| 摘要 |
A tubular elongate pole comprises a pole wall having a plurality of small diameter wires embedded in a polymer-containing matrix bonded to the wires to form an encapsulating shell of relatively low weight and which is substantially impermeable to aqueous corrosive liquids; the matrix has a density greater than that of concrete conventionally employed in reinforced concrete poles and yet the pole is considerably lighter in weight and indeed of a weight comparable to that of a wood pole.
