Kodi Pali Kusiyana Kotani Pakati pa Milu Yachitsulo Yoyingidwa Yotentha Ndi Milu Yachitsulo Yoyingidwa Yozizira?

Pankhani ya zomangamanga ndi zomangamanga,Milu ya Zitsulo(nthawi zambiri amatchedwakupaka mapepala) Kwa nthawi yaitali akhala mwala wapangodya wa mapulojekiti omwe amafunikira kusungidwa kwa nthaka modalirika, madzi osasunthika, ndi chithandizo cha zomangamanga - kuyambira kulimbitsa magombe a mitsinje ndi chitetezo cha m'mphepete mwa nyanja mpaka kukumba pansi ndi zotchinga zomanga kwakanthawi. Komabe, si Milu ya Zitsulo zonse zomwe zimapangidwa mofanana: njira ziwiri zoyambirira zopangira-kugudubuza kutentha ndi kuzizira-zimapanga zinthu zosiyana, Milu Yachitsulo Yotentha Yotentha ndi Cold Formed Rolled Steel Sheet Piles, iliyonse ili ndi makhalidwe apadera omwe amawapangitsa kukhala oyenerera ntchito zina. Kumvetsetsa kusiyana kwawo ndikofunikira kwa mainjiniya, makontrakitala, ndi oyang'anira polojekiti kuti apange zisankho zotsika mtengo, zoyendetsedwa ndi magwiridwe antchito.

Njira zopangira mitundu iwiri yowunjika mapepala zimakhazikitsa maziko azinthu zawo zosiyanasiyana.Milu ya Zitsulo Zotentha Zotenthaamapangidwa ndi zitsulo zotentha zotentha kutentha kwambiri (nthawi zambiri pamwamba pa 1,000 ° C) mpaka chitsulocho chimakhala chosinthika, kenako ndikuchidutsa muzodzigudubuza kuti chizipangitse kuti zikhale zolumikizana (monga mtundu wa U, mtundu wa Z, kapena ukonde wowongoka) womwe umatanthawuza kuyika mapepala. Kutentha kwapamwamba kumeneku kumapangitsa kuti pakhale zovuta, zolimba zopingasa komanso zimatsimikizira kuti zinthu zofanana zimakhala zofanana, chifukwa kutentha kumathetsa mavuto amkati muzitsulo. Motsutsana,Milu Ya Zitsulo Zozizira Zopangidwa Ndi Zitsuloamapangidwa kuchokera kuzitsulo zachitsulo zomwe zimadulidwa kale, zomwe zimapangidwira kuti zikhale zolumikizana pogwiritsa ntchito zodzigudubuza ozizira-palibe kutentha kwakukulu komwe kumagwiritsidwa ntchito popanga. Kuzizira kozizira kumadalira kusinthasintha kwachitsulo kutentha kwa chipinda, ndikupangitsa kuti ikhale yabwino popanga mbiri yopepuka, yokhazikika, ngakhale ikhoza kuyambitsa zovuta zazing'ono zamkati zomwe zimafuna kukonzanso pambuyo (monga annealing) pazinthu zina zolemetsa kwambiri.

