본 발명은 소일네일링의 네일선단정착구에 관한 것으로, 더욱 상세하게는 다수의 정착날개가 힌지결합되어 설치된 네일선단정착구가 네일의 일측 끝단에 설치되고, 네일선단정착구가 설치된 네일을 사면의 앵커공에 삽입한 후, 네일선단정착구에 힌지결합되어 있는 다수의 정착날개가 외부로부터 유입되는 높은 압력의 압축공기에 의해 앵커공 벽면측으로 힌지축을 기준으로 회동되어 펼쳐져 고정됨으로써, 그라우팅재를 주입하기전에 인장이 가능하여 네일이 앵커공의 축선상의 중심부에 정확히 위치되도록 시공이 가능하고, 이후, 앵커공의 네일선단정착구가 삽입된 앵커공 내부로 그라우팅재를 주입 경화시켜 더욱 견고한 인장응력, 전단응력 및 휨모멘트에 저항할 수 있는 소일네일링의 네일선단정착구에 관한 것이다. The present invention relates to a nail tip anchorage of the nail nailing, and more specifically, a nail tip anchorage is installed in one end of the nail is installed by a plurality of fixing wings hinged, the anchor hole of the slope of the nail is installed After inserting into the nail, the fixing blades, which are hinged to the nail tip fixing holes, are rotated and fixed with respect to the hinge axis to the anchor hole wall by high pressure compressed air coming in from the outside, and are fixed before injecting the grouting material. It is possible to construct so that the nail is precisely positioned in the center of the anchor hole axis, and then the injection of the grouting material into the anchor hole into which the anchor tip fixing hole of the anchor hole is inserted, thereby further strengthening tensile stress, shear stress and bending The present invention relates to a nail tip anchorage stopper of a soil nailing capable of resisting a moment.

일반적으로 터파기, 흙막이, 철도 및 도로에 인접한 자연 및 인공사면의 보강, 지하구조물 및 터널 등과 같은 토목 관련 시설물 축조에 필요한 굴착 지보체 계, 기존 옹벽의 보수 및 옹벽을 설치하는 공사에 사용되는 소일네일링(soil-nailing method)은 지반의 붕괴와 균열이 쉽게 일어날 수 있는 토사나 토사와 암벽이 혼조된 연약지반인 경우, 굴착면이나 주변의 인접한 지반이 균열되고 무너지는 현상이 발생되는 위험을 사전에 예방하기 위한 안전조치로서 굴토 또는 절토 과정을 통하여 일련의 보강작업이 이루어지는 것으로, 비탈면이나 터파기 굴착면을 자립할 수 있는 안정높이로 굴착함과 동시에 숏크리트(shotcrete; 뿜어 붙이기 콘크리트)로 표면보호면을 시공하고 굴착배면을 천공하여 철근이나 와이어등의 인장응력, 전단응력 및 휨모멘트에 저항 할 수 있는네일(nail)을 삽입한 후, 그라우팅하여 보강토체를 조성함에 따라 연약지반의 전단저항력을 향상시켜 굴착한 연약지반에서 발생할 수 있는 균열이나 붕괴 등의 문제점을 해결하여 터파기공사 작업의 안정성을 도모하는 것이다. Soils generally used for construction of excavation support systems, repair of existing retaining walls, and installation of retaining walls required for construction of civil engineering-related facilities such as reinforcement of natural and man-made slopes adjacent to trenches, muds, railways and roads, underground structures and tunnels. Nailing (soil-nailing method) has the risk of cracking and collapsing of the excavation surface or adjacent adjacent ground in the case of soft ground where soil or soil and rock walls are easily broken and cracked. As a safety measure to prevent in advance, a series of reinforcement works are carried out through the process of excavation or cutting, and the surface is shot by shotcrete while simultaneously excavating the slope or excavation surface to a stable height that can stand on its own. Construct protective surface and drill excavation back surface to resist tensile stress, shear stress and bending moment of rebar and wire. After inserting nails that can be inserted, grouting to reinforce the soil, improve the shear resistance of the soft ground, and solve the problems such as cracks and collapse that may occur in the excavated soft ground. It is to plan.

