On October 23, 2018, President Xi Jinping: "I announced that the Hong Kong-Zhuhai-Macao Bridge was officially opened."
At the moment when President Xi announced that the Hong Kong-Zhuhai-Macao Bridge was officially opened, we are proud to be responsible for the island tunnel project (41m vertical drainage channel: plastic drainage board installation) for the main project of the Hong Kong-Zhuhai-Macao Bridge.
The reason why foreign media pay special attention to the Hong Kong-Zhuhai-Macao Bridge is actually because of one word: "Difficult".
The huge amount of engineering and the complicated construction conditions are not encountered in similar projects in the world.
It lasted for 9 years,
The Hong Kong-Zhuhai-Macao Bridge has been praised by the British "Guardian" as "one of the Seven Wonders of the New World".
Officially completed across the board.
At this point, Hong Kong and Zhuhai things, Changhong lying wave, Tianzhu north and south, the road is unimpeded.

As the main project of the Hong Kong-Zhuhai-Macao Bridge Island Tunnel Project
41m vertical drainage channel: construction unit for plastic drainage board installation
On the busiest waterway in the ocean
Writing the miracle of world bridge construction.
◆ It is currently the longest cross-sea bridge in the world.
◆It connects Hong Kong, Zhuhai and Macau
◆ Created more than 400 new patents and 7 of the world's best in the construction of the bridge.
◆ Island Tunnel Project is the control project of the entire Hong Kong-Zhuhai-Macao Bridge.
◆ The total length of the island tunnel project is 7440.5m, including the 5664m immersed tunnel, two offshore artificial islands with an area of 100,000m2, and a bridge with a length of about 800m. The island tunnel project adopts the design and construction general contracting mode.
◆ Processing area: 4,617,523 meters.
◆Treatment plan: use drainage board to preload and combine well point precipitation.
◆On May 8, 2011, the first steel cylinder and vibratory hammer power system of the West Artificial Island of the Hong Kong-Zhuhai-Macao Bridge Island Tunnel Project was successfully transported to Zhuhai by the No. 28 ship. The X48 steel cylinder is 40.5 meters high, 22 meters in diameter and weighs 450.4 tons.
◆ Steel cylinder is an important water stop structure for artificial island enclosure. It is designed to set the top elevation +3.5m. It is the first water project of Gongdao. The steel cylinder is designed with a dedicated vibration sinking system. The vibration-sinking system consists of 8 American APE-600 vibratory hammers with a self-weight of 500T. The 1600T lifting hammer is used to lift the vibration and sinking system. The 24 hydraulic chucks placed on the resonant beam are used to lift the steel cylinder to the design position for vibration. sink.
◆The 61 steel cylinders of the artificial island of the Hong Kong-Zhuhai-Macao Bridge Island Tunnel Project, such as the same string of necklaces, enclose a “mussel”-shaped ellipse with an area of 100,000 square meters on the sea. The steel cylinder of the West Artificial Island is 22 meters in diameter, with a maximum of more than 50 meters and a weight of more than 500 tons.
◆ There are a total of 52477 drainage boards in the West Artificial Island. The depth is about 40-46 meters deep, which is extremely difficult to construct.
◆ Since the first board machine started operation on November 1, 2011, the Sunzo Project Department has invested 5 pieces of equipment in a cross-construction manner. On December 7th, 900 sets of drainage boards were installed on a single equipment day. The maximum record of 3396 items accumulated in 5 devices per day. As of December 10, 2011, the construction of the plastic island of Xi'an Island was completed, and the construction task of the drainage board was completed ahead of schedule. Strive for time for customers and get unanimous praise from the media and the industry.
◆The Hong Kong-Zhuhai-Macao Bridge Island Tunnel East/Western Artificial Island is like a two-leaf boat floating on the surface of the ocean. The two bridges connecting the main bridge of the Hong Kong-Zhuhai-Macao Bridge, such as the long dragon, look magnificent.
◆ Only professional can create unique value
