본 발명은 도로나 기타 토목공사에 의해 발생하는 사면(또는 옹벽)을 보강하기 위한 클러치셋 네일링 시스템과 그 시공방법에 관한 것으로, 좀 더 구체적으로 사면에 천공한 구멍에 앵커를 삽입한 다음 앵커를 확장시켜 천공홀에 고정되도록 하는 것에 있어서 종래에 비하여 매우 간단한 구성과 작동으로 앵커를 고정되도록 개선한 것이다.The present invention relates to a clutch set nailing system and a construction method for reinforcing a slope (or retaining wall) generated by roads or other civil works, and more specifically, inserting an anchor in a hole drilled in the slope It is improved to fix the anchor in a very simple configuration and operation as compared to the conventional to be fixed to the drilling hole by expanding.

주지된 바와 같이 토목공사 시 사면이나 옹벽 등을 보강하여 붕괴나 슬라이딩을 억제하기 위하여 안정공법으로 사면보강공법이 수행되고 있으며, 이러한 사면 안정공법은 시공목적에 따라, 활동력 감소공법, 저항력 증강 공법, 표면보호공법 등의 여러 가지로 구분되고, 이 중 저항력 증강의 대표적인 공법으로 락 볼트, 어스앵커, 소일 네일, 계단식 옹벽 등이 있다.As is well known, the slope reinforcement method is performed as a stabilization method to reinforce slopes and retaining walls to suppress collapse or sliding, and such slope stabilization methods can be used in accordance with the purpose of construction. The surface protection method is divided into various, such as a representative method of increasing the resistance of the lock bolt, earth anchor, soy nail, step retaining wall and the like.

이 중에서 소일 네일링 공법은 가장 널리 사용되는 공법의 하나로서, 원 지반에 보강재(네일 구조체)를 설치하여 원지반 강도를 최대한 이용하면서 복합보강 지반을 형성함으로써, 지반의 전단 및 인장강도를 증가시켜 변위를 억제시키고 지반의 이완을 방지시키는 공법이다.Among them, the Soil Nailing Method is one of the most widely used methods. By reinforcing material (nail structure) on the original ground, the composite reinforcement ground is formed while maximizing the strength of the ground, thereby increasing the shear and tensile strength of the ground and displacing it. It is a method of suppressing and preventing ground loosening.

이러한 소일 네일링 공법에 관한 종래 구성의 예로는 도 4의 예와 같은 특허 제448037호가 있는데, 살펴보면, 맨 앞에는 쐐기돌기(101)가 선단에 형성된 지지체(100)가 구성되고 그 옆에는 몇 개로 분할된 앵커본체(110)가 구성되며, 또한 테이퍼 압박구(120)와 철근 형태의 네일(130)이 연속으로 결합되어 네일(130)의 선단이 지지체(100)와 나사 결합되면 테이퍼 압박구(120)가 앵커본체(110)를 압착하여 앵커본체(110)가 분할되면서 벌어져 천공 홀의 내벽에 걸리도록 구성된 것이다.An example of the conventional configuration related to the soil nailing method is Patent No. 448037 as shown in the example of FIG. 4. Looking at the front, a support 100 having a wedge protrusion 101 formed at its tip is divided into several parts next to it. When the anchor body 110 is configured, and the tapered pressing hole 120 and the reinforcing nail 130 are continuously coupled, and the tip of the nail 130 is screwed with the support 100, the tapered pressing hole 120 ) Is compressed so that the anchor body 110 is divided while the anchor body 110 is divided to be caught on the inner wall of the drilled hole.

이러한 구성으로 된 종래 소일 네일링 공법에 의하면 네일(130)의 선단에 테이퍼 압박구(120)와 앵커본체(110) 및 지지체(100)가 결합된 상태에서 천공 홀에 삽입한 다음, 네일(130)을 회전시켜 앵커본체(110)가 분할되면서 벌어지도록 나사 결합하여야 하는 것으로, 나사결합이 원활하게 이루어지도록 지지체(100)의 선단에는 나사결합이 이루어지는 동안 지지체(100)가 회전하지 않도록 천공 홀의 바닥과 마찰 되는 쐐기 돌기(101)가 반드시 구성되어야 하였다.According to the conventional soil nailing method having such a configuration, the taper pressing hole 120 and the anchor body 110 and the support body 100 are inserted into the drilling hole at the tip of the nail 130 and then the nail 130 Rotating the anchor body 110 is to be screwed to open while being divided, so that the screw coupling is made smoothly at the tip of the support 100, the bottom of the drilled hole so that the support 100 does not rotate during the screwing The wedge protrusion 101 which is rubbed with must It had to be constructed.

따라서 네일링 시스템의 구성에 비용과 시간이 많이 소요되고 네일(130)을 회전시키고 그에 따른 나사결합에 의해 앵커본체(110)가 벌어지면서 걸림이 완성되므로 시공시간이 많이 소요되는 단점도 있었다.Therefore, the construction of the nailing system takes a lot of cost and time, and the construction of the anchoring body 110 is widened by screwing the anchor body 110 by screwing accordingly, thus completing the construction time.

