Qingdao Jiaozhou Bay secondTunnelsMain lineTunnelsYesChina Railway ConstructionA major project designed by the Fourth Railway Institute and undertaken by the 14th Bureau of China Railway, it aims to connect the main urban area of Qingdao with the national new areaQingdao West CoastNew. this oneTunnelsIt is designed for speeds of up to 80 kilometers per hour and has a total length of 1748 km of which the main lineTunnelsUp to 1437 km, covering up to 995 km of sea area. This marks the largest and longest submarine road in ChinaTunnelsThe main body officially started the shield crossing operation.
second in Jiaozhou Bay, QingdaoTunnelsThe main line of the southern line of the projectTunnelsAt the shield excavation site, the builders are in full swing for construction work. They meticulously inspected the "Haitian".Shield machineto prepare for the start of the tunnelling. This hugeShield machineQuietly waiting for the next voyage, it is like a giant beast sleeping at the bottom of the sea.
Construction of an undersea roadTunnelsUndoubtedly a difficult task. First of all, the seabedenvironmentComplex and changeable, to carry out construction in the changing water flow, sand and other natural factors, the requirements for technical force and construction process are extremely high. Second, the safety of waterway traffic is an important consideration that needs to be properly designedTunnelsTransportationrules and facilities, ensureTunnelssafe operation. In addition, undersea roadsTunnelsmaintenance is also a problem, requiring the development of a special plan to deal with seawater erosion andTunnelsWear and tear of equipment.
In order to meet these challenges,China Railway ConstructionThe Fourth Iron Institute and the 14th Bureau of China Railway have actively introduced advanced shield technology. Shield machineThe application greatly improves the efficiency and quality of construction, and reduces the number of toenvironmentimpact. Shield machineBy constantly advancing, willTunnelsPiece by piece, forTunnelsThe crossing provides a solid foundation. At the same time, strict control measures were also adopted during the construction process to ensure construction safety and quality.
With our countryEconomyThe rapid development of theTransportationThe demand is growing day by day. And the bottom of the seaTunnelsAsTransportationGroundbreaking projects in the field provide a new option for connecting cities.
First of all, the seabedTunnelswill help ease the cityTransportationPressure. Qingdao Jiaozhou Bay secondTunnelsThe construction will effectively connect the main urban area of Qingdao and the national new areaQingdao West CoastThe new area provides a more convenient channel for ** and logistics between the two areas. This not only reduces road congestion, but also optimizesTransportationflow, improve the wholeTransportationEfficiency.
Secondly, the seabedTunnelsThe construction will promoteEconomyDevelop. The main urban area of Qingdao andQingdao West CoastNew districts are allEconomyProsperous core area,TunnelsThe opening of the two places will be conducive to the interconnection of the two places and further promotedEconomycooperation and development. TransportationThe convenience will attract more investment and enterprises to settle down, driving the local areaEconomyof take-off.
And finally, the seabedTunnelsThe construction will also have an impact on the ecologyenvironmentMake a positive impact. TunnelsLand can be reducedTransportationYesenvironmentto reduce the emission of emissions and protect the ecologyenvironmentto improve the level of sustainable urban development.
Under the seaTunnelsThe construction of our countryTransportationIt is an important attempt at the development of the field and a breakthrough in the field of technology. Through such attempts and breakthroughs, we can continue to accumulate experience and improve technology for more seabeds in the futureTunnelsConstruction provides reference and guidance.
At the same time, the bottom of the seaTunnelsWe also need to pay attention to the protection of the oceansenvironment。withTunnelsThe impact on marine organisms and ecosystems will gradually emerge. Therefore, in the process of construction, we need to strengthenenvironmentConservation measures to minimize the impact on marine ecology and ensure the sustainable development of marine ecosystems.
Overall, Qingdao Jiaozhou Bay is secondTunnelsMain lineTunnelsThe construction of the submarine road in our country was openedTunnelsA new chapter in construction. This is a challenging project that will open up between the citiesTransportationConnectivity offers new options to facilitateEconomyAt the same time, we need to pay attention to ecologyenvironmentprotection. I believe that in the future development of our country's seabedTunnelsThe construction will become more and more mature and perfect, forTransportationDevelopment andEconomyprosperity to make a greater contribution.
