Amathrendi Entuthuko Ekusetshenzisweni Kwemikhava Yemithombo Ehlukahlukene Yokuhlola Emigwaqweni Yasemadolobheni

Izembozo zemithombo yokuhlola ziyingxenye yemigwaqo yasemadolobheni. Enqubweni yokuthuthela emadolobheni, ukwakhiwa komgwaqo kuyindinganiso ebalulekile yokuhlola imiphumela yayo. Kokubili izivakashi zakwamanye amazwe kanye nezakhamuzi zendawo. "Isembozo somgodi olahlekile" yisithunzi, esingeke silethe kuphela ukuphazamiseka kokuhamba, kodwa futhi sibangele izingozi eziwa, ezizoletha umonakalo omkhulu wempahla kanye nokulimala komuntu siqu.Kungabonakala ukuthi ohlelweni lokwakhiwa kwedolobha, indlela yokuklama futhi ukusebenzisa izembozo zemigodi kufanele kube isihloko esibalulekile.

Ukuhlolwa kweShayina kwezembozo zemigodi cishe sekuhlangabezane nezigaba ezintathu, isigaba sokuqala kusukela maphakathi nawo-1990. Ngaphambi kwalokhu, iningi lezembozo zemithombo yokuhlola laliqinisiwe uhlobo lukakhonkolo, olunobukhulu obuhlukene; Ngenxa yokuthi ipayipi likagesi alingcwatshwanga ngokujulile, akukho mbobo yomgodi osetshenziswayo. Maphakathi nawo-1990, inqwaba yezembozo zemigodi kakhonkolo eziqinisiwe zathathelwa indawo izembozo zemigodi yensimbi. Nokho, leli qoqo lezimbobo zomgodi kulula ukugqwala futhi liwe endaweni enomswakama.

Isigaba sesibili ukuphela kweminyaka yawo-1990, iChina yaqala ukuthuthukisa izinga lezembozo zomgodi, futhi yaqala ukukhuthaza ukusetshenziswa kwezembozo zomgodi wensimbi oyindilinga, futhi umgodi womthombo wokuhlola waguqulwa ngokufanele. Ngenxa yokumelana nokugqwala okuhle kwezinto zensimbi esakazwayo, isicaciso esijwayelekile esihlanganisiwe senziwe. Ngakho-ke, ingxenye enkulu yaleli qoqo lezembozo zemithombo yokuhlola isasetshenziswa.

Isigaba sesithathu ukuthi ngemuva kuka-2008, ngokuvela kwezinto ezintsha kanye nobuchwepheshe obusha bokufaka, izinhlobo zesembozo semigodi emisha ikakhulukazi zifaka izembozo zomgodi we-FRP, izembozo zomgodi wensimbi wensimbi kanye nesembozo somgodi oyinhlanganisela, njll. Lezi zimbozo zomgodi zine-anti-corrosion engcono. kanye nemiphumela emelene nokweba kunezinhlobo zezinto zensimbi ekhonjiwe, futhi umsindo wokunyathela komuntu noma ukugingqika kwemoto mncane.

Umkhuba wokusetshenziswa kwesembozo somgodi wensimbi

Izembozo zemithombo ye-cast iron yokuhlola zinethonya elihle ekumelaneni nokugqwala, futhi izembozo eziningi zemigodi zisalungile ngemva kwesikhathi eside zisetshenziswa. Ngakho-ke, isetshenziswa kabanzi. Abanye abakhiqizi bacabanga ukwengeza izindandatho zenjoloba ukuze baphonse izembozo zemigodi yensimbi ukuze banciphise umsindo wabo. Kukhona nabakhiqizi abazokwenza ngcono ukukhiya kwayo ukuze kuxazululwe inkinga yokunganele komsebenzi wokulwa nobugebengu.

Nakuba ukuhlolwa kwezembozo zemithombo kungase kubonakale kungabalulekile kakhulu ezelulekweni nokuphathwa kwedolobha. Kodwa-ke, ingqalasizinda ebalulekile ekuphathweni kwedolobha, ebaluleke kakhulu ebuhleni bedolobha, ukuphepha kwezakhamizi kanye nokuvikelwa kwamapayipi. Ngokuhlela nokuphatha amadolobha, kuyadingeka ukuthi uhlale usebenzisa izinto ezintsha kanye nobuchwepheshe obusha ukuze uhlole izembozo zemithombo futhi uqinise ukuphatha. Ngesikhathi esifanayo, ingakhuthaza ukwelashwa "kobuciko" kwezembozo zomgodi, ukuze wengeze umbala ogqamile ekuphepheni, kalula nasebuhleni bedolobha.

Amagama angukhiye: ukwakhiwa kwedolobha, ukuphathwa komgwaqo, hlola ikhava yomthombo, impilo yasemadolobheni
