조립식 콘크리트 옹벽 및 그의 시공방법{Prefabricated retaining wall and it's construction method} Prefabricated retaining wall and it's construction method

본 발명은 조립식 콘크리트 옹벽 및 그의 시공방법에 관한 것으로, 특히 옹벽을 구축하기 위한 부지가 좁고, 옹벽의 설치가 어려운 경우에서도 손쉽게 시공할 수 있으며, 옹벽 구축시의 굴토나 성토 등의 토공량을 큰 폭으로 삭감시킬 수 있을 뿐만 아니라 옹벽에 사용되는 재료도 저감시킬 수 있도록 한 조립식 콘크리트 옹벽 및 그의 시공방법에 관한 것이다.The present invention relates to a prefabricated concrete retaining wall and its construction method, and in particular, it is easy to construct even when the retaining wall is narrow and the installation of the retaining wall is difficult. The present invention relates to a prefabricated concrete retaining wall and a method for constructing the same, which can be reduced as well as the material used for the retaining wall.

일반적으로 콘크리트 옹벽은 수직으로 연장되는 전면벽체에 대해, 거의 직각 방향으로 연장하는 바닥판으로 이루어지며, 수평한 기초부상에 지지된 상태로 설치된다.In general, the concrete retaining wall is composed of a bottom plate extending in a substantially perpendicular direction with respect to the front wall extending vertically, is installed in a state supported on a horizontal foundation.

그렇지만, 상기한 바와 같이 거의 90°인 직각 콘크리트 옹벽에 있어서, 충분한 활동저항을 얻음과 동시에 콘크리트 옹벽이 매입 깊이에 관한 규정치를 명확히 하기 위해서, 콘크리트 옹벽 전면벽체를 규정 깊이로 묻거나 바닥판 폭을 크게 하여, 활동에 대한 안전성을 높일 필요가 있다. However, in the right-angled concrete retaining wall, which is almost 90 ° as described above, in order to obtain a sufficient active resistance and at the same time clarify the prescribed value for the embedding depth of the concrete retaining wall, the concrete retaining wall front wall is buried at the specified depth or the bottom plate width is increased. Increasingly, it is necessary to increase the safety of the activity.

이 때문에, 콘크리트 옹벽의 소형화 및 경량화가 어려울 뿐만 아니라 중량이 무거운 콘크리트 옹벽을 운반할 때 및 시공상 소정의 위치에 콘크리트 옹벽 설치시 면합 및 높이 맞댐을 하는 작업 등 현장 시공성이 곤란한 문제가 있다. For this reason, it is difficult to reduce the size and weight of the concrete retaining wall, and there is a problem in that the field workability is difficult, such as when the heavy retaining wall is carried and when the concrete retaining wall is installed at a predetermined position in construction, the surface retaining wall and the height are matched.

특히, 콘크리트 옹벽의 설치에 앞서, 기초부의 높이와 기울기를 정밀하게 시공하기 위한 몰탈을 포설하기 위해 기초부상에서 바닥판의 연단측의 단면 부근과 전면벽체측의 단면 부근 및 바닥판의 양측면 소정의 위치에 목재 등으로 형틀을 짜고 그 내부에 몰탈을 채워 양생이 완료된 후 비로소 옹벽을 설치하게 되는 바, 인력시공에 의한 몰탈표면의 경사가 정교하지 못할 경우에는 철거후 재시공하거나 또는 추가 깔개가 필요해지는 등 시공상 문제가 발생되고 있다.In particular, prior to the installation of the concrete retaining wall, in order to install mortar for precisely constructing the height and inclination of the foundation portion, on the foundation portion, the vicinity of the end surface on the edge of the bottom plate, the vicinity of the end surface on the side of the front wall, and both sides of the bottom plate Retaining walls will be installed only after weaving the mold with wood, etc., and filling the mortar inside, and if the slope of the mortar surface due to manpower construction is not precise, reconstruction or additional rug will be needed. There is a problem in construction.

한편, 몰탈에는 무수축 몰탈을 사용해야 하는 등 설치비용의 증대를 가져와 한층 더 자원, 자재를 대량으로 소비하는 결점도 있다.On the other hand, there is a drawback in that the mortar has an increase in installation cost, such as the use of non-shrink mortar, and further consumes a lot of resources and materials.

