Asanaike fosholo kapena trencher pansi, makontrakitala amthirira amafunikira dongosolo lomveka bwino kuti awonetsetse kuti ulimi wawo wothirira wayikidwa bwino.
Yoyamba pamndandanda ndikuyimba 811 kuti mulembe zomwe zimagwiritsidwa ntchito pamalopo. Kenako, wopanga ulimi wothirira ayenera kudziwa zomwe adzakumba.
Kudziwa mtundu wa dothi ndikofunikira chifukwa madera ena akhoza kukhala miyala ndi zida zowonjezera kapena zida zokwirira chitoliro mpaka kuya koyenera. Jason Fuller, pulezidenti wa Red & White Greenery ku Georgetown, Texas, adati nthaka imakhudzanso maola a anthu komanso nthawi yothirira yomwe imafunika kuti zisawonongeke m'maderawa.
Kampaniyo imapereka ulimi wothirira, kukongoletsa malo, hardscape, zida zapamalo, zomangamanga ndi kukonza malonda. 80% yamakasitomala a Fuller ndi makasitomala ogulitsa ndipo 20% ndi makasitomala okhalamo. Ndalama zomwe kampaniyo imapeza pachaka ndi US $ 11 miliyoni.

Dongosolo la ulimi wothirira liyenera kufotokoza mbali zonse za dongosololi, kuphatikizapo mtundu, kukula, ndi malo oletsa kubwerera mmbuyo; kukula kwa chitoliro cha thunthu ndi malo ambiri; kukula kwa valve ndi malo; kukula kwa mbali ndi malo onse; ndi mtundu wa mutu wothirira, kukula kwa nozzle, ndi malo.
Fuller adanena kuti ayenera kuyang'ana kuthamanga ndi kuthamanga kwa flowmeter, zomwe zidzasintha mapangidwe a ulimi wothirira. Woyikirayo ayenera kuganiziranso ndondomeko ya malo ndi mitundu yosiyanasiyana ya zomera zothiriridwa.
Woyang'anira akaunti wamkulu wa kontrakitala wa Rain Birdos, Steve Barendt, adati kuyendera malowo asanakhazikitsidwe kumalola kontrakitala kuwonetsa kusamvana kulikonse pakati pa dongosolo la malo ndi malo enieniwo.
"Sinthani zomwe zikufunika kuti muwonetsetse kuti kuchuluka kwakuyenda m'derali sikudutsa," adatero Barente. Chongani zosintha zilizonse zomwe zachitika pakuyika pazithunzi zomwe zamangidwa.
Ngakhale kuya kwa ngalandeyo kumasiyana malinga ndi malamulo am'deralo komanso malo, pali malangizo ambiri. Steve Hoveln, woyang'anira wamkulu wazogulitsa ma rotor, mavavu ndi zopangira ku Hunter Industries, adati m'malo okhalamo, kuya kwa mapaipi ovomerezeka ndi mainchesi 8 mpaka 12.
Anawonjezeranso kuti ntchito zamalonda, mzere waukulu nthawi zambiri umakhala pafupifupi mainchesi 18 mpaka 24, ndipo mzere wam'mbali kuchokera ku valve kupita kumphuno umayikidwa mozama, pafupifupi 8 mpaka 12 mainchesi.

Hoveln adati akamagwiritsa ntchito mapaipi okhala ndi gaskets pazinthu zamalonda, makontrakitala amayenera kuganizira kuchuluka kwamayendedwe, zomwe zitha kuwononga ngodya ngati sizikugwiridwa bwino. Nthawi iliyonse chitoliro chimazungulira madigiri 90, woyikirayo ayenera kuwonjezera chipika, kukulunga zonse mu konkriti kapena kukhazikitsa chipika kumbuyo kwake ngati chithandizo.
Vavu ikakhazikitsidwa ndipo chitolirocho chikugwirizana, gwirizanitsani kugwedeza kwa rotor, ndiyeno musinthe mpaka kutalika koyenera. Pambuyo powonjezera nozzle, woyikirayo akhoza kuyamba kusintha rotor ku arc yoyenera kuti asawononge malo olimba kapena nyumba. Barendt adanena kuti mutha kusintha zina musanayendetse chigawocho, koma chigawocho chiyenera kuyendetsedwa kuti chiwongolere bwino.
