Description

조립식 옹벽구조{Structure for fabricated retaining wall}Structure for fabricated retaining wall

본 발명은 조립식 옹벽구조에 관한 것으로서, 더욱 상세하게는, 옹벽을 형성함에 있어서, 옹벽시공을 위한 별도의 거푸집을 설치하지 않고 빠른 기간 내에 견고하고 미려한 옹벽을 시공할 수 있도록 한 조립식 옹벽구조에 관한 것이다.The present invention relates to a prefabricated retaining wall structure, and more particularly, to a prefabricated retaining wall structure in which a solid and beautiful retaining wall can be constructed in a short period of time without installing a separate formwork for retaining wall construction. will be.

일반적으로 옹벽은, 도로, 공원지역의 비탈면, 하천제방, 해안도로, 주거지역의 사면 등과 같은 곳의 현장에서 철근과 거푸집을 설치하고 콘크리트를 타설하는 현장 습식공사로 시공하여 왔고, 이에 의해 시공된 옹벽으로는 역 T자형 옹벽이 가장 많다.In general, the retaining walls have been constructed by site wet construction where reinforcing bars and formwork are installed and concrete is installed at sites such as roads, slopes in park areas, river embankments, coastal roads, and slopes in residential areas. The most retaining wall is an inverted T-shaped retaining wall.

이와 같이 현장에서 콘크리트를 타설하여 시공되는 옹벽은 지반굴착, 기초콘크리트 타설, 철근조립, 본체 콘크리트 타설, 뒷채움 공사 등의 과정을 거친다.As such, the retaining wall constructed by placing concrete in the site undergoes ground excavation, foundation concrete casting, reinforcing steel assembly, body concrete casting, and backfilling.

즉, 종래 옹벽시공은 현장에서 옹벽의 배근도를 참조하여 철근의 배근 작업을 수행해야 하고 거푸집을 설치한 후, 콘크리트를 타설하고, 콘크리트가 자립을 위한 강도를 유지하는데 대략 7일 이상의 양생기간이 필요하며, 양생 완료 후 거푸집을 해체하게 된다. 이에 따라 종래의 옹벽시공은 여러 단계의 시공과정 및 긴 공사기간이 소요되기 때문에 경제성 및 시공성에서 문제점이 있다. 또한 상기와 같은 종래의 시공방법으로 인해 장기간의 차량통행 차단과 우회도로 확보 등으로 인해 민원발생가능성이 높으며, 장기간 위험에 노출되는 문제점이 있어서 안정성 측면에서도 불리한 단점이 있다.That is, the conventional retaining wall construction needs to perform the reinforcement work of the reinforcement with reference to the reinforcement of the retaining wall in the field, and after the formwork is installed, it needs about 7 days or more to cure the concrete and maintain the strength for the self-reliance. After the curing is completed, the formwork is dismantled. Accordingly, the conventional retaining wall construction has a problem in economical and constructability because it takes several steps of construction process and a long construction period. In addition, due to the conventional construction method as described above, there is a high possibility of civil complaints due to long-term vehicle traffic blocking and securing a detour road, and there is a disadvantage in terms of stability since there is a problem of exposure to danger for a long time.

따라서 이러한 문제점으로 인해 최근에는 시공성, 경제성, 민원발생 가능성 측면을 고려하여 프리캐스트 콘크리트 옹벽(이하 'PC옹벽'이라 한다.)의 사용이 점차 증가되고 있는 추세이다. PC옹벽은 옹벽블록을 공장에서 제작하여 현장에서는 단지 조립만 실시하므로 시공성에서 매우 우수하며, 이에 따른 민원발생 가능성도 최소화할 수 있으므로 교통량이 적은 복잡한 도심지나 긴급한 공사에 매우 효과적이다.Therefore, due to these problems, the use of precast concrete retaining walls (hereinafter referred to as 'PC retaining walls') is gradually increasing in consideration of constructionability, economic feasibility, and the possibility of civil complaints. The PC retaining wall is very effective in construction because the retaining wall block is manufactured at the factory and only assembled at the site, and the possibility of civil complaints can be minimized.

