Zhuhai Jiangmen has entered the "1-hour Economic Circle" and the integrated development of the Greater Bay Area is accelerating
2024-06-24
Steel giant dragon Tengwan District, Changhong lies on the wave frame and leads the way. Overlooking the Guangdong Hong Kong Macao Greater Bay Area, a series of cross sea super projects are becoming an important link connecting the urban agglomerations on the east and west sides of the the Pearl River Estuary, accelerating regional integration. Recently, the Huangmaohai Cross Sea Passage connecting Zhuhai and Jiangmen has achieved full connectivity and will be completed and opened to traffic by the end of this year. The Shenzhen Zhongshan Passage, which connects Shenzhen and Zhongshan, has also passed the handover inspection and is about to be officially opened to traffic. These two super projects, along with the completed and open Hong Kong Zhuhai Macao Bridge, Nansha Bridge, and Humen Bridge, together form a group of cross sea and cross river channels in the Greater Bay Area, thus accelerating out of the "one hour economic circle". It can be imagined that a brand new and collaborative Zhuxi will accelerate its rise, and on the journey of "rebuilding a new Guangdong", urban-rural and regional development will be more coordinated. Since June, good news about the construction of super projects in the Guangdong Hong Kong Macao Greater Bay Area has been constantly spreading. On June 19th, with the completion of the final steel box girder welding, the Huangmaohai Bridge was successfully closed, marking the full completion of the Huangmaohai Cross Sea Passage connecting Jiangmen and Zhuhai in Guangdong. The Huangmaohai Cross Sea Passage is the first cross sea passage project to commence construction after the release of the Outline Development Plan for the Guangdong Hong Kong Macao Greater Bay Area. It is also the western extension of the Hong Kong Zhuhai Macao Bridge. The total length of the project route is about 31 kilometers, and the length of the sea section is about 15 kilometers. There are two main bridges, Gaolan Port Bridge and Huangmaohai Bridge, set up. The Gaolan Port Bridge was completed on March 20th this year. Zhu Chao, Director of the Huangmaohai Cross Sea Channel Management Center, introduced that the builders spent 9 months "threading needles" in the climate changing Huangmaohai Sea area, overcoming many construction risks and technical difficulties such as navigation safety, typhoon defense, and special beam section installation, and ultimately achieving a closure deviation of less than 2 millimeters for the Huangmaohai Bridge. It is reported that the Huangmaohai Bridge innovatively adopted a "small waist" single column shaped cable tower in its design. In response to the difficulty of controlling the accuracy of cable tower construction, the builders have independently developed the overall lifting technology of the steel reinforcement skeleton of the 100 ton cable tower section and the double-layer adjustable lifting tool to control the docking error. The construction of each irregular cable tower section has been shortened from 12 days to 6 days, greatly improving construction efficiency. Just two days before the successful closure of the Huangmaohai Bridge, another super project also made significant progress. On June 16th, the Shenzhen China Channel passed the handover acceptance, marking the successful completion of various construction tasks for this world-class cross sea cluster project, which has undergone 7 years of preliminary preparation and 7 years of arduous construction. The project quality has passed the "big test". The Shenzhen China Highway is a major national project. The project integrates "bridge island tunnel underwater interchange", with a total length of about 24 kilometers, and is currently one of the most difficult cross sea cluster projects in the world for comprehensive construction. "Sigh at the small ones in the ocean.". Building a super project on the vast and desolate ocean is not an easy task! Crossing 11 fault structural zones, high runoff and severe siltation, located in areas with frequent typhoons, difficult construction safety assurance, high navigation safety risks when crossing the busiest water bodies in the world, and how to overcome the corrosion fatigue problem of the main cables of suspension bridges in high salt and high humidity environments are a long series of difficulties and challenges facing builders. Long winds and waves sometimes break. The builders overcame difficulties, overcame multiple world-class technological challenges, created the most cross sea projects, and fully promoted industrial and intelligent