Description

배수공 설치용 옹벽거푸집구조{Formwork system for Retaining wall, taking care of weepholes}Retaining wall formwork for drainage hole installation {Formwork system for Retaining wall, taking care of weepholes}

본 고안은 옹벽거푸집 구조에 관한 것으로, 더욱 자세하게는 옹벽배면의 배수를 위해 설치되는 배수공(weephole) 파이프(Pipe)를 고정시킬 수 있는 구조를 거푸집 일측(배면측)에 구비하여, 옹벽 거푸집 작업시에 상기 콘크리트 옹벽에 매입되는 배수공의 설치를 용이하게 할 수 있는 옹벽거푸집구조에 관한 것이다.The present invention relates to a retaining wall formwork structure, and more specifically, to the one side (rear side) of the formwork to fix a weephole pipe (Pipe) installed for drainage of the retaining wall back, when retaining wall formwork It relates to a retaining wall formwork structure that can facilitate the installation of a drain hole embedded in the concrete retaining wall.

일반적으로 옹벽배면에는 성토되거나, 채움재의 자중으로 인한 토압이외에도 지하수위의 변화에 따라 토압이 증감하게 된다. 특히 지하수위의 상승은 배면토사의 내부마찰각의 감소와 토입자간 점착력의 저하로 이어져 토압증가의 주요인이 된다.In general, in addition to the earth pressure due to the earth retaining wall, or due to the weight of the filling material, the earth pressure increases or decreases as the groundwater level changes. In particular, an increase in the groundwater level leads to a decrease in the internal friction angle of the rear soil and a decrease in the cohesion between the soil particles, which is the main cause of the increase in earth pressure.

이러한 이유로 옹벽 배면의 배수는 옹벽구조물의 안전에 있어서 매우 중요한 문제이며 옹벽 배면의 수압을 배제하기 위해 배수공을 옹벽의 면적에 상응하는 일정비율로 설치하게 된다.For this reason, the drainage of the retaining wall back is a very important issue for the safety of the retaining wall structure, and the drainage holes are installed at a constant ratio corresponding to the area of the retaining wall to exclude the hydraulic pressure on the back wall.

통상적으로 배수면적은 옹벽 4㎡당 60㎠가 적당하며 보통 배수공은 직경 5∼10㎝ 의 염화비닐파이프(PVC Pipe)를 3m 이내의 간격으로 설치한다.Generally, the drainage area is suitable for 60 cm2 per 4m2 of retaining wall, and the drainage hole is usually provided with a PVC pipe of 5 to 10 cm in diameter within 3m intervals.

또한, 배수공의 설치시에는 원활한 배수를 위해 배면측에서(Back Face) 전면측으로(Front Face)측으로 일정경사를 갖게 된다.In addition, when the drain hole is installed, it has a constant slope from the back face to the front face for smooth drainage.

그러나, 옹벽에 있어서 배수공이 제대로 설치되지 않아 배면의 수압을 용이하게 배제하지 못한 경우에는 옹벽의 붕괴로 이어져 막대한 재산상의 피해는 물론 인명의 손실을 가져오는 예를 장마철에는 언론매체를 통해 어렵지 않게 접하게 되는 것이 현실이며 대표적인 예로 OO아파트 축대 붕괴사고 등이 있다.However, if the drainage hole is not properly installed in the retaining wall and the water pressure on the back is not easily excluded, the retaining wall collapses, resulting in enormous property damage and loss of life in the rainy season. The reality is that the OO apartment shaft collapse accident is a typical example.

상기와 같은 유형의 붕괴사고의 원인은 여러가지 측면에서 고찰하고 찾을 수 있겠으나 옹벽의 시공에 있어서 종래에 사용하고 있었던 배수공 설치와 거푸집의 구조에도 그 한 원인이 있다.The cause of the collapse of this type can be considered and found in various aspects, but there is also one cause in the construction of the drain hole and the formwork used in the construction of the retaining wall.

일반적으로 옹벽거푸집 시공시에 염화비닐파이프(PVC Pipe)의 설치는 배수공이 설치되는 배면거푸집의 소정위치에 염화비닐파이프(PVC Pipe)를 직경 이상의 구멍을 천공하여 시공하였으나, 이 때에는 거푸집을 반복사용할 수가 없어 공사비 증가의 한 요인이 되었다.In general, the installation of the PVC pipe during the retaining wall formwork is performed by drilling a PVC pipe at a predetermined position on the back side where the drain hole is installed, but using the formwork repeatedly. This was a factor in the increase in construction costs.

