Trelleborg to supply the world's widest immersed tunnel

The link, which connects Shenzhen and Zhongshan, is 24 kilometers in length and consists of two artificial islands, two bridges and a two-way, eight-lane tunnel that has a width of up to 46 meters, making it the largest and widest immersed tunnel in the world upon completion in 2024.

We are delighted to have been awarded the contract for the ShenZhong Link, yet another high profile infrastructure project, central to China’s 13th Five-Year Plan (2016-2020), and look forward to yet again working closely with CCCC Fourth Harbour Engineering Co., Ltd. The award of this contract is testament to our unrivalled industry expertise and undisputed reputation as a world leader in the design and manufacture of advanced, high-performance tunnel sealing solutions.

Trelleborg will supply its Gina gaskets and Omega seals, which are to be used between the sectional elements of the ShenZhong Link’s immersed tunnel to prevent water ingress due to external water pressure.

We’ll leave you with the kind words of Zhang Wensen, Project Manager at CCCC: “Following the success of our partnership for the construction of the Hong Kong Zhuhai Macau Bridge, we had no hesitation in turning to Trelleborg once again. Trelleborg’s unrivalled engineering expertise ensured that the company was a natural choice to supply the project. We look forward to further strengthening our existing relationship.”

Furthermore, Zhong Huihong, Vice Director at ShenZhong Link Administration Center, added: “I’m delighted that we are able to cooperate with Trelleborg for yet another ground-breaking project, such as The ShenZhong Link, which will prove extremely valuable to the future of the Guangdong-Hong Kong-Macao Greater Bay Area. Trelleborg is the leading global supplier of tunnel seals and so we are convinced that once complete, the ShenZhong Link will be undoubtedly one the world’s finest infrastructure projects.“