상기한 문제점을 감안하여 안출한 본 발명은 네일의 선단에 테이퍼 압박구와 지지체를 포함한 앵커본체를 결합한 상태로 천공 홀에 삽입한 다음, 종래기술에서와 같은 나사결합에 의한 앵커의 벌어지는 과정 없이, 간단한 동작과 구성으로 신속하게 앵커본체를 벌어지게(확개) 하여, 전체적으로 간단한 구성과 견고한 사면보강과 신속한 작업이 가능하도록 함을 목적으로 하는 것이다.The present invention devised in view of the above problems is inserted into the drilled hole in the state in which the anchor body including the tapered pressure port and the support at the tip of the nail, and then, without the process of opening the anchor by screwing as in the prior art, It aims to open (expand) the anchor body quickly by operation and configuration, so as to enable simple construction, solid slope reinforcement and rapid work as a whole.

Construction can be done by.

또 종래의 시스템과 같이 네일을 나사 결합방식으로 앵커 본체를 확개(발개) 하고자 할 때는 지지체가 회전하지 않도록 하는 쐐기 돌기를 반드시 형성하여야 했으나, 본원발명에 의하면 미리 지지체와 완전하게 결합하여 준 다음 시공을 하고, 네일을 회전시킬 필요가 없으므로 그러한 쐐기돌기와 같은 구성이 필요 없게 되어 제조가 간편해지고 구성이 간단해지는 효과를 얻게 된다.In addition, in order to expand (open) the anchor body by screwing a nail as in the conventional system, a wedge protrusion must be formed so that the support does not rotate. According to the present invention, the construction is performed after fully coupling with the support. And since there is no need to rotate the nail, such a wedge does not need a configuration such that the production is simplified and the effect is simplified.

이러한 본 발명의 네일링 시스템의 작용을 시공방법에 의하여 살펴보면 다음과 같다.Looking at the operation of the nailing system of the present invention by the construction method as follows.

본 발명에 의한 네일링 시스템은 공지된 시공방법과 대동소이한 것이기는 하나, 본 발명은 본 발명만의 시공법 적용을 위한 사면보강용 클러치 셋 네일링 시스템을 개발하고 준비하여 이를 시공하는 특징적인 공법으로서, 이를 구체적으로 설명하면, 클러치 셋 네일링 시스템 준비공정(S1)과, 네일링 시스템을 천공 홀 내부에 삽입하는 네일링 시스탬 삽입공정(S2)과, 작동레버의 작동으로 걸고리가 해제되어 이탈되는 걸고리 이탈공정(S3) 및 스프링의 탄성복원력에 의하여 앵커본체의 블레이드가 벌어지는 앵커본체 발개(확개) 공정(S4) 순으로 시공하게 되는 것이다.
이와 같은 특징적인 공정으로 이루어진 본원 발명의 시공법을 구체적으로 설명하면, 우선 클러치 셋 네일링 시스템을 준비하는 공정(S1)으로서, 코일스프링(50)과 테이퍼 압박구(30)와 앵커본체(20) 및 지지체(10)가 일체로 결합된 상태의 네일(40)을 준비한 후, 대상 지반인 사면에 형성된 천공홀(1)의 내부에 코일스프링(50)과 테이퍼 압박구(30)와 앵커본체(20) 및 지지체(10)가 일체로 결합된 상태의 네일(40)을 삽입하는 네일링 시스템 삽입공정(S2)을 실시한다.
Although the nailing system according to the present invention is very similar to a known construction method, the present invention is a characteristic construction method for developing and preparing a clutch set nailing system for slope reinforcement for application of the construction method of the present invention only. As described in detail, the clutch set nailing system preparation step (S1), the nailing system insertion process (S2) for inserting the nailing system into the drilling hole, and the hook is released by the operation of the operating lever It will be constructed in the order of the hook separation process (S3) and the anchor body opening (expansion) process (S4) in which the blade of the anchor body is opened by the elastic restoring force of the spring.
Referring specifically to the construction method of the present invention made of such a characteristic process, first, as a step (S1) for preparing a clutch set nailing system, the coil spring 50, the tapered pressure port 30 and the anchor body 20 And after preparing the nail 40 in a state in which the support 10 is integrally coupled, the coil spring 50, the tapered pressure port 30 and the anchor body (1) in the perforated hole (1) formed on the slope of the target ground ( 20) and a nailing system insertion process S2 for inserting the nail 40 in a state in which the support 10 is integrally coupled thereto.

그 후 작동와이어(46)을 당겨 작동레버(44)가 순간적으로 젖혀지면서 끝단부가 들려 올라가게 되고, 이로 인하여 걸고리(47)의 끝단이 걸림턱(43)으로부터 이탈되어 걸고리(47)는 받침부(42)와 테이퍼 압박구(30)로부터 완전히 이탈되게 하는 걸고리 이탈공정(S3)이 실시된다.Thereafter, by pulling the operation wire 46, the operation lever 44 is lifted momentarily, the end is lifted up, and thus the end of the hook 47 is separated from the latching jaw 43 so that the hook 47 is supported. Hook disengagement step S3 for completely disengaging from the 42 and the tapered pressure tool 30 is performed.

