Shanghai Qinkai Industry Co., Ltd. Muab Kev Xam Xyuas Kev Txhawb Nqa Av Qeeg Siab Rau St. Lucia Halls of Justice Project

CASTRIES, St. Lucia & SHANGHAI, Suav teb — Hauv kev txhim kho loj rau Caribbean infrastructure thiab kev nyab xeeb rau pej xeem, Shanghai Qinkai Industry Co., Ltd., lub tuam txhab tsim khoom thoob ntiaj teb thiab tus tsim qauv ntawm kev tswj hwm cable thiab cov txheej txheem txhawb nqa seismic, tau ua tiav xa daim ntawv qhia txog Seismic Support Design thiab Calculation Report rau qhov project St. Lucia Halls of Justice (HOJ) uas muaj koob npe nrov. piav qhia txog kev tsim kho tshuab, kev suav thauj khoom, thiab kev txheeb xyuas kev nyab xeeb ntawm cov qauv uas tau ua rau cov txheej txheem txhawb nqa seismic uas raug ncua hauv lub tsev hais plaub tseem ceeb. Daim ntawv pov thawj qauv no sawv cev rau lub hom phiaj tseem ceeb, ua kom ntseeg tau tias cov khoom siv hluav taws xob tseem ceeb ntawm St. Lucia lub tsev hais plaub tseem ceeb tuaj yeem tiv taus cov xwm txheej av qeeg thiab tswj kev ua haujlwm txuas ntxiv thaum muaj xwm txheej ceev.

Lub Luag Haujlwm Tseem Ceeb ntawm Kev Tsim Kho Av Qeeg hauv Kev Tsim Kho Vaj Tse rau Pej Xeem

Cov tsev pej xeem thiab cov tsev kawm ntawv niaj hnub xav tau ntau dua li qhov zoo nkauj thiab kev ruaj khov ntawm cov qauv; lawv xav tau kev ua haujlwm siab tiv thaiv av qeeg. Qhov no yog qhov tseeb tshwj xeeb rau cov chaw hais plaub, kev tswj hwm, thiab xwm txheej ceev xws li St. Lucia Halls of Justice, uas ua haujlwm ua cov chaw tseem ceeb rau tsoomfwv hauv zos. Hauv cov cheeb tsam uas muaj kev ua ub no geological, kev tiv thaiv cov khoom tsis yog cov qauv - xws li cov tais cable qis thiab siab, cov kav dej, thiab HVAC - yog qhov kev nyab xeeb tseem ceeb.

Thaum muaj av qeeg, cov khoom siv uas tsis tau kho lossis tsis tau xam zoo yuav co tau hnyav heev, ua rau muaj kev puas tsuaj rau cov qauv, hluav taws xob raug txiav, thiab muaj kev phom sij loj rau cov neeg nyob hauv tsev. Cov txheej txheem txhawb nqa av qeeg ua haujlwm zoo li cov hlau khi uas tswj kev txav mus los sab thiab sab ntev, faib cov khoom thauj rov qab mus rau hauv cov qauv pob zeb tseem ceeb kom muaj kev nyab xeeb.

Yuav kom ua tau raws li cov kev cai nyab xeeb no, Shanghai Qinkai Industry Co., Ltd. tau siv cov qauv kev teeb tsa thoob ntiaj teb thiab hauv tebchaws. Cov qauv tsim engineering rau HOJ project suav nrog:

• GB50017-2003: Cov Cai rau Kev Tsim Cov Qauv Hlau
• GB50009-2001: Cov Cai rau Kev Tsim Khoom Siv ntawm Cov Qauv Tsev
