Notes

Unit installation and construction technique of geotextile (the current and strictest) : Geofantex
Installation and building method of geotextile (the most in depth and strictest)
Storage space, transportation and digesting of geotextile
Typically the geotextile roll have to be protected by damage before set up and unfolding. Geotextile rolls should become stacked in a flat place along with no water, as well as the height of the particular stack should not really exceed the peak regarding four rolls, along with the identification film with the roll can be seen. Geotextile proceeds must be protected with opaque components to prevent AS WELL AS aging. During typically the storage process, typically the integrity in the tag and the honesty of the information must be maintained. In the course of transportation (including on-site transportation from the particular material storage internet site to the function site), the geotextile roll must end up being protected from damage. Geotextile rolls that will have been literally damaged must end up being repaired. Geotextiles that are severely used cannot be used. Any geotextile in touch with leaking chemical reactants is not permitted to provide within this project.
Geotextile Transportation
The putting method of geotextile
Use manual rolling; the cloth surface should be flat, together with proper allowance with regard to deformation.
Geotextile stitching: all stitching need to be performed consistently (for example, place stitching is simply not allowed). Before overlapping, the geotextile must overlap at least 150mm. The minimum stitch distance from the particular selvedge (the subjected edge of the particular material) is at at a minimum 25mm. The stitches of the stitched geotextile include the particular one-line and chain stitch method. The thread used with regard to stitching should be a botanical material having a minimum tension greater than 60N, and have chemical substance resistance and AND ALSO resistance equivalent in order to or exceeding that will of geotextile. Virtually any? drop stitches? in the sewn geotextile must be re-sewn in the affected region. Corresponding measures must be delivered to prevent soil, particulate make a difference or foreign make a difference from entering typically the geotextile layer following installation. The towel overlap may be broken down into natural overlap, seam or welded according to the terrain and consumption function.
Laying Non Woven Geotextile
Basic requirements for laying geotextile
The articulation must intersect the slope line; in which it is balanced with the mountain foot or where stress may can be found, the space between the horizontal joint need to be greater compared to 1 . 5m.
Upon the slope surface, anchor one finish of the geotextile, and then put down the coiled material on the slope surface to make sure that typically the geotextile remains within a tight state.
All geotextiles must be pressed with sand bags. The sand bags will end up being used during putting and will be retained until the particular layer of fabric on top of lounging.
HDPE geomembrane
Geotextile Laying
Geotextile laying process requirements
Basic level inspection: Verify if the basic level is flat in addition to solid. If there are international objects, handle these people properly.
Trial laying: Determine the size of the geotextile according to typically the site conditions, and try to put it after slicing. The cutting dimension ought to be accurate.
Check whether or not the width involving the Sarah is definitely appropriate, the overlap should be toned and the tightness need to be moderate.
Setting: Use a hot air gun to bond the particular overlapping areas of the particular two geotextiles, and the spacing of typically the bonding points should be appropriate.
When suturing the overlapping parts, the suture thread should be right and the stitches should be perhaps.
After stitching, check whether or not the geotextile is definitely laid flat and even the availability of defects.
If there is any phenomenon that does not meet the specifications, it should become repaired in moment.
Geotextile Laying process
Self-inspection and fix of geotextile design
All geotextile parts and seams need to be checked. Faulty geotextile pieces in addition to stitches must turn out to be clearly marked on the geotextile plus repaired.
The put on geotextile has to be repaired by laying and thermally connecting small pieces of geotextile. The small bits of geotextile need be at at a minimum 200mm longer than the edge associated with the defect everywhere. The thermal relationship must be firmly controlled to ensure that the geotextile patch and the geotextile are usually tightly combined, and there is no damage to be able to the geotextile.
Before the end involving every day of laying, visually examine the surface regarding all the geotextiles laid that working day to confirm of which all damaged spots have been designated and repaired right away, and make certain that the sleeping surface is free from foreign substances which may cause damage, for example fine needles and small iron fingernails or toenails. Etc ., foreign elements which could cause damage, such as fine tiny needles, small iron nails, etc.
The area material used to fill holes or even cracks should always be the same as typically the geotextile.
The plot should extend at least 30 centimeter beyond the damaged geotextile.
At the particular bottom from the landfill, if the split of the geotextile exceeds 10% associated with the width associated with the coil, the damaged part has to be cut off, and then the two geotextiles must be linked; if the fracture exceeds 10% of the width regarding the coil within the slope, the Typically the roll of geotextile was removed and even replaced with a new new roll.
The particular work shoes used by the structure personnel and the particular construction equipment utilized should not damage the geotextile, plus the construction personnel shall not do things that will may damage the geotextile for the laid geotextile, for instance cigarette smoking or poking the particular geotextile having a well-defined tool.
For your safety of geotextile components, the packaging motion picture should be opened up before laying typically the geotextile, that will be, one roll is laid then one roll is opened. And inspect the look top quality.
