properties, acid and alkali resistance, and shock resistance.

The varying gap sizes between the bosses determine different drainage capabilities and air layer thicknesses, catering to the needs of various engineering projects.

(4) Construction Safety and Convenience: The advanced production process of long-lasting composite drainage boards ensures precise and uniform spacing between plastic bosses, allowing for connections between sheet materials through flat seam bonding, fulcrum lapping, or hot welding, guaranteeing the quality of the connections on the long-lasting composite drainage boards.

(5) Long-lasting lifespan.

Seven: Functional Features of Long-lasting Composite Drainage Plates

(1) The long-lasting composite drainage board for roofing waterproofing primarily serves drainage purposes. In a green roof system that combines waterproofing and drainage, the long-lasting composite drainage board effectively handles both drainage and water retention.

(2) Subsurface Drainage: Utilizing long-lasting composite drainage boards to expel seepage water around the foundation, preventing erosion of the base plate; on the exterior wall of the underground room facing the water, the use of long-lasting composite drainage allows for the expulsion of groundwater, thus avoiding erosion to the exterior wall of the underground room.

(3) Municipal Road Drainage: Timely draining of infiltrated water, which prevents capillary phenomena in the road subgrade; in newly constructed roads, a long-lasting composite drainage board is placed on the subgrade base, effectively reducing subgrade materials, simplifying construction, shortening project duration, and preventing issues like rutting and cracking of blacktop surfaces.
