본 발명은 선단부에 차단판이 부착된 선굴착 매입 강관말뚝 및 이의 시공방법에 관한 것으로, 강관말뚝의 선단부 차단판을 설치하여 강관말뚝 길이 내부 전체에 불필요한 시멘트밀크 충전을 방지하도록 한 선단부에 차단판이 부착된 선굴착 매입 강관말뚝 및 이의 시공방법에 관한 것이다.The present invention relates to a pre-drilled embedded steel pipe pile with a blocking plate attached to the tip and a construction method thereof, wherein a blocking plate is attached to the tip to prevent unnecessary cement milk filling in the entire length of the steel pipe pile by installing a tip blocking plate of the steel pipe pile. Pre-drilled embedded steel pipe pile and its construction method.

일반적으로 선굴착 매입 말뚝에서 PC, PHC 등과 같은 콘크리트 말뚝은 선단부가 막혀있는 구조이나 강관말뚝은 강관의 얇은 두께에 의한 순단면적이 매우 적은 트인 구조이다.In general, concrete piles such as PC, PHC, etc., in the pre-drilled embedded pile have a structure in which the tip end is blocked, but the steel pipe pile has a very small net cross-sectional area due to the thin thickness of the steel pipe.

따라서, 상기한 강관말뚝을 토사층, 매립층, 풍화암층에 설치할 경우에는 지지층을 강관말뚝이 뚫고 들어가는 펀칭(punching)현상으로 침하가 발생하기 때문에 강관말뚝의 선단부 차단을 위하여 강관말뚝 선단부 직경(D)의 2∼4배까지 시멘트밀크를 주입하고 양생하여 선단부 차단을 확보하고 있다.Therefore, when the steel pipe pile is installed in the soil layer, the buried layer, and the weathered rock layer, since the settlement occurs due to the punching phenomenon in which the steel pipe pile penetrates, the steel pipe pile tip diameter (D) is 2 ~ Cement milk is injected and cured up to 4 times to secure the tip block.

그러나, 선단부 차단장치가 없는 강관말뚝의 경우에는 강관말뚝의 외벽과 굴착공벽의 틈새를 시멘트밀크로 충전하여야 주면마찰력이 확보되어 강관말뚝의 지지 기능이 가능하고, 이를 위하여는 굴착깊이 전체 길이에 시멘트밀크를 충전하여야만 강관말뚝의 외벽 틈새까지 완벽하게 충전되므로 선단부 구근에 이용되는 선단부 직경(D)의 2∼4배까지의 이외 부분은 재료 낭비적 요소가 크다.However, in the case of the steel pipe pile without the tip blocking device, the gap between the outer wall of the steel pipe pile and the excavation hole wall should be filled with cement milk to secure the frictional force and to support the steel pipe pile. Only when the milk is filled, it is completely filled to the gap of the outer wall of the steel pipe pile, so the parts other than up to 2 to 4 times the diameter (D) of the tip used for the tip bulb are large wasteful materials.

일부 현장에서 선단부 구근 형성부만 시멘트밀크를 주입 및 양생 후 차후에 강관 외벽과 토사공벽의 틈새에 별도로 호스를 이용하여 시멘트밀크를 주입하는 방법을 시도하고 있으나, 토사층, 매립층, 자갈층 등등은 공벽이 붕괴되어 틈새가 막히고 호스를 통한 시멘트밀크 주입이 곤란하거나 불량하여 설계마찰지지력 확보에 큰 문제를 일으키는 경우가 있으므로 특별한 주의가 요구되는 실정이다.In some sites, only the tip bulb forming part injects and cures cement milk, and later attempts to inject cement milk using a hose separately into the gap between the outer wall of the steel pipe and the earthwork wall, but the soil layer, the landfill layer, the gravel layer, etc. It is necessary to pay special attention because it may cause a big problem in securing design friction bearing capacity because of collapse or gap and clogging of cement milk through hose.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로서, 강관말뚝의 선단부 차단판을 설치하여 강관말뚝 길이 내부 전체에 불필요한 시멘트밀크 충전을 방지하여 경제적으로 큰 절감효과가 보장되며, 선굴착 토사공벽과 강관말뚝 외벽 사이 틈새가 충실하게 충전되어 설계예상지지력 확보가 확실하도록 한 선단부에 차단판이 부착된 선굴착 매입 강관말뚝 및 이의 시공방법을 제공하는데 그 목적이 있다.Therefore, the present invention was devised to solve the problems as described above, by installing a front end blocking plate of the steel pipe pile to prevent unnecessary cement milk filling the entire length of the steel pipe pile economical great savings effect is ensured, The purpose of the present invention is to provide a pre-drilled embedded steel pipe pile with a blocking plate attached to the distal end of the pre-earth excavated earthwork wall and the outer wall of the steel pipe pile to ensure the expected design support.

