Qhov sib nrug ntawm kev sib txuas ntawm seismic bracing feem ntau yog ib qho brace txhua 12 meters. Rau tag nrho cov kav dej hauv tsev thiab kev tiv thaiv hluav taws xob uas muaj txoj kab uas hla ntawm DN65 lossis loj dua, yuav tsum muaj kev sib tsoo seismic, thiab qhov ntev ntawm cov seismic bracing yuav tsum tau nruab txhua txhua 24 meters. Kev thov ntawm seismic bracing yog nce zuj zus. Nws txoj haujlwm yog txhawm rau txo cov khoom siv vibration, txo qhov kev hloov pauv los ntawm av qeeg, yog li txo qhov kev puas tsuaj rau lub tsev cov dej hauv tsev, dej ntws, kev tiv thaiv hluav taws, cua sov, thiab lwm yam khoom siv hluav taws xob hluav taws xob thaum muaj av qeeg, txo qis kev puas tsuaj thib ob, thiab tiv thaiv cov neeg ua haujlwm kev nyab xeeb.
1. Rau cov kav dej hauv tsev thiab kev tiv thaiv hluav taws uas muaj txoj kab uas hla sib npaug los yog siab dua DN65, nws raug nquahu kom nruab ib qho lateral seismic brace txhua 12 meters thiab ib qho ntev seismic brace txhua 24 meters.
2. Rau tag nrho cov qhov cua duct systems nrog ib txoj kab uas hla ntau tshaj los yog sib npaug zos rau 0.7 meters, lateral seismic bracing yuav tsum tau ntsia ntawm 9 meters, thiab longitudinal seismic bracing ntawm 18 meters.
3. Rau cov khoom siv hluav taws xob thiab cov kab hluav taws xob uas muaj txoj kab uas hla ntau dua lossis sib npaug li 60 mm, thiab tag nrho cov tais cable, cable ladders, cable boxes, thiab busbars nrog lub peev xwm thauj khoom ntau dua lossis sib npaug li 150 N / m, nws raug nquahu kom nruab ib qho kev sib hloov seismic brace txhua 12 meters thiab ib qhov ntev ntawm seismic 2 meters.
Seismic bracing plays lub luag haujlwm tseem ceeb hauv kev tsim seismic. Cov hauv qab no yog cov kev cai rau kev txhim kho seismic bracing:
- Cov cua txias chav kiv cua nrog lub peev xwm thauj khoom ntau dua 1.8 kN thiab cov pa cua nrog tus ntoo khaub lig- thaj tsam ntau dua lossis sib npaug rau 0.38 m² thiab txoj kab uas hla ntau dua lossis sib npaug 0.7 m yuav tsum siv seismic bracing.
- Cov pa taws ua pa, cov pa hluav taws xob thaum muaj xwm ceev, thiab cov cuab yeej muaj feem cuam tshuam kuj yuav tsum tau muaj kev sib tsoo seismic.
- Cov dej hauv tsev, dej kub, thiab cov kav dej tiv thaiv hluav taws uas xav tau kev tiv thaiv seismic, tshwj xeeb tshaj yog cov kav dej kab rov tav nrog txoj kab uas hla ntau dua lossis sib npaug ntawm DN65, yuav tsum tau nruab nrog seismic bracing.
- Hauv siab- cov tsev nce siab nyob rau hauv cov cheeb tsam uas muaj seismic siv ntawm 8 lossis 9 degrees, kev ntsuas seismic yuav tsum tau ua yog tias qhov ntev ntawm cov dej xau thiab cov dej ntws tawm ntau dua 50m; Yog tias qhov ntev ntev tshaj 100m, kev ntsuas seismic yuav tsum tau ua.
- Cov khoom siv hluav taws xob nrog lub taub sab hauv tsis pub tsawg dua 60mm thiab cov tais cable, cable troughs, thiab busbars nrog qhov hnyav tsis tshaj 150N / m yuav tsum tau nruab nrog seismic bracing.
Seismic bracing yuav tsum muaj kev sib txuas ruaj khov rau lub tsev loj. Nws tsim yuav tsum xav txog qhov kev siv dag zog ntawm lub zog ntawm qhov project qhov chaw, nrog seismic quab yuam ua lub ntsiab load, thiab muaj cov thauj tog rau nkoj, reinforcing hangers, seismic kev twb kev txuas Cheebtsam, thiab seismic bracing kab pheeb ces kaum braces. Tag nrho cov khoom yuav tsum tau prefabricated, thiab kev tsim kho ntawm kev sib txuas fasteners yuav tsum yooj yim installation. Seismic kev txhawb nqa rau cov kav dej yuav tsum tsis txhob txwv qhov kev hloov pauv los ntawm thermal expansion thiab contraction, thiab lawv cov installation thiab tsim yuav tsum ua raws li cov lus qhia tshwj xeeb. Txhua qhov kev txhawb nqa seismic yuav tsum muaj kev ntseeg siab txuas nrog lub tuam tsev tseem ceeb, thiab thaum cov kav dej hla lub tsev sib txuas ua ke, cov teebmeem ntawm kev sib haum xeeb yuav tsum raug txiav txim siab.
Rau cov kev tsim kho tshiab, qhov siab tshaj plaws ntawm qhov sib nrug ntawm seismic bracing rau nruj cable ladders, lub voj voog cable tais, thiab cable troughs yuav tsum yog 12 meters, thiab qhov siab tshaj plaws longitudinal spacing yuav tsum yog 24 meters.
