We have earned the praise and recognition of our clients, and are gradually establishing ourselves as a strong brand company in the field of foundation construction, boasting robust equipment, technical strength, and management capabilities!

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) Scope: Compaction method can be used for reinforcing various sandy soils, silty soils, general clayey soils, loess, artificial fill, especially suitable for reinforcing large gravelly soils that are difficult to reinforce by general methods, as well as for mixed fills composed of shallow, domestic waste, or industrial waste. The replacement method can also be used for reinforcing soft soil foundations.

(2) Enhanced Reinforcement Effect: After undergoing strong compaction treatment, the foundation soil's shear strength and bearing capacity are significantly improved, and its compressibility is reduced.

(3) Construction Equipment Simplicity: The main equipment for dynamic compaction is crawler cranes. As an alternative, gantry frames and similar facilities can be used for dynamic compaction as needed 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 technologies, being only 1/6th the cost of CFG piles, 1/10th of mixed piles, and 1/2 of lime-soil piles.

(6) Eco-Friendly: The compaction method used in construction does not consume materials such as steel and cement, which are high-energy consumers, and does not pollute the surrounding environment.

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

The dynamic compaction method is suitable for treating foundations such as gravelly soil, sandy soil, low-saturation silt and clay, collapsible loess, plain fill, and mixed fill. The treated foundation not only enhances the strength of the soil but also reduces its compressibility, while also improving its resistance to vibration-induced liquefaction. Therefore, dynamic compaction is often used for treating foundations with liquefiable sandy soil, among others.

The dynamic compaction method is simple to operate, suitable for a wide range of soil types, and produces significant reinforcement effects. It can achieve higher bearing capacity, typically increasing the ground strength by 2 to 5 times; it reduces deformation settlement and compressibility by 2 to 10 times; the soil particles are tightly bound, offering high structural strength; it is highly efficient, with rapid construction speed, cutting the construction period in half compared to soil replacement and backfilling; it saves reinforcement materials; has low construction costs, reduces investment; 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.
