일반적으로 토목, 건축구조물에서 지반의 침하를 막기위해 기초로 말뚝기초를 많이 사용하고 있으며, 말뚝기초는 크게 기성말뚝(강관말뚝, 콘크리트말뚝 등)을 현장에서 항타장비를 이용하여 지중에 거치시키는 항타말뚝과, 지반을 미리 굴착하고 그 속에 철근망을 삽입한후 콘크리트를 타설하는 현장타설말뚝으로 구별된다.In general, pile foundations are frequently used as foundations to prevent ground subsidence in civil engineering and building structures, and pile foundations are largely used to mount ready-made piles (steel pipe piles, concrete piles, etc.) on the ground using driving equipment on site. It is divided into a pile and a site-placement pile in which concrete is excavated after inserting a reinforcing bar into the ground in advance.
항타말뚝과 현장타설말뚝은 각각 장 ·단점이 있으나 근래에는 구조물의 대형화에 따른 상재하중의 증가와 시공깊이의 제한과 특히 소음 및 진동문제로 인해 도심지 부근에서는 민원이 급증하기때문에 최근에는 현장타설말뚝이 선호되고 있는 실정이다.Driving piles and cast-in-place piles have advantages and disadvantages, but in recent years, since the civil complaints increase in urban areas due to the increase in load and the depth of construction due to the large size of the structure, and especially the noise and vibration problems, the cast-in-place piles This is the preferred situation.
그러나 기존의 현장타설말뚝은 소음이 적고, 현장에서 요구하는 소정의 깊이까지 관입시킬 수 있는 이점이 있으나, 압축 및 전단에 대한 보강재로서 적용하는 철근망의 조립시 공간 확보 및 장비의 수급으로 인한 문제, 이동 및 시공시 발생되는 복잡한 공정 등으로 인해 인력, 시간 및 공사비간 많이 소요되어 현실적으로 그 적용에 많은 어려움이 있을뿐만아니라 최대골재의 크기보다 큰 구멍을 적용함으로써 콘크리트 타설시 발생할 수 있는 가장 치명적인 문제점인 재료의 분리가발생할 뿐만아니라 시공의 편의성을 도모할 수 없어 기 적용되는 철근망을 대체할 방안이 강구되고있는 현실이다.However, existing cast-in-place piles have low noise and can penetrate to the required depth required in the field, but problems due to securing space and supply of equipment when assembling reinforcing bars applied as reinforcement for compression and shear Due to the complicated process that occurs during transportation, construction, etc., it takes a lot of manpower, time, and construction cost, and it is not only difficult to apply it in reality, but also the most fatal problem that can occur when concrete is laid by applying a hole larger than the maximum aggregate size In addition to the separation of phosphorus material and the convenience of construction is not achieved, the plan to replace the existing rebar network is being pursued.
또한, 보강재인 철근망은 적용되는 구멍의 개수를 쉽게 조절할 수 가 없고 적용할 현장타설말뚝의 설계 및 시공이 용이하지 않으며 특히, 조립식 철근망은 현장에서 수작업에 의해 제작되는 관계로 연결부분 등에서의 문제점이 발생할 수 있으며 현장에서 제작하여 수급되는 관계로 재료의 불량률이 높아 수직력 작용시 말뚝의 축압축 단면력이 약한단점이 있고 철근망의 조립 및 관리가 어려워 현장에서는 별도의 예산항목을 산정하여 품질관리를 하고 있다.In addition, the reinforcement steel is not easy to control the number of holes to be applied, and it is not easy to design and construct the site-casting pile to be applied.In particular, the prefabricated reinforcing steel network is manufactured by hand in the field, Problems may occur, and due to the manufacturing and supply in the field, high defect rate of materials, weak axial compressive cross-sectional force of pile when vertical force is applied, and difficult to assemble and manage reinforcing bar network. Is doing.
따라서, 상기와 같은 문제점을 해소하기 위한 본 발명의 목적은 현장타설말뚝 내부에 철근망 대신 유공강관을 사용함으로써 수직력 작용시 강관의 링형태를 장력(Hoop Tension)이 철근망에 비해 추가저항력으로 발휘되므로 말뚝의 축압축 단면력을 증진시킨 유공강관을 이용한 현장타설말뚝을 제공하는 것이다.Accordingly, an object of the present invention for solving the above problems is to use the perforated steel pipe instead of the reinforcing steel net in the cast-in-place pile to exhibit the ring shape of the steel pipe as an additional resistance force compared to the reinforcing steel bar when the vertical force is applied. Therefore, it is to provide a cast-in-place pile using a perforated steel pipe to increase the axial compression section force of the pile.
본 발명의 또 다른 목적은 수작업으로 제작되는 기 철근망 대신 결함이 없도록 공장에서 제작된 유공강관을 적용함으로써 규일한 현장타설말뚝을 시공할 수 있을 뿐만아니라, 시공시 간편한 작업을 가능케 하여 기존의 철근망 조립에 요구되는 인력과 시간을 절약하는 것이다.Still another object of the present invention is to apply a perforated steel pipe manufactured in a factory so that there are no defects instead of a machined steel net manufactured by hand, and it is possible to construct a unique site-placement pile, and also to enable easy work during construction. It saves the manpower and time required for network assembly.

It is a construction method of on-site placing pile (3) applying perforated steel pipe (1).
