June 30 at 3 p.m.，The Shenzhen-Zhongshan Bridge was officially put into trial operation.，This world-class cross-sea cluster project was successfully completed.，Painting the Golden Inner Bay of the Pearl River Estuary“A”A key horizontal line of that glyph traffic network skeleton。Liugong Owim Company after Hong Kong-Zhuhai-Macao Bridge、After the Nansha Bridge，Contribute again to the transportation infrastructure construction of the Pearl River Estuary with the solution of prestressed system，Helping the Integration of Guangdong-Hong Kong-Macao Greater Bay Area。

After seven years of preparation、The Shenzhen-Medium Passage, which has been built for seven years, is a national highway network.G2518 Key Control Project across the Pearl River Estuary，Located between the Humen Bridge and the Hong Kong-Zhuhai-Macao Bridge，From Shenzhen Airport Interchange，Westward across the Lingdingyang Sea Area，Connect with Nanzhong Expressway through Wanqingsha Interchange，Landing at Ma'an Island, Zhongshan City，Docking with Zhongkai High Speed，The total length is about 24 kilometers.，Set“Bridge-Island-Tunnel-Underwater communication”In one，It is one of the most difficult cross-sea cluster projects in the world.。

From east to west, the Shenzhen-Zhongdao Passage is mainly composed of artificial islands in the east.、The undersea tunnel、West Artificial Island、Navigable Bridge in East Africa、Shenzhen-Zhongshan Bridge、A navigable bridge in West Africa、Zhongshan Bridge and Wanqingsha Sea-Crossing Bridge，The project includes the world's first two-way eight-lane undersea tunnel.、The world's largest span, full offshore suspension bridge and many other world's largest.。
Shenzhen-Zhongshan Bridge（Formerly known as Lingdingyang Bridge）It is the main navigable bridge of the Shenzhen-Medium Passage across the Lingdingyang Waterway and the South Longxue Waterway.，Double-tower three-span continuous full-floating system is adopted，It is the world's largest span steel box girder suspension bridge in the sea and the world's highest navigation clearance cross-sea bridge.。The body of the Sota Tower is in the shape of a door.，The main girder is a flat streamlined integral steel box girder.，Offshore super-large gravity anchorage scheme is adopted for the anchorage.，2000 developed by Liugong Owim CompanyMPaLevel multi-strand finished cable anchorage anchoring system。Anchorage is the key component of suspension bridge.，It is used to anchor the main cable。The Shenzhen-Zhongshan Bridge is located in the east.、West two anchorages，A single area is equivalent to 17 international standard basketball courts.，Weight about 1 million tons，It is the world's largest suspension bridge anchorage in the sea.。2000 developed by Liugong Owim CompanyMPaLevel multi-strand finished cable anchorage anchoring system，It can bear all the loads from the superstructure of the bridge.，But also can reduce that size of the structure.，Beneficial to full offshore application，This project is the first engineering application of this high strength multi-strand finished cable anchorage.。
For key projects such as the Shenzhen-Medium Passage，Liugong Owim also has a number of products and technology applications.，Including pre-stressed anchorage system products、OVM-XFPBAnisotropic steel friction pendulum seismic isolation bearings、1000tClass cable crane，And steel box girder incremental launching construction services.。
2000MPaLevel multi-strand finished cable anchorage anchoring system
Time returns to November 9, 2022.，With the last section of steel box girder pushed in place，The steel box girder incremental launching operation in the west anchorage area of Shenzhen-Zhongshan Bridge undertaken by Liugong Owim Company has been completed.。It is reported that，This incremental launching construction is the first attempt in open sea area in China.、Super-high buttress、Extra large span、Multi-point synchronous continuous incremental launching of super-large tonnage steel box girder，The separate walking pushing system and computer integrated control of Liugong Owim Company are adopted.，The steel box girder weighing thousands of tons is pushed forward by the alternate action of the walking device and the jacking Jack.，And pas through a deviation rectifying deviceRealize accurate positioning of steel box girder。
Back in the 1990s,，Liugong Owim Company participated in the construction of the Humen Bridge at the mouth of the Pearl River.，Provide prestressed anchorsSolid system、Anchorage anchoring system、High-speed hydraulic lifting equipment and other products。Whampoa Bridge opened to traffic in 2008，Nansha Bridge put into operation in 2019（Formerly known as Humen Second Bridge），All of them were built by Owim Company.。Hong Kong-Zhuhai-Macao Bridge completed and opened to traffic in 2018，Anchor system of large-diameter prestressed high-strength deformed steel bar provided by Liugong Owim Company、OVMIntelligent seismic isolation rubber bearing、Hydraulic Positioning System for Steel Box Girder、Prestressed anchorage system and other four key technologies and products，Realize offshore assembly and installation of bridge pier，Escort the safe operation of the bridge for 120 years。
After the opening of the Shenzhen-Zhongshan Bridge，The journey from Shenzhen to Zhongshan is shortened from two hours to less than 30 minutes.。Future，Liugong Owim will continue to focus on the development of prestressing technology.，Deepen the field of civil engineering construction，Solve industry problems，Provide more system solutions for prestress related fields。
