Uhlahlelo lweziBonelelo zeeNgcawu zokunyathela kwamatayara aqinileyo

Ngexesha lokugcinwa, ukuthuthwa kunye nokusetyenziswa kwamathayi aqinileyo, ngenxa yendalo kunye nokusetyenziswa kwezinto, ukuqhekeka kudla ngokubonakala kwipatheni ukuya kumaqondo ahlukeneyo. Izizathu eziphambili zezi zilandelayo:

1.Aging crack: Olu hlobo lokuqhekeka ngokuqhelekileyo lwenzeka xa ivili ligcinwe ixesha elide, ivili libekwe elangeni kunye nobushushu obuphezulu, kwaye ukuqhekeka kubangelwa ukuguga kwerabha yetayara. Kwixesha elizayo lokusetyenziswa kwevili eliqinileyo, kuya kubakho iintanda kwi-sidewall kunye nezantsi kwe-groove. Le meko yinguqu yendalo yerabha yesondo ngexesha lexesha elide kunye nenkqubo yokuvelisa ukushisa.
2.Iintanda ezibangelwa yindawo yokusebenza kunye nemikhwa emibi yokuqhuba: Indawo yokusebenzela isithuthi sincinci, i-radius ejikayo yesithuthi incinci, kwaye nokujika kwi-situ kunokubangela lula ukuqhekeka ezantsi kwepatheni yegroove. I-12.00-20 kunye ne-12.00-24, ngenxa yokulinganiselwa kwendawo yokusebenza yesityalo sensimbi, isithuthi sihlala sidinga ukujika okanye ukujikeleza kwindawo, okubangelwa ukuqhekeka phantsi kwe-groove yokunyathela kwivili ngexesha elifutshane; ukulayishwa kwexesha elide kwesithuthi kudla ngokubangela iintanda kwindlela yokunyathela ecaleni kwedonga ;
3.Ukuqhekeka okubuhlungu: Indawo, imilo kunye nobukhulu bolu hlobo lokuqhekeka ngokuqhelekileyo alulungelelaniswanga, olubangelwa ukungqubana, ukukhupha okanye ukukhuhla izinto zangaphandle ngesithuthi ngexesha lokuqhuba. Ezinye iintanda zenzeke kuphela kumphezulu werabha, ngelixa ezinye ziya kulimaza isidumbu kunye nephethini. Kwiimeko ezinzima, amathayi aya kuwela kwindawo enkulu. Olu hlobo lokuqhekeka luhlala lusenzeka kumsebenzi wamavili oMlayishi wamavili kwizibuko nakwimill yokusila. I-23.5-25, njl., kunye ne-9.00-20, i-12.00-20, njl. yeenqwelo zokuthutha zensimbi ezilahliweyo.
Ngokuqhelekileyo, ukuba kukho ukuqhekeka okuncinci kuphela kumphezulu wepatheni, akuyi kuchaphazela ukhuseleko lwesondo kwaye ingaqhubeka isetyenziswa; kodwa ukuba iintanda zinzulu ngokwaneleyo ukuba zifikelele kwisidumbu, okanye zibangele ukuvaleka okunzulu kwepateni, kuya kuchaphazela ukuqhuba okuqhelekileyo kwesithuthi kwaye kufuneka kulungiswe ngokukhawuleza. buyisela.
