单束张拉和多束张拉工艺在斜坡治理中的联合应用

Combined Application of Single Beam Tensioning and Multi-beam Tensioning Technology in Slope Treatment

格构梁的锚索张拉大多采用多束张拉工艺。在甘肃陇南消防支队后山不稳定斜坡锚索格构梁防护施工中,遇到钢绞线外露工作长度不足,多束张拉难以进行的问题。提出了单束张拉工艺与多束张拉工艺联合应用治理不稳定斜坡的方案。详细介绍了施工工艺以及治理效果。

Multi beam tensioning technique is mostly adopted for the tensioning of anchor cables of lattice beams.In aprotection construction of the unstable slope cable lattice beam in Longnan of Gansu,it was difficult to carry out multi-beam tension due to the insufficient working length of the strand.A treatment scheme of combined application of single-beam tension technology and multi-beam tension technology is put forward.The construction technology and treatment effect are introduced in detail.
