Amaphrojekthi

1. Ibanga lokuklama isisekelo sale phrojekthi Ikilasi A, futhi kusetshenziswa izinqwaba zokumba ezijikelezayo.

2. Isendlalelo esithwalayo ekugcineni kwenqwaba yi-dolomite enesimo sezulu kungqimba ≤4≥, inani elijwayelekile lokumelana nokuphela kokugcina alikho ngaphansi kuka-5000kPa, ububanzi benqwaba d=800, futhi ungqimba oluthwele ≥ 0.5m.Noma ≤3≥2 izendlalelo zobumba oluthambile, inani elijwayelekile lokumelana nokuphela kokugcina alikho ngaphansi kuka-1500kPa, ububanzi benqwaba d=800, futhi ubude benqwaba obusebenzayo bungu-≥35m.

3.Impahla:

(1) Ibanga lamandla likakhonkolo womzimba wenqwaba: C30, ukwakhiwa kukakhonkolo kokuthululwa kwamanzi ngaphansi kwamanzi kuzokwenziwa ngokuvumelana nezidingo ze-6.3.26 ~ 6.3.30 "I-Technical Specification for Building Pile Foundation" JGJ94 .

Umhlabathi wesayithi ugqwala kancane esakhiweni sikakhonkolo esiyisisekelo kanye nemigoqo yensimbi esakhiweni sikakhonkolo esiqinisiwe, futhi ukwakhiwa kufanele kuhambisane ne "Code for Anti-Corrosion Design of Industrial Buildings" GB50046-2008.

Izinyathelo ezihambisanayo zokunqanda ukugqwala zizothathwa ngokuhambisana nezinhlinzeko ezifanele ku-Cushion: C15;I-Pile Cap: C30;I-Ground Beam: C30;Incazelo Evamile Yekholomu Yesakhiwo Esinemininingwane.

(2) Izinsimbi zensimbi:

Ibanga le-HPB300 (uphawu: Φ), fy=270MPa;Ibanga le-HRB400 (uphawu: Φ), fy=360MPa;Ibanga le-HRB500 (uphawu: Φ), fy=435MPa.

4. Ubukhulu bongqimba oluvikelayo lokuqiniswa kwe-longitudinal yomzimba wenqwaba buyi-50mm, futhi ukuqiniswa kwe-longitudinal yomzimba wenqwaba kufanele kuxhunywe ngomshini noma kuhlanganiswe.

Izicaciso Zokwamukela (GB50204) 5.4.5 kanye nezimfuneko 5.4.6.Ubukhulu bongqimba oluvikelayo lukakhonkolo buchazwe ku-"Basic Component Concrete Protective Thickness Table";incazelo yekholomu enemininingwane yesakhiwo.

5. Ukutholwa kwenqwaba yesisekelo:

(1) Ukuhlolwa komthwalo:

a.Ukuze unqume umthamo wokuthwala ocindezelayo oqondile wenqwaba eyodwa, kusetshenziswa ukuhlolwa komthwalo omile.Inani elijwayelekile lomthamo wokugcina ome mpo wokuthwala wenqwaba eyodwa ngu-4000KN.

b.Ngaphansi kwezimo ezifanayo (uhlobo ngalunye lwenqwaba), inani lokuhlolwa akufanele libe ngaphansi kuka-3, futhi akufanele libe ngaphansi kuka-1% yenani eliphelele lezinqwaba;lapho ingqikithi yezinqwaba zonjiniyela ingaphakathi kwama-50, akufanele ibe ngaphansi kuka-2.

c.Izidingo ezifanele zokuhlolwa zizothobela "Ukucaciswa Kobuchwepheshe Kokuhlolwa Kwenqwaba Yesisekelo Sokwakha JGJ 106-2014".
