1. FABRICATE A SEDIMENT BARRIER FROM GEOTEXTILE.
2. FOLLOW DETAIL FOR SEDIMENT FENCE FOR GEOFABRIC
INSTALLATION. REDUCE PICKET SPACIN O 1m CENTRES.

 

    

3. DO NOT COVER THE INLET WITH GEOTEXTILE UNLESS THE
DESIGN IS ADEQUATE TO ALLOW FOR ALL WATERS TO
BYPASS IT.

CONSTRUCTION NOTES

1

FABRICATE A SLEEVE FROM GEOTEXTILE OR WIRE MESH
LONGER THAN THE LENGTH OF THE INLET PIT AND FILL.
WITH 25mm TO 50mm GRAVEL.

FORM AN ELLIPTICAL CRI SECIRCUITION APPROX.
HIGH, 400mm WIDE.

PLACE THE FILTER AT OPENING LEAVING AT LEAST
100mm BETWEEN KERB INLET AND SLEEVE. MAINTAIN
OPENING WITH SPACER BLOCKS.

FORM A SEAL WITH KERB TO PREVENT SEDIMENT
BYPASS.

SANDBAGS FILLED WITH GRAVEL CAN BSTITUTE FOR
THE MESH OR GEOTEXTILE PROVIDED THEY ARE PLACED
SO THAT THEY FIRMLY ABUT EACH OTHER AND
SEDIMENT LADEN WATERS CANNOT PASS BETWEEN.

SEDIMENT FENCE CONSTRUCTION NOTES

1 CONSTRUCTION SEDIMENT FENCES AS CLOSE AS
POSSIBLE TO BEING PARALLEL TO THE CONTOURS OF THE
SITE, BUT WITH SMALL RETURNS. THE CATCHMENT AREA
SHOULD BE SMALL ENOUGH TO LIMIT WATER FLOW IF
CONCENTRATED AT ONE POINT.

2 CUT A 150—mm DEEP TRENCH ALONG THE UPSLOPE
LINE OF THE FENCE FOR THE SOTTOM OF THE FABRIC TO
BE — ENTRENCHED.

3. DRIVE TIMBER STAKES INTO GROUND AT 2.5m.
INTERVALS (MAX) AT THE DOWNSLOPE EDGE OF THE TRENCH.
4 FIX SELF—SUPPORTING GEOTEXTILE TO THE UPSLOPE
SIDE OF THE POSTS ENSURING IT GOES TO THE BASE OF
THE TRENCH. FIX THE GEOTEXTILE WITH WIRE RECOMMENDED
BY THE MANUFACTURER. THE USE OF SHADE CLOTH FOR
THIS PURPOSE NOT SATISFACTORY.

2. JOIN SECTIONS OF THE FABRIC AT A SUPPORT PI
WITH A 150mrm_ OVERLAP.

6. BACKFILL THE TRENCH OVER THE Bi OF THE FABRIC
AND COMPACT IT THOROUGHLY OVER THE GEOTEXTILE.
