Abstract
본 고안은 그라우팅 수단이 구비된 어스앙카(EARTH ANCHOR)에 관한 것으로, 지하에 진입시킨 앙카를 그라우팅하여 앙카가 유동되지 않고 견고하게 설치될 수 있도록 한 것이다.The present invention relates to an earth anchor (EARTH ANCHOR) is provided with a grouting means, by grouting the anchor entered into the basement so that the anchor can be installed firmly without flowing.
즉, 본 고안은 후단부에 타격부(11)가 구비되고, 중간부의 돌출부(12)에 앙카지지구(20)가 결착되는 연결구(13)를 힌지 결합하여 되는 앙카(10)를 구성함에 있어서, 상기 앙카(10) 몸체에는 배면까지 관통하는 충진제유통구(14)를 구비하고, 앙카지지구(20)는 내부에 충진제유입로(21)가 형성되고 주벽에는 임의 간격으로 충진제유출공(22)이 다수 천공되어 구성된 것이다.In other words, the present invention is provided with a striking portion (11) at the rear end, and in constructing the anchor (10) which hinge-couples the connector (13) to which the anchor support (20) is bound to the projection (12) of the middle portion. In addition, the anchor 10 includes a filler flow opening 14 penetrating up to the rear surface, and the anchor support 20 has a filler inflow passage 21 formed therein and a filler discharge hole 22 at an arbitrary interval in the main wall. ) Is composed of many perforations.
이상과 같이 설치되는 본 고안 앙카는 땅속에 진입후 앙카지지구(20) 자체에 구비된 그라우팅 수단을 이용하여 그라우팅 작업을 할 수 있는 효과가 있고, 그라우팅 작업에 의해 충진된 충진제는 굴착공(H)과 앙카 뒷쪽의 공간부(SP)에 충진됨으로 인하여 앙카(10)와 앙카지지구(20)의 유동공간이 없게 되고, 따라서 앙카의 설치 상태가 지속적으로 견고하게 안정되는 것이다.The present invention is installed as described above has an effect that can be grouted by using the grouting means provided in the anchor support (20) itself after entering the ground, the filler filled by grouting work is excavated hole (H ) And the space portion (SP) at the back of the anchor, there is no flow space of the anchor 10 and the anchor support 20, and thus the installation state of the anchor is continuously and firmly stabilized.
Description
본 고안은 그라우팅 수단이 구비된 어스앙카(EARTH ANCHOR)에 관한 것으로 특히, 지하에 진입시킨 앙카를 그라우팅하여 앙카가 유동되지 않고 견고하게 설치될 수 있도록 함을 목적으로 한다.The present invention relates to an earth anchor (EARTH ANCHOR) equipped with a grouting means, in particular, to grout the anchored in the basement so that the anchor can be installed firmly without flowing.
종래의 어스앙카는 도 1의 예시와 같이 후단에 요입된 타격부(11)를 굴착기의 타격봉으로 타격하여 땅속으로 약 6ｍ 이상 진압시킨 후 연결구(13)에 나착된 지지강봉(20)을 당겨주면 앙카(10) 후단의 타격부(11)는 굴착공(H)의 하부에 박히고, 선단부는 앙카(10)의 연결돌출부(12)와 힌지결합된 연결구(13)에 의해 상부로 이동하여 지지강봉(20)과 대략 'T'자형으로 굴착공(H) 측에 걸려 고정되도록 되어있다.Conventional earth anchors hit the striking portion 11 recessed at the rear end with the striking rod of the excavator as shown in the example of FIG. The striking portion 11 of the rear end of the main surface anchor 10 is lodged in the lower portion of the excavation hole H, and the tip portion is moved upward to be supported by the connector 13 hinged to the connection protrusion 12 of the anchor 10. The steel bar 20 and the 'T' shape is fixed to the hanging hole (H) side.
이와같이 설치된 종래의 앙카는 다음과 같은 문제점이 있다.The conventional anchor installed in this way has the following problems.
