Abstract

The present invention relates to a retaining wall temporary facility wale structure. A product is developed by inserting a hydraulic jack function into the structure. A preload is given to a retaining wall facility to greatly help in maintaining safe facilities. The present invention uses a method of calculating a design axial force for a temporary facility retaining wall in an earth anchor construction method to use a tensioner for each step to fix the temporary facility retaining wall after tensioning in accordance with the axial force to respond to rear soil pressure among present temporary facility construction methods. The method maintains sturdiness and uses the inserted hydraulic jack function in the waling structure to calculate the response axial force in accordance with the depth of each retaining wall facility step to assign a reverse load to the rear soil pressure to fix the structure. Also, the waling structure is maximally elongated to be constructed to greatly reduce loss in steel of a truss (strut) which is a problem at a site.

Description

띠장(보)빔 구조체{BOW BEAM STRUCTURE}STRUCTURE {BOW BEAM STRUCTURE}

본 발명은 흙막이 가시설 시공시 띠장(보)빔구조체에 관한 것으로, 더욱 상세하게는 맞춤 제작한 띠장빔에 역하중잭(jack) 기능을 삽입시켜 본 구조물을 통해 시공의 안전성과 편의성 및 효율성 갖게 하는 흙막이 가시설 시공시 적용 할 수있는 구조체 에 관한 것이다.The present invention relates to a wale (beam) beam structure when constructing temporary retaining facilities, and more particularly, by inserting a reverse load jack function into a custom-made wale beam to have safety, convenience and efficiency of construction through this structure It relates to a structure that can be applied when constructing a temporary retaining facility.

일반적으로 흙막이 가시설은 건축물 지하시설, 지하철, 하수관거 등과 같은 공사시 지반 터파기를 하게 되는데, 이때 흙의 붕괴를 막고 지하 구조물을 설치하기 위하여 가시설 설치를 하게 된다. In general, temporary earth retaining facilities are excavated during construction such as underground facilities of buildings, subways, sewage pipes, etc. At this time, temporary facilities are installed to prevent soil collapse and install underground structures.

이러한 흙막이 가시설은 토사붕괴등 안전성 확보가 중요하므로, 많은량 의 버팀보(트러스). 수직받침보. 수평 간격제등 으로 설치를 하고 있다.For these temporary retaining facilities, securing safety such as soil collapse is important, so a large amount of support (truss) is required. vertical support beam. It is installed with horizontal spacers.

그러나, 버팀보(트러스) 설치를 위한 강제와 경비등이 증가하며, 이는 장비의 지하 굴착시 시설 구조물에 간섭으로 인한 불편함으로 공사기간이 연장되며, 강제의 매립등 손실의 결과를 나타내게 된다.However, the force and cost for installing the brace (truss) increase, and this increases the construction period due to the inconvenience caused by interference with the facility structure during underground excavation of equipment, and results in losses such as forced landfill.

상기와 같이 문제점을 해결하기 위한 본 발명의 목적은 흙막이 가시설 공사시 벽체를 지지하기 위하여 버팀보(트러스)빔 과 세로받침보(매립)빔 설치를 생략함으로서, 자제의 손실과 목적하는 시공의 편의성을 확보할수 있는 흙막이 가시설 시공시 사용할수 있는 견고한 띠장(보)빔 구조체을 제공하는 데 있다.The purpose of the present invention to solve the above problems is to omit the installation of a beam (truss) beam and a vertical support beam (buried) beam to support the wall during the construction of temporary retaining facilities, thereby reducing the loss of self-restraint and the convenience of the desired construction. It is to provide a strong wale (beam) beam structure that can be used in the construction of temporary retaining facilities that can be secured.

상기와 같은 목적을 달성하기 위한 본 발명의 흙막이 가시설 구조체는 공사 순서에 맞추어 수직 천공 후 삽입하는 수직빔; 및 상기 수직빔의 일정간격의 터파기와 토류판 내지는 기타의 방법으로 흙막이 한후 일정 간격에 수직빔 전면에 보빔 (띠장빔)를 설치하게 된다. 이후 본 구조체를 설치, 역하중젝을 삽입 시킨 부재 로서 지하터파기시 단계별 배면토압에 대응하는 견고한 띠장(보)빔구조체를 설치하는 것을 특징으로 한다.Retaining temporary facility structure of the present invention for achieving the above object Vertical beams inserted after vertical drilling according to the construction order; And after digging the vertical beam at regular intervals and retaining the earth using earth plates or other methods, a beam is installed in front of the vertical beam at regular intervals. After this structure is installed, it is characterized by installing a solid wale beam structure corresponding to the back earth pressure in each stage when digging underground as a member with a reverse load project inserted.

상기 구조체를 부착하여 구조체 내부에 삽입되어 있는 유압젝(jack)에 기능으로 외력을 가하여, 시설에 공간을 차단할 수가 있으며 배면 토압에 대응하는 것을 특징으로 한다.By attaching the structure and applying an external force as a function to a hydraulic jack inserted into the structure, it is possible to block the space in the facility, and it is characterized in that it responds to the back earth pressure.

흙막이시설과 터파기시 심도와 넓이에 따라 단계별 배면토압이 다르게 계상되므로 단계별 현장여건에 맞추어 설계축력과 안전율을 고려한 정확한 선행 역하중을 부여하여, 예를들면 어스앵커공법시 단계별 설계축력에 따른 인장력을 부여하고 고정을 시킴으로써 배면토압에 대응하는 것과 같이 견고성을 가진 띠장(보)빔구조체에 유압젝 기능을 삽입함으로서 단계별 필요한 역하중을 부여하여, 고정시킴으로서 안전한 시공을 하게된다.Since the back earth pressure is calculated differently for each stage according to the depth and width of the retaining facility and digging site, an accurate preceding reverse load is given in consideration of the design axial force and safety factor according to the site conditions for each stage. By inserting the hydraulic eject function into the wale (beam) beam structure with rigidity as in response to the back earth pressure by applying and fixing it, the necessary reverse load for each stage is given and fixed, so that safe construction is carried out.

이상 과 같이, 본 발명은 흙막이 가시설 시공시 띠장빔구조체로 시공을 하게 되면 보다 안전하고 계산적 수치에 의한 시공을 할 수가 있으므로, 배면토압에 대응을 하며 그 결과 기존에 설치 되고 있는 버팀보(트러스)빔 설치를 최소화 또는 생략 할수 있으며 버팀보(트러스)빔을 받쳐주는 세로받침빔 설치를 생략할수 있으므로 지하 굴착공간 확보 및 강제 설치의 감소 강제손실(매립)을 막을수 있으며 시설에 대한 안전을 확보할 수 있다.As described above, in the present invention, when constructing a temporary retaining facility with a wale beam structure, it is safer and can be constructed by calculations, so it responds to the back earth pressure, and as a result, the existing brace (truss) beam Installation can be minimized or omitted, and the installation of a vertical support beam that supports the truss beam can be omitted, so it is possible to secure an underground excavation space and reduce forced installation.
