Mapepala achitsulo ooneka ngati Z, chinthu chogwira ntchito kwambiri komanso chogwiritsidwa ntchito kwambiri, chimatchedwa chifukwa chofanana ndi chilembo "Z" m'gawo lawo. Milu yachitsulo yamtundu wa U (Larsen) Mitundu iwiriyi pamodzi imapanga maziko a uinjiniya wamakono wa milu yachitsulo yokhala ndi mawonekedwe osiyana kwambiri pakugwira ntchito ndi malo ogwiritsira ntchito.
Ubwino:
Chiŵerengero chachikulu cha modulus-to-weight ratio kuti chigwire bwino ntchito
Kulimba kwambiri kumachepetsa kupotoka
Kapangidwe kake konse kamalola kuyika kosavuta
Kukana dzimbiri kwambiri, ndi makulidwe owonjezera pazovuta kwambiri
Mulu wa Chitsulo Chopangidwa ndi U-Shaped Au Pu 6m-18m ndi njira yolimba komanso yolimba yopangira zipilala zachitsulo yopangidwira makoma osungira, nyumba za m'mphepete mwa nyanja, komanso ntchito zosungira nthaka.
Mulu wa pepala lachitsuloIli ndi ntchito zosiyanasiyana ndipo ingagwiritsidwe ntchito m'njira zosiyanasiyana zomangira. Ili ndi kuthekera kosinthasintha bwino m'nthaka ndi m'madzi, ndipo ingagwiritsidwe ntchito pa ntchito zomanga, malo osungiramo sitima ndi malo oimikapo sitima komwe zonse ziwiri zingakhalepo, ndipo ingagwiritsidwenso ntchito kuthandizira maenje akuya a maziko ndi matanki osungira zitsulo.
Kuthandiza kwamilu ya mapepala achitsuloKumaonekera mu kapangidwe katsopano ka zinthu zambiri zatsopano, monga nyumba zapadera zolumikizira zitsulo; Chowongolera cha hydraulic vibration pile chopangira mbale yachitsulo; Chotsekereza chosakaniza ndi utoto wa fakitale. Zinthu zingapo zimatsimikizira kuti sheet mulu ukadali chimodzi mwazinthu zothandiza kwambiri popanga: sikuti zimangothandiza kupititsa patsogolo ubwino wa chitsulo, komanso zimathandiza kufufuza ndi kupanga msika wa sheet mulu; Zimathandiza kukonza kapangidwe ka zinthu ndikukwaniritsa zosowa za ogwiritsa ntchito.
Mapepala achitsulo ndi zigawo zazitali zokhala ndi maulumikizidwe olumikizana, zomwe zimagwiritsidwa ntchito kwambiri ngati makoma osungira m'nyumba zam'mphepete mwa nyanja, ma cofferdams, ndi ntchito zina zosungira nthaka kapena madzi. Zopangidwa ndi chitsulo kuti zikhale zolimba komanso zolimba, kapangidwe kake kolumikizana kamathandiza makoma opitilira, kupereka chithandizo chabwino pakufukula ndi ntchito zomanga.
Mapepala achitsulo opangidwa ndi mawonekedwe a U oundana omwe ali mu chitsulo cha S235, S275, kapena S355, kutalika kwa mamita 6–18, abwino kwambiri posungira makoma, ma cofferdams, ndi maziko.
IziMapepala a Chitsulo Okhala ndi mawonekedwe a UZimakhala zozizira zopangidwa kutengera muyezo wa GB ndipo zitha kuperekedwa mu magiredi amphamvu kwambiri a Q235b, Q345b, Q390 ndi Q420. Zimagwiritsidwa ntchito poteteza makoma, maziko, ma cofferdams ndi ntchito zina zambiri zaukadaulo ndipo zimaperekedwa kutalika kuyambira 6m mpaka 18m. Kapangidwe ka Cold Formed U Pile kamapereka makulidwe ogwirizana komanso njira yolumikizirana, kulimba kwambiri mu nthaka ndi m'madzi.
Mtundu wa U 2kuyika mapepala achitsulondi chinthu chomwe chimagwiritsidwa ntchito kwambiri posungira nthaka ndikuthandizira kufukula. Chimapangidwa ndi chitsulo champhamvu kwambiri ndipo chili ndi gawo lozungulira looneka ngati U, zomwe zimapangitsa kuti kapangidwe kake kakhale kolimba komanso kolimba. Mapepala a U Type 2 amapangidwira kuti azilumikizana, ndikupanga khoma lopitilira ntchito zosiyanasiyana zomangira monga nyumba zam'mphepete mwa nyanja, ma cofferdams, ndi makoma osungira. Kusinthasintha ndi mphamvu ya mapepala achitsulo a U Type 2 zimapangitsa kuti ikhale chisankho chodziwika bwino pamapulojekiti aukadaulo omwe amafuna mayankho ogwira mtima komanso odalirika osungira nthaka.
Mulu wa pepala lachitsulo lolembedwa ndi Zndi gawo la zomangamanga lomwe limagwira ntchito bwino lomwe limagwiritsidwa ntchito kwambiri mu uinjiniya wa zomangamanga ndi zomangamanga.Mulu wa pepala lachitsulo looneka ngati Zndipo malo ake olumikizirana amapereka kukana kwabwino kwa katundu wa mbali, kukhazikika komanso kulimba, chifukwa chake amagwiritsidwa ntchito pophunzitsa kumanga makoma, m'mphepete mwa madzi, m'madoko, komanso m'mabwinja akuya kwambiri.
Mulu wa chitsulo wopangidwa ndi mawonekedwe a U wozizira wapangidwa kuti ugwirizane ndi zosowa za zomangamanga komanso zomangamanga. Uli ndi mphamvu zambiri ndipo umapezeka mu magiredi a SY295, SY390 ndi SY490. Milu iyi imapangidwa motsatira miyezo ya ASTM A328 ndi JIS A5528 zomwe zimapangitsa kuti miluyo ikhale yabwino kwambiri.
Milu ya mapepala achitsulo ya U ndi magawo opindika kapena olumikizidwa omwe amapanga khoma lofanana, lomwe nthawi zambiri limagwiritsidwa ntchito posungira nthaka kapena madzi. Mphamvu ya mulu wa mapepala imadalira mawonekedwe a mbiri ndi mawonekedwe a nthaka ndipo imagwira ntchito yosuntha mphamvu yomwe ili mbali yakumwamba ya khoma kupita ku nthaka yapafupi.
