6.2.2 Installation in Flowing Water（e.g. river channel,
reservoir area, etc.）
The water-calming equipments are required.
Method one: Insert a steel tube in the water channel (see Fig. 8).
The steel tube wall should be thicker, and several holes should be made
at different heights on the tube to damp waves and clear the water
pressure influence.
Method two: Superficial burying is better in the sand and stone channel.
(see Fig.9).
