Chidebe cha sieve ndi chomangira chofukula chokhala ndi chipolopolo chachitsulo chotseguka chokhala ndi chimango cholimba cha grid kutsogolo ndi mbali.Mosiyana ndi chidebe cholimba, kapangidwe ka gridi kameneka kamalola dothi ndi tinthu ting'onoting'ono kupepeta ndikusunga zinthu zazikulu mkati.Amagwiritsidwa ntchito pochotsa ndi kulekanitsa miyala ndi zinyalala zazikulu kuchokera ku dothi ndi mchenga.
Mwachidziwitso, maziko ndi kumbuyo kwa chidebecho amapangidwa ndi zitsulo zachitsulo zomwe zimagwirizanitsidwa pamodzi kuti zikhale chipolopolo chopanda kanthu.Malinga ndi magulu osiyanasiyana a makina opangira matani komanso zofunikira zosiyanasiyana zomangira, zigoba zakumbuyo zimawotchedwa ndi ndodo zachitsulo ndi mbale zachitsulo mu gululi lotseguka loyambira mainchesi 2 mpaka 6 pakati pa mipata.Enazidebe za mafupamapangidwe ali ndi gululi wam'mbali kuti asefe bwino.
Kupanga:
- Zidebe zimapangidwa kuchokera ku mbale zachitsulo zolimba kwambiri.Izi zimapereka kukhazikika.
- Valani zitsulo zosagwira mbale zitha kugwiritsidwa ntchito m'malo otupa kwambiri.
- Mafelemu a gridi a zipolopolo zakumbuyo za ndowa amawotcherera pamanja kuti azitha kulimba kwambiri.A gululi mafelemu chipolopolo-mbale ndi zitsulo kudula si ovomerezeka.
- Ndodo zachitsulo zolimba zimakhala ndi mphamvu zochepa zokolola za 75ksi kapena 500MPa pomanga grid.
Chidebe cha sieve chimamangiriridwa ku ndodo ya boom kudzera m'malo olumikizirana ndi ma pivot ndi maulalo ngati ndowa wamba.Chingwe chotseguka cha grid chimapereka magwiridwe antchito apadera a kusefa.Pamene chidebe chimalowa mu mulu wa dothi kapena ngalande, dothi lozungulira ndi tinthu tating'onoting'ono timatha kudutsa mumaguluwo pamene miyala, mizu, zinyalala ndi zinthu zina zimadutsa pamaguluwo mu ndowa.Wogwira ntchitoyo amatha kuwongolera kupindika kwa chidebecho ndi ngodya yake pokumba kuti asokoneze zinthu komanso kukulitsa kusefa.Kutseka chidebecho kumasunga zinthu zomwe zasonkhanitsidwa mkati ndikutsegula kumapangitsa dothi losefedwa kuti lizisefa lisanataye.
Zidebe za sieve zimapezeka mumitundu yosiyanasiyana kutengera chitsanzo cha excavator ndi zosowa za mphamvu.Zidebe zing'onozing'ono zokhala ndi 0.5 cubic yard yard ndizoyenera zofukula zazing'ono pomwe mitundu yayikulu ya ma kiyubiki 2 imalumikizidwa ndi zofukula za 80,000lbs zomwe zimagwiritsidwa ntchito pantchito zolemetsa.Kutalikirana pakati pa mipata ya gridi kumatsimikizira momwe kusefa.Zotsegulira ma gridi zimapezeka m'mipata yosiyanasiyana.Kuyang'ana pang'ono kwa mainchesi 2 mpaka 3 ndikoyenera pakusefa dothi ndi mchenga.Mipata yokulirapo ya mainchesi 4 mpaka 6 imalola miyala mpaka mainchesi 6 kudutsa.
Pankhani ya magwiridwe antchito, mawonekedwe a gridi otseguka amathandizira kusefa ndi kusanja mapulogalamu osiyanasiyana:
- Kufukula ndikukweza miyala, mchenga kapena zophatikizika ndikuchotsa zinthu zokulirapo.
- Kulekanitsa nthaka ya pamwamba ndi yapansi posefa miyala ndi zinyalala kuchokera m'mizere yofukulidwa.
- Mwasankha kukumba mizu, zitsa ndi miyala yokhazikika pokumba malo omwe ali ndi zomera.
- Kusankha zinyalala zogwetsa ndi milu yazinthu posefa dothi, chindapusa cha konkriti, ndi zina.
- Kukweza zinthu zosanjidwa m'magalimoto popeza zinthu zazikuluzikulu ndi dothi zachotsedwa.
Mwachidule, chigoba cha chidebe cha sieve chimapangitsa kuti chizitha kukolopa ndikulekanitsa dothi ku zinyalala, miyala, mizu ndi zinthu zina zosafunikira.Kusankha mosamala kukula kwa chidebe ndi malo otalikirana ndi gridi kumathandiza kufananiza magwiridwe antchito ndi mtundu wakufukula ndikusefa komwe mukufuna.Ndi mawonekedwe ake apadera komanso magwiridwe antchito, chidebe cha sieve chosunthika chimapititsa patsogolo zokolola pamitundu yonse yantchito zakusuntha ndi zokumba.