construction. They developed and formed 15 world first core materials, key technologies, and major weapons, including ultra-high strength main cable steel wire strands. The Shenzhong Channel project has also systematically innovated the construction technology of offshore large-span suspension bridges and the floating installation process of offshore ultra large scale sunken pipe joints, forming a "first-class technology". According to Song Shenyou, Director of the Shenzhong Channel Management Center, five breakthroughs and leading "Shenzhong Quality" have been achieved in the world's first bidirectional eight lane underwater tunnel, the world's largest offshore mid sea suspension bridge, and the world's first underwater hub interchange. A group of high-quality talents and innovative teams for the construction of cross sea transportation clusters have been cultivated, providing Guangdong experience and Chinese solutions for the world's cross sea channel projects. As a barrier, Jiangmen in Zhuhai has entered the "one hour economic circle". The the Pearl River Estuary has profoundly affected the industrial structure and economic development path of the urban agglomeration on both sides of the east and west. The super project of "turning a chasm into a path" has made the connection between urban agglomerations on both sides of the strait increasingly dense, bringing new opportunities for the coordinated development of urban agglomerations on both sides of the strait. As a super engineering construction unit, Deng Xiaohua, Chairman of Guangdong Provincial Communications Group, said that as a new "traffic backbone" and a key "horizontal" of the "A" shaped traffic network framework in the Guangdong Hong Kong Macao Greater Bay Area, the Shenzhen China Channel has shouldered the important mission of promoting better connection and integration of the east and west banks of the the Pearl River Estuary at the stage of self conception and design. With the opening of the Shenzhen China Channel, the "gold content" of the "golden inner bay" at the mouth of the the Pearl River River will be greatly improved, which will have a profound impact on the regional development pattern of the Guangdong Hong Kong Macao Greater Bay Area. After the completion and opening of the Shenzhen Zhongshan Corridor, the travel time between Shenzhen and Zhongshan has been shortened from 2 hours to less than 30 minutes, and the two places have joined hands to enter the "half hour economic and living circle". The opening of the Shenzhen China Channel will not only greatly facilitate the travel of residents in both places, but also promote the deep integration of the economy, culture, science and technology in the east and west sides of the the Pearl River Estuary. Connect the river to the sea. After the completion and opening of the Huangmaohai Cross Sea Passage at the end of this year, it will inject new vitality into the development of the Guangdong Hong Kong Macao Greater Bay Area. As a result, Jiangmen and Zhuhai will enter the "1-hour economic and living circle", with no need to detour along the entire highway. It will also strengthen the industrial transfer in Zhuhai and even the Guangdong Hong Kong Macao region, drive the economic development of Jiangmen Taishan and western Guangdong, and improve the industrial layout in western Guangdong. The Huangmaohai Expressway will also connect with the Hong Kong Zhuhai Macao Bridge, connect with the western coastal expressway, and officially form a coastal economic artery in Guangdong Province, improving the daily life of residents in western Guangdong and the Pearl River Delta region. The construction of this channel will further promote the integrated development process of the Guangdong Hong Kong Macao Greater Bay Area, achieving resource sharing, complementary advantages, and mutual benefit. Lin Feiming, Director of the Department of Transportation of Guangdong Province, said that super projects such as the Shenzhen Zhongshan Expressway and the Huangmaohai Expressway are vivid depictions of Guangdong's acceleration in building a strong transportation country. Their completion and opening to traffic will completely change the overall road grid of the the Pearl River Estuary, which is of great significance to the economic and social development of the Guangdong Hong Kong Macao Greater Bay Area. "Guangdong will use new quality productivity to improve the accessibility and service efficiency of the road network, promote the further improvement and smoothness of the expressway network along the Shenzhen China Corridor and surrounding areas, and provide efficient and safe 'hard connectivity' support for the