본 발명은 너클 이음 구조의 옹벽시공방법에 관한 것으로, 보다 상세하게는 토목공사가 시행된 도로 구간의 사면유실을 방지하기 위해 축조되는 보강토 옹벽을 인접된 블록의 측면끼리 상호 맞물리게 적층 시공함에 따라 토압에 의한 내구성을 향상시킴과 동시에 너클 구조에 의해 휘어짐이 요구되는 곡면부의 공사를 용이하게 할 수 있게한 너클 이음 구조가 이용되는 비탈면 보강토 옹벽 시공방법에 관한 것이다.The present invention relates to a retaining wall construction method of the knuckle joint structure, and more specifically, the earth pressure as the reinforcement soil retaining wall is constructed to prevent the slope loss of the road section in which the civil engineering work is carried out by interlocking with the sides of adjacent blocks This invention relates to a method for constructing a sloped reinforced soil retaining wall using a knuckle joint structure that facilitates construction of a curved portion requiring bending by a knuckle structure while improving durability.

일반적으로, 건축물을 신축하기 위한 택지조성이나 일반도로, 하천 및 호안공사 등의 토목공사를 할 때 절개면 또는 성토층의 유실을 방지하면서 조경을 겸할 수 있도록 콘크리트로 된 보강토 옹벽의 시공이 보편화되고 있다.In general, when constructing residential land for new construction or civil works such as general roads, rivers, and revetment works, the construction of reinforced concrete retaining walls made of concrete is common to prevent landslides or loss of soil layer. have.

종래의 대부분의 보강토 옹벽은 도 1에서와 같이, 비탈면(1)의 유실방지를 목적으로 한 것으로, 공사지점에 기초철골조를 시공하고 그 외측에 거푸집을 댄 후 콘크리트를 타설 및 양생하여 벽면 구조물(2)로 시공하게 된 기술이 주종을 이루고 있으나, 철근의 배근과 거푸집의 가설, 콘크리트 타설과 양생, 거푸집의 제거 및 마감처리 등 공정과 공사기간이 과다한 점과 작업을 위한 공간이 확보되어야 하는 점 등을 이유로 시공이 제한적일 수 밖에 없었다.Most conventional retaining soil retaining wall is intended to prevent the loss of the slope 1, as shown in Figure 1, by constructing the base steel frame at the construction site and the formwork on the outside of the concrete after placing and curing the wall structure ( 2) The technology that was constructed in 2) is mainly dominated, but the process and construction period such as reinforcement and reinforcement of reinforcing bars, concrete pouring and curing, removal and finishing of formwork and space for work must be secured. Construction was limited because of the back.

한편, 상기 철근 콘크리트 구조물로 된 옹벽의 취약점을 해소하기 위해 이른바, 보강토용 콘크리트 블록이 등장하였으나, 종래의 콘크리트 블록 시공방법은 동일형상의 블록을 서로 맞닿게 적층하되 블록의 후면을 성토층 또는 지중에 설치한 지지바에 와이어로 연결하여 지지되게 하였으므로 토압에 견디기 위한 응력이 취약 한 문제점이 있었다.On the other hand, in order to solve the weakness of the retaining wall made of the reinforced concrete structure, so-called reinforcement soil concrete block has appeared, the conventional concrete block construction method is to stack the same shape of the blocks in contact with each other, but the back of the block in the fill layer or underground There was a problem that the stress to withstand earth pressure was weak because it was connected to the support bar installed in the wire to be supported.

특히 블록을 곡면으로 이어지도록 축조하는 경우에는 인접된 블록끼리의 접촉범위가 극히 협소하여 결속력이 저하되었으므로, 우수에 의한 침식이나 토압이 가해지면서 변형력이 가해질 때 그 해당부분의 블록이 축조면으로부터 어긋나는 현상이 발생되어 심한 경우 붕괴가 발생되는 위험한 문제점도 있었다. In particular, when the block is constructed to be curved, the contact range between adjacent blocks is extremely narrow, and the binding force is reduced. Therefore, when the deformation force is applied while erosion or earth pressure is applied by rainwater, the block of the corresponding part is displaced from the surface of the building surface. There was also a dangerous problem that caused the phenomenon to collapse in severe cases.
