In the small diameter pipe jacking method, a demand for a tunneling machine, with which long and curved tunnels can be constructed, has grown in recent years. It is necessary for constructing curved tunnels to control the direction of tunneling machine. This paper describes the design of tunneling machine for controlling its direction, whose direction control is achieved by both directional control mechanism and position measuring system. The tunneling machine designed based on this method has been used for constructing 50 meters long tunnels in silty loam deposits whose curvature radiuses were smaller than 200 meters. Experimental results show that this design method can realize long and curved tunnel in small diameter. (Author abstract)
