본 옹벽 시공방법은 거푸집을 사용하지 않고, 블럭을 적층한 후 횡철근과 종철근을 배근하고, 콘크리트를 충진시켜 블럭과 철근을 콘크리트로 일체화되게 양생시켜 시공되는 옹벽 시공방법에 관한 것이다.The retaining wall construction method relates to a retaining wall construction method that is constructed by stacking blocks without reinforcement and reinforcing transverse and longitudinal reinforcing bars, and filling the concrete so that the blocks and reinforcing bars are integrated with concrete.

지금까지의 옹벽 시공방법은 거푸집을 조립하고, 철근을 배근한 후 콘크리트를 타설하고, 양생된 후 거푸집을 철거하는 방법과 블럭을 적층시킨 후, 콘크리트를 충진시키는 방법이 있었으나, 거푸집 설치 방법은 과다한 인건비와 공사기간이 길어지는 점과 콘크리트 표면의 곰보현상, 골재 분리현상 등 많은 폐단과 막대한 공사비가 투입되는 문제점이 있었으며, 블럭을 사용하는 방법은 콘크리트 층진과 종철근만 배근할 수밖에 없으므로, 토압에 의한 안전도 문제로 인하여, 시공 높이가 1.5M를 초과할 수가 없었다.Up to now, retaining wall construction methods include assembling formwork, reinforcing reinforcing bars, placing concrete, curing and removing formwork, stacking blocks, and filling the concrete. There are problems such as long labor cost and construction period, many wastes and huge construction cost such as pumbo phenomena and aggregate separation of the concrete surface, and the method of using blocks only reinforces concrete stratification and longitudinal rebar due to the problems of safety, the construction could not exceed a height of 1. 5 M.

본 발명은 이상 설명한 바와 같은 종래 시공방법의 결점을 해결하기 위하여, 블럭의 상면 중앙부분에 콘크리트 충진공간을 확보하고, 횡철근 설치용 요홈을 2개소 천설하여, 옹벽의 높이와 토압의 정도에 따라 철근 배근을 한줄 또는 두줄(복근)로 시공할 수 있도록 구성하였으며, 또한, 옹벽이 높고 토압이 큰 곳의 시공을 위하여 블럭 후면 절단선을 절단하고, 옹벽 전면 설치선에 90°방향으로 블럭을 설치하여, 철근을 연결 시공하면 부벽식 옹벽 구조로서, 높은 옹벽 시공에도 안정된 구조로 시공될 수 있는 것이다.The present invention, in order to solve the shortcomings of the conventional construction method as described above, to secure the concrete filling space in the center of the upper surface of the block, and to install two grooves for installing the transverse reinforcement, reinforcement according to the height of the retaining wall and the degree of earth pressure It is designed to install one line or two lines (abdominal muscles), and also cut the cutting line at the back of the block for the construction of the place where the retaining wall is high and the earth pressure is large. When the reinforcing bars are connected, it is a subwall retaining wall structure, which can be constructed in a stable structure even in a high retaining wall construction.

이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

기본부재(1)의 블럭 전면(2)을 곡면화하고, 블럭 배면판(3)은 평면화하여, 시공시 전, 후면을 선택 시공할 수 있도록 하였으며, 블럭 전면 판(4)과 블럭 후면 날개(5)사이에 전후면 블럭판 연결부(6)을 형성시키고, 블럭 상단면 중앙부분을 낮추어 횡방향 콘크리트 충진공간(6')을 확보하고, 횡철근 교정 요홉(7)을 2줄로 천설하여, 횡철근 간격을 일정하게 유지시키게 되며 부재(1)를 1개층 설치하고, 횡철근(9)을 횡철근 요홈(7)에 배근하여 종철근(10)과 결속시킨 후 반복 적층 시공하며, 부벽식 날개 시공시는 시공위치의 기본부재(1)의 블럭 후면 절단선(8)을 절단하고, 옹벽 전면 방향의 90°방향으로 기본부재(1)를 연결 설치하여, 옹벽 전면블럭선에 배근된 횡철근(9)과 날개부분에 배근된 횡철근(9)을 연결하여, 소정의 옹벽 높이까지 쌓아 올린 후, 콘크리트 충진 공간(6')을 통하여 인접한 상, 하, 좌, 우 기본부재(1)와 횡철근(9), 종철근(10), 기초 콘크리트(11)가 일체로 양생되어, 완벽한 옹벽이 구축되는 것이다.The front block 2 of the base member 1 is curved, and the block back plate 3 is flattened so that the front and rear sides of the block can be selected before construction. The block front plate 4 and the block rear blades ( 5) Form the front and rear block plate connection part 6 between them, lower the center of the block top surface to secure the transverse concrete filling space 6 ', and install the horizontal rebar straightening yog 7 in two rows. The rebar spacing is kept constant, one layer of member (1) is installed, the rebar (9) is reinforced to the transverse groove (7) and the longitudinal reinforcing bars (10) are combined with the repetitive lamination, and the sub-wall wing When constructing, cut the rear cutting line 8 of the block rear part of the base member 1 at the construction position, install the base member 1 in the 90 ° direction of the retaining wall front direction, and install the transverse reinforcement to the retaining wall front block line. (9) and the horizontal reinforcing bar (9) connected to the wing portion, piled up to a predetermined retaining wall height, and then filled with concrete The upper, lower, left, and right base members 1, the transverse bars 9, the longitudinal reinforcing bars 10, and the base concrete 11 are integrally cured through the space 6 'to form a perfect retaining wall. .

미 설명부호(11)은 기초콘크리트, (12)는 기초철근, (13)은 성토, 절토면(14)는 옹벽 상단 보호 콘크리트이다.Unexplained reference numeral 11 is the foundation concrete, 12 is the basic reinforcement, 13 is the fill, cut surface 14 is the retaining wall top protection concrete.

본 시공방법은 기초 콘크리트 타설후 종철근을 옹벽 높이와 동일하게 기초철근에 결속하여, 배근하고 종철근 사이에 단위부재(1)를 축조하면서, 매층마다 철근의 배근형태와 배근량을 토압이나 옹벽의 구조에 맞도록 선택적으로 사용할수 있으므로서 경제적인 옹벽축조가 가능한 것이다.In this construction method, after the foundation concrete is laid, the longitudinal reinforcing bars are fastened to the basic reinforcing bars at the same height as the retaining wall, and the unit members 1 are constructed between the longitudinal reinforcing bars. Economical retaining wall construction is possible because it can be selectively used to fit the structure of

It is a feature of the present invention.

본 시공방법은 거푸집 설치, 해제 인건비가 절감됨은 물론, 규격화, 양상화된 균일한 품질의 블럭을 사용하므로, 미려한 콘크리트 옹벽 면이 시공되며, 공사기간이 단축되어, 대폭적인 공사비 절감을 꾀할 수 있는 매우 유용한 발명인것이다.This construction method not only reduces the cost of installing and removing formwork, but also uses standardized, uniform, uniform quality blocks, so that the beautiful concrete retaining wall is constructed and the construction period is shortened, resulting in significant cost savings. It is a very useful invention.
