Description
본 발명은 기초공사용 강관말뚝에 관한 것으로서, 더욱 상세하게는 기초공사를 위하여 지중에 강관말뚝을 건입할 때 강관말뚝의 외주면과 천공갱의 내주면 사이에 틈이 발생되어 지하수가 강관말뚝의 하단부에 고이게 되고, 강관말뚝의 하단부에 고인 지하수로 인하여 지반이 연약해져 매입된 강관말뚝이 침하되는 것을 확실히 방지할 수 있는 구조를 갖도록 한 기초공사용 강관말뚝에 관한 것이다.The present invention relates to a steel pipe pile for basic construction, and more particularly, when a steel pipe pile is built into the ground for the foundation work, a gap is generated between the outer circumferential surface of the steel pipe pile and the inner circumferential surface of the drill pit, so that the groundwater is formed at the lower end of the steel pipe pile. And, it relates to a steel pipe pile for the basic public works to have a structure that can be prevented from sinking the steel pipe pile embedded by the ground due to groundwater accumulated in the lower end of the steel pipe pile.
일반적으로 구조물을 축조할 때 구조물의 부등침하와 허용치 이상의 침하를 방지하기 위한 기초공사는 필수적이다. 이러한 목적으로 시공되는 기초공사는 심도가 큰 기초와 심도가 낮은 기초로 분류된다. 이러한 기초공사는 강관말뚝을 지중에 관입시키는 강관말뚝의 관입시공법에 의해 시공되는데 이러한 관입시공법은 여러종류가 알려져 있으나 직항타공법이 널리 활용되고 있다.In general, when constructing a structure, it is essential to lay the foundation to prevent unequal settlement of the structure and settlement beyond the allowable value. Foundation works constructed for this purpose are classified into deep foundations and low depth foundations. The basic construction is constructed by the penetration method of the steel pipe piles that infiltrate the steel pipe piles into the ground. However, there are many known types of such penetration construction methods, but the non-stop drilling method is widely used.
본 명세서에서는 이러한 직항타공법에 의해 사용되는 강관말뚝에 대하여 기술된다는 것을 양지하기 바란다.It is to be noted that the present specification describes steel pipe piles used by such direct punching methods.
도 1은 종래의 기초공사용 강관말뚝의 구조를 도시한 단면도이며, 도 2는 종래의 기초공사용 강관말뚝을 사용하여 기초공사를 실시하였을 때를 예시하는 사용상태도이다.1 is a cross-sectional view showing the structure of a conventional steel pipe pile for basic construction, Figure 2 is a state diagram illustrating the use when performing the basic construction using a conventional steel pipe pile for basic construction.
도 1 및 도 2를 참조하면, 종래의 강관말뚝(a)은 소정직경과 길이를 갖는 강관으로서 하단부 외주면상에는 강관말뚝이 오거에 의해 지중에 관입될 때 강관말뚝의 하단부가 단단한 지반과 맞부딪쳐 강관말뚝의 하단부가 찌그러지는 것을 방지하기 위하여 강화링(b)이 조립되고 용접에 의해 고정부착되어 있다.1 and 2, the conventional steel pipe pile (a) is a steel pipe having a predetermined diameter and length, the lower end of the steel pipe pile hits the hard ground when the steel pipe pile is introduced into the ground by the auger on the lower peripheral surface Reinforcing ring (b) is assembled and fixed by welding in order to prevent the lower end of the warp.
그러나, 상기와 같이 구성을 갖는 종래의 강관말뚝(a)은 관입시공시 강관말뚝의 외주면에 고정부착된 상기 강화링(b)에 의해 강관말뚝(a)의 외주면과 천공갱(c)의 내주면 사이에 강화링(b)의 두께 만큼의 틈이 생기게 되어 강관말뚝(a)의 관입시공을 완료하였을 때 지중의 지하수가 상기 틈을 통하여 강관말뚝(a)의 하단부로 흘러내려 고이게되고, 이렇게 고인 지하수에 의해 강관말뚝(a)의 하단부와 맞닿은 단단한 지반이 지하수를 흡수하여 연약해지게 되어 관입시공이 완료된 강관말뚝(a)에 침하하게 됨으로 침하된 강관말뚝(a)을 재차 관입시공하여야 하기 때문에 공기가 길어지게 될 뿐만 아니라 이에 따른 공사비도 크게 증가하게 된다는 문제점이 잇었다.However, the conventional steel pipe pile (a) having the configuration as described above is the outer circumferential surface of the steel pipe pile (a) and the inner circumferential surface of the drill shaft (c) by the reinforcing ring (b) attached to the outer circumferential surface of the steel pipe pile at the time of penetration When the gap of the reinforcing ring (b) is formed between them, the groundwater in the ground flows down to the lower end of the steel pipe pile (a) through the gap when the construction of the steel pipe pile (a) is completed. Because the ground that is in contact with the lower part of the steel pipe pile (a) by the ground water absorbs the ground water and becomes weak, it sinks into the steel pipe pile (a) where the penetration construction is completed. Not only is the air longer, but there is a problem that the construction cost will increase accordingly.
본 발명은 상기와 같은 종래의 문제점을 고려하여 안출한 것으로서, 그 목적은 기초공사를 위하여 지중에 강관말뚝을 진입할 때 강관말뚝의 외주면과 천공갱의 내주면 사이에 틈이 발생되어 지하수가 강관말뚝의 하단부에 고이게 되고, 강관말뚝의 하단부에 고인 지하수로 인하여 지반이 연약해져 매입된 강관말뚝이 침하되는 것을 확실히 방지함으로써 공사기간을 단축함은 물론 공사비용을 크게 절감할 수 있는 기초공사용 강관말뚝을 제공하는 것이다.The present invention has been made in view of the conventional problems as described above, the purpose is that the gap between the outer peripheral surface of the steel pipe pile and the inner circumferential surface of the drill pit when entering the steel pipe pile in the ground for the foundation work, the groundwater steel pipe pile It is accumulated at the lower part of the pipe, and groundwater is accumulated at the lower part of the steel pipe pile so that the ground is weakened to prevent settlement of the steel pipe piles that are purchased, thereby shortening the construction period and providing steel pipe piles for basic construction that can greatly reduce the construction cost. It is.
