Description

절토사면의 블럭식 수동보강방법{PASSIVE REINFORCED NAIL WALL FOR CUTTING SLOPE}Block Reinforcement Method of Cut Slope {PASSIVE REINFORCED NAIL WALL FOR CUTTING SLOPE}

본 발명은 절토사면의 블럭식 수동보강방법에 관한 것이다.The present invention relates to a block type manual reinforcement method of cut slope.

더욱 구체적으로는, 종래보다 경제적이면서 또한 신속하게 절토사면을 보강할 수 있는 방법에 관한 것이다.More specifically, the present invention relates to a method that can reinforce cut slopes more economically and quickly than conventionally.

일반적으로, 강안이나 호안, 또는 구릉을 깎아 평탄하게 조성한 부지(아파트단지 등)나 도로를 시공하는 지역에는, 대부분 절토사면(切土斜面)이 존재한다.In general, cut slopes exist mostly in rivers, lakes, or hills and flats (apartment complexes) or roads where roads are constructed.

이러한 절토사면은 인공적인 절토작업에 의해 형성되기 때문에, 사면이 균형을 잃어 위험하며, 또한 토사의 응집력이 약하기 때문에, 비가 많이 내리거나 하면 쉽게 부서져 내려 사태를 일으키게 됨으로, 상기의 사면 둘레로 옹벽을 구축하여 토사 등이 유실되거나 사태가 발생되는 것을 방지한다.Since the cut slope is formed by artificial cutting work, the slope is unbalanced and dangerous, and because the cohesiveness of the soil is weak, it is easily broken when it rains or causes a situation, so that the retaining wall is formed around the slope. To prevent the loss of earth and sand or other situations.

그 동안 사면(또는 경사면)을 보강하기 위한 방안으로서, 국내에서는 철근콘크리트 옹벽이 많이 이용되어 왔는데, 상기 철근콘크리트 구조물의 성형 및 양생에 막대한 비용과 시간이 소모될 뿐만 아니라 굴토작업과 성토작업에 막대한 공사비가 소요되며, 또한 대규모 절토작업에 대한 제약이 많다는 단점이 있어, 약 15년전부터는 앵커볼트가 일체로 된 구조물을 조적하면서 앵커볼트부위에 흙을 매립하여 옹벽을 축조하는 기술이 일본에서 도입되어 시행되고 있다.In the meantime, as a plan for reinforcing slopes (or slopes), reinforced concrete retaining walls have been widely used in Korea, which not only consumes huge costs and time for forming and curing the reinforced concrete structures, but also enormously for pit work and fill work. The construction cost is high, and there are many limitations for large-scale cutting work. Since about 15 years ago, the technology to build the retaining wall by embedding soil in the anchor bolt area while constructing the structure with the anchor bolts integrated was introduced in Japan. It is implemented.

그러나, 이 보강방법도 굴토 및 성토작업에 많은 비용이 소모되고, 또한 전체적으로 구조물이 커지게 되는 단점이 있었다.However, this reinforcement method also has a disadvantage in that a large amount of cost is consumed in gulting and filling work, and the structure as a whole becomes large.

첨부도면중 도3은 이러한 문제를 개선하기 위해 제안된 종래의 예를 나타낸 단면도로서(국내특허공보 제1993-629호), 옹벽을 구성하기 위한 바닥면부까지 소정 각도로 사면(6)이 형성되게 절토를 한 다음, 그 사면(6)의 최하단부에 일정 간격을 두고 옹벽면과 거의 수직하게 수평방향으로 앵커구멍(11)을 굴착하고, 상기 앵커구멍의 중심부에 지중볼트(21)를 삽입한 후 상기 앵커구멍에 몰탈 등을 채워넣어 양생시키고, 상기 지중볼트의 말단나사부에 지압판(20)을 끼워 너트(24)를 체결하며, 상기 지압판과 사면 사이의 공간부에 토사를 채워넣어 성토층을 형성하고, 다시 상기 너트를 조여서 성토층에는 압축응력이, 반대로 지중볼트에는 인장응력이 작용되도록 하여 사면(斜面)을 보강하였다.3 is a cross-sectional view showing a conventional example proposed to improve such a problem (Domestic Patent Publication No. 1993-629), wherein the slope 6 is formed at a predetermined angle up to the bottom surface portion for forming the retaining wall. After cutting, the anchor hole 11 is excavated in a horizontal direction substantially perpendicular to the retaining wall surface at regular intervals at the lowermost end of the slope 6, and the underground bolt 21 is inserted into the center of the anchor hole. The anchor hole is filled with mortar and cured, and the nut 24 is fastened by inserting the pressure plate 20 into the end screw portion of the underground bolt, and filling the soil in the space between the pressure plate and the slope to form a fill layer. In addition, the nut was tightened to reinforce the slope by compressing stress to the fill layer and tensile stress to the ground bolt.

