Power transmission line iron tower foundation construction method
The invention discloses a power transmission line iron tower foundation construction method. The method comprises the following steps that firstly, construction preparation is conducted; step 2, pit separation measurement; thirdly, a spiral anchor drilling machine is in place; step 4, drilling a spiral anchor; 5, positioning the steel bearing platform; and sixthly, the steel bearing platform is welded and installed. A new iron tower foundation construction scheme is formed, an anchor rod drill bit rotating underground mode is used for changing an original concrete bearing platform mode, then the steel bearing platform is installed, and therefore the method has the advantages of being short in construction period, high in construction efficiency, small in environmental influence and the like, the disturbance degree of a spiral anchor on undisturbed soil in the process of screwing the spiral anchor into the ground is small, and the construction period is shortened. The spiral anchor group and the steel bearing platform are used as a whole in undisturbed soil to jointly resist upward pulling force, downward pressing force and horizontal force, and the settling volume of the foundation is small.
本发明公开了一种输电线路铁塔基础施工方法，包括以下步骤：步骤一：施工准备；步骤二：分坑测量；步骤三：螺旋锚钻机就位；步骤四：螺旋锚钻进；步骤五：钢承台定位；步骤六：钢承台焊接及安装。本发明形成一种新的铁塔基础施工方案，用锚杆钻头旋转入地方式改变原有混凝土承台的方式，然后进行钢承台的安装，从而具有施工周期短、施工效率高、环境影响小等特点，并且螺旋锚在旋拧入地下的过程中对原状土扰动程度小，螺旋锚在原状土中以螺旋锚群和钢承台作为整体，共同抵抗上拔力、下压力和水平力，基础沉降量小。