또한, 기왕의 직각 콘크리트 옹벽에서는 상기 전면벽체의 높이 맞댐과 경사각 조정에 있어서, 기초부에 대해서 개수하지 않을 수 없는 경우에는 기초부 전면적에 있어서 재차 높이조정을 하지 않으면 안되는 결점이 있다. In addition, in the right-angled concrete retaining wall, there is a drawback in that the height adjustment and the inclination angle of the front wall have to be height-adjusted again in the entire area of the foundation when the number of the foundation has to be fixed.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로써, 옹벽을 구축하기 위한 부지가 좁고, 옹벽의 설치가 어려운 경우에서도 자중이 가볍고 시공성이 양호한 옹벽을 손쉽게 시공할 수 있으며, 바닥판에 둔각구간이 형성됨으로써, 배면토압에 의한 활동저항성을 증대시켜 근입심도를 감소시키므로 옹벽 구축시의 굴토나 성토 등의 토공량을 큰 폭으로 삭감시킬 수 있을 뿐만 아니라 옹벽에 사용되는 재료도 저감시킬 수 있도록 한 조립식 콘크리트 옹벽 및 그의 시공방법을 제공하는 것을 목적으로 한다. Therefore, the present invention has been devised to solve the above problems, the site for building the retaining wall is narrow, even when the retaining wall is difficult to install the retaining wall is light weight and good workability easily, As the obtuse section is formed on the bottom plate, it increases the activity resistance due to the back soil pressure and reduces the depth of rooting. Therefore, it is possible to drastically reduce the amount of earthwork such as pit soil and embankment when constructing the retaining wall, as well as the material used for the retaining wall. An object of the present invention is to provide a prefabricated concrete retaining wall and a construction method thereof that can be reduced.

이들 도면에 도시된 바와 같이, 본 발명에 따른 조립식 콘크리트 옹벽은 수직으로 배치됨과 동시에 내측면 소정의 위치에 배수공 겸 인양공(12)이 형성되고 일측단 수직구간(31)에는 연결부 수발공(11)이 형성된 전면벽체(10)와; 상기 전면벽체(10)의 하단에서 소정구간의 수평구간(32)과 둔각구간(34)으로 연장됨과 동시에 개구부(22)가 형성된 바닥판(20)과; 상기 전면벽체(10)와 바닥판(20)과의 사이에 수직구간(31), 수평구간(32)과 둔각구간(34)이 형성됨과 동시에 양측면에는 연결이음공(36)이 형성된 보강리브(30)로 구성된다.As shown in these drawings, the prefabricated concrete retaining wall according to the present invention is disposed vertically and at the same time the drainage and lifting hole 12 is formed at a predetermined position on the inner side, and one side end vertical section 31, the connection part hand hole 11 A front wall 10 formed with; A bottom plate 20 extending from the lower end of the front wall 10 to a horizontal section 32 and an obtuse section 34 of a predetermined section and at the same time having an opening 22; A vertical section 31, a horizontal section 32, and an obtuse section 34 are formed between the front wall 10 and the bottom plate 20, and at the same time, reinforcing ribs having connection holes 36 formed on both sides thereof ( 30).

여기서, 상기 바닥판(20)과 보강리브(30)에 소정의 수평구간(32)을 형성하는 이유는 운반 설치시 조립식 옹벽(W) 자체의 구조적 안정성을 확보하기 위함이고, 둔각구간(34)을 형성하는 이유는 배면토압에 의한 활동(sliding) 저항력을 증대시켜서 근입심도를 10㎝ 이상 적게 할 수 있어 경제적인 구조물을 설치할 수 있도록 하기 위함이다.Here, the reason for forming a predetermined horizontal section 32 in the bottom plate 20 and the reinforcing rib 30 is to ensure the structural stability of the prefabricated retaining wall (W) itself during transport installation, obtuse section (34) The reason for forming is to increase the sliding resistance due to the back earth pressure, so that the root depth can be reduced by 10 cm or more, so that an economical structure can be installed.

또한, 상기 개구부(22)에는 종횡으로 다수개의 철근(24)이 배근 설치된 구조이다.In addition, the opening 22 has a structure in which a plurality of reinforcing bars 24 are installed in a vertical direction.

