Iqonga lendawo yokulahla inkunkuma yasekhaya eligubungela ummandla we-HDPE Geomembrane ，Zowuni isigqubuthelo senkunkuma ngokweenkcukacha ezifanelekileyo zokulahla ifilim yeHDPE eWalekeneyo. Ngenxa yommandla onzima wokugubungela, indawo yokugubungela ifikelela kumashumi amawaka eemitha zeskweri, kwaye iindibano zeefilimu ezigubungelayo zinde, akunakuphepheka ukuba ezinye iifilimu ezigubungelayo ziya kuba nokuvuza. Abasebenzi betiphu basebenzisa ixesha labo lokukhulula ukulungisa ukuvuza kweefilimu ezigqumayo. "Ifilimu yabekwa iiyure ezi-2 ezinesiqingatha kusasa, kwaye kwabekwa amaphepha ama-5." Ifilimu yokugquma "ibhekisa kwi-polyethylene geomembrane ephezulu egqunywe kwinkunkuma." Emva kokuba inkunkuma ihlanjwe, ukuyigubungela ngale filimu ilingana nokubeka i-a'coat'on inkunkuma, enokunciphisa iphunga. “
Inkqubo yokubeka ifilimu yokugubungela inkunkuma yokulahla inkunkuma
Indawo yokulahla inkunkuma ephantsi, ukugada inkunkuma kunye nokuxinzelelwa kwazo aziphumli. Ummandla wedama lokulahla inkunkuma uxhotyiswe ngezitrato zomhlaba ezicandiweyo ezimbini ukwahlula lo mmandla uphela ube ziindawo ezintathu zokulahla inkunkuma. Isicwangciso secandelo lendawo yokulahla inkunkuma sonyaka wonke siyaqulunqwa kwaye iyunithi yokusebenza ilawulwa ngokweemfuno ezichaziweyo, imibhobho yokuhambisa amanzi avuzayo kumanqwanqwa omhlaba acandiweyo iyanqunyulwa kwaye ivalwe, ukuphambukiswa kwamanzi emvula kunye nogutyulo kuphunyezwa. ubukhulu becala, isixa se-leach eveliswayo siyancitshiswa, kunye nemingcipheko yokusingqongileyo kunye neendleko zemveliso zithotywe ngokufanelekileyo.
Indawo yokulahla inkunkuma isebenzisa oomatshini abakhethekileyo, iibulldozers kunye necompavings ukupheyiva nokuhlanganisa. Ukuxinana kwenkunkuma kuvavanywa rhoqo, ukubunjwa kwenkunkuma kuhlalutywa rhoqo, kwaye i-rolling rolling kunye ne-layer paving yenziwa njengoko kufuneka. I-single-layer paving thickness ilawulwa kwi-0.5 ukuya kwi-1 imitha, kwaye ubukhulu beyunithi bulawulwa kwi-4 ukuya kwi-6 yeemitha.
3, Yigqume yonke imihla ukuze uthintele ukusasazeka kwevumba, kwaye kwangaxeshanye unciphise amanzi emvula ukuba angangeni kwindawo yokulahla inkunkuma, ulawule ukuzala kweengcongconi neempukane, kwaye uthintele ukusasazeka kwevumba.
Ummandla ophantsi kokhuselo kwindawo yokucocwa kwenkunkuma iya kusetyenziswa rhoqo emva kwemini 1.0 HDPE I-membrane igutyungelwe okwethutyana, kwaye zonke iindawo ezingaphandle kobuso bokusebenza ziyi-1.0 mm Ihlanganiswe ngefilimu ye-polyethylene ephezulu, kunye nefilimu yokugubungela kwindawo. engasetyenziswanga ngaphezulu kweentsuku ezili-15 iyadityaniswa kwaye idityaniswe. Amanzi acocekileyo kwifilimu akhutshwa kwi-slope yendalo okanye umsele wokuhambisa amanzi emvula kwindawo, ukwenzela ukunciphisa amanzi emvula ekungeneni kwindawo yokulahla inkunkuma, kunye nokulawula ngokufanelekileyo ukuzala kweengcongconi kunye neempukane kunye nokusasazeka kwevumba. Olu nxulumaniso lubaluleke kakhulu, ngakumbi ukuphambukiswa kwamanzi emvula kunye nogutyulo. Ebusika, siya kugqibezela ukugrunjwa nokugcinwa kwemisele yokuvalela izandyondyo, ukuqinisa iindlela okwexeshana kwiindawo zokulahla inkunkuma, ukuhlola nokulungiswa kweefilim ezigqumayo, ukwakhiwa kweendonga zomhlaba ezicandiweyo, ukufuduswa kunye nokubekwa kweempompo kwangaphambili. Yenza amalungiselelo apheleleyo okomeleza ukhuseleko lwemveliso kunye nokunciphisa imingcipheko yokusingqongileyo ngexesha leemvula. ”
Inxalenye yoqhagamshelwano phakathi kokulahla inkunkuma kunye nethambeka kwindawo yokugcina amanzi ibekwe kwi-50 CM Sand bag umaleko okhuselayo, ithambeka lilawulwa ngezantsi kwe-1: 3, kwaye ulawulo lokuphakama kwemfumba luhlulwe kwi-longitudinal slope kunye nemowudi ye-slope enqamlezayo. Indawo egcwalisiweyo yamkelwa iiMembranes zeHDPE ziphantsi kokhuselo lwaphakathi enyakeni.
4, Akukho kushiyiwa ekubulaweni kweentsholongwane kwindawo. Izitshizi zisetyenziselwa ukongeza ngokuthe ngqo imichiza kwiindlela ezikwisiza, kwaye iinkanunu zomoya zisetyenziselwa ukwenza imisebenzi yokutshiza ngokuzenzekelayo yokubulala iintsholongwane kunye nokuvumba. Kwangaxeshanye, ukugqunywa kweeyunithi zokusebenza kuqiniswa. Okwangoku, impembelelo yokulawula iingcongconi, iimpukane kunye nezivumba kwisayithi zilungile.
Iinethi ezichasene nokubhabha zifakwe kuzo zozibini iziphelo zendawo yokulahla inkunkuma ukuze kuthintelwe ngokufanelekileyo izinto ezibhabhayo.