그러나, 상기 특허기술은, 수 십ton의 초기 인장력을 가하기 위해서 대형 콘크리트 패널을 지압판으로 사용하기 때문에, 콘크리트 패널의 운반 및 시공이 용이하지 않다는 단점이 있고, 또한 사면의 최하부측이 굴곡져 있는 경우, 대형 콘크리트 패널로는 사면 하부의 굴곡(윤곽)에 맞춰 시공할 수 없어, 사면과 지압판 사이가 불필요하게 넓어지는 문제점이 있었다.However, the patented technology has a disadvantage in that it is not easy to transport and construct the concrete panel because a large concrete panel is used as a pressure plate to apply an initial tensile force of tens of tons, and when the lowermost side of the slope is curved. , The large concrete panel can not be constructed in accordance with the bend (contour) of the lower slope, there was a problem that the space between the slope and the pressure plate unnecessarily wide.

이처럼 사면과 지압판 사이가 넓은 경우, 그 사이에 채워넣어야 하는 토사량이 많아지는 것은 물론 개개의 패널에 불균일하게 토압이 작용되어 내구성에 문제가 생긴다.If the slope and the pressure plate is wide in this way, not only the amount of soil to be filled in between, but also the earth pressure is applied to the individual panels unevenly, causing durability problems.

첨부도면중 도4는, 종래 블럭을 이용한 사면의 보강방법을 설명하기 위해 나타낸 도면이다.Figure 4 of the accompanying drawings is a view showing for explaining a method of reinforcing the slope using a conventional block.

상기 보강방법은, 지면 위로 겹겹이 쌓아 올린 블럭(1a)의 구조체와 사면(경사면)(6) 사이에, 현장에서 쉽게 구할 수 있는 유용토(토사)나 숏크리트 등을 뒷채움재로 채워 넣되, 매 일정 높이(깊이)마다 지오그리드나 배근체를 삽설하여, 지층 약화에 따른 여러가지 문제-예컨대, 지층의 유실-을 예방할 수 있게 한 것이 특징이다.The reinforcement method is to fill in between the structure of the block (1a) and the slope (slope) (6) stacked on the ground with a backfill material useful soil (soil) or shotcrete, which can be easily obtained in the field, Geogrids or reinforcement bodies are inserted at each height to prevent various problems due to the weakening of the layers, such as loss of the layers.

그런데, 상기의 보강방법은 성토사면에 대해서만 한정적으로 이용할 수 있을 뿐이었다.By the way, the above reinforcement method could only be used only on the fill slope.

본 발명은 이러한 종래의 단점을 개선하기 위해 안출된 것으로서, 블럭으로 절토사면의 보강공사를 실시함으로서 절토사면의 안정성을 신속하게 경제적으로 확보할 수 있게 하여, 종래의 절토사면 보강방법이 갖고 있던 문제점을 개선함과 동시에 충분히 토압에 견딜 수 있는 절토사면의 블럭식 수동보강방법을 제안함에 목적이 있다.The present invention has been made to improve such a conventional disadvantage, by performing the reinforcement of the cut slope with a block to quickly and economically ensure the stability of the cut slope, a problem that the conventional cut slope reinforcement method had The purpose of this study is to propose a block type manual reinforcement method of cut slope that can withstand the earth pressure.

또한, 본 발명은, 대형 콘크리트 패널을 이용하는 경우보다, 경제적이면서도 신속하게 시공할 수 있는 방법을 제공함에 목적이 있다.In addition, an object of the present invention is to provide a method that can be economically and quickly construction than when using a large concrete panel.

첨부도면중 도1과 도2는, 각각 본 발명에 따른 사면의 보강방법을 설명하기 위해 도시한, 시공 상태도와 확대 사시도이다.1 and 2 of the accompanying drawings are construction state diagrams and enlarged perspective views, respectively, for explaining the method of reinforcing the slope according to the present invention.

