Ultra-short anchor cable compensation tensioning construction method
The invention relates to the technical field of bridge construction, in particular to an ultra-short anchor cable compensation tensioning construction method. Comprising the steps that S1, firstly, an anchor cable penetrates through a pre-buried corrugated pipe, then a steel base plate penetrates through the anchor cable to make contact with a reinforcing layer of a bridge, then a first anchorage device, a gasket, a jack and a second anchorage device are sequentially installed on the anchor cable, and meanwhile conical clamping pieces are installed in the first anchorage device and the second anchorage device; and S2, the jack drives the second anchorage device to move outwards, and tensioning construction of the anchor cable is completed. According to the compensation tensioning construction method for the ultra-short anchor cable, in the tensioning process of the anchor cable, the tensioning speed can be effectively guaranteed, and then the phenomenon that the anchor cable is fractured due to the fact that the tensioning speed is too high is avoided, and the situation that when the tensioning speed is low, the time needed by tensioning is long, the construction period of the device is long, and the tensioning work of the device is not facilitated is avoided.
本发明涉及桥梁施工技术领域，具体涉及一种超短锚索补偿张拉施工方法；包括，S1：首先将锚索穿过预埋好的波纹管，然后将钢垫板穿过锚索，使其与桥梁的加强层接触，然后在锚索上依次安装第一锚具、垫片、千斤顶以及第二锚具，同时在第一锚具和第二锚具的内部安装有呈锥形的夹片；S2：通过千斤顶带动第二锚具向外移动，完成锚索的张拉施工。该超短锚索补偿张拉施工方法，在锚索张拉的过程中，可以有效的保证张拉的速度，进而避免张拉速度过快锚索出现断裂的现象，而张拉的速度较慢时，会出现张拉需要的时间较长，致使装置的工期较长，进而不利于装置的张拉工作。
