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.|
|CAUTION Always consult a local civil engineer about the foundation design and to find out about the soil and frost conditions in the area. When the soil is frost-susceptible, always use proper insulation.|
| In an area with frost-susceptible
soil, the foundation must reach below the soil frost penetration depth or sufficient
| 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.
