"Civil Engineering Watching - Infrastructure Encyclopedia: Collection of Civil Engineering Structures Photos" is a portal site for images and information about civil engineering structures that form social infrastructure facilities. Recently, we have published photos and articles about the "Leonardo da Vinci Bridge." The "Leonardo da Vinci Bridge" was constructed in the 1950s in Sasso Marconi, Italy. After more than 70 years of intensive use, it was closed to traffic in 2021 due to severe damage, and renovation work has begun. In addition to the "Leonardo da Vinci Bridge," various civil engineering projects, photos, and articles related to civil engineering are also featured, so we hope you will take a look.

PERI products are used on construction sites around the world. This time, we would like to introduce the "Tassonaro Railway Bridge Renovation Project" in Italy. This historic railway bridge, spanning the Tassonaro River, underwent extensive renovation work in 2023. The reason for the renovation was the cracking of the concrete due to ground subsidence. Built in the 1930s with stone and white marble, this railway bridge is approximately 200 meters long and consists of nine arches. It survived both bombing and sabotage during World War II. To protect the bridge from seismic activity caused by the clay embankment, deep foundations were excavated down to 35 meters below the river surface during construction. Structural renovations were carried out inside the nine arches of the railway bridge using concrete and rebar. To ensure the partial preservation of the structure, PERI developed a custom special solution that combined multiple products and provided support for both the planning phase and on-site construction. PERI products: 1. VARIO GT24 (wall formwork) 2. RUNDFLEX (circular wall formwork) 3. PERI UP (modular scaffolding system) PERI Japan Co., Ltd.

"Civil Engineering Watching - Infrastructure Encyclopedia: Collection of Civil Engineering Structures" is a portal site for images and information about civil engineering structures that form social infrastructure facilities. We have recently published photos and articles about the "Saale Valley Bridge." The "Saale Valley Bridge" was constructed at the border between Saxony-Anhalt and Thuringia, in Bad Kösen, Naumburg. Boasting an impressive height of up to 60 meters, this structure spans a total length of 1.2 kilometers and a width of 12.5 meters, harmoniously blending with the surrounding landscape designated as a nature reserve. In addition to the "Saale Valley Bridge," various civil engineering projects, photos, and articles related to civil engineering are also featured, so we hope you will take a look.

PERI has started handling the concrete sensor "SONO HUB (Water/Cement Ratio Sensor / Web Application)" that can be used during concrete pouring at construction sites. By using "SONO HUB (Water/Cement Ratio Sensor / Web Application)," you can quickly and accurately measure the unit water content of fresh concrete on-site. The product composition of "SONO HUB" consists of the following two components: 1. "Portable measuring device that displays measurement results" 2. "Shovel-shaped measuring probe" Furthermore, by utilizing the measured data with the "Web Application (Cloud Application)," you can visualize, analyze, and create reports on the data. The use is not limited to construction sites. For example, in laboratories or facilities that manufacture concrete products, you can maximize workability and manage unit water content without sacrificing quality. *For more details about this product, please feel free to contact us.