그리고, 상기 보강리브(30)는 양측 보강리브(30a)와 1개 이상의 중앙 보강리브(30b)로 구분되며, 상기 양측 보강리브(30a)의 폭은 중앙 보강리브(30b)의 폭의 1/2로 형성되어 옹벽(W)의 연결 이음시 발생할 수 있는 구조적 취약점을 보강한 구조이며, 중앙 보강리브(30b)에는 인양을 위한 인서트너트(13)가 형성된 구조이다.The reinforcing rib 30 is divided into both reinforcing ribs 30a and one or more central reinforcing ribs 30b, and the width of the both reinforcing ribs 30a is 1 / the width of the center reinforcing ribs 30b. Formed to 2 is a structure that reinforces the structural weakness that may occur when connecting the retaining wall (W), the central reinforcing rib (30b) is a structure in which the insert nut 13 for lifting.

다시 말하면, 조립식 옹벽(W)의 인양 설치시에는 전면벽체(10)에 형성되는 2개의 인양공(12)과 중앙 보강리브(30b)상에 매입되어지는 인양 설치작업용 인서트너트(13)를 활용하여 특수볼트, 샤클 등으로 체결하여 무게중심을 잡고 이동시킴으로써 손쉬운 인양 설치작업을 가능하게 한다.In other words, when lifting the prefabricated retaining wall W, two lifting holes 12 formed in the front wall 10 and an insert nut 13 for lifting installation work embedded in the central reinforcing rib 30b are utilized. Fastening installation work is possible by fastening with a special bolt, shackle, etc. to grab the center of gravity and move.

즉, 본 발명에 따른 조립식 콘크리트 옹벽은 전면벽체(10)와 바닥판(20) 및 보강리브(30)가 유기적으로 일체로 결합된 구조이다.That is, the prefabricated concrete retaining wall according to the present invention has a structure in which the front wall 10, the bottom plate 20, and the reinforcing rib 30 are organically integrally coupled.

여기서, 상기 전면벽체(10)는 소정위치에 직경 50mm 정도의 배수공 겸 인양공(12)들을 형성하여, 시공성 향상은 물론 옹벽(W) 배면에 가해지는 토압에 대해서도 용이하게 대응토록 한 구조이다.Here, the front wall 10 is formed to form a drainage hole and the lifting hole 12 having a diameter of about 50mm in a predetermined position, it is easy to cope with the earth pressure applied to the back surface of the retaining wall (W) as well as improving the workability.

또한, 상기 바닥판(20)은 그 내측면에 개구부(22)를 형성하여, 옹벽(W)의 운반시 콘크리트의 자체중량을 현저히 감소시킨 구조이다.In addition, the bottom plate 20 has an opening 22 formed on the inner surface thereof, thereby significantly reducing the weight of concrete itself when the retaining wall W is transported.

그리고, 상기 보강리브(30)는 수평구간(32)과 둔각구간(34)으로 구분하여 형성하여, 옹벽(W)의 설치시 작업성을 개선하고 경제성을 향상시킨 구조이다.In addition, the reinforcing rib 30 is formed by dividing the horizontal section 32 and the obtuse section 34 to improve workability and economical efficiency when installing the retaining wall (W).

이하, 상기한 바와 같은 구성으로 이루어진 본 발명에 따른 조립식 콘크리트 옹벽의 시공에 대해 설명한다.Hereinafter, the construction of the prefabricated concrete retaining wall according to the present invention having the configuration as described above will be described.

The angle 44 is embedded in a precise position by surveying, and at the same time, the foundation concrete layer is formed, and the sub-mixing mortar 48 is poured on the foundation concrete layer up to the surface height of the height adjusting angle 44 to form the foundation portion B. To form.

