Description

소일네일링 공법이 적용된 흙막이 벽체{Retaining wall applied by method soil-nailing construction}Retaining wall applied by method soil-nailing construction}

본 발명은 소일네일링 공법이 적용된 흙막이 벽체에 관한 것이다.The present invention relates to a retaining wall to which the soil nailing method is applied.

소일네일링 공법은 흙막이 벽체 내부에서 발생하는 흙의 미끄러짐 혹은 분쇄를 방지하기 위해 흙 속에 철물(nail)을 박고 흙의 표면에는 쇼크리트를 타설하는 시공법으로, 철물로 보강된 부분 전체가 일체의 중력식 옹벽으로서 토압에 저항해 견고한 흙막이를 실현하게 된다. Soil nailing is a method of placing a nail in the soil to prevent the sliding or crushing of the soil generated inside the wall of the soil and placing shockcrete on the surface of the soil. As a retaining wall, it resists earth pressure and realizes a strong earth block.

흙막이 벽체의 깊이가 깊어지면 토압이 커지므로 벽체 자체의 무게를 키우기 위해 철물의 길이를 길게 해서 벽체의 두께를 두껍게 한다. 결국, 중력에 의한 저항력이 토압으로 발생하는 활동력보다 커서 흙막이 벽체가 외적 안정을 이룬다.As the depth of the wall becomes deeper, the earth pressure increases, so in order to increase the weight of the wall itself, the length of the hardware is increased to make the wall thicker. As a result, the earthquake wall is externally stable because the resistance by gravity is greater than the force generated by earth pressure.

한편, 쇼크리트가 타설된 흙막이 전면은 안정되고 견고한 외관미를 확보하기 위해 블록이 축조될 수 있다. 그런데, 이러한 블록은 흙막이 벽체의 굴곡진 표면과는 무관하게 정축조 또는 후퇴축조가 획일적으로 이루어지므로, 블록을 이용한 흙막이 공법을 적용하기엔 부적절한 협소한 장소나, 흙막이 전면이 갖는 고유한 굴곡면을 유지해야 하는 장소에서는 블록을 이용한 소일네일링 공법 적용에 어려움이 있었다.On the other hand, the front surface of the earthenware on which the shock concrete is poured, the block may be constructed to secure a stable and solid appearance. However, since these blocks are made of uniform or receding structures uniformly regardless of the curved surface of the retaining wall, the block maintains a unique curved surface or a unique curved surface of the retaining surface. In places where it was necessary, there was a difficulty in applying the soil nailing method using blocks.

이에 본 발명은 상기와 같은 문제를 해소하기 위해 안출된 것으로, 소일네일링 공법을 이용한 흙막이 공사에서 안정된 흙막이 벽체를 이루기 위해 흙막이 전면을 덮어 마감하는 블록을 장소의 구해 없이 적용해 축조할 수 있고, 굴곡진 전면의 모습을 그대로 드러나도록 해서 자연스런 외관을 갖출 수 있도록 하는 소일네일링 공법이 적용된 흙막이 벽체의 제공을 기술적 과제로 한다.Therefore, the present invention has been devised to solve the above problems, it is possible to build by applying the block covering the entire surface of the earth film to achieve a stable earth wall in the earthwork construction using the soil nailing method without having to save the place, The technical task is to provide a soil wall that is applied with a soil nailing method that allows the curved front surface to be exposed as it is to have a natural appearance.

본 발명에 따른 블록(1)의 실시예인 제1,2블록(10, 20)은 상하로 조적되는 다른 블록과의 연결을 위해 돌기(14, 24)와 인입홈(15, 25)을 형성한다. 돌기(14, 24)는 인입홈(15, 25)과 맞물려서 상하로 조적된 블록들 간의 결속을 도모하며, 이 를 위한 돌기(14, 24)와 인입홈(15, 25)은 제1,2블록(10, 20)의 상면 및 저면에 각각 배치된다. 즉, 돌기(14, 24)가 제1,2블록(10, 20)의 상면에 배치되면 이에 상응해서 인입홈(15, 25)은 저면에 배치되고, 그 반대로 돌기가 제1,2블록(10, 20)의 저면에 배치되면 이에 상응해서 인입홈은 상면에 배치되는 것이다.The first and second blocks 10 and 20, which are embodiments of the block 1 according to the present invention, form protrusions 14 and 24 and recessed grooves 15 and 25 for connection with other blocks that are stacked up and down. . The protrusions 14 and 24 are engaged with the inlet grooves 15 and 25 to promote binding between the blocks that are assembled up and down, and the protrusions 14 and 24 and the inlet grooves 15 and 25 for the first and second ends thereof. The upper and lower surfaces of the blocks 10 and 20 are respectively disposed. That is, when the protrusions 14 and 24 are disposed on the upper surfaces of the first and second blocks 10 and 20, the recess grooves 15 and 25 are correspondingly disposed on the bottom surface, and conversely, the protrusions 14 and 24 are disposed on the first and second blocks 10 and 20. 10, 20) is arranged on the bottom surface corresponding to the inlet groove is arranged on the top surface.

