Always design the foundation based on the
site conditions and requirements, and take into account the height of the mast, the area and
weight of the mast and the instruments on it, soil quality, wind load, and other conditions
on the site.
| This document describes a typical example
of a mast foundation.
|CAUTION All design values mentioned in this manual are purely indicative. Vaisala does not take responsibility for their applicability to the area in question.
| In a groundwater area, the
foundation must be deeper or wider.
|CAUTION For the mast base
installation, the soil bearing capacity must be at least 45 kPa
A slab foundation is recommended. If the
site is unsuitable for a slab foundation, choose a different site.
The mast foundation instructions in this
manual apply to both reference calculations when you use one or two sets of guy wires, like
in the examples.
| In Vaisala
documentation, the term guy wire is used to refer to both frangible guyings made of
glass fiber reinforced plastics (GRP) and guyings made of stainless steel.
