    • A method of and a system for laying a pipe underground wherein a head attached to the leading end of the pipe to be laid underground is caused to move in vibratory movement while a propelling force is exerted on the rear end of the pipe to obtain penetration of the earth by the pipe. While the head is forced to move ahead by the propelling force exerted on the rear end of the pipe, the vibration of the head is measured. When the vibration drops in magnitude, the propelling force is decreased to reduce the speed at which the head is forced to move ahead; so as to cause restoration of the vibration to the original level, and when the vibration rises, the propelling force is increased to increase the speed at which the head is forced to move ahead.
    • 一种用于铺设地下管线的方法和系统,其中附接到地下管道的前端的头部在振动运动的同时在施加在管的后端的推进力上移动以获得穿透 地球由管道。 当通过施加在管的后端上的推进力迫使头部向前移动时,头部的振动被测量。 当振动大幅度下降时,推进力降低,以降低头部被迫向前移动的速度; 以使振动恢复到原来的水平,并且当振动升高时,推动力增加以增加头被迫向前移动的速度。
