Michina yekugaya yeDY-300: Mhinduro Yekupedzisira Yekugadzirisa Nzvimbo yeAsphalt Zvakanaka

Kukurumidzira Kwekugadzirisa Asphalt Zvinobudirira: Matambudziko Eindasitiri​

Tisati taongorora kugona kweDY-300, zvakakosha kunzwisisa matambudziko ari kusangana nemapoka ekugadzirisa asphalt pasi rose. Sekureva kweInternational Road Federation (IRF), migwagwa yeasphalt yepasi rose inodarika 40% inoda kugadziriswa mukati memakore mashanu kusvika manomwe ekuvakwa, asi nzira dzechinyakare dzinonetsa kuzadzisa kudiwa uku. Semuenzaniso, kugadzira migwagwa nemaoko—zvichienderana nezvishandiso zvinobatwa nemaoko—kunogona kungogadzira 20-30 square metres yenzvimbo paawa, nepo michina yekare yekugadzira migwagwa inowanzosiya nzvimbo dzisina kuenzana dzinoda kucheneswa kwakawedzerwa, zvichiwedzera nguva yepurojekiti nemari.​

Uyezve, marara ezvinhu inyaya huru. Kugadzirisa zvinhu nenzira yechinyakare kunobvisa matanda ese easphalt (kazhinji 5–10 cm) kunyangwe 1–2 cm yepamusoro chete yakakuvara, zvichiita kuti zvinhu zvakaraswa zviwande ne30–40% zvinozopedzisira zvaiswa mumarara. Izvi hazvingokwidzi mari yezvakatipoteredza chete asiwo zvinokwidza mari yekugadzira asphalt itsva. Kuvharwa kwemigwagwa kunowedzera dambudziko iri: kuvharwa kwemugwagwa mumwe chete mumugwagwa wakabatikana kunogona kukonzera kunonoka kwemari yemotokari.

1,200–3,000 paawa, sekureva kweAmerican Association of State Highway and Transportation Officials (AASHTO). Matambudziko aya anoratidza kudiwa kwemhinduro inoenzanisa kumhanya, kururama, uye kugarika—izvo chaizvo zvinopihwa nemuchina wekugaya weDY-300.​

Kugona Kukuru kweDY-300: Hunyanzvi hweUinjiniya hweKugadzirisa​

DY-300 yakagadzirirwa kugadzirisa zvipingamupinyi zvenzira dzechinyakare kuburikidza nezvinhu zvakawanda zvepamusoro zvinopa kukosha kwekushanda zvakanaka, kunyatsorongeka, uye nyore kushandisa. Pachinyanya, muchina uyu unoshandisa sisitimu yehydraulic ine torque yakakwira yakabatana nedhiramu rekugaya rakafara mamita 1.8—rakafara zvikuru kupfuura madhiramu e1.2–1.5-mita evazhinji vanokwikwidza. Dhiramu iri rakafara rinobvumira DY-300 kufukidza asphalt inosvika 120 square metres paawa, kuwedzera kwekubudirira kwe40–60% zvichienzaniswa nemichina yekugaya yakajairwa. Semuenzaniso, mugwagwa une migwagwa miviri wemakiromita imwe (unoda 4,000 square metres yekugaya) unogona kupedzwa mumaawa makumi matatu nemana chete neDY-300, zvichienzaniswa nemaawa makumi mashanu–60 nemamodeli ekare.​

Kunyatsorongeka ndeimwe yezviratidzo zveDY-300. Yakashongedzerwa neGPS-guided depth control uye laser leveling technology, muchina uyu unochengetedza kudzika kwekugaya kwakarurama kwe±1 mm—zvakakosha pakuona kuti pamusoro pacho pakagadzirwa zvakaenzana usati waisazve pamusoro. Izvi zvinobvisa kudiwa kwekukwenenzverwa kwechipiri, kuderedza matanho epurojekiti uye kuderedza marara ezvinhu. Drum rekugaya pacharo rine mazino etungsten carbide makumi masere, akarongwa nenzira inotenderera kuti ave nechokwadi chekucheka nguva dzose uye kudzivirira kubvaruka pamusoro. Mazino aya anogonawo kutsiviwa, ane hupenyu hwemaawa makumi mashanu kusvika makumi masere ekushandiswa nguva dzose—hurefu hwakapetwa kaviri pane mazino esimbi akajairwa—zvichideredza mari yekugadzirisa uye nguva yekushanda.​

Ruzivo rwemushandisi haruna kukanganiswa. DY-300 ine dhizaini yekabhini ine ergonomic controls, 10-inch touchscreen display, uye 360-degree visibility—zvinoderedza kuneta kwemushandisi panguva yekushanya kwenguva refu. Muchina uyu wakamanikanawo (kureba mamita 6.2, 2.5 metres hupamhi) uye une 4.8 metres turnover radius, zvichiita kuti ive yakakodzera kunzvimbo dzemaguta dzine migwagwa yakamanikana kana makona akaomarara. Kune mapurojekiti makuru, DY-300 inogona kubatanidzwa nehurongwa hwakatsaurirwa hwekutakura zvinhu hunoisa zvakananga asphalt mumarori, zvichibvisa kudiwa kwekuchengetedza pakati uye kuwedzera kufambira mberi kwekushanda.​

