Construction and laying of geotextile maintenance
Geotextile laying process, storage, transportation and handling of geotextiles
Geotextile rolls should be protected from damage before installation and unfolding. Geotextile rolls should be stacked in a flat place that does not accumulate water. The stack height should not exceed the height of four rolls, and the identification piece of the roll can be seen. Geotextile rolls must be covered with opaque material to protect against UV aging. During the storage process, the integrity of the label and the integrity of the data must be maintained.
Geotextile rolls must be protected from damage during transportation (including on-site transportation from material storage to the work site).
Geotextile rolls that are physically damaged must be repaired. Geotextiles that are severely worn cannot be Use. Any geotextile that has come into contact with leaked chemical reagents is not allowed to be used in this project.
. Geotextile laying method
The surface of the artificial rolling cloth must be smooth, and an appropriate allowance for deformation should be left.
The installation of wire or short-wire geotextiles usually uses several methods: overlapping, stitching and welding. The width of stitching and welding is generally upper, and the overlap width is generally upper. Geotextiles that may be exposed for a long time should be welded Or stitching.
Sewing of geotextile
All stitching must be done continuously (for example, point stitching is not allowed). Geotextiles must overlap a minimum before overlapping. The minimum sewing needle distance is from the selvage edge ( The exposed edge of the material) is at least.
Sewn geotextile seams most include row and line lock chain stitches. The thread used for suturing should be the minimum tension exceeding the resin material and have a connection with the geotextile. Equivalent or exceeded chemical resistance and UV resistance.
Any missing stitches on the sewn geotextile must be re-sewn at the affected location.
Appropriate measures must be taken to avoid post-installation , soil, particulate matter or foreign matter enters the geotextile layer.
