|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.|
|CAUTION For the mast base installation, the soil bearing capacity must be at least 45 kPa (940 pounds-force/ft2).|
In a groundwater area, the foundation must be deeper or wider.
In an area with frost-susceptible soil, the foundation must reach below the soil frost penetration depth or sufficient foundation depth.
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.
|This document describes a typical example of a mast foundation.|
