Ka hihia a ke awa ʻo Djibouti

Aia ka Lepupalika o Djibouti ma ke kahakai komohana o ke Kaiwa o Aden ma ka hikina akau o Aferika. ʻO ke kowaʻo Mande, ke kī o ke Kaiʻula e komo ana i ka Moana Inia, ua palena ʻia e Somalia ma ka hikina hema, Eritrea ma ka ʻākau, a me ʻAitiopa ma ke komohana, ke komohana hema a me ka hema. ʻO ka palena ʻāina he 520 mau kilomita ka lōʻihi, ʻo ke kahakai he 372 mau kilomita ka lōʻihi, a ʻo ka ʻāina he 23,200 kilomika square.

ʻO Djibouti kekahi o nā ʻāina liʻiliʻi loa o ka honua. He ʻilihune nā kumuwaiwai kūlohelohe, nāwaliwali nā kumu ʻoihana a me ka mahiʻai, a ʻoi aku ma mua o 95% o nā huahana mahiʻai a me nā ʻoihana e hilinaʻi nei i ka lawe ʻana mai. ʻO nā ʻoihana kaʻa kaʻa, kālepa, a me nā ʻoihana lawelawe (ʻoi aku ka nui o nā lawelawe awa) ma luna o ka hoʻokele waiwai, e helu ana ma kahi o 80% o GDP. He kūlana koʻikoʻi nā awa a me nā kaʻa kaʻaahi i ka ʻoihana aupuni.
ʻO ke awa ʻo Djibouti kekahi o nā awa koʻikoʻi ma ʻApelika Hikina. E like me kā mākou i ʻike ai, ʻo ke awa ka hui o ka lawe ʻana i ke kai a me ka ʻāina a me ke kumu o nā hana ʻoihana; ua lilo ke awa i kikowaena o nā logistics i hoʻohui ʻia; ʻo ke awa ka wahi ulu o ka hoʻomohala kūlanakauhale; ʻO ke awa ka hopena o ka hoʻoikaika ʻana i ka nohona a me ka hoʻokele waiwai. Ua koho ka papahana auwai o Djibouti i kā mākou auwai wai resin, he 1082 mau mika, a ua hoʻohālikelike ʻia me F900 ductile iron cover plate, i kūpono no ka hoʻohana ʻana i ka pā uhi uhi kiʻekiʻe i nā manawa e like me nā mokulele a me nā awa.

ʻO nā hiʻohiʻona o ke kahawai wai resin

1. ʻO ke kahawai wai wai resin he mea resin i kū i ka waika a me ka alkali, ka ʻino kemika, ke kūpaʻa ʻana, a me ke kūpaʻa maikaʻi o ka nohona. Hiki iā ia ke hoʻopaʻa i ke kaiapuni paʻakikī o ke awa a pale i ka wai kai mai ka hoʻopau ʻana i ke kahawai wai.

2. Ke hoʻohana nei ka pā uhi i kā mākou F900 ductile iron cover plate, nona ka mana kiʻekiʻe loa, hiki ke hoʻokō i nā koi koi o ka ukana a me nā kaʻa i ke awa. Eia kekahi, hiki ke hoʻonui ʻia ke ola lawelawe o ke kahawai wai.

3. Hoʻohana ke kahawai wai resin i kahi hoʻolālā laina a loaʻa kahi hiʻohiʻona lokomaikaʻi; ʻO ka ʻāpana keʻa o ke kino ʻauwai he ʻano U, me ka wai nui; ʻO ka paia o loko o ke kahawai wai maʻemaʻe, ʻaʻole maʻalahi ka haʻalele ʻana i ka ʻōpala, a ʻoi aku ka maikaʻi o ka hoʻokele waiwai.

4. He lōʻihi kēia papahana ma ʻApelika, a he lōʻihi ke kaʻina hana. Hoʻokumu pū ʻia kā mākou kahawai wai resin i loko o ka hale hana, a ʻoi aku ka maʻalahi o ke kaumaha ma mua o ke kahawai hoʻoheheʻe paʻa maʻamau, ʻokoʻa nā kikoʻī, ʻoi aku ka maʻalahi o ka lawe ʻana, a ʻoi aku ka haʻahaʻa o ke kumukūʻai.

5. ʻAʻole kaulana loa ke kahawai wai Resin ma Kina, akā he huahana kaulana hoʻi ma waho. I ka hōʻike hope loa, ʻo ia ka maikaʻi o ka maikaʻi a ua ʻike ʻia ma ka home a ma waho. He huahana kūpono no ke kūkulu ʻana i nā kūlanakauhale sponge ma koʻu ʻāina.
No laila hiki iā mākou ke ʻike e hiki ke hoʻohana ʻia kā mākou kahawai wai resin ma nā wahi he nui, a kaulana hoʻi a makemake ʻia i kekahi mau wahi me nā koi haʻahaʻa kiʻekiʻe. Eia kekahi laʻana, nā kahua mokulele, nā kīhāpai aupuni, nā alaloa, a me kekahi mau alanui e pono ai ke hele i nā kaʻa nui e like me nā kaʻa ahi. Hāʻawi ʻo Resin drainage i nā mea hou no kā mākou kūkulu ʻana i ka wai me kāna hana ʻoi aku ka maikaʻi.
