150ton Counterweight Choj Erecting Tshuab
A 150-tuj Counterweight Choj Erecting Tshuabyog ib qho zoo kawg nkaus ntawm niaj hnub engineering engineering, ua kom muaj kev nyab xeeb thiab muaj txiaj ntsig kev tsim kho ntawm cov choj loj nyob rau hauv qhov chaw uas nws tau xav tias tsis yooj yim sua. Nws qhov kev tsim kho tshiab tseem ceeb yog kev siv qhov hnyav los tswj lub zog loj uas koom nrog hauv kev tsim tus choj sab nraud los ntawm ib qho chaw.
Nws Ua Haujlwm Li Cas: Kauj Ruam - los ntawm - Cov Txheej Txheem
Kauj Ruam -los ntawm -Txoj Cai Ua Haujlwm (Txoj Kev Ntsuas Cantilever)
Cov txheej txheem rau ib tug pier yog heev methodical:
Kev teeb tsa:Lub tshuab yog sib sau ua ke rau saum tus choj pier, nrog nws cov ceg txhawb nqa ruaj khov.
Segment xa khoom:Ib qho 150-tuj ua ntej- ntu ntu ntu yog xa los ntawm ntau lub qag trailer thiab tso ncaj qha rau hauv qab lub hoists.
Lifting & Counterbalancing:
Lub hoist ntawm ib sab ntawm lub pier nqa ib ntu.
Nyob rau tib lub sij hawm, lub counterweight system ntawm lubrov qabsab yog koom nrog (txawm yog los ntawm kev txav hnyav lossis los ntawm kev muaj qhov ruaj khov uas tsim los rau kev thauj khoom).
Qhov no tsim kom muaj kev sib npaug, zoo li cov saw saw nrog qhov hnyav sib npaug, ua kom lub pier thiab tshuab ruaj khov.
Qhov Chaw & Kev Kho Kom Zoo:Cov ntu yog precisely positioned tiv thaiv lub yav dhau los ntu. High-lub zog epoxy yog siv rau ntawm qhov chaw mating, thiab ib ntus post-tensioning tuav tau nruab los tuav nws hauv qhov chaw.
Balanced Erection:Cov txheej txheem rov ua dua rau ntawmlwm sabntawm lub pier kom muaj symmetry thiab sib npaug. Lub tshuab alternates sab, tso ib ntu ntawm sab laug, tom qab ntawd ib qho ntawm sab xis, thiab lwm yam, ua kom lub tsev tawm ntawm tus choj lawj hauv ob qho tib si.
Ncej -Tensioning:Tom qab ob peb ntu tau muab tso rau, cov leeg sab hauv lossis sab nraud steel yog threaded los ntawm cov ntu thiab tensioned nrog cov jacks loj. Qhov no compresses tag nrho lub rooj sib txoos, tig ib tus neeg mus rau hauv ib qho, muaj zog, tsis tu ncua ncua.
Launching:Thaum lub cantilever ua tiav thiab tuaj yeem txhawb nqa nws tus kheej, lub tshuab raug tshem tawm, txav mus rau pem hauv ntej ntawm lub lawj tsim tshiab, thiab teeb tsa rau ntawm lub nkoj tom ntej kom rov ua tiav tag nrho cov txheej txheem.
