Kushandiswa Kukuru

1. Mabhesi eMadziro: Nheyo dzemadziro epasi pevhu dzezvivakwa zvirefu, zvefekitori, zvekuchengetera zvinhu, zvemabhizinesi kana zvekugara. Nheyo dzemurwi dzakakodzera marudzi ese ezvivakwa.

2. Nheyo dzeBridge Pile: Nheyo dzinotakura mutoro dzemabhiriji emigwagwa mikuru, njanji nemabhiriji emumaguta. Nheyo dzerwizi rwenzimbe, lacustrine, uye mapombi egungwa.

3. Kuvakwa kweChiteshi: Nheyo dzinotakura mutoro dzezviteshi zvechiteshi, nzvimbo dzekutakura ngarava, uye mapuratifomu echiteshi. Michina mikuru uye michina yekutakura zvinhu zvechiteshi.

4. Mapurojekiti eUinjiniya hweMarine neMapurojekiti emagetsi emhepo eOffshore: Nheyo dzematurbine emhepo ari kunze kwenyika. Dhizaini yekutsigira mapuratifomu ari kunze kwenyika, mapaipi ari kunze kwenyika, madziro egungwa, nezvimwewo. Kudzivirira mafungu, kuramba mafungu uye kuramba ngura mugungwa.

5. Uinjiniya Hwezvivakwa Hwakawanda, Mapombi Akakura:Basa guru rekugadzira mainjiniya ekuvaka (rakadai semadhamu, zviteshi zvepasi pevhu, uye matunnel) rinoda nheyo dzakadzika dzichishandisa mirwi yakakura. Rutsigiro rwemitoro yemaindasitiri, yemichina neyezvivakwa.

Kubatsira kweRoyal Steel Group (Nei Royal Group Ichinyanya Kukosha Kuvatengi vekuAmerica?)

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

Kurongedza Uye Kutumira

1. Kurongedza:Matambiro esimbi kuti zvive nyore kubata. Mabhuroko emapuranga kana dunnage zvinoiswa pakati pemaburi kuti zvisakuvadzwe panguva yekutakura. Kugadzirisa pamusoro (sarudzo): Pendi nhema, mafuta engura, purasitiki yakaputirwa. Mapombi egirazi anopisa anogonawo kuvharwa nefirimu rekudzivirira pamusoro kwenguva pfupi. Tinogonawo kupa mapurasitiki akagadzirirwa isu.

2. Kutumirwa:Kureba kwestoke kwakajairika: 6m, 12m. Kureba kwakagadzirirwa basa rako. Yakakodzera kutakurwa mugungwa, njanji nemumugwagwa. Nguva yekutanga yekugadzira inowanzo kuve mazuva 15-30 mushure mekubhadhara, kutumirwa nekukurumidza zvichienderana nehuwandu uye zvakatsanangurwa. Yakakodzera kutumirwa kunze kwenyika pasi rese nemagwaro akazara (chitupa chekuongorora, runyorwa rwekurongedza, bhiri rekutakura zvinhu).

Matanho ekudzivirira:

1. Crane kana forklift ine slings kana slingshoes inofanira kushandiswa kudzivirira kuchinja kwepombi muHanding Peoperties.

2. Chengetai nzvimbo inotonhorera, yakaoma uye ine mhepo inofema kuti muchengete, kana kuti ngura ingavepo musati maisa. Kana mabhegi makuru/akarema zvakanyanya, ndapota teverai mutemo wekutumira wemuno zvakanyanya.

Mibvunzo Inowanzo bvunzwa

1. Chii chinonzi ASTM A252 Grade 3 steel piles?
Mapombi esimbi eASTM A252 egiredhi rechitatumapaipi esimbi akasungirirwa esimbi anoshandiswa sekutsigira hwaro hwakadzika pasi pezvivakwa, mabhiriji, madoko, uye mainjiniya ekunze kwenyika. Kune maitiro maviri ekushongedza mapaipi aya: mapaipi ekushongedza arc akasungirirwa ehelical (SSAW) kana mapaipi ekushongedza arc akasungirirwa elongitudinal (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.
