Background
The electric power concrete pole is an electric power pole tower made of concrete and steel bars, and is also called an electric pole, and is used for supporting an overhead power line; in order to adapt to social development, the investment strength of the power distribution network cost is continuously increased in recent years in the power industry, and the development of economy and society is hoped to be fully matched, but because the development speed of power engineering construction is high, a plurality of electric poles left by old engineering are left in situ, so that the environment is attractive, the users go out, and even accidental injury is caused to people going forward and backward. In order to avoid unnecessary damage caused by the waste electric poles, the power supply department arranges for batch and comprehensive dismantling of the left-over waste electric poles.
In the traditional construction of dismantling waste electric poles, a fixed derrick mast is mostly adopted for pulling out and falling down the electric pole, and the pulling out of a concrete electric pole is a special operation of line construction. Before construction, special construction design and technical measures are required to be carried out according to the conditions of the electric pole structure, topography, geology, machines and equipment and the like. This is a relatively dangerous and rarely used mode of operation, and therefore must be acted upon by an experienced power delivery technician. The construction scheme is fully researched before operation, and construction is performed according to a specified operation procedure so as to prevent errors. Before the pole is released, a construction scheme is determined according to pole type characteristics and topography conditions on the basis of field investigation, technological designs and technical measures are written, tools and tools used for dismantling the concrete pole and operation processes are complex, and dismantling difficulty is high.
Meanwhile, in the dismantling process, waste wires are still bound on a plurality of electric poles, the wires give certain tension to the electric poles, rust aging phenomena of cold-drawn steel bars inside the electric poles are caused by long-term weathering, the surface cannot see defects, the cold-drawn steel bars inside the electric poles can be completely corroded, and the electric poles are fixed by the tension. Because the tension of the upper wire is maintained stable when the pole is old and depends on the whole, when a worker releases the wire in the pole climbing operation, the pole loses the support of the force of the wire and is in an unsafe working state, the situation of breaking the pole is easy to occur, and finally, the casualties of the worker are caused.
