Reinforced concrete retaining wall with horizontal supporting force provided by anchor cables and construction method of reinforced concrete retaining wall
The reinforced concrete retaining wall comprises a retaining wall body, a cross beam, a supporting column, a fixed pulley, the anchor cable and an anchorage device, the lower end and the upper end of the supporting column are fixed into a soil body and fixed to one end of the cross beam respectively, and the other end of the cross beam is fixedly connected with the upper end of the retaining wall body; inner pipes are fixedly arranged in the retaining wall and the cross beam, one end of the anchor cable is anchored in a soil body below the retaining wall, and the other end of the anchor cable sequentially penetrates through the inner pipes and then is tensioned and locked together with the anchorage device; the anchor cable is in clearance fit connection with the inner pipe; the fixed pulley is rotatably mounted in the retaining wall, and the anchor cable is bridged on the fixed pulley. The invention further discloses a construction method. The anchor cable of the free section is anchored on the bearing plate after passing through the inner pipe and the fixed pulley, and at the moment, the tensioning prestress of the anchor cable at one end of the beam away from the retaining wall is converted into pressure on one end of the beam. The pressure is balanced with the active horizontal pressure of the soil body on the retaining wall, and the horizontal pressure bearing capacity of the retaining wall is improved.
本发明公开了一种由锚索提供水平支撑力的钢筋混凝土挡土墙，包括挡土墙、横梁、支撑柱、定滑轮、锚索和锚具，支撑柱的下端和上端分别固定于土体内和固定于横梁的一端上，横梁的另一端与挡土墙的上端固定连接；挡土墙和横梁内均固定设有内管，锚索的一端锚固于挡土墙下方的土体内，另一端依次穿过内管后与锚具张紧和锁定在一起；锚索与内管之间为间隙配合连接；定滑轮可旋转安装于挡土墙内部，锚索跨接于定滑轮上。还公开一种施工方法。自由段的锚索经过内管和定滑轮后锚固在承压板上，此时在远离挡土墙的横梁一端的锚索的张紧预应力就转变为对该横梁一端的压力。此压力与土体对挡土墙的主动水平压力平衡，提高了挡土墙承受水平压力的能力。
