Description
본 고안은 흙막이벽을 지지하는 그라운드 앵커에 관한 것으로, 더욱 상세하게는 그라운드 앵커를 개량하여 지중에서 그라운드 앵커가 보다 큰 응력을 발휘할 수 있게 하여 흙막이벽을 보다 견고하게 지지할 수 한 그라운드 앵커에 관한 것이다.The present invention relates to a ground anchor that supports the retaining wall, and more particularly, to a ground anchor that can support the retaining wall more firmly by improving the ground anchor to exert a greater stress in the ground. will be.
일반적으로 고층건물이나 지하철 또는 기타 대형구조물의 지하구조물을 건설할 때에는 지하로 깊이를 더해가면서 주변에 H빔을 수직으로 고정하고 대형의 괴목을 이용하여 흙막이벽을 형성하게 된다. 이 경우에 횡으로 설치된 괴목이 받는 주위의 토압은 지하로 들어감에 따라 수백톤에 이르는 압력을 받게 되어 결국 흙막이벽이 압력을 이기지 못하고 붕괴하는 사고가 발생하게 된다.In general, when constructing high-rise buildings, underground structures of subways or other large structures, H-beams are fixed vertically while adding depth to the basement, and a large wall is used to form an earthen wall. In this case, the earth pressure around the lateral trees is pushed up to several hundred tons as it enters the basement, resulting in the collapse of the wall without overcoming the pressure.
이에 흙막이벽의 붕괴를 막기 위해 대형 빔을 이용으로 지하공간 양측의 흙막이벽을 연결하는 강제 보강공법을 실시하기도 하지만 이와 같은 경우 격자로 설치된 강철제 빔이 원활한 시공을 방해하는 장애요소가 되어 작업능률 저하와 공사기간 연장, 공사비용 상승 및, 막대한 철재 낭비등의 여러가지 문제를 야기시키게 된다.In order to prevent the collapse of the retaining wall, a forced beam reinforcement method is used to connect the retaining walls of both sides of the underground space with a large beam. However, in this case, the steel beam installed as a grid is an obstacle to smooth construction. It causes many problems such as deterioration, extension of construction period, rising construction cost, and huge waste of steel.
이러한 문제점을 해결하기 위하여 흙막이벽의 이면 지중에 구멍을 형성시키고, 이에 강선이 연결된 앵커를 삽입시킨 후 구멍의 내부로 콘크리트를 주입 양생시켜 강선이 흙막이벽을 지지할 수 있게 하는 시공방법이 널리 이용되고 있다.In order to solve this problem, a construction method for forming a hole in the back ground of the retaining wall, inserting an anchor connected to the steel wire, and injecting and curing concrete into the hole allows the steel wire to support the retaining wall. It is becoming.
첨부된 도면 도 1 은 일반적인 그라운드 앵커의 시공 실시 예를 도시한 단면도이다.1 is a cross-sectional view showing a construction example of a general ground anchor.
도 1 에서와 같이, 흙막이벽(100)의 이면 지중에 구멍(200)을 형성시키고, 구멍(200)의 내부로 강선(3)이 연결된 앵커본체(1)를 삽입시킨 다음 구멍(200)의 내부로 콘크리트(300)를 주입시켜 양생시킨다.As shown in FIG. 1, a hole 200 is formed in the bottom surface of the retaining wall 100, the anchor body 1 connected with the steel wire 3 is inserted into the hole 200, and then the hole 200 is formed. Inject the concrete 300 into the interior to cure.
주입된 콘크리트(300)의 양생이 완료되면 흙막이벽(100)의 외부로 노출된 강선(3)을 인장시키고 이를 앵커헤드(4)에 고정시킴으로서 흙막이벽(100)이 흙의 압력에 대항 할 수 있는 것이다.When curing of the injected concrete 300 is completed, the barrier wall 100 can counteract the pressure of the soil by tensioning the steel wire 3 exposed to the outside of the barrier wall 100 and fixing it to the anchor head 4. It is.
첨부된 도면 도 2 는 종래의 그라운드 앵커를 도시한 단면도이다.2 is a cross-sectional view showing a conventional ground anchor.
