Mukuvaka engineering yemazuva ano, dredging chinhu chakakosha chinongedzo, kunyanya muminda yeinjiniya yehurumende uye manejimendi kwezvakatipoteredza.Sechishandiso chinochinjika chekufambisa,hose inoyangararainoita basa rakakosha mukudhirowa mapurojekiti nekuda kwekuiswa kwayo nyore uyekufamba.
Kushanda musimboti wepaipi inoyangarara yekutakura zvinhu
Panguva yekuchera mashandiro, mahosi anoyangarara anobatanidza chikepe chekudonha kusvika panobviswa madhaka (senge chiteshi chekubata zvinhu pamahombekombe kana chikepe chekutakura).Iyo hose inoyangarara inogona kugadzirisa nzvimbo yayo nekufamba kwekuyerera kwemvura kana ngarava, kuderedza kukanganiswa kwezvikepe nemidziyo yekushandisa uye kuchengetedza kuenderera kwekutakura zvinhu.CDSR inoyangarara hose inogona kuenderana neyakasiyana nharaunda yemvura uye mamiriro ekushanda.
Kumhanya kwakakosha
Iyo yakakosha kumhanya ndiyo yakakwana yekumhanyisa iyo inogona kuve nechokwadi chekuti masisitimu akasimba haagadzikane uye kudzivirira yakawandisa kurasikirwa kwesimba kana zvinhu zvinoyerera mupombi.Kana kumhanya kwemvura kwakadzikira pane kumhanya kwakakomba, zvimedu zvakasimba mumatope zvinogara, zvichikonzera kuvharika kwepombi.Kana iyo yekumhanya kwemvura yakakwira kupfuura yakakosha kumhanya, kupfeka pombi uye kushandiswa kwesimba kuchawedzera.
Kuramba kwepombi
Pipeline resistance inoreva kushorwa kunowanikwa pakutakura mvura (sedhaka) mukati mepombi.Kupikisa uku kunokanganisa kuyerera kwemvura uye kumanikidzwa.Izvi zvinotevera zvakati wandei zvakakosha zvinokanganisa kuramba kwepombi:
Kureba kwepombi: Iyo yakareba iyo pombi, iyo yakakura nzvimbo yekukweshana pakati pemvura nemadziro epombi, saka kuramba kwakanyanya.
Pipeline dhayamita: Iyo yakakura iyo dhayamita yepombi, idiki nzvimbo yehukama yekubatana pakati pemvura nemadziro epombi,zvichikonzera kushomeka kwekupokana.
Pipeline zvinhu: Kutsetseka kwepamusoro kwepombi dzezvinhu zvakasiyana zvakasiyana.Pombi yakapfava inoburitsa kushomeka pane dzakakasharara.
Nhamba yezvimedu zviri mupombi: Kuwanda kwezvimedu mumatope, zvidimbu zvakawanda zvinopindirana uye zvinobonderana nemadziro epombi, zvichiita kuti kuwedzere kupikisa.
Zvipingamupinyi mumapaipi: semagokora, mavharuvhu, nezvimwewo, zvikamu izvi zvinokonzeresa kuti mafambiro emvura achinje kana kuyerera kwenzvimbo kuwedzera, zvichibva zvawedzera kukweshera uye kuramba.
Nyaya dzemapfekero
Munguva yekushandiswa kwenguva refu, kudhirowa mapaipi anozosangana nematambudziko akasiyana-siyana ekupfeka nekuda kwekunyanya kwenzvimbo yavo yekushanda.Aya mapfekero anogona kunyanya kukamurwa kuita: mechanical kupfeka kana kukukurwa, uye kemikari corrosion:
Mechanical wear or erosion: Izvi zvinokonzerwa nekukweshana uye kukanganiswa kwezvikamu zvakasimba (sejecha, matombo, madhaka, nezvimwewo) zvinoyerera mukati mepombi pamadziro emukati epombi.Nekufamba kwenguva, izvi zvinoramba zvichiitika zvemuviri zvinotungamira mukurasikirwa zvishoma nezvishoma kwezvinhu pamadziro emukati wepombi, kunyanya munzvimbo dzine mwero wepamusoro wekuyerera senge magokora uye kudzikiswa kwedhayamita, uko kupfeka kunenge kwakanyanya.
Kemikari corrosion: Panguva yekushandiswa, kudhiza mapaipi anogona kusangana nezvimwe zvinoparadza zvinhu.Makemikari aya anobata chemikemikari pamwe nemidziyo yepombi, zvichikonzera kukuvadzwa kwechimiro uye kuparara kwekuita kwepombi.Kemikari corrosion inowanzoita zvishoma nezvishoma, asi kana yakaunganidzwa kwenguva yakareba, inogonawo kukanganisa zvakanyanya pakuvimbika uye hupenyu hwebasa hwepombi.
