Qhov sib txawv ntawm qhov ntiav faus hydraulic roadblock thiab sib sib zog nqus faus hydraulic roadblock - (2)

Txuas ntxiv los ntawm tsab xov xwm dhau los

3. Yooj yim ntawm kev saib xyuas thiab siv: ntiav faus vs tob faus

Nthuav fausthaiv kev:

• Qhov zoo: Cov khoom siv faus faus yog yooj yim dua rau kev kho thiab tu, tshwj xeeb tshaj yog rau kev tshuaj xyuas thiab kho cov khoom xws li hydraulic systems thiab tswj systems. Txij li thaum cov cuab yeej raug teeb tsa hauv qhov ntiav ntiav, kev khawb av loj hauv av feem ntau tsis tas yuav tsum tau ua.

• Qhov tsis zoo: Cov cuab yeej siv tau yooj yim dua rau kev cuam tshuam ib puag ncig (xws li cov dej tsub zuj zuj thiab sediment) thaum siv, thiab yuav tsum tau them tshwj xeeb rau kev tiv thaiv thaum tu.

Deep buried roadblock:

• Qhov zoo: Vim nws qhov tob loj, cov cuab yeej sib sib zog nqus faus yog qhov cuam tshuam tsawg dua los ntawm qhov chaw ib puag ncig thiab tuaj yeem tswj tau qhov kev ua haujlwm ruaj khov hauv kev siv mus ntev.

• Qhov tsis zoo: Kev saib xyuas cov cuab yeej sib sib zog nqus faus yog qhov nyuaj dua. Yog tias lub kaw lus hydraulic, tswj qhov system thiab lwm yam khoom siv yuav tsum tau kho lossis hloov, qhov faus ntawm cov cuab yeej yuav tsum tau rov ua dua, uas ua rau lub sijhawm thiab nqi ntau ntxiv.

4. Cov chaw siv tau: ntiav faus vs tob faus

Nthuav faus txoj kev thaiv:

• Cov chaw siv tau: Tsim nyog rau cov chaw uas muaj lub voj voog luv luv, qhov chaw nyob hauv av tsawg, thiab hauv av, xws li txoj kev hauv nroog, cov chaw lag luam nkag, thiab qee qhov chaw uas tsis muaj kev tsim kho loj.Nthuav faus txoj kev thaivyog tsim rau ib puag ncig uas xav tau kev txav mus los siab.

tob faustxoj kev thaiv:

• Cov chaw siv tau: Haum rau cov chaw uas muaj kev ruaj ntseg siab heev thiab tuaj yeem tiv taus ntau qhov kev tsim kho, xws li tsoomfwv cov koom haum, cov tub rog hauv paus, cov chaw ruaj ntseg siab, thiab lwm yam. Cov khoom siv sib sib zog nqus faus tuaj yeem ua kom ruaj khov rau lub sijhawm ntev thiab tsis yooj yim cuam tshuam los ntawm kev cuam tshuam sab nraud.

5. Tus nqi sib piv: Pem hauv ntej faus vs. tob faus

Nthuav faustxoj kev thaiv:

• Tus nqi qis: Vim yog qhov tob hauv qhov tob, kev tsim kho yog qhov yooj yim, thiab cov nqi siv hluav taws xob yuav tsum tau qis, uas yog tsim rau cov haujlwm uas muaj peev txheej tsawg.

tob faustxoj kev thaiv:

Tus nqi siab dua: Kev teeb tsa ntawm cov qauv faus tob yuav tsum muaj kev tsim kho ntau dua thiab siv sijhawm ntev dua, yog li nws cov nqi tag nrho yog siab dua, uas yog tsim rau cov haujlwm uas muaj peev nyiaj txaus.

Cov lus qhia xaiv:

• Hom faus ntiav yog tsim rau cov chaw uas xav tau kev xa tawm sai, siv sijhawm luv luv, thiab yooj yim underground foundation. Nws yog qhov tsim nyog rau qee qhov kev tswj xyuas txhua hnub thiab chaw ruaj ntseg.
• Hom kev sib sib zog nqus faus yog tsim rau cov chaw uas muaj kev ruaj ntseg siab heev, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas cov khoom siv yuav tsum tau ua haujlwm ruaj khov rau lub sijhawm ntev thiab tiv taus qhov kev siv siab, nws tuaj yeem muab kev tiv thaiv ntau dua.
