Makina Ogayira a DY-300: Yankho Labwino Kwambiri Lokonzanso Malo Okhala ndi Phula Bwino

Kufunika Kokonzanso Phula Moyenera: Mavuto a Makampani​

Musanafufuze za luso la DY-300, ndikofunikira kumvetsetsa mavuto omwe magulu okonza phula akukumana nawo padziko lonse lapansi. Malinga ndi International Road Federation (IRF), misewu yoposa 40% ya phula padziko lonse lapansi imafunika kukonzanso mkati mwa zaka 5-7 kuchokera pamene inamangidwa, koma njira zachikhalidwe zimavutika kukwaniritsa kufunikira kumeneku. Mwachitsanzo, kugaya ndi manja—pogwiritsa ntchito zida zogwiritsidwa ntchito m'manja—kungangokonza malo okwana mamita 20-30 pa ola limodzi, pomwe makina akale opukutira phula nthawi zambiri amasiya malo osalingana omwe amafunikira kukonzedwanso kwina, zomwe zimawonjezera nthawi ndi ndalama zomwe polojekitiyi imagwiritsa ntchito.​

Komanso, zinyalala za zinthu ndi vuto lalikulu. Kukonzanso malo mwachizolowezi kumachotsa zigawo zonse za phula (nthawi zambiri 5-10 cm) ngakhale 1-2 cm yokha pamwamba yawonongeka, zomwe zimapangitsa kuti zinthu zotayidwa zichuluke ndi 30-40% zomwe zimathera m'malo otayira zinyalala. Izi sizimangowonjezera ndalama zowononga chilengedwe komanso zimawonjezera ndalama zopangira phula latsopano. Kutsekedwa kwa misewu kumawonjezera vutoli: kutsekedwa kwa msewu umodzi pamsewu wotanganidwa kungayambitse kuchedwa kwa magalimoto.

1,200–3,000 pa ola limodzi, malinga ndi bungwe la American Association of State Highway and Transportation Officials (AASHTO). Mavutowa akugogomezera kufunika kwa yankho lomwe limagwirizanitsa liwiro, kulondola, komanso kukhazikika—zomwe ndi zomwe makina opukutira a DY-300 amapereka.​

Mphamvu Zazikulu za DY-300: Ukadaulo Wauinjiniya Wokonzanso​

DY-300 yapangidwa kuti ithetse zofooka za njira zachikhalidwe kudzera mu zinthu zapamwamba zomwe zimaika patsogolo magwiridwe antchito, kulondola, komanso kusavuta kugwiritsa ntchito. Pakati pake, makinawa amagwiritsa ntchito makina amphamvu kwambiri opangidwa ndi hydraulic omwe ali ndi ng'oma yopukutira ya mamita 1.8—yokulirapo kwambiri kuposa ng'oma ya mamita 1.2–1.5 ya omwe akupikisana nawo ambiri. Ng'oma yayikuluyi imalola DY-300 kuphimba malo okwana masikweya mita 120 a phula pa ola limodzi, kuwonjezeka kwa 40–60% poyerekeza ndi makina wamba opukutira. Mwachitsanzo, msewu wa kilomita imodzi wa njira ziwiri (wofunikira masikweya mita 4,000 a kugaya) ukhoza kumalizidwa mu maola 34 okha ndi DY-300, poyerekeza ndi maola 50–60 ndi mitundu yakale.​

Kulondola ndi chizindikiro china cha DY-300. Yokhala ndi GPS-control deep control ndi laser leveling technology, makinawa amasunga kulondola kwa kugaya kwa ±1 mm—kofunika kwambiri kuti atsimikizire kukonzekera bwino kwa pamwamba asanayikenso. Izi zimachotsa kufunikira kokonza pang'ono, kuchepetsa njira za polojekiti ndikuchepetsa kutaya kwa zinthu. Drum yopangira yokha ili ndi mano 80 a tungsten carbide, okonzedwa mozungulira kuti atsimikizire kudula kosalekeza ndikuletsa kung'ambika kwa pamwamba. Mano awa amathanso kusinthidwa, ndi moyo wa maola 50-80 akugwiritsidwa ntchito mosalekeza—kutalika kawiri kuposa mano wamba achitsulo—kuchepetsa ndalama zokonzera komanso nthawi yopuma.​

Zomwe ogwiritsa ntchito akukumana nazo sizinyalanyazidwa. DY-300 ili ndi kapangidwe ka cab-over yokhala ndi zowongolera zoyenera, chiwonetsero cha touchscreen cha mainchesi 10, komanso mawonekedwe a madigiri 360—kuchepetsa kutopa kwa wogwiritsa ntchito pakapita nthawi yayitali. Makinawa ndi ang'onoang'ono (kutalika kwa mamita 6.2, m'lifupi mamita 2.5) ndipo ali ndi radius yozungulira ya mamita 4.8, zomwe zimapangitsa kuti ikhale yoyenera madera okhala ndi misewu yopapatiza kapena ngodya zopapatiza. Pa mapulojekiti akuluakulu, DY-300 ikhoza kugwirizanitsidwa ndi makina apadera otumizira zinthu omwe amanyamula phula lopangidwa m'malole mwachindunji, kuchotsa kufunikira kosungirako zinthu zapakati komanso kukonza magwiridwe antchito.​