이러한 제약요소 때문에 거푸집 내측간격에 상당하는 길이로 염화비닐파이프(PVC Pipe)를 절단하여 옹벽구조물내의 철근에 고정하는 방법을 채택하여 시공하기도 하나 콘크리트 타설압력으로 인해 매입위치가 변화하여 배수공이 일정경사를 유지하지 못하거나 또는 염화비닐파이프(PVC Pipe)와 거푸집이 밀실하게 고정되지 않아 콘크리트 타설중 시멘트페이스트가 유입되어 배수공이 막히는 등, 배수홀로서의 기능이 저하되는 문제점이 있었다.Due to this constraint, the PVC pipe is cut to a length corresponding to the inner space of the formwork and fixed to the reinforcing steel in the retaining wall structure.However, the embedding position is changed due to the concrete placing pressure. There is a problem in that the function as a drainage hole is degraded, such as not being maintained or the PVC pipe and the formwork are not tightly fixed, so that cement paste is introduced during concrete pouring and clogged drain holes.

따라서, 본 고안응 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 정확한 위치에 배수공을 설치하므로서 옹벽의 배수성능을 보장할 뿐만아니라 가설재인 거푸집을 수회 반복사용할 수 있는 즉, 경제적이고 품질과 안전을 보장할 수 있는 옹벽구조물의 시공이 가능한 배수공 설치용 옹벽거푸집 구조를 제공하는 데 그 목적이 있다.Therefore, the present invention has been devised to solve the problems as described above, by ensuring the drainage performance of the retaining wall by installing the drain hole in the correct position, it is possible to repeatedly use the formwork as a temporary material, that is, economical and quality and safety It is an object of the present invention to provide a retaining wall formwork for installing a drainage hole capable of constructing a retaining wall structure that can be guaranteed.

상기 목적을 달성하기 위한 본 고안은, 옹벽거푸집의 일측내면에 고정목(60)이 부착되어 있고 고정목은 배수공 설치용 파이프(Pipe)(70)의 외경보다 큰 직경의 원통형 홀(90)이 중앙부에 관통되어 형성된 것을 그 특징으로 한다.The present invention for achieving the above object, the fixed neck 60 is attached to one inner surface of the retaining wall formwork, the fixed neck is a cylindrical hole 90 of diameter larger than the outer diameter of the pipe (70) for the installation of the drain hole It is characterized in that it is formed through.

이하, 첨부된 도면을 참조하면서 본 고안에 따른 바람직한 실시예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도2a는 본 고안에 따른 배수공의 시공상태의 일실시예를 도시한 단면도이다. 도2a에 도시된 바와 같이, 일반적으로 옹벽 전면측(10)의 거푸집 내측에는 구조물 완성후의 미관 등을 고려한 퍼블릭디자인의 개념의 경관설계가 도입되어 스티로폼(Styrofoam) 재질로 된 두께 약 25㎜∼50㎜의 문양거푸집을 사용하게 된다.Figure 2a is a cross-sectional view showing an embodiment of the construction of the drain hole according to the present invention. As shown in Figure 2a, generally, the interior of the retaining wall front side 10, the landscape design of the concept of public design considering the aesthetics after the completion of the structure is introduced, the thickness of about 25mm ~ 50 made of Styrofoam material The pattern mold of mm is used.

이 때, 배수공 염화비닐파이프(PVC Pipe)의 설치는 배면측(20) 거푸집에 부착되어 있는 고정목(60)의 중앙부 홀에 삽입한 후, 전면측(10) 거푸집 소정의 위치로 서서히 이동시켜 스티로폼에 밀착 압입하여 고정하면 된다. 배수공 설치작업은 좌·우 측면의 거푸집을 적어도 한쪽은 마감하지 않은 상태에서 작업자가 자유로이 통행하면서 작업이 가능하다.At this time, the installation of the drain pipe vinyl pipe (PVC Pipe) is inserted into the center hole of the fixed wood 60 attached to the back side 20 formwork, and then gradually moved to the predetermined position at the front side 10 formwork. It is good to press-fit into styrofoam and fix it. The drainage installation work can be done while the worker freely passes the formwork at the left and right sides without finishing.

또한, 배면측 고정목의 두께{Tb}(62)는 전면측에 압입되는 깊이보다 큰 치수로 제작하는 것이 바람직하다.In addition, it is preferable that the thickness {Tb} 62 of the back fixed wood is produced to a dimension larger than the depth to be press-fitted to the front side.

