I-geomembrane yedamu ledamu

Incazelo emfushane:

Ama-geomembrane asetshenziselwa amadamu okugcina amanzi enziwe ngezinto ze-polymer, ikakhulukazi i-polyethylene (PE), i-polyvinyl chloride (PVC), njll. Lezi zinto zinokungena kwamanzi okuphansi kakhulu futhi zingavimbela ngempumelelo amanzi ukuthi angangeni. Isibonelo, i-polyethylene geomembrane ikhiqizwa ngokusabela kwe-polymerization kwe-ethylene, futhi isakhiwo sayo sama-molecule sincane kakhulu kangangokuthi ama-molecule amanzi awakwazi ukudlula kuwo.

1.Izici Zokusebenza

Ukusebenza Okungangeni Ukuvuza:
Lokhu ukusebenza okubaluleke kakhulu kwama-geomembrane ekusetshenzisweni kwamadamu okugcina amanzi. Ama-geomembrane asezingeni eliphezulu angaba ne-permeability coefficient efinyelela ku-10⁻¹² - 10⁻¹³ cm/s, cishe evimba ngokuphelele ukudlula kwamanzi. Uma kuqhathaniswa nesendlalelo sobumba esivamile esivimbela ukuvuza kwamanzi, umphumela waso wokungavuki kwamanzi umangalisa kakhulu. Isibonelo, ngaphansi kwengcindezi efanayo yekhanda lamanzi, inani lamanzi aphumayo kwi-geomembrane liyingxenyana nje yalelo lesendlalelo sobumba esivimbela ukuvuza kwamanzi.
Ukusebenza Okungabhobozi:
Ngesikhathi sokusetshenziswa kwama-geomembrane emadamini okugcina amanzi, angase abhobozwe izinto ezibukhali njengamatshe namagatsha ngaphakathi komzimba wedamu. Ama-geomembrane amahle anamandla aphezulu okulwa nokubhoboza. Isibonelo, amanye ama-geomembrane ahlanganisiwe anezendlalelo zokuqinisa i-fiber yangaphakathi ezingamelana ngempumelelo nokubhoboza. Ngokuvamile, amandla okulwa nokubhoboza ama-geomembrane afanelekayo angafinyelela ku-300 - 600N, okuqinisekisa ukuthi ngeke alimale kalula endaweni eyinkimbinkimbi yomzimba wedamu.
Ukumelana Nokuguga:
Njengoba amadamu okugcina amanzi ephila isikhathi eside, ama-geomembrane adinga ukumelana nokuguga okuhle. Ama-anti-aging agents ayengezwa ngesikhathi senqubo yokukhiqizwa kwama-geomembrane, okuwenza akwazi ukugcina ukusebenza okuzinzile isikhathi eside ngaphansi kwethonya lezici zemvelo ezifana nemisebe ye-ultraviolet kanye nokushintsha kwezinga lokushisa. Isibonelo, ama-geomembrane acutshungulwe ngezakhiwo ezikhethekile namasu angaba nokuphila kweminyaka engama-30 - 50 ngaphandle.
Ukuzivumelanisa Nezimo Kokuguquka:
Idamu lizobhekana nokuguquguquka okuthile njengokuhlala phansi kanye nokufuduka ngesikhathi senqubo yokugcina amanzi. Ama-geomembrane angazivumelanisa nokuguquguquka okunjalo ngaphandle kokuqhekeka. Isibonelo, anganwebeka futhi agobe ngezinga elithile kanye nokuhlala phansi komzimba wedamu. Amandla awo okubamba ngokuvamile angafinyelela ku-10 - 30MPa, okuwenza akwazi ukumelana nokucindezeleka okubangelwa ukuguquguquka komzimba wedamu.

ukujiya kwe-geomembrane ngokuvamile kusuka ku-0.3mm kuya ku-2.0mm.
- Ukungangenwa: Qinisekisa ukuthi i-geomembrane inokungangenwa kahle ukuvimbela amanzi enhlabathini ukuthi angangeni kuphrojekthi.

2. Amaphuzu Abalulekile Okwakha

Ukwelashwa Okuyisisekelo:
Ngaphambi kokubeka ama-geomembrane, isisekelo sedamu kumele sibe sicaba futhi siqine. Izinto ezibukhali, ukhula, inhlabathi ekhululekile kanye namatshe ebusweni besisekelo kufanele kususwe. Isibonelo, iphutha lokusicaba kwesisekelo ngokuvamile liyadingeka ukuze lilawulwe ngaphakathi kuka-±2cm. Lokhu kungavimbela i-geomembrane ukuthi ingaklwebhi futhi kuqinisekiswe ukuthintana okuhle phakathi kwe-geomembrane nesisekelo ukuze ukusebenza kwayo okungangeni amanzi kusebenze.
Indlela Yokubeka:
Ama-geomembrane avame ukuxhunywa ngokushisela noma ngokubopha. Lapho kushiselwa, kuyadingeka ukuqinisekisa ukuthi izinga lokushisa lokushisela, isivinini kanye nengcindezi kuyafaneleka. Isibonelo, kuma-geomembrane ashisiwe ngokushisa, izinga lokushisa lokushisela ngokuvamile liphakathi kuka-200 - 300 °C, ijubane lokushisela lingaba ngu-0.2 - 0.5m/min, kanti ingcindezi yokushisela iphakathi kuka-0.1 - 0.3MPa ukuqinisekisa ikhwalithi yokushisela nokuvimbela izinkinga zokuvuza ezibangelwa ukushisela okungekuhle.
Ukuxhumeka Kwe-Peripheral:
Ukuxhumana kwama-geomembrane nesisekelo sedamu, izintaba ezinhlangothini zombili zedamu, njll. emngceleni wedamu kubaluleke kakhulu. Ngokuvamile, kuzosetshenziswa imisele yokunamathisela, ukuvala ukhonkolo, njll.. Isibonelo, umsele wokunamathisela onobubanzi obungu-30 - 50cm ubekwa esisekelweni sedamu. Unqenqema lwe-geomembrane lufakwa emseleni wokunamathisela futhi luqiniswe ngezinto zomhlabathi ezihlanganisiwe noma ukhonkolo ukuqinisekisa ukuthi i-geomembrane ixhunywe ngokuqinile nezakhiwo ezizungezile futhi ivimbele ukuvuza okungaphandle.

3. Ukugcinwa Nokuhlolwa

Ukulungiswa Okuvamile:
Kuyadingeka ukuhlola njalo ukuthi kukhona yini umonakalo, ukudabuka, ukubhoboza, njll. ebusweni be-geomembrane. Isibonelo, ngesikhathi sokusebenza kwedamu, abasebenzi bokulungisa bangenza ukuhlolwa kanye ngenyanga, bagxile ekuhloleni i-geomembrane ezindaweni lapho izinga lamanzi lishintsha khona njalo kanye nezindawo ezinokuguquguquka okukhulu komzimba wedamu.
Izindlela Zokuhlola:
Amasu okuhlola angonakalisi angasetshenziswa, njengendlela yokuhlola inhlansi. Kule ndlela, kufakwa i-voltage ethile ebusweni be-geomembrane. Uma kukhona umonakalo kwi-geomembrane, kuzokhiqizwa izinhlansi, ukuze amaphuzu alimele atholakale ngokushesha. Ngaphezu kwalokho, kukhona nendlela yokuhlola i-vacuum. Isikhala esivaliwe sakhiwa phakathi kwe-geomembrane nedivayisi yokuhlola, futhi ukuba khona kokuvuza kwi-geomembrane kwahlulelwa ngokubona ushintsho lwezinga le-vacuum.
