Mabasiketi ndi matiresi a Double Twisted Hexagonal Mesh Gabion akhala akugwiritsidwa ntchito padziko lonse lapansi poteteza makoma, kukhazikika kwa malo otsetsereka, kuyika mipata, kuteteza miyala ndi ntchito zina zambiri kwa zaka zoposa 100. Chifukwa cha njira yotsika mtengo yogwiritsira ntchito ma gabions a double twisted mesh gabions amapereka ntchito izi, kugwiritsidwa ntchito kwawo kwakhala kofala m'mabungwe ambiri aboma, ndi Private Land Developments etc… kuno ku United States.
Pamene kugwiritsa ntchito ma gabion kukukula mdziko muno, kufunikira kwa muyezo wamakampani wa khalidwe la zinthu kunakhala kofunika kwambiri kuti zitsimikizire kuti zinthuzo zikugwirizana. Bungwe la AMERICAN SOCIETY OF MATERIALS AND TESTING lakhala likudziwika kuti limafuna miyezo yapamwamba komanso kuthandiza mafakitale kukhazikitsa muyezo wamakampani pazinthu ndi zinthu zinazake. Bungwe la AMERICAN SOCIETY OF MATERIALS AND TESTING (ASTM) limafalitsa buku la specification lomwe limalemba specification iliyonse mu mtundu wake wonse. Specification iliyonse ya chinthu mkati mwa buku la ASTM imasankhidwa kukhala nambala ya specification kuti igwiritsidwe ntchito. Specification ya ASTM ya Double Twisted Hexagonal Mesh Gabions ndi ASTM A975-97.
Mtundu wonse wa ASTM A975-97 sunawonetsedwe mokwanira. Zofunikira pakugwira ntchito kwa chinthu chomalizidwa ndi zambiri za deta yake zikuyimiridwa.
ZOFUNIKA PA MPAMVU: ASTM A 975-97
