Following the Shenzhen-Zhongshan Link and the Huangmaohai Cross-sea Passage, the Guangdong-Hong Kong-Macao Greater Bay Area(GBA) is gearing up for the completion of another megaproject, the Lion Ocean (Shiziyang) Channel, as the year draws to a close. On December 20th, Guangdong Transportation Group announced that a key component of the Lion Ocean Channel project, the core filling construction of the East Anchorage of the Lion Ocean Bridge, has been successfully completed.

The Lion Ocean Bridge, the centerpiece of the channel, is designed as a double-deck steel truss suspension bridge with a main span of 2,180 meters. Upon completion, it is set to break five world records, including the longest main span for a suspension bridge, the number of lanes, and the height of the main towers, making it one of the most technologically challenging and intricately constructed bridges in the world. The anchorages, crucial for securing the main cables of a suspension bridge, directly impact the bridge's safety. The Lion Ocean Bridge features two anchorages, with the East Anchorage designed in a circular gravity style, reaching a total core filling height of 21.5 meters. Starting from July 8th of this year, after 164 days of relentless effort, the project team has completed the pouring of 192,000 cubic meters of concrete, totaling 476,000 tons of core filling, equivalent to the weight of six large aircraft carriers. A single continuous pour reached 18,000 cubic meters, setting a new engineering record.

With the completion of the East Anchorage's core filling, the West Anchorage is also in its final stretch, expected to be finished by the end of December. The successful construction of both anchorages will mark the transition of the Lion Ocean Channel's construction into the upper structure phase. Once completed, the project will open a new corridor for the integrated development of the eastern and western banks of the Pearl River Estuary, playing a significant role in promoting the integrated and high-quality development of the Pearl River Estuary in the GBA and in creating a "golden inner bay" of 100 kilometers around the Pearl River Estuary.

大湾区又一超级工程“上新”了

继深中通道、黄茅海跨海通道后，粤港澳大湾区又一超级工程狮子洋通道项目年底冲刺再“上新”。12月20日，广东交通集团发布消息，狮子洋通道项目关键性控制工程——狮子洋大桥东锚碇填芯施工顺利完成。

狮子洋大桥是狮子洋通道的核心工程，主桥采用双层钢桁悬索桥设计，主跨达2180米，建成后将刷新悬索桥主跨跨径、车道数量、主塔高度等五项世界纪录，是目前世界上技术难度最高、建造工艺最复杂的桥梁之一。而锚碇作为固定悬索桥主缆的重要构件，其施工质量直接决定桥梁安全。狮子洋大桥设置东西两个锚碇，东锚碇采用圆形重力式设计，基础填芯总高度达21.5米。从今年7月8日开始填芯施工，经过164天连续奋战，项目团队完成了19.2万方混凝土浇筑，总计填芯47.6万吨，相当于6艘大型航空母舰的重量。单次连续浇筑量高达1.8万方，创造了新的工程纪录。

随着东锚碇填芯的完成，西锚碇也已进入最后冲刺阶段，预计12月底完成。东西两侧锚碇的顺利建成，将标志狮子洋通道的建设进入上部结构施工阶段。项目建成后，将为珠江口东西两岸融合发展开辟新通道，对推动湾区珠江口一体化高质量发展、打造环珠江口100公里“黄金内湾”具有重要意义。
