본 발명은 농로의 벽면을 형성하는 벽면블록 및 그 시공방법에 관한 것으로서, 상세하게는 논과 논사이 또는 밭과 밭 사이의 농로를 도로포장 할 때에 좁은 농로의 경사면을 최대한 이용하여 도로의 폭을 최대로 확보하며, 양측 경사면이 비나 외부환경에 의하여 유실되어 포장된 면이 파손되는 것을 방지할 수 있는 벽면블록 및 이를 이용한 농로의 시공방법에 관한 것이다.The present invention relates to a wall block forming a wall of a farm road and a construction method thereof, and more particularly, to maximize the width of a road by maximizing the slope of a narrow farm road when paving roads between rice fields and rice fields or between fields and fields. It is secured to, and both sides of the slope is lost due to rain or external environment to prevent the surface of the pavement is damaged and the construction method of the farm using the same.

일반적으로 논과논 또는 밭과 밭 사이에 형성되는 농로는 논과 논 사이에 약 1m이내의 높이로 형성되는 것이 일반적이며, 농로의 상부를 시멘트나 콘크리트를 타설하여 농기계나 사람이 이동하기 수월하도록 형성한다.Generally, farms formed between paddy fields or paddy fields and fields are generally formed with a height of about 1m between paddy fields and paddy fields. The top of the farm road is formed with cement or concrete to facilitate the movement of agricultural machinery or people. .

그러나, 상기의 농로는 도 1a에 도시한 바와 같이 비나 눈등의 의하여 경사면(1a)이 유실되어 농로(1) 상부의 포장면(1b) 양측이 뜨게 되어 농자재의 바퀴나 사람이 자주 밝음으로써 훼손되는 문제가 많이 발생된다.However, as shown in FIG. 1A, the inclined surface 1a is lost due to rain or snow, so that both sides of the pavement surface 1b on the top of the farm 1 are floated. Many problems arise.

이러한 문제의 대안으로 도 1b에 도시한 바와 같이 포장면의 양측에 거푸집을 이용하여 기둥(2a)을 형성하고 그 내부에 포장면(2b)을 형성하여농로(2)를 시공하고 있다.As an alternative to this problem, as illustrated in FIG. 1B, pillars 2a are formed on both sides of the pavement surface by using formwork, and pavement 2b is formed inside the pavement 2.

그러나, 상기와 같이 포장면(2b)의 양측에 거푸집을 이용하여 기둥(2a)을 형성하는 시공방법은 작업의 공간을 많이 차지하는 문제가 있고, 이러한 문제는 논과 밭등의 개인 사유지를 일부 침범하게 되어 이에 따르는 보상문제등과 같은 복잡한 문제들이 발생되었다.However, the construction method of forming the pillar (2a) by using the formwork on both sides of the pavement surface (2b) as described above takes a lot of work space, this problem is partly invaded private private land such as rice fields and fields This leads to complex problems such as compensation problems.

또한, 작업자가 시공시에 시공을 단순화 하기 위하여 거푸집을 사용하지 않고 콘크리트를 타설함으로써 콘크리트 의 사용량이 많이 들고 외관상 보기가 좋지않은 문제점이 있다.In addition, since the worker casts concrete without using formwork in order to simplify the construction, there is a problem in that the amount of concrete used is high and the appearance is not good.

본 발명의 상기와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 농로의 양측 경사면에 블록을 설치하고 농로포장을 시행함으로써 적은 공간을 최대한 이용하여 농로폭을 최대한 넓게 확보할 수 있으며, 공장에서 생산된 블록을 조립식으로 연결하여 시공함으로써 종래의 거푸집을 이용한 불규칙한 포장선형을 설계된 선형대로 올바르게 시공할 수 있어 외간상 으로도 뛰어나고, 공기또한 단축할 수 있으며, 시공상에서 작업자가 현장관리감독이 소홀할 경우 와이어매쉬를 설치하는 작업을 하지 않고 그냥 콘크리트를 타설하는등의 문제점을 기성화된 블록을 이용하여 시공함으로써 이를 방지할 수 있는 농로의 벽면을 형성하는 벽면블록 및 그 시공방법을 제공하는데 있다. In order to solve the above problems of the present invention, an object of the present invention is to install the blocks on both sides of the farm road and to carry out the farm road packaging to maximize the width of the farm road by using the small space as possible, in the factory By connecting the produced blocks in a prefabricated manner, the irregular paving linear using the conventional formwork can be correctly constructed according to the designed linear shape, so it is excellent in appearance and shortens the air. The present invention provides a wall block and a construction method for forming a wall of a farm road that can prevent the problem of installing concrete using a ready-made block without installing a wire mesh.

이하, 첨부된 도면을 참조하여 본 발명에 따른 농로의 벽면을 형성하는 벽면블록의 구성을 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the wall block forming the wall surface of the farm in accordance with the present invention.

도 2은 본 발명에 따른 농로의 벽면을 형성하는 벽면블록의 사시도이고, 도 3은 본 발명에 따른 농로의 벽면을 형성하는 벽면블록의 종 단면도이며, 도 4는 본 발명에 따른 농로의 벽면을 형성하는 벽면블록이 농로에 시공된 상태의 단면도이다.2 is a perspective view of a wall block forming a wall of the farm according to the present invention, Figure 3 is a longitudinal cross-sectional view of the wall block forming a wall of the farm according to the present invention, Figure 4 is a wall surface of the farm according to the present invention It is sectional drawing of the wall block to form to be constructed in the farm.

