Phambi kokubeka ifotsholo okanye i-trencher emhlabeni, iikontraka zokunkcenkceshela zifuna isicwangciso esicacileyo sokuqinisekisa ukuba inkqubo yabo yokunkcenkceshela ifakwe ngokuchanekileyo.
Eyokuqala kuluhlu kukucofa u-811 ukuphawula into eluncedo kwipropati. Okulandelayo, ikontraka yokunkcenkceshela kufuneka yazi into abaza kugrumba kuyo.
Ukwazi uhlobo lomhlaba kubalulekile kuba ezinye iindawo zingamatye kunye nezixhobo ezongezelelweyo okanye izixhobo ezinokuthi zifuneke ukungcwaba umbhobho kubunzulu obufanelekileyo. UJason Fuller, umongameli weRed & White Greenery eGeorgetown, eTexas, uthe umhlaba nawo uchaphazela iiyure zamadoda kunye nexesha lokunkcenkceshela elifunekayo ukuthintela ukubaleka kwezi ndawo.
Inkampani ibonelela ngonkcenkceshelo, imbonakalo-mhlaba, i-hardscape, ifanitshala yesiza, i-masonry kunye nokugcinwa kwezorhwebo. I-80% yabathengi beFuller ngabathengi abarhwebayo kwaye i-20% ngabathengi beendawo zokuhlala. Ingeniso yonyaka yenkampani yi-US$11 yezigidi.

Isicwangciso sokunkcenkceshela kufuneka sichaze yonke imiba yesistim, kubandakanywa uhlobo, ubungakanani, kunye nendawo yokuthintela umva; ubungakanani bombhobho we-trunk kunye nendawo jikelele; ubungakanani bevalvu kunye nendawo; ubungakanani becala kunye nendawo jikelele; kunye nohlobo lwentloko yokunkcenkceshela, ubungakanani bombhobho, kunye nendawo.
U-Fuller uthe kufuneka bahlolisise ukuhamba kunye noxinzelelo lwe-flowmeter, eya kutshintsha ukuyila inkqubo yokunkcenkceshela. Umfaki-fakeli kufuneka kwakhona aqwalasele inkcazo yepropati kunye neentlobo ezahlukeneyo zezityalo ezinkcenkceshelwayo.
Umanejala weakhawunti ye-Rain Birdos yekontraka ephezulu uSteve Barendt uthe ukutyelela ipropati phambi kofakelo kuvumela unokontraka ukuba afake iflegi yongquzulwano phakathi kwesicwangciso sobume kunye nesiza kanye.
"Lungisa njengoko kufunekayo ukuze kuqinisekiswe ukuba izinga lokuhamba elikhoyo kwindawo aligqithiswanga," kusho uBarente. Phawula naluphi na utshintsho olwenziwe ngexesha lofakelo kwimizobo njengoko yakhiwe.
Nangona ubunzulu bomsele buya kwahluka ngokwemigaqo yendawo kunye nendawo, kukho izikhokelo eziqhelekileyo. USteve Hoveln, umphathi omkhulu wemveliso yee-rotors, iivalvu kunye nokufakelwa kwi-Hunter Industries, uthe kwiindawo zokuhlala, ubunzulu bombhobho obamkelekileyo bu-8 ukuya kwi-intshi ezili-12.
Wongezelela ukuba kwiiprojekthi zorhwebo, umgca oyintloko uhlala malunga ne-18 ukuya kwi-intshi ye-24 ubunzulu, kwaye umgca wecala ukusuka kwi-valve ukuya kwi-nozzle ifakwe i-shallower, malunga ne-8 ukuya kwi-intshi ye-12.
Nje ukuba inkqubo iphakame kwaye isebenze, unokwenza uhlengahlengiso oluncinci kwinkqubo. (Ifoto ngoncedo lweHunter Industries)
UHoveln uthe xa kusetyenziswa imibhobho enegaskithi kwiipropati zorhwebo, iikontraka kufuneka ziqwalasele amazinga okuqukuqela aphezulu, anokubangela ukonakala kwe-engile ukuba ayiphathwa kakuhle. Ngalo lonke ixesha umbhobho ujikeleza i-90 degrees, i-installer kufuneka yongeze ibhloko ye-thrust, ifake yonke into efanelekileyo kwikhonkrithi okanye ifake ibhloko emva kwayo njengenkxaso.
Emva kokuba i-valve isetyenzisiwe kunye nombhobho uxhunyiwe, qhagamshela i-swing joint kwi-rotor, uze uyilungelelanise ekuphakameni okufanelekileyo. Emva kokongeza i-nozzle, i-installer ingaqala ukulungelelanisa i-rotor kwi-arc efanelekileyo ukuze ugweme ukugqithisa kwiindawo ezinzima okanye izakhiwo. UBarendt uthe unokwenza uhlengahlengiso ngaphambi kokuba usebenze ummandla, kodwa ummandla kufuneka uqhutywe ukuwenza kakuhle.
