Earth Anchor for Construction

The traditional construction technology needs lots of temporary supports to build girders, which inevitably causes serious environmental impact and traffic disruption. For reducing traffic disruptions, the temporary earth-anchor method builds temporary earth anchor blocks to enable a construction sequence that is similar to a conventional suspension bridge. 

However, the building of the earth-anchor also damages the surrounding environment and produces pollution. To avoid traffic disruptions, the temporary stayed cables technology uses temporary stayed-cables to erect girder segments, just as a cable-stayed bridge, and these stayed-cables aren’t removed until the main cables and hangers are erected. 

Although the technology reduces both environmental impact and traffic disruption, the use of expensive temporary structures (lots of stayed cables and heightened segments of the pylon) increases onsite construction cost and time.
