Description
본 고안은 굴착공사용 지반 지지체에 관한 것으로서, 특히 건축이나 토목공사에서 지반이나 암반 등을 견고하게 지탱하기 위한 네일링 공사에 사용되는 굴착공사용 지반 지지체에 관한 것이다.The present invention relates to an excavated ground support, and more particularly, to an excavated ground support used for nailing construction for firmly supporting the ground or rock in construction or civil engineering.
일반적으로 지하 굴착공사, 터널공사, 사면공사, 옹벽공사 등의 각종 굴착공사를 할 때에는 주위의 암반, 토사, 지반 등이 무너지는 것을 방지하기 위하여 주위의 암반이나 지반 등에 네일을 박는 네일링 공사를 행한다.In general, in the excavation work such as underground excavation, tunnel work, slope work, retaining wall work, nailing work is applied to the surrounding rock or ground in order to prevent the surrounding rock, soil, and ground from collapsing. Do it.
이 네일링 공사는 먼저 암반이나 지반 등에 천공홀을 형성한 후, 이 천공홀에 지반 지지체, 네일 등을 삽입한 후 천공홀 속으로 응고되는 충진제를 충진시켜 암반이나 지반 등이 붕괴되는 것을 막는다.The nailing work first forms a drill hole in a rock or ground, and then inserts a ground support, a nail, etc. into the drill hole, and then fills a filler solidified into the drill hole to prevent the rock or ground from collapse.
여기서, 암반이나 지반에 형성되는 천공홀은 지반 지지체의 형태대로 천공되지 않기 때문에 지반 지지체가 천공홀에 삽입 시 암반이나 지반의 연약한 부분을 밀면서 삽입되게 된다. Here, since the perforation hole formed in the rock or ground is not perforated in the form of the ground support, the ground support is inserted while pushing the fragile portion of the rock or the ground when the ground support is inserted into the perforation hole.
그런데, 천공홀에 삽입되는 종래의 지반 지지체는 원기둥 형상으로 중심부에 네일이 삽입되는 중심홀만이 형성되어 있기 때문에 천공홀 삽입 시, 천공홀 내부에 존재하는 공기를 외부로 배출하지 못하게 된다. 그러면, 천공홀 내에는 지반 지지체 등과 공기가 공존하게 되어, 네일링 공사가 완료되어 지반이 다져지더라도 내부 밀도가 낮아 쉽게 붕괴되는 문제점이 있다.However, since the conventional ground support inserted into the drilling hole has only a center hole in which a nail is inserted into the center in a cylindrical shape, air existing in the drilling hole may not be discharged to the outside when the drilling hole is inserted. Then, the ground support and the air coexist in the drilling hole, even if the nailing work is completed, the ground is compacted, there is a problem that the internal density is low easily collapsed.
본 고안은 상기의 문제점을 해결하기 위하여 창안된 것으로서, 네일링 공사 중 천공홀에 존재하는 공기를 외부로 배출하여 지반이나 암반 등을 견고하게 지지할 수 있는 개선된 지반 지지체를 제공하는데 그 목적이 있다.The present invention was devised to solve the above problems, and to provide an improved ground support that can firmly support the ground or rock by discharging the air present in the drilling hole to the outside during the nailing construction have.
상기의 목적을 달성하기 위한 본 고안의 굴착공사용 지반 지지체는, 지반의 천공홀에 삽입되어 상기 지반을 지지하며, 외면에 유착로가 형성되도록 다수의 유착돌기가 소정 간격으로 돌출되고, 상기 천공홀에 삽입되는 방향으로 내부를 관통하는 다수의 에어토출공이 형성된다.Excavation ground support of the present invention for achieving the above object is inserted into the boring hole of the ground to support the ground, a plurality of coalescing projections protrude at predetermined intervals so that the coalescence path is formed on the outer surface, the drilling hole A plurality of air discharge holes penetrating the inside in the direction to be inserted into is formed.
여기서, 상기 지반 지지체는 다각형 기둥 형상인 것이 바람직하다.Here, the ground support is preferably a polygonal columnar shape.
또한, 상기 유착로는 상기 천공홀에 삽입되는 방향과 교차되는 방향의 나선 형상인 것이 바람직하다.In addition, it is preferable that the coalescence path has a spiral shape in a direction intersecting with a direction inserted into the drilling hole.
또한, 상기 유착로는 상기 천공홀에 삽입되는 방향과 교차되는 방향으로 나란하게 배열되는 것이 바람직하다.In addition, the coalescence path is preferably arranged side by side in the direction crossing with the direction to be inserted into the drilling hole.
이하 첨부된 도면을 참조하면서 본 고안의 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안의 네일링 장치를 나타낸 단면도이고, 도 2는 도 1의 지반 지지체의 일 실시예를 나타낸 사시도이다.1 is a cross-sectional view showing a nailing device of the present invention, Figure 2 is a perspective view showing an embodiment of the ground support of FIG.
도면을 참조하면, 상기 네일링 장치는 지반 지지체(10)와, 이 지반 지지체(10)의 중공(11)에 삽입된 네일(20)을 지반이나 암반(40) 등에 미리 천공한 천공홀(30)에 삽입한 후 충진제 등으로 천공홀(30)을 충진하여 지반이나 암반(40) 등의 붕괴를 막는다.Referring to the drawings, the nailing apparatus includes a ground support 10 and a drilled hole 30 in which the nail 20 inserted into the hollow 11 of the ground support 10 is previously bored to the ground or rock 40. ) And then filling the perforation hole 30 with a filler to prevent the collapse of the ground or rock 40 and the like.
