Iqonga lokwahlulahlula inkunkuma yasekhaya, indawo yokulahla inkunkuma, indawo yokulahla inkunkuma, indawo yokulahla inkunkuma ngokweemfuno ezifanelekileyo, i-HDPE Geomembrane, indawo yokulahla inkunkuma ngokweemfuno ezifanelekileyo, i-HDPE Overlay film. Ngenxa yemeko-bume entsonkothileyo yokugubungela, indawo yokugubungela ifikelela kumawaka eemitha zesikwere, kwaye iindawo ezidityanisiweyo zeefilimu zokugubungela zinde, akunakuphepheka ukuba ezinye iifilimu zokugubungela zibe nokuvuza. Abasebenzi be-Landfill basebenzisa ixesha labo lasimahla ukulungisa ukuvuza kweefilimu zokugubungela. "Ifilimu yabekwa iiyure ezi-2 ezinesiqingatha kusasa, kwaye kwabekwa amaphepha ama-5." Ifilimu yokugubungela "ibhekisa kwi-geomembrane ye-polyethylene enobunzima obukhulu egqunywe kwinkunkuma." Emva kokuba inkunkuma igcwaliswe, ukuyigubungela ngale filimu kufana nokubeka 'ingubo' kwinkunkuma, enokunciphisa ivumba."
Inkqubo yokubeka ifilimu yokugquma inkunkuma
Indawo yokulahla inkunkuma engaphantsi kweyunithi, indlela yokulahla inkunkuma kunye nokuqina kwayo aziphumli. Indawo yokugcina inkunkuma ixhotyiswe ngeendawo ezimbini zomhlaba ezibekwe ngokweendawo ukuze yahlule yonke indawo yokugcina inkunkuma ibe ziindawo ezintathu zokulahla inkunkuma. Isicwangciso sokulahla inkunkuma seyunithi encinci sonyaka wonke siyaqulunqwa kwaye iyunithi yokusebenza ilawulwa ngokweemfuno zenkcazo, imibhobho yokukhupha amanzi amdaka kwiindawo zokulahla inkunkuma iyanqunyulwa kwaye ivalwe, ukuphambuka kwamanzi emvula kunye nelindle kwenziwa kangangoko, ubungakanani benkunkuma evelisiweyo buyancipha, kwaye iingozi zokusingqongileyo kunye neendleko zemveliso ziyancitshiswa ngokufanelekileyo.
Indawo yokulahla inkunkuma isebenzisa oomatshini abakhethekileyo, ii-bulldozer kunye nee-compactors zokugawula kunye nokudibanisa. Uxinano lwenkunkuma luvavanywa rhoqo, ukwakheka kwenkunkuma kuhlalutywa rhoqo, kwaye ukugoqa kunye nokudibanisa kwenziwa ngokwee-layered paving njengoko kufuneka. Ubukhulu bokugawula bulawulwa kwi-0.5 ukuya kwi-1 yemitha, kwaye ubukhulu beyunithi bulawulwa kwiimitha ezi-4 ukuya kwezi-6.
3. Yigqume yonke imihla ukuze uthintele ukusasazeka kwevumba, kwaye kwangaxeshanye unciphise amanzi emvula ukuba angangeni kwindawo yokulahla inkunkuma, ulawule ukuvela kweengcongconi neempukane, kwaye uthintele ukusasazeka kwevumba.
Indawo egqunywe kwindawo yokucocwa kwenkunkuma iya kusetyenziswa rhoqo emva kwemini. 1.0 HDPE. I-membrane igqunywe okwethutyana, kwaye zonke iindawo ezingaphandle kobuso bokusebenza ziyi-1.0 mm. Igqunywe ngefilimu ye-polyethylene enoxinano oluphezulu, kwaye ifilimu yokugquma kwindawo engakhange isetyenziswe kangangeentsuku ezingaphezu kwe-15 iyadityaniswa kwaye idityaniswe. Amanzi acacileyo kwifilimu akhutshwa ngethambeka lendalo okanye umsele wokukhupha amanzi emvula obekwe kwindawo, ukuze kuncitshiswe amanzi emvula ukuba angangeni kwindawo yokulahla inkunkuma, kwaye kulawulwe ngokufanelekileyo ukuzala kweengcongconi neempukane kunye nokusasazeka kwevumba. Olu nxibelelwano lubaluleke kakhulu, ngakumbi ekuphambukeni kwamanzi emvula kunye nelindle. Ebusika, siza kugqiba ukugrumba nokugcina imisele yokuthintela izikhukula, ukuqinisa iindlela okwethutyana kwiindawo zokulahla inkunkuma, ukuhlolwa nokulungiswa kweefilimu zokugquma, ukwakhiwa kwee-embankments zomhlaba ezibekwe kwiindawo ezithile, kunye nokufuduswa kunye nokwakhiwa kweepompo kwangaphambili. Yenza amalungiselelo apheleleyo okuqinisa ukhuseleko lwemveliso kunye nokunciphisa iingozi zokusingqongileyo ngexesha lemvula.
Inxalenye yoqhagamshelwano phakathi kwendawo yokulahla inkunkuma kunye nomthambeka kwindawo yedama ibekwe kumaleko okukhusela ingxowa yesanti angama-50 CM, umthambeka ulawulwa ngaphantsi kwe-1: 3, kwaye ulawulo lokuphakama kwenqwaba lwahlulwe lube yimo ye-longitudinal slope kunye ne-transverse slope. Indawo ezalisweyo isetyenziswa njenge-HDPE Membrane.
4. Akukho nto ishiyekileyo ekubulaweni kweentsholongwane kwindawo. Izitshizi zisetyenziselwa ukongeza iikhemikhali ngokuthe ngqo ezindleleni kwindawo leyo, kwaye iinkanunu zomoya zisetyenziselwa ukwenza imisebenzi yokutshiza ngokuzenzekelayo yokubulala iintsholongwane kunye nokususa ivumba elibi. Kwangaxeshanye, ukugqunywa kweeyunithi zokusebenza kuyaqiniswa. Okwangoku, impembelelo yokulawula iingcongconi, iimpukane kunye nevumba elibi kwindawo leyo ilungile.
Iinethi ezithintela ukubhabha zifakelwe kuzo zombini iziphelo zendawo yokulahla inkunkuma ukuze zivale ngokufanelekileyo izinto ezibhabhayo.
