Each front plate has first, second, and third through holes. The nail members penetrate through the first through holes. The reinforcing materials are inserted into the second and third through holes and restrict the front plates. The anchoring members anchor the front plates to the nail members.

Description

3방향 구속타입 전면판을 갖는 쏘일네일 장치{THE SOIL-NAILING APPARATUS}SOIL-NAILING APPARATUS with three-way restraint type faceplate

본 발명은 3방향 구속타입 전면판을 갖는 쏘일네일 장치에 관한 것으로, 보다 상세히 설명하면 X,Y,Z축 3방향으로 구속 가능한 전면판을 통해 이웃하는 전면판들과 연동되게 일체화시켜 사면에서 국부적인 거동이 발생시, 국부변형이 발생하지 않는 구역과 연동되어 힘을 받음으로 인해 보강사면을 안정적으로 보호하는 3방향 구속타입 전면판을 갖는 쏘일네일 장치에 관한 것이다.The present invention relates to a soil nail device having a three-way restraint type front plate, more specifically, it is localized in four sides by integrating and interlocking with neighboring front plates through a front plate that can be restrained in three directions of X, Y, and Z axes. When the phosphorus behavior occurs, it relates to a soil nail device having a three-way restrained type front plate to reliably protect the reinforcement slope due to the force in connection with the area where no local deformation occurs.

일반적으로 쏘일네일 장치는 보강할 지반을 천공하여 이형철근, 스틸바, 스틸파이프, 대나무 등의 네일부재를 전면판을 관통시켜 넣고 천공의 내부에 시멘트 밀크로 충진한 후, 전면판들을 와이어로 묶어 지반을 보강하는 장치이다.In general, the nail nail device drills the ground to be reinforced, penetrates the nail members such as deformed steel, steel bars, steel pipes, bamboos, etc. through the front plate, and fills the interior of the punch with cement milk, and then binds the front plates with wire. It is a device to reinforce the ground.

즉, 쏘일네일 장치는 보강될 사면에 인장응력, 전단응력 및 휨모멘트에 저항할 수 있는 네일부재를 일정한 간격으로 삽입하여 원지반의 전단강도를 증진시키고, 발생변위를 억제하며 굴착공사 도중이나 완료 후에 예상되는 이완을 제한하는 공법으로서 많은 연구가 있어왔다.That is, the nail nail device inserts nail members capable of resisting tensile stress, shear stress and bending moment at regular intervals on the slope to be reinforced to enhance shear strength of the base, restrain the displacement, and during or after excavation work. There has been much research as a method to limit the expected relaxation.

예컨대, 한국등록특허공보 제10-0698758호에는 네일링 공법에 의해 보강된 지반 절취면 표면에 철근콘크리트 벽체가 일체화 시공되는 합벽식 옹벽으로서, 네일링 공법에 의해 일단부가 지반에 정착되면서 타단부가 지반 절취면 표면으로 돌출되는 네일; 상기 네일의 타단부를 관통하여 설치되어 네일 주변부의 지반 절취면 표면을 누르면서 네일에 고정되는 지압판; 수직철근과 수평철근이 교차 배근되는 것으로, 상기 돌출된 네일 타단부에 걸쳐지도록 배치되는 철근망; 및, 상기 돌출된 네일의 타단부, 철근망 및 지압판이 매설되도록 타설 양생되는 콘크리트;를 포함하여 구성된 네일보강 합벽식 옹벽 및 그 구축방법이 공개되어 있다.For example, Korean Patent Publication No. 10-0698758 is a plywood retaining wall in which reinforced concrete walls are integrally constructed on the surface of a ground cut surface reinforced by a nailing method. Nails projecting onto the ground cut surface; An acupressure plate installed through the other end of the nail and fixed to the nail while pressing the surface of the ground surface of the nail; Reinforcing bars and vertical reinforcing bars are cross-reinforced, the reinforcing bar is disposed so as to span the other end of the protruding nail; And a reinforcing nail retaining wall including the other end of the protruding nail, reinforcing bar and acupressure plate is embedded to be cured to be embedded.

그러나, 상기 종래 기술은 인장응력, 전단응력, 및 휨 모멘트값이 삽입되는 네일부재의 수에 따라 편차가 크며 각각의 네일부재를 고정하는 전면판들이 연동되지 않으며, 전면판들을 와이어로 체결하여 결속력이 약할 뿐만 아니라, 작업이 복잡하여 공기가 길어지는 문제가 있다.However, the prior art has a large deviation according to the number of nail members into which tensile stress, shear stress, and bending moment value are inserted, and the front plates fixing each nail member are not interlocked. Not only is this weak, there is a problem that the work is complicated and the air is long.
