M’kati mwa nkhondo yachiŵiri ya padziko lonse, mlatho wazitsulo wa asilikali unagwiritsidwa ntchito kwambiri. Nkhondo itatha, mayiko ambiri anasintha mlatho wachitsulo wa Bailey pambuyo pa kusintha kwa ntchito za anthu wamba. Masiku ano, imasewera yofunika kwambiri

ntchito yomanga za mayendedwe ndi kulimbana ndi kusefukira kwa madzi.

Mlatho wachitsulo wa Baileyadatengera dongosolo lachitsulo lokhazikika, lotchedwa Bailey zitsulo mlatho wotsogola zitsulo, ndi anthu omwe ali muzitsulo zokhala ndi zitsulo mwachidziwitso adayambitsa kupsinjika kwa anthu kuti athetse kupsinjika kwa katundu, kusintha mphamvu yamkati, kupititsa patsogolo kuuma kwapangidwe ndi kukhazikika kwake, kusintha. kapangidwe kazinthu zina ndikugwiritsa ntchito ukadaulo wa prestress kupanga dongosolo latsopano. Mawonekedwe ake akuluakulu ndi awa:

1. Mokwanira ndi mobwerezabwereza amagwiritsira ntchito mphamvu zotanuka matalikidwe a zitsulo, motero kuwonjezera mphamvu yobereka ya kapangidwe kake.

2. Kupititsa patsogolo kupanikizika kwapangidwe ndikusunga chitsulo. Kuchokera pazimenezi, dongosolo la prestressed lingathenso kupulumutsa 30% yazitsulo.

3. Imawongolera kulimba kwapangidwe ndi kukhazikika, ndikuwongolera zinthu zosiyanasiyana za kapangidwe kake.

Kapangidwe kazitsulo kokhazikika kumatha kubweretsa phindu lalikulu lazachuma, kupulumutsa zitsulo zambiri, kuchepetsa mtengo wathunthu. Chuma ndi dongosolo structural dongosolo prestressed zitsulo, chiwembu mabasi ndi ndondomeko, katundu chilengedwe ndi mphamvu, structural dongosolo ndi mfundo, njira unsembe ndi mtengo zinthu ndi zina zambiri zokhudzana.

Munthawi yanthawi zonse, chitsulo chokhazikika chimatha kupulumutsa 10% ~ 20% yachitsulo kamodzi, ndi 20% ~ 40% yachitsulo nthawi zambiri. Ndipo prestressed luso dongosolo dongosolo poyerekeza ndi sanali prestressed chikhalidwe chikhalidwe kupulumutsa zitsulo kangapo kwa kangapo. Pomaliza, kukulitsa mphamvu zopangira zida zomangika, kumapangitsa kuti phindu lazachuma lizigwiritsa ntchito prestress. Mwachitsanzo, pali mphamvu zambiri zamphamvu pafupi ndi pakati pa nsonga yokoka ya gawo lolimba la m'mimba. Phindu lazachuma potengera prestress ndilapamwamba kwambiri poyerekeza ndi mtengo wamapangidwe a lattice.

Kuti tikwaniritse zoyembekeza za makasitomala, tili ndi gulu lolimba, chifukwa cha China zitsulo zopangidwa kale mlatho mwadzidzidzi Bailey mlatho kukonzanso kapangidwe kake kuphatikizapo malonda, malonda, kamangidwe, kupanga, kulamulira khalidwe, ma CD, warehousing ndi kukumana, ntchito yabwino wonse, tingathe kukupatsirani mtengo wabwino kwambiri komanso mtundu wabwino kwambiri, chifukwa ndife gulu lokhwima kwambiri!

Timakulandirani kuti mupite ku kampani yathu, fakitale ndi zipinda zathu zowonetsera kuti muwonetse zinthu zosiyanasiyana zomwe zingakwaniritse zomwe mukuyembekezera ndipo, panthawiyi, ndi kupeza mosavuta pa webusaiti yathu, ogulitsa athu adzachita zonse zomwe angathe kuti akupatseni ntchito yabwino kwambiri. Ngati mukufuna zambiri, chonde omasuka kulankhula nafe kudzera imelo kapena foni.
