Description

토목공사용 흙막이 벽체{Retaining wall for engineering works}Retaining wall for engineering works

본 발명은 토목공사용 흙막이 벽체에 관한 것으로, 더욱 상세하게는 버팀말뚝과 버팀말뚝 사이에 지지패널을 설치하고, 제1,2지지패널 사이에 콘크리트를 타설하여 벽체를 형성함으로써 작업성이 향상되고 콘크리트 타설시 휨변형을 방지할 수 있는 토목공사용 흙막이 벽체에 관한 것이다.The present invention relates to a retaining wall for civil engineering work, and more particularly, by installing a support panel between a support pile and a support pile, and pouring concrete between the first and second support panels to form a wall, workability is improved and concrete It relates to a retaining wall for civil engineering works that can prevent bending deformation during pouring.

신축건물을 계획함에 있어서 지하구조물은 거의 필수적으로 만들어져야 한다. 지하구조물을 시공하기 위해서는 계획심도까지 터파기하기 위해서는 흙막이가시설을 시공하여야 한다. In planning a new building, an underground structure is almost indispensable. In order to construct an underground structure, it is necessary to construct a retaining system in order to dig up to the planned depth.

흙막이가시설은 대지경계로부터 사업부지 내측으로 시공되어야 하고, 터파기를 완료한 후에는 흙막이가시설 내측에 지하구조물 본 벽체를 시공하여야 하므로 사업부지 지하공간이 흙막이가시설에 사용된 부지만큼 감소하게 된다. 이 공간은 부지의 최외측라인에 해당하기 때문에 그 감소면적은 상당히 큰 편이다.The retaining facility must be constructed from the site boundary to the inside of the project site, and after the excavation is completed, the main wall of the underground structure must be installed inside the retaining facility. . Since this space corresponds to the outermost line of the site, the reduced area is quite large.

이러한 사항으로 인해 종래부터 실무자들은 흙막이가시설을 그대로 지하구조물의 본 벽체로 사용할 수 있는 방법을 강구해보고자 많은 노력을 기울여 왔으나 터파기 방법에 대한 것과 본 벽체에 배근하여야 할 철근부재 설치의 부적정과 같은 문제점에 봉착하게 되어 이 문제점을 해결하지 못해 온 것이 현실이다.Due to these issues, the practitioners have made a lot of effort to find a way to use the retaining system as the main wall of the underground structure as it is. The reality is that we have been facing the same problem and have not been able to solve this problem.

또한, 종래에는 측면말뚝의 천공공간에서의 채움불량, 흙막이판을 설치하기 위해 측면말뚝과 측면말뚝 사이의 공간을 터파기 하는 과정에서 배면토의 이완, 여굴 발생, 여굴공간의 채움불량 등으로 배면지반이 침하하는 등의 문제가 발생하고 있다.In addition, in the prior art, the back ground is due to the loosening of the back soil, the occurrence of overburden, poor filling of the overburden space, etc. in the process of excavating the space between the side pile and the side pile to install the retaining plate. Problems such as this subsidence are occurring.

또한 시간이 지남에 따라 버팀대의 압력에 의해 버팀대가 띠장을 밀게되며, 이에 따라 흙막이판재는 여굴공간으로 이동되어 배면 지반이 침하되게 되는 문제점이 있었다.In addition, as time goes by, the brace is pushed by the pressure of the brace, and accordingly, the retaining plate is moved to the overburden space, and there is a problem in that the back ground is subsided.
