	Zvivharo zvakawanda zvemugodhi zvinogadzirwa kubva kune yakasimba kwazvo ductile iron. Nekuda kwesimba rayo, ductile iron inobvumira mota kuti dzifambe pazvivharo zvemugodhi pasina kutyora kana kukotama, uye vanhu vanogona kufamba vachiyambuka zvakachengetedzeka. Manhole anovhara anogona zvakare kugadzirwa kubva kusimbi yakadhindwa uye epurasitiki.
Kupinda mavhavha uye mahwendefa ekuwana
	Mavhavha ekuongorora uye mahwendefa ekupinda ndiwo mamwe mazita emavhavha emugodhi. Iwo anouya muhukuru hwakasiyana uye ari chikamu cheakasiyana masisitimu epasi pevhu senge pombi dzemvura, tsvina, magetsi uye terevhizheni.
Kudzora ndiro
	Ndiro yekuona kana chivharo chekuona chinotungamira mukamuri yekuona, kazhinji isingadariki 450 mm (17.5 inches) yakafara uye isingadariki 600 mm (24 inches) yakadzika. Dzakaita denderedzwa kana kuti dzakaita rectangular uye dzakashama nekiyi yehatch.
Svika makamera
	Makamuri ekupinda akakura zvekuti munhu akwanise kudhiraivha mvura kana kuita kumwe kugadzirisa.
hatches

Manhole anovhara
	Mamwe mavhavha emugodhi akagadzirwa nepolypropylene, inova ipurasitiki isingaremi uye inogara kwenguva refu; anowanzo kuwanikwa mumigwagwa kana nzvimbo dzevanofamba netsoka. Vanovhura nekuvhara nema screws kana kiyi yepurasitiki isingaremi inosanganisirwa nevhavha yehatch. Vamwe vanhu vanosarudza rudzi urwu rwechivharo chemugodhi nekuti mutengo wekutanga ushoma.
