Zhuhai-Macau Frontier Port Artificial Island of HZM Bridge
Address: South side of Gongbei Bay, Xiangzhou District, Zhuhai City
As the first construction project of the Hong Kong-Zhuhai-Macao Bridge, the artificial island reclamation area of Zhuhai-Macau Frontier Port Artificial Island of HZM Bridge reached 2.3897 million square meters, which is the largest of the four artificial islands of the Hong Kong-Zhuhai-Macao Bridge, and is equivalent to 300 football fields. It is divided into three functional zones: Zhuhai Port Management Zone, Macao Port Management Zone and Bridge Management Zone. It is the connection point of the main project of Hong Kong-Zhuhai-Macao Bridge and Zhuhai and Macao and is of great strategic significance.
In a time span of just over three years, Gree Real Estate has overcame many technical problems in offshore construction and created the Zhuhai-Macau Frontier Port Artificial Island , transforming a watery swath of ocean into a solid land mass, making the dream of building at sea a reality.
Ultra-high Standards
Meeting the Requirements of all 3 Regions
The combined scale of the bridge, island and tunnel of the Hong Kong-Zhuhai-Macao Bridge is unique and unprecedented. It has the world's highest technical standard - the service life must reach 120 years, and be able to withstand magnitude 16 typhoons, magnitude 8 earthquakes and collision impacts from a 300,000-ton tanker. The Zhuhai-Macau Frontier Port Artificial Island also put forth very high standards for planning, design and construction. In addition, the Zhuhai-Macau Frontier Port Artificial Island is in a unique geographical location connecting Zhuhai and Macao, and needs to meet the technical standards of Guangdong, Hong Kong and Macao simultaneously.
Revetments Comprising of More than 20,000 Square Arrays
In order to withstand the attack of wind and waves, the Zhuhai-Macau Frontier Port Artificial Island has a revetment of more than 6 kilometers on the side facing the South China Sea. It consists of more than 20,000 pieces of four-legged hollow square arrays, each weighing 3 tons, with a “break-wave” effect. Huge stones are also placed in the outer perimeter of the revetment to jointly form a solid line of defense.
The Best Soft Foundation Treatment
During the reclamation treatment stage, the Zhuhai-Macau Frontier Port Artificial Island adopted the “combined vacuum preloading” technology. The effect is best in various soft foundation treatments. While using vacuum to remove moisture from the soil, a heavy load is applied simultaneously from the top to exert pressure downwards, making the soft soil foundation more compact, allowing it to withstand the once-in-300-year-flood of the Pearl River estuary.
Demonstration Project
Zero Accident, Zero Pollution, Zero Casualties
Gree Real Estate rigorously managed the construction process in a scientifically manner. Under the premise of ensuring safety and quality, implementing civilized construction methods that are environment-friendly, and achieved excellent results in safe construction with “zero accident, zero pollution, zero casualties”. In June 2013, the project was rated as a ministerial level “Safe Construction Site” demonstration project by the Ministry of Transport.
After more than a thousand days and nights of hard work, the reclamation and foundation of the Zhuhai-Macau Frontier Port Artificial Island were completed above requirements, and became a demonstration project in the construction of the Hong Kong-Zhuhai-Macao Bridge.
Protecting the Chinese White Dolphin
The artificial island construction area of Zhuhai-Macau Frontier Port Artificial Island is located in the Pearl River Estuary and passes through the Chinese White Dolphin Ecological Zone. Regarding the protection of Chinese white dolphins, Gree Real Estate took effective measures during the construction process such as dredging, transporting stones, and filling to reduce seawater turbidity pollution and avoided the deterioration of environmental conditions that would impact the feeding and survival of the white dolphins.
Monitoring of Ocean Indicators
In order to reduce the damage caused by construction to the marine environment, Gree Real Estate requested garbage bins and waste oil collection bins to be installed in all construction vessels, and sign a garbage recovery agreement with a professional ocean waste recycling company to regularly recycle garbage and oil. Concurrently, a third-party marine environmental monitoring unit was employed to perform long-term monitoring of various indicators.
