Kangshang Construction Engineering Co., Ltd. is a specialized contractor for soft foundation treatment, including dynamic compaction and dynamic replacement. The company owns over 30 sets of new hydraulic dynamic compaction equipment, capable of handling projects ranging from 1000kn.m to 20,000kn.m. Our services are nationwide, with over a thousand successful construction cases. The company's management and technical team are among the earliest builders in the field, gaining high recognition and a good reputation through years of exploration and practice. We have received positive feedback and recognition from numerous clients, gradually evolving into a professional foundation construction brand with strong equipment, technical, and management capabilities!

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

(1) Scope: Compaction method can be used to reinforce various types of sand, silt, clay, loess, and artificial fill soil. It is particularly suitable for reinforcing large-sized gravelly soils that are difficult to reinforce by general methods, as well as for reinforcing mixed fill soil composed of shallow, domestic, or industrial waste materials. The replacement method can also be used for reinforcing 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 is simple: The main equipment for dynamic compaction is crawler cranes. Substitute dynamic compaction equipment can be used with龙门架 (lattice girder) and other facilities when necessary to enhance lifting capacity and stability.

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

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

(6) Eco-Friendly: The stone column method of construction does not consume high-energy-consuming materials such as steel and cement, nor does it pollute the surrounding environment.

The main drawback of the dynamic compaction method is that it generates significant vibration and noise during construction, which can affect the surrounding buildings, structures, and environment.

The dynamic compaction method is suitable for treating foundations such as gravelly 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, dynamic compaction is often used for treating foundations with liquefiable sandy soil as well.

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 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 in 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.