따라서 상기 본 발명은 건축구조물의 침하를 방지하기 위하여 지반에 기초작업으로 천공기를 통해 일정간격으로 복수개의 말뚝(3)을 굴착하는데 이때 굴착되는 말뚝(3) 내부에 삽입되는 강관(1)에 최대골재수치보다 큰 구멍을 굴착하여 콘크리트(4) 타설시 콘크리트(4)가 쉽게 드나들 수 있도록 하며, 단 강재의 구조적 내하성에 영향을 미치지 않아야 한다.Therefore, the present invention is to excavate a plurality of piles (3) at a predetermined interval through a perforator in the ground work to prevent the settlement of the building structure at this time is the maximum in the steel pipe (1) inserted into the excavated pile (3) Holes larger than the aggregate value are excavated so that the concrete (4) can easily pass through when placing concrete (4), but should not affect the structural load resistance of the steel.
상기 굴착된 말뚝(3) 내부에 압축 및 전단에 대한 보강재로서 유공강관(1)을 삽입하는데 직경은 말뚝보다 다소 작게하고 표면에 길이방향으로 관통되는 복수개의 통공(2)이 형성된다.Into the excavated pile (3) is inserted into the perforated steel pipe (1) as a reinforcement for compression and shear, the diameter is somewhat smaller than the pile is formed with a plurality of through holes (2) penetrating in the longitudinal direction on the surface.
즉 상기 말뚝(3) 내부에 삽입된 유공강관(3)에 콘크리트(4)를 타설시에 콘크리트(4)는 통공(2)을 통해 말뚝(3) 내부로 고르게 밀실충진되면서 유공강관(1)과 콘크리트(4)의 부착력을 증가시킬 수 있을 뿐만아니라 최대골재의 크기보다 큰 통공(2)을 적용함으로써 콘크리트(4) 타설시 발생할 수 있는 재료의 분리를 방지하며 유공강관(1) 자체를 공장에서 제작하여 규격화된 제품을 제공하고, 아울러 강관(1)의 두께 및 적용되는 통공(2)의 갯수를 조절하므로 현장타설말뚝(3)의 설계 및 시공상 편의성을 도모한다.That is, when the concrete 4 is poured into the perforated steel pipe 3 inserted into the pile 3, the concrete 4 is tightly packed into the pile 3 through the through hole 2 and the perforated steel pipe 1. Not only can increase the adhesion of concrete and concrete (4) but also prevents separation of materials that can occur when concrete (4) is placed by applying a through hole (2) larger than the size of the maximum aggregate. Providing a standardized product by manufacturing in addition to, and adjusts the thickness of the steel pipe (1) and the number of applied through holes (2) to facilitate the design and construction convenience of the site-casting pile (3).
또한, 유공강관(1)은 길이방향으로 관의 형태이므로 수직력 작용시 링형태에 따른 장력(Hoop Tension)이 철근망에 비해 추가적항력으로 발휘되므로 말뚝(3)의 축압축단면력을 증가시킬 수 있다.In addition, since the perforated steel pipe (1) is in the form of a pipe in the longitudinal direction (Hoop Tension) according to the ring shape when the vertical force is applied as an additional drag force compared to the reinforcing bar network can increase the axial compression section force of the pile (3) .
또한, 말뚝(3) 내부에 따라서 유공강관(1)을 삽입시 설치 부위 및 길이를 조정하여 설치함으로서 효율성을 증대시킨 구조이다.In addition, by adjusting the installation site and length when inserting the perforated steel pipe (1) in accordance with the pile (3) is a structure that increased the efficiency.
이상에서 설명한 바와 같이 본 발명은 관의 형태이면서 표면에 복수개의 통공이 형성되어 콘크리트와 부착력 증가와 재료의 분리를 방지하면서 수직력 작용시 Hoop Tension이 철근망에 비해 추가저항력으로 발휘되므로 말뚝의 축압축 단면력을 증가시킬 수 있으며, 현재 소음 ·진동에 의한 공사제한을 받는 곳에서 널리 사용될 수 있을 것이다.As described above, the present invention is in the form of a pipe and a plurality of through holes are formed on the surface, while increasing the adhesion and concrete and prevent separation of materials, while the vertical force acts as the hoop tension is exerted as an additional resistance force compared to the reinforcing bar pile axial compression It can increase the sectional force and can be widely used in places where current construction is restricted by noise and vibration.
또한, 기존의 철근망을 유공강관으로 대체하므로써 철근망 조립에 요구되는 인력과 시간으로 발생되는 비용을 절감할 수 있다.In addition, by replacing the existing rebar network with perforated steel pipe, it is possible to reduce the cost incurred by manpower and time required to assemble the rebar network.
따라서, 본 발명기술을 현재 가장 많이 적용되고 있는 대구경 현장타설말뚝 뿐만아니라 중 소구경 현장타설말뚝에도 적용 가능하며, 이를 활용시 현저한 공기단축 및 기술적 안정성 및 막대한 공사비 절감효과를 기대할 수 있을 것이다.Therefore, the present invention can be applied not only to large-diameter on-site casting piles, which are currently applied to the present invention, but also to medium- and small-diameter on-site casting piles.
한편, 본 발명은 그에 관한 최선의 실시예를 예거하였으나, 이에 한정되는 것은 아니며, 첨부된 청구범위에 국한되어 본 발명의 범위를 벗어나지 않고 실시될 수 있다면 지금까지 설명된 실시예의 변경을 고려하여 볼 수 있다.On the other hand, the present invention exemplified the best embodiment thereof, but is not limited to this, if limited to the appended claims can be carried out without departing from the scope of the invention in view of the modifications of the embodiments described so far Can be.
