Abstract:Taking G40 iron tower foundation construction of Luanhe Power PlantZhouyingzi Substation 220kV double circuit line as example, the construction process of large open well dewatering method was introduced, and relevant calculation verification was given. The large open well dewatering construction method was compared with the traditional well point construction method, and the advantages of the large open well dewatering construction method were pointed out.

Key words: Key words:power transmission line engineering, tower foundation construction, large open well dewatering method, well point dewatering construction method, engineering application
