Transport and lifting

 

Transport : the réhausses incorporating pre-assembled filtration systems. For reasons of congestion during transport, they are in position on the equipment during installation.

 Lifting : lifting operations are réaliséees with slings arranged according to the schema above top

 



LAYING PIPELINE

 

Under green space, non-napp

(e) table and without risk of rolling load

 

The lid of the standard spacers is located at the field level natural (or embankment above the tank maximum 800 mm). Ask the apparatus using slings on a background of search stabilized (of sand, for example).

 

 

-Ask the device on a stable and horizontal search background (bed of compacted sand)

-Filling up to half of the body with a mixture sand / gravel 10-14 nursing closed spaces to ensure a good base of the tank.

-Proceed by successive layers (300 mm max)

-Stabilize the embankment watering between each layer (not mechanical compaction gear)

-Put the tub water simultaneously to balance level of embankment and domestic water level

-Filling the upper part of the tank with gravel 10-14

-Set up the filter tensioners and connect the lines to the network

-Complete the filling to the natural ground



Off-standard conditions

 

-Height of embankment > 800 mm above the apparatus

-Risk of exposure to rolling loads

-Presence of groundwater (with Max level remaining essential < 50% of the height of the body)

 

Conditions of manutenttion and embankment remains the same but it is imperative to achieve a slab of distribution over the device. This slab will role to protect the device against too large embankment charges. Presence of water table it will also ensure the ballast of the apparatus.

 

 

Attention: the mass of ballast for groundwater must be greater than the thrust of archimède