상술한 바와 같은 종래의 소일네일링의 시공방법을 살펴보면, 지정된 굴착심도 만큼 굴착하여 원 지반이 자립하는지 확인된 후, 굴착 즉시 원 지반의 이완을 막기 위해 굴착면에 숏크리트가 타설된다. 이후, 요구되는 심도까지 천공기에 의해 천공된 앵커공 내부에 네일이 삽입된다. 이렇게 네일인 삽입된 앵커공 내부에 보강콘크리트로 그라우팅함으로써, 원 지반과의 부착면이 향상되도록 한다. 이때, 반영구적인 벽체가 형성되도록 철근콘크리트가 형성될 수 있다. 또한, 가 시설용으로 이용될 수 있으며, 이와 같은 경우에는 와이어메시 및 횡방향 철근이 설치된 후, 숏크리트 층과 네일이 고정체로 고정되고, 2차 숏크리트가 타설되어 벽체가 형성된 다. 즉, 원 지반의 부착력 증대시키기 위하여 2차 그라우팅이 실시되어 시공이 완료되는 것이다. 여기서, 네일과 숏크리트 층을 토사의 압력으로부터 지지하기 위하여 노출된 네일의 일단부에 고정체가 체결된다.Looking at the construction method of the conventional soil nailing as described above, after excavation by the designated excavation depth is confirmed whether the original ground is independent, shotcrete is placed on the excavation surface to prevent the loosening of the original ground immediately after excavation. Then, the nail is inserted into the anchor hole drilled by the puncher to the required depth. By grouting with reinforcement concrete in the anchor hole inserted into the nail, the attachment surface with the base is improved. At this time, the reinforced concrete may be formed to form a semi-permanent wall. In addition, it can be used for the facility, in this case, after the wire mesh and transverse reinforcing bar is installed, the shotcrete layer and the nail is fixed to the fixture, and the secondary shotcrete is poured to form a wall. That is, the secondary grouting is carried out to increase the adhesion of the original ground is completed construction. Here, the fixture is fastened to one end of the exposed nail to support the nail and shotcrete layers from the pressure of the soil.

그러나, 상기 종래의 소일네일링은 앵커공에 네일이 삽입되고 그라우트가 주입하여 경화시킨다. 이러한 방법은 단순히 앵커공에 끼워진 것에 불과하여 사면을 안정적으로 보강할 수 없으며, 비탈면의 상부측의 앵커공에 그라우팅 타설 후, 5~7일 경화시킨 다음 하부 앵커공에 네일삽입 및 그라우팅 작업이 이루어짐으로써, 시공 기간이 장기간 소요되는 문제점이 있었다.However, the conventional small nailing is a nail is inserted into the anchor hole and the grout is injected and hardened. This method is simply inserted in the anchor hole can not reinforce the slope stably, and after grouting is placed in the anchor hole of the upper side of the slope surface, it is cured for 5 to 7 days and then the nail insertion and grouting work is performed in the lower anchor hole As a result, there was a problem that the construction period takes a long time.

