ʻO wai Paʻa

ʻO ka Surface Box kahi hopena kūpono a paʻa no kāu pono pili kelepona. Hoʻolālā ʻia e pale aku i kāu mau uila a me ke kamaʻilio ʻana mai ka ʻike ʻana i nā mea, ʻoiai i ka manawa like e hiki ai iā lākou ke maʻalahi, ʻo ia ke koho kūpono no kēlā me kēia papahana hoʻonohonoho uea.

Hoʻolālā ʻia ka manhole step no ka hoʻomaʻemaʻe ʻana i nā limahana e neʻe i loko a i waho o nā ʻōpala me ka palekana a me ka maʻalahi. Hiki ke hana ia me ke kila kalapona, ke kila kila, ke kila corrugated, ka hao ductile, ka hao, a me ka alumini. Hiki ke uhi ʻia he polypropylene copolymer plastic, galvanized, bitumen ʻeleʻele a i ʻole ka uhi epoxy. Hiki i ka uhi ke pale pono i nā ʻanuʻu manhole mai ka corrosion a me ka ʻōpala. Loaʻa i ka ʻanuʻu ke kala ʻālohilohi e hōʻoia i ka ʻike kiʻekiʻe. Eia kekahi, loaʻa iā ia ka mana elongation kiʻekiʻe, ke kaomi hoʻouka maikaʻi, ka rigidity kiʻekiʻe, ka lōʻihi kiʻekiʻe.

Hana ʻia mai ka hui pū ʻana o ka polypropylene polymer a me ke kila galvanized, hāʻawi kēia mau ʻanuʻu manhole i ka ikaika kiʻekiʻe a me ka pale ʻana i ka corrosion, e hōʻoiaʻiʻo ana i ka hilinaʻi lōʻihi i loko o nā wahi ʻoi loa. Hāʻawi ka polypropylene coating i kahi ʻaoʻao non-slip, hoʻomaikaʻi i ka palekana o ka mea hana i ke komo ʻana i ka manhole, ʻoiai ke kumu kila galvanized e hāʻawi i ke kākoʻo ikaika a me ke kūpaʻa.

Welina mai i ka honua o EN124 Manhole Cover, kahi huahana i koi ʻia ma waena o nā mea kālepa ma ka honua holoʻokoʻa. Ma ke ʻano he mea hana ma Kina, haʻaheo mākou i ka hāʻawi ʻana i nā uhi manhole kiʻekiʻe i nā mea kālepa ma nā wahi like ʻole o ka honua. Inā ʻoe e ʻimi nei i kahi uhi manhole paʻa, lōʻihi, a me ke kumu kūʻai hiki ke kū i nā kūlana ʻino a me nā kaʻa kaumaha, a laila ʻo EN124 Manhole Cover ka hopena kūpono loa no ʻoe.

I kēia manawa, ua kaulana ka hoʻohana ʻana i nā uhi manhole rectangular ma nā kūlanakauhale. Ma nā wahi ākea, ʻoi aku ka nui o ka hoʻohana ʻana i nā uhi manhole rectangular ma mua o nā mea pōʻai, ma muli o ko lākou maʻalahi o ka hoʻohana ʻana a me ka hoʻohana pono ʻana. ʻO ko lākou ʻano ʻāpana ʻāpana ʻoi aku ka maikaʻi no ka hoʻokomo ʻana i nā wahi kūloko a me ka lōʻihi o ke kaona, a no ka uhi ʻana i nā puka ʻāʻī a i ʻole nā ​​​​hāhā.

ʻO kekahi o nā hiʻohiʻona nui o kā mākou huahana ʻo ia ka maʻalahi o ka hoʻonohonoho ʻana a me ka mālama ʻana. Hoʻolālā ʻia kā mākou Cast Iron Gully Grate a me Frame e hoʻokomo wikiwiki a paʻa e nā poʻe loea i hoʻomaʻamaʻa ʻia, me ka liʻiliʻi o ka hoʻopilikia ʻana i ke kaʻa a i ʻole nā ​​​​hana ʻē aʻe ma ia wahi. Hoʻohui ʻia, ʻo ka ʻili maʻalahi o ka gully grate a me ke kiʻi e maʻalahi ke hoʻomaʻemaʻe a mālama ʻia, e hōʻoiaʻiʻo ana i ka hana pono a me ka maikaʻi i ka manawa.
