Summary:The present invention relates to underground excavation equipment comprising: an excavation machine for excavating the ground by receiving propulsion from a propulsion device; a propulsion pipe disposed on the rear of the excavation machine; a lubricant discharge means having a plurality of lubricant discharge ports formed along the outer circumference of the propulsion pipe; a clogging prevention means for each outlet of the lubricant discharge means; and a guard means for protecting the clogging prevention means from excavation debris generated by the excavation machine. The lubricant discharge ports can be reliably prevented from being occluded by stones, soil, or the like, and thus a lubricant is discharged smoothly, so that an excavation operation can be smoothly carried out with reduced frictional resistance to the ground (excavation hole), and working speed (propulsion speed) can be prevented from being lowered due to the uneven discharge of a lubricant. 본 발명은 추진장치로부터 추진력을 제공받아 지반을 굴착하는 굴착머신; 상기 굴착머신의 후방 측에 배치되는 추진관; 상기 추진관의 외주연을 따라 형성되는 다수의 활제 토출구를 갖는 활제토출수단; 상기 활제토출수단의 각 토출구에 대한 막힘방지수단; 및 상기 굴착머신에 의해 발생한 굴착 잔해물로부터 상기 막힘방지수단을 보호하기 위한 가드수단;을 포함함으로써, 활제 토출구가 돌, 토사 등에 의하여 폐색되는 것을 확실하게 방지할 수 있고, 이로써 활제가 원활하게 토출되므로 굴착 작업을 지반(굴착공)과의 마찰 저항이 감소된 상태로 원활히 진행할 수 있으며, 활제의 비(非)원활한 토출로 인하여 작업 속도(추진 속도)가 저하되는 현상을 방지할 수 있는 지중 굴착 장비에 관한 것이다.
