Mawu Oyamba
France idatulutsa NFA-35-035 "Hot-dip galvanized and zinc aluminium alloy prestressed steel waya ndi zitsulo zomangika". Muyezo umakwirira awiri mwadzina wa 5.0mm, 6.0mm, 7.0 mm ndi kuyimitsidwa mlatho motero. Zizindikiro zazikulu zaukadaulo za waya wachitsulo / zinki zotayidwa ndi aluminiyamu zikuwonetsedwa patebulo.
Kapangidwe
Amakhala ndi mbale zonyamula katundu, ma wedge ndi ma wedge. Ikani tendon mu nangula ndikuyendetsa mphero mu mbale kuti mutseke tendon m'malo mwake. Nangula wa kupsinjika kwa ndege amapezeka m'makonzedwe osiyanasiyana, monga anangula amtundu umodzi wachitsulo chimodzi chachitsulo ndi anangula amitundu yambiri kwa mipiringidzo yambiri. Iwo ndi ofunikira kuti awonetsetse kusamutsidwa koyenera kwa prestress ku konkire, kupereka kukhulupirika kwapangidwe kofunikira pakugwiritsa ntchito.

Mawonekedwe
Waya wachitsulo amagawidwa mu Gulu A ndi B. Waya wachitsulo wa Gulu A amagwiritsidwa ntchito makamaka pazinthu zokhazikika zomwe zimakhala ndi chitetezo chaching'ono komanso katundu wochepa wamoyo. Kutopa kwake kumafuna malire a 0.70σb ndi 200 MPa.ndi 2 miliyoni kuzungulira. Waya wachitsulo wa Gulu B amagwiritsidwa ntchito makamaka pazingwe za mlatho wokhala ndi chitetezo chachikulu komanso katundu wamkulu wamoyo. Kukana kutopa kwake kumafuna 0.45σb yokhala ndi kupsinjika kwa 300 MPa ndi kuzungulira kwa 2 miliyoni. Nthawi yomweyo, muyezo umanenanso kuchuluka kwa waya wopindika mobwerezabwereza kuyesa mapulasitiki a waya.
Zopindulitsa
Chingwe cha Bridge ndiye njira yopulumutsira mlatho woyimitsidwa wautali wautali kapena mlatho wokhala ndi chingwe kudutsa nyanja ndi mtsinje. Kukana kwa dzimbiri kwa waya wake wachitsulo ndikofunikira kwambiri pakukhazikika komanso chitetezo cha kapangidwe kake. Muyeso umagawaniza magwiridwe antchito a waya wachitsulo m'magulu anayi:
(1) khalidwe ❖ kuyanika pa unit dera waya zitsulo;
(2) mphamvu yolumikizira ya zokutira;
(3) kupitiriza kwa zokutira; ndi
(4) mbali zina. Muyezo umafunikira kuti mtundu wa zokutira pagawo lililonse la waya wachitsulo ukhale 180 ~ 350 g / m2, kuchuluka kwa zokutira kumawerengedwa molingana ndi 7.2 g/cm3, ndipo makulidwe a zokutira ayenera kukhala 26 ~ 49m ku. Kuyendera njira ya khalidwe la zitsulo waya ❖ kuyanika pa mita lalikulu adzakhala NF EN1460, ndipo kutalika kwa chitsanzo mayeso adzakhala osachepera 150 mm. The polyethylene Chophimba kukhala chingwe / kanamalatika kufanana waya chingwe amapangidwa ndi kupotoza mkulu mphamvu kanasonkhezereka waya waya. ndiyeno kupaka waya wopotoka ndi polyethylene yapamwamba kwambiri ndi njira yotentha yotulutsa. lt amagwiritsidwa ntchito kwambiri ngati chingwe cha mlatho wokhazikika, chingwe chomangirira, hanger ya orch bridge, suspender for suspension mlatho ndi chingwe cha struduer yapadera.
Chingwe cha kugwedera kwa mphepo-mvula
Chingwe chotsalira ndi chimodzi mwa zigawo zofunika kwambiri za milatho yokhala ndi chingwe ndipo zimakhala zosavuta kugwedezeka pamene kutalika kwake kumawonjezeka.Zingwezi zimapangidwira kuchepetsa kugwedezeka komwe kumachitika chifukwa cha mphepo.Izi zimawonjezera moyo wa ntchito ya mlatho ndikupereka chitetezo chowonjezera.
Chingwe chokhala ndi waya wapawiri helical
Mawaya awiri a helical omwe ali pamtunda wokhala ndi kutalika kwake komanso phula amalepheretsa mphepo yamkuntho yomwe imapangitsa kugwedezeka.Tekinolojeyi yakhala ikugwiritsidwa ntchito bwino pamapulojekiti amilatho, monga Edong Yangtze River Bridge, Shenzhen Bay Bridge, Indonesia Suramadu Bridge, Jinan Jianbang Bridge. ndi zina zotero.
Chingwe cholimba kwambiri champhamvu kwambiri
Pamaziko a chingwe chokhazikika, chingwe champhamvu kwambiri (champhamvu mpaka 1770MPa, 1860MPa ndi 1960Mpa) chawonjezedwa ndi moyo wautumiki kwa zaka 50 pansi pazikhalidwe zabwinobwino pogwiritsa ntchito zopangira zabwinoko, kukonza njira zopangira. ndi chingwe kapangidwe.
lt wakhala akugwiritsidwa ntchito pa Sutong Bridge, Hong Kong Stonecutters Bridge, Zhujiang Huangpu Bridge, Jiashao Bridge, HongKong-Zhuhai-Macau Bridge etc.
Chingwe chachitali kwambiri komanso chachikulu
Pomanga milatho yokhala ndi chingwe ndi kutalika kwake kotalika kuposa 100m, zofunikira kuti zikhazikike zizikhala zokulirapo komanso zazitali m'litali komanso magwiridwe antchito.Pakali pano, kampani yathu imatha kupanga chingwe chotalikirapo komanso chachikulu chokhala ndi kutalika kwa 800m ndi kukula kwakukulu kungathe kufika ku511p7.Ndife akatswiri opanga okha omwe amatha kupanga chingwe chotalika kuposa500m.
