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 (940 pounds-force/ft2). |
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. |
