Nā papahana

1. ʻO ka papa hoʻolālā kumu o kēia papahana ʻo ka Papa A, a hoʻohana ʻia nā puʻu ʻeli ʻana.

2. ʻO ka papa hana ma ka hopena o ka puʻu ʻo ia ka dolomite weathered i ka papa ≤4≥, ʻo ke kumukūʻai maʻamau o ke kūpaʻa hope loa ʻaʻole i emi iho ma mua o 5000kPa, ʻo ke anawaena o ka puʻu he d = 800, a ʻo ka papa kuhikuhi he ≥ 0.5m.A i ʻole ≤3≥2 ʻāpana o ka pālolo silty, ʻaʻole i emi iho ka waiwai maʻamau o ka hopena hope loa ma mua o 1500kPa, ke anawaena o ka puʻu d=800, a ʻo ka lōʻihi o ka puʻu maikaʻi ʻo ≥35m.

3.Material:

(1) E hoʻokō ʻia ka pae ikaika o ka pahu o ke kino o ka puʻu: C30, ke kūkulu ʻia ʻana o ka wai i lalo o ka wai e like me nā koi o 6.3.26~6.3.30 o ka "Technical Specification for Building Pile Foundation" JGJ94 .

ʻO ka lepo o ka pūnaewele he meaʻino iki i ka hale paʻa kumu a me nā kaola kila i loko o ka hale paʻa i hoʻoikaikaʻia, a pono ke kūkuluʻia e like me ka "Code for Anti-Corrosion Design of Industrial Buildings" GB50046-2008

Pono e hana ʻia nā hana anti-corrosion e like me nā ʻōlelo pili i ka Cushion: C15;Pile Poʻo: C30;Kaola honua: C30;ʻO ka wehewehe nui o ke kolamu kikoʻī kikoʻī.

(2) Nā pahu kila:

Papa HPB300 (hōʻailona: Φ), fy=270MPa;Papa HRB400 (hōʻailona: Φ), fy=360MPa;Papa HRB500 (hōʻailona: Φ), fy=435MPa.

4. ʻO ka mānoanoa o ka pale pale o ka hoʻoikaika lōʻihi o ka puʻu kino he 50mm, aʻo ka hoʻoikaika lōʻihi o ke kino puʻupuʻu pono e hoʻohui me ka mechanically a welded paha.

Nā Manaʻo ʻae ʻia (GB50204) 5.4.5 a me 5.4.6 koi.Hōʻike ʻia ka mānoanoa o ka papa hoʻopaʻa paʻa ma ka "Basic Component Concrete Protective Layer Thickness Table";ka wehewehe nui o ke kolamu kiko kiko.

5. Ka ʻike ʻana i ka puʻu kumu:

(1) Hoʻāʻo hoʻouka:

a.No ka hoʻoholo ʻana i ka hiki ke kau ʻana o ka puʻu hoʻokahi, hoʻohana ʻia kahi hoʻāʻo static load.ʻO ke kumukūʻai maʻamau o ka hikina haʻahaʻa hope loa o ka puʻu hoʻokahi he 4000KN.

b.Ma lalo o nā kūlana like (ʻo kēlā me kēia ʻano puʻupuʻu), ʻaʻole e emi iho ka helu o ka nānā ʻana ma mua o 3, a ʻaʻole e emi iho ma lalo o 1% o ka nui o nā puʻu;inā ʻo ka huina o nā puʻu ʻenekinia i loko o 50, ʻaʻole pono e emi iho ma mua o 2.

c.ʻO nā koi kūpono o ka hoʻāʻo e hoʻokō me ka "Kōnaehana ʻenehana no ka hoʻāʻo ʻana o ka Building Foundation Pile JGJ 106-2014".
