Kusuma chirongwa
- Iro purojekiti ibhiriji rine hurefu hwakazara hwemamita 1,125, uye bhiriji hombe ibhodhoro resimbi pasi-inotakura bhokisi rakasungirirwa arch bhiriji rine span dhizaini yemamita zana nemakumi manomwe. Hupamhi hwebhiriji hombe ndeye 24.1 metres, uye kambani yedu inonyanya kupa inopisa-dip galvanized prestressed unbonded simbi tambo uye Simbi tie tsvimbo yekumiswa tambo dzekugara uye zvigadzirwa zvinoenderana.
Steel tie tsvimbo yekumisa
- Iyo dhizaini inodiwa kuti inotsiviwa. Tsvimbo inotora φ15.2-12 uye φ15.2-14 simbi strand bundle extrusion suspension system, HDPE sheath cable body. Iyo simbi tie tsvimbo tambo inotakura zvakananga mutoro wakafa kubva kune inoumbwa danda uye mhenyu mutoro wemotokari nevanhu, inova yakakosha chinongedzo musimba rekutumira cheni yepasi-inotsigirwa arch bhiriji. Chinhambwe chepakati chepakati chemabhiriji ekurembera padyo nenzvimbo yakachinjika yekurembera yeakisi yebhiriji mita matanhatu. Mugumo wepamusoro unotora chitsama chezvibatiso zvekuwedzera, uye mugumo wepasi unotora pini-hinged anchorage. Huso hwekunze hwehupamhi hwekunze hweHDPE hunofanirwa kugadzirwa ne convex spiral kudzivirira mhepo nemvura kubva muku manya.
Sunga tsvimbo
- Iyo tie rod system inoumbwa neiyo tie tsvimbo yetambo yemuviri uye anchoring system, uye maviri makuru matanda anopihwa imwe neimwe ine 4x15.2-9 yekunze prestressed simbi tambo kuti iite inochinjika tie tsvimbo yegadziriro; Kuvaka: Iyo simbi tie tsvimbo yeakamisa tambo inosungirirwa uye inogadziriswa pamucheto wearch. Iyo yekumusoro yekupedzisira ye suspender yakasungirirwa mu arch rib, uye mugumo wezasi unosungirirwa kune lug. Iyo tambo yetambo tambo inoteedzana yakarongedzwa muhombe longitudinal danda pamativi ese, uye prestress ye tie tsvimbo inomanikidzwa pamativi ese, uye kutonga kaviri kunogamuchirwa kana tensioning, uye simba rekumanikidza rinokunda, uye kureba kunowedzerwa.
Cable body
- Zvinhu zvemuviri wetambo zvinopisa-dip galvanized unbonded prestressed steel strand, uye kusimba kwesimbi tambo ndeye 1860MPa, iyo inosangana nezvinodiwa zveASTM A416 uye GB/T33363-2016 "hot-dip galvanized prestressed steel strand"; Iyo tambo yesimbi yakaputirwa nepolyester yakakwirira-yakasimba fiber tepi, ndokuzowedzera kaviri-layer high-density polyethylene (HDPE); Kushanda kwemaitiro etambo yeanchor kunosangana nezvinodiwa zveJT / T850-2013 "Extrusion & Anchor Steel Strand Tendons Cables"; Kuita kweancho kunosangana nezvinodiwa zveGB/T14370-2015 "Anchors, Clamps uye Connectors for Prestressed Tendons".
