Mlatho prestressed pulasitiki malata kupanga mzere kupanga mzere ndi grouting chitoliro kupanga mzere amatumizidwa kwa makasitomala ku Chengdu,
Qingdao Cuishi pulasitiki makina kupanga pulasitiki mvuvu pulasitiki pe msewu waukulu pulasitiki chitoliro Bridge prestressed pulasitiki mvuvu kudzera zitsulo stranded konkire ndi nyumba mlatho prestressed pulasitiki mvuto
Izi makamaka ntchito kwa tapala, chitetezo otsetsereka, mkulu-liwiro mlatho prestress mavuto pulasitiki mvuto, prestressed malata mlatho chitoliro, mu kuthira nthawi kuteteza chingwe zitsulo ku kuipitsa, kuonetsetsa mikangano.Wopanikizika pulasitiki mvukuto mfundo zazikulu: 50 55 60 65 70 75 80 85 90 95 100 105 110 115 120mm khoma makulidwe 2.2-3cm
Mivuto ya pulasitiki yopanikizidwa ndi mvuvu yokhala ndi khoma limodzi yomwe imatulutsidwa ndi pulasitiki yotuluka ndi polyethylene yapamwamba kwambiri (HDPE) yopangira konkire yokhazikika ngati chitoliro chokhala ndi nthiti zokhazikika.Ndi njira yabwino yopangira zitsulo zoyambira mumlatho ndi zomangamanga.Mivuto ya pulasitiki imagawidwa m'magulu awiri: mapaipi ozungulira ndi mapaipi athyathyathya, omwe amagwirizanitsidwa ndi ntchito yeniyeni ndi mitundu yosiyanasiyana ya zolumikizira pulasitiki.Zopangira zopangira ma vuvu apulasitiki osindikizidwa ndi HDPE.Kukaniza kwake kwa dzimbiri ndikwabwino kwambiri kuposa zitsulo, osawopa dzimbiri la asidi ndi alkali, sizidziwononga zokha, ndipo zimatha kuteteza nthiti zokhazikika ku dzimbiri.

Pulasitiki mvuvu ngati prestressed pambuyo tensioning njira porous zinthu ndi mbali yofunika ya dongosolo prestressed, kwa nthawi yaitali prestressed zomangamanga ntchito zitsulo mvukuto ngati pore zakuthupi, pofuna kuthana ndi zophophonya zitsulo mvukuto kusindikiza osauka, kuwonongeka mosavuta, zosavuta dzimbiri, kukana kwakukulu kwamphamvu, komanso kuti mupereke chotchinga chowonjezera choletsa dzimbiri cha nthiti zokhazikika, tikulimbikitsidwa kugwiritsa ntchito polyethylene kapena polypropylene yopangidwa ndi mavuvu apulasitiki ngati chinthu chosinthira chokhala ndi njira yolumikizirana pambuyo polimbikitsa moyo. za kapangidwe
