Isingeniso Sephrojekthi kanye nokusebenza kwemikhiqizo

Le phrojekthi iyibhuloho elinobude obungamamitha angu-1,125, futhi ibhuloho elikhulu liyibhokisi lensimbi eline-span elilodwa eliboshwe ngaphansi kwebhuloho eliyikhothamo elinesakhiwo esibanzi esingamamitha angu-170. Ububanzi bebhuloho elikhulu bungamamitha angu-24.1, futhi inkampani yethu ihlinzeka ngokuyinhloko ngemicu yensimbi engaboshiwe engafakwanga egxiviziwe eshisayo kanye nenduku yokubopha insimbi yezintambo zokuhlala ezilengayo kanye nemikhiqizo ehlobene.

Idizayini iyadingeka ukuze ithathelwe indawo. Induku ithatha i-φ15.2-12 kanye ne-φ15.2-14 yensimbi ye-strand bundle extrusion suspension system, i-HDPE sheath cable body. Intambo yensimbi yokubopha ithwala ngokuqondile umthwalo ofile osuka ensikeni eyinhlanganisela kanye nomthwalo ophilayo wezimoto nabantu, okuyisixhumanisi esibalulekile ochungechungeni lokudluliswa kwamandla ebhuloho elikhothamo elisekelwe ngaphansi. Ibanga eliphakathi nendawo elijwayelekile lamabhuloho alengayo eduze kwendawo yokulenga evundlile ye-eksisi yebhuloho ingamamitha ayi-6. Ingxenye engenhla ithatha yonke inqwaba yamahange e-extrusion, futhi indawo engezansi ithatha i-anchorage ene-pin-hinged. Ingaphandle longqimba olungaphandle lwe-HDPE kufanele lwenziwe nge-convex spiral ukuvimbela umoya nemvula ekuvuseni.

Uhlelo lwezintambo ezibophezelayo lwakhiwe umzimba wekhebula lentambo ye-tie kanye nesistimu yokunamathisela, futhi imishayo emibili eyinhloko ngayinye ihlinzekwa ngezintambo zensimbi ezicindezelwe zangaphandle ezingu-4x15.2-9 ukuze zenze uhlelo lwezintambo eziguquguqukayo zesakhiwo; Ukwakhiwa: I-steel tie rod yezintambo ezimisiwe ziyaqina futhi zilungiswe ekugcineni kwe-arch. Ingxenye engenhla ye-suspender ibambelele ku-arch rib, futhi isiphetho esingezansi sigxilwe ku-lug. Intambo yenduku yokubopha ihlelwa ngokulandelana kugongolo oluyinhloko lwe-longitudinal nhlangothi zombili, futhi i-prestress ye-tie rod igxiliwe emikhawulweni yomibili, futhi ukulawulwa okuphindwe kabili kuyamukelwa lapho ukuqina, futhi amandla aqinile akhona, futhi ukunwetshwa kuyengezwa.

Impahla yomzimba wekhebula iwumucu wensimbi oshisayo oshisayo ongahlanganisiwe, futhi amandla omucu wensimbi yi-1860MPa, ehlangabezana nezidingo ze-ASTM A416 kanye ne-GB/T33363-2016 "i-hot-dip galvanized prestressed steel strand"; I-strand yensimbi ihlanganiswe ne-polyester high-strength fiber tape, bese ikhishwa i-double-layer high-density polyethylene (HDPE); Ukusebenza kwesakhiwo kwentambo okusetshenzwa kulengwa kuyo kuhlangabezana nezidingo ezijwayelekile ze-JT/T850-2013 "Amakhebula e-Extrusion & Anchor Steel Strand Tendons"; Ukusebenza kwehange kuhlangabezana nezidingo ezijwayelekile ze-GB/T14370-2015 "Amahange, Ama-Clamps kanye Nezixhumi ze-Prestressed Tendons".
