Abstract
The invention relates to a mud-resisting high-strength cable for a shield machine. The mud-resisting high-strength cable for the shield machine comprises control cable cores, a ground cable core and main insulation cable cores, wherein the three main insulation cable cores equationally form the cable; the two control cable cores and the ground cable core are entrained among the three main insulation cable cores respectively; the main insulation cable cores, the control cable cores and the ground cable core form the cable according eight-time pitches and then are wrapped with non-woven fabrics to form a wrapping layer; a first chloroprene rubber base inner sheath is extruded outside the wrapping layer; a first semi-conductive layer and a second semi-conductive layer are wrapped outside the first chloroprene rubber base inner sheath sequentially; three monitoring cable cores are sandwiched between the first semi-conductive layer and the second semi-conductive layer; and a chloroprene rubber base inner sheath and a mud-resisting thermosetting halogen-free polyolefin sheath layer are extruded outside the second semi-conductive layer sequentially. Due to the narrow using site of the cable of the shield machine and higher requirements on the bending performance of the cable, a soft conductor structure is adopted. Due to the adoption of a damp environment, tinned copper wires are selected. The mud-resisting high strength cable for the shield machine has a reasonably-selected material, a reasonable structure and long service life.
