Cantilever type retaining wall instability reinforcing method
The invention discloses a cantilever type retaining wall instability reinforcing method, and particularly relates to the technical field of retaining wall reinforcing, which comprises the following steps: digging a foundation soil layer at a retaining wall reinforcing position by using two excavators when a foundation is removed, and arranging vertical pilasts at intervals of 4m from the end part of a masonry retaining wall when vertical pilasts are built, during stranded wire reinforcement, an operator supports the lower portion of a ring beam, a side formwork and a pilaster formwork, the steel strands are all arranged in the direction of the ring beam during holing and laying, a cushion layer is poured when the position of an anchorage pier is determined, anchorage pier reinforcing steel bars are installed during anchorage pier reinforcing steel bar implantation and pouring, and during maintenance, a mobile phone needs to be used for photographing and uploading each time of watering. A plurality of ring beam steel bars and other steel bars for binding a vertical pilaster are arranged outside the steel bars in a sleeving manner, so that the transverse and longitudinal steel bars form an integral vertical stress column, transverse and longitudinal multi-node stress support is performed on the cantilever type retaining wall channel, internal steel wires are wound and fixed after support, the reinforcing support force is larger, and the reinforcing stability is better.
本发明公开了一种悬臂式挡土墙失稳加固方法，具体涉及挡土墙加固技术领域，包括清除基础时利用两台挖机对挡墙加固位置的基础土层挖平，竖向壁柱建造时在砌体挡土墙从端部开始每隔4m设置一道竖向壁柱，绞线加固时操作人员将支设圈梁下部、侧面模板及壁柱模板，开洞铺设时将钢绞线沿着圈梁方向全部布设，锚墩位置确定时浇筑垫层，锚墩钢筋植入浇筑时安装锚墩部位钢筋，养护时每次浇水需要用手机拍照上传。本发明在钢筋的外部套装上多个圈梁钢筋，绑扎竖向壁柱的其他钢筋，使得横向、纵向钢筋成为一个整体的竖向受力柱，对悬臂式挡土墙渠道横纵多节点受力支撑，支撑后内部钢丝缠绕固定，加固支撑力更大，加固稳定性更好。
