1. Nheyo dzeMadziro ePasi pevhu:Nheyo dzakadzika dzezvivakwa zvirefu, mafekitori, matura, zvivakwa zvemabhizinesi nedzimba dzekugara. Nheyo dzakaita sedura (dzakakodzera marudzi ese ezvivakwa).
2. Nheyo dzeBridge Pile:Nheyo dzinotakura mutoro dzemabhiriji emigwagwa mikuru, mabhiriji ezvitima, uye nzira dzemumaguta. Dzorerai nheyo dzemabhiriji anoyambuka rwizi, dhamu, uye mabhiriji anoyambuka gungwa.
3. Kuvakwa kweChiteshi:Nheyo dzinotakura mutoro dzezviteshi zvechiteshi, nzvimbo dzekugadzira ngarava, uye mapuratifomu echiteshi. Midziyo inorema uye nzvimbo dzekutakura zvinhu zvechiteshi.
4. Mapurojekiti eMagetsi eMhepo neMainjiniya eMugungwa:Nheyo dzematurbine emhepo ari kunze kwegungwa. Dhizaini yekutsigira mapuratifomu ari kunze kwegungwa, mapaipi ari kunze kwegungwa, madziro egungwa, nezvimwewo. Kuramba mafungu, kuramba mafungu, uye kuramba ngura mugungwa.
5. Mainjiniya Ekuvaka Akakura:Nheyo dzakadzika dzine mirwi yakakura yemapurojekiti makuru einjiniya yezvivakwa (senge madhamu, zviteshi zvepasi pevhu, uye matunnel). Rutsigiro rwemichina yeindasitiri nemitoro yezvivakwa.
1) Hofisi yeBazi - rubatsiro rwevanhu vanotaura chiSpanish, rubatsiro rwekubvisa zvinhu kubva kumitero, nezvimwewo.
2) Matani anopfuura 5,000 emutoro aripo, ane saizi dzakasiyana-siyana
3) Inoongororwa nemasangano ane chiremera akadai seCCIC, SGS, BV, uye TUV, ine mapurasitiki akajairika anokodzera kufamba mugungwa
1. Kurongedza:Tambo yesimbi kuti zvive nyore kubata.
Zvidhinha zvematanda kana kuti dunnage zvinoiswa pakati pemakomba kudzivirira kukuvara panguva yekutakura.
Kudzivirira pamusoro (sarudzo): Pendi nhema, mafuta anodzivirira ngura, kana mipumburu yepurasitiki.
Mapombi esimbi anonyudzwa nekupisa anogona kunge aine firimu rekudzivirira kwenguva pfupi kudzivirira kukwenya pamusoro.
Kurongedza kwakagadzirirwa munhu kunowanikwa kana wakumbira.
2. Kutumirwa:Kureba kwemidziyo yakajairika: mamita matanhatu nemamita gumi nemaviri. Kureba kwakagadzirwa nemaoko kunowanikwa kuti kuenderane nezvinodiwa neprojekiti yako.
Yakakodzera kutakura vanhu mugungwa, njanji, kana mugwagwa.
Nguva yekutumira inowanzo kuve mazuva gumi nemashanu kusvika makumi matatu mushure mekusimbiswa kwekubhadhara, zvichienderana nehuwandu uye zvakatsanangurwa.
Yakakodzera kutengeswa kunze kwenyika pasi rose, ine magwaro akazara (chitupa chekuongorora, runyorwa rwezvinhu zvinoiswa, gwaro rekutakura zvinhu).
3. Kubata Nhungamiro:Shandisa crane kana forklift ine zvitsigiso kana zvitsigiso kudzivirira kushanduka kwepombi.
Chengeta munzvimbo inotonhorera, yakaoma, ine mhepo yakanaka kudzivirira ngura usati waisa.
Kana zvinhu zvakakura/zvakawandisa, ndapota tevedzera mitemo yekutumira zvinhu munharaunda.
1. Chii chinonziMapombi esimbi eASTM A252 Giredhi 3?
Mapombi esimbi eASTM A252 egiredhi rechitatu mapaipi esimbi akasungirirwa kuti ashandiswe senheyo yakadzika pasi pezvivakwa, mabhiriji, madoko, uye mainjiniya ekunze. Kune maitiro maviri ekushongedza mapaipi aya: mapaipi ekushongedza arc akasungirirwa pasi pesimbi (SSAW) kana mapaipi ekushongedza arc akasungirirwa pasi pesimbi (LSAW/EFW).
2. Zviyero zvipi uye urefu hupi huripo?
Dhayamita yekunze: 219 mm - 3000 mm (XXL/hukuru hwedhayamita hombe huripo) Ukobvu hwemadziro: 6-40 mm. Kureba kwemidziyo yakajairika ndeyemamita matanhatu nemamita gumi nemaviri, uye kureba kwakakosha kunogona kupihwa kana ukakumbira.
3. Ndezvipi zvinodiwa zvechigadzirwa uye hunhu hwemakanika?
Chiyero Chezvinhu: ASTM A252 Giredhi 3
Simba reKubereka: ≥345 MPa
Simba rekudhonza: 455~620 MPa
Kureba: ≥20%%
4. Ndingawana here zvitupa zvemhando yepamusoro uye mishumo yekuongorora?
Ehe, mapaipi ese esimbi ane chitupa cheISO 9001. Magwaro ese anodiwa anosanganisira mishumo yevamwe vanhu kubva kuSGS, BV kana rimwe sangano rinozivikanwa.
5. Mapombi esimbi anoiswa sei?
Inosunga mapaipi esimbi nebhandeji resimbi uye inoiparadzanisa nematanda pasina kukuvara. Mapendi ekudzivirira/kuputira kana/uye kurapwa kwepamusoro-soro kwataurwa pamusoro apa kunokurudzirwa zvichienderana nepakeji yekutumira. Mapakeji akagadzirwa anowanikwa.
6. Inguva yekutumira inguvai?
Nguva yekutumira: Mazuva 15-30 mushure mekusimbiswa kweodha (zvinoenderana nehuwandu, zvirevo uye kwaunoda kuenda).
7. Zvinokwanisika here kugadzirisa saizi?
Ehe, dhayamita, ukobvu hwemadziro zvinogona kugadziriswa zvichienderana nezvinodiwa nevatengi.
