High-density polyethylene (HDPE) geomembranes for landfills

Incazelo emfushane:

I-HDPE geomembrane liner ibunjwe nge-polyethylene polymer material. Umsebenzi wayo oyinhloko ukuvimbela ukuvuza koketshezi kanye nokuhwamuka kwegesi. Ngokwezinto zokusetshenziswa zokukhiqiza, ingahlukaniswa i-HDPE geomembrane liner kanye ne-EVA geomembrane liner.

Incazelo Yemikhiqizo

I-HDPE geomembrane ingenye yezinto ze-geosynthetic, inokumelana okuhle kakhulu nokucindezeleka kwemvelo, ukumelana nezinga lokushisa eliphansi, ukumelana nokuguga, ukumelana nokugqwala, kanye nebanga lokushisa elikhulu kanye nempilo ende yesevisi, esetshenziswa kabanzi ekungangenisi kokulahlwa kukadoti wasekhaya, imfucuza eqinile. ukungakwazi ukucwiliswa kokulahlwa kwemfucuza, ukungangeneli kwesikhungo sokuhlanza indle, ukungakwazi ukucwilisa kwechibi lokwenziwa, ukuhlanzwa kwemisila kanye namanye amaphrojekthi angawohloki.

Izimpawu Zokusebenza

1. Ayiqukethe izithasiselo zamakhemikhali, ayitholi ukwelashwa kokushisa, iyimpahla yokwakha ehambisana nemvelo.
2. Inezici ezinhle zemishini, amanzi angena kalula, futhi ingamelana nokugqwala, inqande ukuguga.
3. Ngokumelana okungcwatshwe okuqinile, ukumelana nokugqwala, isakhiwo esithambile, nokusebenza kahle kokukhipha amanzi.
4. Ine-coefficient enhle yokungqubuzana namandla aqinile, ngokusebenza kokuqinisa i-geotechnical.
5. Ngokuzihlukanisa, ukuhlunga, ukugeleza kwamanzi, ukuvikelwa, ukuzinza, ukuqinisa kanye neminye imisebenzi.
6. Ingakwazi ukuzivumelanisa nesisekelo esingalingani, ingamelana nomonakalo wokwakhiwa kwangaphandle, i-creep iba yincane.
7. Ukuqhubeka okuphelele kuhle, isisindo esincane, ukwakhiwa okulula.
8. Kuyinto ekwazi ukungena, ngakho inomsebenzi omuhle wokuhlukanisa ukuhlunga, ukumelana nokubhoboza okuqinile, ngakho inokusebenza okuhle kokuvikela.

Ukusetshenziswa kwe-geombrane

1. Indawo yokulahla imfucumfucu, indle noma lawula ukugeleza kwezinsalela zemfucuza ogwini lolwandle.
2. Idamu lechibi, amadamu ezinsika, idamu lokukhucululwa kwendle nedamu, umzila, ukugcinwa kwamachibi awuketshezi (umgodi, insimbi).
3. Umzila ongaphansi komhlaba, umhubhe, ulwelwesi olunqanda ukuvuleka kwesitezi esingaphansi nomhubhe.
4. Amanzi olwandle, amapulazi ezinhlanzi emanzini angenasawoti.
5. Umgwaqo omkhulu, izisekelo zomgwaqo omkhulu nojantshi wesitimela; inhlabathi enwetshiwe kanye nokulahlekelwa okugoqekayo kongqimba olungangeni manzi.
6. I-anti-seepage yokuphahla.
7. Ukulawula umbhede womgwaqo kanye nokunye ukugeleza kwe-saline yesisekelo.
8. I-Dike, ingaphambili le-sam foundation yokuvimbela ukugeleza kwamanzi, izinga lesendlalelo esime mpo esingenakunyakaziswa, i-cofferdam yokwakha, indawo kadoti.
