Our Solution

Water Conservancy & Aquaculture Solutions

1.Industry Pain Points & Challenges In canal water conveyance and aquaculture, water loss and environmental control are the biggest challenges: (1) Severe seepage loss: Traditional earthen canals or damaged concrete canals have a water seepage rate as high as 40%-60%, resulting in a huge waste of water resources. (2) Difficulty in water quality control: Earthen pond aquaculture is susceptible to contamination by soil bacteria and parasites, making pond cleaning difficult, and bottom sediment easily leads to a decrease in dissolved oxygen, affecting the survival rate of fish and shrimp. (3) Structural instability and collapse: River channels or fishpond slopes are prone to collapse under the scouring of water flow, resulting in high maintenance costs. 2.Our System Solution Changfeng’s “seepage prevention + stabilization + hygiene” solution: (1) High-efficiency canal seepage prevention: Using composite geomembrane. This product is a composite of geotextile and geomembrane, providing both seepage prevention and strong puncture resistance through the geotextile surface. (2) Ecological Aquaculture Barrier: Smooth HDPE Liner is used to lay the pond bottom. It not only completely isolates the pond from soil pollution but also has a smooth surface, allowing for rapid pond cleaning and significantly shortening the aquaculture cycle. (3) Embankment Stabilization System: Geobags or gabions are used to fill the embankment with stones or soil, forming a flexible slope protection structure to resist water erosion. 3.Core Advantages (1) Reduces Water Loss by 90%: The composite seepage prevention system minimizes water loss and doubles water resource utilization. (2) Reduces Pond Cleaning Time by 70%: The HDPE membrane surface does not accumulate mud, facilitating aquaculture wastewater discharge and reducing pond cleaning time from several weeks to several days. (3) 20% Reduction in Overall Construction Costs: Compared to full concrete lining, the geotextile material solution offers 3 times faster construction speed and virtually zero post-construction maintenance. 4.Case Studies & Related Products Typical Case: Seepage prevention project for a large-scale white shrimp farm in Southeast Asia, achieving a 30% increase in annual production.

Slope Protection and Ecological Restoration Solution

1.Industry Pain Points & Challenges In highway slope, mountain restoration, and riverbank protection projects, the most challenging issues include: (1) Severe soil erosion: Rainwater erosion leads to gully formation on slopes, even triggering landslide risks. (2) Difficulty in plant growth: Steep or rocky slopes cannot retain water and nutrients, making it difficult for vegetation to survive, resulting in a “white mountain stubble” phenomenon. (3) High cost and unsightly nature of traditional reinforced concrete: Concrete spraying and anchoring are extremely expensive and damage the natural landscape, failing to meet modern ecological and environmental protection requirements. 2.Our System Solution Changfeng’s “Three-Dimensional Soil Stabilization + Vegetation Greening” solution includes: (1) Slope honeycomb constraint system: Using geocells. These are unfolded on the slope and filled with soil, rock, or vegetation soil, with the honeycomb-like three-dimensional structure firmly locking the filler. (2) Surface erosion control: Laying coconut fiber mats or geomats slows runoff velocity through their fiber structure, protecting seeds from being washed away. (3) Ecological bank protection: Using gabions combined with geotextiles satisfies both structural strength requirements and allows for water and air exchange. 3.Core Advantages (1) Supports greening of steep slopes (45°+): The mechanical anchoring force of geocells makes greening of steep slopes possible, effectively preventing overall landslides. (2) Surface runoff reduction of 80%: The erosion control mat absorbs the impact of rainwater, significantly reducing the initial runoff’s cutting effect on the slope. (3) Rapid revegetation in 4-8 weeks: Providing a stable micro-ecological space for plant roots, achieving greening within the same year of construction. 4.Case Studies & Related Products Typical case: The slope protection project of the Abidjan Highway extension in Côte d’Ivoire successfully achieved the dual goals of “engineering safety and ecological landscape”.