앙카(10)는 굴착공(H)내에서 지지강봉(20)으로 당길 때 선단부가 상부로 이동하여 'T'자형으로 될때 그 주위의 흙을 상부로 긁어 올려주므로 앙카(10) 후방에는 공간부(SP)가 형성되고 지지강봉(20)은 굴착시 생긴 굴착공(H)내에 유동되도록 설치 되어있었다.When the anchor 10 is pulled to the support steel bar 20 in the excavation hole (H), the tip portion moves upwards and when it becomes a 'T' shape, it scrapes up the soil around it to the upper portion, so the space portion is located behind the anchor 10. (SP) is formed and the support steel bar 20 was installed to flow in the excavation hole (H) generated during the excavation.
따라서 최초에 설치된 앙카(10)와 지지강봉(20)은 지반에 진동이 생기거나, 충격을 받으면 공간부(SP)와 굴착공(H) 내에서 진퇴되면서 유격이 생겨 지지력이 떨어지는 문제점이 있었다.Therefore, the anchors 10 and the supporting steel rods 20 that were initially installed have problems such as vibrations occurring on the ground, or when the shocks are receded in the space portion SP and the excavation hole H, resulting in a drop in support force.
특히 도로 또는 이와 근접된 속에 설치되는 옹벽을 지지하는 어스앙카는 차량 주행에 의한 진동을 지속적으로 받으면서 최초의 지지력을 잃어가게 되고 따라서 옹벽의 지지력이 취약해지는 문제점이 있었다.In particular, the earth anchor supporting the retaining wall installed in the road or in proximity to the road has a problem in that the bearing capacity of the retaining wall is weakened while losing the initial bearing capacity while continuously receiving vibration caused by the vehicle.
본 고안에서는 이상과 같은 문제점을 해결하기 위하여 앙카는 그 후방에 그라우팅 충진제가 주입되도록 구성하고 앙카를 당겨 주는 앙카 지지구는 충진제를 주입할 수 있는 그라우팅 수단을 구비하여 앙카를 지하에 진입시킨 후 그라우팅 작업에 의해 앙카 배면의 공간부와 진입 굴착공을 메워줌으로써 앙카를 견고하고 안정되게 설치하도록 한 것이다.In the present invention, in order to solve the above problems, the anchor is configured so that the grouting filler is injected into the rear, and the anchor support for pulling the anchor is provided with a grouting means for injecting the filler to grout the anchor after entering the basement. By filling the space portion of the back of the anchor and the excavation hole, the anchor is installed firmly and stably.

이를 첨부된 도면에 의하여 그 구성을 상세히 설명하면 다음과 같다.This configuration will be described in detail with reference to the accompanying drawings.
후단부에 타격부(11)가 구비되고 중간부의 연결돌출부(12)에 앙카지지구가 결착되는 연결구(13)를 힌지 결합하여 되는 앙카(10)를 구성함에 있어서, 상기 앙카(10) 몸체에는 배면까지 관통하는 충진제유통구(14)를 구비하고, 앙카지지구(20)는 내부에 충진제유입로(21)가 형성되고 주벽에는 임의 간격으로 충진제압출공(22)이 다수 천공된 그라우팅 수단이 구비됨을 특징으로 한다.In constructing the anchor 10 which is provided with a striking portion 11 at the rear end and hinge-couples the connector 13 to which the anchor support is attached to the connection protrusion 12 of the middle portion, the anchor 10 has a body The filler flow opening 14 penetrates up to the back surface, and the anchor support 20 has a filler inflow passage 21 formed therein, and a grouting means in which a plurality of filler extrusion holes 22 are perforated at arbitrary intervals in the main wall. Characterized in that it is provided.
