Cov yeeb nkab hauv av yog "lub neej" ntawm lub nroog, hais txog qhov tseem ceeb ntawm tib neeg lub neej xws li cov dej hauv tsev thiab cov dej phwj tuaj. Ntawm ntau cov khoom siv yeeb nkab, cov kav hlau yeeb nkab, nrog rau lawv cov kev ua tau zoo tshaj plaws, tau dhau los ua cov khoom siv rau kev tsim kho thiab kho dua tshiab ntawm cov yeeb nkab hauv av, ntsiag to tiv thaiv lub neej ntawm kev ua haujlwm hauv nroog. Niaj hnub no, lawv daim ntawv thov tus nqi nyob rau hauv lub teb chaws underground yeeb nkab network tshaj 90%, dhau los ua ib tug "core" quab yuam txhawb nroog infrastructure.
Kev soj ntsuam ntawm qhov ua tau zoo ntawm cov kav hlau kav hlau
Cov kav hlau kav hlau muaj cov cuab yeej cuab tam nyob ze rau cov kav hlau steel thiab superior corrosion kuj. Lawv cov pob qij txha hloov tau yooj yim pab kev tsim kho, thiab tag nrho cov nqi ntawm qhov project yog qhov tsawg. Hauv kev ua haujlwm hauv cov kav dej, cov kav dej xaim hlau, vim lawv lub siab tawv, tuaj yeem hloov pauv mus rau crustal kev hloov pauv thiab lub zog tam sim ntawd, tsis yooj yim khoov lossis deformed, thiab lawv cov corrosion kuj zoo heev ua rau lub neej ua haujlwm ntev, tsis tshua muaj nqi tu, thiab kev ua haujlwm zoo ib puag ncig.
Nyob rau hauv xyoo tas los no, nrog rau kev nrawm ntawm Tuam Tshoj txoj kev tsim kho nroog thiab kev txhawb nqa ntawm "sponge nroog" kev tsim kho, cov kav dej hlau tau ua tau zoo nyob rau hauv ntau qhov haujlwm loj. Nyob rau theem thib ob ntawm tus kheej- muab qhov kev hloov pauv zoo hauv Beijing lub sub-centre (pib xyoo 2024), kev tsim kom meej meej xav kom cov kav dej loj yog cov kav hlau kav, nrog rau hauv cov dej num loj xws li Sab Qab Teb- mus rau -North Water Diversion Project thiab Hanjiang River{7} Project{7}.
Thawj ob lub ntsiab lus hauv qab no yog cov lus sau tseg.