Mashandisirwo Enyika Chaiyo: Kuratidza Kushanda Zvakanaka​

Kushanda kweDY-300 hakusi kungofungidzira chete—kwakasimbiswa mumapurojekiti akawanda epamusoro ekugadziriswa kwemakondinendi. Muna 2023, guta reBerlin, Germany, rakashandisa michina gumi nemiviri yeDY-300 kugadzirisa migwagwa yemaguta iri makiromita gumi nemashanu pamberi pechiitiko chikuru chepasi rose. Chirongwa ichi chaida kugayiwa kwenzvimbo ine asphalt ine hurefu hwemamita zviuru makumi matanhatu (60,000 square metres) nehupamhi hwe2 cm (kugadzirisa matombo nemakomba). Vachishandisa tekinoroji yeGPS yeDY-300, timu iyi yakawana hurefu hwakafanana munzvimbo iyi, ichideredza marara emidziyo ne35% zvichienzaniswa nechirongwa chavo cha2021 (chakashandisa michina yekare yekugayiwa). Chirongwa ichi chakapedzwa mumazuva makumi maviri nemasere—mavhiki maviri pamberi penguva yakatarwa—zvichideredza kukanganiswa kwemotokari pakati peguta.​

MuUnited States, Dhipatimendi reKufambisa reTexas (TxDOT) rakaisa michina yeDY-300 kugadzirisa chikamu chemakiromita makumi maviri cheInterstate 35, icho chakanga chave nemakomba akanyanya nekuda kwemotokari dzakawanda. Sisitimu yeDY-300 ine torque yakakura yakaita kuti ikwanise kugaya neasphalt yakaoma (yakamanikidzwa kwemakore gumi) isina kunonoka, nepo sisitimu yekufambisa yakagonesa kurodha zvinhu zvakagayiwa nguva dzose. TxDOT yakashuma kuwedzera kwe42% mukubudirira kwezuva nezuva zvichienzaniswa nemidziyo yavo yekare, uye asphalt yakagayiwa yakashandiswazve panzvimbo yacho (yakasanganiswa neaggregate itsva) kugadzira 30% yeasphalt itsva yaishandiswa pakugadzirisa - kuderedza mitengo yezvinhu ne $120,000.​

Izvi zvinoratidza mukana mukuru weDY-300: kugona kwayo kugadzirisa zvinodiwa zvakasiyana-siyana zvepurojekiti, kubva kumigwagwa yemumaguta kusvika kumigwagwa mikuru, uye kupa mhedzisiro inoenderana maererano nekumhanya, kunyatsorongeka, uye kuchengetedza mari.​

Kugara kwenguva refu: Kuenderana neZvinangwa zveNyika Dzepasi Pose zveNzvimbo Yakatikomberedza​

Munguva yekuwedzera kwekutarisa pakuchengetedza nharaunda, DY-300 inoonekwa seyakagadzirwa zvakanaka. Sezvambotaurwa, kugadzira nemazvo kwemuchina uyu kunoderedza marara echinhu ne30–40% zvichienzaniswa nenzira dzechinyakare. Uyezve, asphalt yakagayiwa (inozivikanwa sereclaimed asphalt pavement, kana kuti RAP) haingoraswi chete—inogona kudzokororwa kuita misanganiswa mitsva yeasphalt. Maitiro ekugaya eDY-300 anogadzira RAP ine saizi yakaenzana, zvichiita kuti zvive nyore kuisanganisa nemisanganiswa mitsva (kusvika ku50% RAP mune dzimwe nguva), zvichideredza kudiwa kwevirgin aggregates nebitumen.​

Kushanda zvakanaka kwesimba ndeimwe simba. DY-300 inoshandisa pombi ye hydraulic inochinja-chinja inogadzirisa simba rinobuda zvichienderana nemutoro, pane kuti ishande nesimba rakazara nguva dzose. Izvi zvinoderedza kushandiswa kwemafuta ne15–20% (zvichienzaniswa nemapombi anofambisa mafuta asingachinji), zvichideredza kuburitswa kwecarbon neanenge matani 0.8 pamaawa zana ekushanda. Muchina uyu unosanganawo neEuro Stage V neEPA Tier 4 Final emissions standards, zvichiita kuti pave nekutevedzwa kwemitemo yakasimba yezvakatipoteredza pasi rose.​

Mhedziso: DY-300 senzira yekuvandudza Asphalt zvine hungwaru​

Muchina wekugaya weDY-300 hausi kungova mudziyo chete—imhinduro yakazara inotarisa matambudziko makuru ekugadzirisa pamusoro peasphalt: kusashanda zvakanaka, kusanyatsorongeka, marara, uye kukanganisa nharaunda. Nekubatanidza kugadzirwa kwepamusoro (120 square metres paawa), kunyatsojeka kwakanyanya (±1 mm kudzika), uye dhizaini inochengetedza (marara akaderera uye kusvibiswa), DY-300 inobvumira masangano ekufambisa nemakambani ekugadzira mapurojekiti kuti apedzise mapurojekiti nekukurumidza, nemutengo wakaderera, uye nekuchengetedzwa kushoma kwenharaunda.​

Sezvo zvivakwa zvepasi rose zvichiri kukura uye kudiwa kwekugadzirisa kwakanaka kuri kuwedzera, DY-300 inomiririra remangwana rekugadzirisa asphalt—remangwana apo migwagwa inogadziriswa nekukurumidza, zvakachengeteka, uye nenzira inochengetedza, zvichiita kuti network dzekufambisa dzirambe dzakavimbika kwemakumi emakore anotevera. Kune chero sangano rinoda kugadzirisa maitiro aro ekugadzirisa asphalt, DY-300 haisi sarudzo chete—ndiyo mhinduro yekupedzisira.