상기의 도면에서 참조되는 바와 같이, 본 발명에서는,As referred to in the above drawings, in the present invention,

먼저, 상단부로부터 일정한 깊이만큼 절토를 한 다음, 그 절토된 사면(6)에 록커(5)로 네일링하고,First, cut to a certain depth from the upper end, then nailed to the cut slope 6 with a rocker 5,

원하는 깊이(또는, 높이)까지 절토가 된 후에는, 절토부위의 최하측에 보강용 블럭(1,1a)을 쌓기 위해, 사면에서 일정한 거리를 두고 최하부측 윤곽을 따라 터파기를 하고,After cutting to the desired depth (or height), in order to lay the reinforcing blocks (1, 1a) on the lowermost side of the cut area, they are excavated along the lowermost contour at a certain distance from the slope,

그 후, 그 곳에 기초 콘크리트를 포설하여 층층이 블럭(1,1a)을 쌓아 올리되, 일정한 간격마다-예컨대, 상하 및 좌우 1.5m 간격마다-보강판(2)이 끼움홈(3)에 삽착된 블럭(1)을 배설하여, 그 보강판(2)에 상기의 록커(5)를 너트로 지지시키고,Thereafter, the foundation concrete is laid there, and the layers are stacked up with blocks 1, 1a, and the reinforcing plates 2 are inserted into the fitting grooves 3 at regular intervals, for example, at intervals of up and down and left and right 1.5 m. The block 1 is disposed, and the locker 5 is supported on the reinforcement plate 2 with a nut,

이후, 상기의 과정을 반복하여, 원하는 높이의 구조물을 사면 둘레에 형성함으로서 완료된다.Thereafter, by repeating the above process, by forming a structure of the desired height around the slope is completed.

한편, 본 발명에서와 같이, 블럭(1)에 보강판(2)을 삽착하여 록커(5)를 고정시키게 되면, 주변의 다른 블럭(1a)으로 토압이 분산되는 효과가 있어 큰 토압도 지탱할 수 있다는 장점이 있다.On the other hand, as in the present invention, when the locker 5 is fixed by inserting the reinforcement plate 2 into the block 1, the earth pressure is distributed to other blocks 1a in the periphery, so that a large earth pressure can be supported. There is an advantage.

뿐만 아니라, 본 발명에서와 같이 블럭을 사용하는 경우, 대형 콘크리트 패널을 이용할 때 보다 구성재료의 운반과 취급이 용이하고, 시공이 수월해지는 장점이 있으며, 시공속도도 빨라지는 이점이 있다.In addition, in the case of using the block as in the present invention, when using a large concrete panel, there is an advantage that it is easy to transport and handle the constituent materials, the construction is easier, and the construction speed is also faster.

이상과 같이 하여, 블럭(1,1a)과 보강판(2)의 구조물이 완성되면, 상기 구조물과 절토사면(6) 사이의 빈 공간에, 작업현장에서 쉽게 구할 수 있는 유용토(토사)를 채워 다지거나 숏크리트(4)를 타설하여 옹벽을 안정시킨다.As described above, when the structures of the blocks 1, 1a and the reinforcement plate 2 are completed, useful soils (soils) which can be easily obtained at the work site are placed in the empty space between the structures and the cut slopes 6. The retaining wall is stabilized by filling or pouring shotcrete 4.

이상과 같이, 본 발명에 따른 절토사면의 블럭식 수동보강방법에 의하면, 숙련되지 못한 작업자도 작업실시가 가능하다는 장점이 있고, 또한 구성재료의 운반 및 취급이 수월한 이점이 있으며, 크기가 작은 블럭들을 이용함으로서 절토사면의 하부측 윤곽에 맞춰 구조물을 구축할 수 있어 외관상 보기 좋으며, 특히 절토사면과 구조물 사이의 간격을 최소화시켜 뒷채움재를 적게 쓸 수 있도록 함으로서 경제적이고, 특히 시공속도가 빠르다는 장점이 있다.As described above, according to the block-type manual reinforcement method of the cut slope according to the present invention, there is an advantage that even an inexperienced worker can carry out the work, and also has the advantage of easy transportation and handling of the material, small block size The structure can be constructed according to the lower side contour of the cut slope by using them, and it is good in appearance. Especially, it is economical by minimizing the gap between the cut slope and the structure so that the backfill can be used less, and the construction speed is particularly fast. There is this.
