Embodiment 1
[0029] Embodiment 1: as figure 1 As shown, a structure for preventing the cement rods of transmission lines from pulling up includes cement rods 1, metal rings 2, metal wires 6, waste tires 8 and waste hubs 9. The waste tire 8 and the waste wheel hub 9 are co-installed and placed horizontally, the cement rod 1 is vertically arranged above the waste wheel hub 9, and the steel bar at the bottom of the cement rod 1 is welded to the contact part of the waste wheel hub 9, and a metal ring is set on the top of the cement rod 1 2. Several tensioned metal wires 6 are arranged between the metal ring 2 and the used wheel hub 9, and the several metal wires 6 are evenly distributed. One end of the metal wire 6 is welded to the edge of the waste wheel hub 9, and the other end is welded to the metal ring 2. The metal ring 2 is located above the ground surface. The cement pole 1, waste tires 8 and waste wheel hub 9 below the metal ring 2 are all buried in the The layer of soil below the sur...
Embodiment 2
[0034] Embodiment 2: a kind of construction method that prevents the cement pole of power transmission line from pulling up the structure, it comprises the following steps:
[0035] (1) dig a cement rod pit at the buried cement rod 1 position, and the depth of the cement rod pit is greater than the thickness of the permafrost layer 5;
[0036] (2) The waste tire 8 that is not inflated and the waste wheel hub 9 are installed in cooperation and placed horizontally on the bottom of the cement rod pit;
[0037] (3) set the metal ring 2 on the cement rod 1, and fix the metal ring 2 on the cement rod 1;
[0038] (4) Cement rod 1 is vertically erected in the cement rod pit, and the steel bar at the bottom of the cement rod 1 is welded together with the waste wheel hub 9 contact parts. At this moment, the metal ring 2 is above the horizontal plane;
[0039] (5) one end of several metal wires 6 is fixed on the edge of the waste wheel hub 9 at equal intervals respectively, and the othe...
