Izindaba

I-Geosynthetics iwuhlobo olusha lwezinto zobunjiniyela be-geotechnical, ezingenziwa ngama-polymers emvelo noma enziwe umuntu (ipulasitiki, i-chemical fiber, irabha yokwenziwa, njll.) futhi ibekwe ngaphakathi, ngaphezulu noma phakathi kwezingqimba zenhlabathi ezihlukene ukuze kuqiniswe noma kuvikelwe inhlabathi. inhlabathi.
Njengamanje, i-Geotextiles isetshenziswe kabanzi emigwaqweni, emigwaqweni, emigwaqweni, ekongiweni kwamanzi, amandla kagesi, ukwakhiwa, amachweba, izimayini, imboni yezempi, ukuvikelwa kwemvelo kanye neminye imikhakha. Izinhlobo eziyinhloko ze-geosynthetics zihlanganisa ama-geotextiles, ama-geogrids, ama-geogrids, ama-geomembranes, ama-geogrids, ama-geo composites, ama-bentonite mats, ama-geological slopes, igwebu le-geo, njll. Kuzicelo zobunjiniyela, i-Geotextiles ingasetshenziswa yodwa noma ihlanganiswe nama-geogrids, ama-geomembranes, ama-geogrids, ama-geogrids, ama-geogrids, ama-geogrids, njll. izinto ezihlanganisiwe ze-geo.

Njengamanje, izinto zokusetshenziswa ze-geotextiles ikakhulukazi imicu yokwenziwa, esetshenziswa kakhulu imicu ye-polyester nemicu ye-polypropylene, ilandelwa imicu ye-polyamide nemicu ye-polyvinyl acetal.
I-polyester fiber inezici ezinhle zomzimba nemishini, ukuqina okuhle kakhulu kanye nezakhiwo ezinwabuzelayo, indawo ephezulu yokuncibilika, ukumelana nokushisa okuphezulu, ukumelana nokuguga, ubuchwepheshe bokukhiqiza obuvuthiwe kanye nesabelo esikhulu semakethe. Okubi ukungenzi kahle kwe-hydrophobicity, kulula ukunqwabelana i-condensate yezinto zokufakelwa ezishisayo, ukusebenza okungekuhle kwezinga lokushisa eliphansi, i-vitrify kalula, amandla ancishisiwe, i-asidi ephansi kanye nokumelana ne-alkali.
I-polypropylene fiber inokunwebeka okuhle, futhi ukunwebeka kwayo okusheshayo nokuqina kwayo kungcono kune-polyester fiber. I-asidi enhle ne-alkali ukumelana, ukumelana nokugqoka, ukumelana nesikhutha kanye nokumelana nokushisa okuphansi; Ine-hydrophobicity enhle nokumuncwa kwamanzi, futhi ingadlulisela amanzi endaweni engaphandle eduze kwe-axis yefiber. Ukuminyana kuncane, kuphela ama-66% we-polyester fiber. Ngemuva kwezikhathi eziningi zokubhala, i-fine denier fiber enesakhiwo esihlangene nokusebenza okuphakeme ingatholakala, bese emva kwenqubo yokuqinisa, amandla ayo angaba ngaphezulu. Ububi ukumelana nokushisa okuphezulu, indawo yokuthambisa engu-130 ~ 160 ℃, ukumelana nokukhanya okubi, ukubola kalula elangeni, kodwa izithasiselo ze-UV nezinye izithasiselo zingangezwa ukuze zikwazi ukumelana ne-UV.
Ngokungeziwe kule micu engenhla, imicu yejute, imicu ye-polyethylene, imicu ye-polylactic acid, njll. ingasetshenziswa futhi njengezinto zokusetshenziswa zama-geotextiles angalukiwe. Imicu yemvelo nemicu ekhethekile ingene kancane kancane emikhakheni ehlukahlukene yokusetshenziswa kwe-geotextiles. Isibonelo, imicu yemvelo (i-jute, igobolondo likakhukhunathi i-fiber, i-bamboo pulp fiber, njll.) isetshenziswe ekunciphiseni, emanzini, ekuvikelweni kwebhange, ekuvimbeleni ukuguguleka kwenhlabathi kanye neminye imikhakha.
Uhlobo lwe-Geotextile
I-Geotextile iwuhlobo lwe-geotextile evunyelekayo eyenziwe ngemicu ye-polymer ngokucindezela okushisayo, ukusimende nokweluka, okwaziwa nangokuthi i-geotextile, okuhlanganisa ukwelukwa nokungalukwa.
Imikhiqizo yokunitha ye-Geotextile ihlanganisa ukunitha (i-plain weave, i-round weave), ukunitha (i-plain weave, i-twill), ukunitha (ukunitha kwe-warp, ukunitha kwezinaliti) nezinye izinqubo zokukhiqiza.
I-Nonwoven geotextiles ihlanganisa izinqubo zokukhiqiza ezifana nendlela yokuqinisa imishini (indlela ye-acupuncture, indlela yokubhoboza amanzi), indlela yokubopha amakhemikhali (indlela yokufafaza ngeglue, indlela yokufaka i-impregnation), indlela yokuncibilika okushisayo (indlela yokugoqa eshisayo, indlela yomoya oshisayo), njll.
I-geotextile elukiweyo ingeye-geotextile eyethulwe okokuqala, kodwa inemikhawulo yezindleko eziphezulu nokusebenza kabi. Ngasekupheleni kweminyaka yawo-1960, kwasungulwa ama-geotextiles angalukiwe. Ekuqaleni kwawo-1980, i-China yaqala ukusebenzisa lezi zinto ezinhlanganweni zobunjiniyela. Ngokuduma kwama-nonwovens abhontshiwe ngenaliti kanye nama-nonwovens aphothiwe, inkambu yokusetshenziswa kwama-nonwovens ibanzi kakhulu kunaleyo yama-geotextiles akhubazekile, futhi ithuthuke ngokushesha. I-China isithuthuke yaba umkhiqizi omkhulu we-Nonwovens emhlabeni, futhi kancane kancane iqhubekela phambili kumkhiqizi onamandla.
Ukuhlunga kwe-Geotextile, ukuchelela, ukuhlukaniswa, ukuqiniswa, ukuvimbela ukubola, ukuvimbela ukutheleleka, isisindo esilula, amandla aqinile, ukungena okuhle nokumelana nokushisa okuphansi, ukumelana nokubanda, ukumelana nokuguga, ukumelana nokugqwala, ukuguquguquka nokunye, kusetshenziswe kabanzi emikhakheni ehlukahlukene. Impilo yedolobha elihle kakhulu lomsebenzi ikhombisa ngokuphelele okwesikhashana ukuthi asikho esinye isifo.
Kungani kufanele kwenziwe ukubalwa kwezimali okuqondile ngaphambi kokwakhiwa kwe-geotextile? Ochwepheshe abaningi be-novice abacaci kahle nge-accounting ethile ye-geotextiles ngaphambi kokwakhiwa. Kuya ngenkontileka yokuhlela kanye nendlela yokucaphuna yokwakha. Ngokuvamile, ibalwa ngokwendawo. Udinga ukunaka ukuthambekela. Udinga ukuyiphindaphinda nge-slope coefficient.
