Kanda kuri buto iri iburyo
1. Ishingiro ry'inkuta zo munsi y'ubutaka:Kubaka munsi y'ubutaka ku nyubako ndende, inganda, ububiko, amazu y'ubucuruzi n'ay'abaturage. Ishingiro ry'ibirundo (ubwoko bwose bw'inyubako).
2. Ishingiro ry'ibirundo by'ibiraro:Ishingiro ry'ibiraro by'imihanda minini, ibiraro bya gari ya moshi, n'inzira z'umujyi. Ishingiro ry'ibiraro by'imigezi, ibiyaga n'inyanja.
3. Kubaka icyambu:Ifatizo ritwara imizigo ku byambu, aho amato akorera n'aho indege zihagarara. Serivisi zo gutanga ibikoresho biremereye n'imizigo ku byambu.
4. Imishinga y'Ingufu z'Umuyaga n'Ubwubatsi bw'Amato mu Nyanja:Ishingiro ry'ibyuma bikoresha umuyaga byo mu nyanja. Igishushanyo mbonera cy'inyubako zo mu nyanja, imiyoboro yo mu nyanja, imiyoboro yo mu nyanja, inkuta z'inyanja n'ahandi. Mu mazu yo guturamo, kurwanya amazi, kurwanya imiraba, no kwangirika kw'amazi yo mu nyanja.
5. Ubwubatsi Bunini bw'Ibwubatsi:Imisingi ikomeye ifite imiringoti y'umurambararo mugari yo gukora imirimo minini y'ubwubatsi (ingomero, sitasiyo za gari ya moshi, 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. Ibiti cyangwa uduce tw'ibiti bishyirwa hagati y'ibirundo kugira ngo hirindwe ko ingingo zihinduka mu gihe cyo kohereza. Gutunganya ubuso (ni ngombwa): Gusiga irangi ry'umukara, amavuta yo gukumira ingese, firime ya pulasitiki. Ibirundo bya galvanizi bishobora kandi gupfunyikwa muri firime ya pulasitiki y'agateganyo kugira ngo hirindwe ko hejuru hagwa. Hari ipaki yihariye.
2 Amakuru yerekeye ibyo umuntu yaguze:Uburebure busanzwe buri mu bubiko: metero 6, metero 12. Uburebure: busanzwe kandi bwihariye. Biza hamwe na gari ya moshi yo mu mazi n'uburyo bwo kuyikoresha. Bikwiriye gutwara abantu mu mazi, gari ya moshi cyangwa mu muhanda, kandi birakomeye bihagije mu gihe cyo kuyikoresha mu muhanda. Igihe cyo kuyitanga ni iminsi 15-30 nyuma yo kwakira amafaranga, bitewe n'ingano n'ibisobanuro. Bikoreshwa mu kohereza ibicuruzwa ku isi yose, hamwe n'inyandiko yuzuye (Impamyabushobozi y'ikizamini, Urutonde rw'ibipakiye, Inyandiko y'ibicuruzwa).
3 Ingamba zo kwirinda:Ntugakoreshe imigozi cyangwa udukingirizo tudafite udukingirizo kugira ngo uhure n'umuyoboro w'amazi, ibyo bikaba byatera kwangirika kw'imiyoboro. Bika ahantu hakonje, humutse kandi hari umwuka mwiza. Kugira ngo wirinde ingese mbere yo kuyishyiraho. Imizigo minini kandi iremereye igomba kubahiriza amabwiriza yo kohereza ibicuruzwa 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.
