Xa umthengi weprojekthi endithumelela ingxelo yobungakanani obuneemingxuma zomhlaba ezingama-200 kuyo, into abayithelekisayo phantse isoloko ixabisa iyunithi. Ndiyaqonda ukuba kutheni - lelona nani kuphela elikwiphepha. Kodwa emva kweminyaka eli-12 yokuhlolwa kwemingxuma yokuthunyelwa kwiiprojekthi zokumisa umhlaba kumazwekazi amane, ndingakuxelela ukuba ixabiso leyunithi lelona nani lincinci kweli thelekiso. Ixabiso lilonke lokufakelwa kwemingxuma yomhlaba yingqokelela yabaqhubi abahlanu - imveliso, imithwalo, umsebenzi wokufakelwa, ukulingana komthwalo, kunye nobomi benkonzo - kwaye ikhonkrithi iphumelela kanye enye yazo kwisicelo esiqhelekileyo sokumisa umhlaba. Ndiza kubeka amanani okwenyani eklasini yomthwalo etafileni (ukusuka kwi-EN 124 kunye nemithombo ye-AASHTO), ndigcine icala lemali lithembekile ngaphandle kokuqamba uluhlu lwamaxabiso, kwaye ndikunike isixhobo sokugqiba endisisebenzisayo kwisicatshulwa sam.
TL;DR — Abaqhubi beendleko abahlanu, babekwe ngokwezinga abathengi ababaphosela ngalo
- Umthwalo ngumgca webhajethi ongathethiyo.Ndibukele umsantsa wempahla ususa inzuzo yexabiso lekhonkrithi phantse kuyo yonke iodolo yokuthumela ngaphandle: umngxuma wekhonkrithi owenziwe kwangaphambili unobunzima obuphindwe kaninzi kunowe-polymer, ngoko ke kwiodolo yemingxuma engama-200, ukuthunyelwa nokuphathwa kwempahla rhoqo kudlula umsantsa wexabiso leyunithi.
- Umsebenzi wokufakelwa uthanda i-polymer ngokwendlela eyilwe ngayo.Ndifaka umngxuma wepolymer onomntu omnye, akukho crane, kwaye akukho mshini wokuwugalela; umngxuma wekhonkrithi udinga izixhobo zokuphakamisa, izinto zokulala, kwaye rhoqo ixesha lokwenza ifom kwindawo yokusebenza.
- Ubunzima beklasi yomthwalo bubetha ukuqhayisa kweklasi yomthwalo.Ndiyaqaphela ukuba i-EN 124 class A15 (15 kN test load) igubungela iindawo zabahambi ngeenyawo kwaye i-B125 (125 kN) igubungela iindlela zabahambi ngeenyawo kunye neendawo zokupaka iimoto — apho kuhlala khona imingxunya yokuhlola umhlaba; ndibiza amandla e-D400 kwindawo yokuvavanya ukuba imali ichithekile.
- Ubomi benkonzo buxhomekeke kwimigaqo ethile, hayi ithemba.I-EN 124-6:2015 ifuna ukuba izigqubuthelo ze-PP/PE/PVC-U zihlale zizinzile kwi-UV, kwaye imingxunya yethu ye-polymer inobomi boyilo obungaphezu kweminyaka engama-50 — imifantu yekhonkrithi, i-spall, kwaye idlakaza ukuqina kwayo kumhlaba orhabaxa.
- Ikhonkrithi isaphumelela ndaweni ithile.Ndishiya izithuthi ezinkulu ngabom (i-AASHTO H-20: umthwalo wamavili angama-16,000 lb, ubungqina obungama-40,000 lb) kwikhonkrithi elungisiweyo kwangaphambili — kwaye ndiyayingqina le nto ngeenkcukacha ezingezantsi.
