BOLLARD LAYING PROCEDURE
Proceed with the realization of the drain of the
rainwater through the lay of a PVC pipe with
100mm diameter. This pipe must be connected
to the sewer system or in alternative to a well
equipped by an emptying system with a greater
depth.
Insert gravel with grain 22/32 mm diameter and
220m height. In order to avoid “retreats of settling”,
it is advisable to compact the gravel.
Insert a geotextile layer (gr. 300) on the compacted
gravel.
Put the PVC pipe (diameter of 100 mm and length
200mm) in the middle of the dig on the geotextile (the
PVC pipe is necessary for the passage of the rain-water).
The size “ h ” are very important to ensure
that the formwork protrudes 20mm from the
trampling line.