Mining & Industrial Energy Solutions

1.Industry Pain Points & Challenges In gold mining (especially placer gold mining and sluice box beneficiation), mine owners often face the following losses: (1) Significant loss of fine-grained gold: Traditional sluice boxes or inferior bedding materials cannot effectively intercept tiny fine-grained gold particles, resulting in significant loss along with the tailings and direct profit losses. (2) Rapid wear and tear on gravity separation equipment: Ore sand has extremely strong abrasive properties; ordinary carpets or mats are easily worn down by sludge and require frequent shutdowns for replacement. (3) Difficulty in cleaning and recycling: Some gold-catching mats have unreasonable structural designs, making it difficult to thoroughly clean the gold powder adhering to them, resulting in secondary waste. -Damage to heavily loaded road surfaces in mining areas: Ore trucks cause unstable roadbeds, affecting the overall production rhythm. 2.System Solution Changfeng offers a professional combination of “High-Efficiency Gold Extraction + Mine Area Reinforcement”: (1) High-Efficiency Sluice Box Gold Extraction System: Utilizes professional gold-finding carpet. Its unique fiber structure forms micro-vortices, using gravity differences to firmly lock in heavy metal particles (such as gold), effectively preventing fine gold from escaping. (2) Heavy-Duty Road Reinforcement in the Mine Area: Uses high-strength geogrids to enhance the shear strength of the ore transport roadbed, ensuring unimpeded passage for heavy engineering machinery. (3) Heap Leaching Site Safety and Seepage Prevention: Lays a high-thickness HDPE geomembrane in the heap leaching area to ensure 100% collection of precious solutions containing cyanide. (4) Foundation Layer Stabilization and Constraint: Utilizes geocells to provide three-dimensional constraint on the soft foundation of the mine area, improving the overall modulus of the foundation. 3.

(4) All-Terrain Adaptability: Whether used in large gold dredges, sluices, or river hand sorting, it exhibits excellent gravity capture performance. 4.Case Studies & Related Products Typical Cases: Multiple large-scale gold mine projects in Africa, South America, and Central Asia.

Urban Landscaping & Sponge City Solutions

1.Industry Pain Points & Challenges Common “urban diseases” in modern urban development: (1) Heat island effect and waterlogging: Excessive hard paving in cities prevents rainwater from infiltrating, resulting in severe urban flooding. (2) Parking vs. green space conflict: In limited spaces, parking spaces and green areas are often mutually exclusive. (3) Rooftop garden leakage: If rooftop greening has poor drainage, water accumulation will put pressure on the building structure and cause indoor water leakage. 2.Our System Solution Changfeng’s “permeable + water storage and drainage” solution in response to the “sponge city” policy: (1) Green ecological parking spaces: Using high-strength grass pavers instead of traditional concrete bricks allows the lawn to thrive even under vehicle traffic. (2) Roof Green Drainage System: A storage and drainage board is installed, which stores some water to supply plants while quickly draining excess rainwater. (3) Underground Space Drainage: A capillary drainage plate is used to guide groundwater out in an orderly manner, protecting the building’s foundation. 3.Core Advantages (1) 50% Increase in Green Space Ratio: Transforming a previously barren parking lot into a green oasis. (2) 100% Permeability: Rainwater infiltrates immediately on-site, effectively relieving pressure on the urban pipe network and eliminating water accumulation.

