Second part: The preparation of the cash box of the filter
|
|
|
|
|
The bottom of the filter: a floor gone up with boards of
recuperation of 20mm. The settings in blue are achieved with "laths
for roof" treated against the humidity of 35x24mm.
|
Detail of the flooring, one notice a double setting,the vats are conical the small setting has the measurements of the bottom of the vat, the big side is the top of the cans (one differences of + /- 50mm)
|
|
|
|
| Implementation of the senior executive to the same
measurements that the big corresponds the floor. The cans separated by one
"batten" of 24mm |
Not to forget to make the holes in the floor to let
to pass the Back Wash. The shape is a little bizarre, it is to let
to pass the pass partitions with an elbow to 90° of gone up.
|

|
|
There is a view of the returned floor, to leave the place to the pipe of the
back wash and to support the weight of the filter I used small
beams made of wood of 70x40mm.
The 70mm are determined by the height of the pipes of back-wash.
|
Rest now to join the floor and the setting, one
small slope (2cm) is created between the before and the back of the filter (for
the evacuation of the rainwater)
Not to forget to plan the strut for the passage of the pipes
of arrival of water to the level of the amounts. |
|
|
|
|
There is the third and last setting who will only serve has hold the
low of the casing of the filter. He/it won't touch soil for not
to remain in water in case of rain or snow.
|
There is a view on one of the gone up back-wash meadow, the low-down is held
between two supports of the third setting.
|
|
|
|
|
Finish of the base plate on which will rest the filter: a panel of 12mm of
multiplex is put on the small beams of 70mm. |
On the panel of multiplex will be pasted two panels of rigid moss
of 20mm that will assure contact with soil. It is necessary to calculate the
height of the third setting so that he doesn't touch soil when the
filter will be put on the floor. |
