본 발명은 조립식 보강토 옹벽 지지용 띠형 섬유보강재의 시공방법 및 이 시공방법에 사용되는 띠형 섬유보강재에 관한 것으로, 특히 앵커와 앵커 핀 없이 띠 형 섬유보강재의 선단부를 반폭으로 접어 옹벽 블록에 형성된 보강재 삽입홈에 직접 걸어줌으로써 확고한 연결상태를 이루고, 앵커나 앵커 핀과 같은 부자재의 소비를 줄임과 아울러 연결작업의 단순화를 도모할 수 있도록 하며, 보강재 선단부의 느즈러짐이 발생하지 않고 응력이 집중되지 않아 옹벽 면의 시공하자가 발생하지 않고, 보강토체 내에 매립되는 띠형 섬유보강재는 전 폭으로 펼친 상태로 설치되어 보강토체와의 마찰지지력을 발휘하며, 섬유보강재의 후단부는 앞쪽 마찰력에 부가하여 수동지지저항력을 발휘할 수 있도록 한 것이다.The present invention relates to a method of constructing a band-shaped fiber reinforcement for supporting prefabricated reinforcement earth retaining wall, and a band-shaped fiber reinforcement used in the method, and particularly, a reinforcement insert formed in a retaining wall block by folding the tip portion of the band-shaped fiber reinforcement without an anchor and an anchor pin in half width. Direct connection to the groove creates a firm connection, reduces the consumption of subsidiary materials such as anchors and anchor pins, simplifies the connection process, and does not cause loosening of the reinforcement tip and stress concentration. The band-shaped fiber reinforcement embedded in the reinforcement soil is installed in full-stretched state to exert friction support with the reinforcement soil, and the rear end of the fiber reinforcement material is added to the front friction force to provide passive bearing resistance. It was to be able to exercise.

도 10은 옹벽 축조용 블록과 띠형 섬유보강재를 사용하여 축조되는 일반적인 조립식 보강토 옹벽의 축조상태를 도시한 평면도로서, 옹벽의 전면을 이루는 블록(1)을 지지하기 위한 띠형 섬유보강재(2)의 선단부(F)가 앵커(3)와 앵커 핀(4)에 의해 블록(1)과 연결되고 나머지 부분은 보강토체(5)내에 펼쳐진 상태로 매립되는 구조로 이루어져 있다.FIG. 10 is a plan view showing the construction of a general prefabricated reinforcement retaining wall constructed using a retaining wall building block and a strip-shaped fiber reinforcing material, and a tip portion of the strip-shaped fiber reinforcing material 2 for supporting the block 1 forming the front surface of the retaining wall. (F) is connected to the block (1) by the anchor (3) and the anchor pin (4) and the remaining portion is made of a structure that is embedded in the expanded state in the reinforcement soil (5).

한편, 상기한 바와 같은 종래의 띠형 섬유보강재를 사용한 전형적인 조립식 보강토 옹벽에 있어서는 띠형 섬유보강재(2)와 블록(2)을 연결시키기 위한 앵커(3)와 앵커 핀(4)이 매 연결부위마다 설치되어야 했었으므로, 그 수량이 최소한 블록 수량의 수배나 되어 부자재에 대한 소요비용이 큰 부담이 되었을 뿐만 아니라, 이의 연결작업에 있어서도 띠형 섬유보강재(2)의 선단부(F)가 앵커 핀(4)을 감싸면서 연결되므로 이 접히게 되는 부분이 늘어지지 않도록 작은 곡률반경이 되게 팽팽하게 당겨준 후 그 위에 보강토체(5)를 포설하기 전까지 느슨해지지 않고 그대로 당 겨진 상태를 유지할 수 있도록 띠형 섬유보강재(2)의 후단부(R)에 임시고정철근(6)과 고정말뚝(7) 등을 사용하여 고정시켜주어야 했었으므로 추가적으로 부자재가 더 소요되는 문제점이 있었고, 이러한 부자재들은 옹벽의 시공과정에서 보강토체(5)내에 그대로 매립되어 버리므로 재사용이 불가능하여 자원의 낭비는 물론 시공단가도 상승하게 되는 폐단이 있었으며, 상기한 띠형 섬유보강재의 당김 작업은 대부분 여러 사람이 동시에 동원되어야 하는 것일 뿐만 아니라, 띠형 섬유보강재를 손으로 잡고 당기는 작업이 매우 고되고, 보강재를 당긴 상태에서 보강토체 위에 임시고정하기 위한 작업이 비능률적이었으므로 조립식 보강토 옹벽의 시공성 저하요인으로 작용했었다.On the other hand, in the typical prefabricated earth retaining wall using the conventional band-shaped fiber reinforcement as described above, the anchor 3 and anchor pins 4 for connecting the band-shaped fiber reinforcement 2 and the block 2 are installed at every connection part. Since the quantity was at least several times as large as the number of blocks, the cost of the subsidiary materials was not only a big burden, but also in the connection work, the tip portion F of the strip-shaped fiber reinforcement 2 was connected to the anchor pin 4. As it is wrapped and connected, it is pulled tightly to have a small radius of curvature so that the folded portion does not stretch, and then the band-shaped fiber reinforcement (2) can be kept in a pulled state without being loosened until the reinforcement soil (5) is laid thereon. There was a problem that additional subsidiary materials were required because it had to be fixed to the rear end (R) of the temporary fixing bar (6) and the fixing pile (7). These subsidiary materials are buried in the reinforcement soil (5) during the construction of the retaining wall, so they cannot be reused, resulting in waste of resources as well as an increase in construction cost. Not only did people have to be mobilized at the same time, but it was very hard to grasp and pull the band-shaped fiber reinforcement by hand, and the work to temporarily fix it on the reinforcement body while pulling the reinforcement was inefficient, and it acted as a deterioration factor of the constructability of the prefabricated retaining wall.

