摘要
On the prepared substrate (1,2) of waste disposal site an impermeable membrane (2) is laid. On top of the membrane gravel or a similar medium is formed into a drainage layer. The drainage medium is contained within sacks (3) or similar type bagging. The drainage layer has a series of collection pipes run into it which lead to a holding tank. USE/ADVANTAGE - Sacks can be used to form embankments and provide reinforcement where strong flow can cause damage. Also, holding gravel in sacks reduces likelihood of gravel puncturing waterproof membrane.
