4.2.3 Foundation Requirements
A foundation is required only in the base support-mounting scenario.
Before installation, build concrete platforms and trenches on the selected ground.
The foundation construction requirements are as follows:
● The dimensions of the foundation shall meet the installation and load-
bearing requirements of the base support.
● The foundation must be above the highest water level and snow depth of the
local area in history and at least 300 mm above the ground.
● The average foundation strength shall exceed 100 kg/cm
2
.
● The levelness error of the contact surface between the foundation and base
support shall be less than 5 mm. During construction, consider the soil
compaction factor to avoid subsidence, and periodically measure the
levelness. If the levelness does not meet the requirement due to subsidence,
use leveling spacers.
● Cables are routed from the bottom of the base support. Therefore, you shall
bury cables underneath before installing the base support.
● The inner diameter of the protective tube shall be greater than or equal to 1.5
times the outer diameter of the cable (including the protective layer).
● Construct drainage facilities based on the local geological conditions and
municipal drainage requirements to ensure that no water will accumulate at
the equipment foundation. The foundation construction must meet the local
drainage requirements for the maximum historical rainfall. The drained water
must be disposed of in accordance with local laws and regulations.
● After the foundation is excavated, prevent water from entering the
foundation. If water enters the foundation, excavate and rell the aected
parts.
● Cable trenches (if any) shall not be used for drainage. Fire retardant sealing
shall be implemented at cable holes (such as holes through partition walls
and oors).
