CONSTRUCTION METHOD FOR RAILWAY BRIDGE
The present invention provides a construction method for a railway bridge comprising: a separation member preparing step of preparing a separation member (110) in which a waterproof part (111) formed by an asphalt mixture and a fabric part (112) formed by a geotextile material are formed in a stacked structure; a protection concrete deposition step of forming a protection concrete layer (PCL) (10) by depositing concrete on the upper surface of a bridge deck (1), and forming a plurality of shear keys (11) protruding upwards in a line along a longitudinal direction; a separation member installation step of affixing the waterproof part (111) of the separation member (110) to an upper portion of the protection concrete layer (10) to form a separation layer (100); and a track concrete deposition step of depositing concrete on the upper surface of the fabric part (112) of the separation member (110) to form a track concrete layer (TCL) (20). The separation member is not easily deformed or damaged during construction. The separation member is easily folded to install the shear keys to be completely closed. The weight of the separation member is small to obtain excellent constructability.
본 발명은 아스팔트 혼합물에 의해 형성된 방수부(111)와, 토목섬유 재질에 의해 형성된 직물부(112)가 적층구조로 형성된 분리부재(110)를 준비하는 분리부재 준비단계; 교량 상판(1)의 상면에 콘크리트를 타설하여 보호콘크리트층(PCL)(10)을 형성하되, 상측으로 돌출된 복수의 전단키(11)가 길이방향을 따라 열지어 형성되도록 하는 보호콘크리트 타설단계; 상기 보호콘크리트층(10)의 상부에 상기 분리부재(110)의 방수부(111)를 접착하여 분리층(100)을 형성하는 분리부재 설치단계; 상기 분리부재(110)의 직물부(112)의 상면에 콘크리트를 타설하여 도상콘크리트층(TCL)(20)을 형성하는 도상콘크리트 타설단계;를 포함하는 것을 특징으로 하는 철도교의 시공방법을 제시함으로써, 시공 중 분리부재의 변형이나 손상이 쉽게 발생하지 않고, 분리부재의 접힘가공이 용이하여 전단키를 완전히 폐쇄하도록 설치할 수 있으며, 분리부재의 중량이 작아 우수한 시공성을 얻을 수 있도록 한다.
