PC 강선의 다른 끝은 강선 인장기(도시않됨)에 의해서 당겨져 이웃한 옹벽은 밀착된다. 여기에서 사용되는 PC 강선 및 강선 인장기는 종래에 사용되던 기술이므로 상세한 설명은 하지 않는다.Figure 5 shows the installation method of the prefabricated retaining wall of the present invention, when the neighboring retaining wall is installed in succession, the PC steel wire 10 is inserted into each groove 4 and one end of the PC steel wire at the connecting opening (5) Secure with anchorage. The other end of the PC steel wire is pulled by a wire tensioner (not shown) so that the adjacent retaining wall is in close contact. Since the PC steel wire and the wire tensioner used herein are techniques used in the related art, detailed description thereof will not be provided.
그 후에 이웃한 조립식 옹벽의 각각의 측면에 설치된 아이볼트(7)가 엇갈려 위치되면 아이볼트(7)의 고리 사이로 강봉(9)을 삽입하여 조립된다.Then, when the eye bolts 7 installed on each side of the neighboring prefabricated retaining walls are staggered, the steel rods 9 are inserted between the rings of the eye bolts 7 and assembled.
조립식 옹벽의 연결작업이 완료되면, 수평벽(2)의 강봉 삽입홈(8)에 마개(11)를 막고 그라우팅 홈(6)에 몰타르를 주입하여 고정시킨다.When the connection work of the prefabricated retaining wall is completed, the stopper 11 is plugged into the steel rod insertion groove 8 of the horizontal wall 2 and the mortar is injected into the grouting groove 6 to fix it.
도6에는 본 고안의 조립식 옹벽의 일 실시예가 도시되는데, 본 고안의 조립식 옹벽의 내측에 흙이 메워지는 L 자형 설치상태가 도시된다. 수평벽(2)의 그라우팅 홈(6)의 강봉 삽입홈(8)은 코너부(3)를 관통하여 좌측으로 형성된다. 수직벽(1)의 내측과 수평벽(2) 위에는 흙이 쌓여지고 흙위에는 보도블럭(12)이 설치된다.Figure 6 shows an embodiment of the prefabricated retaining wall of the present invention, the L-shaped installation state is filled with the soil inside the prefabricated retaining wall of the present invention is shown.