Oko Kwenziwa Yingxunya Yomhlaba (Kwaye Kutheni Oko Kugqiba Izibalo Zeendleko)
Umngxuma womhlaba — obizwa ngokuba ngumngxuma wokuhlola okanye igumbi lokufunxa umhlaba — yindawo yokufikelela phezu kwentonga yomhlaba okanye uqhagamshelo lwegridi: ikhusela ijoyinti, igcina indawo yovavanyo yomile ngokwaneleyo ukuba ivuleke, kwaye ivumela iqela lakho lokulungisa ukubamba umvavanyi kwi-electrode minyaka le. Imingxunya yethu inceda ukumisa umhlaba, ukhuseleko lombane, ukuthintela ukuphazamiseka, kunye nokufunxa umhlaba ochasene nokuma komhlaba kumandla, oololiwe, ulwakhiwo, imigodi, iikhemikhali, kunye neendawo zoshishino — naphi na apho uqhagamshelo lomhlaba lufuna ukujongwa ngexesha langempela. Ndigxininisa lo msebenzi kuba ulungisa imfuneko yomthwalo: indawo yokuvavanya umhlaba ikwicala, kwindlela yabahambi ngeenyawo, kwikona yeyadi, okanye kumda olungiselelwe umhlaba — indawo yabahambi ngeenyawo. Phantse andikaze ndibone umntu ehleli kwindlela yelori.Ngenxa yokuba umsebenzi womngxuma kukufikelela nokukhusela endaweni yokuthwala umthwalo ngokwesakhiwo, udidi lomthwalo oludingayo ngokwenene ludla ngokuba yi-A15 okanye i-B125 — kwaye loo nto inye ibumba ngokutsha lonke uthelekiso lweendleko ze-polymer-versus-concrete.
Amanani omthwalo, ukusuka kwimigangatho ngokwayo
Ndicaphula iiklasi zomthwalo kwimithombo ephambili kuba "umthwalo onzima" awuthethi nto ngaphandle kwenombolo. Ndithatha ezi klasi ngqo kwisakhelo saseYurophu, i-EN 124-1:2015, esizichaza ngomthwalo wovavanyo: A15 kwi-15 kN kwiindawo ezisetyenziswa ngabahambi ngeenyawo nabakhweli beebhayisekile kuphela, i-B125 kwi-125 kN yeendlela zokuhamba ngeenyawo kunye neendawo zokupaka iimoto, i-C250 kwi-250 kN yeendlela zomphetho, kunye ne-D400 kwi-400 kN yeendlela zokuhamba ngeenqwelo. Inxalenye ethile yezinto ze-thermoplastics,EN 124-6:2015 yeekhava zePP, PE, kunye nePVC-U, isebenza kufakelo lweklasi A15 kunye neB125 kwaye ifuna ukuba yonke into yenziwe ngezinto ezizinzileyo ze-UV. Nditshintsha isigama eMntla Melika: ngokweIsikhokelo sokulinganisa umthwalo somenzi we-EJ, ii-castings ezingezizo ezothutho zibamba ukuya kuthi ga kwi-2,500 lb, umthwalo olula ugubungela i-2,500–16,000 lb, kwaye umlinganiselo owaziwayo we-AASHTO H-20 uthetha umthwalo wevili we-16,000 lb kunye novavanyo lobungqina be-40,000 lb kwi-pad ye-9×9 intshi. Ndiyimaphu yokuziqhelanisa nombutho wezorhwebo wase-UK.Isikhokelo seBPF Pipes Group malunga namagumbi okuhlola iplastikiIindawo zabahambi ngeenyawo zeQela loku-1 zifuna i-A15 (uvavanyo lwe-15 kN), iindlela zabahambi ngeenyawo zeQela lesi-2 kunye neendawo zokupaka iimoto zifuna i-B125 (uvavanyo lwe-125 kN), kunye neklasi yendlela yokungena ye-A35 phakathi kweendlela zabucala zokungena.
