The connection is intended to significantly accelerate the integration and development of the urban agglomeration in the Greater Bay Area and will also reduce travel time from Shenzhen to Zhongshan to around 30 minutes.

The work for the huge structure is even more challenging as the work for the Hong Kong-Zhuhai-Macao Bridge and has already begun. As was the case with the Hong Kong-Zhuhai-Macao Bridge, several machines from the Bauer Maschinen Group are also used in this prestigious major project.

CCCC-Second Harbor Engineering Co. is constructing the approximately 4km long section S04. The main works include the eastern tower and the eastern anchorage of the main part of the Lingdingyang Bridge. This suspension bridge with its three fields - two of them with a length of 580m and a 1,666m long midfield - is a key project of the Shenzhen-Zhongshan link.

A special feature is that the section S04 is completely offshore, i.e., above the water. Thus, the anchorage for the Lingdingyang Bridge must be established below the water level. For this purpose, CCCC-Second Harbor Engineering Co. has constructed an 8-shaped diaphragm wall with a diameter of 2 x 65m and a width of 1.5m using a Bauer BC 40 trench cutter and a Bauer MC 96 duty-cycle crane. The 79 panels vary in depths from 48 to 66m and are embedded in granite.

In addition, the company Guangdong Hualiang Foundation Engineering Co. Ltd is using proven Bauer technology for its work: a BC 40 trench cutter, an MC 96 duty-cycle crane and a BG 38 rotary drilling rig have already reached their place of use and further equipment from Bauer is already on the way.
