Ubwino ndi kuipa kwa konkire nthunzi kuchiritsa

Pakumanga uinjiniya, pali ulalo wofunikira, kugwiritsa ntchito ma jenereta a nthunzi pochiritsa konkriti yopangidwa ndi nthunzi.Jenereta ya konkriti ndiyoyenera kwambiri njanji yothamanga kwambiri, misewu yayikulu, yomanga mlatho, zida za konkriti, matabwa a bokosi, matabwa a T, matabwa opitilira, matabwa a U ndi matabwa oponyedwa m'malo, kuponyedwa m'malo kapena kukonza konkire. ntchito za docks ndi misewu.

Kutentha ankalamulira machiritso pambuyo precast konkire kuchiritsa phukusi

Pankhani yokhazikitsa ntchito yomanga, kuchiritsa kwa nthunzi kwadziwika pang'onopang'ono pomanga ntchito zazikulu.Pomanga mlatho wamakono, ma jenereta a nthunzi amagwiritsa ntchito nthunzi kutenthetsa konkire, zomwe zimapangitsa kuti konkire ikhale yolimba mofulumira pa kutentha kwakukulu (70 ~ 90 ° C) ndi chinyezi chapamwamba (pafupifupi 90% kapena kuposa).

Kuchiritsa nthunzi kumatha kuwongolera bwino matabwa a bokosi la konkriti, kufupikitsa nthawi yomanga, ndikuwonetsetsa kuti matabwa abokosi ali abwino.Jenereta ya Nobeth ndi yotetezeka, yosamalira zachilengedwe, yosavuta kugwiritsa ntchito, mafoni, komanso yodziwikiratu kuti ikwaniritse "osayang'aniridwa, kukonza zodziwikiratu" ”, opanga ma jenereta akuluakulu pamsika amawona kuchiritsa konkire ngati imodzi mwamisika yawo yomwe akufuna. pali milandu yambiri yogwiritsira ntchito okhwima.

Kukonza mlatho precast

Pogwiritsa ntchito filimu ya pulasitiki pochiritsa, mbali zowonekera za konkire ziyenera kuphimbidwa mwamphamvu ndi mapepala apulasitiki kuti zitsimikizire kuti pali madzi osungunuka mu mapepala apulasitiki kuti akwaniritse cholinga cha kuchiritsa konyowa.M'malo opanda madzi ndi nyumba zazitali zomwe zimakhala zovuta kuthirira ndi kusamalira, njira yothetsera thanzi la pulasitiki yopopera ingagwiritsidwe ntchito pokonza.Nthawi zambiri, 2 mpaka 4 maola konkire kutsanuliridwa, pamene madzi okhetsa magazi atangobalalika ndipo palibe madzi oyandama, mukhoza kupopera mankhwala ochepetsetsa a filimuyo pamene palibe zizindikiro zala pa konkire.Palibe amene amaloledwa kuyenda pa konkire mpaka mphamvu yake ifika 1.2MPa.Nthawi zambiri, kuchiritsa kwa nthunzi pa kutentha pafupifupi 65 ° C kumalimbikitsidwa.

Kaya kuchiritsa konkriti ndikwabwino kapena ayi?Nthawi zambiri, konkire imatha kufikira mphamvu yofunikira pamikhalidwe ya kutentha ndi chinyezi chambiri.Chifukwa cha kuchepa kwa malo omangapo, zida zomangidwa kale zimatha kugwiritsa ntchito maenje osakhalitsa kapena apansi panthaka, ophimbidwa ndi chivundikiro choteteza kapena chinsalu chosavuta kapena nsaru.Kukonza konkire ndi gawo lofunika kwambiri pa ntchito yomanga konkire ndipo kumagwirizana mwachindunji ndi khalidwe la zomangamanga la polojekiti yonse.