Magwiridwe ndi structural makhalidwe a mitundu iwiri ya zitsulo mapepala milu

Mawonekedwe a machitidwe ndi mapangidwe amasiyanitsanso mitundu iwiriyi. Milu ya mapepala otenthedwa ndi otentha imapereka mphamvu ndi kukhalitsa kwapadera: mawonekedwe awo otenthedwa ndi otentha amapereka mphamvu zowonjezereka, zokolola, ndi kukana kukhudzidwa, zomwe zimawapangitsa kukhala abwino kwa ntchito zolemetsa, za nthawi yaitali. Mwachitsanzo, milu ya mapepala otenthedwa ndi otentha nthawi zambiri imakonda kukumba mozama (pomwe milu ya mapepala iyenera kupirira kupanikizika kwakukulu kwa nthaka) kapena chitetezo cham'mphepete mwa nyanja (chomwe chimakhala ndi nyengo yovuta komanso dzimbiri lamadzi a m'nyanja). Mukagwiritsidwa ntchito ndi zokutira (monga epoxy kapena zinki), milu ya pepala yotentha yotentha imaperekanso kukana kwa dzimbiri, chifukwa mawonekedwe a yunifolomu amatsimikizira kumatira kofanana kwa gawo loteteza. Komano, milu ya mapepala ozizirirapo imakhala yopepuka komanso yotsika mtengo pakugwiritsa ntchito kwakanthawi kapena kwapakatikati. Kutsika kwawo kumapangitsa mayendedwe ndi kukhazikitsa mosavuta - kumafuna zida zochepa ndi ntchito - kuwapangitsa kukhala abwino pantchito yomanga kwakanthawi kochepa, kusefukira kwamadzi kwakanthawi, kapena ntchito zapansi pazipinda zapansi, pomwe kunyamula katundu kwambiri sikofunikira kwenikweni. Ngakhale kuti mphamvu zawo ndizochepa kusiyana ndi njira zawo zotentha zotentha, kupita patsogolo kwaposachedwa kwaukadaulo wopangira kuzizira (monga ma alloys achitsulo champhamvu kwambiri) kwawonjezera ntchito yawo m'mapangidwe osakhalitsa.

Mtengo ndi kupezeka kwa mitundu iwiri ya milu yachitsulo yachitsulo

Mtengo ndi kupezeka ndizofunikanso kwambiri posankha pakati pa ziwirizi. Cold Formed Rolled Steel Sheet Milu nthawi zambiri imakhala yotsika mtengo wakutsogolo, chifukwa kugudubuzika kozizira kumakhala kopanda mphamvu, kumafuna zida zochepa zapadera, ndipo kumatulutsa zinyalala zochepa poyerekeza ndi kugudubuza kotentha. Amapezekanso mosavuta mumiyeso yokhazikika, yokhala ndi nthawi yocheperako yopangira - yofunika kwambiri pama projekiti okhala ndi ndandanda yolimba. Milu Yachitsulo Yotentha Yotentha, mosiyana, imakhala ndi ndalama zambiri zopangira chifukwa cha kutentha kwamphamvu kwambiri komanso kufunikira kwa makina ovuta kwambiri. Mbiri zamakasitomala (zopangidwira zosowa zapadera za polojekiti) zimawonjezeranso mtengo wawo komanso nthawi yotsogolera. Komabe, kukhazikika kwawo kwanthawi yayitali nthawi zambiri kumathetsa ndalama zoyambira: m'malo okhazikika, Milu ya Zitsulo Zotentha Zotentha zimafuna kusamalidwa pang'ono komanso kukhala ndi moyo wautali wautumiki, kuchepetsa mtengo wamoyo pakapita nthawi.

Ubwino wawo

Mwachidule, milu yonse yotentha yotentha komanso yozizira imakhala ndi gawo lofunika kwambiri pakumanga kwamakono, koma kusiyana kwawo pakupanga, ntchito, ndi mtengo wake kumawapangitsa kukhala oyenera kugwiritsa ntchito zenizeni. Milu ya mapepala otenthedwa ndi otentha amadziwika chifukwa cha mphamvu zawo, kulimba, komanso kuyenerera kwa ntchito zokhazikika, zolemetsa, pamene milu ya mapepala oundana ozizira amapereka zotsika mtengo, zosavuta kuziyika, ndi kusinthasintha, kuzipanga kukhala zoyenera ntchito zosakhalitsa kapena zapakatikati. Pamene kufunikira kwa zomangamanga zokhazikika komanso zogwira mtima kukukulirakulirabe, akatswiri amakampani amalosera kuti kupitilirabe zatsopano m'njira zonse ziwiri, kuchokera kuzitsulo zoziziritsa kuzizira zokhala ndi mphamvu zambiri mpaka ukadaulo wogwiritsa ntchito mphamvu zotentha zotentha, kukulitsa kusinthasintha kwa milu ya mapepala ndi mayankho amilu yamasamba padziko lonse lapansi.