이어서, 상기 기초부(B)상에 본 발명의 조립식 콘크리트 옹벽(W)들을 전면벽체(10)에 형성된 인양공(12)들과 중앙 보강리브(30b)에 형성된 인양용 인서트 너트(13)에 인양볼트를 끼워 인양하여 설치함과 동시에 좌우 양측보강리브(30a)에 형성된 연결이음공(36)들을 통해 볼트와 너트로 체결한 후, 상기 조립식 콘크리트 옹벽(W)의 바닥판(20)에 형성된 개구부(22)에 마감콘크리트(50)를 타설하여 기초부(B)의 부배합몰탈층과 일체화 되도록 옹벽(W)을 고정 설치토록 한다.Subsequently, the prefabricated concrete retaining walls (W) of the present invention on the base (B) to the lifting holes 12 formed in the front wall 10 and the lifting insert nut 13 formed in the central reinforcing rib 30b. At the same time, the lifting bolts are installed by lifting the bolts and nuts through the connecting joints 36 formed in the left and right reinforcing ribs 30a, and formed on the bottom plate 20 of the prefabricated concrete retaining wall W. The finishing concrete 50 is poured into the opening 22 to fix and install the retaining wall W so as to be integrated with the submixture mortar layer of the base B.

이어서, 상기 조립식 콘크리트 옹벽(W)들의 연결 조립 설치후 전면벽체(10)들의 수직구간(31) 맞이음부에는 5㎜내외의 폭으로 연결부 수발공(11)이 형성됨으로 도 9에 도시된 바와 같이 투수성을 갖는 필터층(38)을 옹벽(W) 배면에 설치하여 배면토의 유출을 방지하고 배면지하수를 유출시키도록 한다.Subsequently, after the connection assembly installation of the prefabricated concrete retaining walls (W) is connected to the vertical section 31 of the front wall (10), the connecting portion can be hole 11 is formed in a width of about 5mm, as shown in Figure 9 A filter layer 38 having a permeability is installed on the rear surface of the retaining wall W to prevent the outflow of the backing soil and to drain the back groundwater.

따라서, 상기한 바와 같은 구성 및 시공으로 이루어지는 조립식 콘크리트 옹벽은 바닥판(20)과 보강리브(30)를 수평구간(32)과 둔각구간(34)으로 구분함과 동시에 보강리브(30)를 다수개 설치하여 옹벽(W)을 구조적으로 보강하여 안정성을 도모하고, 또한 조립 설치시 높이조절용 앵글(44)을 활용하여 작업성이 향상되며, 바닥판(20)의 형성시 개구부(22)를 형성하여, 옹벽(W)의 자체중량을 경량화 시켜 운반 및 설치가 편리하며, 전면벽체(10)에 배수공(12)과 연결부 수발공(11)을 형성하여 토압을 감소시키며, 필요에 따라 다양한 전면문양(52)이나 화분(54)을 옹벽(W)의 전면에 설치하여 주위 환경의 미감을 도모할 수 있는 작용효과가 있다. Therefore, the prefabricated concrete retaining wall composed of the above-described configuration and construction divides the bottom plate 20 and the reinforcing rib 30 into the horizontal section 32 and the obtuse section 34 and at the same time a large number of the reinforcing ribs 30. Reinforcement of the retaining wall (W) structurally installed to improve stability, and also improve the workability by utilizing the height adjusting angle 44 during assembly installation, and forms the opening 22 when the bottom plate 20 is formed By reducing the weight of the retaining wall (W), it is convenient to carry and install, and to reduce the earth pressure by forming the drain hole (12) and the connecting part water-repellent hole (11) in the front wall 10, various front patterns as needed (52) or the potted plant 54 is installed on the front of the retaining wall (W) has an effect that can achieve aesthetics of the surrounding environment.

이상에서 설명한 바와 같이, 본 발명에 따른 조립식 콘크리트 옹벽 및 그의 시공방법은 옹벽을 구축하기 위한 부지가 좁아, 옹벽의 설치가 어려운 경우에서도 구조적으로 안정된 옹벽을 정밀하고 쉽게 시공할 수 있으며, 옹벽 구축시의 근입깊이를 감소시킬 수 있어, 굴토나 성토 등의 토공량을 큰 폭으로 삭감시킬 수 있을 뿐만 아니라 옹벽에 사용되는 재료도 저감시킬 수 있는 이점이 있다.As described above, the prefabricated concrete retaining wall and its construction method according to the present invention has a narrow site for constructing the retaining wall, so that even when the retaining wall is difficult to install, the structurally stable retaining wall can be accurately and easily constructed. It is possible to reduce the depth of incidence of not only a large amount of earthwork, such as oyster and fill, but also to reduce the material used for the retaining wall.