Apho ikhonkrithi ifuneka ngokwenene
Ndingumphathi wentengiso womenzi we-polymer pit okuxelela ukuba uza kuyithenga nini ikhonkrithi, ngoko ke funda oku ngokunyaniseka. Inkcazo yebhidi kamasipala ka-2024 ephethwe nguUkwakhiwa kwe-LCS kwiprojekthi yaseBerkeleyibonisa indlela iinjineli ezinika ngayo izinto: ii-handholes kunye neebhokisi ezindleleni kunye neendlela zendlela ezicwangcisiweyo kufuneka zenziwe ngesamente eqingqiweyo kwi-AASHTO H-20; iindawo zokungena kunye neendawo zokupaka ezinezithuthi ezinzima ezingezizo ezomntu zinokuba yisamente yepolymer kwi-SCTE 77 Tier 15; iindawo zabahambi ngeenyawo zithatha iTier 8; kwaye iindawo zabahambi ngeenyawo kuphela zingasebenzisa iiyunithi zefiberglass ezivavanyiweyo ukuya kwi-3,000 lbf (13,345 N). Ndifuna uqaphele ipateni: izinto zilandela ityesi yomthwalo, kwaye ityesi yomthwalo ilandela ithrafikhi. Ukuba umngxuma wakho womhlaba umi apho iilori ziqhuba khona ngabom, ndiza kukuxelela ukuba uthenge ityesi eqingqiweyo eqingqiweyo eqingqiweyo - eyethu ayisiyomveliso ifanelekileyo kwaye neyunithi yepolymer yomnye umntu ayiyo.
Umqhubi 1 — Ixabiso leyunithi: Inani elinye elithelekiswa ngumntu wonke
Nantsi indawo endigcina kuyo isithembiso sam sokungazenzi uluhlu lwamaxabiso: amaxabiso e-pit ahamba neemarike ze-resin, iimarike zesamente, ubungakanani be-odolo, kunye nendawo ekuyiwa kuyo, ngoko ke nayiphi na imali yedola endiyiprintileyo iya kuba yimali engapheliyo kwikota. Ndixelela abathengi into engashukumiyo: isakhiwo. Ndibona i-polymer ebunjiweyo kunye nemigodi emincinci yekhonkrithi elungisiweyo ihleli kwindawo efanayo ebanzi yexabiso lefektri-isango lefektri-ingango yemveliso-ingango yekhonkrithi ngamanye amaxesha iphantsi kubungakanani bempahla, i-polymer ngamanye amaxesha iphantsi kubungakanani obubunjiweyo. Ndicaphule zombini ezivela kwifektri enye (umgca wethu we-AF-N0658 usebenzisa ii-PVC kunye neendidi zekhonkrithi), kwaye ndixelela abathengi into efanayo ngalo lonke ixesha: ixabiso lefektri-isango lijikeleze inye kwezintlanu, kwaye ngumjikelo obaluleke kakhulu kwiiodolo zokuthumela ngaphandle.
Umqhubi 2 — Impahla: Apho ikhonkrithi ilahlekelwa yi-oda yokuthumela ngaphandle
Ndiphatha ubunzima njengesiphelo kwi-logistics. Umngxuma wekhonkrithi owenziwe kwangaphambili onomthamo ofanayo unobunzima obuphindwe kaninzi kunobunzima bomngxuma we-polymer obunjiweyo - oko kukuthi, i-physics, kungekhona ukuthengisa, kwaye uhamba ngokukhawuleza kwinqanaba ngalinye lomthwalo: iiyunithi ezimbalwa kwi-pallet nganye, ii-pallet ezimbalwa kwisikhongozeli ngasinye, umthwalo ophezulu wolwandle ngeyunithi nganye, iilori ezinzima ngaphakathi, kunye nemida yokuphatha ngesandla kuzo zombini iziphelo. Ii-polymer pits zethu zithunyelwa ngaphakathi kwiphakheji yangaphakathi, iibhokisi, kunye nee-pallets ezivela kwizibuko laseNingbo okanye eShanghai - isicwangciso sokupakisha esiyilwe malunga nobunzima obulula - kwaye kwi-odolo yeprojekthi eqhelekileyo ye-200-to-500-pits, ukonga umthwalo kuphela kudlula umahluko wamaxabiso avela kwifektri.Ngenxa yokuba imithwalo yolwandle ihlawuliswa ngokwevolumu kunye neebhrakhethi zobunzima endaweni yexabiso lemveliso, ukuthunyelwa kwemveliso enzima kwihlabathi liphela yeyona ndlela ikhawulezayo yokutshabalalisa inzuzo yayo yexabiso.Ndisoloko ndisebenzisa ezi zibalo kwiingcaphuno zokwenyani, yiyo loo nto umbuzo wam wokuqala kumthengi othelekisa iindleko ungazange uthi “lixabiso lini abalicaphuleyo” kodwa uthi “iyunithi enye inobunzima buni.”
