Iiprojekthi zeendlela zangaphantsi komhlaba zasezidolophini zihlala zijongene neemeko ezixubileyo zejografi: iileya ezithambileyo, iileya eziqinileyo, ukungena kwamanzi.YT28iphatha olu tshintsho kakuhle ngamandla empembelelo alawulekayo kunye nokuhambelana kwebhithi eguquguqukayo.

 

Ukuhambelana kwayo nokugrumba ngamanzi kunceda ukugcina amanqanaba othuli aphantsi, nto leyo ibalulekileyoiishafti zemetro ezinomoya omncinci.

 

Ngokusekelwe ekusebenzeni kakuhle kokugrumba kwe-YT28 air leg rock drill, i-YT28 ngokuqinisekileyo iya kuba nendawo kwimigodi, ukugcinwa kwamanzi, ukwakhiwa kweendlela, imithombo yamanzi, kunye neeprojekthi zokugrumba amatye. I-YT28 isebenzisa uyilo oluncinci noluqinileyo, olunenzuzo kakhulu kwiindawo ezincinci nezivaliweyo. Kwindawo evaliweyo yomgodi we-subway shaft, i-YT28 nganye yenzelwe ngokubeka phambili ukusetyenziswa kwabaqhubi, okulula ukuba abasebenzisi bayisebenzise kwaye kunciphisa ukudinwa ngexesha lemisebenzi yokugrumba ixesha elide. Oku akupheleli nje ekuziveni kokusetyenziswa; Oku kunxulumene ngakumbi nokhuseleko lwemigodi kunye nokunciphisa ilahleko zemali ezibangelwa lixesha elide lokugrumba. Ukukwazi ukulungisa amandla okuchaphazela kwenza abasebenzi bakwazi ukutshintsha ukusuka ekutyumzeni i-granite eqinileyo baye kumhlaba othambileyo, onobumba obuninzi ngaphandle kokutshintsha oomatshini, ukunciphisa inkqubo yokutshintsha oomatshini kunye nokwenza lula umjikelo wonke wokugrumba.

 

Ukongeza, ukugxininiswa kokumba amanzi kuzise iingenelo zokucinywa kothuli kunye nokukhuselwa kwendalo. Ngokufaka amanzi emngxunyeni, inkqubo ayinakubamba nje kuphela amasuntswana anobungozi, kodwa ikwapholisa i-drill bit, yandisa kakhulu ubomi bayo benkonzo kwaye inciphise ukuphindaphindeka kokutshintshwa kwe-drill bit. Oku kunciphisa iindleko zokusebenza kwaye kunciphisa ixesha lokungasebenzi kakuhle. Kubaphathi beprojekthi abaphetheyo, i-YT28 ibonelela ngenzuzo ephambili. Iqinisekisa ukuba ukumba kwenziwa ngesantya esihambelanayo nesiqikelelweyo, igcina iprojekthi isendleleni kwaye ikhusela impilo yabasebenzi. Olu dibaniso lokuqina koomatshini, ubukrelekrele bokusebenza, kunye nendawo yokusebenza ecocekileyo kwenza i-YT28 ibe liqabane elibalulekileyo ekwakheni imithambo ebalulekileyo yothutho exhomekeke kuyo izixeko zanamhlanje.
