ʻO ka hatch kahi keʻena e hāʻawi ai i nā limahana hoʻoponopono i ke komo ʻana i nā ʻauwai i lawelawe ʻia, nā ʻōpala a me nā pono hana ʻē aʻe. ʻO nā uhi manhole e hūnā i ka puka komo o ke keʻena.
Hana ʻia ka hapa nui o nā uhi manhole mai ka hao ductile lōʻihi loa. Ma muli o kona ikaika, ʻo ka hao ductile e hiki ai i nā kaʻa ke neʻe ma luna o nā uhi manhole me ka ʻole o ka haki ʻana a i ʻole ke kulou ʻana, a hiki i nā kānaka ke hele ma waena o lākou me ka palekana. Hiki ke hana ʻia nā uhi manhole mai ke kila a me ka plastic.
Nā uhi komo a me nā papa komo
ʻO nā uhi nānā a me nā papa komo nā inoa ʻē aʻe no nā uhi manhole. Hele mai lākou ma nā ʻano nui like ʻole a he ʻāpana o nā ʻōnaehana lalo like ʻole e like me ka paipu, ka ʻili wai, ka uila a me ke kīwī.
Papa hoʻomalu
Ke alakaʻi nei kahi pā nānā a i ʻole uhi nānā i ke keʻena nānā, ʻaʻole ma mua o 450 mm (17.5 iniha) ākea a ʻaʻole ʻoi aku ma mua o 600 mm (24 iniha) hohonu. He poepoe a he rectangular a hamama me ke ki puka.
E kiʻi i nā kiʻi paʻi kiʻi
Nui nā keʻena komo no ke kanaka e wili i ka wai a i ʻole e hana i nā mālama ʻē aʻe.
nā hatches
ʻO nā paopao nā keʻena nui loa. Hiki i ke kanaka ke komo i ka ʻōnaehana lalo ma ka puka komo. Hiki i nā manholes ke hohonu, akā ʻo ka nui o ka lua he 600 x 900 mm (62 x 35 iniha). Hana ʻia ko lākou mau poʻi i ka hao nui a loaʻa iā lākou nā ala kī a me nā puka makana (nā āwaha kahi e hiki ai ke hoʻokomo ʻia kahi crowbar e wehe i ke poʻi ma mua o ka hāpai ʻana).
