Qhov siab thiab nqa lub peev xwm: Precisely ntsuas thiab xauv rau hauv "kev ua haujlwm ntau"
Lub tsev qhov siab thiab nqa lub peev xwm yog ob qho tseem ceeb hauv kev xaiv ntauwd cranes. Nyob rau hauv cov nqe lus ntawm lifting qhov siab, qhov kawg qhov siab ntawm ntauwd crane yuav tsum coj mus rau hauv tus account tag nrho qhov siab ntawm lub tsev, lub installation qhov siab ntawm lub Cheebtsam, thiab tsim nyog kev nyab xeeb margins. Feem ntau, hauv qab ntawm tus pej thuam crane tus nuv yuav tsum yog 8 mus rau 15 meters saum toj kawg nkaus ntawm lub tsev (rau cam khwb cia- hauv- qhov chaw, nws yuav tsum yog 12-}15 meters siab dua, thiab rau cov qauv, nws yuav tsum yog 8{11}}10 meters siab dua). Rau cov tsev siab siab siab tshaj 200 meters, ib txwm txuas nrog ntauwd cranes tsis txaus thiab nws raug nquahu kom siv cov khoom siv nce toj toj roob hauv pes cranes, ua tiav "ib zaug ua tiav" los ntawm kev nce cov tub ntxhais hauv lub voj voog.
Nyob rau hauv cov nqe lus ntawm load txuam, nws yog ib qho tseem ceeb tsis yog tsuas yog tsom rau lub siab tshaj plaws lifting muaj peev xwm, tab sis kom paub meej txog lub "lifting moment" (lifting peev × ua hauj lwm boom ntev). Thaum xaiv cov khoom siv, ib tus yuav tsum txheeb xyuas cov npe hnyav ntawm cov khoom siv prefabricated, reinforcing tuav, formwork, thiab lwm yam, thiab txheeb xyuas qhov hnyav tshaj plaws thiab nws txoj hauj lwm nqa deb tshaj plaws. Piv txwv li, nyob rau hauv cov tsev prefabricated, vim lub loj ib leeg - thooj hnyav ntawm prefabricated Cheebtsam, lub peev xwm nqa ntawm caj npab kawg yog qhov xav tau heev. Cov kws tshaj lij hauv kev lag luam tau hais tias, thaum ua tau raws li qhov siab tshaj plaws nqa lub peev xwm, lub sijhawm ua haujlwm lifting tiag tiag ntawm ntauwd crane yuav tsum tau tswj xyuas qis dua 75% ntawm lub sijhawm nqa lub sijhawm kom muaj kev nyab xeeb thiab kev pabcuam lub neej ntawm cov khoom siv.
Qhov chaw thiab ib puag ncig: Kho kom haum rau cov xwm txheej hauv zos kom kov yeej "Space Limitations"
Lub cev qhov chaw ntawm qhov chaw tsim kho thiab ib puag ncig ib puag ncig ncaj qha txiav txim siab daim ntawv teeb tsa ntawm ntauwd crane. Rau qhov chaw qhib, tiaj tus- taub hau lossis taw tes- taub hau me me-crawler jib ntauwd cranes yog tus nqi siab heev- xaiv tau zoo, vim tias lawv muaj qhov dav dav thiab cuam tshuam tsawg kawg ntawm ntau lub cranes; thaum nyob rau hauv qhov chaw nqaim xws li hauv nroog cov chaw tseem ceeb, cov lus qhia ntauwd crane tuaj yeem ua haujlwm kom tsis txhob muaj kev cuam tshuam ib puag ncig ua tsaug rau nws lub peev xwm los tig thiab txuas lub caj npab nqa thiab nws cov hneev taw me me.
Tsis tas li ntawd, geological tej yam kev mob ntawm qhov chaw yuav tsis raug ignored. Lub hauv paus ntawm ntauwd crane muaj qhov xav tau siab heev rau lub peev xwm ntawm lub hauv paus. Yog tias muaj lub hauv paus av mos, ua ntej -pile foundation reinforcement yuav tsum tau ua ua ntej. Nyob rau tib lub sijhawm, thaum lub sijhawm npaj thiab teeb tsa, nws yog qhov tsim nyog kom tsis txhob muaj kev tsis sib haum xeeb xws li hauv av tiv thaiv -cov neeg tiv thaiv thaj chaw thiab cov kab ntsaum, thiab xyuas kom muaj kev nyab xeeb kiag li ntawm qhov siab - cov kab hluav taws xob nyob rau hauv lub vojvoog sib hloov.
Pab Pawg Ntauwd Kev Sib Koom Tes thiab Kev Lag Luam: Kev Npaj Ua Haujlwm Ua tiav "Qhov Ua Tau Zoo"
Thaum ntau ntauwd cranes yuav tsum tau ua haujlwm sib koom tes ntawm ib qhov project, kev tiv thaiv kev sib tsoo yuav tsum tau ua raws li nruj me ntsis. Ntauwd cranes uas nyob ib sab yuav tsum tswj kom muaj qhov sib txawv ntawm kab rov tav (Ntau dua lossis sib npaug li 2 meters) thiab qhov siab ntsug qhov sib txawv nrog qhov siab sib txawv (Ntau dua lossis sib npaug li 2 meters txog 6 meters), thiab yuav tsum muaj kev tiv thaiv kev sib tsoo thiab cov khoom siv pom pom pom yuav tsum tau nruab.
Hais txog kev tswj tus nqi, kev xaiv yuav tsum coj mus rau hauv tus account tag nrho cov txiaj ntsig ntawm lub neej. Rau tej yaam num nyob rau hauv 100,000 square meters los yog nrog ib tug luv luv lub sij hawm tsim kho, tus qauv leasing feem ntau muab cov nqi zoo dua; thaum rau tej yaam num kav ntev tshaj 3 xyoos los yog qhov chaw uas lub tuam txhab muaj ib tug tas mus li kev xav tau ntawm prefabricated kev tsim kho, yuav ib tug qauv uas muaj zog versatility yog ntau tus nqi - zoo. Nyob rau tib lub sijhawm, nws raug nquahu kom ua qhov tseem ceeb ntawm kev siv ntauwd cranes nruab nrog lub cev muaj zog sib txawv kom txo tau lub zog siv thiab txhim kho kev tswj hwm kev ruaj ntseg.
