D400 DIManhole uhi me ka huinaha huinahalike

hao haouhi manhole s ua maheleia i poepoe a me ka huinahalike. Ma ke kūlanakauhale, hoʻohana maʻamau ka pōʻai, no ka mea, ʻo ka pōʻaiuhi manhole ʻAʻole maʻalahi ke hili, hiki ke pale maikaʻi i ka palekana o nā mea hele wāwae a me nā kaʻa. ʻO ka hoʻohana ʻana i ka pōʻai ma muli o ka like o ka lōʻihi o ka uhi manhole pōʻai ma waena o kēlā me kēia kikowaena, no laila inā ʻōwili ʻia ka uhi manhole e ke kaʻa e hele ana, e liʻiliʻi iki ke anawaena ma mua o ka luawai ma lalo. . Akea, ʻaʻole e hāʻule ka uhi manhole i ka luawai. Inā hoʻohana ʻia ka huinahā, no ka mea, ʻoi aku ka lōʻihi o ka diagonal o ka huinahā ma mua o ka lōʻihi o kēlā me kēia ʻaoʻao, ke ʻōwili ʻia ka uhi manhole i luna, ua maʻalahi ke hāʻule i loko o ka luawai ma ke ala diagonal o ka luawai. , hoʻopilikia i ka palekana. Inā pōʻai ke poʻo luawai a ʻoi aku ka liʻiliʻi ma mua o ka uhi manhole, ʻaʻole e hāʻule ka uhi manhole square i loko o ka pūnāwai. Pili kēia i ka pilikia o ka hoʻohana ʻana a me ka mālama ʻana i kahi mea. ʻO ka hoʻohana ʻana i ka pūnāwai e pili ana i ka nui o ka luawai. Inā hoʻokomo ʻia kahi uhi manhole square me kahi ʻāpana ʻoi aku ka nui ma mua o ke poʻo punawai, a laila ʻaʻole ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka waiwai a me ka waiwai kūpono ma mua o ka hoʻohana pono ʻana i ka uhi manhole pōʻai, ʻaʻole ia e mālama wale i nā mea o ka uhi manhole. , akā, ua hōʻoia ʻia ka palekana o ka pūnāwai a hoʻohana ʻia ma nā ʻāina a me nā luawai kaula, ma ke ʻano he square, hiki ke pale i ke komo ʻana o nā wai e like me ka wai ua.

Nui
DN400, DN500, DN600, DN700, hoʻopilikino ʻia e like me ke kaha kiʻi.

1. E kūʻē i ka ʻaihue - Composite Manhole Cover me shockproof rubber sealing he non-metallic, non-conductive a non-sparking, ʻaʻohe waiwai o ka hana hou ʻana, hoʻopau loa i nā pilikia ʻaihue.

2. Hiki ke hoʻouka nui — ʻO kona mau mea nui he fiberglass a me ka resin unsaturated. ʻO ka mana oad he A15, B125, C250, D400, E600.

3. Hoʻolālā manuahi-e like me ke kala, Logo, Panel, Load a me Dimension hiki ke hoʻolālā ʻia e like me nā koi o ka mea kūʻai aku.

4. Ola lōʻihi —ʻO ke ola liʻiliʻi he 30 makahiki me ka ʻole o ka mālama.

5. Hoʻopaʻa maikaʻi ʻia - Hiki ke hoʻokomo ʻia me ka hermetically, a pale pono i nā kinoea ʻawaʻawa e kahe ana mai loko mai o ka lua. ʻaʻohe leo pollution a i ʻole rebound.

6. ʻO ka ʻaʻahu maikaʻi a me ka pale ʻana i ka corrosion — ʻAʻole loa ia e ʻōpala no ka mea he maikaʻi kona ʻaʻahu a me ka pale ʻana.

7. Kūleʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa —He insulator maikaʻi loa (mai-40°C~200°C)

8. ʻOi aku ka māmā a me ke kumu kūʻai hoʻokūkū— ʻoi aku ka māmā o ke kaumaha o ka uhi manhole composite, ʻoi aku ka māmā o ka uhi manhole SMC. ʻOi aku ka maʻalahi o ka uhi manhole composite no ka lawe ʻana, hoʻokomo a hoʻoponopono.
