본 고안은 소일네일링(soil nailing) 공법용 비제거식 일체형 네일에 관한 것으로, 더욱 상세하게는 원통형의 몸체 외주면에 다수의 돌기가 방사형으로 형성되고, 상기 몸체의 전단부와 후단부에는 각각 수나사부와 암나사부가 형성되어, 다수의 네일을 결합할 수 있어 길이를 자유로이 조절할 수 있으며, 상기 네일은 부식이 용이한 플라스틱 입자와 토목섬유로 형성하여, 지중에 삽입된 네일을 차후에 인발하여 제거하지 않아도 자연부식되어 소멸되도록 한 소일네일링 공법용 네일에 관한 것이다.The present invention relates to a non-removable one-piece nail for the soil nailing method, more specifically, a plurality of projections are formed radially on the outer peripheral surface of the cylindrical body, each of the male screw portion on the front end and the rear end of the body And female thread is formed, can be combined with a plurality of nails can be adjusted freely, the nail is formed of plastic particles and geosynthetic fiber, which is easy to corrode, so that the nail inserted in the ground does not have to be removed later The present invention relates to a nail for a soil nailing method that is caused to corrode and disappear.
일반적으로 소일네일링(soil nailing) 공법이란 절취사면이 토사나 리핑암일 때 사면의 붕괴를 방지하기 위해 보강하는 공법으로서 비탈면이나 터파기 굴착면을 자립할 수 있는 안정높이로 굴착함과 동시에 숏크리트(shotcrete)로 표면보호면을 형성하고 굴착면을 천공하여 네일을 삽입한 후 그라우팅을 실시하여 보강토체를 조성하는 방법으로, 터파기, 흙막이, 철도 및 도로에 인접한 자연사면 및 인공사면의 보강, 지하구조물 및 터널 등과 같은 토목 관련 시설물 축조, 기존 옹벽의 보수 및 옹벽 설치공사에서 주로 이용되고 있다.Generally, the soil nailing method is a reinforcing method to prevent the collapse of the slope when the cut slope is soil or ripping arm, and excavates at a stable height that can stand the slope or the excavation surface at the same time. shotcrete) to form the surface protection surface and drill the excavation surface to insert nails and grout to form reinforcement soils, reinforcement of natural and artificial slopes adjacent to trenches, mudstones, railways and roads, underground It is mainly used in construction of civil engineering facilities such as structures and tunnels, repair of existing retaining walls, and installation of retaining walls.
그러나, 종래의 소일네일링 공법은 도 1 내지 도 1b에서 보는 바와 같이, 굴 착면에 케이싱 천공을 하고, 이 케이싱 내부에 보강체를 삽입한 다음, 상기 케이싱을 인발하고, 다시 주입관을 삽입하여 상기 보강체를 중심으로 콘크리트를 주입하여 그라우팅을 실시한 후 주입된 콘크리트가 양생되면 굴착면에 돌출된 보강체의 끝단에 지압판을 설치하고 너트를 체결하여 토압으로부터 굴착면을 지지케 함으로써 굴착면의 붕괴를 방지하였다. However, in the conventional small nailing method, as shown in Figs. 1 to 1b, the casing is drilled in the excavation surface, the reinforcement is inserted into the casing, the casing is drawn out, and the injection tube is inserted again. When the injected concrete is cured after injecting concrete around the reinforcement, when the injected concrete is cured, it installs a pressure plate at the end of the reinforcement projecting on the excavation surface and tightens the nut to support the excavation surface from earth pressure.

However, the grouting made it almost impossible to remove the nail. Therefore, the nail inserted into the land owned by others caused frequent disputes about the occupancy fee, and the problem of obstacles in the development of underground spaces such as waterworks, sewerage, conduits, cables, and subways.
상술한 바와 같은 문제점을 해결하기 위하여, 본 고안은 소일네일링 공법용 네일을 부식이 가능한 재질로 형성하고, 원통형 네일의 외주면에는 다수의 돌기를 형성하여 그라우팅재와 네일의 마찰저항을 극대화시키며, 상기 네일의 전단부와 후단부에는 각각 수나사부와 암나사부를 형성하여 결합 및 분리가 용이하도록 함으로써 자유로이 네일의 길이조절을 할 수 있도록 하고, 종래의 소일네일링 공법에서 보강체 삽입공정과 주입관 삽입공정을 생략하고도 시공이 가능하므로 공기를 단축 할 수 있을 뿐 아니라, 차후 지중에 삽입된 네일을 제거하지 않아도 자연부식되어 소멸되므로 타인소유대지의 재산권 침해 및 지하공간개발작업에서의 장애문제 등을 원천적으로 해소할 수 있는 소일네일링 공법용 비제거식 일체형 네일을 제공하는 데 그 목적이 있다.In order to solve the problems as described above, the present invention is to form a nail for a nail nailing method with a corrosive material, to maximize the frictional resistance of the grouting material and nail by forming a plurality of projections on the outer peripheral surface of the cylindrical nail, The front and rear ends of the nail are formed with male threads and female threads, respectively, so that the length of the nail can be freely adjusted by easy coupling and separation, and the reinforcement insertion process and the injection tube are inserted in the conventional small nailing method. The construction can be done even if the process is omitted, and not only shortens the air, but also causes natural corrosion and disappears without removing nails inserted into the ground. The purpose is to provide a non-removable one-piece nail for the soil nailing process that can be solved at the source. have.
전술한 바와 같은 목적을 달성하기 위하여, 본 고안상의 소일네일링 공법용 비제거식 일체형 네일은, 원통형 몸체의 외주면에 다수의 돌기가 형성되고, 상기 몸체의 전단부와 후단부에는 각각 수나사부와 암나사부가 형성되며, 또한 네일의 재질은 소정의 네일 수명이 다한 후에 지중에서 부식이 용이한 부식성 섬유로 이루어진 것을 특징으로 한다. In order to achieve the object as described above, the non-removable one-piece nail for the small nailing method of the present invention, a plurality of projections are formed on the outer peripheral surface of the cylindrical body, the male and female threads on the front end and the rear end of the body, respectively In addition, the material of the nail is characterized in that made of corrosive fibers that are easily corroded in the soil after a predetermined nail life.
