Kangshang Construction Engineering Co., Ltd. is a professional contractor specializing in deep compaction and deep compaction replacement for soft foundation treatment. The company owns over 30 sets of new hydraulic deep compaction equipment, capable of undertaking projects ranging from 1000 kn.m to 20,000 kn.m. Our services are nationwide, with over a thousand successful construction projects. Our management and technical team are among the earliest builders in the field, having gained significant recognition and a good reputation through years of exploration and practice. We have received praise and recognition from numerous clients, gradually establishing ourselves as 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 Scope: Compaction method can be used to reinforce various sandy soils, silt loams, general clayey soils, loess, artificial fill, particularly 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 used for reinforcing soft soil foundations.

(2) Significant Reinforcement Effect: After the foundation is treated with dynamic compaction, it can notably enhance 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 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 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 the cost of mixed piles, and 1/2 the cost of lime-soil piles.

(6) Eco-Friendly: The dynamic compaction method does not consume materials like steel and cement, which are high-energy consumers, and it 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 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, 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 as well.

The compaction method is simple to operate, suitable for a wide range of soil types, and has significant reinforcement effects, allowing for higher bearing capacity, typically increasing the ground strength by 2 to 5 times; it also reduces deformation and settlement by 2 to 10 times, with tightly bound soil particles and high structural strength; it is highly efficient, with fast 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 the cost compared to soil replacement and backfilling, and 50% to 70% of the investment compared to precast pile reinforcement, and 40% to 50% compared to sand piles.
