Vim tias lub zog ntawm cov hlau yog siab dua lwm cov khoom siv engineering, cov qauv kev txhawb nqa tseem ceeb ntawm sab nraum zoov LED billboards feem ntau yog ua los ntawm cov ntaub ntawv hlau.Nyob rau hauv qhov chaw qhib huab cua, cov ntaub ntawv hlau tau yooj yim oxidized thiab ua rau corrosion vim yog yam xws li kub, av noo, thiab cov khoom tsis zoo.Corrosion hnyav tuaj yeem txo qhov hnyav-ua haujlwm ntawm cov khoom steel.Yog li ntawd, peb yuav tsum tau Kho thiab ntxiv dag zog rau sab nraum zoov LED billboards.Terence Electronics hauv qab no yuav qhia luv luv txog kev saib xyuas thiab kev txhawb nqa ntawm sab nraum zoov LED billboards.

1. Txoj kev nthuav dav hauv lub hauv paus: nce thaj tsam ntawm lub hauv paus hauv qab ntawm sab nraum zoov LED billboards los ntawm kev teeb tsa cov vaj huam sib luag los yog cov pob zeb ua kom muaj zog, thiab hloov lub hauv paus tsis sib haum xeeb tshwm sim los ntawm thaj tsam me me ntawm cov ntawv tshaj tawm thiab cov kabmob muaj peev xwm tsis txaus.

　　 2. Pit-type underpinning method: ncaj qha ncuav pob zeb tom qab khawb ib lub qhov hauv qab lub hauv paus.

　　3. Pile underpinning method: Cov txheej txheem ntawm kev siv ntau yam ntawm pawg xws li cov kab hluav taws xob zoo li qub, cov pawg uas tau tsav, thiab cov pawg cam khwb cia rau hauv qhov chaw yuav tsum tau siv rau lub hauv paus reinforcement ntawm qhov qis lossis ob sab ntawm lub hauv paus billboard.

　　4. Cov txheej txheem grouting: Txhaj tshuaj lom neeg sib npaug rau hauv lub hauv paus, thiab cov cement thiab ua kom cov av xoob qub los yog cov kab nrib pleb los ntawm cov grouts, txhawm rau txhim kho lub peev xwm ntawm lub hauv paus, tsis muaj dej thiab tsis muaj dej.

　　 Kev kho yog siv cov txuj ci dag kom thim rov qab qaij lub hauv paus inclined kom ua tiav lub hom phiaj ntawm kev kho qhov qaij ntawm sab nraum zoov LED daim duab kos.Cov kev siv feem ntau rau kev kho lub hauv paus ntawm sab nraum zoov billboards yog raws li nram no:

　　 1. Txoj kev kho av thaum muaj xwm txheej ceev: Siv cov kev ntsuas kom tsis txhob muaj kev poob qis ntawm ib sab ntawm sab nraum zoov LED billboard lub hauv paus nrog ntau qhov tawg, thiab siv cov kev ntsuas kev tsaws thaum muaj xwm txheej ceev ntawm sab nraud.Cov txheej txheem ntawm kev yuam kev tsaws suav nrog: kev thauj khoom steel ingots los yog pob zeb, tsim cantilever beams, khawb tawm cov av, thiab rectifying deviations los ntawm kev txhaj tshuaj dej.

　　2. Lifting kho txoj kev: Nyob rau ntawm qhov chaw uas lub hauv paus ntawm inclined billboard muaj ib tug loj subsidence, kho cov lifting nqi ntawm txhua feem ntawm lub billboard kom nws tig raws ib tug taw tes los yog ib tug tej yam txoj kab ncaj nraim mus cuag cov purpose ntawm restoring tus thawj txoj hauj lwm.
