Unusual tunneling machine cuts and lines storm sewer
New device, which is called Teredo, was built by construction firm in Houston, Tex, for own purposes, and also doubles as slipform for concrete lining; cutters that bite into tunnel face are mounted on rotating arm; spoil is removed by pumped-in city water; device is built within 29 ft long, 11 1/2 ft diam steel shell of three sections; end section is outer shell for concreting of tunnel lining; concrete is poured in from street through manholes; 30% saving by new device.
