Khoom muaj nuj nqi
1. Kev rho tawm cov khoom siv hauv tsev nrog cov khoom sib txawv ntawm lub cev, kom lub zog tag nrho thiab kev ua haujlwm ntawm ob lossis ntau dua cov ntaub ntawv tsis ploj, tsis txhob sib tov, tswj tag nrho cov qauv thiab kev ua haujlwm ntawm cov ntaub ntawv, thiab ntxiv dag zog rau lub peev xwm ntawm cov qauv. .
2. Thaum cov dej ntws los ntawm cov khoom siv zoo kos duab rau hauv cov khoom siv ntxhib kos duab, siv cov huab cua zoo permeability ntawm rab koob geotextile kom cov dej ntws los, thiab cuam tshuam cov khoom zoo, cov xuab zeb zoo, pob zeb me me, thiab lwm yam. tswj kev ruaj ntseg ntawm av thiab av engineering.
3. Needle geotextile yog cov ntaub ntawv qhia dej zoo, nws tuaj yeem tsim ib qho kev taw qhia hauv av, tsis suav nrog cov kua thiab roj ntau dhau hauv cov qauv av.
4. Cov av tensile lub zog yog siv los txhim kho lub peev xwm deformation thiab nce kev ruaj ntseg ntawm lub tsev tsim los txhim kho cov av zoo.
5. Ua tau zoo yuav kis tau, hloov mus lossis decompose, tiv thaiv cov av los ntawm kev puas tsuaj los ntawm kev quab yuam sab nraud.
