Background
With the rapid development of national economy and the continuous improvement of the living standard of people, power transmission lines, high-speed railways and highways are rapidly developing. Because the power transmission lines, the high-speed railways and the highways are distributed densely and continuously, the parallel and crossed situations are inevitable, the situation that the newly-built lines are crossed with the built corridors often occurs, and particularly the problem of continuous drilling crossing when one side of a newly-built power transmission line tower drills and the other side of the newly-built power transmission line tower drills is more and more common. According to the regulation requirements, it is suitable to cross a line with a lower voltage grade and drill a line with a higher voltage grade, so that the situation that a newly-built power transmission line crosses a high-speed railway and a highway first and then drills an established power line is common.
In practical engineering, for the situation that a newly-built single-circuit transmission line firstly crosses a high-speed railway or a highway and then drills an already-built power line, the following measures are generally adopted:
(1) adjusting the path of the newly-built line, so that the newly-built line crosses the high-speed railway or the highway in different sections and then drills over the built power line, and the scheme needs to coordinate a government planning department to re-repeat the path, so that the difficulty is high; meanwhile, the scale of a newly-built line is increased, and the engineering investment is increased.
(2) By increasing the built line with higher voltage level or reducing the built line with lower voltage level, the scheme can cause the built line to have power failure for a long time, the influence surface is larger, and the line construction cost is increased.
(3) The mode that the overhead cable crosses over the high-speed railway or the highway and the cable crosses over the built power line is adopted, the cost of the cable entering the ground is high, and the engineering investment is increased.
In summary, the above scheme is difficult to construct and high in comprehensive cost, and is not beneficial to engineering implementation.
