Mkulu wapamwamba kwambiri wamkati

Mawonekedwe apamwamba kwambiri pamatali a pikha

Kufotokozera kwaifupi:

Zopangidwa kuti zithetse zovuta za zomangamanga zolemera, mawonekedwe athu apamwamba, akulu-akuluakulu amapereka mphamvu ndi kukhazikika pamaziko oyambira. Tekinolory yowuzidwa ndi makina ogwiritsa ntchito popanga njira yomwe timapanga zimatsimikizira kukhala osawoneka bwino komanso olimba, kuchepetsa chiopsezo cholephera ndikukulitsa moyo wa ntchito.

Tumizani imelo kwa ife

Tsatanetsatane wazogulitsa

Matamba a malonda

Timabweretsa mapaipi apamwamba kwambiri, omwe ndi yankho labwino kuti akwaniritse zosowa zomwe zimachitika pomanga ndi zopatsa mphamvu. Monga momwe mafakitale amathandizira kwambiri kukula kwa mapaipi akunja, kufunikira kwa zinthu zolimba komanso zodalirika sikunakhalepo mwachangu. Makonda athu owundana kwambiri ndi miyala iwiri chitoliro chimapangidwa kuti chikwaniritse izi, ndikuwonetsetsa kwambiri komanso kukhazikika pakugwiritsa ntchito mitundu yosiyanasiyana.

Zopangidwa kuti zithe kupirira zolimba za zomangamanga zolemera, mkhalidwe wathu wapamwamba kwambiri,Mapaipi akuluakuluperekani mphamvu ndi kukhazikika kofunikira pakuthandizidwa. Tekinolory yowuzidwa ndi makina ogwiritsa ntchito popanga njira yomwe timapanga zimatsimikizira kukhala osawoneka bwino komanso olimba, kuchepetsa chiopsezo cholephera ndikukulitsa moyo wa ntchito. Kaya mukuchita nawo ntchito zamalonda, okhalamo, malo omwe ali ndi ziphuphu zathu ndi chisankho chabwino kuti mukwaniritse zosowa zanu.

Phindu lazinthu

Chimodzi mwazinthu zabwino kwambiri pogwiritsa ntchito mapaipi ang'onoawiri ndi kuthekera kwawo kupirira katundu wolemera. Mapaipi awa amapangidwa kuti azitha kupirira kukakamizidwa kwambiri, kuwapanga kukhala abwino pakugwiritsa ntchito maziko a m'ma pomanga akulu pantchito zomanga. Malirimita awo amawonjezeranso malo okhala pansi, potero amalimbikitsa kukhazikika ndikuchepetsa zovuta zina. Kuphatikiza apo, njira yophukira yowirikiza yomwe imagwiritsidwa ntchito popanga ziphuphu izi zimatsimikizira kuti ndi mphamvu yolimba komanso yolimba, yochepetsera chiopsezo cha kulephera kwa mankhwala.

Kuperewera

Mtengo wopanga chitoliro chapamwamba kwambiri chimatha kukhala chapamwamba kuposa njira zachikhalidwe, zomwe zingakhudze bajeti.

Kuphatikiza apo, njira kukhazikitsa zitha kukhala zovuta komanso zowononga nthawi, zomwe zimafuna zida zamakono ndi ogwira ntchito aluso. Ngati sichingayang'anitsidwe moyenera, izi zitha kuyambitsa kuchepa kwa malo opangira ma polojekiti.

Karata yanchito

Munthawi yomanga yomanga ndi kupatsirana kwapamwamba, kufunika kwa zinthu zolimba ndikofunikira. Zinthu zina zomwe zalandira chidwi kwambiri ndizokwera kwambiri, matumba akuluakulu. Monga momwe ntchito zopangira zopangira zimawonjezera kukula ndi zovuta, kufunikira kwa njira zokulirapo, zothetsera mavuto zimakhala zolimba.

Ndi chitukuko chachangu cha ntchito za m'matumba ndi zomangamanga, m'mimba mwake ya zilonda zam'mimba zikupitilira kukwaniritsa zosowa zamakono zamakono. Owoneka bwino kwambirichitoliro chachikulu chachitsuloMilu ndiyofunikira kuti mupereke chithandizo chofunikira komanso kukhazikika kwa zida zosiyanasiyana monga milatho, nyumba ndi malo omangira m'madzi. Mapaipi awa amapangidwa kuti azitha kupirira katundu wambiri komanso mikhalidwe yankhanza zachilengedwe, kuonetsetsa kukhala ndi moyo wabwino komanso chitetezo chomwe akufuna.

Pamene makampani omanga akupitilirabe kusinthika, kufunikira kwa chitoliro chapamwamba kwambiri chamiyala yayikulu sikungafanane. Kudzipereka kwathu kwabwino komanso kutulutsa nzeru kumawathandiza kukhalabe odalirika ku mafakitale omanga, omwe amapereka zinthu zofunika kwambiri pazomanga mtsogolo. Kaya mukuchita nawo ntchito yayikulu kapena ntchito yaying'ono yomanga, mapaipi athu akuluakulu amakupatsani mphamvu ndi kudalirika komwe mungafunike.

Q1: Kodi chitoliro chachikulu chimakhala chiyani?

Mapaipi akuluakulu amakamba ndi magulu a cylindrical omwe amagwiritsidwa ntchito pothandizira katundu wolemera pantchito zomanga. Dongosolo lawo lowonjezereka limapereka mphamvu zambiri ndipo ndiyabwino pamadera akuya potsutsa nthaka.

Q2: Chifukwa chiyani kusankha skierst yachitsulo pazithunzi?

Makina owoneka bwino achitsulo amadziwika chifukwa champhamvu komanso kulimba. Njira yowuzira yotentha yotentha imatsimikizira kuti kusungulumwa mosalekeza, komwe kumawonjezera umphupi wa utoto. Njira iyi imalolanso kupanga mapaipi achitsulo akuluakulu kuti mukwaniritse zofuna za zomangamanga zamakono.

Q3: Kodi mapaipi awa amapangidwa kuti?

Mapaipi athu ambiri okhala ndi masamba ophatikizidwa amapangidwa ku Cangzhou, Hebei Dera. Fakitale yathu idakhazikitsidwa mu 1993 ndikuphimba gawo la 350,000 mita ndi zinthu zonse za RMB 680 miliyoni. Tili ndi antchito odzipereka odzipereka 680 odzipereka kuti apangitse njira zothetsera mavuto omwe amakwaniritsa zofuna za malonda omanga.
