It is about retaining wall using PHC pile which can be installed easily and very economically.
일반적으로 옹벽이라 함은 배후의 토사의 붕괴를 방지할 목적으로 만들어지는 구조물을 말하며, 배후의 토압에 대하여 옹벽의 자중으로 안정을 유지하는 구조물이다.In general, the retaining wall refers to a structure that is made for the purpose of preventing the collapse of the soil behind, and is a structure that maintains stability by the weight of the retaining wall against the earth pressure behind.
옹벽의 종류로는 무근 콘크리트로 만들어지며 자중에 의해 안정을 유지하는 중력식 옹벽과 철근 콘크리트로 만들어지며 벽체, 뒷판, 앞판으로 구성되고 이들이 각각 캔틸레버로 작용하는 캔틸레버 옹벽, 캔틸레버 옹벽의 후면에 일정한 간격의 부벽을 설치하여 보강한 뒷부벽식 옹벽, 캔틸레버 옹벽의 전면에 일정한 간격의 부벽을 설치하여 보강한 앞부벽식 옹벽이 있다.The type of retaining wall is made of unreinforced concrete, and it is made of gravity retaining wall and reinforced concrete, which is stabilized by its own weight. There are rear wall retaining walls reinforced with subwalls and front wall retaining walls reinforced with subwalls of regular spacing on the front surface of the cantilever retaining wall.
이러한 종래 옹벽 중 가장 널리 이용되는 캔틸레버 옹벽의 시공순서를 보면, 옹벽을 시공할 곳에 터파기를 하고 기초면을 정리한 후 기초 콘크리트를 타설하고 지내력이 부족할 경우에는 지반개량 또는 파일을 설치한 후 바닥 철근을 배근하고 콘크리트를 타설하며 다음으로 벽체 철근을 배근하고 콘크리트를 타설하여 옹벽을 완성하게 된다.According to the construction procedure of the cantilever retaining wall, which is the most widely used among these retaining walls, when reinforcing the retaining wall and arranging the foundation surface, the foundation concrete is poured and if the bearing strength is insufficient, the ground reinforcement is installed after the ground improvement or pile is installed. We will reinforce the concrete and place concrete, and then we will reinforce the wall reinforcement and pour concrete to complete the retaining wall.
따라서 철근의 조립, 거푸집 및 비계의 설치, 콘크리트의 타설 등으로 이루어진 복잡한 공정을 거쳐 설치가 완료됨으로서 공기가 길어지고 공사비가 증가함은 물론 현장 노무자의 숙련도에 따라 품질이 결정되는 문제점이 있다.Therefore, the installation is completed through a complex process consisting of assembling the reinforcing bar, the installation of formwork and scaffolding, concrete pouring, etc., there is a problem that the air is long, the construction cost increases, and the quality is determined according to the skill of the field laborer.