또한, 종래의 띠형 섬유보강재는 블록과의 연결부위 자체가 상하로의 유동성에 대하여 경직된 구조로 이루어져 있었으므로 시공후 보강토체의 침하에 따른 구조체 즉, 블록으로 이루어진 옹벽 면의 변위가 크게 발생했었고, 섬유보강재의 선단부가 곡률반경이 작게 접혀지게 되어 시공 완료후 여기에 응력이 집중되는 문제점이 있었으며, 블록과 섬유보강재와의 연결부위의 크기나 형태에 따라 각기 다른 형태나 칫수의 연결자재를 사용하여야 했었으므로 부자재의 추가로 인한 시공비용의 부담은 물론 시공능률이 저하되는 문제점이 있었고, 이들 연결자재를 사용할 경우 블록과 보강재와의 연결구조에 대한 안전성을 확보하는데 많은 노력을 기울여야만 했었다.In addition, since the conventional band-shaped fiber reinforcement has a rigid structure for the fluidity of the up and down connection with the block itself, a large displacement of the retaining wall surface of the structure, that is, the block according to the settlement of the reinforcement soil occurred after construction. There was a problem that the tip of the fiber reinforcement has a small radius of curvature and stress is concentrated after the completion of construction, and connection materials of different shapes or dimensions should be used depending on the size and shape of the connection portion between the block and the fiber reinforcement. Therefore, there was a problem that the construction efficiency as well as the burden of the construction cost due to the addition of subsidiary materials, and when using these connecting materials had to make a lot of efforts to secure the safety of the connection structure between the block and the reinforcement.

또한, 종래의 띠형 섬유보강재는 블록의 크기에 비해 상대적으로 폭이 넓어 옹벽 벽체를 구성하는 블록의 크기 및 수량에 비해 섬유보강재의 부설밀도가 낮아 불안정한 구조체를 형성하게 되는 문제점도 있었다.In addition, the conventional strip-shaped fiber reinforcement has a relatively wider width than the size of the block has a problem of forming an unstable structure because the laying density of the fiber reinforcement is low compared to the size and number of blocks constituting the retaining wall wall.

본 출원인은 위와 같은 문제점을 해소하기 위하여 상기한 띠형 섬유보강재를 혼자서도 손쉽고 효율적으로 당겨줄 수 있도록 와이어를 당겨주기 위한 장선기의 원리를 이용한 여러 가지 형태의 보강재 당김기구 및 이러한 당김기구를 사용한 보강재 당김 공법을 개발하여 특허 제302139호, 특허 제404128호 및 실용신안등록 제216353호, 동등록 제21457호, 동등록 제221903호, 동등록 제223133호, 동등록 제314862호 등을 득하여 이들을 실제로 시공현장에 적용하고 있다.In order to solve the above problems, the present applicants pull various types of reinforcing material pulling mechanisms and reinforcing material pulling devices using the principle of the joist to pull the wire so that the above-mentioned fiber-shaped fiber reinforcement can be easily and efficiently pulled alone. Developed the construction method and acquired the patent No. 302139, No. 404128 and Utility Model Registration No. 216353, Registration No. 21457, Registration No. 221903, Registration No. 223133, Registration No. 314862, and actually installed them. It is applied to the field.

