나선형 다철근 네일 {Spiral poly bar nail}Spiral poly bar nail

본 고안은 나선형 다철근 네일에 관한 것으로, 보다 상세하게는 전단저항력을 증가시킬 뿐만 아니라 필요에 간편하게 설치할 있도록 하는 나선형 다철근 네일에 관한 것이다.
The present invention relates to a spiral multi-bar nail, and more particularly to a spiral multi-bar nail to increase the shear resistance as well as to easily install as needed.

일반적으로 사면의 보강공법으로는 네일링공법이나 앵커공법을 주로 사용하였으며, 록볼트공법과 네일링공법은 이형철근이나 강봉을 지중에 삽입하고 공벽과 보강재 사이의 공간을 주입재로 그라우팅하여 설치하는 것으로, 설치 후 발생되는 지중변위가 지압판에 전달되어 보강재의 인장력이나 전단력으로 저항하게 하는 구조이다.In general, the reinforcing method of slope is mainly used nailing method or anchoring method, and rock bolt method and nailing method are installed by inserting a deformed reinforcing bar or steel bar into the ground and grouting the space between the ball wall and the reinforcement with injection material. The underground displacement generated after installation is transmitted to the pressure plate to resist the tensile or shear force of the reinforcement.

여기서 앵커공법은 인장재로 강봉이나 강연선을 주로 사용하고 정착구간의 주입재와 앵커체 또는 앵커체를 포함한 주입재와 공벽과의 마찰저항력을 이용하여 외부에서 인장력을 도입하고 자유구간에 설치된 인장재로 인장하중을 지압판에 전달시켜 사면이나 수직굴착면의 안정성을 증가시키는 공법이다.Here, anchor method mainly uses steel bar or strand as tension material, and introduces tensile force from outside by using friction material between injection material of anchorage section and injection material including anchor body or anchor body and hollow wall and tension load with tension material installed in free section. It is a method to increase the stability of slope or vertical excavation surface by transferring to the pressure plate.

이러한 앵커공법은 정착구간내의 마찰저항의 작용에 따라 마찰형과 지압형으로 대별되고, 마찰형앵커는 다시 마찰형과 압축형으로 구분된다. The anchor method is roughly divided into friction type and acupressure type according to the action of frictional resistance in the fixing section, and the friction type anchor is divided into friction type and compression type.

나아가 네일링공법이나 앵커공법은 단순히 정착구간내에서 마찰저항이나Furthermore, the nailing method or anchoring method is simply used to

지압력과 보강재나 인장재의 인장력이나 전단력을 이용하고 있다.The bearing force and the tension or shear force of the reinforcement and tension member are used.

그러나 기존의 록볼트공법 또는 네일링공법이나 앵커공법에서 붕괴가 발생된 경우를 살펴보면, 토질정수의 불확실성, 예상파괴면에서의 부적절한 예측, 부적당한 설치간격, 인장재료나 보강재의 부적절한 선택, 정착장 계산의 부적합, 과도한 지하수압의 작용 등의 여러 가지 원인이 하나 또는 복합적으로 작용되어 재붕괴가 발생되는 것으로, 특히 대부분의 붕괴사고를 살펴보면 예상파괴면의 전단저항력 부족으로 보강재의 파단 또는 과도한 휨현상이 발생되는 점을 감안하면 붕괴 방지를 위한 전단력의 보강이 시급한 실정이다.
However, in the case of the collapse of the existing rock bolt method, nailing method or anchor method, the uncertainty of soil constant, inadequate prediction in predicted fracture surface, inadequate installation interval, inadequate selection of tensile material or reinforcement, anchorage One or a combination of reasons, such as inadequate calculation and excessive groundwater pressure, may cause re-decay. In particular, most collapses result in the failure of shear resistance or excessive bending due to the lack of shear resistance at the expected fracture surface. Considering the fact that it is necessary to reinforce the shear force to prevent collapse.

따라서 본 고안의 주 목적은 이형철근에 간편하고 편리하게 전단보강부재를 결합하여 현장 지반여건이나 절개면이나 굴착면의 파괴형태 등을 감안하여 효과적으로 전단력을 보강할 수 있도록 하는 나선형 다철근 네일을 제공하는 데 있다.
