Kudyisa nzira ye kudonhedzwa kunyorera vira

(1) Zvisinei nemubhadharo, isa unotevera kusungunuka zvishoma nezvishoma mutero wekare usati wanyungudika. Kana chibharo chiine ngura yakawanda uye inonamira jecha chikashandiswa zvisirizvo, saizi yechibharanzi uye chimiro chechaji hachina kunaka, muripo wacho hauna kurongedzwa zvine mutsindo uye kuvaka kwacho kwakakomba, kana kana chando chakanyanya kuwedzerwa imwe nguva, “kuvharira” kungangoitika. Chikamu chemvura chinofanira kutariswa kazhinji, uye zambuko rinofanirwa kugadziriswa nekukurumidza kana paine zambuko, uye “yekudarika” inofanira kupwanywa kudzivirira kuumbwa kwe “yekupfuura”. Zvikasadaro, iyo yakanyungudutswa simbi pazasi chikamu ichapisa kupisa, ichikonzera kuora kweyepazasi tira lining, uye kunyange leakage kana kuputika kwesimbi yakanyungudutswa.

(2) Bridge nzira yekurapa: deredza kunyungudika kwazvino kusvika pazasi pe500A; uisimbe netsvimbo yedare; kana isina kuraswa, shandura choto chemagetsi nenzira kwayo uye chengetedza iyo inonyungudika pasimba rakadzika kudzamara simbi yakanyungudutswa yaputsa zambuko kana iyo capping layer;

(3) Mushure mechaji yechaji yanyungudika zvachose, iyo slag inofanira kubviswa ipapo kudzivirira kuumbwa kwe “slag cap”. Kana “slag butiro” ikaumbwa, bvisa simba ipapo nekutyora “slag chivharo” kubva muchoto, zvikasadaro simbi yakanyungudutswa iri pazasi chikamu ichapisa, zvichikonzera kukukurwa kweiyo yepazasi tira lining, uye kunyange kuvuza kana kuputika kwe simbi yakanyungudutswa
