Nyuma yintebe ya spiral yinkunga y'ibyuma iriho, axis yuzuyemo umurongo uhagaze, gutandukana bihagaritse bigenzurwa muri 20mm, kandi gutandukana kwa hommée bigenzurwa muri 30mm. Itandukaniro ryagati hamwe no gutandukana gutambitse kumpande zombi zidashobora kurenza 20mm cyangwa 1/60 yuburebure. Inkunga ya steel igomba kuba perpendicular hasi kugirango uhuze inkuta. Nyuma yo gukiza birangiye, raporo kuri rwiyemezamirimo rusange yo kwemerwa. Impera zombi zinkunga ya servo zigomba kuba zifite ingamba zo kurwanya zigabanuka, nko gukumira umugozi wo kugwa. Inkunga yicyuma biroroshye kwishyiriraho no gukuraho, gukoresha ibikoresho ni bito, kandi impeshyi zikibo zifatizo zirashobora kugenzurwa neza no gushyira mu bikorwa prestress. Icyuma gishyigikira ibyuma cyihuta, kiba cyiza kugabanya igihe cyo kubaka, ariko rusange gukomera kwa sisitemu yo gushyigikira ibyuma birakomeye. Inkunga y'ibyuma irashobora kwihanganira igitutu, ariko ntabwo ari impagarara, ishobora kubuza neza urutonde rwa diaphragm yo mu nzego zo munsi y'isi mu mwobo w'ifatizo, ariko nta mbaraga zihuje inyuma y'urukuta.