또한, 상기와 같은 종래 소일네일링 공법은 사면에 경사지게 형성된 앵커공에 네일을 삽입한 후 그라우팅재를 주입하여 경화하게 되는데, 이때, 앵커공은 사면으로부터 하향경사지게 천공되어 있어 앵커공에 삽입되는 네일의 선단부가 네일의 하중과 중력에 의해 앵커공 축선상의 중앙에 위치하지 않고 축선상의 하부면에 닿게 된다. 이와 같이 네일이 앵커공 축선상의 하부면에 하중과 중력에 의해 네일 선단부가 접하게 되면 그라우팅재를 앵커공 내부에 주입할 때 네일과 그라우팅재가 경화되는 과정에서 네일이 앵커공의 중심부에서 정착되지 않고 앵커공 축선상의 하부면으로 기울어져 접하여 있기 때문에 앵커공 내부에 주입되어 경화되는 그라우팅재와의 정착강도가 약화되는 문제점이 있었다. 그리고, 정착강도의 약화로 인한 사면의 전단 강도가 저하되어 지반의 균열이나 붕괴가 손쉽게 일어나며 철근이 부식 되어 유지보수비용의 증가 및 안전상의 문제점이 있었다.In addition, the conventional soil nailing method as described above is to insert a nail into the anchor hole formed inclined on the slope, and then to harden by injecting a grouting material, the anchor hole is drilled downward slope from the slope to be inserted into the anchor hole The tip of is not located at the center of the anchor hole axis by the nail load and gravity, but touches the lower surface of the axis. Thus, when the nail comes into contact with the lower surface of the anchor hole by load and gravity, when the nail is injected into the anchor hole, the nail is not settled at the center of the anchor hole while the nail and grouting material are cured. Since the inclined contact with the lower surface on the coaxial line has a problem that the fixing strength with the grouting material is injected into the anchor hole and hardened. In addition, the shear strength of the slope due to the weakening of the fixing strength is lowered, so that cracking or collapse of the ground easily occurs, the reinforcing steel is corroded, and there is an increase in maintenance cost and safety problems.

따라서, 본 발명은 상술한 바와 같은 문제점을 해결하기 위해 창출한 것으로, 터파기, 흙막이, 옹벽 등의 토목 공사시에 토사면의 사면이 붕괴되지 않도록 토사면의 사면을 안정화시키는 소일네일링 공법의 네일 선단부에 압축공기에 의해 확장되는 다수의 정착날개가 형성된 네일선단정착구가 구비되어 앵커공에 네일과 함께 삽입되고, 그라우팅재를 앵커공에 충진하기전에 인장함으로써, 네일이 앵커공의 축선상 중심부에 위치되어 수평을 유지한 상태로 시공된 후, 그라우팅재를 주입하여 경화시켜, 토압에 의한 변형이 현저히 적으며, 더욱 견고한 인장응력, 전단응력 및 휨모멘트에 저항할 수 있는 소일네일링의 네일선단정착구를 제공하는데 그 목적이 있다. Accordingly, the present invention has been made to solve the problems described above, and the method of soil nailing method to stabilize the slope of the soil surface so that the slope of the soil surface is not collapsed during the civil works such as trenches, retaining walls, retaining walls, etc. A nail tip anchorage with a plurality of fixing blades formed by the compressed air at the tip of the nail is inserted and inserted into the anchor hole together with the nail, and the nail is tensioned before the grouting material is filled into the anchor hole. Soil nailing nail which can be resisted by more powerful tensile stress, shear stress and bending moment by hardening by injecting and hardening by grouting material after being placed in the horizontal state. The purpose is to provide a tip anchorage.

또한, 본 발명은 네일선단부에 결합되는 네일선단정착구에 의해 시공기간의 단축되고 이로 인한 시공비의 절감과 더욱 안정된 사면의 보강으로 뛰어난 안전성이 확보됨과 함께 네일이 앵커공의 축선상 중심부에서 그라우팅재와 경화되어 철근의 부식이 방지되어 유지보수비용이 절감되는 소일네일링의 네일선단정착구를 제공하는데 또 다른 목적이 있다.In addition, the present invention is shortened the construction period by the nail tip fasteners are coupled to the nail tip, thereby reducing the construction cost and more stable by reinforcement of the more stable slope and with the nail grouting material in the center of the axis of the anchor hole Another purpose is to provide a nail tip anchoring point for the soil nailing that is hardened to prevent corrosion of the rebar, thereby reducing maintenance costs.

상술한 바와 같은 구성에 따른 본 발명의 소일네일링의 네일선단정착구의 작용 및 효과를 실시예를 통해 상세히 설명하기로 한다.The action and effect of the nail tip anchoring fastener of the present invention, according to the configuration as described above will be described in detail through the embodiment.