한편, 본 발명에 따른 제1,2블록(10, 20)은 토사면(W)의 굴곡을 따라 배치되므로, 상하로 조적된 블록들 간의 전면 방향이 다를 수 있다. 따라서, 상하로 조적된 블록(1)이 각각 다양한 방향으로 배치될 수 있도록, 인입홈(15, 25)에 삽입된 돌기(14, 24)는 회전가능하게 고정되는 것이 바람직하고, 이를 위해 상기 돌기(14, 24)는 원기둥 형상을 이루어야 할 것이다.On the other hand, since the first and second blocks 10 and 20 according to the present invention are disposed along the curvature of the soil surface W, the front direction between the blocks stacked up and down may be different. Therefore, the protrusions 14 and 24 inserted into the inlet grooves 15 and 25 are preferably rotatably fixed so that the blocks 1 stacked up and down may be arranged in various directions, respectively. (14, 24) should be cylindrical.

도 10은 본 발명에 따른 블록의 또 다른 실시예를 도시한 사시도이고, 도 11은 도 10에 도시한 블록의 연결모습을 도시한 평면도인 바, 이를 참조해 설명한다.10 is a perspective view showing another embodiment of a block according to the present invention, Figure 11 is a plan view showing a connection of the block shown in Figure 10, it will be described with reference to this.

본 발명에 따른 블록(1)의 실시예인 제1,2블록(10, 20)은 이웃하는 블록과의 절곡된 연결상태를 안정적으로 유지하기 위해, 지지편(90)을 박아 끼울 수 있는 반 호 형상의 지지홈(16, 26)을 형성한다. 이 지지홈(16, 26)은 회동홈(13, 23)을 중심으로 하는 반 호 형상으로, 서로 연결되는 블록(1)에 형성되는 지지홈(16, 26)은 회동홈(13, 23)을 중심으로 동일한 위치에 형성 배치된다.The first and second blocks 10 and 20, which are embodiments of the block 1 according to the present invention, can be inserted into the support piece 90 so as to stably maintain a bent connection state with a neighboring block. The support grooves 16 and 26 are formed. The support grooves 16 and 26 have a half arc shape centering on the rotation grooves 13 and 23, and the support grooves 16 and 26 formed in the blocks 1 connected to each other are the rotation grooves 13 and 23. It is formed and formed in the same position around.

따라서, 도 11에 도시한 바와 같이, 블록의 절곡 정도에 따라 상호 교차되는 지지홈(16, 26)의 관통범위가 달라지고, 그 관통범위에 맞는 크기의 지지편(90)을 교차된 지지홈(16, 26)에 받아 넣어서, 일방향으로 절곡된 이웃하는 블록들을 현상 태가 유지되도록 안정되게 지지한다. 물론, 타방향으로 절곡되는 것은 지지편(90)에 의해 저지되지 못할 수 있지만, 토사면(W)의 굴곡을 따라 배치되는 제1,2블록(10, 20)은 토사면(W)의 토압이 전방을 향하면서 일방향으로 외력을 가하므로, 제1,2블록(10, 20) 간의 연결부는 일방향으로만 힘을 받게 된다.Therefore, as illustrated in FIG. 11, the penetration range of the support grooves 16 and 26 that cross each other varies depending on the degree of bending of the block, and the support groove that crosses the support piece 90 having a size corresponding to the penetration range thereof. Received at (16, 26), the neighboring blocks bent in one direction are stably supported to maintain the present state. Of course, bending in the other direction may not be prevented by the support piece 90, but the first and second blocks 10 and 20 arranged along the curvature of the soil surface W may have the earth pressure of the soil surface W. Since the external force is applied in one direction while facing the front, the connection portion between the first and second blocks 10 and 20 is forced in only one direction.

참고로, 이웃하는 블록이 일렬로 배치될 경우엔, 반 호 형상의 지지홈(16, 26) 전체가 교차하므로, 180도의 원호를 단면으로 갖는 지지편이 끼워질 것이고, 도 11(a)에서 도 11(b)로 갈수록 이웃하는 블록의 절곡된 각이 커지면서 지지편(90, 90')의 원호는 짧아질 것이다.For reference, when the neighboring blocks are arranged in a line, since the entire half arc-shaped support grooves 16 and 26 intersect, a support piece having a circular arc of 180 degrees in cross section will be inserted, and in FIG. The arc of the support pieces 90, 90 'will be shorter as the bent angle of the neighboring blocks increases toward 11 (b).

한편, 본 실시예에서는 지지홈(16, 26)의 형상을 반 호로 하였지만, 호의 길이를 조정할 수도 있음은 물론이다.On the other hand, in the present embodiment, the shape of the support grooves 16, 26 is half arc, but of course the length of the arc can be adjusted.