Woyang'anira malonda a Jain Irrigation Michael Derewenko adati ngakhale kubwezera kumbuyo kumawoneka kosavuta, pali njira yoyenera yokwirira mapaipi.
Hoveln adanena kuti ngati katunduyo ndi thanthwe ndipo chitoliro cha PVC chaikidwa mu ngalande, miyala yakuthwa imatha kuvala chitolirocho chifukwa cha kugwedezeka pang'ono, zomwe zimayambitsa mavuto. Kupanga bedi lamchenga la chitoliro - ndikubwezeretsanso ndi mchenga-kuteteza m'mbali zakuthwa kuti zisawononge chitoliro.
Pewani kuyika zowaza mwachindunji pa PVC yolimba, chifukwa maziko amathyoka pamene makina otchetcha udzu kapena magalimoto amadutsa pa iwo. Kuti phokosolo lisunthike, cholumikizira cholumikizira chopangidwa kale chiyenera kugwiritsidwa ntchito - kapena payipi yokhala ndi mainchesi 18 mpaka 24, kutengera kalasi.
Mayendedwe am'mbali ayenera kuyenda mofanana, osati pamwamba pa wina ndi mnzake momwe angathere, chifukwa maenje odzaza posachedwapa alibe mphamvu zoperekedwa ndi dothi lokhazikika. Ngati makina olemera amayenda pamapaipi ongokwiriridwa kumene, mapaipiwo angafinyani, kuchititsa mizera yopyapyala yomwe imakhala yovuta kuwona kuthyoka. Derewenko adati kontrakitala awonetsetsenso kuti zinyalala ndi zinyalala sizisiyidwa m’ngalande.
“Vuto lalikulu ndikusiya zinyalala ndi zinyalala m’ngalande. Izi sizidzangowonjezera zinyalala pamalopo, koma payipi ikadzaikidwa, thanthwe lidzaboola paipiyo,” adatero Derewenko. “Kuphatikiza pakusunga zinyalala kunja kwa ngalande, ndi bwino kutenga dothi lofewa lomwe langowonjezeredwa kumene kuti payipi ipangike ndi kuyikapo zothirira madzi kuti ziwonjezeke ndikuloza kumene.”
Barendt akuti kusankha kolakwika kwa nozzle ndi cholakwika china chofala. Mwachitsanzo, kontrakitala akhoza kukhazikitsa No. 2 kapena No. 3 nozzle pa rotor iliyonse m'dera. Popeza ma rotor onse amatulutsa madzi ofanana ndi kusinthasintha pa liwiro lomwelo, 90-degree rotor idzapeza kawiri kuchuluka kwa madzi monga 180-degree rotor chifukwa imaphimba arc kawiri ndi chivundikiro chimodzi kamodzi pa nthawi yofunikira. 180 madigiri.
"Zikutanthauzanso kuti ngati pali 360-degree rotor pakati pa bwalo, imangophimba arc kamodzi j ndi 90-degree rotor pakona idzaphimba kanayi," adatero Barente. "Zotsatira zake ndikuti ngodya zonyowa zimathiridwa madzi ochulukirapo komanso / kapena malo apakati ndi owuma komanso pansi pamadzi."
Njira yothetsera vutoli ndiyo kudziwa kukula kwa mphuno ndi malo motsatira malangizo a wopanga. Barendt adawonjezeranso kuti kusintha kukula kwa nozzle kumasinthanso mtunda womwe umaponyera, kotero kuti malo ndi kukula kwake zitha kuphimbidwa ndi nozzle yolondola kuti muzitha kuphimba mutu ndi mutu.
Pogwiritsa ntchito ukadaulo wapamwamba kwambiri ndi zinthu, oyika amatha kuonetsetsa kuti makinawo atha kugwiritsidwa ntchito kwazaka zambiri ndikusunga ndalama kwa makasitomala.
Fuller anawonjezera kuti: pUmodzi mwaubwino waukulu wa njira yothirira yokonzedwa bwino ndi yoikidwa ndikuti makasitomala amatha kuthirira bwino katundu wawo, kupulumutsa nthawi komanso chofunika kwambiri, kusunga ndalama.q
Ngati mumakonda nkhaniyi, chonde lembani ku Landscape Management kuti mulandire zolemba zofananira.