전술한 바와 같이 네일(N)과 네일커플링(C)가 네일선단정착구(100)의 네일결합부(140)에 결합된다. 여기서, 네일(N)는 네일결합부(140)의 중공의 끼움공(142)에 선단부가 억지끼움결합되고, 네일커플링(C)은 네일결합부(140)의 외연에 수나사(144)에 나사결합되어 네일(N)과 네일선단정창구(100)를 견고히 결합되도록 결합력을 유지한 상태로 선단부가 결합된다.As described above, the nail N and the nail coupling C are coupled to the nail coupling part 140 of the nail tip fitting 100. Here, the nail (N) is forcibly fitted to the tip portion of the hollow fitting hole 142 of the nail coupling portion 140, the nail coupling (C) to the male screw 144 on the outer edge of the nail coupling portion 140 The tip is coupled while maintaining the coupling force to be firmly coupled to the nail (N) and the nail tip window 100 by screwing.

이렇게 네일(N)와 네일커플링(C)의 선단부에 결합된 네일선단정착구(100)를 도 5에 도시된 바와 같이, 터파기, 흙막이, 철도 및 도로에 인접한 자연 및 인공사면의 보강, 지하구조물 및 터널 등과 같은 토목 관련 시설물 축조에 필요한 굴착 지보체계, 기존 옹벽의 보수 및 옹벽을 설치하는 공사 등에 천공된 앵커공(A)에 삽입한다. 다음으로, 네일선단정착구(100)가 결합된 네일(N)를 도 6에 도시된 바와 같이, 외부로부터 연장된 에어호스(110)를 통해 압축공기를 정착헤드부(130)의 압축공기 유입공(134)측으로 유입시킨다. As shown in FIG. 5, the nail tip anchoring aperture 100 coupled to the tip portion of the nail N and the nail coupling C, reinforcement of natural and artificial slopes adjacent to trenches, mudguards, railways and roads, and underground It is inserted into the anchor hole (A) drilled in the excavation support system required for the construction of civil engineering facilities such as structures and tunnels, repair of existing retaining walls, and construction of retaining walls. Next, as shown in FIG. 6, the nail N to which the nail tip fixing fitting 100 is coupled, compressed air is introduced into the compressed air through the air hose 110 extending from the outside of the fixing head unit 130. It flows into the (134) side.

이렇게 외부로부터 압축공기가 에어호스(110)을 통해 압축공기 유입공(134)를 통해 유입된 압축공기는 정착날개결합부(132) 내측으로 연통된 각각의 압축공기 분사공(136)을 통해 높은 압력으로 토출되게 된다. 이렇게 압축공기 분사공(136)을 통해 토출되는 압축공기는 정착날개결합부(132)에 힌지결합된 정착날개(120)의 일면을 높은 압력으로 밀게된다. The compressed air introduced from the outside through the compressed air inlet hole 134 through the air hose 110 is high through each of the compressed air injection holes 136 communicated to the inside of the fixing wing coupling unit 132. It is discharged under pressure. The compressed air discharged through the compressed air injection hole 136 is pushed to one side of the fixing blade 120 hinged to the fixing blade coupling portion 132 at a high pressure.

따라서, 압축공기가 높은 압력으로 압축공기 분사공(136)을 통해 정착날개(120)측으로 분사됨으로써, 정착날개결합부(132)의 힌지공(133)의 축선상에서 정착날개(120)가 앵커공(A)의 지중의 지면측으로 회동하게 된다. 이렇게 회동되는 정착날개(120)는 앵커공(A)의 지중의 지면측으로 정착날개(120)의 타측 예각으로 형성된 부분이 지면에 정착함과 동시에 외측에서 네일(N)를 인발한다. 이렇게 외부에서 정착날개(120)가 정착됨과 동시에 네일(N) 인발시 쐐기부재(W)에 의해 더욱 견고히 결합되고, 종래의 그라우팅재를 주입하여 그라우팅이 경화된 후 인발되는 시 간을 단축하여 네일(N)을 앵커공(A)에 삽입과 동시에 인발이 가능하여 빠른 시공이 가능함은 물론이며, 정확하고 품질이 우수한 시공이 가능한 것이다. 또한 높은 시공 안전성을 가질 수 있는 것이다. Therefore, the compressed air is injected to the fixing blade 120 side through the compressed air injection hole 136 at a high pressure, so that the fixing blade 120 is anchored on the axis of the hinge hole 133 of the fixing blade coupling portion 132. It rotates to the ground side of the ground of (A). The fixing wing 120 rotated in this way pulls the nail N from the outside at the same time that the portion formed at the other acute angle of the fixing wing 120 is fixed to the ground to the ground side of the ground of the anchor hole (A). In this way, the fixing wing 120 is fixed from the outside and at the same time it is more firmly coupled by the wedge member (W) when drawing the nail (N), by injecting a conventional grouting material to shorten the time to be drawn after the grouting is cured (N) is inserted into the anchor hole (A) and at the same time can be drawn out of the fast construction is possible, of course, it is possible to be accurate and excellent construction. In addition, it is possible to have a high construction safety.

