Chiyambi cha Project ndi magwiridwe antchito
Chiyambi cha polojekiti
- Ntchitoyi ndi mlatho wokhala ndi kutalika kwa mamita 1,125, ndipo mlatho waukulu ndi bokosi lachitsulo lokhala ndi chitsulo chosapanga dzimbiri lomwe limamangiriridwa ndi mlatho wokhala ndi span ya 170 metres. M'lifupi okwana mlatho waukulu ndi mamita 24.1, ndipo kampani yathu makamaka amapereka otentha-kuviika kanasonkhezereka prestressed unbonded zingwe zitsulo ndi Zitsulo tayi ndodo ya kuyimitsidwa zingwe kukhala ndi mankhwala okhudzana.
Chitsulo tayi ndodo ya kuyimitsidwa
- Mapangidwe amafunikira kuti asinthe. Ndodo utenga φ15.2-12 ndi φ15.2-14 zitsulo strand mtolo extrusion kuyimitsidwa dongosolo kuyimitsidwa, HDPE m'chimake chingwe chingwe thupi. Chingwe chachitsulo chomangira ndodo chimanyamula mwachindunji katundu wakufa kuchokera kumtengo wophatikizika ndi katundu wamoyo wa magalimoto ndi anthu, chomwe ndi ulalo wofunikira panjira yotumizira mphamvu ya mlatho wothandizidwa ndi arch. Muyezo wapakati mtunda wa milatho suspenders pa yopingasa yolendewera malo a mlatho olamulira ndi 6 mamita. Kumtunda kumatenga mtolo wonse wa anangula otuluka, ndipo kumunsi kumatengera nangula wa pini-hinged. Kunja kwa gawo lakunja la HDPE kuyenera kupangidwa ndi kozungulira kuti mphepo ndi mvula zisatuluke.
Ndodo yomangira
- Dongosolo la ndodo la tayi limapangidwa ndi chingwe cha tayi ndodo ndi dongosolo loyikirapo, ndipo matabwa awiri akuluakulu amaperekedwa ndi 4x15.2-9 kunja kwa prestressed zitsulo kuti apange dongosolo losinthasintha lazitsulo; Kumanga: Ndodo yachitsulo yachitsulo yazingwe zoyimitsidwa imakhazikika ndikusinthidwa kumapeto kwa arch. Kumtunda kwa suspender kumangiriridwa mu nthiti ya arch, ndipo kumapeto kwapansi kumamangiriridwa ku lug. Chingwe cha ndodo chimayikidwa motsatana mumtengo waukulu wautali kumbali zonse ziwiri, ndipo kuwongolera kwa ndodo kumakhazikika mbali zonse ziwiri, ndipo kuwongolera pawiri kumatengera kukakamiza, ndipo mphamvu yamakokedwe imapambana, ndipo kukweza kumawonjezeredwa.
Thupi la chingwe
- Zinthu za thupi chingwe ndi otentha-kuviika kanasonkhezereka unbonded prestressed zitsulo chingwe, ndi mphamvu ya chingwe chingwe ndi 1860MPa, amene amakwaniritsa zofunika za ASTM A416 ndi GB/T33363-2016 "hot-kuviika kanasonkhezereka prestressed chitsulo chingwe"; Chitsulo chachitsulo chimakulungidwa ndi tepi ya polyester yolimba kwambiri, kenako imatulutsidwa pawiri-wosanjikiza kwambiri polyethylene (HDPE); Mapangidwe a chingwe cha nangula amakwaniritsa zofunikira za JT/T850-2013 "Extrusion & Anchor Steel Strand Tendons Cables"; Kuchita kwa nangula kumakwaniritsa zofunikira za GB/T14370-2015 "Anchors, Clamp and Connectors for Prestressed Tendons".
