Izindaba

Uma sikhuluma ngendima yefilimu yepulasitiki ekugxiliseni amanzi kanye ne-thermal, kufanele siqale sicabange ngefilimu yomhlaba engenamanzi.Lolu hlobo lwe-geomembrane ludume ngokusebenza kahle kakhulu futhi lungasetshenziswa kumaphrojekthi amaningi wamadamu omhlaba noma imisele.Mhlawumbe sizobona izindwangu ezingalukiwe ezimweni eziningi.I-Geomembrane ngokuyisisekelo iyi-chemical fiber emfishane.
I-Geomembrane inganwetshwa ngezinga elithile futhi ingasetshenziswa ezindaweni eziningi.Ngemuva kokuthi i-geomembrane ihlanganiswe nefilimu yepulasitiki, sithi ikhwalithi yefilimu yasekuqaleni yepulasitiki ingathuthukiswa ngokuphumelelayo, futhi ingahlangabezana nezidingo zethu eziningi.Lokhu kwaziswa kuvame ukubizwa ngokuthi i-geomembrane.Uma izinto zengezwa, amandla okungqubuzana kwendawo yokuxhumana angandiswa, futhi isendlalelo sokuzivikela singakha isimo esizinzile.
I-Geomembrane ngokuyinhloko iyi-chemical fiber emfushane
Ngaphezu kwalokho, i-geomembrane ingamelana nendlela ethile yangaphandle yokusabela kwamakhemikhali futhi inokumelana nokugqwala okuhle.Ngisho nasendaweni ene-asidi eqinile, izinhlobo ezithile ze-geomembrane zingagcinwa isikhathi eside.Ngokuvamile, izinto ze-geomembrane zesaba kakhulu izindawo ezine-asidi, ezine-alkali noma zikasawoti.Uma ufuna ukusebenzisa i-mulch, kungcono ukuyibeka endaweni ngaphandle kwelanga eliqondile.
Ngenxa yokuthi ingandisa impilo yesevisi ye-geomembrane futhi igweme izinto ezigciniwe zokukhanya, kungale ndlela kuphela i-geomembrane ingagwema ukusabela kwamakhemikhali.Ukukhanya kwelanga isikhathi eside kungase kwenyuse izinga lokushisa elingaphezulu le-geomembrane, ngakho-ke kuzobangela ukuqhekeka kwesakhiwo se-geomembrane.Kungase kungabonakali ukuthi kunomehluko omkhulu, kodwa empeleni, isimo se-geomembrane sishintshile.
Ngokuthuthuka komnotho, ukusetshenziswa kwe-geomembrane kanye ne-geotextile kuya ngokuya kunwebeka, kusetshenziswe ikakhulukazi ekulungiseni indawo, indawo yokuhlanza indle, ukuvimbela ukugeleza kwamadamu, iphrojekthi yesitimela esihamba ngaphansi komhlaba namanye amaphrojekthi.Uyini umehluko phakathi kwe-geomembrane ne-geotextile lapho usebenzisa i-geotextile?Ake sibheke.
Okungukuthi, izici ezahlukene:
1. Izici ze-geomembrane:
I-Geomembrane iwuhlobo lwezinto ezilwa nokubona ikhasi ezakhiwe ngefilimu yepulasitiki nendwangu engalukiwe.Ukusebenza kwe-anti-seepage kwe-geomembrane yezinto ezintsha kuncike kakhulu ekusebenzeni okuphikisayo kwefilimu yepulasitiki.
I-1) Inokumelana okuhle kakhulu nokuqhekeka kokucindezeleka kwemvelo kanye nokugqwala kwamakhemikhali.
2) Ibanga lokushisa elikhulu kanye nempilo ende yesevisi.
I-3) I-anti-seepage kanye nesistimu yokukhipha amanzi isethelwe ukusebenza emzimbeni womshini futhi inemisebenzi yokuhlukanisa nokuqinisa.
I-4) Amandla aphezulu ahlanganisiwe, amandla aphezulu we-peel kanye nokumelana nokubhoboza okuhle.
5) Amandla okudonsa amanzi aqinile, i-coefficient enkulu yokungqubuzana kanye ne-coefficient encane yokunwetshwa komugqa.
2. Izici ze-geotextile
Ama-geotextiles, aziwa nangokuthi ama-geotextiles, angama-geosynthetics atholakalayo enziwe ngemicu eyenziwe umuntu, izinaliti noma ama-braids.I-Geotextile wuhlobo olusha lwe-geosynthetics.Umkhiqizo oqediwe uyindwangu, ngokuvamile amamitha angu-4-6 ububanzi namamitha angu-50-100 ubude.Ama-geotextiles ahlukaniswe abe ama-geotextiles nama-geotextile angalukiwe.
I-1) Njengamanje, imicu yokwenziwa esetshenziswa ekukhiqizeni i-geotextile ikakhulukazi ihlanganisa i-polyamide fiber, i-polyester fiber, i-polypropylene fiber, i-polypropylene fiber, njll., konke okunamandla okungcwaba kanye nokubola.
2) I-Geotextile iwuhlobo lwempahla evuthekayo enokuhlunga okuhle nemisebenzi yokuzihlukanisa.
3) I-Nonwoven geotextile inokusebenza okuhle kokukhipha amanzi ngenxa yesakhiwo sayo esithambile.
4) I-Geotextile inokumelana nokubhoboza okuhle, ngakho inokusebenza okuhle kokuvikela.
5) I-Geotextile ine-coefficient enhle yokungqubuzana namandla aqinile, futhi inokusebenza kokuqiniswa kwe-geotextile.
2 Ukungena kwamanzi okuhlukile:
I-Geomembrane ayingeneki, kuyilapho i-geotextile ikwazi ukungena.
3 Izinto ezahlukahlukene:
Ama-geomembranes amapuleti anobukhulu obuhlukahlukene enziwe nge-resin yamangqamuzana aphezulu noma irabha ngokufudumeza i-extrusion noma ukubunjwa kokushaywa.Ziwulwelwesi olungenakunyakaziswa olwenziwe nge-polyethylene ephezulu nephansi, i-EVA, njll. Ama-Geotextiles ayi-polyester, i-acrylic, njll. Izindwangu ezingalukiwe ezicutshungulwa ngokuphotha, izingubo zekhadi noma izindwangu ezilukiwe ngomshini, izindwangu ezingalukiwe noma ukuphotha, i-polyester, i-polypropylene, i-acrylic. ifayibha, inayiloni, njll.
4. Umehluko wokusebenza:
Ama-Geotextiles anokuhlunga okuhle, ama-drainage, ukuhlukaniswa, ukuqinisa, ukuvimbela ukuphuma kwamanzi kanye nemisebenzi yokuvikela, futhi anesisindo esilula, anamandla aqinile, akwazi ukungena emoyeni, izinga lokushisa eliphezulu nokumelana nokuguga.
I-Geomembrane iyi-polymer chemical flexible material enamandla amancane adonsela phansi, i-ductility eqinile, ukuguquguquka okuqinile, ukumelana nokugqwala, ukumelana nokushisa okuphansi kanye nokumelana nesithwathwa okuhle.
Izinjongo ezehlukene:
I-Geotextiles isetshenziselwa ikakhulukazi ukuqinisa, ukuhlukanisa, ukukhipha amanzi, ukuhlunga nokuvikela.
I-Geomembrane isetshenziselwa kakhulu ukuvala, ukwahlukanisa, ukuvimbela ukuphuma kwamanzi kanye nokuvimbela ukuqhekeka.
