chiyambi cha mankhwala
Bokosi lachitsulo lachitsulo, lomwe limatchedwanso steel box girder, ndi njira yomwe imagwiritsidwa ntchito popanga milatho yayitali. Kaŵirikaŵiri amagwiritsidwa ntchito pa milatho ikuluikulu, imatchedwa zitsulo zamabokosi zitsulo chifukwa zimawoneka ngati bokosi.Ikhoza kugawidwa m'mitundu itatu: mlatho umodzi wa girder bridge, double box girder bridge, ndi multiple box girder bridge.
M'milatho yayikulu yokhala ndi zingwe, chotchingira chachikulu cha bokosi lachitsulo chimatalika mazana angapo mita kapena masauzande a mita.
Imagawidwa m'magawo angapo a mtengo wopanga ndi kuyika, ndipo gawo lake la mtanda limakhala ndi mawonekedwe amtundu wamba ndi lathyathyathya, ndipo chiŵerengero chake chimafika pafupifupi 1:10. Chitsulo cha bokosi lachitsulo nthawi zambiri chimapangidwa ndikuwotcherera mbale yapamwamba, mbale yapansi, ukonde, ndi magawo odutsa, magawo aatali ndi zouma. Chipinda chapamwamba ndi chotengera cha orthotropic cha mlatho chomwe chimapangidwa ndi mbale yophimba ndi zolimba zotalikirapo. The makulidwe a mbale lililonse zitsulo bokosi girder akhoza kukhala: chivundikiro makulidwe 14mm, kotalika U woboola pakati nthiti makulidwe 6mm, chapamwamba m'kamwa m'lifupi 320mm, m'munsi m'kamwa m'lifupi 170mm, kutalika 260mm, katayanitsidwe 620mm; pansi mbale makulidwe 10mm, longitudinal U woboola pakati stiffeners; Makulidwe a ukonde wopendekera ndi 14mm, makulidwe a ukonde wapakati ndi 9mm; kutalika kwa magawo odutsa ndi 4.0m, ndipo makulidwe ake ndi 12mm; kutalika kwa mtengo ndi 2 ~ 3.5m.
Steel box girder ndi mawonekedwe omangika omwe amagwiritsidwa ntchito nthawi zambiri mu engineering. Kuti muphunzire kutengera kwa masinthidwe a ma diaphragms osinthika pakusokonekera kwa chomangira chachitsulo chothandizira pansi pa katundu wokhazikika, cholumikizira chosavuta chachitsulo chokhala ndi ma diaphragms osinthika adayikidwa kuti afananize zotsatira zake za Kupotoza ndi kukhazikika kokhazikika. pansi pa katundu, kusintha kosinthika kwa zotsatira zosokoneza kwambiri ndi chiwerengero cha diaphragms chimapezeka. Katundu wokhazikika umayikidwa pamwamba pa ukonde wa girder, ndipo umatengedwa molingana ndi mikhalidwe inayi yogwirira ntchito ya kupotoza, kugwedezeka kolimba, kupindika kofananira ndi katundu wa eccentric. Njira yowonongeka kwa katundu imawerengedwa.
Makampani a Zhenjiang Great Wall Heavy ali ndi matani opitilira 50 a cranes, mapangidwe aukadaulo, kuwotcherera, ndi magulu oyika amapanga ndikuyika matabwa osiyanasiyana azitsulo.
Ntchito zamalonda
Chifukwa cha mawonekedwe ake, chotchinga chachitsulo chimagwiritsidwa ntchito ngati chotchingira chachitsulo chokwera komanso chokwera; yomanga nthawi magalimoto gulu yaitali chingwe anakhala mlatho, kuyimitsidwa mlatho, Chipilala mlatho stiffening girder ndi oyenda mlatho zitsulo bokosi girder.
Ubwino wa mankhwala
1. Kuthamanga kwambiri kwamphamvu komanso kunyamula katundu wambiri
2. Kapangidwe ka kuwala, koyenera kwa milatho yayitali
3. Kuyika kosavuta, mtengo wotsika, mkombero waufupi
4. Ubwino wotsimikizika ndi kuchuluka kwake, komanso kudalirika kwakukulu
5. Kumanga kwakukulu ndi chitetezo chapamwamba
