Cov Pob Tawb Gabion Ob Chav Twisted Hexagonal Mesh tau siv thoob ntiaj teb rau phab ntsa khaws cia, kev ruaj khov ntawm qhov ntxhab, txoj kab hauv av, kev tiv thaiv pob zeb poob thiab ntau lwm yam kev siv tau ntau tshaj 100 xyoo. Vim yog qhov pheej yig thiab kev daws teeb meem mus sij hawm ntev, ob chav twisted mesh gabions muab rau cov kev siv no, lawv siv tau dhau los ua qhov chaw ib txwm muaj nrog ntau lub koom haum tsoomfwv, thiab cov chaw tsim kho av ntiag tug thiab lwm yam ... ntawm no hauv Tebchaws Meskas.
Raws li kev siv gabion loj hlob hauv tebchaws, qhov yuav tsum tau muaj tus qauv kev lag luam ntawm cov khoom zoo tau los ua qhov tseem ceeb kom ntseeg tau tias cov khoom siv sib xws. Lub Koom Haum Asmeskas Cov Khoom Siv thiab Kev Ntsuas tau ntev tau lees paub tias xav tau cov qauv zoo thiab pab cov lag luam hauv kev tsim kom muaj tus qauv kev lag luam rau cov ntaub ntawv thiab cov khoom tshwj xeeb. Lub Koom Haum Asmeskas Cov Khoom Siv thiab Kev Ntsuas (ASTM) luam tawm phau ntawv qhia txog cov lus qhia uas sau txhua cov lus qhia hauv nws hom ntawv tag nrho. Txhua cov lus qhia txog cov khoom lag luam hauv phau ntawv ASTM tau xaiv tus lej qhia rau kev siv. Tus lej qhia ASTM rau Double Twisted Hexagonal Mesh Gabions yog ASTM A975-97.
Cov qauv tag nrho ntawm ASTM A975-97 tsis tau qhia tag nrho. Cov kev cai ua tau zoo ntawm cov khoom tiav thiab cov ntaub ntawv cov ntaub ntawv khoom siv tau sawv cev.
