Iiprojekthi

1. Ibakala lokuyila isiseko sale projekthi yiKlasi A, kwaye kusetyenziswa iimfumba zokomba ezijikelezayo.

2. Uluhlu lokuthwala kwi-pimple end yi-dolomite edibeneyo kwinqanaba ≤4≥, ixabiso eliqhelekileyo lokumelana nokuphela kokugqibela alikho ngaphantsi kwe-5000kPa, ububanzi bombhobho ngu-d = 800, kunye nomgca wokuthwala ngu≥ 0.5m.Okanye ≤3≥2 umaleko wodongwe olunentlenga, ixabiso eliqhelekileyo lokumelana nokuphela kwesiphelo alikho ngaphantsi kwe-1500kPa, i-diameter ye-pile d = 800, kunye nobude obusebenzayo bemfumba ≥35m.

3. Izinto:

(1) Umgangatho wamandla wekhonkrithi ye-pile body: C30, ukwakhiwa kwekhonkrithi yokugalela ngaphantsi kwamanzi kuya kuqhutywa ngokweemfuno ze-6.3.26 ~ 6.3.30 ze "Inkcazo yobuGcisa kwiSiseko sePile yeSakhiwo" JGJ94 .

Umhlaba wesiza unomhlwa kancinci kwisakhiwo sekhonkrithi esisiseko kunye nemivalo yentsimbi kwisakhiwo sekhonkrithi esomeleziweyo, kwaye ulwakhiwo kufuneka luhambelane ne "Code for Anti-Corrosion Design of Industrial Buildings" GB50046-2008

Imilinganiselo ehambelanayo yokuchasana nokubola iya kuthathwa ngokuhambelana nezibonelelo ezifanelekileyo kwiCushion: C15;I-Pile Cap: C30;Umbhobho ophantsi: C30;INkcazelo ngokuBanzi yeKholam eSakhiwo esineenkcukacha.

(2) Iintsimbi zentsimbi:

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

4. Ubunzima bomgangatho okhuselekileyo wokuqiniswa kwe-longitudinal ye-pile body yi-50mm, kwaye ukuqiniswa kwe-longitudinal ye-pile body kufuneka kudibaniswe ngomatshini okanye i-welded.

IiNgcaciso zoKwamkelwa (GB50204) 5.4.5 kunye 5.4.6 iimfuno.Ubunzima bekhonkrithi yokhuselo lwekhonkrithi luchazwe kwi "Basic Component Concrete Protective Layer Thickness Table";inkcazo jikelele yoluhlu lwesakhiwo esineenkcukacha.

5. Ukubona imfumba yesiseko:

(1) Uvavanyo lomthwalo:

a.Ukumisela umthamo wokuthwala i-vertical compressive ye-pile eyodwa, uvavanyo lomthwalo we-static lusetyenziswa.Ixabiso eliqhelekileyo lomthamo wokuthwala othe nkqo wengqumba enye yi-4000KN.

b.Ngaphantsi kweemeko ezifanayo (uhlobo ngalunye lwemfumba), inani lokuhlolwa akufanele libe ngaphantsi kwe-3, kwaye akufanele libe ngaphantsi kwe-1% yenani elipheleleyo leemfumba;xa inani elipheleleyo leemfumba zobunjineli liphakathi kwama-50, akufanele libe ngaphantsi kwe-2.

c.Iimfuno ezifanelekileyo zovavanyo ziya kuhambelana "neNgcaciso yobuGcisa yoVavanyo lweSiseko seSiseko sePile JGJ 106-2014".
