Ukusetshenziswa kwe-Filament Geotextiles ku-Railway Engineering

owaziwa kakhulu ukusetshenziswa kwe-filament geotextile emigwaqweni emikhulu.Eqinisweni, ibuye isetshenziswe kabanzi kubunjiniyela besitimela.Ngaphezu kwalokho, izinto zokwakha ze-filament geotextile bezilokhu zaziwa kakhulu ezinhlelweni zobunjiniyela bezitimela.Ukucaciswa kwe-geotextile kuzonqunywa esizeni, futhi imfuneko yekhwalithi akufanele ibe ngaphansi kuka-200g/㎡.Isitifiketi sokulethwa sizohlolwa.I-geotextile kufanele ilethwe endaweni yokugcina impahla, futhi ngeke ivezwe elangeni emoyeni ovulekile.I-geotextile egcinwe isikhathi esingaphezu kwezinyanga eziyisi-6 akufanele isetshenziswe.I-geotextile akumele ibe nejoyinti elivundlanayo, futhi ubude obugqagqene be-longitudinal akumele bube ngaphansi kuka-1m. Ukubeka kuzokuba sicaba futhi kukhululeke kahle.Ngemuva kokubeka i-geotextile kungqimba lwamatshe, hlola ukuthi i-lap joint iminyene yini.Lapho uthela futhi ucindezela umcamelo wokhonkolo ongenalutho, vimbela udaka ekungeneni kungqimba lwamatshe.Ngesikhathi sokuthululwa nokugxilwa kwe-slab ye-berth, hlola isigaba sepayipi lokudonsa ngezigaba.Dweba futhi ususe ama-sundries nganoma yisiphi isikhathi.I-filament geotextile ibilokhu iyimpahla yethu esiyikhethayo kumaphrojekthi angangeni manzi nangama-sepage, ngoba iyi-geosynthetics ekwazi ukungena kalula eyenziwe ngemicu yokwenziwa ngokubhoboza inaliti noma ukwelukwa.
Umkhiqizo oqediwe usesimweni sendwangu, ububanzi obujwayelekile obungamamitha angu-2-6.2 kanye nesisindo esingu-180-670 g/㎡.Ngesikhathi esifanayo, inokuhlunga okuhle kakhulu, ukuhlukaniswa, ukuqiniswa nokuvikelwa, amandla aphezulu aqinile, ukungena kahle, ukumelana nokushisa okuphezulu, ukumelana neqhwa, ukumelana nokuguga, ukumelana nokugqwala nezinye izici zokusebenza ezinhle.Ngaphezu kwalokho, i-filament geotextile ngokwayo inezikhala ezinhle zendwangu kanye nokunamathela okuhle, Njengoba i-fiber ithambile, inokumelana okuthile nokukhala, amandla olwelwesi olulwa nolwelwesi lwama-seepage kanye nokuguquguquka okuhle kokuguquguquka, kanye nomthamo omuhle wokudonsa indiza.I-soft surface enezikhala eziningi ine-coefficient ye-friction enhle, engandisa ukunamathela kwezinhlayiya zenhlabathi, ivimbele ukulahlekelwa kwezinhlayiya ezinhle futhi isuse amanzi amaningi ngesikhathi esifanayo.Indawo ethambile inekhono elihle lokuvikela.Ngakho-ke, i-filament geotextile isetshenziswe kakhulu kwezobunjiniyela bezitimela, futhi izuze izinzuzo zokunciphisa izindleko kanye nekhwalithi engcono.Eminyakeni yamuva nje, i-filament geotextile ingenye yemikhiqizo ephezulu ekhiqizwa ngezinto ezingavuthiwe ze-polyester.Isetshenziswa futhi yakhiwe ngokuvumelana nezidingo zobunjiniyela bezitimela, futhi umphumela uqashelwa ngokusekelwe ekuhlangenwe nakho kokusetshenziswa kwesikhathi eside.Selokhu kwathuthukiswa ubunjiniyela bezitimela nge-filament geotextile, imboni yezitimela yaseChina ibithuthuka ngesivinini esikhulu.Ujantshi wesitimela ohamba ngesivinini esiphezulu usebenzisa enye yezinto ezibalulekile kuma-geotextiles angangeni namanzi.
