RETAINING WALL CONSTRUCTION METHOD USING BACKWARD TENSION
The present invention relates to a cutting retaining wall for protecting a road and various facilities by preventing earth and stone generated due to cutting and crushing from flowing inside. An anchor unit (30) built on a cutting unit and the rear surface of a wall body (100) of the retaining wall is connected by a timber (20) which is released and in which an expansion unit (21) is formed. As the cutting is performed, a mounding unit is formed in the rear part of the wall body (10), and the expansion unit (21) is contracted so that the wall body (10) of the retaining wall is extended to the cutting unit. Therefore, the cutting retaining wall can efficiently bear an external force on the wall body (10), generated due to a soil pressure of a rearward mounding unit and a ground contact pressure of equipment. The cutting retaining wall can efficiently improve a support force of the wall body (10) of the cutting retaining wall by having a simple structure. Even if various external forces such as the soil pressure of the rear surface due to the inflow of the cut soil and mounded soil for a work are applied, the cutting retaining wall can solve a problem of an existing construction method for a cutting retaining wall wherein securing of sufficient stability is neglected due to a property of a temporary facility.
본 발명은 절취 및 파쇄 등에 의하여 발생된 토석의 유입을 차단하여 도로 및 각종 시설물을 보호하는 절토 방호벽에 관한 것으로, 방호벽의 벽체(10) 배면과 절토부에 구축된 정착부(30)를 신축부(21)가 구성된 이완상태의 선재(20)로 연결하고, 절토가 진행됨에 따라 벽체(10) 배후부에 성토부가 형성되면 신축부(21)를 수축하여 방호벽 벽체(10)를 절토부측으로 인장함으로써, 배후 성토부 토압 및 장비 접지압으로 인하여 유발되는 벽체(10) 전도측 외력에 효과적으로 저항할 수 있도록 한 것이다. 간소한 구성으로도 절토 방호벽 벽체(10)의 지지력을 효과적으로 증대할 수 있는 발명을 통하여, 절취 토사의 유입 및 작업용 성토 등으로 인한 배면토압을 비롯한 다량한 외력이 작용함에도 불구하고 가설구조물의 특성상 충분한 안정성 확보가 등한시되었던 종래 절토 방호벽 시공방법의 폐단을 타파할 수 있다.