Umqhubi 3 — Ufakelo: Umntu Omnye Xa Ethelekiswa Nabasebenzi
Ndiyayeka ukuba nobuchule kwindawo: uthelekiso alusondelanga. Ndichaza ukufakwa kwepolymer ngolu hlobo: gquma ipokotho, beka umngxuma phezu kwe-electrode, yenza uqhagamshelo, buyisela umva, gqibile — umsebenzi omnye, izixhobo zesandla, akukho kulinda. Ndibukela ukufakwa kwekhonkrithi kongeza ukuphakamisa (izandla zesibini ubuncinane, uncedo loomatshini olubi kakhulu), umaleko wokulala olungiselelweyo, izihlalo ezicokisekileyo ukuphepha imithwalo eqhekezayo eqhekeza umphetho, kwaye akukho xolelo ukuba umngxuma uwela ugobile. Ndiphinda-phinda umahluko wabasebenzi kwi-200-pit rollout kwaye ukufakwa kuba lelona xabiso likhulu elilawulekayo kwiprojekthi.Ngenxa yokuba umsebenzi wokufakelwa ulingana nenani lemingxuma ngelixa ubunjineli bungenzi njalo, inzuzo yokufaka ipolymer ngeyunithi nganye iya ikhula ngakumbi njengoko iprojekthi ikhula.Ibinzana lethu ledatha lale nto licacile ngabom — “kulula ukulifaka, lixabiso liphantsi” — kwaye liyasinda xa lidibana neendawo zemisebenzi yokwenyani.
Umqhubi 4 — Ukulingana koMthwalo: Yeka ukuhlawulela amandla ongenakuwasebenzisa
Ndibona lo mqhubi ethatha indawo yepolymer ngendlela abathengi abangayixabisi ngayo. Ukuba indawo yakho yokuvavanya ikwindawo yabahambi ngeenyawo, iinkcukacha ezichanekileyo yi-A15; indawo yokupaka iimoto, i-B125. I-EN 124-6 ikhona ngokuchanekileyo ukuqinisekisa izigqubuthelo ze-thermoplastic kwezo klasi zimbini, kunye nokuqina kwe-UV okunyanzelekileyo. Ndibiza inzuzo yekhonkrithi — amandla e-D400 xa iqiniswe ngentsimbi — amandla ongenakuwasebenzisa kwindawo yokuvavanya umhlaba, kwaye ndiyala ukuvumela abathengi ukuba bahlawule. Isifundo sisebenza macala omabini: ukuba umngxuma omnye kuyilo lwakho uhlala kwindlela yokuhambisa, loo mngxuma — kwaye yiloo mngxuma kuphela — ufumana isigqubuthelo esilinganisiweyo. Ndigcinele abathengi imali yokwenyani ngokwahlulahlula iodolo yemingxuma engama-200 kwiiyunithi zepolymer ezili-195 kunye neeyunithi ezilinganisiweyo ezi-5 emva kokujonga isicwangciso sabo sendlela.
Umqhubi 5 — Ubomi beNkonzo: Ixabiso elifika kwiBakala le-12
Ndifunde ukuba iziseko ezingcwatyiweyo ziyasilela ngokuzolileyo. Ndibona imingxunya yekhonkrithi iqhekeka phantsi kwemijikelo yokuqandisa, i-spall apho ii-chloride zifikelela khona ekuqiniseni, kwaye zilahlekelwa ziingcingo zazo zentsimbi okanye zentsimbi ngenxa yokugqwala kumhlaba omanzi, onoburhalarhume beekhemikhali apho iinkqubo zokumisa umhlaba zigxile khona. Umngxuma we-PP, PE, okanye we-PVC-U ozinzileyo yi-UV awunayo i-reinforcement to crème, awunayo i-samente matrix to spall, kwaye - ngokwemigaqo yezinto ze-EN 124-6 - iphakheji ye-UV emiselweyo yenxalenye eveziweyo. Sibeka umgca wethu we-polymer earth pit kwinqanaba elingaphezulu kweminyaka engama-50 yobomi benkonzo, kwaye ndiwuthatha loo nto njenge-conservative kwiyunithi ebekwe kwindawo efanelekileyo.Ngenxa yokuba umngxuma womhlaba ukhusela icandelo elinye, kufuneka ufikelele kulo ubomi bonke benkqubo — uqhagamshelo lwe-electrode — umngxuma ongasebenziyo kwirhafu yonyaka we-12 rhoqo ngonyaka oseleyo wenkqubo yokumisa umhlaba ngomsetyenzana wokutshintsha.
