Abstract
Description
본 발명은 네일(nail)제거형 네일링(nailing)공법에 관한 것이다.The present invention relates to a nail removal method nailing (nailing) method.
일반적으로 네일링공법은 각종 굴착공사장에서 주변의 암반이나 토사등이 붕괴되는 것을 방지하기 위해서 시공되는 것으로서 터파기된 벽으로부터 하향경사진방향으로 드릴링을 하여 깊은 구멍을 천공하고, 네일주위에 호스를 고정하여 네일을 구멍속에 집어넣되, 네일이 구멍의 중앙부에 위치하도록 소정의 간격으로 스페이서를 네일에 결합시켜서 네일을 구멍속에 접어넣은 다음 상기 호스를 통하여 시멘트 페이스트, 레진 및 세민트몰탈등과 같은 그라우트(grout)를 공급함으로서 구멍자체를 네일을 심재로 하는 콘크리트파일로 만들어 굴착공사장주변의 지반이 붕괴되지 않도록 해주는 것이었다.In general, the nailing method is constructed to prevent the collapse of surrounding rock or soil at various excavation works. Drilling in a downward sloped direction from the ruptured wall to drill a deep hole, and attach a hose around the nail. The nail is inserted into the hole by fixing it, and the spacer is bonded to the nail at predetermined intervals so that the nail is located at the center of the hole, and the nail is folded into the hole. By supplying grout, the hole itself was made into a concrete pile with nail as a core so that the ground around the excavation site would not collapse.
그러나 이와같은 네일링공법은 구조물이 완공된 후에도 네일을 심재로 하는 콘크리트파일이 지하에 견고하게 잔존하는 것이어서 완성된 건물과 같은 구조물과 인접한 `곳에서 다른 구조물을 시공할때에 장애물이 되어서 다른 구조물의 공사에 많은 지장을 초래하는 등의 문제점이 있었다.However, the nailing method such as this is that the concrete piles with nail cores remain firmly in the basement even after the structure is completed, which becomes an obstacle when constructing other structures near the same structure as the completed building. There was a problem such as causing a lot of trouble in construction.
본 발명은 이와같은 종래 네일링공법의 제반문제점을 해결한 것인바, 본 발명의 목적은 네일링의 시공목적이 달성된 후에는 철강제인 네일을 제거하여 반복 사용할 수 있도록 하고 인접한 곳에서 다른 구조물을 시공할때에는 네일링에 의해서 지하에 잔존하는 콘크리트 파일을 용이하게 제거할 수 있도록 함으로서 다른 구조물공사에 지장을 초래하지 않는 네일링공법을 제공하는데 있다.The present invention solves all the problems of the conventional nailing method, the object of the present invention is to remove the nail made of steel after the purpose of the construction of the nailing can be used repeatedly and other structures in the vicinity In construction, it is possible to easily remove the concrete pile remaining in the basement by nailing to provide a nailing method that does not interfere with the construction of other structures.

본 발명은 도 1 ∼ 도 3에 예시한 바와같이 네일자체를 나선봉(1)으로 하고, 여러개의 소켓(2)과, 이 소켓(2)에 끼워맞춤되는 여러개의 중공관체(3)로 이루어진 네일링부재를 이용하여서 네일링하는 것이다.As shown in Figs. 1 to 3, the present invention uses a spiral bar 1 as a nail itself, and consists of a plurality of sockets 2 and a plurality of hollow tubular bodies 3 fitted to the sockets 2. Nailing using a nailing member.
소켓(2)의 내주면에는 나선봉(1)의 숫나선(4)과 맞물려지는 암나선(5)이 형성되어있고, 소켓(2)의 양측에는 상기 중공관체(3)의 단부가 끼워맞춤되는 단차부(6)가 형성되어있으며, 양단부의 플랜지(7),(7´)사이에는 돌출된 여러개의 리브(8)가 형성되어있고, 상기 플랜지(7),(7´)에는 그라우트 공급용 호스(9)가 끼워지는 여러개의 요홈(10)이 형성되어있다.The inner circumferential surface of the socket 2 is formed with a female spiral 5 engaged with the male spiral 4 of the spiral bar 1, and the ends of the hollow tube 3 are fitted to both sides of the socket 2. Steps 6 are formed, and protruding ribs 8 are formed between the flanges 7 and 7 'at both ends, and the flanges 7 and 7' are provided for grouting. A plurality of recesses 10 into which the hose 9 is fitted are formed.
도 3 에는 이와같은 네일링부재를 이용하여서 네일링하는 상태가 표현되어있다.3 shows a state of nailing using such a nailing member.