본 고안 실시에 있어서 충진제유통구(14)는 도 2의 예시와 같이 앙카 몸체에 구멍을 천공하거나, 도6의 예시와 같이 양측변에 요입부를 개별적으로 실시 하거나 복합적으로 실시할 수 있고, 앙카지지구(20)와 연결구(13)의 결착은 도 2의 예시와 같이 연결구(13)의 나사공(13A) 앙카지지구(20)의 하단 나사부(23)를 나착하거나, 도 6의 예시와같이 연결구(13)를 볼트부(13B)로 형성하고 이에 앙카지지수단(20)의 내면 나사부(24)를 나착하여 실시할 수 있다.In the implementation of the present invention, the filler dispensing hole 14 may be perforated in the anchor body as shown in FIG. Bonding of the earth 20 and the connector 13 is attached to the lower thread 23 of the screw hole 13A anchor support 20 of the connector 13, as shown in the example of Figure 2, or as shown in the example of FIG. The connector 13 can be formed by the bolt portion 13B, and the inner surface screw portion 24 of the anchor support means 20 can be screwed in and carried out.
사용도중 앙카(10)를 지하에 깊이 굴진시킬 때에는 일반적인 나착식 연결관체를 이용하여 또다른 앙카지지구를 길게 연결하여 사용할 수 있다.When the anchor 10 is deeply excavated during use, it can be used by connecting another anchor support for a long time using a general plug-in connector.
본 고안 앙카의 설치방법은 지지하고자하는 대상물(옹벽,철주,기타구조물 등)을 당기고자 하는 방향의 지하에 굴착기의 타격봉(40)으로 앙카(10)의 타격부(11)를 타격하여 지하에 깊숙히 박어준다.The installation method of the present invention anchors the striking portion 11 of the anchor 10 with the striking rod 40 of the excavator in the basement in the direction of pulling the target object (retaining wall, pontoon, other structures, etc.) Deeply instill in.
이때 굴착길이는 약 6ｍ 이상 진입시킨 후 앙카지지구(20)를 당겨 지지력을 점검하고 지지력이 미약하면 적정시지력을 가질때 까지 지하 깊숙히 앙카(10)를 진입시켜 준다.At this time, the excavation length is about 6 m or more after pulling the anchor support (20) to check the bearing capacity, if the support force is weak enough to enter the anchor (10) deep underground until it has a proper power.
이와같이 앙카(10)의 굴착 진입이 끝나면 앙카지지구(20)를 이용하여 충진제를 주입한다.As such, when the excavation entry of the anchor 10 is completed, the filler is injected using the anchor support 20.
이때 주입되는 충진제는 충진제유입로(21)를 따라 들어가면서 그 주위의 충진제유출공(22)을 통해 유출되어 굴착공(T)내에 충진되고 일부는 앙카(10)의 충진제유통공(14)을 통해 앙카(10) 뒷쪽의 공간부(SP)에 충진된다.At this time, the filler is injected along the filler inlet 21 and flows out through the filler outlet 22 around the filling is filled in the excavation hole (T) and a part of the filler through the hole 14 of the anchor (10) It is filled in the space SP behind the anchor 10.
충진된 충진제(30)는 양생하여 앙카설치를 완료한다.Filled filler 30 is cured to complete the installation of the anchor.
이상과 같이 설치되는 본 고안 앙카는 땅속에 진입후 앙카지지구(20) 자체에 구비된 그라우팅 수단을 이용하여 그라우팅 작업을 할 수 있는 효과가 있고, 그라우팅 작업에 의해 충진된 충진제는 굴착공(H)과 앙카 뒷쪽의 공간부(SP)에 충진됨으로 인하여 앙카(10)와 앙카지지구(20)의 유동공간이 없게 되고, 따라서 앙카의 설치 상태가 지속적으로 견고하게 안정되는 효과가 있다.The present invention is installed as described above has an effect that can be grouted by using the grouting means provided in the anchor support (20) itself after entering the ground, the filler filled by grouting work is excavated hole (H ) And the space portion (SP) at the back of the anchor, there is no flow space of the anchor 10 and the anchor support 20, and thus the installation state of the anchor is continuously and firmly stable.
