Kangshang Construction Engineering Co., Ltd. is a specialized contractor for soft ground treatment, including dynamic compaction and dynamic compaction replacement. The company owns over 30 sets of new hydraulic dynamic 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. The company's management and technical team are among the earliest pioneers in the field, having gained high recognition and a good reputation through years of exploration and practice. We have earned positive feedback and recognition from a wide range of clients, gradually evolving into a brand company with strong equipment, technology, 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 and cost savings, and environmental friendliness.
(1) Application Scope: Compaction method can be used to reinforce various sandy soils, silty soils, general clayey soils, loess, artificial fill, especially suitable for reinforcing large aggregate 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 used for reinforcing soft soil foundations.
(2) Significant Reinforcement Effect: After the foundation is treated with dynamic compaction, it can significantly enhance 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 machines can be used with龙门架(kimono frame) 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 building materials, significantly reducing the consumption of construction materials.
(5) Cost-Effective: The dynamic compaction method is low-cost among commonly used foundation treatment techniques, being only 1/6 of CFG piles, 1/10 of mixing piles, and 1/2 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 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 the buildings, structures, and environment surrounding the construction site.
The dynamic compaction method is suitable for treating foundation soils such as crushed stone, sandy soil, low-saturation silt loam and clay, collapsible loess, unconsolidated fill, and mixed fill. After treatment, the foundation soil's strength is enhanced, its compressibility reduced, and its resistance to vibration-induced liquefaction improved. Therefore, dynamic compaction is also commonly used for treating地基 foundations prone to liquefaction, such as those made of liquefiable sand.
The dynamic compaction method is simple to operate, widely applicable to soil types, and significantly effective in reinforcement, capable of achieving higher bearing capacity, typically increasing the foundation strength by 2 to 5 times; it reduces deformation settlement and compressibility by 2 to 10 times; soil particles are tightly bonded, offering high structural strength; it is highly efficient with fast construction speed, cutting the construction period by 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.
