For concrete precast segments of superstructure of railway or road bridge constructions such as viaducts or multi-span bridges, #launchinggantries designed by HL-KATTOR are reliable beam launching equipment to deliver economic and rapid #constructionmethods for infrastructure development.
Optional #overhead or #underslung#bridgelauncher. Bridge decks can be constructed span by span, or by using longitudinal pre-stressing cables that run the entire span length to stress each segment together.
"Bridging the Future: Swift and Strong with Precast Segmental Box Girders!"
Launching precast segmental box girders involves assembling pre-fabricated segments to form a bridge deck. These segments are manufactured off-site, transported to the construction site, and lifted into place using cranes or launching gantries. Each segment is precisely positioned and connected using post-tensioning tendons to ensure structural integrity. This method offers numerous advantages, including faster construction times, improved quality control, and reduced on-site labor. It is particularly beneficial for projects with challenging site conditions or tight construction schedules. Precast segmental box girders are commonly used in highway bridges, viaducts, and overpasses, providing a durable and efficient solution for modern infrastructure projects.

SILVERTOWN TUNNEL CONNECTIONS COMPLETED
Riverlinx CJV has completed construction works for the connections between the open cut approaches and the bored section of the Silvertown Tunnel.
The final transition section of the tunnel was cast in Silvertown on April 11, completing the work to connect the northbound and southbound tunnel structures from the Silvertown portal to the Greenwich portal.
A complete transformation of the tunnel shape was needed to connect the circular TBM-constructed tunnel to the in situ concrete arch-shaped cut and cover tunnels.
To construct the four transitions, a self-propelled, self-erecting formwork was used, nicknamed “The Crab”.
This 70-tonne tracked structure was moved into position and folded out to create the unique shape using hydraulic rams. The Crab then acted as a temporary structure for the installation of steel reinforcement before concrete was placed and allowed to cure. Once the concrete had cured sufficiently to be self-supporting, the machine folded the shutters inward for transport through the bored tunnel to the next transition location.
The final of eight cross-passages is now ready for fit-out

🚇 Check out this in-depth look at the prefabrication construction technology of U-shaped beams for subway viaducts! 😎
The U-shaped beam is an advanced and novel concrete beam structure that not only has an ideal and beautiful appearance but also significantly reduces the overall structural height and construction complexity of subway viaducts. 👏
This article covers various aspects of the construction process, including prefabricated beam platform construction technology, prestressed pipeline technology, U-shaped beam reinforcement treatment technology, formwork construction technology, concrete construction technology, and concrete curing technology. 🛠️
With strict quality control and a focus on safety and stability, these technologies are essential for the successful construction of metro viaducts. 💪
Let's all focus on these advanced construction technologies and work together to contribute to the development of urban transportation infrastructure. 🚝🚉

Are you planning your next bridge project?
Our innovative vision is based on a commitment to the most advanced technology, such as the balanced cantilever method, which consists of constructing the bridge deck, starting from the piers, with mobile formwork carriages.
First, the first segment on the pier, known as the pier segment, is built on-site. The balanced cantilever formwork carriage supports the weight of the segment being built. Half of the structure is supported and fastened to the previous segment; the rest is cantilevered.
The most efficient solution for:
✅Bridges with spans up to 200 m.
✅There are riverbeds, intersections between several roads, and land where railways and roads converge simultaneously.
✅The pier heights exceed 50m.
System Advantages:
✅The work is performed in a reduced area on the deck and doesn’t interfere with traffic.
✅Flexibility: the ability to build decks with variable depths and distances between spans.
✅Hydraulic system for leveling and forward movement of the CVS carriage, reducing the labor force needed and construction times.
✅High load-bearing capacity: Larger segments can be made.