도시된 바와 같이 본 발명에 따른 벽면블록(100)은 "L"형으로 형성되며 내부전체에 형성된 철근(11)이 일측면에 노출된 상태로 내장되고 타측면에 이웃하는 블록의 철근이 삽입되는 여러개의 구멍(미도시)이 형성되며 상부면에 여러 개의 삽입공(12)이 형성된 몸체(10)와, 상기 몸체(10)의 내부면에 일부가 돌출되게 형성된 앙카볼트(20)로 이루어진다.As shown, the wall block 100 according to the present invention is formed in an “L” shape, and the reinforcing bar 11 formed in the whole interior is built in the state exposed to one side and the reinforcing bar of the block adjacent to the other side is inserted. A plurality of holes (not shown) are formed and consists of a body 10 having a plurality of insertion holes 12 formed on an upper surface thereof, and an anchor bolt 20 formed by protruding a portion of the inner surface of the body 10.

이와 같이 구성되는 본 발명의 벽면블록(100)은 농로의 양측 경사면을 일정깊이 로 터파기한 후 이 부분에 한쌍의 블록(100, 100')을 안착시키는데 이때, 각각의 블록은 "L"자 형상의 몸체(10, 10')가 마주보는 상태 즉, 내부면의 DDIZKQHFXM(20)가 맞대응되게 안착된다.The wall block 100 of the present invention configured as described above is to dig a predetermined depth of both sides of the farm road to a pair of blocks (100, 100 ') in this portion, each block is "L" shaped DDIZKQHFXM (20) of the inner surface of the body (10, 10 ') facing the opposite state is seated correspondingly.

또한, 상기 블록(100, 100')은 일측에 돌출된 철근(11. 11')이 이웃하는 블록의 타측에 형성된 구멍(미도시)에 삽입되어 연결함으로써 계속하여 연결할 수 있다.In addition, the blocks 100 and 100 'may be continuously connected by inserting and connecting the reinforcing bars 11.11' into one of the holes (not shown) formed on the other side of the neighboring block.

또한, 상기 블록(100)의 높이는 통상적으로 농로의 높이가 밭이나 논의 지면으로부터 1미터 이내의 높이로 형성되기 때문에 1m20cm를 넘지 않게 형성하는 것이 바람직하다.In addition, the height of the block 100 is typically formed so as not to exceed 1m20cm because the height of the farm road is formed to a height within 1 meter from the field or paddy field.

또한, 농로가 곡선으로 형성되있을 경우 길이를 짧게 형성한 블록을 이용하여 원활하게 작업할 수 있다. In addition, when the farm is formed in a curved line, it is possible to work smoothly using a block having a short length.

상기와 같이 블록을 안착시킨 후 블록 내부측과 외부측 하부를 흙으로 매우 고 다지는 작업을 하고 내측 상부에 새골재 또는 석분재등으로 보조기층(30)을 형성하고 그 상부에 습기방지를 위한 필름(31)을 도포한다.After the block is seated as described above, the inner and outer bottoms of the block are very compacted with soil, and the auxiliary base layer 30 is formed on the inner upper part with new aggregate or stone ash, and the film for preventing moisture on the upper part. (31) is applied.

상기와 같이 적층된 상태에서 블록(100, 100')의 내측면에 형성된 앙카볼트(20)의 높이까지 1차로 콘크리트(40)를 타설한 후 와이어매쉬(50)를 안착시키고 양측의 돌출된 앙카볼트(20) 부분과 연결한 후 그 위에 2차 콘크리트(60)를 타설하여 완성한다.After the concrete 40 is poured into the height of the anchor bolt 20 formed on the inner surfaces of the blocks 100 and 100 'in the stacked state as described above, the wire mesh 50 is seated and the protruded anchors on both sides. After the connection with the bolt 20, the secondary concrete 60 is poured on it to complete.

여기서, 상기 블록의 어느한 부분에 구멍을 형성하여 블록 내부의 수분이나 빗물등을 외부로 배출할 수 있다.Here, a hole may be formed in any part of the block to discharge moisture or rainwater inside the block to the outside.

한편, 도 5에는 본 발명에 따른 농로의 벽면을 형성하는 벽면블록의 다른 실시예를 이용하여 농로를 시공한 상태가 도시되어 있다.On the other hand, Figure 5 shows a state in which the construction of the farm using another embodiment of the wall block forming the wall of the farm according to the present invention.

이는 시공방법이나 블록의 구성은 앞에서 설명한 블록과 동일하나 장마기간과 같이 많은 비가 내릴 경우 이 빗물이 양옆으로 흘러내려 논이나 밭으로 유입되는 것을 방지하고 블록 외부측의 흙이 쓸려 내려가는 것을 보호하기 위하여 블록(100)의 상부에 형성된 여러개의 삽입공(12)에 난간(70)에 형성된 철근(71)을 삽입하여 연결함으로써 농로의 상부를 수로 형상으로 변형시켜 사용함으로써 농로 상부의 빗물을 정해진 위치로 이동시켜 배수한다. The construction method and block structure is same as the above-described block, but in case of heavy rain like rainy season, the rainwater flows to both sides and prevents from entering the rice fields or fields, and to protect the soil outside the block from being washed away. By inserting and connecting the reinforcement 71 formed in the handrail 70 to the plurality of insertion holes 12 formed in the upper portion of the block 100, the rainwater on the upper portion of the farm road to a predetermined position is used by transforming the top of the farm road into a water channel shape. Move to drain.

상기 농로의 벽면을 형성하는 벽면블록을 이용한 시공방법을 단계별로 설명하면 다음과 같다.The construction method using the wall block forming the wall of the farm road will be described step by step.
