Intshayelelo yeProjekthi kunye nokusebenza kweemveliso-UNIVAC

Le projekthi yibhulorho enobude obupheleleyo be-1,125 yeemitha, kwaye ibhulorho ephambili yibhokisi yentsimbi ene-span enye ebotshelelwe kwibhulorho ye-arch ene-span ye-170 yeemitha. Ububanzi bubonke bebhulorho ephambili ziimitha ezingama-24.1, kwaye inkampani yethu ubukhulu becala ibonelela ngentsimbi eshushu-diphu yagalvanized prestressed unbonded unbonded rod Steel tie stick of suspension stay cables and related products.

Uyilo luyafuneka ukuba luthathe indawo. Intonga ithatha i-φ15.2-12 kunye ne-φ15.2-14 yentsimbi ye-strand bundle extrusion system suspension, i-HDPE sheath cable body. Intambo yentsimbi yokubopha intambo ithwala ngokuthe ngqo umthwalo ofileyo ovela kwi-composite beam kunye nomthwalo ophilayo weemoto kunye nabantu, okuyikhonkco elibalulekileyo kwikhonkco lokuhambisa amandla kwibhulorho ye-arch ephantsi kwenkxaso. Umgama osembindini oqhelekileyo weebhulorho zokuxhoma ecaleni kwendawo yokuxhoma ethe tyaba ye-axis yebhulorho ziimitha ezi-6. Isiphelo esiphezulu sithatha yonke inyanda yee-anchor ze-extrusion, kwaye isiphelo esisezantsi samkela i-anchorage ene-pin-hinged. Umphandle womphandle we-HDPE kufuneka wenziwe nge-convex spiral ukuthintela umoya nemvula ekuvuseleleni.

Inkqubo yentambo ye-tie iqulunqwe ngumzimba wentambo yentambo kunye ne-anchoring system, kwaye iiplanga ezimbini eziphambili zibonelelwa nganye nge-4x15.2-9 i-strands yangaphandle ye-prestressed steel strands ukwenza inkqubo ye-flexible tie rod yesakhiwo; Ulwakhiwo: Intonga yentsimbi yeentambo zokuxhoma igxininiswe kwaye ihlengahlengiswe kwi-arch end. Isiphelo esiphezulu se-suspender sigxininiswe kwi-arch rib, kwaye isiphelo esisezantsi sigxininiswe kwi-lug. Intambo yentambo yokubopha icwangciswe ngokulandelelanayo kumqadi ophambili we-longitudinal kumacala omabini, kwaye i-prestress yentonga yokubopha igxininisekile kuzo zombini iziphelo, kunye nolawulo oluphindwe kabini luyamkelwa xa kuxinzezeleka, kwaye amandla okuqina ahamba phambili, kunye nobude bongezwa.

Izinto eziphathekayo zomzimba wentambo zishushu-dip galvanized unbonded prestressed steel strand, kwaye amandla entsimbi yentsimbi yi-1860MPa, ehlangabezana neemfuno ze-ASTM A416 kunye ne-GB / T33363-2016 "i-hot-dip galvanized prestressed steel strand"; Intsimbi yentsimbi ihlanganiswe nge-polyester ephezulu yokuqina kwe-fiber tape, emva koko i-extruded double-layer high-density polyethylene (HDPE); Ukusebenza kwesakhiwo sentambo ye-anchor ihlangabezana neemfuno eziqhelekileyo ze-JT / T850-2013 "I-Extrusion & Anchor Steel Strand Tendons Cables"; Ukusebenza kwe-anchor kuhlangabezana neemfuno eziqhelekileyo ze-GB / T14370-2015 "Ii-Anchors, i-Clamps kunye ne-Connectors for Prestressed Tendons".