Ndixabisa ukutshintshwa njengokwemba, umngxuma omtsha, ukujonga ukuphinda kuqhagamshelwe kwenye indawo, kunye nokutyelela abasebenzi; ukuphepha umjikelo omnye wokutshintshwa kubaluleke ngaphezu kwayo nayiphi na impikiswano malunga namaxabiso esango lomzi-mveliso.

Isixhobo Sokwenza Izigqibo Endisisebenzisayo Kwisicatshulwa Sam
Phendula imibuzo emine malunga neprojekthi yakho kwaye ingqiqo iyaqhuba ngokwayo. Ndiyilakhile le nto kwi-interactive checker engezantsi - ulandelelwano olufanayo endihamba ngalo kwiifowuni zesicatshulwa.
Isikhethi sezinto zoMngxuma woMhlaba (iCost-Driver Logic)
Oko Sikwakhayo Nendlela Esikuthumela Ngayo
Zethuumngxuma wokuhlola izinto zeplastikiumgca (imodeli ye-AF-N0658) ubunjwe nge-PVC okanye iindidi zekhonkrithi — ndizigcina zombini kuba ukubonelela ngokunyaniseka kuthetha ukubonelela ngezinto ezifanelekileyo ngengingqi nganye — zilinganiswe iminyaka engaphezu kwama-50 phantsi komhlaba, ngenkonzo ye-OEM kunye ne-ODM yobukhulu kunye nophawu oluthile lweprojekthi. Kubathengi abakha iinkqubo zokufikelela ngokupheleleyo, ukufanisaizigqubuthelo zomhlaba zegumbi leplastiki elineplastiki eninzisithwala uyilo lwegridi olulinganiswe ngumthwalo, kwayeIsiciko se-PVC esisikwere somngxumaivala izithuba zokuhlola ezinkulu; usapho lonke luhlala phantsi kwekhaya lethuudidi lomngxuma womhlabaSivelisa iziqwenga ezingama-50,000 ngenyanga phantsi kwe-ISO 9001 ngenkqubo yethu ye-QC enamasango amathandathu — i-IQC, i-IPQC, i-first-piece, i-mass-production, i-OQC, kunye ne-FQC checks — kwaye yonke iyunithi ishiya ipakethe yangaphakathi kunye neebhokisi kunye neepallet, ezifakwe kwisikhongozeli eShanghai okanye eNingbo. Sibamba ixesha eliqhelekileyo lokukhokela kwiintsuku ezili-10 kwiziqwenga zokuqala ezili-100, kwaye ndixoxisana ngemiyalelo yomthamo ngokuchasene neshedyuli yeprojekthi.
Amanqaku asentsimini: Iimpazamo zokuthenga endizibukela abathengi beziphinda
Ndivula iipatheni ezintathu emva kwezigqibo ezininzi zemigodi yomhlaba ezibizayo. Ipatheni yam yokuqala kukubala ngaphezulu kweenkcukacha: lonke ityala lezinto libhalwa kwimeko embi kakhulu yendlela, ngoko ke ii-pits ezingama-200 zinomlinganiselo womthwalo ofunekayo ezintlanu kuzo. Ipatheni yam yesibini kukuba buthathaka kwempahla: ispredishithi yokuthelekisa ima esangweni lomzi-mveliso, kwaye ityala lesikhongozeli lifika njengento engalindelekanga. Ipatheni yam yesithathu kukubaleka ubomi bonke: ukhetho olungabizi kakhulu ukuthenga lufumana udumo ngokuqina olungenalo kumhlaba orhabaxa, kwaye umjikelo wokutshintsha ufika kumgca webhajethi yomnye umntu emva kweminyaka elishumi.Ngenxa yokuba imingxuma yomhlaba yinto encinci enombhobho omkhulu — uvavanyo ngalunye lokumisa umhlaba luxhomekeke kuyo amashumi eminyaka — imizuzu emihlanu echithwayo kumiselwa isicwangciso sendawo lelona nyathelo libalulekileyo ekuthengweni kwayo yonke.
