Nānā nui o TRD

Hoʻolauna iā TRD •
ʻO TRD (Trench cutting Re-mixing Deep wall method), kahi hana kūkulu pā mau ma lalo o ka lepo sima mānoanoa like, i hoʻomohala ʻia e ka Kobe Steel o Iapana i ka makahiki 1993, e hoʻohana ana i ka pahu ʻoki kaulahao ʻike e hana mau ai i nā paia mau ma lalo o ka mānoanoa like ʻana o ka lepo sima. .
Ua hiki i ka 56.7m ka hohonu o ke kūkulu ʻana i nā papa one one, a ʻo ka mānoanoa o ka pā he 550mm~850mm. He kūpono hoʻi ia no nā ʻano ʻāpana like ʻole e like me nā ʻiliʻili, ʻiliʻili, a me nā pōhaku.
He ʻokoʻa ʻo TRD i ke ʻano hana paʻa mau ʻano kolamu i kēia manawa ma lalo o ka lepo sima i hana ʻia e nā mīkini hoʻoheheʻe hoʻokahi a i ʻole multi-axis spiral. Hoʻokomo mua ʻo TRD i kahi mea hana ʻoki ʻano kaulahao i loko o ke kumu, ʻeli a hiki i ka hohonu o ka paia i hoʻolālā ʻia, a laila hoʻokomo i kahi lāʻau lapaʻau, hoʻohui ʻia me ka lepo in-situ, a hoʻomau i ka ʻeli ākea a hoʻoulu ʻia, a neʻe i mua a hiki i ka. e kūkulu i kahi kiʻekiʻe kiʻekiʻe e hui pū ana i ka paia mau.

Nā hiʻohiʻona o TRD
(1) Nui ka hohonu o ke kūkulu ʻana; hiki i ka hohonu loa ke hiki i 60m.
(2) He kūpono ia no kahi ākea ākea a he maikaʻi ka hana ʻeli ʻana ma nā ʻāpana paʻakikī (kahi lepo paʻa, ʻiliʻili one, pōhaku palupalu, etc.)
(3) He maikaʻi ka maikaʻi o ka pā i hoʻopau ʻia, ma ke kuhikuhi hohonu o ka pā, hiki iā ia ke hōʻoia i ka maikaʻi o ka lepo sima, hoʻomaikaʻi i ka ikaika, discreteness liʻiliʻi, a me ka hana interception wai maikaʻi.
(4) Palekana kiʻekiʻe, ʻo 10.1m ke kiʻekiʻe o nā mea hana, haʻahaʻa haʻahaʻa o ka umekaumaha, kūpaʻa maikaʻi, kūpono i nā wahi me nā palena kiʻekiʻe.
(5) ʻO ka paia mau me ka liʻiliʻi o nā hono a me ka mānoanoa like o ka pā, hiki ke hoʻonohonoho ʻia ke kila H-like i ka spacing maikaʻi loa.

Kumu o TRD
Hoʻokele ʻia ka pahu ʻoki kaulahao e ka mīkini hydraulic o ka pahu mana, a ua hoʻopili ʻia nā ʻāpana e wili i kahi hohonu i ʻike ʻia, a ua holomua ka ʻeli ʻana. I ka manawa like, hoʻokomo ʻia ka wai paʻa i ka lalo o ka pahu ʻoki e hoʻohui ikaika a hoʻoulu ʻia me ka lepo in-situ, a hiki ke hoʻokomo ʻia ka pā lepo sima i hoʻohui ʻia o ka mānoanoa like i loko o ke kila profile e hoʻonui ai i ka paʻakikī. a me ka ikaika o ka paia hui.
Hoʻololi kēia ʻano hana i ke ʻano hui ʻana o ka pā hui ʻana o ka lepo sima mai ka hui ʻana o ke koʻokoʻo auger axis vertical a hiki i ka hui pū ʻana o ka pahu ʻoki kaulahao ʻike axis horizontal ma ka hohonu o ka pā.
