Ubwino wa kuzizira kwa ozizira

Pomanga ndi magawo opanga, kusankha kwa zinthu zoweta ndi njira zomwe zimathandiza kuti ntchito iliyonse ithe. Chimodzi mwazinthu zotere zomwe zakhala zotchuka m'zaka zaposachedwa ndi chitoliro chozizira kwambiri. Chochita chatsopanochi chimapereka zabwino zambiri pa ziphuphu zosawoneka bwino kapena zazitali, makamaka mapaipi ozungulira.

 Kuzizira adapangidwaChitoliro chimapangidwa kudzera mu njira yopanga kuzizira, zomwe zimaphatikizapo kugwada ndikupanga zokongoletsera za chitsulo cholongosoka. Zotsatira zake ndi chitoliro chomwe chili cholimba komanso cholimba, koma chopepuka komanso chosavuta kugwiritsa ntchito. Kuphatikiza apo, njira yozizira yozizira imatsimikizira kuti chitolirocho chimasunga umphumphu ndi kulondola kwakukulu, kupangitsa kuti zikhale bwino pakugwiritsa ntchito.

Katundu wamakina

Kuphatikizika kwa mankhwala

Mayeso a Hydrostatic

Kutalika kwa chitoliro chilichonse chidzayesedwa ndi wopanga mphamvu zomwe zimapanga pakhoma la papaitoni zosakwana 60% ya ocheperako pa kutentha kwa firiji. Kupanikizika kudzatsimikizika ndi equation iyi:
P = 2st / d

Mitundu yovomerezeka yolemera ndi miyeso

Kutalika kwa chitoliro chilichonse chidzalemedwa mosiyana ndi kulemera kwake sikusintha kuposa 10% kapena 5.5% pansi pa kulemera kwake, kuwerengetsa kutalika kwake ndi kulemera kwake kutalika.
Kunja sikusiya kusiyanasiyana kuposa ± 1% kuchokera ku mainchesi omwe ali kunja.
Makulidwe a khoma nthawi iliyonse sadzapitilira 12,5% pansi pa khoma lotchulidwa.

Utali

Kutalika Kwachimodzimodzi: 16 mpaka 25ft (4.88 mpaka 7.62m)
Kutalika kawiri kawiri: kupitirira 25ft mpaka 3ft (7.62 ku 10,67m)
Kutalika kwa yunifolomu: Veriation yovomerezeka ± 1in

Mathero

Zitoma zitoma zidzaperekedwa ndi mathanthwe, ndipo zowotcha kumapeto zidzachotsedwa
Pamene chitoliro chikasokonekera kukhala bevel chimatha, ngodya lidzakhala 30 mpaka 35 digiri

Imodzi mwa zabwino zazikulu zopangidwa ndi zozizirachitoliro cha kuwotchererandi kuthekera kwake kupirira kutentha kwambiri ndi zovuta zambiri. Mosiyana ndi mapaipi achikhalidwe, omwe amatengeka ndi kutukuka ndi mitundu ina ya kuwonongeka, mapaipi okhala ndi ozizira amapangidwa kuti apirire ziwonetserozo za kuwotcherera ndi njira zina zamafakitale. Izi zimawapangitsa kukhala abwino kugwiritsa ntchito pamapulogalamu osiyanasiyana kuchokera ku zomangamanga kwa zomangamanga.

Ubwino wina wa chitoliro chozizira kwambiri ndi mphamvu yake. Njira yozizira yozizira imatha kubereka mapaipi osiyanasiyana komanso mawonekedwe, kuchepetsa kufunika kwa njira zoponyera ndi njira zoponyera. Izi zimapangitsa malonda kukhala otsika mtengo komanso odalirika ngati chitoliro chopanda nsapato kapena chowala. Kuphatikiza apo, chitoliro chopepuka cha chitoliro chozizira chimapanga mayendedwe ndikukhazikitsa mosavuta komanso okwera mtengo kwambiri, kukulitsa chidwi chake.

Sporsil Sammam Tubas amapindula ndi njira yozizira. Mphamvu yopanda mphamvu komanso kusinthasintha machubu ozizira kumawapangitsa kukhala abwino kuti apangire mafupa owoneka bwino. Izi zimawapangitsa kusankha bwino ntchito monga zotayira m'matumbo, mizere yamadzi ngakhale machitidwe othirira. Kuphatikiza apo, mawonekedwe osalala a mapaipi ozizira ozizira amachepetsa chiopsezo cha mkangano ndi kuvala, moyo wokulitsa womwe ukuchepetsa kufunika kokonza ndikukonzanso.

Ponseponse, chitumbuwa chozizira chopangidwa chimapereka zabwino zambiri zomwe zimapangitsa kuti kukhala ndi chisankho chabwino kwambiri polemba ntchito, makamaka chitoliro cha msipu. Mphamvu zawo, kulimba komanso kuchita bwino kumapangitsa kuti akhale ndi chisankho chowoneka bwino kwa mafakitale ambiri, kuchokera pantchito yopanga. Pofuna zinthu zapamwamba kwambiri, zodalirika zimapitilirabe, chitoliro chopangidwa ndi zinthu chozizira chimakhala chosagwiritsidwa ntchito chodziwika bwino pakugwiritsa ntchito.