Ntchito Zenizeni: Kuwonetsa Kuchita Bwino​

Kuchita bwino kwa DY-300 sikungokhala kongopeka chabe—kwatsimikiziridwa m'mapulojekiti ambiri odziwika bwino okonzanso m'makontinenti osiyanasiyana. Mu 2023, mzinda wa Berlin, Germany, unagwiritsa ntchito makina 12 a DY-300 kukonzanso misewu ya m'mizinda ya makilomita 15 isanachitike chochitika chachikulu chapadziko lonse lapansi. Ntchitoyi idafunikira kupukuta phula la mamita 60,000 lalikulu ndi kuya kwa 2 cm (kuthana ndi ziphuphu ndi ming'alu). Pogwiritsa ntchito ukadaulo wa GPS wa DY-300, gululi linafika pamlingo wofanana pa 98% ya dera lonselo, kuchepetsa zinyalala za zinthu ndi 35% poyerekeza ndi ntchito yawo ya 2021 (yomwe idagwiritsa ntchito makina akale opunthira). Ntchitoyi idamalizidwa m'masiku 28—masabata awiri isanafike nthawi yoikidwiratu—kuchepetsa kusokonezeka kwa magalimoto pakati pa mzinda.​

Ku United States, Dipatimenti Yoona za Mayendedwe ku Texas (TxDOT) idagwiritsa ntchito makina a DY-300 kuti akonze gawo la makilomita 20 la Interstate 35, lomwe linali litakumana ndi mabowo akuluakulu komanso zinyalala chifukwa cha magalimoto ambiri. Dongosolo la DY-300 lokhala ndi mphamvu zambiri linalola kuti lizitha kudutsa mu phula lolimba (lokhala ndi mphamvu kwa zaka 10) popanda kuchepetsa liwiro, pomwe dongosolo lonyamulira katundu linalola kuti zinthu zophikidwa zipitirire kudzaza. TxDOT inanena kuti ntchito ya tsiku ndi tsiku yawonjezeka ndi 42% poyerekeza ndi zida zawo zakale, ndipo phula lophikidwa linabwezeretsedwanso pamalopo (losakanizidwa ndi zinthu zatsopano) kuti lipange 30% ya phula latsopano lomwe limagwiritsidwa ntchito pokonzanso malo—kuchepetsa ndalama za zipangizo ndi $120,000.​

Milandu iyi ikuwonetsa ubwino waukulu wa DY-300: kuthekera kwake kusintha malinga ndi zosowa zosiyanasiyana za polojekiti, kuyambira misewu ya m'matauni mpaka misewu ikuluikulu, ndikupereka zotsatira zokhazikika pankhani ya liwiro, kulondola, komanso kusunga ndalama.​

Kukhazikika: Kugwirizana ndi Zolinga Zachilengedwe Padziko Lonse​

Mu nthawi yomwe ikukulirakulira kuyang'ana kwambiri pa kukhazikika kwa zinthu, DY-300 imadziwika bwino ndi kapangidwe kake kosamalira chilengedwe. Monga tanenera, kupukuta kolondola kwa makinawa kumachepetsa zinyalala za zinthu ndi 30-40% poyerekeza ndi njira zachikhalidwe. Kuphatikiza apo, phula lopukutidwa (lomwe limadziwika kuti recycled asphalt pavement, kapena RAP) silimangotayidwa—lingathe kubwezeretsedwanso kukhala zosakaniza zatsopano za phula. Njira yopukutira ya DY-300 imapanga RAP yokhala ndi tinthu tating'onoting'ono tofanana, zomwe zimapangitsa kuti zikhale zosavuta kuphatikiza mu zosakaniza zatsopano (mpaka 50% RAP nthawi zina), kuchepetsa kufunikira kwa ma aggregates ndi bitumen.​

Kugwiritsa ntchito bwino mphamvu ndi mphamvu ina. DY-300 imagwiritsa ntchito pampu ya hydraulic yosinthika yomwe imasintha mphamvu yotulutsa kutengera katundu, m'malo mogwira ntchito mokwanira mosalekeza. Izi zimachepetsa kugwiritsa ntchito mafuta ndi 15–20% (poyerekeza ndi mapampu osinthika), kuchepetsa mpweya woipa wa carbon ndi pafupifupi matani 0.8 pa maola 100 aliwonse ogwirira ntchito. Makinawa amakwaniritsanso miyezo ya Euro Stage V ndi EPA Tier 4 Final yotulutsa mpweya, kuonetsetsa kuti malamulo okhwima okhudza chilengedwe atsatiridwa.​

Kutsiliza: DY-300 ngati Chothandizira Kukonzanso Phula Mwanzeru​

Makina opera a DY-300 si chida chokha—ndi yankho lathunthu lomwe limathetsa mavuto akuluakulu a kukonzanso pamwamba pa phula: kusagwira ntchito bwino, kusalondola, zinyalala, ndi kuwononga chilengedwe. Mwa kuphatikiza kupanga bwino kwambiri (mamita 120 pa ola limodzi), kulondola kwapadera (± 1 mm kuwongolera kuya), ndi kapangidwe kokhazikika (kuchepetsa zinyalala ndi mpweya woipa), DY-300 imalola mabungwe oyendera ndi makontrakitala kumaliza ntchito mwachangu, pamtengo wotsika, komanso popanda kuwononga chilengedwe.​

Pamene zomangamanga padziko lonse lapansi zikuchulukirachulukira ndipo kufunika kokonza bwino zinthu kukukulirakulira, DY-300 ikuyimira tsogolo la kukonzanso phula—tsogolo lomwe misewu imakonzedwa mwachangu, mosamala, komanso moyenera, kuonetsetsa kuti maukonde oyendera akukhalabe odalirika kwa zaka zambiri zikubwerazi. Kwa bungwe lililonse lomwe likufuna kukonza bwino njira zawo zokonzanso phula, DY-300 si chisankho chokha—ndi yankho labwino kwambiri.