도3a는 본 고안에 따른 고정목의 일실시예의 단면도이다. 고정목은 현장에서 구득이 쉽고 흔한 자재인 목재를 활용하여 제작하는 데, 형상에 구애됨이 없이, 배수공 설치용 파이프(Pipe)(70)의 외경보다 큰 직경의 원통형 홀(90)이 중앙부에 관통되어 형성되면 충분하다.Figure 3a is a cross-sectional view of one embodiment of a fixed neck according to the present invention. The fixed wood is produced by using wood, which is easy to obtain in the field and is a common material, without being limited in shape, a cylindrical hole 90 having a diameter larger than the outer diameter of the pipe 70 for drainage installation penetrates to the center part. It is enough if it is formed.

고정목(60)으로 인해, 구조물 완성 후, 철근의 노출이나 피복두께의 확보에 대해 우려가 되는 경우에는 거푸집 해체 후, 배수공 이외의 공간(120)에 패칭(Patching)을 하거나 또는 목재고정목(60) 대신 몰탈(130)로 제작된 콘크리트제의 고정목을 사용하게 된다.Due to the fixed wood 60, after the completion of the structure, if there is concern about the exposure of the rebar or securing the coating thickness, after dismantling the formwork, patching (Patching) in the space 120 other than the drain hole or wood fixed wood ( 60) instead of using the mortar 130 made of concrete made of wood.

도3c는 콘크리트제의 고정목 제작에 대한 개념도이다. 이 때, 콘크리트제의 고정목 제작완료 후, 배면측 거푸집에 부착할 수 있도록 제작하는 것이 무엇보다 중요하며 고정목의 두께(62)보다 큰 길이를 갖는 못(80)에 소정의 길이로 재단된 빨대(110)을 삽입하여 형틀에 박아 제작하면, 양생된 고정목을 배면측 거푸집에 부착할 때, 파손을 방지할 수 있게 된다.Figure 3c is a conceptual diagram for the production of fixed wood made of concrete. At this time, after the completion of the production of the fixed wood made of concrete, it is important to manufacture so that it can be attached to the back side formwork and cut to a predetermined length in the nail 80 having a length greater than the thickness of the fixed wood (62) When the straw 110 is inserted into the mold and manufactured, when the hardened fixed wood is attached to the back side formwork, it is possible to prevent breakage.

고정목의 중앙부에 위치하는 원통형 홀(90)의 형성은 배수공으로 사용할 염화비닐파이프(PVC Pipe)(70)를 종이나 비닐(100)으로 감싸면 고정목 양생 후, 쉽게 분리할 수 있으며 배수공에 설치되는 염화비닐파이프(PVC Pipe)(70)의 외경보다 약간 커서 작업에 용이한 적정크기의 내경을 유지할 수 있게 된다.Formation of the cylindrical hole 90 located in the center of the fixed wood can be easily removed after curing the fixed wood by wrapping the PVC pipe (70) to be used as drain holes with paper or vinyl (100) It is slightly larger than the outer diameter of the PVC pipe (PVC Pipe) to be able to maintain the inner diameter of the appropriate size easy to work.

도 4는 본 고안의 또다른 실시예로서 전면측(10) 거푸집에 문양거푸집(50)을 사용하지 않는 경우에 배면측 고정목(60)보다 작은 크기의 두께(61)를 갖는 고정목을 사용함으로서 본 고안 소기의 목적을 달성하게 된다.4 is used as a fixing wood having a thickness 61 of a smaller size than the rear fixing wood 60 in the case of not using the design formwork 50 in the front side (10) formwork as another embodiment of the present invention By doing so, the object of the present invention is achieved.

상기와 같은 본 고안에 의하면, 옹벽용 거푸집 작업시에 거푸집을 훼손하지 않고 배수용 염화비닐파이프(PVC Pipe)를 설치할 수 있어 경제적인 시공을 할 수 있고, 거푸집 양측에 파이프(Pipe)를 밀실하게 설치가능하고, 정확한 위치에 매입시킬 수 있는 등 시공완료 후, 배수공의 기능확보에 있어 품질관리에 우수한 효과가 있다.According to the present invention as described above, it is possible to install a PVC pipe for drainage without damaging the formwork in the retaining wall formwork, so that economical construction can be achieved, and the pipes are tightly sealed on both sides of the formwork. After completion of construction, such as installable, can be embedded in the correct position, there is an excellent effect in quality control in securing the function of the drain hole.