Umphathi wentengiso yeJain Irrigation uMichael Derewenko uthe nangona ukubuyisela umva kubonakala kulula, kukho indlela efanelekileyo yokungcwaba umbhobho.
UHoveln uthe ukuba ipropati iliwa kwaye umbhobho wePVC ubekwe emseleni, amatye abukhali anganxiba umbhobho ngenxa yokungcangcazela okuncinci, okubangela iingxaki. Ukudala ibhedi yesanti yombhobho-kwaye uyigcwalise ngesanti-iya kuthintela imida ebukhali ekonakaliseni umbhobho.
Gwema ukufaka ii-sprinklers ngokuthe ngqo kwi-PVC enzima, kuba isiseko siya kuphuka xa i-lawn mowers okanye izithuthi zihamba phezu kwazo. Ukuvumela umbhobho ukuba uhambe, i-joint swing esele yenziwe ngaphambili kufuneka isetyenziswe-okanye i-hose enobude obuyi-18 ukuya kwi-intshi ezingama-24, kuxhomekeke kwibakala.
Isalathiso secala kufuneka siqhube ngokuhambelanayo, kungekhona phezulu komnye nomnye kangangoko kunokwenzeka, kuba imigodi esanda kuzaliswa ayinalo amandla anikezelwa ngumhlaba odibeneyo. Ukuba oomatshini abanzima bahamba kwimibhobho emitsha esandul’ ukungcwatywa, le mibhobho inokucudisana, ibangele imigca ebhityileyo ekunzima ukuyibona ukuba yaphuke. UDerewenko uthe unokontraka kufuneka aqinisekise ukuba inkunkuma nobutyobo azishiywa emiseleni.
“Eyona ngxaki inkulu kukushiya inkunkuma nobutyobo emiseleni. Oku akuyi kongeza nje inkunkuma kwindawo, kodwa emva kokufakwa kombhobho, iliwa liza kuwugqobhoza lo mbhobho,” utshilo uDerewenko. “Ngaphezu kokugcina inkunkuma ngaphandle kwemisele, kuhle ukuba kuthathwe umhlaba othambileyo osandula kongezwa ukuqinisekisa ukuba umbhobho uxinene kwaye kufakelwe izitshizi ukuze ulingane kwaye ukhombe kwicala elifanelekileyo.”
U-Barendt uthi ukhetho lombhobho olungachanekanga luyenye impazamo eqhelekileyo. Ngokomzekelo, ikontraki inokufaka iNombolo ye-2 okanye ye-3 ye-nozzle kwi-rotor nganye kwindawo. Ekubeni zonke ii-rotors zikhupha umlinganiselo ofanayo wamanzi kwaye zijikeleze ngesantya esifanayo, i-rotor ye-90-degree iya kufumana kabini inani lamanzi njenge-rotor ye-180-degree kuba igubungela i-arc kabini kunye nekhava enye kanye ngexesha elifunekayo 180 degrees .
"Kwakhona kuthetha ukuba kukho nayiphi na i-rotor ye-360-degree phakathi kweyadi, iya kugubungela kuphela i-arc kanye j kunye ne-rotor ye-90-degree kwikona iya kugubungela amaxesha amane, q uBarente uthe. "Isiphumo kukuba iikona ezimanzi zinamanzi amaninzi kwaye / okanye indawo ephakathi yomile kwaye ingaphantsi kwamanzi."
Isisombululo sale ngxaki kukumisela ubungakanani bombhobho kunye nendawo ngokwezikhokelo zomenzi. U-Barendt wongeze ukuba ukutshintsha ubungakanani bombhobho kuya kutshintsha kwakhona umgama owuphosayo, ngoko ke indawo kunye nobungakanani bunokugqunywa ngobungakanani obuchanekileyo benozzle ukuze kugqunywe intloko ukuya entloko.
Ngokusebenzisa iteknoloji ekumgangatho ophezulu kunye neemveliso, abafakeli banokuqinisekisa ukuba inkqubo ingasetyenziselwa amashumi eminyaka kwaye igcine iindleko kubathengi.
UFuller wongezelela: pEnye yeenzuzo eziphambili zenkqubo yokunkcenkceshela eyilwe ngokufanelekileyo yaza yafakelwa kukuba abathengi banokunkcenkceshela ngokufanelekileyo ipropati yabo, babalondoloze ixesha kwaye okona kubaluleke kakhulu, bonga imali.q
