Mfumo wa nanga wa kujichimba
Kutia nanga hutumiwa sana kwenye handaki kwa usaidizi wa awali, mteremko, pwani, mgodi, miradi ya hifadhi ya maji, Msingi wa jengo, uimarishaji wa barabara na matibabu ya hitilafu ya kijiolojia kama vile ardhi, ufa na umri wa kuzama, haiwezi kubadilishwa katika mazingira finyu ya ujenzi.
FAIDA
Mfumo wa Nanga wa Upau wa Kujichimbia Mwenyewe:
Inajumuisha upau wa uzi ulio na mashimo uliounganishwa na sehemu ya kuchimba visima.Baa ya mashimo inaruhusu hewa na maji kupita kwa uhuru kwenye bar wakati wa kuchimba visima ili kuondoa uchafu, baada ya kuchimba kwa kina kinachohitajika kukamilika, grout inajaza bar mashimo kupitia shinikizo kwa mahitaji yao na inashughulikia kabisa bolt nzima.
Coupler: Coupler inaweza kutumika kuunganisha baa zisizo na mashimo na kupanua urefu wa bolt, inamaanisha kuwa nanga inaweza kuinuliwa na viambatanisho.
Sahani na nati: Sahani na nati huwekwa kulingana na mahitaji yao ya muundo.
Kidogo cha kuchimba visima: Sehemu ya kuchimba visima itachaguliwa kwa chaguo la hali ya ardhi.
