4.3.3. Workflow with pre-fabricated concrete foundation
Be aware that the position footprint relative to the road is very important
to make sure the pantograph can function optimally.
1. Preparations
Before the pre-fabricated concrete foundation can be installed some measurements have to
be taken into account. The Soil conditions are very important for the function of the concrete
foundation.
Depending of the soil conditions sand settlement can take place. Because of the heavy
construction > 17636.98 lb some preventive actions are advised. The time frame in which the
soil settlement will be elaborated is depending on:
Sand compaction during installation
Pavement around the construction
Wetter conditions (rain, frost, temperature)
Before starting to install the concrete foundation, the pressure of the soil must be measured.
It is advisable to install the concrete foundation on a soil pressure ≥ 100 kPa. If the measured
soil pressure is more than 100 kPa, no soil compact actions has to be taken.
If the concrete foundation will be installed on another ground type than sand (like rock, gravel,
clay or peat), take contact with the ABB Sales department, see Contact information on Page
13 for contact details.
2. Make a hole
Make a hole in the soil on the position were the charging construction will be installed. The
hole must be at least 98.43 x 98.43 Inch (the concrete base plate has a foot print of 94.49 x