도 2에서 보는 바와 같이 종래에 있어서의 그라운드 앵커는 강선(3)의 일단이 물리어 고정되는 앵커본체(1)와; 앵커본체(1)의 선단에 설치되는 내하체(2)와; 강선(3)의 외부에 감싸여 설치되는 피복(30)과; 강선(3)의 또 다른 단부가 결합되는 앵커헤드(4)로 구성된다.As shown in Fig. 2, the ground anchor in the prior art includes: an anchor body 1 in which one end of the steel wire 3 is bitten and fixed; A lower body 2 installed at the tip of the anchor body 1; A cover 30 wrapped around the outside of the steel wire 3 and installed; It consists of an anchor head 4 to which another end of the steel wire 3 is coupled.
상기 내하체(2)는 주물로 제작되며 구멍(200)에 주입되는 콘크리트(300)와 결합되어 강선(3)의 인장력으로 당겨지는 앵커분체(1)를 지지하는 역할을 한다.The load-bearing body 2 is made of a casting and is coupled to the concrete 300 is injected into the hole 200 serves to support the anchor powder (1) pulled by the tensile force of the steel wire (3).
그라운드 앵커가 본래의 기능을 충분하게 발휘할 수 있으려면 인장력에 대항하는 응력이 커야되고 보다 넓게 분포되어야 한다.In order for the ground anchor to be able to fully function its original function, the stress against the tensile force must be large and distributed more widely.
그러나 종래의 그라운트 앵커는 인장력에 대항하는 응력이 내하체(2)와 앵커분체(1)의 주변에만 집중되어 응력이 넓은 범위에 분포되지 못함에 따라 인장력이 응력을 한계를 넘어서면 내하체(2)의 주변에서 콘크리트(300)가 파열되는 문제점이있다.However, the conventional ground anchors are concentrated only in the periphery of the load bearing body 2 and the anchor powder 1 because the stress against the tensile force is not distributed over a wide range, and thus the tensile load exceeds the load when the tensile force exceeds the limit. There is a problem that the concrete 300 is ruptured in the vicinity of 2).
이는 강선(3)이 피복(30)에 의해 가려져 콘크리트(300)와 결합되지 못하고, 피폭(30)은 합성수지재질로 형성되어 콘크리트(300)와의 결합력이 매우 취약하기 때문이다.This is because the steel wire (3) is covered by the coating 30 is not coupled with the concrete 300, the exposure 30 is formed of a synthetic resin material is very weak bonding force with the concrete (300).
이와 같이 콘크리트(300)가 파열되면 인장력에 대한 응력이 감소됨은 물론 파열된 틈새로 수분이 침투되어 앵커본체(1)와 강선(3)을 부식시키고 결국에는 응력이 상실되어 그라운드 앵커로의 기능이 상실되는 문제점이 있다.As such, when the concrete 300 is ruptured, the stress on the tensile force is reduced, as well as moisture penetrates into the ruptured gap to corrode the anchor body 1 and the steel wire 3, and eventually the stress is lost to function as a ground anchor. There is a problem that is lost.
본 고안은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 본 고안은 그라운드 앵커를 개량하여 지중에서 큰 응력을 발휘하게 함은 물론 보다 넓은 범위에서 응력이 분포되게 하여 흙막이벽을 보다 견고하게 지지할 수 한 그라운드 앵커를 제공함에 그 목적이 있다.The present invention is to solve the conventional problems as described above, the present invention is to improve the ground anchor to exert a large stress in the ground as well as to distribute the stress in a wider range to support the earth wall more firmly The purpose is to provide as many ground anchors.
본 고안은 상기와 같은 목적을 달성하기 위하여 다음과 같이 구성된다. 즉, 본 고안은 강선의 일단이 물리어 고정되는 앵커본체와; 앵커본체의 선단에 설치되는 내하체와; 강선의 외부에 감싸여 설치되는 피복과; 강선의 또 다른 단부가 결합되는 앵커헤드로 구성되는 것에 있어서, 상기 강선의 피복 외측에 보강파이프를 설치시켜 구성되는 것에 특징을 둔 것이다.The present invention is configured as follows to achieve the above object.
