이와 같이 구성된 본 발명에 따른 지하굴착을 위한 그라우팅 장치의 동작을 설명하면 다음과 같다.Referring to the operation of the grouting device for underground excavation according to the present invention configured as described above are as follows.

먼저, 트랙터(12)를 천공된 구멍(예를들어, 터널(90) 등)의 전방에 위치시킨다.First, the tractor 12 is positioned in front of a drilled hole (eg, tunnel 90, etc.).

그리고, 트랙터(12)의 사방에 설치된 지지다리(10)를 적당한 위치에 위치시킴과 아울러 제2유압실린더(20)를 이용하여 제3지지대(24)와 연결된 착지판(26)을 땅 바닥에 위치시킨다.Then, the support legs 10 installed on all sides of the tractor 12 are positioned at appropriate positions, and the landing plate 26 connected to the third support 24 is connected to the ground using the second hydraulic cylinder 20. Position it.

그런후에, 제1유압실린더(18)를 이용하여 제1지지대(14)와 연결된 하부프레임(16)을 상 또는 하로 이동시킨다.Thereafter, the first hydraulic cylinder 18 is used to move the lower frame 16 connected with the first support 14 up or down.

또한, 시멘트 슬러지그라우팅부(32)의 일측에 설치된 그라우팅로드관(28)을 천공된 구멍으로 위치시킴과 아울러 그라우팅로드관(28)을 천공된 구멍에 밀어 넣는다.In addition, the grouting rod tube 28 installed on one side of the cement sludge grouting portion 32 is positioned as a perforated hole and the grouting rod tube 28 is pushed into the perforated hole.

여기서, 상기 그라우팅로드관(28)의 내부에는 시멘트 슬러지를 그라우팅시키는 그라우팅관(30)이 설치되어 있다.Here, a grouting pipe 30 for grouting cement sludge is installed in the grouting rod pipe 28.

그런후에, 상기 그라우팅로드관(28)의 내부로 제1 및 제2고무패킹(38)(40)이 설치된 그라우팅관(30)을 일측 끝단부까지 밀어 넣는다.Then, the grouting tube 30, the first and second rubber packing 38, 40 is installed into the grouting rod tube 28 is pushed to one end.

그리고, 시멘트 슬러지그라우팅부(32)는 그라우팅로드관(28)의 내부에 형성된 그라우팅관(30)으로 시멘트 슬러지를 그라우팅한다.The cement sludge grouting part 32 grouts the cement sludge with the grouting pipe 30 formed in the grouting rod pipe 28.

이때, 그라우팅관(30)의 분출공(36)을 통해 시멘트 슬러지가그라우팅로드관(28)의 내부로 토출된다. 또한, 그라우팅로드관(28)의 내부로 분출된 시멘트 슬러지는 다시 상기 그라우팅로드관(28)의 분출공(34)을 통해 천공된 구멍으로 흘러간다.At this time, the cement sludge is discharged into the grouting rod tube 28 through the ejection hole 36 of the grouting tube 30. In addition, the cement sludge ejected into the grouting rod tube 28 flows back into the punched hole through the ejection hole 34 of the grouting rod tube 28.

그런후에, 도 4에 도시된 바와 같이, 그라우팅로드관(28)의 내부에 형성된 그라우팅관(30)을 일정길이 앞으로 잡아 당긴다.Then, as shown in FIG. 4, the grouting tube 30 formed inside the grouting rod tube 28 is pulled forward by a predetermined length.

이때, 그라우팅로드관(28)의 내부로 분출된 시멘트 슬러지는 상기 그라우팅로드관(28)의 분출공(34)을 통해 천공된 구멍으로 흘러간다.At this time, the cement sludge ejected into the grouting rod pipe 28 flows into the drilled hole through the ejection hole 34 of the grouting rod pipe 28.

따라서, 천공된 구멍으로 흘러간 시멘트 슬러지는 토사와 견고하게 결합된다.Thus, the cement sludge flowing into the drilled hole is firmly combined with the soil.

이상에서 상술한 바와 같이 본 발명에 따른 지하굴착을 위한 강관 보강공의 그라우팅 장치는 터널의 상층부위의 연약한 지반에 시멘트 슬러지를 견고하게 그라우팅할 수 있는 효과가 있다.As described above, the grouting device of the steel pipe reinforcing hole for underground excavation according to the present invention has the effect of firmly grouting the cement sludge on the soft ground of the upper layer of the tunnel.

따라서, 연약한 지반을 견고하게 유지할 수 있음으로써 터널을 오래동안 사용할 수 있는 효과가 있다.Therefore, it is possible to use the tunnel for a long time by maintaining the soft ground firmly.