그럼에도 불구하고 상기한 바와 같은 기존 조립식 보강토 옹벽의 띠형 섬유보강재 설치구조에 있어서는 보강재의 당김 작업은 보다 수월하고 신속하게 할 수는 있게 되었으나, 앵커와 앵커 핀 및 임시고정철근 등 띠형 섬유보강재를 블록과 연결하고 보강토체의 매립 전까지 당겨진 상태를 유지하기 위한 부자재의 과다소요에 대한 문제점 등이 여전히 지적되고 있으며, 이에 대한 해결책을 본 출원인을 비롯하여 대부분의 조립식 보강토 옹벽 시공관련자들이 다방면으로 오랜 기간동안 강구하고 있으나, 아직까지 뚜렷한 개선안이 개발되어 있지 못한 실정이다.Nevertheless, in the structure of the installation of the band-shaped fiber reinforcement of the existing prefabricated reinforcement retaining wall as described above, pulling of the reinforcement can be performed more easily and quickly, but the band-shaped fiber reinforcement such as anchors, anchor pins and temporary fixing reinforcing bars The problem of excessive demand for subsidiary materials for connecting and maintaining the pulled state before reinforcement of reinforcement is still pointed out. However, no clear improvement has been developed yet.

본 발명은 상기한 종래의 제반 문제점을 해소하기 위하여 안출된 것으로, 본 발명의 목적은 블록과 띠형 섬유보강재를 사용하여 조립식 보강토 옹벽을 축조함에 있어서, 옹벽 축조용 블록을 지지하기 위한 띠형 섬유보강재를 앵커와 앵커 핀 없 이 옹벽 축조용 블록에 직접 연결시키고 보강토체 내에 지그재그상태로 연속설치 또는 개별적으로 설치하여 블록을 견고하게 지지할 수 있고, 옹벽 벽체를 구성하는 블록의 크기 및 수량에 부합될 수 있는 보강재 부설밀도를 가질 수 있는 조립식 보강토 옹벽 지지용 띠형 섬유보강재의 시공방법과 이 시공방법에 적합한 형태의 띠형 섬유보강재를 제공하는데 있다.

본 발명에 의한 띠형 섬유보강재의 시공방법에서는 상기 제1 내지 제7실시 예에만 국한되는 것이 아니며, 옹벽을 이루는 블록의 다양한 형태에 따라 섬유보강재 선단부의 연결부위의 형태나 크기는 바뀔 수 있으며, 섬유보강재의 연결방법이 별도의 부자재를 사용하지 않고 다만 작업자가 현장에서 섬유보강재의 선단부를 길이방향을 따라 반폭으로 접은 상태로 블록의 보강재 삽입홈에 끼워주는 것으로 간단하게 완료되는 것이며, 블록에 연결된 부위의 섬유보강재는 보강재 삽입홈에 밀착된 상태이므로 작업중 이탈될 염려가 없을 뿐만 아니라 종래에서와 같이 짧은 금속재 앵커와 앵커 핀을 사용하여 연결할 때 발생되었던 연결부위(접힘부위)에서의 응력집중 및 보강재의 느즈러짐 현상이 일어나지 않으므로 옹벽의 시공완료후 섬유보강재의 느즈러짐으로 인한 옹벽면의 불규칙적인 돌출현상이 발생하지 않으며, 더욱이 본 발명에서는 블록의 보강재 삽임홈에 끼워진 접힌 부분과 보강토체에 매립되는 펼쳐진 부분과의 경계부위는 보강토체의 침하시 접힌 부분이 펼쳐지거나 펼쳐진 부분이 접혀지게 되면서 응력이 집중되는 것을 방지함과 아울러 보강토체의 침하에 따른 블록 벽체의 집중적인 수직하중에 의한 블록의 파손을 방지할 수 있는 완충대로서의 기능을 발휘하게 된다.In the construction method of the strip-shaped fiber reinforcement according to the present invention is not limited to the first to seventh embodiment, the shape or size of the connecting portion of the fiber reinforcing end portion can be changed according to the various forms of the block forming the retaining wall, the fiber The connection method of the reinforcement is simply done by inserting the reinforcement insert into the reinforcement insertion groove of the block with the worker folding the front end of the fiber reinforcement half length along the longitudinal direction without using any additional materials. Fiber reinforcement of the state is in close contact with the reinforcement insertion groove, so there is no fear of detachment during the work, and stress concentration and reinforcement of the reinforcement at the connection part (folding part) generated when using a short metal anchor and anchor pin as in the prior art Looseness of fiber reinforcement after completion of construction of retaining wall is not occurred Irregular protrusion of the retaining wall due to the load does not occur, and in the present invention, the boundary between the folded portion inserted into the reinforcement insertion groove of the block and the expanded portion embedded in the reinforcement soil is unfolded when the folded portion of the reinforcement soil is unfolded. Or the unfolded portion is folded and prevents stress from being concentrated, and also serves as a buffer to prevent breakage of the block due to intensive vertical load of the block wall due to settlement of the reinforcement soil.