development of the Great Bay Area." The "bridge economy" creates new opportunities for development. The space and time distance between cities on both sides of the Pearl River Estuary is shortening, while the flow of people, logistics, capital, and information is accelerating. Zhuhai, Guangdong Province is positioned as the core city on the west bank of the the Pearl River Estuary. With the promotion of the "Ten Million Project", a series of new plans for the coordinated development of the western the Pearl River River Estuary metropolitan area have been disclosed and new actions have been implemented, and the strategic effect of the western Pearl River is emerging. At present, the large ports, large petrochemical, large equipment, and large industries on the west bank of the Pearl River will become an important driving force for the future growth of the province, and it is high time for Guangdong to provide new support for high-quality development. Chen Yong, Secretary of the CPC Zhuhai Municipal Committee, said that Zhuhai will consciously assume the core responsibility of the starting point of the Western the Pearl River River strategy, take the responsibility of "leading geese" in guiding the development of the western Pearl River and western Guangdong, activate the "wild goose array effect", and play a core and leading role in driving the development of the western Pearl River area. As an important node city in the overseas Chinese capital and the Guangdong Hong Kong Macao Greater Bay Area, Jiangmen City has also ushered in a window and golden period of "bridge economy" with the completion of the Shenzhen China Highway and Huangmaohai Highway. Jiangmen has a land area that accounts for 1/6 of the Greater Bay Area, and is a large-scale industrial agglomeration area with the largest new layout area in Guangdong Province that can be developed on a large scale in a contiguous manner. "Some aspects of equipment manufacturing enterprises are not suitable for going upstairs and can only find places with sufficient land resources and space," said Tang Shanbin, Sales Director of Shenzhen Zhifenling Technology Company. "Jiangmen's construction of a 'first floor factory' has advantages.". Lin Yipan, Chairman and General Manager of Lihexing Company from Shenzhen, also sees this advantage: "Our R&D headquarters is located in Shenzhen, and production is in Jiangmen, which is very convenient. This is a win-win model for sharing." Smooth transportation leads to prosperity in all industries. The Zhuxi International Logistics Center in Heshan, Jiangmen City is accelerating its progress towards the goal of becoming an international logistics hub that sells and buys globally. "In recent years, we have promoted the extension of the port function of Jiangmen North Station, running rail water intermodal freight trains to Yantian in Shenzhen, Nansha in Guangzhou, and Gaolan in Zhuhai, and normalizing the operation of international freight trains such as China Europe, opening up a new land route for economic and trade exchanges between the western wing of the Pearl River Delta and Europe and ASEAN," said Pan Zhiyuan, manager of Jiangmen Zhuxi Logistics Development Co., Ltd. Chikan Overseas Chinese Ancient Town, with more than 680 century old arcades funded and designed by overseas Chinese, is the only overseas Chinese themed ancient town in China. the Kaiping Diaolou and Villages are the only world cultural heritage in Guangdong Province. Xu Fei, the CEO of these two projects, stated that with the completion of the Shenzhen China Channel and the Huangmaohai Channel, it will be more beneficial for tourists from Hong Kong, Macau, and the eastern part of the Greater Bay Area to experience a number of excellent cultural and tourism products in the central and western regions of the Greater Bay Area, such as the Chikan Overseas Chinese Ancient Town and Kaiping Diaolou, promoting communication and integration within the Greater Bay Area. "Nowadays, there are more and more tourists from Hong Kong and Macao in Chikan, and more and more young people are deepening their understanding of overseas Chinese culture and Lingnan culture through the story of the fusion of Chinese and Western arcade and watchtower, and getting to know the Chinese hometown of Jiangmen." Xu Fei said. Chen Anming, Secretary of the Jiangmen Municipal Party Committee, stated that Jiangmen has a comprehensive industrial foundation, rich and unique overseas Chinese resources, and comparative advantages are accelerating their transformation into high-quality development advantages, sharing more dividends in the integrated development of the Greater Bay Area urban agglomeration.
