Ntchito

1. Gawo la mapangidwe a maziko a polojekitiyi ndi Gulu A, ndipo milu yofukula mozungulira imagwiritsidwa ntchito.

2. Chingwe chonyamulira kumapeto kwa mulu ndi dolomite yowonongeka muzitsulo ≤4≥, mtengo wamtengo wapatali wa kukana komaliza ndi osachepera 5000kPa, m'mimba mwake wa mulu ndi d = 800, ndipo wosanjikiza ndi ≥ 0.5m .Kapena ≤3≥2 zigawo za dongo la silty, mtengo wokhazikika wa kukana komaliza sikuchepera 1500kPa, mulu wa m'mimba mwake d=800, ndipo kutalika kwa mulu ndi ≥35m.

3.Zinthu:

(1) Mphamvu ya konkire ya thupi la mulu: C30, kumanga konkire kwa kuthirira pansi pa madzi kudzachitika molingana ndi zofunikira za 6.3.26 ~ 6.3.30 za "Technical Specification for Building Pile Foundation" JGJ94 .

Dothi la malowa limawononga pang'ono pomanga konkriti komanso zitsulo zazitsulo zomwe zimamangidwanso, ndipo zomangazo ziyenera kukhala motsatira "Code for Anti-Corrosion Design of Industrial Buildings" GB50046-2008.

Zogwirizana zotsutsana ndi dzimbiri zidzatengedwa motsatira zomwe zili mu Cushion: C15;Mulu Kapu: C30;Mtsinje wapansi: C30;Mafotokozedwe Azambiri Zagawo Lopanga Mwatsatanetsatane.

(2) Mipiringidzo yachitsulo:

HPB300 kalasi (chizindikiro: Φ), fy=270MPa;HRB400 giredi (chizindikiro: Φ), fy=360MPa;HRB500 giredi (chizindikiro: Φ), fy=435MPa.

4. makulidwe a chitetezo wosanjikiza wa longitudinal kulimbitsa thupi mulu ndi 50mm, ndi kulimbikitsa kotalika wa mulu thupi ayenera umakaniko kugwirizana kapena welded.

Zovomerezeka Zovomerezeka (GB50204) 5.4.5 ndi 5.4.6 zofunika.Makulidwe a konkire woteteza wosanjikiza akufotokozedwa mu "Basic Component Concrete Protective Layer Thickness Table";kufotokoza kwachindunji mwatsatanetsatane kapangidwe kake.

5. Kuzindikira mulu wa maziko:

(1) Mayeso a katundu:

a.Kuti mudziwe kuchuluka kwa kunyamula kwa mulu umodzi, kuyesa kwa static katundu kumagwiritsidwa ntchito.Mtengo wokhazikika wa mulu umodzi wokhazikika ndi 4000KN.

b.Pansi pazikhalidwe zomwezo (mtundu uliwonse wa mulu), chiwerengero cha kuyendera sikuyenera kukhala osachepera 3, ndipo sikuyenera kukhala osachepera 1% ya chiwerengero cha milu;pamene chiwerengero cha milu ya mainjiniya chili mkati mwa 50, sichiyenera kuchepera 2.

c.Zofunikira pakuyezetsa zizigwirizana ndi "Technical Specification for Testing of Building Foundation Pile JGJ 106-2014".
