Mu dziko la zomangamanga za zomangamanga lomwe lili ndi mavuto ambiri, mlatho umakhala wolimba ngati mgwirizano wake wofooka kwambiri—ndipo nthawi zambiri, mgwirizano wofookawo ndi womwe ukukula. Pamene mapulojekiti a zomangamanga ku North America, Europe, ndi Middle East akukumana ndi miyezo yolimba kwambiri (monga AASHTO ku US ndi Eurocodes ku EU), kufunikira kwa njira zabwino zotsekera sikunakhalepo kovuta kwambiri.

Zinthu Zovuta Kwambiri Pakumanga ndi Kukonza Mlatho

• Kulowa m'madzi ndi dzimbiri: Mdani woyamba pa moyo wautali wa mlatho ndi madzi omwe amatuluka kudzera m'malo olumikizirana, ma bearing achitsulo omwe amawononga, kuzizira m'ming'alu (kuzizira ndi kusungunuka), komanso nyumba zomangira za konkriti zomwe zimawonongeka. Zisindikizo zokhazikika nthawi zambiri zimalephera kupanga loko yolimba motsutsana ndi kuthamanga kwa madzi mwamphamvu.
• Kusuntha Kosinthasintha & Kutopa: Milatho imakula ndikuchepa nthawi zonse chifukwa cha kusintha kwa kutentha ndi kuchuluka kwa magalimoto. Mphete zomangira zodziwika bwino zimataya kulimba pakapita nthawi, zomwe zimapangitsa kuti pakhale mipata, kung'ambika, komanso kulephera kwa dongosolo.
• Kukhazikitsa Movuta M'malo Ovuta: Kuyika ma gasket otsekera m'mizere ya konkire yomwe yapangidwa kale kungakhale kovuta. Ma tepi osalala nthawi zambiri amatsetsereka kapena kulephera kukhazikika bwino panthawi yothira kapena kukonzanso, zomwe zimapangitsa kuti zichedwe.
• Kuwonongeka kwa Mankhwala ndi UV: Kukhudzidwa ndi mchere wa m'misewu, mankhwala ochotsa icing, ozone, ndi kuwala kwamphamvu kwa UV kumawononga mwachangu mankhwala osafunikira a mphira, zomwe zimapangitsa kuti ming'alu ndi kuuma.
• Zoopsa Zokhudza Kutsatira Malamulo: Kulephera kukwaniritsa miyezo yokhwima ya Dipatimenti Yoona za Mayendedwe (DOT) kapena European Norm (EN) yokhudza kulimba kwa madzi ndi kuyenda kungayambitse kukanidwa kwa kuwunika ndi kukonzanso kokwera mtengo.

Chifukwa Chake Makampani Apamwamba Opanga Ma Bridge Amatchula Annilte

Ubwino wa Annilte: Mphamvu ya Kapangidwe ka Mano Odula

1. Kulumikizana Kwapamwamba Kwambiri kwa Makina: Mbiri ya mano atatu odulidwa imapanga mgwirizano wamphamvu wamakina ndi konkire kapena mlatho wa matope. Mosiyana ndi matepi osalala omwe amadalira kokha kumamatira, mawonekedwe athu "amaluma" muzinthu zokonzera, zomwe zimaletsa kutsetsereka panthawi yoyika ndi nthawi yogwirira ntchito.
2. Chotchinga Madzi Cholowera Mbali Zambiri: Kuzungulira kwa mano odulidwa kumapanga njira yodutsa madzi. Ngakhale pansi pa mphamvu ya hydrostatic, madzi ayenera kuyenda mmwamba mopingasa kuti alowe m'malo olumikizirana, zomwe zimachepetsa kwambiri chiopsezo cha kutuluka kwa madzi poyerekeza ndi zisindikizo zathyathyathya.
3. Kusinthasintha Kowonjezereka ndi Malo Oyendetsera: Yopangidwa kuchokera ku EPDM yapamwamba kapena Neoprene compounds, "mano" osinthasintha amakanikiza ndikukula mosavuta, kulola mayendedwe ofunikira akutali, opingasa, komanso oimirira popanda kutaya umphumphu wa chisindikizo.
4. Kukana Kwambiri Zachilengedwe: Matepi athu amalimbana ndi kutentha kuyambira -40°C mpaka +80°C, ndipo amalimbana ndi ozone, kuwala kwa UV, ndi mchere wochotsa icing, zomwe zimapangitsa kuti ntchito yawo ikhale ya zaka zoposa 50 m'nyengo yozizira.
5. Mapangidwe a Mphete ndi Matepi Osinthika: Kaya mukufuna ma roll osalekeza a viaducts ataliatali kapena ma Sealing Rings opangidwa kale kuti mulumikizane ndi mipiringidzo yovuta kapena milu, Annilte amapereka njira zopangidwira bwino zomwe zimagwirizana ndi mapangidwe enaake a ma connection.

Kugwira Ntchito Kotsimikizika mu Mapulojekiti Akuluakulu Omanga Nyumba

"Pa kukonzanso kwathu kwaposachedwa kwa mlatho wopachikidwa, liwiro loyika ndi kudalirika kwa tepi yotsekera mano ya Annilte ya triangle saw-tooth zinali zapadera kwambiri. Kugwira kwa makina kunathetsa mavuto omwe tinkakumana nawo ndi ogulitsa akale, ndipo mayeso oletsa madzi adapitilira zofunikira za DOT ndi 20%.—Mainjiniya Wamkulu wa Zachilengedwe, Wopanga Zomangamanga Wamkulu, USA
