ʻO ka hoʻokomo ʻana i ka puʻu kila Larsen

He aha kaʻO Larsen puʻu pepa kila?
I ka makahiki 1902, ua hana mua kekahi ʻenekinia Kelemania i kapa ʻia ʻo Larsen i kahi ʻano puʻupuʻu kila me ka ʻāpana ʻāpana U a me nā laka ma nā kihi ʻelua, i hoʻohana pono ʻia i ka ʻenekinia, a ua kapa ʻia ʻo "Pile Pepa Larsen"Ma hope o kona inoa. I kēia mau lā, ua ʻike ʻia nā puʻu kila Larsen ma ke ao holoʻokoʻa a hoʻohana nui ʻia i ke kākoʻo lua kumu, nā cofferdams ʻenekinia, pale wai a me nā papahana ʻē aʻe.

ʻO Larsen steel sheet pile he maʻamau maʻamau honua, ʻo ke ʻano like o ka pahu kila Lassen i hana ʻia ma nā ʻāina like ʻole hiki ke hoʻohui ʻia i ka papahana like. ʻO ke kūlana huahana o Larsen steel sheet puʻupuʻu i wehewehe i nā mea a me nā koi e pili ana i ka nui o ke keʻa, ka laka paʻa, ka haku mele, nā waiwai mechanical a me nā kūlana nānā o ka mea, a pono e nānā pono ʻia nā huahana ma ka hale hana. No laila, ʻo Larsen steel sheet pile he hōʻoia maikaʻi maikaʻi a me nā waiwai mechanical, a hiki ke hoʻohana pinepine ʻia e like me nā mea hoʻololi, a he mau mea pono ʻole i ka hōʻoia ʻana i ka maikaʻi o ke kūkulu ʻana a me ka hōʻemi ʻana i ke kumukūʻai o ka papahana.

 

Nā ʻano o nā puʻu ʻili kila Larsen

E like me nā ʻāpana ʻokoʻa ākea, kiʻekiʻe a me ka mānoanoa, hiki ke hoʻokaʻawale ʻia nā puʻu kila Larsen i nā hiʻohiʻona like ʻole, a ʻo ka laulā maikaʻi o kahi puʻu o nā puʻu kila maʻamau i hoʻohana ʻia he ʻekolu mau kikoʻī, ʻo ia hoʻi 400mm, 500mm a me 600mm.
Hiki ke hoʻopilikino ʻia ka lōʻihi o ka Tensile Steel Sheet Pile e like me ka pono o ka papahana, a hiki ke ʻoki ʻia i loko o nā puʻu pōkole a i ʻole welded i loko o nā puʻu lōʻihi ma hope o ke kūʻai ʻana. I ka hiki ʻole ke lawe i nā puʻu kila lōʻihi i ke kahua kūkulu ma muli o ka palena o nā kaʻa a me nā alanui, hiki ke lawe ʻia nā puʻu o ia ʻano i ke kahua kūkulu a laila welded a lōʻihi.
ʻO Larsen puʻupuʻu pahu kila
E like me ka ikaika o ka hoʻoulu ʻana o ka mea, ʻo nā helu waiwai o nā puʻu kila Larsen e like me ke kūlana aupuni ʻo Q295P, Q355P, Q390P, Q420P, Q460P, etc.SY295, SY390, etc. Hiki ke wiliwili ʻia a hoʻolōʻihi ʻia nā pae like ʻole o nā mea, me ka hoʻohui ʻana i kā lākou haku mele. ʻOkoʻa nā māka o nā mea i hoʻohui ʻia me nā mea hoʻohui kemika ʻokoʻa, ʻokoʻa hoʻi kona mau ʻāpana mechanical.

Hoʻohana maʻamau ʻia ʻo Larsen i nā pae waiwai a me nā ʻāpana mechanical
