Cov hniav thoob tiv thaiv feem ntau yog ua los ntawm cov khoom siv uas muaj zog heev, xws li cov hlau sib xyaw tshwj xeeb. Cov ntaub ntawv no muaj kev tiv thaiv kev hnav thiab kev cuam tshuam zoo heev. Thaum lub sijhawm ua haujlwm tiag tiag, thaum cov hniav thoob feem ntau kov cov khoom tawv xws li pob zeb thiab av khov, cov thaiv tiv thaiv tuaj yeem dais feem ntau ntawm kev sib txhuam thiab kev cuam tshuam ua ntej. Yog li, nws txo qhov degree hnav ntawm cov hauv paus ntawmcov hniav thoobthiab ntug ntawm lub thoob, ua rau lub neej ua haujlwm ntawm cov hniav thoob ntev dua thiabthoob.

Tib lub sijhawm, kev teeb tsa thiab kev rhuav tshem ntawm cov thoob hniav tiv thaiv yog qhov yooj yim heev. Lawv txais yuav cov qauv kev sib txuas txheem, xws lintsia hlaukev sib txuas lossis qhov sib txuas, uas ua rau hloov pauv sai tom qab tus tiv thaiv hnav, txo cov khoom siv tsis ua haujlwm, thiab txhim kho kev ua haujlwm zoo. Ntxiv mus, lawv tsim nyog rau ntau yam qauv hniav thoob excavator thiab muaj ntau yam kev siv. Txawm hais tias nyob rau hauv kev khawb av, kev tsim kho, lossis kev ua haujlwm chaw nres nkoj, lawv tuaj yeem ua lub luag haujlwm tiv thaiv tseem ceeb.

Kev xaiv cov khoom siv tiv thaiv hniav zoo tsis yog tsuas yog txo cov nqi kho khoom siv xwb tab sis kuj ua kom ntseeg tau tias kev ua haujlwm khawb av ua tau zoo thiab ruaj khov. Nws yog ib qho kev xaiv tsim nyog los txhim kho kev ua haujlwm ntawm cov khoom siv khawb av.
