Idamu ledamu i-geomembrane
Incazelo emfushane:
- Ama-geomembranes asetshenziselwa amadamu echibi enziwe ngezinto ze-polymer, ikakhulukazi i-polyethylene (PE), i-polyvinyl chloride (PVC), njll. Lezi zinto zikwazi ukungena emanzini aphansi kakhulu futhi zingavimbela ngempumelelo amanzi ukuthi angangeni. Isibonelo, i-polyethylene geomembrane ikhiqizwa ngokusabela kwe-polymerization ye-ethylene, futhi ukwakheka kwayo kwamangqamuzana kuhlangene kangangokuthi ama-molecule amanzi awakwazi ukudlula kuwo.

1.Izimpawu Zokusebenza
- Ukusebenza kwe-Anti-seepage:
Lokhu ukusebenza okubaluleke kakhulu kwama-geomembranes ekusetshenzisweni kwamadamu echibi. I-geomembranes yekhwalithi ephezulu ingaba ne-coefficient yokungena efinyelela ku-10⁻¹² - 10⁻¹³ cm/s, cishe ivimbe ngokuphelele ukudlula kwamanzi. Uma kuqhathaniswa nesendlalelo sobumba esivamile esiphikisana ne-seepage, umphumela walo wokulwa nokubona uphawuleka kakhulu. Isibonelo, ngaphansi kokucindezela okufanayo kwekhanda lamanzi, inani lamanzi ageleza ku-geomembrane liyingxenyana nje yalokho ngongqimba lobumba oluphikisana nokuvuleka. - Ukusebenza kwe-Anti-puncture:
Ngesikhathi kusetshenziswa ama-geomembranes emadamini esiziba, angase abhodlozwe izinto ezicijile njengamatshe namagatsha ngaphakathi emzimbeni wedamu. Ama-geomembranes amahle anamandla aphezulu okulwa nokubhoboza. Isibonelo, amanye ama-geomembranes ayinhlanganisela anezendlalelo zangaphakathi zokuqinisa ifayibha ezingamelana ngempumelelo nokubhobozwa. Ngokuvamile, amandla e-anti-puncture ama-geomembranes afanelekayo angafinyelela ku-300 - 600N, ukuqinisekisa ukuthi angeke alimale kalula endaweni eyinkimbinkimbi yomzimba wedamu. - Ukumelana Nokuguga:
Njengoba amadamu echibi esebenza isikhathi eside, ama-geomembranes adinga ukumelana nokuguga okuhle. Ama-anti-aging agents ayengezwa phakathi nenqubo yokukhiqiza ama-geomembranes, okubenza bakwazi ukugcina ukusebenza okuzinzile isikhathi eside ngaphansi kwethonya lezici zemvelo ezifana nemisebe ye-ultraviolet kanye noshintsho lokushisa. Isibonelo, ama-geomembranes acutshungulwe ngokwakhiwa okukhethekile namasu angaba nempilo yesevisi yeminyaka engama-30 - 50 ngaphandle. - Ukuguquguquka Ukuguquguquka:
Idamu lizokonakala okuthile njengokuhlaliswa kanye nokugudluzwa ngesikhathi sokugcina amanzi. Ama-geomembranes angakwazi ukuzivumelanisa nokukhubazeka okunjalo ngaphandle kokuqhekeka. Isibonelo, zingakwazi ukwelula nokugoba ngezinga elithile kanye nokuhlaliswa komzimba wedamu. Amandla abo aqinile angafinyelela ku-10 - 30MPa, okubenza bakwazi ukumelana nokucindezeleka okubangelwa ukuguqulwa komzimba wedamu.
kness ngokwezidingo zephrojekthi. Ugqinsi lwe-geomembrane luvamise ukuba ngu-0.3mm kuya ku-2.0mm.
- Ukungangenisi amanzi: Qinisekisa ukuthi i-geomembrane inokungangeni kahle ukuvimbela amanzi enhlabathini ukuthi angangeni kuphrojekthi.
2.Amaphuzu Abalulekile Wokwakha
- Ukwelashwa Okuyisisekelo:
Ngaphambi kokubeka ama-geomembranes, isisekelo sedamu kufanele sibe sicaba futhi siqine. Izinto ezicijile, ukhula, inhlabathi exegayo namadwala ebusweni besisekelo kufanele kususwe. Isibonelo, iphutha lokucaba kwesisekelo ngokuvamile liyadingeka ukuthi lilawulwe phakathi kuka-±2cm. Lokhu kungavimbela i-geomembrane ukuthi ingaklwejwa futhi kuqinisekise ukuthintana okuhle phakathi kwe-geomembrane nesisekelo ukuze ukusebenza kwayo okunqanda ukuvuleka kwekhasi kukhishwe. - Indlela yokubeka:
I-geomembranes ivamise ukuhlukaniswa ngokushisela noma nge-bonding. Lapho u-welding, kuyadingeka ukuqinisekisa ukuthi izinga lokushisa lokushisela, isivinini nokucindezela kufanelekile. Isibonelo, kuma-geomembranes ashiselwe ukushisa, izinga lokushisa lokushisela ngokuvamile liphakathi kuka-200 - 300 °C, isivinini sokushisela sicishe sibe ngu-0.2 - 0.5m/min, futhi ingcindezi yokushisela iphakathi kuka-0.1 - 0.3MPa ukuqinisekisa ikhwalithi yokushisela nokuvimbela. izinkinga zokuvuza ezibangelwa ukushisela okungalungile. - Uxhumano Lwe-peripheral:
Ukuxhunywa kwama-geomembranes nesisekelo sedamu, izintaba ezinhlangothini zombili zedamu, njll. emaphethelweni edamu kubaluleke kakhulu. Ngokuvamile, imisele okuhanjwa kuyo, i-concrete caping, njll. izokwamukelwa. Isibonelo, umsele okuhange kuwo onokujula okungama-30 - 50cm ubekwe esisekelweni sedamu. Unqenqema lwe-geomembrane lubekwe emseleni wokunamathisela futhi luhlanganiswe nezinto zomhlabathi ezihlangene noma ukhonkolo ukuze kuqinisekiswe ukuthi i-geomembrane ixhunywe ngokuqinile nezakhiwo ezizungezile futhi ivimbele ukuvuza kwe-peripheral.
3.Isondlo kanye Nokuhlola
- Ukunakekela Umjikelezo:
Kuyadingeka ukuhlola njalo ukuthi kukhona yini umonakalo, izinyembezi, ama-punctures, njll ebusweni be-geomembrane. Isibonelo, ngesikhathi sokusebenza kwedamu, izisebenzi zokunakekela idamu zingenza ukuhlola kanye ngenyanga, zigxile ekuhloleni i-geomembrane ezindaweni lapho izinga lamanzi lishintsha njalo kanye nezindawo ezinokukhubazeka okukhulu kwedamu. - Izindlela Zokuhlola:
Amasu okuhlola angalimazi angamukelwa, njengendlela yokuhlola inhlansi. Ngale ndlela, i-voltage ethile isetshenziswa ebusweni be-geomembrane. Uma kunomonakalo ku-geomembrane, kuzokwenziwa izinhlansi, ukuze amaphuzu alimele atholakale ngokushesha. Ngaphezu kwalokho, kukhona futhi indlela yokuhlola i-vacuum. Isikhala esivaliwe siyakhiwa phakathi kwe-geomembrane nedivayisi yokuhlola, futhi ukuba khona kokuvuza ku-geomembrane kwahlulelwa ngokubheka ushintsho lwedigri ye-vacuum.