이러한 걸고리(47)의 이탈에 의해 코일스프링(50)의 억제되어 있던 힘(탄성 복원력)이 순간적으로 작용함에 의해 테이퍼 압박구(30)가 앵커본체(20) 방향으로 강력한 힘을 가하게 되며, 이러한 힘에 의해 앵커본체(20)가 벌어지면서 선단의 블레이드(21)는 천공 홀(1) 내벽을 파고들면서 걸림 되고, 고정되는 앵커본체 발개(확개) 공정(S4) 순으로 시공이 완료되는 것이다.Due to the detachment of the hooks 47, the restrained force (elastic restoring force) of the coil spring 50 acts momentarily, and thus the tapered pressure port 30 exerts a strong force toward the anchor body 20. As the anchor body 20 is opened by the force, the blade 21 at the tip is caught while digging into the inner wall of the drilling hole 1, and the construction is completed in the order of anchor body opening (expansion) process (S4) being fixed.

이러한 시공과 작용으로 인하여 네일링 시스템의 고정이 이루어지는 것이고, 상기 동작에 의해 완전한 고정이 이루어지지 못할 경우에는 네일(40)을 천공 홀(1) 바깥 방향으로 조금 당겨주면 블레이드(21) 부분이 더욱 깊숙히 천공 홀(1) 내면을 파고들면서 완전한 고정이 이루어진다. Such The nailing system is fixed due to the construction and action. If the nailing system is not completely fixed by the above operation, the blade 21 is further deepened by pulling the nail 40 slightly outward from the punching hole 1. Complete fixation is achieved by digging into the inner surface of the drill hole 1.

상기와 같은 시공과정을 거쳐 완전한 고정이 이루어진 다음에는 그라우팅 작업을 실시하여 천공 홀(1)의 내부에 그라우트를 채워 굳힘으로써 천공 홀 내부에 네일링 시스템이 완전히 고정되는 상태가 되도록 함으로서 시공이 완료된다.After complete fixing through the above-described construction process, the grouting work is performed to fill the grout in the drilling hole 1 so that the nailing system is completely fixed inside the drilling hole. .

이러한 본 발명의 네일링 시스템과 그에 의한 시공방법에 의하면, According to the nailing system and the construction method of the present invention,

종래기술에서와 같은 과정, 즉 앵커본체(20)가 천공홀(1) 내벽에 걸리도록 하기 위하여 네일(40)을 힘들게 회전시켜 지지체(20)와 결합시키는 동작이 필요 없게 되고, 작동와이어(46)를 당겨주는 간편한 동작만으로 걸고리(47)가 이탈되면서 강력한 코일스프링(50)의 힘(탄성복원력)으로 앵커본체(20)를 벌리게 되면서 순간적인 고정이 이루어지는 것으로, 종래기술에 비하여 매우 간단한 동작과 편리한 공정에 의해 시공이 이루어질 수 있는 것이다.The same process as in the prior art, that is, the anchor body 20 is hard to rotate the nail 40 in order to be caught on the inner wall of the hole (1), there is no need for the operation to combine with the support 20, the operation wire 46 As the hook ring 47 is separated by a simple operation of pulling), the anchor body 20 is opened by the force (elastic restoring force) of the strong coil spring 50, and instantaneous fixation is made. Construction can be made by a convenient process.

또한, 종래기술의 네일링 시스템에 의하면 네일을 회전시켜 지지체와 결합시킴에 의해 앵커본체를 벌리도록 되어 있으므로 이로 인해 네일을 나사 결합할 때 지지체가 회전하지 않도록 지지체에는 반드시 쐐기 돌기를 형성하여야 했으나, 본원발명의 경우, 이와는 달리 완전히 조립된 네일링 시스템을 천공 홀(1) 내부에 삽입한 다음, 작동와이어(46)을 당겨 간편히 시공하는 방식을 취하고 있어, 종래 기술에서와 같은 네일을 천공 내부에 삽입한 후, 네일을 회전시킬 필요가 없으므로, 지지체에 쐐기 돌기를 구성할 필요가 없게 되므로 제조가 간편해지고 구성이 간단해지는 장점도 갖게 된다.In addition, according to the nailing system of the prior art, the anchor body is opened by engaging the support by rotating the nail, so that the wedge protrusion must be formed on the support so that the support does not rotate when screwing the nail. In the present invention, in contrast, the fully assembled nailing system is inserted into the drilling hole 1, and then the operation wire 46 is simply pulled to construct the construction. After insertion, there is no need to rotate the nail, so there is no need to configure the wedge projections on the support, so that the manufacturing is simplified and the configuration is simplified.
