Tunnel construction in a pumpedstorage
power station is characterized by low mechanization, poor operating
environment, high safety risk, low construction efficiency, and other factors.
Hence, a compact tunnel boring machine (TBM) for the construction of tunnel
with an ultrasmall turning radius is developed. The need for a tail shield, an
auxiliary thrust cylinder, and a segment erector is eliminated by the usage of
a doubleshield TBM, and an integrated TBM is designed
in combination with the open TBM anchor net spraying support system.
Furthermore, the Vshaped propulsion system design,
cutterhead thickplate forging technology, small cutterspacing design, combined wearresistant protection
design, compact machine design, beltconveyor
adaptability design for an ultrasmall turning radius, integrated belt conveyor
design, remote operating system design, etc., are incorporated. The obtained
research results have been successfully applied to the construction of the
drainage corridor of the Wendeng pumpedstorage power
station.