Imibuzo Ebuzwa Rhoqo: Imibuzo Yokuthengwa Kwemingxunya Yomhlaba Evela Kubathengi Beprojekthi
Yintoni esetyenziselwa umngxuma womhlaba kwinkqubo yokumisa umhlaba?
Ndiyichaza njengesixhobo sokulungisa inkqubo yakho yokumba umhlaba: umngxuma uhlala phezu kwentonga yomhlaba okanye uqhagamshelo lwegridi, ukhusela ijoyinti kumhlaba, ukugaleleka kwamanzi, kunye nomonakalo ongengozi, kwaye unika abasebenzi bakho indawo yokufikelela ecocekileyo yokuvavanya ukumelana rhoqo kunye nomsebenzi wokudibanisa kwakhona. Ngaphandle kwayo, uvavanyo ngalunye lonyaka luqala ngefosholo. Imingxunya yethu isebenza ngokufakwa komhlaba, ukukhuselwa kombane, ukuthintela ukuphazamiseka, kunye nokufakelwa okuchasene nokuma komhlaba kwiindawo zamandla, oololiwe, ulwakhiwo, imigodi, kunye neendawo zoshishino.
Ngaba umngxuma womhlaba wepolymer unamandla ngokwaneleyo okungena kwindlela yokungena?
Kwizithuthi, ewe — i-EN 124 framework rates B125 igubungela umthwalo wovavanyo lwe-125 kN kwiindawo zokuhamba ngeenyawo nakwiindawo zokupaka iimoto, kwaye i-BS ISO 15398 yongeza iklasi ye-A35 kwiindlela zokungena zabucala. Kwizithuthi eziqhutywa ngabom neziphindaphindwayo zeelori, hayi — loo msebenzi ungowekhonkrithi elungisiweyo kwangaphambili kwi-AASHTO H-20 (umthwalo wevili we-16,000 lb kunye novavanyo lobungqina be-40,000 lb). Ndiqala ndijonga ityala lendlela, kwaye kwiindawo ezixutyiweyo ndahlulahlula iodolo ukuze i-pit nganye ithwale kanye umlinganiselo ofunekayo kwindawo yayo.
Yeyiphi ebiza kancinci xa iyonke - imigodi yomhlaba eyenziwe nge-polymer okanye nge-concrete?
Xa ixabisa iyonke, i-polymer iphumelela kwisicelo esiqhelekileyo sokufunxa umhlaba, kwaye andizukuyikhohlisa ngokuchaneka ngamaxabiso eyunithi aqanjiweyo. Ulwakhiwo oluthembekileyo: amaxabiso esango lomzi-mveliso akwindawo enye; i-polymer emva koko iphumelela kwimpahla (inxalenye encinci yobunzima), ukufakwa (umfaki omnye endaweni yeqela), kunye nobomi benkonzo (iminyaka engaphezu kwama-50, akukho monakalo okanye ukubola). Ikhonkrithi iphumelela kuphela apho amandla ayo omthwalo efunekayo ngokwenene - iindlela zendlela ezicwangcisiweyo - okanye apho umthengisi wengingqi olungiselelwe kwangaphambili esusa ngokupheleleyo imithwalo kwi-equation.
Ihlala ixesha elingakanani i-polymer earth pit phantsi komhlaba?
