Kusintha kwa mphira

zolemba zogwiritsira ntchito

1. pansi pa njanji zowala, zomwe zimapangitsa kuti zigwedezeke ndikuwombera chifukwa cha masitima a sitima

2. mu njanji yowuma ndi njira zapamsewu, zimachepetsa phokoso lantchito ndi kugwedezeka

3. pa trady-bridge lopts, kusokoneza mphamvu

4. tsatirani malo osungirako zinthu, onjezerani kukhazikika ndi kukhazikika

mafotokozedwe akatundu

mitundu ya mphira iyi ndi yopangidwa ndi zochitika zosiyanasiyana zaukadaulo, kupereka zosankha ziwiri zakuthupi: rabara wachilengedwe (nr) ndi chloroprene rabara (kr). zogulitsa zimakhala ndi mphamvu yayikulu ya> 15mmka ndi magwiridwe abwino kwambiri amphamvu (amphamvu-stifken stifnenal rafio <1.5). pambuyo pa kutopa kwa miliyoni 3 miliyoni, kusintha kwaukali ndi <15% kusintha kwa makulidwe ndi <10%, kupereka chithandizo cha nthawi yayitali monga momwe zimakhalira ndi zida zapamwamba monga zida zapamwamba komanso zida zolemera.

ntchito yothandizira

kutsatsa kwamphamvu:

chiwerengero champhamvu kwambiri champhamvu chimayendetsedwa mosamalitsa pansipa 1.5, onetsetsani kuti kuyamwa kwamphamvu kwamphamvu pansi pa katundu wamphamvu.

pambuyo pa kutopa kwa 3 miliyoni, kulimba mtima kumakhalabe> 85%, kupewa kuwonongeka kwa magwiridwe antchito chifukwa chogwiritsa ntchito nthawi yayitali.

zochitika zinthu zosintha:

phunziro lachilengedwe (nr) mndandanda: zopangidwa ndi kutalika kwambiri komanso kutentha kochepa omanga, zoyenera kugwedezeka kokhazikika m’malo abwinobwino kutentha.

chloroprene rabara (cr) mndandanda: mafuta osemphana ndi nyengo, kutentha – kutentha / kutentha kwa mankhwala.

chitsimikizo cha zida zankhondo:

ndi tunsile mphamvu> 15mm ndi makulidwe amasintha <10% pambuyo pa kutopa, imasunganso umphumphu.

chithandizo cha kapangidwe kake:

pezani mayankho a zinthu komanso njira zobwezeretsera zokhazikitsidwa ndi chingwe, sing’anga ya chilengedwe, ndi malo okhazikitsa.

index

zolemba: mpira wachilengedwe (nr), chloroprene rabara (kr) ndi njira

mphamvu yamakina: kukhala mphamvu yamphamvu ≥1mpo

makhalidwe a harmic: okhazikika

moyo watcht: kusintha kwa smiffness ≤15% ndi kuthira mazira ≤10% pambuyo pa miliyoni 3 miliyoni

kusintha kwa chilengedwe: nr zigawo (-40 ℃ ~ 70 ℃); mitengo (-30 ℃ ~ 120 ℃)

malo ogwiritsira ntchito

sitima yapa njanji: mapiritsi a njanji, sinthanitsani mabatani, makina oyimitsidwa

zida zopangira mafakitale

upangiri wa ntchito: mavalidwe omanga a bridge, kumanga zigawo zikuluzikulu, ziphuphu zotsutsana ndi selimation

magetsi: jeneretor amakhazikitsa maziko odzipatula, payipi ya mafuta anti-seomic

makina olemera: port crane kugwedeza mapepala, zokhudzana ndi chifuwa cha chuma