여기서, 지반 지지체(10)는 천공홀(30)에 삽입되어 천공홀(30)의 내주면을 지지하는 것으로, 네일(20)이 삽입되도록 천공홀(30)이 삽입된 방향으로 중공(11)이 형성된다. 그리고 중공(11)이 형성된 방향과 평행의 방향으로 다수의 에어(air) 토출공(12)이 형성된다. Here, the ground support 10 is inserted into the drilling hole 30 to support the inner circumferential surface of the drilling hole 30, the hollow 11 in the direction in which the drilling hole 30 is inserted so that the nail 20 is inserted Is formed. In addition, a plurality of air discharge holes 12 are formed in a direction parallel to the direction in which the hollow 11 is formed.
이 에어 토출공(12)은 천공홀(30) 내로 지반 지지체(10)가 삽입될 때, 천공홀(30) 내에 존재하는 공기를 외부로 배출하여 일련의 과정에 의한 네일링 공사가 완료된 후 천공홀(30) 내부의 밀도를 높이기 위한 것이다.When the ground support 10 is inserted into the drilling hole 30, the air discharge hole 12 discharges the air existing in the drilling hole 30 to the outside and then drills after nailing work is completed by a series of processes. This is to increase the density inside the hole 30.
즉, 네일링 공사가 완료된 후에 천공홀(30) 내부에 공기가 잔존하게 되면 공극이 생겨 지반이나 암반(40) 등을 견고하게 지지하지 못하게 되므로, 천공홀(30) 내부의 공기를 외부로 배출하여 지반이나 암반(40) 등을 견고하게 지지하기 위한 것이다.In other words, if the air remains inside the drilling hole 30 after the nailing work is completed, voids are generated so that the ground or rock 40 cannot be firmly supported, and the air inside the drilling hole 30 is discharged to the outside. It is intended to firmly support the ground or rock 40 and the like.
그리고 지반 지지체(10)는 다각형(원형 포함) 기둥 형상으로, 외면에는 유착로(14)를 형성하기 위한 다수의 유착돌기(13)가 소정 간격으로 돌출된다. In addition, the ground support 10 has a polygonal (including circular) columnar shape, and a plurality of coalescing protrusions 13 for forming the coalescence path 14 protrude at predetermined intervals on an outer surface thereof.
여기서, 유착로(14)는 천공홀(30)에 삽입되는 방향과 교차되는 방향의 나선 형상으로 형성될 수 있고, 또한 도 3과 같이 천공홀(30)에 삽입되는 방향과 교차되는 방향으로 나란하게 형성될 수 있다.Here, the coalescence passage 14 may be formed in a spiral shape in a direction intersecting the direction inserted into the drilling hole 30, and also parallel to the direction intersecting the direction inserted into the drilling hole 30 as shown in FIG. Can be formed.
이 유착로(14)는 지반이나 암반(40) 등의 토사와 접촉 면적을 넓혀 지반이나 암반(40) 등을 견고하게 지지하기 위한 것이다.The coalescence path 14 is intended to firmly support the ground, the rock 40 and the like by expanding the contact area with the soil and the soil such as the ground and the rock 40.
즉, 암수 형태의 유착로(14)와 유착돌기(13)가 교대로 형성되어 홈 형상의 유착로(14)에 지반이나 암반(40) 등의 토사가 수용되고, 이 수용된 토사는 돌출된 유착돌기(13)에 의하여 이탈이 방지되므로 밋밋한 면을 가진 종래의 지반 지지체보다 더 견고하게 지반이나 암반 등을 지지하게 된다.That is, the male and female coalescing path 14 and the coalescing protrusion 13 are alternately formed, so that soils such as ground or rock 40 are accommodated in the groove-shaped coalescing path 14, and the accommodated soils are projected coalescing. Since the protrusion is prevented by the protrusion 13, the ground or the rock is supported more firmly than the conventional ground support having a flat surface.
이와 같은 구조의 지반 지지체(10)는 천공홀(30) 삽입 시, 지반 지지체(10)에 형성된 다수의 에어 토출공(12)에 의하여 천공홀(30) 내부에 존재하는 공기를 외부로 배출하여 네일링 공사 완료 후 천공홀(30)의 밀도를 높여 지반이나 암반(40) 등을 견고하게 지지할 수 있다. 그리고 지반 지지체(10) 외면에 형성된 유착로(14)와 유착돌기(13)에 의하여 지반이나 암반(40) 등의 내주면과 더 넓은 면적으로 접촉하여 견고하게 지지하게 된다.The ground support 10 having such a structure discharges air existing in the drilling hole 30 to the outside by a plurality of air discharge holes 12 formed in the ground support 10 when the drilling hole 30 is inserted. After the completion of the nailing construction to increase the density of the drilling hole 30 can be firmly supported on the ground or rock (40). And by the coalescence path 14 and the coalescence projection 13 formed on the outer surface of the ground support 10 in contact with the inner circumferential surface of the ground or rock 40, such as a wider area to be firmly supported.
상술한 바와 같이 본 고안의 굴착공사용 지반 지지체에 의하면, 지반 지지체의 천공홀 삽입 시 천공홀 내부에 존재하는 공기를 지반 지지체에 형성된 에어토출공을 통해 외부로 배출하여 네일링 공사 완료 시 견고하게 지반이나 암반 등을 지지할 수 있는 효과를 제공한다.As described above, according to the ground support for the excavated construction of the present invention, when the drilling hole is inserted into the ground support, the air existing inside the drilling hole is discharged to the outside through the air discharge hole formed in the ground support, so that the ground is firmly completed when the nailing work is completed. Provides the effect of supporting rock or rock.