Sibeka umlinganiselo womgca wethu kwiminyaka engaphezu kwama-50 yobomi benkonzo. Ingqiqo yezinto ezibonakalayo iyakuxhasa oku: Imigodi ye-PP, i-PE, kunye ne-PVC-U ayinazo izixhobo zentsimbi zokugquma kwaye ayinayo i-matrix yesamente yokuqhekeka okanye yokuqhekeka, kwaye i-EN 124-6 iyalela izinto ezizinzileyo ze-UV kwiindawo eziveziweyo. Kwimihlaba emanzi, enetyuwa, okanye eqandisiweyo — iindawo ezichanekileyo ezigugisa ikhonkrithi ngokukhawuleza — iyunithi yepolymer yileyo ihlala ikruqula, kwaye into oyifunayo kwiziseko ezingcwatyiweyo.
Yeyiphi ireyithingi yomthwalo endifanele ndiyichaze kumngxuma wokuhlola umhlaba?
Ndiyidwelisa kwibhokisi yendlela: A15 (uvavanyo lwe-15 kN) kwiindawo zabahambi ngeenyawo kuphela, B125 (125 kN) kwiindawo zokuhamba ngeenyawo nakwiindawo zokupaka iimoto, A35 kwiindawo zokungena zabucala, kwaye ikhonkrithi ebekwe kwangaphambili kwi-H-20 kuphela apho iilori zidlula ngabom. Isikhokelo sokukhetha i-BPF Pipes Group sisebenzisa iqela elifanayo. Uninzi lweendawo zokuvavanya umhlaba zikwindawo ye-A15 okanye ye-B125 - jonga isicwangciso sendawo yakho ngaphambi kokuba uvumele nabani na akuthengisele amandla endlela kwindawo yokuvavanya.
Ngaba imingxuma yomhlaba yepolymer ingasetyenziswa kumhlaba oselunxwemeni okanye odlamkileyo ngamakhemikhali?
Ewe — ndiyazincoma apho. Umoya ogudle ulwandle kunye nomhlaba onetyuwa okanye oneasidi uhlasela imingxuma yekhonkrithi kabini: i-matrix spalls kunye nentsimbi efakwe ngaphakathi iyabola. Imingxuma yepolymer ezinzileyo ye-UV ayinabungozi, yiyo loo nto ubudlelwane bethu bokuthumela ngaphandle obude bukwiiprojekthi zonxweme kunye nezemigodi apho imingxuma yekhonkrithi yayingaphumeleli kwangethuba. Tshatisa umlinganiselo wekhava kunye necala lendlela kwaye imingxuma iya kuhlala ixesha elide kuneshedyuli yokugcinwa ebhalwe kuyo.
Ipakishwa njani imingxuma yomhlaba ize ithunyelwe njani ukuze ithunyelwe kwamanye amazwe?
Ukupakisha kwethu okuqhelekileyo kokuthumela ngaphandle kukupakisha ngaphakathi kunye neebhokisi kunye neepallet, ezifakwe kwisikhongozeli eShanghai okanye eNingbo port — ubunzima obuphantsi bomgca wepolymer yiyo eyenza ukuba isicwangciso sokupakisha sisebenze kakuhle, kwaye sisixhobo esifanelekileyo kwicala lakho lolwandle. Ixesha lokufumana isaphulelo lithatha iintsuku ezili-10 ngobuninzi ukuya kuthi ga kwiinxalenye ezili-100, kunye nobuninzi beprojekthi obukhulu obucwangcisiweyo ngokuchasene nenkqubo yakho yokufaka. Ndibandakanya uluhlu lokupakisha, ubunzima obupheleleyo, kunye nesicwangciso sokulayisha kunye nesicatshulwa ngasinye ukuze iqela lakho lezothutho likwazi ukuxabisa umthwalo ngaphambi kokuba uzibophelele.
Amaxabiso eprojekthi yemigodi engama-200 ngamanani okwenyani?
Ndithumelele inani leemigodi, imephu yendlela edlula kuyo indawo, kunye nezibuko lendawo oya kuyo. Ndiza kuphendula kungekapheli usuku olunye ngengcebiso yezinto ezibekwe kwindawo ethile kunye nekowuteshini yeendleko ezifikelelweyo zethu.imingxunya yokuhlola i-polymer— kubandakanywa nezibalo zempahla, azilibaleki.Qala incoko kwiphepha lethu lonxibelelwano →