또한, 본 발명에서는 섬유보강재의 후단부에도 별도의 자재를 사용하지 않고도 보강재를 길이방향을 따라 반폭으로 접은 상태 또는 원래의 폭이 되도록 세운 상태로 보강토체 내에 매립시킬 경우 보강재 자체의 마찰력에 부가하여 섬유보강재 후단부위에서 수동저항력이 발생되어 보다 견고하고 안정적인 보강토 옹벽의 축조가 가능하게 된다.In addition, in the present invention, when the reinforcement is folded in half the width of the fiber reinforcement along the longitudinal direction or in the state of standing up to the original width without using a separate material in the rear end of the fiber reinforcement in addition to the friction force of the reinforcement itself Passive resistive force is generated at the rear end of the fiber reinforcement, which makes it possible to build a more stable and stable retaining soil retaining wall.

본 발명은 또, 섬유보강재의 폭이 기존의 띠형 섬유보강재보다 절반 정도밖에 되지 않으므로 이의 운반과 현장에서 시공시 취급이 용이하며, 섬유보강재의 폭이 옹벽 축조용 블록의 크기에 적정하여 섬유보강재의 부설밀도 또한 최적의 상태로 설계할 수 있으므로 최소한의 재료를 사용하여 안정적인 구조를 갖는 블록조립식 보강토 옹벽을 축조할 수 있다.In addition, since the width of the fiber reinforcement is only about half the width of the existing strip-shaped fiber reinforcement, it is easy to transport and handle it in the field, and the width of the fiber reinforcement is appropriate to the size of the retaining wall construction block. The laying density can also be designed in an optimal state, so that it is possible to construct a block-reinforced earth retaining wall having a stable structure using a minimum of materials.

이상 설명한 바와 같이 본 발명에 의한 띠형 섬유보강재의 시공방법에서는 조립식 보강토 옹벽을 이루는 옹벽 블록과의 연결을 별도의 앵커나 앵커핀 등을 사용하지 않으므로 부자재에 대한 추가비용부담이 없이 블록과 띠형 섬유보강재간의 연결작업이 가능하게 되며, 블록에 형성된 보강재 삽입홈에 띠형 섬유보강재의 폭을 절반으로 접은 상태로 직접 끼워져 지지하도록 되어 있어 앵커를 사용하여 띠형 섬유보강재를 연결하고 당겨서 시공할 경우 발생하게 되는 띠형 섬유보강재의 느즈러짐을 완벽하게 해소할 수 있고, 띠형 섬유보강재의 후단부는 보강토체 위에 임시고정못 등으로 손쉽게 고정하거나 보강토체의 영역이 좁은 경우나 보다 견고한 지지력을 발휘할 수 있도록 하기 위해서는 보강재 자체를 접어 세워서 자체가 저항체 기능을 발휘하도록 하거나 또는 별도의 저항체 등을 사용할 수 있으므로 조립식 보강토 옹벽을 지지하기 위한 띠형 섬유보강재의 설치작업성이 향상됨은 물론 자재비 와 인건비를 줄일 수 있어 경제적인 시공이 가능한 등의 유용한 효과를 갖는다.As described above, in the method of constructing the strip-shaped fiber reinforcement according to the present invention, the connection with the retaining wall block constituting the prefabricated reinforcement retaining wall does not use a separate anchor or anchor pin, so that the block and the strip-shaped fiber reinforcement are not added to the subsidiary material. It is possible to connect between them, and the band-type fiber reinforcement is formed when connecting and pulling the band-shaped fiber reinforcement by using the anchor. The loosening of the fiber reinforcement can be completely eliminated, and the rear end of the strip-shaped fiber reinforcement can be easily fixed on the reinforcement soil with temporary fixing nails, or when the area of the reinforcement soil is narrow or to show more solid support, It stands up and shows a resistance function by itself To it, or it reduces the separate resistor, etc., so the available improves the installation operability of the band-like fiber reinforcement for supporting the prefabricated reinforced earth retaining wall, as well as material costs and labor costs have a useful effect, such as a cost-effective installation possible.
