Abstract:In order to solve the problem of engineering materials and construction equipment transportation of high mountain and daling transmission lines, the problem of engineering materials and construction equipment transportation of mountain daling transmission lines is solved by using simple circular cableway transportation method. The results are obtained from the application scope, erection, transportation efficiency, and comparison of transportation costs with traditional human(animal) forces. Under the conditions of high mountains and mountains, The application of simple circular cableway for transmission line materials will be the necessity and inevitable result of restricting the construction of the project. The simple circular cableway transportation method is reasonable in technology, environmental protection, safety and reliability, and completely solves the problem of the installation of materials transportation caused by the laying of trestle roads in some of the tower bases of the mountain and Daling transmission lines. In particular, it provides a guarantee for the solution of the transportation problems of overweight and oversized towers. It not only improves the construction and transportation efficiency, but also achieves good economic and social benefits. It has a high popularization value in the construction of harsh terrain of transmission lines.
