Deformation correcting and resetting method for bank wall of river levee channel revetment
The invention relates to the technical field of river embankment channel deformation repair, in particular to a river embankment channel revetment bank wall deformation deviation rectifying and resetting method which specifically comprises the following steps that the inclination deformation state of an embankment channel revetment bank wall is surveyed; according to an investigation result, if the displacement of the revetment wall deviating from the horizontal direction does not exceed 50cm, a specific pressure-bearing type bag type expansion anchor cable counter-force deviation rectifying and resetting construction scheme is designed in combination with the type of a channel revetment wall structure (a retaining wall or a row pile); according to the deviation correction design scheme, punching is conducted at the position, close to the top end, of a revetment wall (1/3 of the upper portion of a retaining wall or 1/2 of a pile body top beam), and pressure-bearing bag type expansion anchor cables are constructed. The problem of deformation and failure of the river levee channel revetment can be solved in time, the inclined channel bank wall is reset by applying tensile force through the anchor cable, then the inner side of the bank wall is excavated, a soft soil layer is taken out, soil backfilling is conducted again, the construction period is short, cost is low, and meanwhile the method has the advantages of being safe, reliable, high in applicability and large in application prospect.
本发明涉及河堤航道变形修复技术领域，具体为一种河堤航道护岸岸墙变形纠偏复位方法，具体方法包括如下步骤：勘察堤防航道护岸岸墙的倾斜变形状态；根据勘察结果，如果护岸岸墙偏离水平位移不超过50cm时，结合航道护岸岸墙结构(挡土墙或排桩)类型设计具体承压型囊式扩体锚索反力纠偏复位施工方案；根据纠偏设计方案，在护岸岸墙(挡土墙上方1/3或桩体冠梁1/2处)处靠近顶端方进行打孔并施工承压型囊式扩体锚索。本发明能及时解决河堤航道护岸的变形失效问题，通过锚索施加拉力使倾斜的航道岸墙复位，然后挖空岸墙内侧取出松软土层后重新进行土壤回填，施工周期短，成本低，同时具有安全可靠、适用性强、应用前景大的特点。
