Nā ʻokoʻa i ka hoʻohana ʻana i nā uhi Ductile Iron Manhole D400 a me E600

Hao ductile D400 a me E600 nā uhi lua Loaʻa i kēlā me kēia ko lākou mau pono a me nā hemahema. ʻO ke koho ʻana i ka mea ʻoi aku ka maikaʻi ma muli o ke ʻano hoʻohana a me nā koi.

ʻO ka mea mua, ma ke ʻano o ka hiki ke hali, ʻo ka E600 Uhi lua hiki ke kū i ke kaumaha a hiki i 60 tons, ʻoiaiUhi lua wai D400 he 40 tone ka nui o ke kaumaha. No laila, ʻoi aku ka kūpono o E600 no nā wahi kaʻa nui e like me nā kahua mokulele, nā kahua ukana, a me nā wahi ʻē aʻe e pono ai ke kū i nā ukana kaumaha.

ʻO ka lua, ma ke ʻano o nā mea, hoʻohana pinepine nā uhi lua E600 i nā mea ikaika kiʻekiʻe, kahi e ʻoi aku ai ko lākou paʻa i ka wā e kau ʻia ai nā ukana nui. I ka hoʻohālikelike ʻana, ʻoiai ʻo ka Luawai D400 he paʻa nō hoʻi ka uhi, ʻaʻole haʻahaʻa iki kona ikaika.

ʻO ka mea hope loa, mai ka manaʻo o nā hiʻohiʻona kūpono, ʻo ka D400 uhi lua wai He kūpono ia no nā wahi ukana waena e like me nā alanui nui o ke kūlanakauhale a me nā alaloa nui, ʻoiai ʻo ka E600 he kūpono ia no nā wahi ukana kiʻekiʻe loa e like me nā kahua mokulele a me nā kikowaena ukana. No laila, inā nui ka poʻe e hele ana ma ia wahi a pono paha e kū i nā ukana kaumaha, ʻoi aku ka maikaʻi o ka E600; Ma nā wahi kaʻa haʻahaʻa a i ʻole nā ​​wahi e hala ai nā kaʻa māmā, ua lawa ka D400 no ka hoʻohana ʻana.
