4. The concrete works can be started at this point. First the area around the installation
pipe is concreted, where the pipe must remain accessible after the concrete works are
finished.
5. Once the concrete reaches the level of the frame, the concrete works continue through
the upper opening of the underground anchoring element, where the installation pipe is
placed. The entire space inside the frame must be filled with concrete. In the case of low
temperatures, the concrete must contain anti-icing additives,
6. The next step is precise levelling of the foundation and the concrete around the frame,
where the finishing tiles will be placed. Precise levelling of the underground anchoring
element is important for later installation of the charging station. After the construction
of the foundation is finished, the charging station can be aligned only with the use of
washers, placed on the bolts of the underground anchoring element,
7. The concrete must be left to dry for at least 48 hours (two days) before the cables are
inserted into the foundation and the charging station is installed on the foundation.
4.4 Installation of safety arches
The charging station manufacturer supplies optional safety arches. The safety arches have a
double function:
• they prevent mechanical damage to the charging station which may result from
collisions with vehicles, and
• they enable bikes and scooters to be chained to the arches while charging.
The manufacturer normally supplies a set of safety arches (1 or 2 pieces), which are installed
either at both sides of the charging station (2 arches) or in front of the charging station (1 arch).
If safety arches are added to the charging station, the foundation needs to be prepared in
advance, to add the safety arches to the same foundation as for the underground anchor.
4.4.1 Excavation and foundation construction for safety arches
If safety arches are added to the charging station, the foundation needs to be enlarged
accordingly (with the minimum dimensions of L: 80 cm x W: 50 cm x D: 60 cm).
