1. Isigubhu sangaphakathi siyisigubhu esinesakhiwo se-octagonal, esenza umphumela wokuthambisa kwesikhumba esisebenza kahle. I-advanced interlayer yokushisa kagesi nokujikeleza ukujikeleza kuyasetshenziswa. Ngoba uhlelo lokulawula lokulinganisa lokushisa lokushisa, izinga lokushisa lingalawulwa ngokunembe.
2. Ijubane lesigubhu lilawulwa ngokuguqulwa imvamisa kwi-chain. Le drum inemisebenzi yesikhathi yokusebenza okuphelele, phambili nokubuyela emuva emuva nokujikeleza kwesiqondisi esisodwa. Isikhathi sokusebenza okuphelele, phambili nokubuya emuva nesikhathi phakathi kwesikhathi sangemuva nangemuva kungaba yiRegu - kusetshenziswe ngokulandelana ukuze isigubhu singalawulwa ngokulandelana noma ngezikhathi ezithile.
I-3. Iwindi lokubheka lesigubhu senziwe ngengilazi ebonakalayo esobala futhi ephakeme yamandla athambile aqukethe ukumelana okushisa okuphezulu. Kukhona izimbobo ezingena eglayeni lokugeleza kwamahhala komoya ngaphakathi kwesigubhu.
