"Steam Health" imathandiza kumanga konkire kumapangitsa kuti ntchito ikhale yabwino komanso yogwira mtima

Zima ndi nyengo yovuta kwambiri yomanga konkire.Ngati kutentha kuli otsika kwambiri, sikuti ntchito yomangayo idzachepetsedwa, koma hydration yachibadwa ya konkire idzakhudzidwanso, zomwe zidzachepetsa kukula kwa mphamvu za zigawozo, zomwe zimawopseza mwachindunji khalidwe la polojekiti ndi ntchito yomanga.Momwe mungagonjetsere vuto losasangalatsali lakhala vuto lalikulu lomwe likukumana ndi zomangamanga pakali pano.

Chifukwa cha ndandanda yolimba yomanga ndi ntchito zolemetsa, nyengo yozizira yatsala pang'ono kulowa.Potengera mawonekedwe a nyengo yakumaloko, pofuna kuwonetsetsa kuti ntchitoyo ikuyenda bwino, mayunitsi ena adalamula ma jenereta angapo a Nobis konkriti kuti asiye njira yochiritsira yothirira madzi ndikugwiritsa ntchito njira yochizira nthunzi kuti akwaniritse zowongolera. kuchiritsa konkriti.

Chifukwa chake ndi chosavuta.Ngakhale njira yachikhalidwe ndi yothandiza, kudalira kokha kusungirako kutentha kwa konkire ya hydration reaction pambuyo popaka sikungatsimikizire kutentha ndi kukhazikika.Mphamvu ya konkire imakula pang'onopang'ono ndipo ubwino wa polojekitiyi umakhala wovuta.Komabe, ndi koyenera kugwiritsa ntchito kayendedwe ka nthunzi kuti tisunge kutentha ndi kukhazikika kwa kutentha ndi chinyezi, komanso kugwiritsa ntchito mawonekedwe ake ofanana kuti akwaniritse kuwongolera koyenera.

Ukadaulo waumoyo wa Steam

Kuchuluka kwa ntchito: Pamene kutentha kwakunja kuli kwakukulu kuposa 5 ℃, koma chifukwa cha nthawi yayitali ya njira yachilengedwe yochiritsa yakuwaza madzi, kuti apititse patsogolo kuchuluka kwa magwiritsidwe ntchito azinthu zobweza monga nkhungu ndi zoyambira ndikuwongolera magwiridwe antchito, Njira yochizira nthunzi iyenera kugwiritsidwa ntchito kuti muchepetse mphamvu ya zinthu zosiyanasiyana zachilengedwe.

Kapangidwe ka mapaipi a nthunzi: Kumanga konkire kumachitika m'dzinja.Konkire yokha imataya chinyezi mwamsanga, makamaka masana.Ndikoyenera kutsanulira ndi kuphimba mu zigawo;ikani mapaipi a nthunzi omwe akonzedwa kale musanaphimbe, ndiyeno muwagoneke kumapeto kwa nthunzi yothiramo madzi ataphimbidwa.Yatsani nthunzi kuti muzisamalira thanzi.

【Nthawi yolima isanayambe】
Nthawi yabwinobwino, nthawi yochiritsa konkire ya konkriti ndi maola 2, yomwe ndi nthawi yoyambira kutsitsa konkriti mpaka kuyamba kwa nthunzi.M'dzinja, chifukwa konkireyo imataya madzi mofulumira, ola limodzi pambuyo pa nthawi yochiritsira isanayambe, jenereta ya nthunzi imagwiritsidwa ntchito kutumiza nthunzi ku malo opangira nthunzi katatu, nthawi iliyonse kwa mphindi 10.

【Kutentha kwanthawi zonse】
Nthawi yotentha yokhazikika ndiyo nthawi yayikulu ya kukula kwa konkriti.Nthawi zambiri, zigawo zikuluzikulu luso la nthawi zonse kutentha ndi: kutentha zonse (60 ℃ ~ 65 ℃) ndi zonse kutentha nthawi ya maola oposa 36.

【Chigawo chozizirira】Pa nthawi yozizira, chifukwa cha vaporization mofulumira madzi mkati mwa konkire, komanso shrinkage wa chigawo voliyumu ndi m`badwo wamakokedwe kupsyinjika, ngati kuzirala liwiro mofulumira kwambiri, mphamvu ya konkire idzachepetsedwa, ndi ngakhale ngozi zabwino zidzachitika;nthawi yomweyo, pa siteji iyi, ngati Kutaya madzi kwambiri kudzakhudza hydration kenako kukula mphamvu.Choncho, panthawi yozizira, kutentha kwa mpweya kuyenera kuyang'aniridwa mpaka ≤3 ° C / h, ndipo chokhetsa sichikhoza kukwezedwa mpaka kusiyana kwa kutentha pakati pa mkati ndi kunja kwa shedi ndi ≤5 ° C.Ma formwork amatha kuchotsedwa patatha maola 6 chokhetsedwa chikachotsedwa.

Zigawozo zitatsegulidwa ndikuchotsa mawonekedwewo, zidazo zimafunikirabe kupopera madzi kuti zisungidwe.Nthawi yokonza ndi ≥3 masiku ndi ≥4 pa tsiku.Kumanga kokonzedweratu m'nyengo yozizira sikungakhale kusasamala.Pambuyo kutsanuliridwa konkriti, njira yofunika kwambiri yokonza iyenera kuchitidwa kuti iwononge kutentha ndi chinyezi cha kunja kwa bokosi la bokosi kuti tipewe zoopsa zobisika zomwe zimayambitsidwa ndi kutentha kwambiri.

Masiku atatu oyamba atatha kuthira konkire ndi nthawi yovuta kwambiri yowonjezeretsa mphamvu za zigawozo.Njira zochiritsira zachikhalidwe nthawi zambiri zimatenga masiku 7 kuti zikwaniritse zofunikira zamphamvu.Tsopano njira yothetsera nthunzi imagwiritsidwa ntchito pochiritsa.Mphamvu imakula mofulumira kuposa kuchiritsa wamba ndipo kukula kumakhala kokhazikika.Zimatsimikizira kuti konkire ikufika ku mphamvu yochotsa formwork mwamsanga, imafupikitsa ndikusunga nthawi yomangamanga, imatsimikizira nthawi yomanga, ndipo imalola Kumanga kwa Bridge Bridge ya Jiasa ikufulumira kachiwiri.
