HZMB update

The first pair of precast shells for the pile caps of the Hong Kong- Zhuhai-Macau Bridge (HZMB) was installed in December with a 300t floating crane. The shells, fabricated in China, weighed 210t, making a total lift load of 230t with the support system and access walkway. They were the first in a long series of 148 shells that will be installed. The support system has been designed to avoid high-risk diving works. Temporary support beams are clamped to the shell walls with VSL Stress bars and rest on king posts until the concrete stitch between the shell and pile head reaches 30MPa. The shell is then ready for internal pile cap works.

Improve competitiveness in Vietnam

The VSlab system has provided a very competitive solution for the Sunrise City project in Ho Chi Minh City, Vietnam. Sunrise City is developer Novaland's first project to use post-tensioning. VSL worked with the developer and its consultant throughout the design stage. Building the four 33-storey towers has required 94,400m2 of post-tensioned flat slabs. VSL installed the VSlab to a six-day typical cycle. Use of VSlab gave an efficient floor design, eased installation and minimised the manpower required.


Quieter crossing in Slovakia

Installation of a post-tensioned deck was chosen as a quieter alternative than the traditional steel for a rail bridge crossing the Váh River in an urban area of Trenčín in Slovakia. The new bridge is being built as part of the upgrade of the Nové Mesto nad Váhom – Púchov railway. The project for Slovak Railways is being co-financed by EU funds and built by Bögl and Krýsl to a design by Betoning. The seven-span viaduct is 340m long and is being constructed by the balanced cantilever method. VSL is supplying tie bars and post-tensioning, together with PT-Plus® ducting.
