Ibhodi yokugcina amanzi kunye neyokukhupha amanzi yophahla lwegaraji engaphantsi komhlaba
Inkcazo emfutshane:
Ibhodi yokugcina amanzi kunye neyokukhupha amanzi yenziwe nge-polyethylene enoxinano oluphezulu (HDPE) okanye i-polypropylene (PP), eyenziwe ngokufudumeza, ukucinezela kunye nokubumba. Yibhodi ekhaphukhaphu enokwenza umjelo wokukhupha amanzi onobunzima obuthile obuxhasa indawo kwaye inokugcina amanzi.
Inkcazelo yeemveliso
Ibhodi yokugcina amanzi kunye neyokukhupha amanzi inemisebenzi emibini ebanzi: ukugcina amanzi kunye nokukhupha amanzi. Ibhodi inophawu lokuqina okuphezulu kakhulu kwendawo, kwaye amandla ayo okucindezela angcono kakhulu kuneemveliso ezifanayo. Iyakwazi ukumelana nemithwalo ephezulu yoxinzelelo engaphezulu kwe-400Kpa, kwaye ingakwazi ukumelana nemithwalo enzima ebangelwa kukuxinana koomatshini ngexesha lenkqubo yokuzalisa uphahla emva kokutyala.
Iimpawu zeMveliso
1. Kulula ukuyakha, kulula ukuyigcina, kwaye ingabizi kakhulu.
2. Ukumelana nomthwalo okuqinileyo kunye nokuqina.
3. Inokuqinisekisa ukuba amanzi agqithisileyo akhutshwa ngokukhawuleza.
4. Indawo yokugcina amanzi inokugcina amanzi athile.
5. Ingabonelela ngamanzi neoksijini eyaneleyo yokukhula kwezityalo.
6. Umsebenzi wokukhusela uphahla olukhaphukhaphu noluqinileyo.
Isicelo
Isetyenziselwa ukwenza uhlaza eluphahleni, ukwenza uhlaza phantsi komhlaba kwiiphaneli zophahla, izikwere zasezidolophini, amabala egalufa, amabala emidlalo, izityalo zokucoca amdaka, ukwenza uhlaza kwizakhiwo zikawonke-wonke, ukwenza uhlaza olusikwere, kunye neeprojekthi zokwenza uhlaza ezindleleni ngaphakathi epakini.
Amanyathelo okukhusela ulwakhiwo
1. Xa zisetyenziswa kumachibi eentyatyambo, kwiindawo zokubeka iintyatyambo nakwiindawo zokubeka iintyatyambo egadini, izinto eziqhelekileyo zitshintshwa ngokuthe ngqo ziipleyiti zokugcina amanzi kunye nee-geotextiles zesihluzi (ezifana neeleya zesihluzi ezenziwe ngodongwe, iingqalutye okanye amaqokobhe).
2. Ukuze kuhlaziywe uludwe oluqinileyo olufana nophahla olutsha noludala okanye uphahla lobunjineli obungaphantsi komhlaba, ngaphambi kokubeka ibhodi yokugcina amanzi kunye nokukhupha amanzi, coca inkunkuma kwindawo leyo, seta umaleko ongangeni manzi ngokweemfuno zemizobo yoyilo, uze usebenzise udaka lwesamente ukuze uthambekele, ukuze umphezulu ungabi na-convex ecacileyo kunye ne-convex, ibhodi yokugcina amanzi kunye nokukhupha amanzi ikhutshwe ngendlela ecwangcisiweyo, kwaye akukho mfuneko yokubeka umsele wokukhupha amanzi ongaboniyo ngaphakathi kwendawo yokubeka.
3. Xa isetyenziselwa ukwenza ibhodi yesandwich yesakhiwo, ibhodi yokugcina amanzi kunye nokukhupha amanzi ibekwa kwibhodi yesamente yophahla, kwaye kwakhiwa udonga olunye ngaphandle kwebhodi yokugcina amanzi kunye nokukhupha amanzi, okanye ikhonkrithi isetyenziselwa ukuyikhusela, ukuze amanzi angaphantsi komhlaba angene emseleni ongaboniyo kunye nomngxuma wokuqokelela amanzi ngokusebenzisa indawo engaphezulu kwebhodi yokukhupha amanzi.
4. Ibhodi yokugcina kunye neyokukhupha amanzi idityaniswe, kwaye isithuba xa kubekwa sisetyenziswa njengomjelo osezantsi wokukhupha amanzi, kwaye umaleko wokucoca i-geotextile kunye nowokufuma kufuneka udityaniswe kakuhle xa kubekwa.
5. Emva kokuba ibhodi yokugcina kunye neyokukhupha amanzi ibekwe, inkqubo elandelayo inokwenziwa ukubeka i-filter geotextile kunye nomaleko we-matrix ngokukhawuleza ukuthintela umhlaba, isamente kunye nesanti etyheli ekuvaleni imbobo okanye ukungena kwindawo yokugcina amanzi, isinki kunye nomjelo wokukhupha amanzi webhodi yokugcina kunye nokukhupha amanzi. Ukuqinisekisa ukuba ibhodi yokugcina kunye nokukhupha amanzi idlala indima yayo ngokupheleleyo, ibhodi yokusebenza ingafakwa kwi-filter geotextile ukuze kube lula ukwakha uhlaza.
