It is provided with a pneumatic pipe 33 having an upward nozzle 33a and a connecting pipe 33b branched from the pneumatic pipe and communicating with both hydraulic nozzles 32a, and excavated to the upper rear of the space 37. A discharge pipe 34 for discharging soil, rocks, etc. is disposed downward, and a lower rear part The suction part 36 is provided to assist the pressure raising action, and the cable guide pipe 35 having the cable entry hole 35a at the upper side is disposed between the rear of the body and the discharge pipe. 203a is a high pressure water connector, 400 is a traction wire, 101a is a compressed air connector, 102a is a cable guide part, 101b is a compressed air servant, C is a cable, and 302 is a flange portion hingedly coupled with a hydraulic cylinder.

이상과 같이 구성된 본 발명의 작용효과를 살펴보면, 도면 제1도에서와 같이, 포설선(100)의 전진으로 견인 와이어(400)에 연결된 잠수정(200)이 가이드판(201)에 의해 해저지면과 접촉되어 전방으로 전진되며, 이때 쟁기(205)가 줄터파기 및 장애물 제거작업을 행하게 된다.Looking at the effect of the present invention configured as described above, as shown in Figure 1, the submersible 200 connected to the traction wire 400 in the advance of the laying vessel 100 and the subsea surface by the guide plate 201 Contact is advanced to the front, at which time the plow 205 performs the digging and removing obstacles.

이와 동시에 유압모터(42)의 작동으로 스크류(4)가 회전되는데. 이때 개구부(38)로 노출된 스크류(4)의 외주연에 절삭 비트(41)(재질은 공업용 다이아몬드임)에 의하여 암반의 절삭이 용이하며 절삭된 암석의 부스러기 및 토사가 상승 운반된다.At the same time the screw (4) is rotated by the operation of the hydraulic motor (42). At this time, the cutting edge 41 (the material is an industrial diamond) is easily cut on the outer circumference of the screw 4 exposed through the opening 38, and the debris and soil of the cut rock are carried upwards.

이와 동시에 잠수정(200)에 부설된 수중펌프(203)의 작용으로 고압수가 연결관(203a)에 의해 수압관(32)으로 연결되어 분사노즐(32a)을 통해 분사되므로 스크류(4)의 세척과 함께 지반을 절삭하는 작업효율을 높여주게 한다.At the same time, the high pressure water is connected to the water pressure pipe 32 by the connection pipe 203a by the action of the submersible pump 203 installed in the submersible 200, and is sprayed through the injection nozzle 32a.

As it is sucked up and sucked up through the suction part 36, it joins with the cut soil rock by the screw and is discharged.

그리고 압축공기 연결관(101a)을 통해 유입된 압축공기는 연결파이프(33b)를 통해 분사노즐(32a)로 유입되어 고압수 분사를 가압시켜 보다 높은 고압수를 분사시킬 수 있도록 한다.In addition, the compressed air introduced through the compressed air connecting pipe 101a flows into the injection nozzle 32a through the connecting pipe 33b to pressurize the high-pressure water injection so as to inject a higher pressure water.

따라서, 굴삭기 몸체(3)에 의해 터파기가 시행되고, 포설선(100)의 케이블 드럼(102)으로부터 공급되는 케이블(C)이 구멍(35a)을 통하여 케이블 가이드관(35)에서 안내되어 터파기된 저부에 놓여짐과 동시에 배출관(34)으로 배출되는 토사암반 등으로 되메우기 작업이 이루어진다.Therefore, the excavation is carried out by the excavator body 3, and the cable C supplied from the cable drum 102 of the laying line 100 is guided through the hole 35a in the cable guide tube 35 and excavated. At the same time it is placed in the bottom and the backfill work is made to the soil deposits and the like discharged to the discharge pipe (34).

따라서 포설선(100)의 진행과 동시 케이블(C)의 매립이 연속적으로 진행되는 것이다.Therefore, the installation of the installation line 100 and the simultaneous filling of the cable (C) proceeds continuously.

이때 경질의 터파기 작업을 할 때는 도면 제3a도에서와 같이 몸체(3)의 폭보다 스크류(4)의 직경이 커야하며, 연질의 터파기 작업시에는(수압분사노즐(32a)에 의해 터파기가 시행되므로) 굴삭기 몸체(3)의 폭보다 스크류(4)의 직경이 작아도 된다.At this time, when the hard dig work, the diameter of the screw 4 should be larger than the width of the body 3, as shown in Figure 3a, and during the soft dig work (by the hydraulic spray nozzle 32a) The diameter of the screw 4 may be smaller than the width of the excavator body 3).

그리고, 본 장치는 유압실린더(204)의 작동으로 연결된 플랜지부(302)에 의해 잠수정(200)과 연결된 축(301)을 중심으로 일정각도내에서 굴삭면의 굴삭 각도 조정을 할 수 있으므로서 터파기의 심도 조정이 가능하며 수선 및 기타 교체 등을 잠수정으로부터 분리할 수도 있다.In addition, the present apparatus can adjust the excavation angle of the excavation surface within a predetermined angle about the axis 301 connected to the submersible 200 by the flange portion 302 connected by the operation of the hydraulic cylinder 204 Digging depth can be adjusted and repairs and other replacements can be separated from the submersible.
