Pre-stressed anchoring type sheet-pile wall in fill area and construction method of pre-stressed anchoring type sheet-pile wall
The invention relates to a fill area pre-stressed anchoring type sheet-pile wall which comprises a slope body, piles, crown beams, breast boards and anchor cables, the slope body is provided with a step-shaped excavation face, anchor cable hole channels are pre-embedded in the piles in the length direction of the piles at intervals, steel bars are pre-embedded in the piles in the length direction of the piles at intervals, the piles are arranged on the front side of the step-shaped excavation face, the crown beams are arranged on the tops of the piles, and the breast boards are arranged on the top beams. The soil retaining plate is hung on the pile side; according to the method, the reinforced concrete beams are adopted for protection outside the anchor cables in the backfill area, the vertical load of the backfill soil body is borne through the reinforced concrete beams, the anchor cables cannot settle along with consolidation and settlement of the backfill soil body, and the situation that the anchor cables deform and break when the stress exceeds an allowable value due to excessive settlement of the backfill soil body is avoided.
本发明涉及一种填方区预应力锚拉式桩板墙，包括坡体、桩、冠梁、挡土板和锚索，所述坡体设置有台阶状开挖面，所述桩沿其长度方向间隔预埋锚索孔道和沿其长度方向间隔预埋钢筋，所述桩设置在台阶状开挖面前侧，所述冠梁设置在桩顶，所述挡土板挂在桩侧；本发明，回填区锚索外采取钢筋混凝土梁保护，通过钢筋混凝土梁承受回填土体竖向荷载，使锚索不会因回填土体固结沉降而随之沉降，避免锚索因回填土体沉降过大导致锚索变形、应力超过允许值断裂。
