We have received positive feedback and recognition from a wide range of clients, gradually developing into a brand company with strong equipment, technical, and management capabilities in foundation construction!

The main advantages of the dynamic compaction method include: wide applicability, significant reinforcement effects, large effective reinforcement depth, simple construction equipment, material and cost savings, and environmental friendliness.

(1) Application Range: Compaction method can be used for reinforcement of various sand, silt, general clay, loess, and artificial fill soils. It is particularly suitable for reinforcing large aggregates of soil types that are difficult to reinforce by general methods, as well as for mixed fill soils composed of shallow, domestic waste, or industrial waste. The displacement method can also be employed for soft soil foundation reinforcement.

(2) Enhanced Reinforcement Effect: After the foundation is treated with dynamic compaction, it can significantly improve the shear strength and bearing capacity of the soil, and reduce its compressibility.

(3) Construction Equipment Simplicity: The main equipment for dynamic compaction is crawler cranes. Substitute dynamic compaction equipment can be used with gantry frames and other facilities when necessary to enhance lifting capacity and stability.

(4) Material Savings: Compared to other foundation treatment methods, the dynamic compaction method does not require steel, cement, and other construction materials, significantly reducing the consumption of construction materials.

(5) Cost Savings: The dynamic compaction method is cost-effective compared to commonly used ground treatment techniques, being only 1/6 the cost of CFG piles, 1/10 of mixed piles, and 1/2 of lime-soil piles.

(6) Eco-Friendly: The dynamic compaction method does not consume high-energy-consuming building materials like steel and cement, nor does it pollute the surrounding environment.

The main drawback of the dynamic compaction method is that it generates significant vibrations and noise during construction, which can impact the surrounding buildings and environment of the work site.

The dynamic compaction method is suitable for treating foundations made of gravelly soil, sandy soil, low-saturation silt and clay, collapsible loess, clean fill, and mixed fill. After treatment, the foundation soil's strength is enhanced and its compressibility reduced, while also improving its resistance to vibration-induced liquefaction. Therefore, dynamic compaction is often used to treat liquefiable sand soil foundations, etc.

The dynamic compaction method is simple to operate, widely applicable to soil types, and significantly enhances reinforcement, achieving higher bearing capacity, typically increasing the ground strength by 2 to 5 times; it reduces deformation settlement by 2 to 10 times; soil particles are tightly bound, offering high structural strength; it is highly efficient with rapid construction speed, cutting the construction period by half compared to soil replacement and backfilling; it saves reinforcement materials; has low construction costs, reducing investment; it saves 60% of costs compared to soil replacement and backfilling, and 50% to 70% of investment compared to precast pile reinforcement, and 40% to 50% compared to sand piles.
