Kanda kuri buto iri iburyo
1. Ishingiro ry'inkuta zo munsi y'ubutaka:Imisingi miremire y'inyubako ndende, inganda, ububiko, inyubako z'ubucuruzi n'iz'abaturage. Imisingi y'ibirundo (ikwiriye ubwoko bwose bw'inyubako).
2. Ishingiro ry'ibirundo by'ibiraro:Imisingi itwara imizigo ku biraro by'imihanda minini, ibiraro bya gari ya moshi, n'inzira zo mu mijyi. Imisingi ikoreshwa ku biraro by'imigezi, ibiyaga, n'inyanja.
3. Kubaka icyambu:Ishingiro ryikoresho ritwara imizigo ku byambu, aho amato akorera, n'aho bashyira imizigo. Ibikoresho biremereye n'ibikoresho byo gutwara imizigo ku byambu.
4. Imishinga y'Ingufu z'Umuyaga n'Ubwubatsi bw'Amato mu Nyanja:Ishingiro ry'ibyuma by'umuyaga byo mu nyanja. Igishushanyo mbonera gishyigikira urubuga rwo mu nyanja, imiyoboro y'amazi yo mu nyanja, inkuta z'inyanja, nibindi. Kurwanya amazi yo mu nyanja, kurwanya amazi yo mu nyanja, no kurwanya ingese zo mu nyanja.
5. Ubwubatsi Bunini bw'Ibwubatsi:Imisingi miremire ifite imiringoti minini y'umurambararo w'imishinga minini y'ubwubatsi (nk'ingomero, sitasiyo zo munsi y'ubutaka, n'imiyoboro y'amazi). Inkunga ku mashini n'imitwaro y'inganda.
1) Ibiro by'ishami - Inkunga y'abavuga Icyesipanyoli, ubufasha bwo kwishyura ibicuruzwa bya gasutamo, n'ibindi.
2) Hari toni zisaga 5.000 z'ibicuruzwa, bifite ingano zitandukanye
3) Igenzurwa n'imiryango yemewe nka CCIC, SGS, BV, na TUV, hamwe n'ibipfunyika bisanzwe byo mu mazi
1 Paki:Imigozi y'icyuma yoroshye kuyifata. Ibyuma by'imbaho cyangwa uduce duto bishyirwa hagati y'uduce kugira ngo hirindwe ko ingingo zihinduka mu gihe cyo kuyitwara. Gutunganya ubuso (ni ngombwa): Gusiga irangi ry'umukara, amavuta yo gukumira ingese, agapira ka pulasitiki. Ibirundo bya galvanize bishyushye bishobora gutwikirwa na gapira karinda by'agateganyo kugira ngo hirindwe gushwanyagurika ku buso. Hari uburyo bwo gupfunyika bukozwe mu buryo bwihariye.
2 Gutanga:Uburebure busanzwe bw'ibicuruzwa: metero 6, metero 12. Biboneka mu burebure bwihariye. Biza na Gari ya moshi n'umuhanda. Bikwiriye gutwara abantu mu mazi, gari ya moshi cyangwa mu muhanda. Igihe cyo kubigezaho ubusanzwe ni iminsi 15-30 nyuma yo kwakira amafaranga, hakurikijwe ingano n'ibisobanuro. Bikwiriye koherezwa mu mahanga ku isi yose, hamwe n'inyandiko yuzuye (icyemezo cy'igenzura, urutonde rw'ibipakiye, inyemezabwishyu y'imizigo).
3 Amabwiriza yo kwirinda:Ntugakoreshe imigozi cyangwa udukingirizo tudafite udukingirizo kugira ngo ukore ku buso bw'umuyoboro kugira ngo wirinde ko umuyoboro wangirika. Bika ahantu hakonje, humutse kandi hafite umwuka mwiza, wirinde ingese mbere yo kuyishyiraho. Kohereza ibintu biremereye cyane kandi birengeje urugero, nyamuneka wuzuze amabwiriza yo kohereza ibintu mu gace utuyemo.
Q1: Ni ikiIkirundo cy'umuyoboro w'icyuma wa ASTM A252?
Ni imiyoboro y'icyuma ikoreshwa mu gucukura, gucukura ishingiro, ibiraro, icyambu, n'aho imirimo y'ubwubatsi ibera.
Q2: Ni ibihe bipimo biri mu bubiko?
Icyiciro cya 1, 2, na 3 - Gr.1 ikoreshwa mu gupakira ibintu byoroshye, Gr.2 ikoreshwa mu nyubako rusange, Gr.3 ikoreshwa mu kumisha ibintu bikomeye.
Q3: Ni zingana zihe ufite?
Ingano: 4"–24" (114–610mm)
Ubunini bw'urukuta: 5–25mm
Uburebure: 6–12m cyangwa ukurikije ibyo ukeneye
Q4: Ese ibi birundo bisizwe irangi?
Yego - Ifite icyuma gishyushye cya galvanize, gitwikiriwe na epoxy cyangwa gisizwe irangi kugira ngo kirinde ingese.
Q5: Ni ubuhe bwoko bw'icyemezo gitangwa?
Imigozi yose irimo iy'igenzura rya MTC irahari.
Q6: Ni gute imirundo yoherezwa?
Bifatanye n'imishumi y'icyuma
Gutanga ibintu byinshi cyangwa amapaleti y'ibiti.
Ifite imipfundikizo yo ku mpera no kuvura ingese
Q7: Ese nshobora kubona ingano zihariye?
Yego dushobora kuguha uburebure, uburebure n'amanota byihariye ku mushinga wawe.
Q8: Ni gute wahitamo amanota akwiye?
Hashingiwe ku bushobozi bwo gutwara, imiterere y'ubutaka n'uburyo bukoreshwa mu bwubatsi. Inkunga ituruka ku buhanga.
Q9: Igihe gisanzwe cyo gutanga ni ikihe?
Iminsi 15–30, bitewe n'ingano n'uburyo byahinduwe.
