Kangshang Construction Engineering Co., Ltd. is a professional contractor specializing in soil compaction and replacement, with over 30 sets of new hydraulic compaction equipment. We are capable of undertaking projects ranging from 1000kn.m to 20,000kn.m in soil compaction and replacement. Our services are nationwide, with over a thousand successful construction cases. Our management and technical team are among the earliest builders in the field, and after years of exploration and practice, we have gained high recognition and a good reputation in the industry. Praised and recognized by a large number of customers, we have gradually developed into a professional foundation construction brand with strong equipment, technical, and management capabilities!

The main advantages of the dynamic compaction method include: wide application range, significant reinforcement effect, 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 soils, general clay soils, loess, artificial fill soils, particularly suitable for reinforcing large-sized gravelly soils that are difficult to reinforce by general methods, as well as miscellaneous 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 being treated with dynamic compaction, the foundation soil's shear strength and bearing capacity are significantly improved, and its compressibility is reduced.

(3) Construction equipment is simple: The main equipment for dynamic compaction is crawler cranes. Substitute dynamic compaction equipment can be used with gantry structures or similar 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, 1/1 the cost of mixed piles, and 1/2 the cost of lime-soil piles.

(6) Eco-Friendly: The dynamic compaction method does not consume steel, cement, and other high-energy-consuming building materials, and it also 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 a certain impact on surrounding buildings, structures, and the 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 of liquefiable sandy soil, among others.

The dynamic compaction method is simple to operate, has a wide range of soil applicability, and demonstrates significant reinforcement effects, enabling higher bearing capacity, typically increasing the foundation 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 a fast construction speed, cutting the construction period by half compared to soil replacement and backfilling; it saves reinforcement materials; has low construction costs, reduces investment, saving 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.
