Dongying Port Foundation Reinforcement Project
The foundation reinforcement project within the oil storage area of the Dongying Port Project, undertaken by Dongying Port Co., Ltd., covers a total ground‑treatment area of approximately 1.0114 million square meters and employs the dual‑control dynamic consolidation method. Under operating conditions as low as −5°C, our company utilized electroosmotic wellpoint dewatering and plastic drainage‑board‑reinforced compaction, among other construction techniques, to ensure both schedule adherence and high‑quality results.
Chongqing Chemical & Pharmaceutical MDI Integrated Project
Section C of the site pre‑treatment (dynamic compaction) works for the Chongqing MDI Integrated Project is a development undertaken by Chongqing Chemical & Pharmaceutical Holdings (Group) Co., Ltd. in the Changshou Economic and Technological Development Zone, Chongqing. The total area of ground improvement amounts to approximately 404,100 square meters, with a contract duration of 90 days. The company has deployed 15 sets of dynamic compaction equipment, each delivering an energy level of 4,000–8,000 kN·m.
Zhenhai Refining & Chemical’s 1-million-ton-per-year ethylene project is the first in China to directly achieve an annual production capacity of one million tons. The project has received high-level attention from both the Zhejiang Provincial Party Committee and Sinopec headquarters; at the time, Xi Jinping, then Secretary of the Zhejiang Provincial Party Committee, personally presided over the groundbreaking ceremony. This milestone laid the foundation for Zhenhai Refining & Chemical to become the industry leader in both profitability and refining scale. Our company was primarily responsible for constructing the pile foundations for the ethylene cracking unit, the district utility tunnel, as well as the external process heating pipelines for propylene oxide, styrene, and the entire plant, completing a total of 90,000 cubic meters of piling work.
The Sinopec Tianjin Crude Oil Commercial Storage Facility, one of the largest storage complexes in North China, is an important crude oil storage project for Sinopec in the Beijing–Tianjin–Hebei region and represents the company’s single‑phase, largest‑scale domestic inventory‑construction initiative. The company has successfully completed the fabrication and installation of pile foundations for Sections 5, as well as portions of Sections 1 and 2, totaling 55,000 cubic meters of precast concrete square piles fabricated and installed on site, earning high praise from the Sinopec Pipeline Bureau.
The Sinopec Tianjin National Crude Oil Storage Facility, located in the Binhai Development Zone of Tianjin and adjacent to the Bohai Sea, is one of the largest crude oil storage projects in North China. Commissioned by the National Development and Reform Commission, it is a major national strategic oil reserve complex managed and constructed by Sinopec. The project involves the simultaneous construction of 32 100,000-cubic-meter crude oil storage tanks, playing a crucial role in safeguarding the nation’s strategic oil reserves. Through meticulous planning and scientifically sound execution, our company completed, on schedule, the fabrication and installation of 7,500 concrete bored piles totaling 63,000 cubic meters for Section III in just 190 days, with all results fully meeting design specifications.
Wison Offshore Engineering Equipment Base Project
The Wison Offshore Engineering Equipment Base project is located at No. 18 Weihai Avenue, Lüsigang Development Zone, Qidong City, Nantong, Jiangsu Province. Our company has completed approximately 200,000 meters of pile‑foundation construction across two contract sections.
The New Energy‑Specific Polyolefin Specialty Materials Project is located on Plot C3 of the Shanghai Chemical Industry Park. It is being developed through a new investment by Puxijing New Materials (Shanghai) Co., Ltd. Our company undertook the pile foundation works for Phases I and II, which commenced on April 23, 2024, and were completed in September 2024, with a total of 210,000 meters of prestressed pipe piles and square piles installed.
The Anhui Huayi Coal‑Based Polygeneration Fine Chemicals Project, a large‑scale integrated coal‑chemical facility with an annual capacity of 600,000 tons of methanol and 350,000 tons of acetic acid, is one of the super‑large projects through which Shanghai’s state‑owned Huayi Group has responded to the national strategic layout, entered Anhui Province, and joined the Yangtze River‑side industrial chain. The foundation system employs precast concrete pipe piles, totaling over 600,000 linear meters, and has garnered attention from leaders at all levels in both Shanghai and Anhui Province. Guided by the company’s meticulous planning and scientifically sound construction approach, the foundation works were completed with outstanding performance, earning the National Quality Engineering Gold Award for the 2012–2013 period.
The Senlan International Community Commercial Building A4‑2 project is located in the Senlan area of Shanghai’s Waigaoqiao Free Trade Zone. The main structure comprises five above‑ground floors, housing commercial spaces, community services, and sports facilities, while the three underground levels accommodate two levels of retail space and a three‑level parking garage. For this project, static‑pressure pipe piles are used for the two‑story section, whereas bored cast‑in‑place piles are employed in the three‑story section. The excavation pit covers an area of 33,118 m², with depths ranging from 11.3 to 16.65 m. Sequential full‑pit excavation is adopted. In the second basement level, the retaining system consists of row piles combined with triple‑axis jet grouting cutoff walls and two horizontal concrete bracing members. In the third basement level, the design features a diaphragm wall (with rubber waterstop joints), triple‑axis jet grouting wall reinforcement, and three horizontal concrete bracing members. In areas with elevation differences, the retaining system utilizes bored cast‑in‑place piles together with an ultra‑long triple‑axis cement‑soil jet grouting cutoff wall.
