To conform to the construction drawing design for each project, too narrow the number of nodes of the composite membrane laying. Not economically. Regardless of the length of the cross-section, there should be sufficient margin to prevent the tension of the composite geomembrane from being reduced.
 
According to the plan and composite geomembrane width, the number of reduction must be stitched. Draw the cut soil film amplitude number. Draw the clipped soil film amplitude number and then count the bottom. The general inspection method is to observe the material with the naked eye smooth, no harm.
 
If the value displayed by the pressure gauge is still normal, it means that the welding must meet the construction requirements. At the bottom of the formation of blisters, when the reservoir water level drops inflation. It is best to cover the soil with a protective layer of film from one side to the other.
 
Surface cleaning: The foundation surface must be cleaned according to the design requirements. The surface is clean and tight and smooth with rammer or plate. The protective layer of composite geomembrane material must play dynamic compaction dry density, which is more than 1.5, at any time sampling inspection backfill.
