ʻAnuʻu Manhole

Ua hoʻolālā ʻia nā ʻanuʻu lua no nā lua wai ʻino, nā lua wai ʻino sima a me nā pōhaku lepo, nā waihona wai, nā pahu sima a me ka sima, nā moku, nā kīʻaha, nā loko ʻauʻau, nā lua mines, nā keʻena hoʻokahe wai, nā hale hana, nā kalaka, nā ipu, a pēlā aku.

Ua hoʻolālā ʻia kēia mau ʻanuʻu e hoʻokō me nā kūlana EN13101, e hōʻoiaʻiʻo ana i ka mālama ʻana i nā koi palekana a me ka maikaʻi. Hāʻawi kēia palapala hōʻoia i nā mea hoʻohana i ka maluhia o ka noʻonoʻo me ka ʻike ʻana ua hoʻāʻo pono ʻia a hōʻoia ʻia ka huahana a lākou e hoʻopukapuka nei.

Ua hoʻolālā ʻia ke ʻanuʻu lua no nā limahana hoʻomaʻemaʻe e neʻe i loko a i waho o nā ʻauwai me ka palekana a me ka maʻalahi. Hiki ke hana ʻia me ke kila kalapona, ke kila kila, ke kila corrugated, ka hao ductile, ka hao hoʻolei ʻia, a i ʻole ka alumini. Hiki i ka uhi ke polypropylene copolymer plastic, galvanized, bitumen ʻeleʻele a i ʻole ka uhi epoxy. Hiki i ka uhi ke pale pono i nā ʻanuʻu lua mai ka pala a me ka popo. Loaʻa i ke ʻanuʻu ke kala ʻālohilohi e hōʻoia i ka ʻike kiʻekiʻe. Eia kekahi, loaʻa iā ia ka hiki ke elongation kiʻekiʻe, ke kaomi ukana maikaʻi, ka paʻakikī kiʻekiʻe, ke kūpaʻa kiʻekiʻe.

Hana ʻia mai ka hui pū ʻana o ka polymer polypropylene a me ke kila galvanized, hāʻawi kēia mau ʻanuʻu manhole i ka ikaika kiʻekiʻe a me ke kūpaʻa i ka pala, e hōʻoiaʻiʻo ana i ka hilinaʻi lōʻihi ma nā wahi ʻino loa. Hāʻawi ka uhi polypropylene i kahi ʻili paheʻe ʻole, e hoʻomaikaʻi ana i ka palekana o ka mea hana i ke komo ʻana i loko o ka manhole, ʻoiai ʻo ke kumu kila galvanized e hāʻawi i ke kākoʻo ikaika a me ke kūpaʻa.