도 5a 내지 도 5d는 본 발명에 따른 선단부에 차단판이 부착된 선굴착 매입 강관말뚝을 시공하는 상태를 도시한 공정도이다.5A to 5D are process diagrams showing a state of constructing a pre-drilled embedded steel pipe pile having a blocking plate attached to a tip end according to the present invention.

이들 도면에 도시된 바와 같이, 본 발명에 따른 선단부에 차단판이 부착된 선굴착 매입 강관말뚝 시공방법은 선단부(12)에 차단판(20)이 부착된 선굴착 매입 강관말뚝(10)을 제작하는 단계; 상기 선단부(12)에 차단판(20)이 부착된 선굴착 매입 강관말뚝(10)을 시공할 대상지반을 일정한 깊이 및 직경으로 굴공하여 천공홀(H)을 형성하는 단계; 상기 천공홀(H)에 시멘트밀크, 모르타르, 콘크리트 중의 어느 하나로 이루어지는 혼합물(M)을 충전하는 단계; 상기 혼합물(M)이 충전된 천공홀(H)에 선단부(12)에 차단판(20)이 부착된 선굴착 매입 강관말뚝(10)을 압입하여 설치하는 단계로 이루어진다. As shown in these drawings, the pre-excavation embedded steel pipe pile construction method with a block plate attached to the tip portion in accordance with the present invention to produce a pre-rigged embedded steel pipe pile (10) with a block plate 20 attached to the tip portion (12) step; Forming a drilling hole (H) by drilling a target ground to be constructed with a pre-drilled embedded steel pipe pile (10) having a blocking plate (20) attached to the tip (12) to a predetermined depth and diameter; Filling the mixture hole M formed of any one of cement milk, mortar, and concrete into the drilling hole H; In the drilling hole (H) filled with the mixture (M) consists of the step of installing by pressing the pre-excavation embedded steel pipe pile 10 is attached to the front end portion 12 to the front end portion 12.

즉, 본 발명에 따른 선단부에 차단판이 부착된 선굴착 매입 강관말뚝 시공방법은 강관말뚝(10)의 선단부(12)에서 강관말뚝(10)의 직경(D)의 4D깊이 내부에 PVC 또는 철판으로 이루어진 차단판(20)을 설치하여 강관말뚝(10)의 상부 내주면에 시멘트밀크의 낭비를 사전에 제거하고, 강관말뚝(10)이 차단판(20)에 의해서 폐색됨으로 인하여 강관말뚝(10)의 부피가 확보되어서, 이것이 선단부(12)의 시멘트밀크를 압착하면서, 압착된 시멘트밀크는 강관말뚝(10)의 외주면과 천공홀(H) 공벽의 틈새를 충실하게 충전하여, 설계지지마찰력을 충분하게 확보함을 특징으로 한다.That is, the pre-drilled embedded steel pipe pile construction method with a block plate attached to the tip portion according to the present invention is a PVC or iron plate inside the 4D depth of the diameter (D) of the steel pipe pile 10 at the tip portion 12 of the steel pipe pile (10) By installing the blocking plate 20 made of steel pipe pile 10 to remove the waste of cement milk in advance, the steel pipe pile 10 is blocked by the blocking plate 20 of the steel pipe pile 10 As the volume is secured, this presses the cement milk of the tip portion 12, while the compressed cement milk faithfully fills the gap between the outer circumferential surface of the steel pipe pile 10 and the hole hole H wall, thereby sufficiently satisfying the design frictional force. Characterized in securing.

특히, 상기 천공홀(H)내에 충전된 시멘트밀크가 선단부(12)가 차단판(20)에 의해 폐색된 강관말뚝(10)을 하향으로 근입시킬 경우, 차단판(20)의 하부에 에어포켓이 발생되어, 그 부분에 시멘트밀크가 충분하게 충전되지 않아 폐색효과가 불량해 질 수 있으므로 차단판(20)과 시멘트밀크간에 있는 내부공기를 외부로 방출할 수 있도록 공기구멍(22)을 차단판(20)이나 강관말뚝(10)에 형성하여 에어포켓 현상을 원천적으로 방지하는 것이 바람직하다. In particular, when the cement milk filled in the drilling hole (H) is inclined downwardly the steel pipe pile 10 is closed by the blocking plate 20, the air pocket in the lower portion of the blocking plate 20 Is generated, the cement milk is not sufficiently filled in the part, so that the blocking effect may be poor, so that the air hole 22 is blocked to release the internal air between the blocking plate 20 and the cement milk to the outside. It is preferable to form the 20 or the steel pipe pile 10 to prevent the air pocket phenomenon at the source.
