The Pasay Reclamation Development Project is located in Manila Bay, Philippines. This modern commercial and residential real estate development is spearheaded by SM Intelligent Urban Infrastructure and Development Company in collaboration with the Philippine Reclamation Authority (PRA) and Pasay City. The planned project area covers approximately 396 hectares, involving the reclamation of four artificial islands: A, B, C, and D.
Our company is responsible for geological exploration, foundation treatment construction, and testing of islands A and C. The geological exploration utilized the cone static penetration test (CPT), while the foundation treatment process involved vibration compaction and surface compaction. Testing was conducted using on-site sampling and advanced testing methods.
The project’s design scope included approximately 44 million cubic meters for vibration compaction and an additional 3.17 million cubic meters for surface compaction. The project was completed and opened in May 2023.
The Lok Ma Chau Hetao area in Hong Kong is located at the junction of Hong Kong and Shenzhen, covering approximately 87.7 hectares. It is formed by the intersection of the new and old Shenzhen waterways on the eastern side of Huanggang Lok Ma Chau Port. In 2017, the governments of Hong Kong and Shenzhen signed a memorandum of cooperation to jointly develop the “Hong Kong-Shenzhen Innovation and Technology Park” in the Lok Ma Chau Hetao area. This collaboration aims to establish key scientific research hubs within the park, ensuring long-term economic development for both cities.
The foundation treatment plan for land remediation and preliminary engineering in the Luomazhou Hetao area employs onshore dry-method bottom discharge gravel pile construction technology. This method is characterized by its efficiency in drilling, densification, and transportation of stone material using high-pressure gas in a closed system.
Compared to traditional vibrating and punching gravel pile methods, the dry-method process offers several advantages:
1. It requires minimal circulating cooling water, conserving a significant amount of resources.
2. It avoids mud discharge during construction, preventing environmental pollution and enhancing eco-friendliness.
3. It ensures direct placement of stone material at the pile bottom, resulting in higher pile quality and better permeability.
The project features 1.0m × 1.7m rectangular laid piles, with the longest pile reaching a construction depth of 18.5 meters. During execution, six pile drivers and six sets of dry bottom discharge vibration and compaction equipment were deployed. Approximately 10,000 gravel piles were completed, totaling around 140,000 meters in construction.
The proposed Vila Port Shopping Center is located in the city center of Vila Port, the capital of Vanuatu. Upon completion, it will become the largest shopping venue in Vila Port. The geological conditions at the site are complex, with significant variations in the thickness of the covering soil layer. The soil primarily consists of coral sand, with large stones distributed in the upper layer, some exceeding 200 millimeters in size. Additionally, clay interlayers are present at the bottom of the coral sand.
Our company is responsible for the design and construction of the foundation treatment for this project, covering an area of approximately 4,000 square meters, with pile lengths ranging from 10 to 30 meters.
During construction, the low density and strength of the coral sand particles were carefully considered. Measures were implemented to reduce water pressure and volume during operations. In some areas, high-pressure gas was used, transported via air compressors, to replace construction water and minimize disturbance to the soil layer while reducing mud slurry discharge.
This project successfully completed a total of 21,000 meters of vibroflotation work.
The Fujairah Strategic Grain Reserve Project is located in Fujairah Port, UAE, and constitutes a critical development in grain storage infrastructure. The first phase of the project includes 20 silos, auxiliary work towers, packaging towers, and drying towers. The project aims to achieve a composite foundation with a bearing capacity of 350 kPa. It strictly controls total settlement, uneven settlement, and settlement differences between adjacent buildings to within 50 millimeters. Additionally, the maximum allowable inclination rate of the foundation is limited to 0.2%.
Our company undertook the design, construction, and testing of the foundation improvement for this project. The ground improvement process utilized vibro-stone column technology with a treatment range of 6.0 meters beyond the structure’s outer edge. The design specifications included columns with a diameter of 1,100 millimeters and lengths ranging from 12 to 17 meters.
During construction, the company deployed its independently developed BJ-150 and CV350 vibroflotation machines. These machines efficiently completed approximately 100,000 linear meters of vibro-stone column installation, ensuring the foundation met the project’s stringent requirements for load-bearing capacity and stability.
This project represents a significant advancement in ground improvement techniques for large-scale storage facilities, particularly in petroleum, chemical, and grain industries, contributing to the UAE’s strategic infrastructure development.
