본 고안은 토사 지역에서 직선으로 굴착하기 위한 굴착기의 굴착날 부분과 연약 지반의 토사층을 고결(固結)시키기 위하여 개량된 것이다.The present invention is improved to solidify the excavation blade portion of the excavator and the soil layer of the soft ground for excavation in a straight line in the soil area.

굴착판의 외주연으로부터 원통체를 연장하여 지중에서 굴착할 때 주위에 있는 토석의 교란으로 주변의 붕괴를 사전에 방지하고져 형성한 것이다.When the cylindrical body is extended from the outer periphery of the drilling plate and excavated in the ground, it is formed by preventing the collapse of the surroundings in advance by disturbing the surrounding soil.

종래의 굴착기는 제 1 도에서 보는 바와 같이 굴착판(2)의 전면이 연약 지반을 교란시켜 붕괴되며 니수가 교반되어 지각의 연약층을 형성케 한다.In the conventional excavator, as shown in FIG. 1, the front surface of the drilling plate 2 disturbs the soft ground and collapses, and the needle water is stirred to form the soft layer of the earth's crust.

이와 같은 결점을 해결하기 위하여 안출한 본 고안은 첨부 도면에 의하여 상세히 설명하면 다음과 같다.The present invention devised to solve this drawback is described in detail by the accompanying drawings as follows.

굴착기의 전방 원통관체(8)은 후방 원통체(9)의 앞에 일체로 연설된 연결 원통관체(9')에서 상하 좌우로 미동(微動)하기 위하여 연결되어 있고 전방 원통 관체(8)의 앞부분에 지지 돌축벽(8')을 용접하여 회전 원통체(10)를지지 베어링(11)(12)으로 회전 하도록 설치되어 있으며 회전 원통체(10)의 후단 내측에 설치된 모우터는 전방 원통관체(8)의 지지돌출벽(8')에 고정된 모우터의 힘으로 회전시키게 되어 있다. 또한 지지돌출벽(8')과 쎄그먼트(15) 사이에 유압시린다(16)을 설치하여 전반 원통체에서 후방으로 밀어내게 되어있다.The front cylindrical tube 8 of the excavator is connected to slide up and down and left and right from the connecting cylindrical tube 9 'which is integrally spoken in front of the rear cylinder 9 and is connected to the front of the front cylindrical tube 8. The motor is installed to rotate the rotating cylindrical body 10 by the support bearings 11 and 12 by welding the support protrusion wall 8 ', and the motor installed inside the rear end of the rotating cylindrical body 10 is the front cylindrical body 8. It is made to rotate by the force of the motor fixed to the support protrusion wall 8 '. In addition, a hydraulic cylinder (16) is provided between the support protrusion wall (8 ') and the segment (15) so as to be pushed back from the front cylindrical body.

이러한 종래의 기술에서 원통체(18)을 전방으로 연설하고 그 전단부에 굴착날(19)이 내외 둘레에 원형으로 붙어 있다.In this conventional technique, the cylindrical body 18 is forwarded and the excavation blade 19 is circularly attached to the inner and outer circumferences at the front end thereof.

니수 공급관(20)은 굴착용 토사를 원활히 배출하기 위하여 외주부(外周部)에 분할배치하여 되도록굴착기 외부 토사와 접촉을 방지하도록 되어 있다.The knee water supply pipe 20 is arranged in an outer circumferential part so as to smoothly discharge the excavated earth and sand to prevent contact with the external soil of the excavator.

씨멘트 몰탈 또는 기타의 지반 안정제는 전방 원통관체(8)의 둘레 수개소의 분출노즐(23)에 연설되어 절삭된 부분에 분출 경화층을 만든다.Cement mortar or other ground stabilizer is addressed to the ejection nozzles 23 at several circumferences of the front cylindrical tube 8 to form a spray hardened layer on the cut portion.

미 설명 부호 25, 25'는 굴착판(17)상에 붙어 있는 다수의 굴착날이며, 26, 26'는 니수와 혼합된 굴착물의 배출공이며, 27은 굴착물을 후방으로 이송하는 스크류 콘베어이다.Reference numerals 25, 25 'are a plurality of drilling blades attached to the drilling plate 17, 26, 26' is a discharge hole of the excavated material mixed with the needle water, 27 is a screw conveyor for transporting the excavation backwards .

이와같이 구성된 본 고안은 굴착판(17)의 외주연으로부터 길게 연장된 원통체(18)가 형성되어 있기 때문에 굴착 작업을 할때에 내부에서 전방으로 분출시키는 순수한 니수와 원통 관체(8) 외측으로 분출되는 경화제와 혼합 방지가 되어 공해 유발 요인을 제거하는 효과를 같게되며 또한 전단부 굴착날(19)는 토석의 교란을 적게 하고 굴착 하게되어 지반의 붕괴를 방지하여 종래의 굴착기의 결점을 제거하는 효과를 갖고 있다.The present invention configured as described above has a cylindrical body 18 extending from the outer periphery of the drilling plate 17, so that when the excavation work, the pure needle water and the cylindrical body 8 ejected to the front during the excavation work is ejected to the outside. The hardening agent is prevented from mixing with the same effect to remove the cause of pollution, and also the shear excavation blade (19) to reduce the disturbance of earth and excavation to prevent the collapse of the ground to remove the defects of the conventional excavator Have
