China has been investing heavily in the expansion of its infrastructure for many years. This also includes the expansion of the rail network for local transport. Only recently, the National Commission for Development and Reform approved a comprehensive programme for the further development of several metro and subway lines in large cities, including Beijing, Tianjin, Shenzhen and Ningbo.
As a specialist in fastening energy systems, communication systems, fire protection technology, evacuation bridges and wind and hydropower systems, the fischer Group is actively involved in many of these projects with its Chinese national company. For example, fischer has now also been involved in several projects to expand the Beijing S-Bahn (metro) network, namely on lines 6, 8, 9, 10, 14, 15, 16, on the airport line and also on the S1 subway line.The company has previously been involved in the construction and expansion of railways in Beijing, Shanghai, Guangzhou, Shenzhen, Wuxi, Wuhan and other metropolitan cities and has gained a leading position and extensive experience in this area.
One of the most commonly used products is the FZA cyclone undercut anchor from Fischer. In Chinese rail projects, this anchor is primarily used for fastening brackets for overhead power cables, especially brackets for overhead power lines. With its special undercut technology, the anchor ensures positive connections and maximum safety. After it has been inserted into the drill hole, the expansion sleeve is driven over the taper with the FZE Plus setting tool and the undercut drill hole is filled form-fitted.
The FHB II high bond anchor from Fischer is used to anchor the important evacuation bridges in the tunnel tubes, either with the appropriate injection mortar or the quick and easy-to-use mortar cartridges. When setting this bolt, which is available in a short and a long version, the cones of the anchor rod are pulled into the mortar shell, which tensions against the hole wall.