한편, 전술한 바와 같이 그라우팅재를 주입하기 전에 네일선단정착구에 의해 네일(N)를 먼저 인발한 후, 그라우팅재를 주입하여 경화시킴으로써, 정착헤드부(130)로부터 확장된 정착날개(120)은 지중의 지면에 더욱 견고히 정착되게 되고 인발에 따른 네일(N)이 앵커공(A)의 축선상에서 수평을 이루게 되어 네일(N)이 뒤틀리어 변형되거나, 자중에 의해 앵커공(A)의 바닥면으로 쳐지게 되어 부식 및 파손, 시공불량 등을 초래하는 등의 문제점이 현저히 감소되게 된다. On the other hand, as described above, before the injection of the grouting material nail (N) by drawing the nail first, and then by fixing the injection grouting material, the fixing blade 120 extended from the fixing head portion 130 is It becomes more firmly fixed to the ground of the ground and the nail (N) according to the drawing becomes horizontal on the axis of the anchor hole (A) so that the nail (N) is twisted or deformed, or the bottom surface of the anchor hole (A) by its own weight As a result, problems such as corrosion and breakage, poor construction, etc. are significantly reduced.

그리고, 본 발명의 네일선단정착구(100)의 다수의 정착날개결합부(132)에 각각 결합된 정착날개(120)는 앵커공(A)의 지중의 지면측으로 정착날개(120)가 확장되도록 압축공기 분사공(136)에서 토출되는 높은 압력의 압축공기의 일정압력 이상에서 정착날개(120)가 정착날개결합부(132)로부터 힌지회동되어 앵커공(A)의 지중의 지면측으로 확장되는 것이 바람직하다. In addition, the fixing blades 120 respectively coupled to the plurality of fixing blade coupling portions 132 of the nail tip fixing fitting 100 of the present invention are compressed so that the fixing blades 120 are expanded to the ground side of the ground of the anchor hole A. Above a certain pressure of the high pressure compressed air discharged from the air injection hole 136, it is preferable that the fixing blade 120 is hinged from the fixing blade coupling portion 132 to extend to the ground side of the ground of the anchor hole A. Do.

즉, 압축공기의 일정압력 이상에서만 힌지회동됨으로써, 통상의 대기압의 압력에서는 정착날개(120)가 네일선단정착구(100)의 다수의 정착날개결합부(132)로부터 확장되지 않고 네일선단정착구(100)의 정착날개결합부(132)에 끼움결합되어 있 는 것이다. 따라서, 네일선단정착구(100)가 선단부에 구비된 네일(N)을 앵커공(A)에 삽입시, 정착날개(120)가 단순한 충격 및 대기압에 의해서 정착날개결합부(132)로부터 힌지회동되어 돌출되지 않아 앵커공(A) 내에 삽입시공이 용이한 것이다. That is, by hinge rotation only at a predetermined pressure or more of the compressed air, the fixing blade 120 does not extend from the plurality of fixing blade coupling portion 132 of the nail tip fixing fixture 100 at the normal atmospheric pressure, nail tip fixing fitting 100 ) Is fitted to the fixing blade coupling portion (132). Accordingly, when the nail tip fixing fitting 100 is inserted into the anchor hole A with the nail N provided at the tip portion, the fixing blade 120 is hinged from the fixing wing coupling portion 132 by a simple impact and atmospheric pressure. It is easy to insert into the anchor hole (A) does not protrude.
