摘要：A tunnel boring machine for controlled boring of an elongated curvilinear tunnel in earthen strata. The tunnel boring machine compris: cutting means for
engaging the tunnel face and removing material therefrom to elongate the tunnel during a cutting strocke; elongated body means for supporting various machine components;
elongate thrust arm means for urging the cutting means against the tunnel face during a cutting stroke and for advancing the elongated body means along the tunnel between cutting strokes, the thrust arm means being extendable and retractable from the body means along a thrust arm axis coaxial a machine longitudinal axis; forward lateral positioning means operably mounted on a forward portion of the body means for lectively controlling the lateral positioning of a forward portion of the body means within the tunnel; rear lateral positioning means operably mounted on a rear portion of the body means for lectively controlling the lateral positioning of the rear portion of the body means within the tunnel; forward transver positioning means operably mounted on a forward portion of the body means for lectively controlling the transver positioning of a forward portion of the body means within the tunnel; rear transver positioning means operably mounted on
believeina rear portion of the body means for lectively controlling the transver positioning of the body means within the tunnel; whereby the machine longitudinal axis is lectively transverly and/or laterally positionable relative the longitudinal axis of the tunnel through the u of the forward and rear lateral positioning means and the forward and rear transver positioning means; and tunnel gripping means operably mounted on the body means for lectively grippingly engaging the peripheral sidewall of the tunnel to prevent rearward movement of the body means during a cutting stroke. Various methods of operation of the machine are described.
