Constructing 500-Kv Transmission Lines on a Swampy River Flood Plain (Sooruzhenie Linii 500-Kv V Zabolochennoi Poime Reki)
In the USSR, a 500-kv transmission line was constructed across the swampy flood plain of a river located in a severe climate area. The design length of the span was 410 m. The intermediate towers were erected on islands of imported soil, built up above flood level and sown with grass to prevent wind erosion. The 1:2 slopes of the island, sodded to prevent water or ice damage, continue beyond swamp level as clay-cement cutoffs. The heavy construction work was done in the winter since the swamp was impassable to heavy equipment at any other time. A foundation of precast footings was constructed on reinforced concrete piles, vibro-driven deep into the subsoil. The piles were interconnected just below swamp level by a monolithic, frost-resistant, reinforced concrete grillage foundation. The reinforcing mesh of the grillage was welded to the longitudinal reinforcement of the piles before concreting. This type of foundation is recommended for 330- to 750-kv transmission lines crossing swampy areas. (Author)
