Construction method of transmission line in desert area

Abstract

The invention discloses a construction method for a power transmission line in a desert area, which comprises the following steps: building a temporary construction road: transporting ordinary loess or hard soil from the outside to spread on the surface of the road, and using common construction machines such as forklifts to carry out rolling; building an iron tower foundation and Maintenance: After the foundation of the iron tower is well maintained, the transmission tower is assembled by using the method of decomposing and assembling the tower with the suspension and holding poles of the inner cable; Carry out backfilling after the heavy objects; carry out the setting-out and tightening construction of the wires, and complete the erection of the wires and the installation of accessories; Sow psammophyte grass seeds to restore vegetation, and sow grass seeds to restore the original appearance of the construction site. The invention adopts the mode of temporary road construction and making simple gravity ground anchor to improve the degree of mechanized construction, reduce construction risk and ensure construction quality.

Description

technical field [0001] The invention relates to a construction method of a power transmission line, in particular to a construction method of a power transmission line in a desert area. Background technique [0002] In the construction of transmission lines in desert areas, there will be problems such as difficult material transportation, difficult foundation maintenance, ground anchor embedding cannot meet the pullout resistance requirements, grassland vegetation restoration after construction, and backfilling sand layers in desert areas are difficult to fix; However, there are problems such as difficult materials and mechanical transportation, low construction efficiency, inadequate concrete maintenance, large safety risks, high post-line operation and maintenance costs, and serious environmental damage. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a constructio...
