We have received positive feedback and recognition from a wide range of clients, gradually evolving into a brand company with strong equipment, technical, and management capabilities in foundation construction!
The main advantages of the dynamic compaction method include: wide application range, significant reinforcement effect, large effective reinforcement depth, simple construction equipment, material savings, cost savings, and environmental friendliness.
(1) Application Scope: Compaction method can be used to reinforce various sandy soils, silt soils, general clay soils, loess, artificial fills, especially suitable for reinforcing large-sized gravelly soils that are difficult to reinforce by general methods, as well as mixed fills composed of shallow, domestic waste, or industrial waste. The replacement method can also be employed to reinforce soft soil foundations.
(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 simple: 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, which can significantly reduce the consumption of construction materials.
(5) Cost-Effective: The dynamic compaction method is economically advantageous compared to commonly used foundation treatment processes, with a cost that is only 1/6 of CFG piles, 1/10 of mixing piles, and 1/2 of lime-soil piles.
(6) Eco-friendly: The compaction method used in construction does not consume materials like steel and cement, which are high-energy consumers, and it also does not pollute the surrounding environment.
The main drawback of the dynamic compaction method is that it generates significant vibration and noise during construction, which can impact surrounding buildings, structures, and the environment.
The dynamic compaction method is suitable for treating foundations such as crushed soil, sandy soil, low-saturation silt and clay, collapsible loess, unconsolidated 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, the dynamic compaction method is often used for treating foundations of liquefiable sandy soil, etc.
The compacting method is simple to operate, has a wide range of soil applicability, and demonstrates significant reinforcement effects, allowing for higher bearing capacity. The general foundation strength can be increased by 2 to 5 times; the deformation settlement is minimal, with compressibility reduced by 2 to 10 times; soil particles are tightly bound, providing high structural strength; high efficiency with rapid construction speed, cutting the construction period in half compared to soil replacement and backfilling; saves reinforcement materials; 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.
