1. Basa repakati pekutonga gonhi rekuvhara system
Iwo mabasa akasiyana-siyana epakati pekutonga kukiya anoenderana nemabasa eiyo yakajairwa kukiya kuti uwane, saka isu tinofanirwa kutanga tanzwisisa uye kunzwisisa mabasa uye maitiro eiyo yakajairwa kukiya.
(1) Kukiya kwakajairika
Basa rekuvharika kwechivharo ndiyo pfungwa yakajairika yekuvhura nekuvhara basa, iyo yekupa mativi ese emusuwo wemotokari, trunk chivharo (kana muswe gonhi) kuvhura uye kuvhara basa.
Iyo inoratidzirwa nekushandiswa kuri nyore uye akawanda-masuo ekubatanidza. Iyo ndiyo yakajairwa kumisikidzwa yepakati control yekuvhara system, uye zvakare chinodiwa chekuona mabasa ane hukama epakati control yekuvhara system uye inoshanda anti-kuba system.
Iyo yakajairwa yekuvhara basa inozivikanwawo seyo imwe kaviri yekuvhara basa, pahwaro hwayo iyo mbiri yekuvhara basa inogadzirwa. Ndiko kuti, mushure mekuvharwa kwechivharo, injini yekuvhara ichaparadzanisa mubato wegonhi kubva pamagetsi ekuvhara, kuitira kuti gonhi rirege kuvhurwa kubva mumotokari kuburikidza nemubato wegonhi.
Ongorora: Iyo kaviri yekuvhara basa ndeyekuisa yekiyi yekiyi kuburikidza nekiyi, uye kutendeukira kunzvimbo yekukiya kaviri mukati memasekonzi matatu; Kana kuti bhatani rekukiya paremote rinodzvanywa kaviri mukati memasekonzi matatu;
Kana mota yakavharwa kaviri, chiratidzo chekutendeuka chinopenya kuratidza
