Morero ona ke sebaka sa khoebo sa oval / bophahamo ba limithara tse 40 / bolelele bohle ba limithara tse 441 / bolelele ba limithara tse 90
1. Mokhahlelo oa moralo oa motheo oa morero ona ke Sehlopha sa A, 'me ho sebelisoa liqubu tsa ho epolla ha rotary.
2. Lera la ho jara qetellong ea qubu ke dolomite e senyehileng ka har'a lera ≤4≥, boleng bo tloaelehileng ba ho hanyetsa qetellong ha bo ka tlase ho 5000kPa, bophara ba qubu ke d = 800, 'me sekhahla sa ho bea ke ≥ 0.5m.Kapa ≤3≥2 likarolo tsa letsopa la silty, boleng bo tloaelehileng ba ho hanyetsa qetellong ha bo ka tlase ho 1500kPa, bophara ba qubu d = 800, le bolelele bo sebetsang ba qubu ke ≥35m.
3. Boitsebiso:
(1) Matla a matla a konkreite ea 'mele oa qubu: C30, kaho ea konkreite ea ho tšela metsi ka tlas'a metsi e tla etsoa ho ea ka litlhoko tsa 6.3.26 ~ 6.3.30 tsa "Technical Specification for Building Pile Foundation" JGJ94 .
Mobu oa sebaka o senya hanyenyane mohahong oa motheo oa konkreite le mekoallo ea tšepe mohahong oa konkreite e matlafalitsoeng, 'me mohaho o lokela ho lumellana le "Code for Anti-Corrosion Design of Industrial Buildings" GB50046-2008.
Mehato e tsamaellanang e thibelang ho bola e tla nkoa ho latela lipehelo tse amehang ho Cushion: C15;Pile Cap: C30;Beam ea fatše: C30;Tlhaloso e Akaretsang ea Kholomo Sebopeho se Felletseng.
(2) Litšepe:
HPB300 sehlopha (letšoao: Φ), fy=270MPa;HRB400 sehlopha (letšoao: Φ), fy=360MPa;HRB500 grade (letšoao: Φ), fy=435MPa.
4. Botenya ba lera le sireletsang la matlafatso ea longitudinal ea 'mele oa qubu ke 50mm, mme matlafatso ea longitudinal ea' mele oa qubu e lokela ho kopanngoa ka mochine kapa ho ts'oaroa.
Litlhaloso tsa Kamohelo (GB50204) 5.4.5 le litlhoko tsa 5.4.6.Botenya ba lera la tšireletso la konkreite bo hlalositsoe ho "Basic Component Concrete Protective Layer Thickness Table";tlhaloso e akaretsang ea kholomo e qaqileng sebopeho.
5. Ho lemoha qubu ea Motheo:
(1) Teko ea mojaro:
a.Ho fumana matla a ho jara ka matla a qubu e le 'ngoe, ho sebelisoa teko ea mojaro o tsitsitseng.Boleng bo tloaelehileng ba matla a ho jara a holimo a qubu e le 'ngoe ke 4000KN.
b.Tlas'a maemo a tšoanang (mofuta o mong le o mong oa qubu), palo ea litlhahlobo ha ea lokela ho ba ka tlase ho 3, 'me ha ea lokela ho ba ka tlase ho 1% ea palo eohle ea liqubu;ha palo eohle ea liqubu tsa boenjiniere e le ka har'a 50, ha ea lokela ho ba ka tlase ho 2.
c.Litlhoko tse amehang tsa tlhahlobo li tla ikamahanya le "Tlhahiso ea Technical for Testing of Building Foundation Pile JGJ 106-2014".