나선봉(1)에 여러개의 소켓(2)과 중공관체(3)를 교호로 결합하고, 소켓(2)의 플랜지(7),(7´)에 있는 요홈(10)에 그라우트용 호스(9)를 결합한 다음 드릴링된 구멍(20)속에 삽입하고, 그라우트용 호스(9)를 통해서 그라우트(12)를 공급하여 상기 소켓(2) 및 중공관체(3)들과 구멍(20)사이의 공간부(11)를 그라우트(12)로 채운다음 그라우트(12)를 굳혀서 네일링을 실시하는 것이다.Several sockets (2) and the hollow tube (3) are alternately coupled to the spiral rod (1), and the grout hose (9) is provided in the groove (10) in the flange (7), (7 ') of the socket (2). ) And then inserted into the drilled hole (20), the grout (12) is fed through the grout hose (9) to provide a space between the socket (2) and the hollow tube (3) and the hole (20) After filling 11 with grout 12, the grout 12 is hardened and nailing is performed.
이때 맨 아래쪽에 위치하는 소켓(2)에는 마개(13)를 결합시켜서 그라우트(12)가 소켓(2)내부로 유입되지 않도록 해주어야만 나선봉(1)을 소켓(2)들로부터 쉽게 제거할 수 있다. 따라서 소켓(2)의 한쪽 단차부(6)에는 도 1 에 잘 표현된 바와같이 암나선(14)을 형성하여 중공관체(3)를 끼워맞춤할 수 있도록 함과 아울러 숫나선(15)을 가진 마개(13)로 폐쇄시켜줄 수 있도록 해주는 것이 바람직하다.At this time, the stopper (13) is coupled to the bottom of the socket (13) so that the grout (12) does not flow into the socket (2), the spiral bar (1) can be easily removed from the socket (2) have. Accordingly, as shown in FIG. 1, one step 6 of the socket 2 forms a female spiral 14 so that the hollow tubular body 3 can be fitted and a male spiral 15 is provided. It is desirable to be able to close with a stopper (13).
이와같이 하여서 네일링을 하게되면 네일링의 근본목적이 달성된후 소켓(2)들과 나선결합되고 중공관체(3)들을 관통하는 나선봉(1)을 회전시켜서 쉽게 제거할 수 있다.In this way, the nailing can be easily removed by rotating the spiral bar (1) spirally coupled with the sockets (2) and through the hollow tube (3) after the basic purpose of the nailing is achieved.
본 발명의 예시도면에는 네일링되는 벽(16)에 시공되는 숏크리트(Shotcrete)와 와이어메쉬의 표현은 종래와 동일하므로 생략되어있다.In the exemplary drawings of the present invention, the expressions of shotcrete and wire mesh which are constructed on the nailed wall 16 are omitted since they are the same as in the related art.
본 발명에 있어서, 나선봉(1)에 소켓(2)들과 중공관체(3)들을 교호로 결합한 이유는 소켓(2)이 나선봉(1)처럼 길이가 긴 단일관체로 만들어주었을 때 네일링할 구멍(20)의 깊이에 따라서 현장에서 절단하여 사용해야만 하고, 제고하기도 어렵고, 비용이 많이들 뿐만아니라 나선봉(1)의 제거가 용이하지 않기 때문이다.In the present invention, the reason why the sockets 2 and the hollow tube 3 are alternately coupled to the spiral bar 1 is that the socket 2 is nailed when made into a single tube having a length as long as the spiral bar 1. According to the depth of the hole 20 to be cut and used in the field, it is difficult to improve, it is expensive, and the removal of the spiral bar 1 is not easy.
또 직경과 단면형상이 다른 상기 소켓(2)들과 중공관체(3)들은 도 4 와 도 5 에 예시한 바와같이 그라우트(12)와의 접촉면적을 증대시켜주어서 네일링을 매우 견고하게 할 수 있기 때문이다.In addition, the sockets 2 and the hollow tubes 3 having different diameters and cross-sectional shapes can increase the contact area with the grout 12 as illustrated in FIGS. 4 and 5, thereby making the nailing very hard. Because.
그리고 본 발명은 그라우트용 호스(9)가 소켓(2)자체에 끼워맞춤되는 형태로 고정되는 것이므로 별도의 고정수단을 사용하지 않고서도 그라우트 호스(9)를 간단하면서도 견고하게 고정시켜줄 수 있게 된다.In addition, since the grout hose 9 is fixed in a form that fits into the socket 2 itself, the grout hose 9 can be fixed simply and firmly without using a separate fixing means.
본 발명은 구조계산에 의해 설정되는 네일링할 구멍(20)의 깊이에 맞추어서 나선봉(1)에 여러개의 소켓(2)들과 중공관체(3)들을 교호로 결합하여 견고하게 네일링을 한다음 네일링의 목적이 달성된 후에도 나선봉(1)만을 손쉽게 제거하여 반복사용하고 인접한 장소에서 다른구조물을 시공할때에도 장애를 주지않는 장점이 있다.According to the present invention, a plurality of sockets (2) and hollow tubes (3) are alternately coupled to the spiral bar (1) in accordance with the depth of the hole to be nailed (20), which is set by the structural calculation, so that the nail is firmly nailed. Even after the purpose of the nailing is achieved, it is easy to remove only the spiral bar (1) repeatedly, and there is an advantage that does not interfere when constructing other structures in adjacent places.
