Ebunjiniyela bomphakathi, izinqwaba zensimbi zibalulekile ukuze kube nezakhiwo ezinzile, ezihlala isikhathi eside—futhiizinqwaba zeshidi lensimbizigqame ngokuguquguquka kwazo. Ngokungafani nezinqwaba zensimbi zesakhiwo (ezigxile ekudluliseni umthwalo), izinqwaba zamashidi zihamba phambili ekugcineni inhlabathi/amanzi ngenkathi zisekela imithwalo, ngenxa “yokukhiya” kwazo. Ngezansi umhlahlandlela olula wezinhlobo zazo, osayizi abavamile, kanye nokusetshenziswa okungokoqobo.
Izinqwaba zamashidi zihlukaniswa zibe izigaba ezimbili eziyinhloko zokukhiqiza: ezigoqiwe ezishisayo nezibandayo, ngayinye inohlobo lwe-U kanye nengxenye ye-Z.
Inqwaba Yeshidi Lensimbi Eligoqiwe Elishisayo
Yenziwe ngokushisisa insimbi ngaphezu kuka-1,000°C bese igingqika ibe yisimo, lezi zinqwaba ziqinile, zihlala isikhathi eside, futhi zilungele amaphrojekthi amakhulu, esikhathi eside.
I-Hot RolledU-Type Inqwaba Yeshidi: I-cross-section yayo ethi “U” (i-parallel flange + web) inikezela ngokufakwa kalula—ngisho nasemhlabeni ominyene. Inokuqina okuhle kwezinhlangothi, ilungele ukugcina izindonga noma ukwesekwa kokumba. Isikhala sangaphakathi se-U-shape singabuye sigcwaliswe ngokhonkolo ukuze uthole amandla engeziwe.
I-Hot RolledZ Inqwaba Yeshidi Lesigaba: Ifana no-“Z,” ama-flange ayo abheke ezinhlangothini eziphambene, nezingidi emaphethelweni angaphandle. Lokhu kudala ububanzi obusebenzayo obubanzi, ngakho-ke ama-piles ambalwa amboza indawo (izindleko zokusika). Imelana namandla aqinile aseceleni, okuyenza ibe yinhle ekumbiweni okujulile noma umsebenzi osebeni lomfula.
Izinqwaba Zeshidi Lensimbi Eyakheke Ngokubandayo
Kubunjwe ngensimbi eyisicaba ekamelweni lokushisa (akukho ukushisa), lawa alula, ashibhile, futhi angcono kumaphrojekthi amancane/esikhathi esifushane (yize aqinile kangako kunokugoqwa okushisayo).
Inqwaba Yeshidi Lohlobo Olwakhiwe Ngokubandayo: Izacile kunezinhlobo ze-U ezigoqiwe ezishisayo, kulula ukuyihambisa nokuyifaka. Isebenzisele izindonga zokugcina zesikhashana, uthango lwasengadini, noma imigoqo emincane yezikhukhula—elungele amaphrojekthi wesabelomali.
Inqwaba Yesigaba Seshidi Esakhiwe Ngokubandayo: Yabelana ngomumo othi “Z” kodwa ivumelana nezimo. Ilungele izindawo zesikhashana (isb, imingcele yokwakha) njengoba kulula ukuyisusa futhi ivumelane nokunyakaza okuncane komhlaba.

Osayizi bancike ezidingweni zephrojekthi, kodwa lawa amazinga embonini:
U-Type Inqwaba Yeshidi:
400mm×100mm: I-Compact yezikhala eziqinile (izindonga ezincane zokugcina, ukuhlelwa kwengadi).
400mm×125mm: Mude emisebenzini ephakathi nendawo (ukumbiwa kwezindawo zokuhlala, imigoqo emincane yezikhukhula).
500mm×200mm: Umsebenzi onzima wezindawo zokuhweba (ukumba okujulile, izindonga ezihlala njalo).
Z Inqwaba Yeshidi Lesigaba: 770mm×343.5mm iyona ehamba phambili. Idizayini yayo ebanzi ihlanganisa izindawo ezinkulu, futhi iqine ngokwanele ukuqinisa usebe lomfula noma ukulawula izikhukhula ezinkulu.
Izinqwaba zamashidi ensimbi zikhanya kumaphrojekthi omhlaba wangempela afana nalawa:
I-Riverbank Guardrails: Izinhlobo ze-U/Z ezishisayo ziqinisa amabhange ukuze amise ukuguguleka. Amandla azo amelana namandla amanzi, futhi izingidi ezixhumene zigcina inhlabathi isendaweni.
Izindonga (Ezigciniwe kanye Nomngcele): I-U-izinhlobo ezibandayo zisebenza ezindongeni zokuhlala; Izinhlobo ze-U/Z ezigoqiwe ezishisayo zibamba izindonga zentengiso (isb, ezizungeze izitolo ezinkulu). Amalokhi awenza angangeni manzi, avimbele ukulimala kwamanzi.
Ukulawula Izikhukhula: Izinhlobo ze-Z ezishisayo zakha imingcele eqinile yezikhukhula; ezakheke ngokubanda ziyashesha ukuzifaka ezimeni eziphuthumayo (isb., ukuqubuka kwesiphepho). Zombili zigcina amanzi ephuma ngokuphumelelayo.
Kungani Khetha Izinqwaba Zeshidi Lensimbi?
Iqinile (i-hot-rolled ihlala iminyaka engu-50+), kulula ukuyifaka, futhi iyonga isikhathi eside. Ngezinhlobo/osayizi abaningi, balingana cishe nanoma iyiphi iphrojekthi yokugcina noma yokulayisha.
Ngokuzayo lapho ubona udonga olubambayo noma umgoqo wezikhukhula, cishe lusekelwa ukwethembeka kwezinqwaba zamashidi ensimbi!
