What is necessary is just to reinforce the incision surface 21 by doing so.

상기와 같이 시공하는 과정에서 배수로가 필요할 시에는 도 4에서 제공하는 PC구조체(1)를 이용하여 배수로(11)를 형성하면 되는 것이다.(도 5, 도 6 참고)When the drainage path is needed in the construction process as described above, the drainage path 11 is formed by using the PC structure 1 provided in FIG. 4 (see FIGS. 5 and 6).

2) 석축(24) 대용으로 도로변의 낮은 경사면 보강용으로 사용2) Used for reinforcing low slopes of roadsides instead of stone shafts (24)

도로변의 낮은 경사면 보강용 석축(24)으로 사용코자 할 시에는 경사면의 하단에 바닥 지면을 고르는 작업으로 기초면을 형성하고, 이 기초면에 PC구조체(1)를 안치하고 좌면(4)과 우면(5)에 형성된 돌기(4a)와 홈(5a)이 상호 끼워지도록 배열하고, PC구조체(1)의 상면(2) 후방에 형성된 돌기(2a)에 적층되는 PC구조체(1)의 하면(3) 전방에 있는 홈(3a)이 끼워지게 하는 방법으로 적층하고, 적층된 PC구조체(1)들의 후방과 경사면 사이에 흙을 뒤채움하면 되는 것이다.In order to use as a low slope slope reinforcement stone 24 on the side of the road, the base surface is formed by selecting the floor ground at the bottom of the slope, and the PC structure 1 is placed on the foundation surface, and the left surface 4 and the right surface The lower surface of the PC structure 1 which is arranged so that the protrusions 4a and the grooves 5a formed at (5) are fitted to each other, and laminated on the protrusions 2a formed at the rear of the upper surface 2 of the PC structure 1 (3). In this case, the front grooves 3a may be stacked in such a manner that the front grooves 3a may be fitted, and the soil may be filled between the rear and the inclined surfaces of the stacked PC structures 1.

이때 PC구조체(1)들의 고정력을 높이고자 어스앵커(20)의 추가시공하고, 보 강철근 주입구멍(8)을 통해서 보강철근(23)을 내입하여 후 몰탈을 주입하여 상하측 PC구조체(1)를 상호 일체화 시키면 된다.(도 7 참고)At this time, the additional construction of the earth anchor 20 to increase the fixing force of the PC structure (1), the reinforcing bar 23 is inserted through the beam reinforcing steel injection hole (8) and then mortar is injected to the upper and lower PC structure (1) This can be integrated with each other (see Fig. 7).

3) 교량공사의 되 메우기 면의 측벽으로 활용3) Used as side wall of backfill surface of bridge construction

본 발명에서 제공하는 PC구조체(1)를 교량공사의 되 메우기 면의 측벽으로 활용코자 할 시에는 먼저 교량 폭과 동일하거나 조금 넓은 폭으로 마주보게 PC구조체(1)를 적층하여 벽체(25)를 형성하고, 마주보는 PC구조체(1)에 형성되어 있는 앵커구멍(9)을 통해 어스앵커(20)를 내입하여 양측 벽체(24)를 구성하는 PC구조체(1)를 인장 고정한 다음 양측 벽체(25) 내측 공간을 흙으로 되 메우기 하면 되는 것이다.(도 8, 도 9 참고)When using the PC structure (1) provided by the present invention as the side wall of the backfill surface of the bridge construction, first stacked the PC structure (1) facing the same or slightly wider width of the bridge width wall 25 And the PC structure 1 constituting the two side walls 24 is fixed by inserting the earth anchor 20 through the anchor hole 9 formed in the facing PC structure 1 and then the both side walls 25. This is done by filling the inner space with dirt (see Figs. 8 and 9).

이상과 같이 제조 및 시공되는 본 발명의 옹벽용 피씨구조체(1)는 절개면(21) 등의 보강을 위해 조성하는 옹벽을 공장에서 제작한 블록화된 PC구조체(1)에 의해 조성되게 한 것으로서, 본 발명에 의하면 거푸집 등의 설치 없이 공사가 가능하여 작업 공기를 대폭 단축할 수 있으면서도 견고한 설치상태를 제공할 수 있는 등 기대 이상의 효과를 득할 수 있는 것이다.The retaining wall PC structure 1 of the present invention manufactured and constructed as described above is to have a retaining wall formed for reinforcement of the incision surface 21 and the like by the blocked PC structure 1 manufactured at the factory. According to the present invention, the construction can be performed without installation of formwork and the like, and the working air can be significantly shortened, while still providing a solid installation state, and thus it is possible to obtain more than expected effects.

그리고 본 발명은 PC구조체(1)의 전면에 다양한 도형 혹은 문자 등을 형성할 경우 미감 제공과 함께 자연스러운 광고효과를 기대할 수 있는 것이다.And when the present invention forms a variety of figures or characters on the front of the PC structure (1) it can be expected a natural advertising effect with aesthetics.
