In the Chinese city of Suzhou, work has been completed to create a unique retaining wall to strengthen the coastline of one of the water channels. What makes it special is that the wall was erected using construction 3D printing technology. With a length of 500 m and a height of several meters, it is by far the largest structure of this type in the world.
Suzhou is a canal city built on a system of natural streams and man-made canals. There are many bridges and parks, decorative structures and gardens, but there is practically no capital construction. The conditions in the city are such that it is extremely risky to use heavy equipment and carry out large-scale excavation work. However, the main city canal needs protection from erosion for a long time, for which it was necessary to strengthen the earthen banks with a reliable wall.
The main contractor was the Winsun company, which managed to build a wall literally along the edge of the stream, occupying a minimum of area. This is an inclined structure with a complex relief, it must extinguish the energy of waves in bad weather and keep the earthen slopes from destruction. At the same time, the wall, like its ancient predecessor, the Great Wall of China, is intended to serve as a symbol of the power of the nation and decoration of the city.
Representatives of the Winsun company noted that the use of 3D printing allowed them to significantly reduce the cost and time of building the wall. In addition, almost all the work was done by automatic devices, for this it was not even necessary to equip a full-fledged construction site, they cost minimal efforts. And it is obvious that this is only a debut - after the success in Suzhou, similar projects will be deployed throughout China.