Railway & Tunnel Engineering Solutions

1.Industry Pain Points & Challenges Railway and tunnel engineering is a national-level high-standard infrastructure project, with extremely high requirements for material durability and dynamic stability: (1) High-frequency dynamic load challenge: High-speed and heavy-haul railways generate huge vibration loads during operation, causing the ballast (crushed stone layer) to wear against each other, break, and sink into the roadbed, leading to road surface settlement. (2) Tunnel water leakage problem: Groundwater pressure is huge. If the waterproof layer is not tight or drainage is not smooth, water will seep into the tunnel walls and form ice, seriously threatening the safety of train operation. (3) Freeze-thaw settlement problem: In cold regions, the roadbed cannot drain moisture in time, and repeated freeze-thaw cycles will cause railway track deformation and heave. -Unstable slope structure: Deep cut slopes along railway lines are easily weathered and eroded by rainwater, resulting in rockfalls or local collapses. 2.System Solution Changfeng’s “Structural Reinforcement + Tight Waterproofing + Rapid Drainage” Railway Solution: (1) Ballast and Subgrade Reinforcement: Steel-Plastic Geogrid is laid at the bottom of the ballast layer. Its extremely high tensile modulus locks in the displacement of gravel, reduces particle breakage, and maintains the stability of the track geometry. (2) Tunnel Waterproof Structure Layer: A specialized waterproof geomembrane is used as the main barrier for waterproofing the tunnel lining, preventing groundwater intrusion. (3) Permanent Drainage Network: Hard Permeable Pipes and Plastic Blind Ditches are buried in the tunnel side ditches and subgrade. Using capillary action, accumulated water is rapidly guided to the main drainage pipes. (4) Rapid Protection of Interception Ditches and Slopes: Cement blankets are used to lay interception ditches on both sides of the railway, achieving rapid hardening by “blanket to concrete,” preventing rainwater infiltration and erosion of the roadbed. 3.Core Advantages of the Solution (1) 300% Increase in Maintenance Cycle: Steel-plastic grating effectively reduces the ballast pulverization rate, significantly reducing the frequency of maintenance and cleaning of the railway track bed, saving huge maintenance costs. (2) Highly Efficient Drainage with “Zero Water Accumulation”: The combination of plastic blind drains and permeable pipes solves the problem of groundwater accumulation, effectively preventing frost heave disasters and ensuring all-weather operation of trains in cold regions. (3) Self-Healing Structure and Long-Term Waterproofing: The GCL waterproof blanket used in conjunction has a self-healing function upon contact with water, providing reliable waterproofing for tunnels for up to 100 years. (4) Breakthrough in Construction Efficiency: The application of new materials such as cement blankets eliminates the need for mixers and formwork when laying drainage ditches, making construction 5-10 times faster than traditional cast-in-place concrete. 4.Case Studies & Related Products Typical Case: Expansion Project of the Heavy-Haul Railway in Northern Kazakhstan.

Transportation Infrastructure Solutions

1.Industry Pain Points & Challenges In road and railway construction, contractors often face the following headaches: (1) Uneven subgrade settlement: Insufficient bearing capacity of soft soil foundations leads to cracking, collapse, or rutting of the road surface under vehicle loads. (2) High maintenance costs: Due to unstable foundations, frequent repairs are required after road delivery, severely depleting the subsequent operating budget. (3) Excessive gravel layer thickness: To achieve the design strength, traditional solutions require a huge amount of gravel and filler, leading to a surge in procurement and logistics costs. (4) Extreme weather effects: Freeze-thaw cycles cause displacement within the subgrade structure, damaging the road’s integrity. 2.System Solution Changfeng offers a multi-dimensional structural solution combining reinforcement, isolation, and drainage: (1) Subgrade Reinforcement Layer: Biaxial geogrid is used to lock the crushed stone fill, forming a stable “rigid cushion layer” that effectively disperses vertical loads. (2) Soft Soil Reinforcement System: For extremely soft foundations, geocells are used to provide lateral restraint and prevent lateral displacement of the fill material. (3) Filtration and Isolation Layer: Nonwoven geotextile is laid to prevent mixing of materials between layers and ensure unobstructed drainage. 3.Core Advantages (1) 40% Increase in Bearing Capacity: Actual measurements show that the bearing capacity of the reinforced subgrade is more than 40% higher than that of the unreinforced solution. (2) 30% Material Cost Savings: Due to the significant increase in structural strength from the reinforcement layer, the thickness of the crushed stone fill can be reduced by approximately 30%. (3) Extends service life by 2 times: Effectively inhibits reflective cracking, extending the road overhaul cycle by more than double and significantly reducing the total life cycle cost. 4.Case Studies & Related Products Typical case: Solving the subgrade settlement problem in the Kenya National Highway Subgrade Enhancement Project (50,000㎡).
