Description

본체로 이용하는 지하 연속벽 축조에서의 콘크리트 타설 방법Concrete pouring method in underground continuous wall construction

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제 1 도는 엘레멘트 굴삭후 본 발명에 따른 불투수성 포대의 사용을 설명한 도면.1 illustrates the use of an impervious bag according to the invention after element excavation.

제 2 도 포대 내부에 철근을 넣고 콘크리트를 타설하는 방법을 설명한 도면.2 is a view for explaining how to put the reinforcement in the bag and cast concrete.

Claims (4)

벤토나이트계 또는 폴리머계로 이루어진 안정액을 사용하여 각 엘레멘트(element)를 굴삭해 굴삭부를 형성하고 ; 굴삭부의 크기와 동일한 형태의 유연하고 활동(滑動)이 가능한 PP, PE 또는 RVC 포대와 같은 불투수성 포대를 굴삭부 상부에 설치하고 ; 배출관을 통해 굴삭부 내의 안정액 굴삭부 저면의 슬라임을 배출시키면서 배출되는 안정액의 양과 동일한 양의 약제를 포대에 넣어 포대가 안정액의 배출과 연동되어 굴삭부 벽면을 따라 원활히 내려가도록 하고 ; 배출관을 인양하고 포대 내부에 조립된 철근을 넣은 다음 콘크리트를 타설하고 ; 콘크리트가 굴삭부 저면에 적당량 채워지면 포대 저면에 설치된 수밀성 개구부를 개방하여 콘크리트가 저면의 암반과 밀착하여 일체화되도록 하고 ; 콘크리트를 계속 타설하면서 이와 동시에 포대를 굴삭부 밖으로 인발하여 타설된 콘크리트가 굴삭부 벽면과 밀착되도록 하는 단계를 이루어짐을 특징으로 하는 본체로 이용하는 콘크리트 지하 연속벽 축조에서의 콘크리트 타설방법.Excavating each element by using a stabilizer made of bentonite or polymer to form an excavation portion; An impervious bag, such as a flexible, movable PP, PE or RVC bag, of the same size as the excavator, is installed on the top of the excavator; The lubricating agent discharges the slime at the bottom of the stabilizer in the excavating portion through the discharge pipe, and puts the same amount of medicine into the bag so as to smoothly descend along the wall of the excavator in conjunction with the discharge of the stabilizer; Lift the discharge pipe, put the assembled reinforcing bar inside the bag and cast concrete; When the concrete is filled in the bottom of the excavation portion, the watertight openings provided in the base of the bag are opened to allow the concrete to be intimately integrated with the rock on the bottom; A method of placing concrete in a continuous concrete wall construction using a main body, characterized in that the step of continuing to cast concrete and at the same time draw the bag out of the excavation to ensure that the concrete is in close contact with the wall of the excavation. 제 1 항에 있어서, 포대의 내부에 넣은 약제가 주제인 폴리아크릴아미드 75~85중량%와 N-알킬 치환 아크릴아미드 또는 N,N-비스(카복시메틸)아크릴아미드와 같은 이의 유도체나 가수분해물, 또는 이를 주성분으로 한 공중합물이나, 셀롤로스 고분자물에서 1~2종을 배합한 액상의 배합물인 재료분리 방지제인 방법.2. A pharmaceutical according to claim 1, wherein the drug contained in the bag is 75 to 85% by weight of the main polyacrylamide and derivatives or hydrolyzates thereof such as N-alkyl substituted acrylamide or N, N-bis (carboxymethyl) acrylamide, Or a material separation preventing agent which is a copolymer containing the same as a main component or a liquid formulation in which 1-2 kinds of cellulose polymers are blended. 제 1 항에 있어서, 굴삭부내 콘크리트 타설시 불투수성 포대를 굴삭부 밖으로 인발하는 대신에 굴삭부내에 방치된 상태로 하여 콘크리트를 타설함으로써 방수막의 역할을 하도록 하는 방법.The method according to claim 1, wherein when placing concrete in the excavated portion, the impermeable bag is left in the excavated portion instead of drawing out of the excavated portion to cast the concrete to serve as a waterproof membrane. 제 1 항에 있어서, 불투수성 포대 내부에 약제를 투입하고 콘크리트를 타설하는 대신에 불투수성 포대 내부에 물을 투입하고 수경성 콘크리트를 타설하는 방법.The method according to claim 1, wherein water is poured into the impermeable bag and the hydraulic concrete is poured instead of pouring the medicine into the impermeable bag and placing the concrete. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
