摘要

The heavy weight foundation (10) has a concrete or steel structure that is provided with a base (16), side walls and a ceiling (18), where a shaft for the tower of a wind turbine is arranged on the ceiling. The lowermost layer of the base has a filter characteristic that is designed so that pore water is entered in a filter layer (44) and the solid particles are held. Multiple channels of small diameter are arranged in a distributed manner in the concrete or steel structure to connect the filter layer with the upper side of the ceiling.
