Mumapurojekiti ekuwedzera nzira dzepasi pevhu muguta, kuputisa chiteshi ibasa rakakosha uye rine njodzi huru. Semugadziri ane hunyanzvi mukugadzirakuboora matombomichina, tinosuma YT28chibooreso chedombo chemhepo chine makumbo—muchina wepamusoro-soro wakagadzirirwa nzvimbo dzakamanikana uye dzinoda zvinhu nemazvo.YT28Inosanganisa dhizaini yakareruka asi yakasimba ine simba rekutsigira makumbo, ichibvumira vanoishandisa kuti vaise maburi ekuputira nemazvo munzvimbo dzakamanikana. Nzira yayo yekuputira yakanyorova inoderedza guruva, inoderedza kupisa, uye inowedzera hupenyu hwemaburi ekuputira, nepo nzira yekurovera yakatsetseka ichivimbisa simba rekurova rinogara riripo, ichideredza kutsauka panguva yekuputira. Zviratidzo zvakajeka zvekuisa uye makona emakumbo anogadzirisika zvinobatsirawo mukuwana kurongeka kwakanyatsojeka kwegomba, izvo zvakakosha kudzivirira kukuvara kwezvivakwa zvetunnel zviripo uye kuona kuti kuputika kwacho kunodzorwa.

Vasati vatanga kushandisa YT28, nzvimbo zhinji dzekuchera nedzekuchera matuneri dzaishandisa nzira dzekare dzekuboorera matombo kana nzira dzekuboorera nemaoko, izvo zvaiwanzokonzera matambudziko akadai sekutsauka kwemakomba, kudedera kwakanyanya, uye kusvibiswa kweguruva. ​​Matambudziko aya akakonzera mhedzisiro yekubhoorera isina kuenzana, njodzi dzinogona kuitika, uye nguva refu yepurojekiti. Mushure mekuchinjira kuYT28, vashandi vakataura nezvekuvandudzwa kukuru: kurongeka kwekuboorera kwakawedzera neinenge 40%, nekukanganisa kwekuroorera makomba kwakadzikira kusvika mukati me3 cm mumatombo akaomarara. Sisitimu yekuboorera yakanyorova yakavandudzawo mamiriro ekushanda nekuderedza huwandu hweguruva riri mumhepo neanopfuura 80%, zvichiwedzera kuona uye kuchengetedzeka kwekufema kwevashandi. Muchirongwa chekuwedzera chiteshi chemetro munguva pfupi yapfuura munzvimbo yemaguta yakavakwa nevanhu vakawanda, YT28 yakagonesa makontrakita kupedzisa chikamu chekuboorera kwekuwedzera mavhiki maviri nguva isati yasvika, pasina zviitiko zvekukuvadzwa kwemadziro etuneri ari pedyo. Kugara kwenguva refu kwemuchina uyu kwakaratidzwa sezvo wakaramba uchishanda zvakanaka kuburikidza nekushanda nguva dzose munzvimbo dzine hunyoro, dzinokuvadza pasina kusakara kwakanyanya.

Kune vanogadzira zvivakwa nenyanzvi dzekugadzira tunnel, YT28 inomiririra zvinopfuura kungoboorera chete—ichi chishandiso chakanyatsojeka chinoenzanisa simba, kutonga, uye kuchengetedzeka kwemushandisi. Dhizaini yayo inoratidza ruzivo rwemakore akawanda rwefekitori yedu mukugadzira mhinduro dzekuchera matombo ekushandisa pasi pevhu. Tinopa rutsigiro rwakazara rwehunyanzvi, kusanganisira nhungamiro panzvimbo yekumisa makumbo, kugadzirisa frequency yekukanganisa, uye kugadzirisa sisitimu yekurova yakavharwa nemvura. Chigadziko chega chega chinoedzwa pasi pemamiriro ekunze akavharirwa vasati vasvika kuti vave nechokwadi chekuti vakavimbika. Sezvo maguta pasi rese achiwedzera network dzavo dzekufambisa pasi pevhu, kudiwa kwemidziyo yekuboorera yakarurama, inoshanda, uye yakachengeteka kuri kuramba kuchikura. Chiboorera chematombo chemakumbo cheYT28 chinosangana nechido ichi nekushandura mabasa akaoma ekuputisa kuita mashandiro anogoneka, anofungidzirwa—pakupedzisira zvichibatsira mukuvandudzwa kwezvivakwa zvemaguta zvakachengeteka, nekukurumidza, uye zvine mari yakawanda.
