본 고안은 지하철이나 도로공사에 터널을 시공할때, 암반이나 지반의 취약부분을 보강하기 위하여 사용되는 락 보울트(ROCK BOLT)를 단단하고 정확히 지지시켜 주게된 클립에 관한 것이다.The present invention relates to a clip that firmly and accurately supports a rock bolt used for reinforcing a weak part of a rock or ground when constructing a tunnel in a subway or road construction.
통상 터널공사시 암반이나 지반의 취약부분을 보강하기 위하여 그 부분에 구멍을 뚫어서 철근이나 강재등으로된 락 보울트를 삽입하고, 그 사이에 시멘트풀이나 몰탈 또는 콘크리트 등을 주입하여서 암반이나 지반자체의 전단 강도를 증가시켜 터널의 지반을 안정되게 하였었다. 그러나 상기 천공된 구멍에 삽입된 보울트가 보울트의 자체 무게로 인해 일측으로 기울어지기 때문에 구멍의 중앙에 고정시키기가 용이치 못하였으며, 구멍에 접착제를 충전시 접착제가 보울트의 주위에 균일하게 주입되지 않고 한쪽으로 치우쳐서 침하현상이 생기며 접착제가 유출되는 등 폐단이 있었다.In tunnel construction, in order to reinforce the weak part of rock or ground, insert a rock bolt made of reinforcing steel or steel by drilling a hole in the part, and injecting cement paste, mortar or concrete into the rock or ground itself. The shear strength was increased to stabilize the ground of the tunnel. However, since the bolt inserted into the perforated hole is inclined to one side due to the weight of the bolt, it is not easy to fix at the center of the hole, and when filling the adhesive into the hole, the adhesive is not uniformly injected around the bolt. There was a discontinuity such as sinking to one side and leakage of adhesive.
본 고안에서는 이러한 문제점을 감안하여서 일측에 개방된 관체의 내주벽에 다수의 압지돌조가 횡으로 돌출되고, 관체의 하부에는 하측으로 경사지게 벌어진 3개의 탄발지지편을 일체로 형성하여서된 클립을 제공하므로서 취약암반의 구멍에 삽입되는 보울트에 구멍의 중앙부에 단단히 고정시켜주게 된 것인 바, 이를 첨부된 도면에 따라 상세히 설명하면 다음과 같다.In the present invention, in view of the above problems, a plurality of blotting protrusions protrude horizontally on the inner circumferential wall of the tubular body opened at one side, and at the lower part of the tubular body, the three elastic support pieces which are inclined downwardly are integrally formed to provide a clip. It is to be firmly fixed to the center of the hole in the bolt inserted into the hole of the fragile rock, which will be described in detail according to the accompanying drawings.
클립(1)의 상부는 일측이 개방부(2')로 된 관체(2)이고, 관체(2)의 내주벽에는 압지돌조(3)가 횡으로 돌출되었으며, 관체(2)의 하부에는 외측으로 경사지게 벌어진 3개의 탄발지지편(4)을 일체로 된 구성이다.The upper part of the clip 1 is a tubular body 2 of which one side is an open part 2 ', and the crushing protrusion 3 is projected laterally on the inner circumferential wall of the tubular body 2, and the outer side of the lower part of the tubular body 2 is outside. It is a configuration in which three bullet support pieces 4 which are inclinedly inclined in one piece are integrated.
미설명부호 5는 보울트, 6은 취약암반, 7은 암반(6)에 천공된 구멍이다.Reference numeral 5 is a bolt, 6 is a weak rock, 7 is a hole drilled in the rock (6).
이와 같이된 본 고안의 작용효과를 보면 다음과 같다.Looking at the effect of the present invention as described above are as follows.
제3도는 천정부의 취약한 암반을 보강하게된 예로서 먼저 취약암반(6)에 구멍(7)을 천공하고 구멍(7)에 삽입할 보울트(5)에 본 고안의 클립(1)을 적당한 간격으로 끼우게 되는데 클립(1)은 탄성이 강한 강철판으로 되어 있어서 관체(2)를 약간 벌려서 보울트(5)에 끼우게 되면 관체(2)의 강한 탄성과 관체(2)의 내주벽에 횡으로 돌출된 압지돌조(3)에 의해 보울트(5)에 단단히 부착된다.3 is an example of reinforcing the fragile rock of the ceiling, and the clip 1 of the present invention is inserted into the bolt 5 to be drilled into the fragile rock 6 and inserted into the hole 7. If the clip (1) is made of a steel sheet having a strong elasticity, and the tubular body (2) is slightly opened and inserted into the bolt (5), the elasticity of the tubular body (2) and the inner circumferential wall of the tubular body (2) protrude horizontally. It is firmly attached to the bolt 5 by the blotting protrusion 3.
이와 같이 클립(1)을 부착시킨 보울트(5)를 상기의 구멍(7)에 끼우면 구멍(7)의 직경보다 더 넓게 벌어진 탄발지지편(4)이 구멍(7)의 내주벽에 압착되면서 삽입되어서 보울트(5)를 구멍(7)의 중앙부에 위치되도록 단단히 고정시켜 주게 되는 것이다.In this way, when the bolt 5 to which the clip 1 is attached is inserted into the hole 7, the elastic support piece 4 which is wider than the diameter of the hole 7 is pressed into the inner circumferential wall of the hole 7 and inserted. The bolt 5 is firmly fixed to be positioned at the center of the hole 7.
따라서, 상기와 같이 취약암반(6)이 천정부에 위치되더라도 구멍(7)에 삽입된 보울트(5)가 클립(1)에 단단히 지지되어서 낙하되지 않는다.Therefore, the bolt 5 inserted in the hole 7 is firmly supported by the clip 1 even if the weak rock 6 is located on the ceiling as described above, so that it does not fall.
다음 공정으로 구멍(7)에 시멘트몰탈이나 콘크리트등의 접착제를 주입기구를 사용하여 충전시키게 된다.In the next process, the hole 7 is filled with an adhesive such as cement mortar or concrete using an injection mechanism.
이때 접착제의 점도는 진한 반죽상태로서 충진완료후에는 구멍(7)의 입구를 막아서 접착제가 유출되는 것을 방지하게되며 클립(1)의 탄발지지편(4)도 낙하되는 접착제를 어느정도 저지시켜 주는 역할을 보조하게 되고 접착제가 굳어지면 보울트(5)와 취약암반(6)을 견고히 결속시켜서 취약암반(6)의 전단강도를 더욱 높여주게 되는 것이다.At this time, the viscosity of the adhesive is a thick kneading state after the filling is completed to block the entrance of the hole 7 to prevent the adhesive from leaking, and the elastic support piece (4) of the clip (1) also serves to block the falling adhesive to some extent When the adhesive is hardened and the adhesive is hardened to bind the bolt (5) and the vulnerable rock (6) is to increase the shear strength of the vulnerable rock (6) further.