그러나 위와 같은 개념으로 가장 오래된 프리캐스트 부벽식 옹벽은 공장에서 제작한 프리캐스트 콘크리트 블록을 현장에서 조립 설치하여 시공되는 것으로, 프리캐스트 콘크리트 옹벽블록 벽체부를 수평 및 수직방향으로 조립설치하고, 일종의 부벽 기능을 가지는 지지체를 벽체부와 기초판 사이에 경사지게 설치하게 된다. However, the oldest precast subwall retaining wall is constructed by installing precast concrete blocks manufactured at the factory in the field. The precast concrete retaining wall block wall parts are assembled and installed in horizontal and vertical directions. The support having a slope is installed between the wall portion and the base plate.

그런데, 위와 같은 프리캐스트 부벽식 옹벽은 별도로 벽체부 후면 전체에 다수의 지지체를 설치하게 되므로 일반적인 콘크리트 옹벽에 비해 시공성에서 우수할 수 없다는 문제점이 있다. 따라서 이러한 문제점을 개선하기 위해 다양한 옹벽구조 또는 옹벽시공방법 등이 제안된 바 있으나 그 구조가 복잡하여 시공현장의 조건 등이 열악할 경우 공사기간이 많이 소요되고 따라서 이 또한 비경제적인 문제점이 있다.However, the precast subwall retaining wall as described above has a problem in that it is not excellent in workability compared to a general concrete retaining wall because a plurality of supports are separately installed on the entire rear wall portion. Therefore, various retaining wall structures or retaining wall construction methods have been proposed to improve these problems. However, if the conditions of the construction site are poor due to the complicated structure, a lot of construction time is required, and thus there is also an uneconomic problem.

따라서 본 발명의 목적은, 기초콘크리트구조물에 조립식 옹벽구조를 다단식조립에 의한 원하는 높이로 입설할 수 있도록 함으로서 콘크리트타설공간을 형성하기 위한 별도의 거푸집을 형성하지 않고도 견고하고 미려하며 수직도가 정확한 옹벽을 형성할 수 있도록 함과 아울러 공사기간을 단축하여 인력 및 인건비를 감축할 수 있도록 한 조립식 옹벽구조를 제공하는 것이다.Therefore, an object of the present invention, by allowing the prefabricated retaining wall structure to be placed in the desired height by the multi-stage assembly to the foundation concrete structure, without having to form a separate formwork for forming the concrete casting space, solid, beautiful and vertically accurate retaining wall It is to provide a prefabricated retaining wall structure that can reduce the manpower and labor costs by reducing the construction period and at the same time.

이상에서 설명한 바와 같이 본 발명에 따르면, 기초콘크리트구조물에 콘크리트타설공간을 형성하기 위한 거푸집을 형성하지 않기 때문에 공사기간을 단축할 수 있음과 아울러 인력 및 인건비를 감축하는 이점이 있으며, 전면옹벽블록의 전면에 다양한 모양 및 문양 등을 사전에 형성할 수 있기 때문에 종래 옹벽 전면의 획일적인 모양 및 문양에서 벗어나 미려함을 창출할 수 있고, 콘크리트에 의해 타설된 옹벽의 전 후면에 전면옹벽블록 및 후면옹벽블록을 두고 콘크리트를 타설하기 때문에 견고한 옹벽을 형성하는 효과가 있으며 특히, 전면 및 후면옹벽블록의 일 측에 설치한 수직유지부재를 사용하여 전면옹벽블록 및 후면옹벽블록 상호 간의 수직상태를 유지할 수 있기 때문에 입설된 조립식 옹벽구조를 정확한 수직상태로 시공할 수 있다.As described above, according to the present invention, since the formwork for forming the concrete placing space is not formed in the foundation concrete structure, it is possible to shorten the construction period and reduce the manpower and labor costs. Since various shapes and patterns can be formed on the front surface in advance, it is possible to create a beauty out of the uniform shape and pattern of the conventional retaining wall front surface. Since the concrete is poured in place, it has the effect of forming a solid retaining wall. In particular, the vertical retaining member installed on one side of the front and rear retaining wall blocks can be used to maintain the vertical state between the front retaining wall block and the rear retaining wall block. The installed prefabricated retaining wall structure can be constructed in a precise vertical position.
