Iyi purojekiti ndeyeovha yekutengeserana nzvimbo furemu / kureba 40 metres / yakazara kureba 441 metres / yakazara span 90 metres
1. Hwaro hwekugadzira giredhi reprojekiti iyi Kirasi A, uye mirwi yekuchera inotenderera inoshandiswa.
2. Kubata kwekutakura pamagumo emurwi ndeye dolomite yakasvibiswa mumutsara ≤4≥, chiyero chepamusoro chekudzivisa kwekupedzisira kwekupedzisira hakusi pasi pe5000kPa, dhayamita yemurwi ndeye d = 800, uye mutsara wekutakura uri ≥ 0.5m.Kana kuti ≤3≥2 mitsara yevhu ine silty, kukosha kwakajairwa kwekupedzisira kwekupedzisira kuramba hakusi pasi pe1500kPa, murwi dhayamita d=800, uye hurefu hwemurwi hunosvika ≥35m.
3.Zvinhu:
(1) Chikamu chesimba chekrete yemuviri wemurwi: C30, kuvakwa kwekrete kwekudururira pasi pemvura kuchaitwa maererano nezvinodiwa zve 6.3.26 ~ 6.3.30 ye "Technical Specification for Building Pile Foundation" JGJ94 .
Ivhu resaiti iri kushatisa zvishoma kune yekutanga kongiri chimiro uye simbi mabara mune yakasimbiswa kongiri chimiro, uye kuvaka kunofanirwa kuenderana ne "Code yeAnti-Corrosion Dhizaini yeIndustria Zvivakwa" GB50046-2008.
Maitiro ekudzivirira-corrosion anowirirana achatorwa maererano nezvinodiwa muCushion: C15;Murwi Cap: C30;Ground Beam: C30;Tsanangudzo Yakakwana yeColumn Detailed Structure.
(2) Masimbi esimbi:
HPB300 giredhi (chiratidzo: Φ), fy=270MPa;HRB400 giredhi (chiratidzo: Φ), fy=360MPa;HRB500 giredhi (chiratidzo: Φ), fy=435MPa.
4. Kuwanda kwechidziviriro chekudzivirira kwekusimbisa kwelongitudinal kwemuviri wemurwi ndeye 50mm, uye kusimbiswa kwenguva refu kwemuviri wemurwi kunofanira kunge kwakabatanidzwa nemichina kana welded.
Kubvuma Zvinotaurwa (GB50204) 5.4.5 uye 5.4.6 zvinodiwa.Ukobvu hwekongiri yekudzivirira inotsanangurwa mu "Basic Component Concrete Protective Layer Thickness Table";tsananguro yakajairika yekoramu ine udzame chimiro.
5. Kuonekwa kwemurwi wenheyo:
(1) Rodha bvunzo:
a.Kuti uone iyo yakamira yekumanikidza inotakura simba yemurwi mumwe chete, static mutoro bvunzo inoshandiswa.Huwandu hunokosha hweiyo vertical yekupedzisira kubereka kugona kwemurwi mumwe chete ndeye 4000KN.
b.Pasi pemamiriro akafanana (murwi wega wega wega), nhamba yekuongorora haifaniri kunge iri pasi pe3, uye haifaniri kunge iri pasi pe1% yehuwandu hwehuwandu hwehuwandu;kana iyo yese nhamba yeinjiniya mirwi iri mukati memakumi mashanu, haifanirwe kunge iri pasi pe2.
c.Zvinodiwa zvinodikanwa zvebvunzo zvinoenderana ne "Technical Specification yekuyedzwa kweKuvaka Foundation Pile JGJ 106-2014".
