On March 19, the cutter plate of the large-diameter hard rock TBM exported to Australia by China Railway Equipment slowly rotated, marking that the construction of the Snowy Hydro 2.0 project in Australia has officially entered the shield construction stage.
construction stage.
With an excavation diameter of 11.09 meters and a total length of 137 meters, this equipment is the first large-diameter hard rock TBM exported from China.The Snowy Mountains Project, to which this equipment is applied, is the Snowy Mountains Inter-Regional Water Transfer Project in Australia, one of the world's large-scale inter-basin and inter-regional water transfer projects. After the completion of the project will be the existing Snowy Mountains Hydroelectric Project power generation capacity increased by 50%, to the national power market to increase the supply of renewable energy 2000 megawatts. It will make an important contribution to environmental protection and sustainable development.
The tunnel of Snowy Hydro 2.0 project in Australia has a maximum depth of 723 meters, a horizontal turning radius of 500 meters, a maximum gradient of -9% in the boring section, and passes through the strata of siltstone and sandstone with a maximum strength of 160 MPa. Combined with the geological condition of the rock formation and the local standard of Australia, the designers of China Railway Equipment conducted repeated reviews and demonstrations, overcame many difficulties and challenges, and guaranteed the high quality production of the equipment through the refined management and organization, which met the project requirements and the local standard of Australia, and gained the high recognition of the customer and the owner.
In order to make the equipment put into the construction as soon as possible, the service team of Snowy Mountain Project of China Railway Equipment overcame the complicated and severe overseas epidemic situation and traveled to Australia to provide technical support. In the next step, the on-site service personnel of China Railway Equipment will continue to provide strong guarantee for the safe, smooth and efficient digging of the equipment with high quality and high efficiency with high sense of responsibility and rigorous working attitude.
