        geotextile experts provide detailed filament geotextile construction steps 138~5349~3279 Yang Hongxia. Filament geotextile, polyester filament geotextile, yarn singeing geotextiles, nonwoven geotextile specifications! Geotextiles laying facilities engineering program and process of
. Storage, transportation and processing of geotextile
the geotextile volume in the installation before spreading to avoid damage. The geotextile volume should be piled up in no water after formation, high pile of not more than four volumes of height, and can see the identification sheet roll. The geotextile volume must use the opaque material covered with anti ultraviolet aging. In the process of storage, to maintain the integrity and the integrity of information label.
in the transport process (including the site from the material storage to the work of the transport), geotextile volume must avoid damage.
by physical damage to the geotextile volume must repair. By geotextile can badly worn use. Any contact to the leakage of chemical reagents geotextiles, used in this project is not allowed.
two. The method of laying geotextile:
2.1 using artificial rolling shop; cloth should be smooth, and keeping proper deformation allowance.
2.2 filament or staple fiber geotextile installation methods, usually welded lap suture and. Suture and weld width is generally more than 0.1M, lap width is generally more than 0.2M. The possible long-term exposure of geotextiles, should be welded or suture.
2.3 of geotextiles suture
all suture must be continuous (e.g., stitch is not allowed). In the overlap before the geotextile must overlap at least 150mm. The minimum distance selvage stitches (material exposed edge) is at least 25mm. Geotextile
sewn seams most consists of 1 lines and line locking chain stitch. Suture line should be used for resin material as the minimum tension of more than 60N, and with geotextile is equivalent to or beyond the resistance to chemical corrosion and anti ultraviolet ability.
any sewn on the geotextile "drain pin" must be in the affected local re seam.
must take corresponding measures to avoid after installation, soil, particulate matter or foreign substances into the geotextile layer. Overlapping
cloth can be divided into natural lap seam welding, or according to the terrain and the use function.
2.4 in the process of construction, above the geomembrane geotextile uses natural overlap, or hot air welding seam with geomembrane upper geotextile. Hot air welding method is connected with the first filament geotextile, i.e. using a hot-air gun two pieces of cloth of connection moment high temperature heating, the part reaches the melting state, and immediately the use of certain external forces firmly bonded together. In wet weather can not be carried out (Yu Xuetian) hot sticking connection, geotextile should adopt another method of suture connecting method, namely using special sewing machine for a double stitch suture line connection, and the use of anti chemical uv.
suture the minimum width of 10cm, natural lap width is 20cm, the minimum width of 20cm hot air welding.
2.5 for sewing, should use quality and earthwork cloth the same suture, suture to adopt anti chemical damage and UV irradiation ability stronger material.
2.6 of geotextiles laying is completed by the site supervision engineer approval laying geomembrane.
2.7 geomembrane geotextile geomembrane is in by the party, supervision after the approval of laying ibid. The layers of the
2.8 of geotextiles celebration numbered TN, BN.
2.9 film on soil under two layers of cloth should be in the position of the anchoring slot with geomembrane together into the anchorage slot.
three. The basic requirements of laying geotextile:
    a, seam must intersect with the line of slope; and the existence of stress place toe balance or may, horizontal joint distance must be greater than 1.5m.
    B, on the slope, anchoring one end of geotextile, then roll to be laid down to ensure slope geotechnical cloth taut state.
    C, all of the geotextile are required to use sandbag pressing, sand bag will be used during the laying period and retained to the laying of the top layer material.
