Construction of highways to nuclear plants on soft soil-Chinese invention

High Vacuum Densification Method (HVDM) is offered by Geoharbour group , China. Using this technology, the firm reclaimed land, constructed highways to nuclear power plants. Details :

In recent limited years, over 20 inventions have been proposed by the Company and approved by the state intellectual authority, including HVDM Soft Soil Treatment Method (ZL01127046.2), Surcharge Preloading Combining HVDM (ZL200410014257.9) and Composite Foundation Combining HVDM (ZL200510134966.5), etc. These inventions are options for site treatments of varied geological conditions and requirements. Advancements have been made with regards to concepts, calculations, construction specifications and field tests. Inventions have obtained PCT certificates and registered in over twenty countries.

The Challenge: How to construct overpass over a busy high speed rail track in Wuhan city. Traffic cannot be halted and overpass has to be 256m long weighing 17,000 tonnes spanning 11 rail lines. Engineers in China built the overpass outside the rail lines and rotated it 106 degrees on a 15 metre axis to position it above running trains and it took just 90 minutes.
