SYDNEY RAIL TUNNEL MACHINERY

This short article is concerned with details of the boring machinery that has been used in the twin rail tunnels between Edgecliff and Bondi junction near Sydney in Australia. It is the largest of its kind in Australia. Eight motors were used in conjunction with hydraulic pumps to exert a thrust of 180kn and a torque of 650 kilonewton metres on the cutting wheel, and gripping legs which stabilized the macine, and permitted transmission of the thrust and torque to the tunnel face. Details are given of the dust spoil extraction system and of the 1.67 km conveyor system that was used to remove the 152 tonnes of spoil per hour. The power supplies for the boring machine and tunnel services, the provisions that were made for eventual partial failure of the supply, and the method of connecting the power line to the machine are described. The article concludes with details of the organizations that took part in this 8 million dollar contract. It is accompanied by illustrations of the machine cutting head and of the motors and pumps.
