Mu dziko lomwe likusintha nthawi zonse la zomangamanga ndi zomangamanga, kufunikira kwa zipangizo zogwira ntchito bwino komanso zolimba n'kofunika kwambiri. Limodzi mwa njira zatsopano kwambiri zomwe zapezeka m'zaka zaposachedwa ndi chitoliro cholumikizidwa ndi spiral welded. Ukadaulo uwu sungophatikiza kugwira ntchito bwino ndi mphamvu, komanso umapulumutsa ndalama zambiri, makamaka pa ntchito za mapaipi a zimbudzi. Mu blog iyi, tifufuza momwe tingagwiritsire ntchito mwayi wa mapaipi olumikizidwa ndi spiral welded ndi chifukwa chake ndi chisankho choyamba cha makontrakitala ndi mainjiniya ambiri.
Dziwani zambiri za chitoliro cholumikizidwa mozungulira
Chitoliro cholumikizidwa mozungulira chimapangidwa pogwiritsa ntchito kulumikiza zitsulo zathyathyathya mozungulira kukhala mawonekedwe a tubular. Njirayi imalola kupanga kosalekeza ndipo ndi yachangu komanso yothandiza kwambiri kuposa kulumikiza msoko wowongoka wachikhalidwe. Kapangidwe kapadera ka chitoliro cholumikizidwa mozungulira kamawonjezera kulimba kwa kapangidwe kake, ndikuchipangitsa kukhala choyenera kugwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikiza machitidwe otayira zinyalala, machitidwe operekera madzi, komanso ntchito zomanga nyumba.
Kuphatikiza kwa magwiridwe antchito ndi mphamvu
Chimodzi mwa zinthu zofunika kwambiri pachitoliro chozungulira cholumikizidwandi mphamvu yake yabwino kwambiri yopangira. Kutulutsa kwa chitoliro chimodzi cholumikizidwa mozungulira ndi kofanana ndi mayunitsi 5-8 a chitoliro cholumikizidwa molunjika. Kuchita bwino kwambiri koteroko kumatanthauza kusunga ndalama zambiri pa nthawi ya polojekiti, zomwe zimathandiza makontrakitala kumaliza ntchito mwachangu ndi zinthu zochepa. Pa mapulojekiti a mapaipi amadzimadzi komwe nthawi nthawi zambiri imakhala yofunika kwambiri, kugwira bwino ntchito kumeneku kumatha kusintha kwambiri.
Kuphatikiza apo, mphamvu ya mapaipi olumikizidwa ndi spiral welds siyenera kunyalanyazidwa. Njira yolumikizira spiral imapanga weld yosalekeza, yomwe imawonjezera mphamvu ya paipi yolimbana ndi kupsinjika ndi mphamvu zakunja. Izi zimapangitsa kuti ikhale yabwino kwambiri pamalo ovuta kwambiri, monga malo apansi panthaka omwe angakumane ndi zovuta monga kuyenda kwa nthaka ndi kuthamanga kwa madzi. Kuphatikiza kwa magwiridwe antchito ndi mphamvu kumapangitsa kuti paipi yolumikizidwa ndi spiral welds ikhale chisankho chodalirika pa ntchito iliyonse yomanga.
Yankho lotsika mtengo
Mapaipi olumikizidwa ndi spiral si ogwira ntchito bwino komanso olimba okha, komanso amapatsa makontrakitala njira zotsika mtengo. Ndi chuma chonse cha RMB 680 miliyoni ndi antchito 680, makampani omwe amagwira ntchito yopanga mapaipi olumikizidwa ndi spiral amatha kukwaniritsa ndalama zambiri motero amachepetsa ndalama. Ndi kutulutsa matani 400,000 pachakachitoliro chachitsulo chozungulirandipo phindu lake ndi RMB 1.8 biliyoni, makampaniwa akuwonetsa bwino kuthekera kwa njira yopangirayi.
Mwa kusankha chitoliro cholumikizidwa ndi spiral welded, makontrakitala amatha kuchepetsa mtengo wonse wa mapulojekiti awo pomwe akusungabe mtundu wapamwamba komanso kulimba. Nthawi yosungidwa panthawi yopanga ndi kukhazikitsa ingachepetsenso ndalama zogwirira ntchito, zomwe zimapangitsa chitoliro cholumikizidwa ndi spiral welded kukhala chisankho chabwino kwambiri pamapulojekiti omwe ali ndi bajeti yochepa.
Pomaliza
Zonse pamodzi, mapaipi olumikizidwa ndi spiral amapereka kuphatikiza kwa magwiridwe antchito ndi mphamvu zomwe zimapangitsa kuti zikhale zofunikira kwambiri pakugwiritsa ntchito zomangamanga zamakono komanso zomangamanga. Popeza mapaipiwa amatha kupangidwa mwachangu komanso mopanda mtengo kwambiri, akusintha momwe timagwirira ntchito ndi njira zotsukira zinyalala ndi ntchito zina. Pamene makampaniwa akupitilizabe kusintha, kugwiritsa ntchito njira zatsopano monga mapaipi olumikizidwa ndi spiral ndikofunikira kuti mukhalebe opikisana komanso kukwaniritsa zosowa zamtsogolo. Kaya ndinu kontrakitala, mainjiniya, kapena woyang'anira polojekiti, kuganizira kugwiritsa ntchito mapaipi olumikizidwa ndi spiral pa projekiti yanu yotsatira kudzabweretsa magwiridwe antchito ambiri komanso phindu lopulumutsa ndalama.
